Product Description

Double arm resin sand mixer introduction:

The resin sand mixer is mainly composed of low-speed sand mixing cage, high-speed sand mixing cage, base, sand hopper, liquid material conveying system, air pipe system, electric control operating system and sand quantitative system. The key component is a high-speed sand mixing cage shell that can be opened in the left and right directions to facilitate cleaning.Abrasive resistant materials are surfacing on the surface of the mixing tool, and the layout of the mixing tool has a certain Angle. In the process of use, when there is any change, the machine should stop and adjust the Angle.
Because resin sand mixer takes curing agent as hardening agent, and curing agent is a kind of weak acid, which has corrosiveness to a certain extent, it is necessary to take protective measures in the process of adding.Resin sand mixer used for conveying curing agent metering pump also requires strong corrosion resistance, it isrecommended to use Italy OBL original mechanical diaphragm pump.

Main structure and working principle

The resin sand mixer consists of a base, a sand mixing mechanism, a binder system, an air system, and an electrical system.

1.Base: supports and fixes various components such as the sand mixing mechanism, adhesive system, pneumatic system, electrical system, etc.

2. Sand mixing mechanism: It consists of a first stage sand mixing cage and a second stage sand mixing cage. The sand mixing mechanism is connected to the base and between the two stages of sand mixing cages with 4-point rotary bearings.

(1)Primary sand mixing cage: The deceleration motor drives the cage shaft to rotate through an elastic coupling, and the sand that enters quantitatively from the sand inlet is conveyed forward by the spiral blades to the secondary sand mixing cage.

(2)Secondary sand mixing cage: The cage shaft is driven by the motor seat elastic coupling to rotate. The sand fed by the primary cage is transported forward through the spiral blades to the sand mixing starting section. A curing agent is added from outside the proximal control valve, and pre mixed through the small blades to the proximal control valve where resin is added before entering the sand mixing section. The small blades of the sand mixing section are adjustable, which can adjust the gap between the blades and the mixing cage wall to compensate for the increased gap caused by wear, and adjust the angle between the blades and the axis to change the direction and speed of sand movement, thereby enhancing the interpenetration ability between sand particles and achieving a more ideal sand mixing effect.

3. Adhesive system: composed of gear pump, variable diaphragm pump, proximal control valve, and piping system. (1) Gear pump: This pump is a fixed flow low-pressure gear pump with high volumetric efficiency and reliable operation. (2) Electric variable diaphragm pump, also known as variable chemical pump, is currently one of the more advanced low-pressure precision micro pumps in China. Its flow rate is stable and reliable, and it is resistant to acid and alkali. (3) Near end control valve: The rubber valve plate is driven by a cylinder to open and close the adhesive working valve. When the sand mixing is stopped and the working door is closed, the one-way valve opens to blow out the adhesive in the output channel, while the working chamber and input pipeline are still filled with adhesive, minimizing pipeline losses. Therefore, the adhesive can be added immediately during the next sand mixing.

4. Air circuit control system: composed of directional valve, cylinder, and piping system, it realizes the control of
rotary braking, proximal control valve, positioning pin, sand discharge gate and other components.

5. Electric control system: The sand mixer is an important equipment in the resin sand production line. The machine mixes the molding sand (or pure old sand or pure new sand, or new and old sand in various proportions) with the corresponding weight of resin and curing agent (acid) and stirs them evenly before shaping. The electrical load of the sand mixer is mainly the electrically controlled motor, followed by the electrically controlled air valve. There is an isolation transformer in the system to improve the quality indicators of the control power supply.

5.1 The system adopts advanced programmable logic controller (PLC), contactless control, and the signals sent by the main control devices (buttons, knobs, and position electronic detection switches, etc.) are scanned by the PLC machine to form the logic and time electrical control of the sand mixer (i.e., user program control is achieved through the functions of the PLC machine).

5.2 The normal state of each motor (i.e. each protection switch is in the normal position) and the closing position of the mixing cage are taken as the operating prerequisites of the PLC machine in the system. When an abnormal emergency situation occurs during the operation of the sand mixer, Chi can manually stop the operation of the PLC machine immediately. The
operation of the sand mixer is also equipped with a chain link for the sand position of the sand hopper.

5.3 The system is equipped with a simulation screen that displays the operating status of the sand mixer and some abnormal states. The electrical control of the sand mixer can be divided into two parts: automatic and single action.

Main Features of resin sand mixer:

1) The two-arm continuous resin (sand) sand mixer is a single sand mixer. The machine is composed of a primary conveying agitator and a secondary sand mixing agitator.Low speed conveyor is adopted for the agitator, and high speed mixing is adopted for the agitator.

2) The mixing cage is made of fully open cemented carbide welded on sand mixing blades with a service life of over 2000 hours.

3) The liquid material is transported by mechanical diaphragm metering pump imported from Italy to transport curing agent (curing agent pump), and gear pump (with stepless variable speed motor) to transport resin, or according to the user's requirements all choose imported gear pump for transport.

4) The mixed sand head tailings are very small, and the electrical control system is controlled by imported PLC to ensure 100% operation rate of the machine.

5) Liquid material conveying valve (commonly known as proximal control valve) can be selected anti-corrosion liquid material reversing valve (backflow valve), the valve can do stop pump, sand mixer working valve in the working position when not working hit the backflow position, then work again hit the working position, to solve the problem of too much tailings when frequently open the pump head. The liquid material is sprayed into a fan-shaped fog belt by compressed air, making it easier for the binder to mix with sand quickly and evenly. You can also choose the back blowing valve with the back blowing function.
