Description

Technical Field

[0001] This utility model relates to the field of colloid production technology, specifically to a colloid grinding device. Background Technology

[0002] Colloids are a class of dispersion systems in which the particle diameter of the dispersed phase is between that of coarse dispersions and solutions. They are highly dispersed, multiphase, and heterogeneous systems with wide applications in numerous fields. In the production of colloids, grinding equipment is one of the key pieces of equipment; however, existing colloid grinding equipment still has certain shortcomings, such as:

[0003] The "Colloid Mill Grinding Device" with application number CN202220647639.9 cannot achieve the circulation and re-grinding of the grinding material during use. As a result, the material is directly discharged after a single grinding. For some hard or high-requirement colloidal materials, it is often difficult to achieve the ideal grinding fineness, resulting in insufficient and uneven grinding of the material, which will affect the grinding effect of the colloid and is not conducive to ensuring the quality of colloidal products, thus limiting its use. Utility Model Content

[0004] The purpose of this invention is to provide a colloid grinding device to solve the problem mentioned in the background art that existing grinding devices cannot perform cyclic grinding of materials, resulting in insufficient grinding of materials.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a colloid grinding device, including a grinding box, on the bottom surface of which a support leg is fixedly installed;

[0006] The grinding box has a feed hopper fixedly installed at the top and a discharge pipe fixedly installed at the bottom center. A discharge valve is installed on the discharge pipe. A hollow tube is longitudinally movably installed at the top center of the grinding box, and a grinding block is fixedly installed at the bottom end of the hollow tube. A drive mechanism for its rotation is connected to the top of the hollow tube.

[0007] The left side of the grinding box is provided with a material return mechanism for material circulation, and the top of the material return mechanism is connected to a transmission mechanism. The transmission mechanism is connected to the drive mechanism and is used for the lifting and moving of the hollow tube.

[0008] The above technical solution facilitates the full and effective circulation and grinding of materials, improving the effect and efficiency of colloid grinding.

[0009] As a preferred embodiment of this invention, the top of the grinding block is a conical surface.

[0010] The above technical solution facilitates the dispersion of materials in all directions when the grinding block rotates.

[0011] As a preferred technical solution of this utility model, the driving mechanism includes a frame, which is fixedly installed on the top surface of the grinding box, and a motor is fixedly installed on the inner top surface of the frame. The shaft end of the motor is keyed to a rotating shaft, and a driving rod is coaxially fixedly installed at the bottom end of the rotating shaft. The driving rod extends movably into the interior of the hollow tube.

[0012] By adopting the above technical solution, it is easy for the motor to drive the rotating shaft and drive rod to rotate, and the drive rod in turn drives the hollow tube and grinding block to rotate, thereby realizing the grinding drive of the material.

[0013] As a preferred embodiment of this utility model, the longitudinal centerline of the drive rod is collinear with the longitudinal centerline of the hollow tube, and the drive rod has a square shape, while the hollow tube has an outer circle and inner square structure that matches the drive rod.

[0014] By adopting the above technical solution, the drive rod can stably drive the hollow tube to rotate, while allowing the hollow tube to move up and down on the drive rod without affecting the rotational transmission.

[0015] As a preferred embodiment of this utility model, the return material mechanism includes a cylinder, which is fixedly installed on the left side of the grinding box by a mounting block. An auger is installed on the central bearing of the inner bottom surface of the cylinder, and the auger bearing passes through the top center of the cylinder. The lower end of the right side wall of the cylinder is fixedly connected to the left end of the connecting pipe, and the right end of the connecting pipe is connected to the left side wall of the discharge pipe. A valve is provided on the connecting pipe. The upper end of the right side wall of the cylinder is fixedly connected to the left end of the return material pipe, and the right end of the return material pipe is fixedly connected to the upper end of the left side wall of the grinding box.

[0016] By adopting the above technical solution, after the valve on the connecting pipe is opened, the material can enter the cylinder through the connecting pipe, the auger rotates and conveys the material upward, and then it is sent back to the grinding box through the return pipe for further grinding, thus realizing the recycling and grinding of the material.

[0017] As a preferred embodiment of this utility model, the connecting pipe is inclined with the right side higher than the left side, and the return pipe is inclined with the left side higher than the right side.

[0018] By adopting the above technical solution, it is easier for materials to flow from the connecting pipe into the cylinder and from the return pipe into the grinding box under the action of gravity, thereby improving the smoothness of material circulation.

[0019] As a preferred embodiment of this utility model, the transmission mechanism includes a driving toothed pulley, which is fixedly installed on the surface of the rotating shaft and is connected to a driven toothed pulley via a toothed belt. The driven toothed pulley is fixedly installed on the surface of a reciprocating screw, and the top end of the reciprocating screw is connected to the bottom bearing of a fixed plate. The fixed plate is fixedly installed on the left side of the frame. The bottom end of the reciprocating screw is coaxially fixedly connected to the top end of the auger. A movable plate is sleeved on the surface of the reciprocating screw, and a hollow tube bearing passes through the movable plate. The rotation of the reciprocating screw is used for the reciprocating linear movement of the movable plate.

[0020] The above technical solution facilitates the rotation of the rotating shaft to drive the active toothed pulley to rotate, which in turn drives the driven toothed pulley and the reciprocating screw to rotate via the toothed belt. The rotation of the reciprocating screw causes the moving plate to move the hollow tube up and down, so that the grinding block rotates and moves up and down at the same time, improving the grinding effect. At the same time, the reciprocating screw also drives the auger to rotate, realizing the integration of transmission and saving power.

[0021] Compared with the prior art, the beneficial effects of this utility model are: the colloid grinding device can fully circulate and grind the material, which solves the problem of insufficient grinding of the material in a single cycle in the existing device, improves the sufficiency, effect and efficiency of colloid grinding, and improves the quality of colloid products;

[0022] 1. The rotating shaft is driven by a motor, which causes the drive rod to drive the hollow tube and grinding block to rotate synchronously, thereby achieving the grinding of materials;

[0023] 2. When the shaft rotates, the active toothed pulley, toothed belt and driven toothed pulley drive the reciprocating screw to rotate, so that the moving plate drives the hollow tube and grinding block to move back and forth in the vertical direction, ensuring that the grinding block rises and falls while rotating, increasing the contact range and force with the material, and improving the grinding effect and efficiency.

[0024] 3. The auger rotates synchronously with the reciprocating screw, which can circulate the material and achieve cyclic grinding of the material, thereby improving the thoroughness of grinding. Attached Figure Description

The top of the grinding block 6 is conical, and the grinding block 6 is adapted to the grinding box 1 to grind the material during the rotation of the grinding block 6. A drive mechanism for its rotation is connected to the top of the hollow tube 5. A return mechanism for material circulation is provided on the left side of the grinding box 1, and a transmission mechanism is connected to the top of the return mechanism. The transmission mechanism is connected to the drive mechanism and is used for the lifting and lowering movement of the hollow tube 5.

[0033] The drive mechanism includes a frame 7, which is fixedly installed on the top surface of the grinding box 1. A motor 8 is fixedly installed on the inner top surface of the frame 7. A rotating shaft 9 is keyed to the shaft end of the motor 8. A drive rod 10 is coaxially fixedly installed at the bottom end of the rotating shaft 9. The drive rod 10 extends movably into the interior of the hollow tube 5. The longitudinal axis of the drive rod 10 is collinear with the longitudinal axis of the hollow tube 5. The drive rod 10 has a square shape, and the hollow tube 5 has an outer circle and inner square structure that matches the drive rod 10.

[0034] The return material mechanism includes a cylinder 11, which is fixedly installed on the left side of the grinding box 1 by a mounting block. An auger 12 is installed on the central bearing of the inner bottom surface of the cylinder 11, and the auger 12 bearing passes through the top center of the cylinder 11. The lower end of the right side wall of the cylinder 11 is fixedly connected to the left end of the connecting pipe 13, and the right end of the connecting pipe 13 is connected to the left side wall of the discharge pipe 4. A valve is provided on the connecting pipe 13. The upper end of the right side wall of the cylinder 11 is fixedly connected to the left end of the return material pipe 14, and the right end of the return material pipe 14 is fixedly connected to the upper end of the left side wall of the grinding box 1. The connecting pipe 13 is inclined with the right side higher than the left side, and the return material pipe 14 is inclined with the left side higher than the right side.

[0035] The transmission mechanism includes a drive toothed pulley 15, which is fixedly mounted on the surface of the rotating shaft 9. The drive toothed pulley 15 is connected to the driven toothed pulley 17 via a toothed belt 16. The driven toothed pulley 17 is fixedly mounted on the surface of the reciprocating screw 18. The top end of the reciprocating screw 18 is connected to the bottom surface of the fixed plate 19 by a bearing. The fixed plate 19 is fixedly mounted on the left side of the frame 7. The bottom end of the reciprocating screw 18 is coaxially fixedly connected to the top end of the auger 12. A movable plate 20 is sleeved on the surface of the reciprocating screw 18. A hollow tube 5 bearing passes through the movable plate 20. The rotation of the reciprocating screw 18 is used for the reciprocating linear movement of the movable plate 20.

[0036] Working principle: When in use, the colloidal material to be ground is put into the grinding box 1 from the feed hopper 3, the motor 8 is started, the motor 8 drives the rotating shaft 9 to rotate, the rotating shaft 9 drives the drive rod 10 to rotate. Since the drive rod 10 is square and the hollow tube 5 has an outer circle and inner square structure, the drive rod 10 drives the hollow tube 5 and the grinding block 6 to rotate, thus grinding the material.

[0037] At the same time, the rotating shaft 9 drives the active toothed pulley 15 to rotate, which in turn drives the driven toothed pulley 17 to rotate through the toothed belt 16, thereby causing the reciprocating screw 18 to rotate. The rotation of the reciprocating screw 18 drives the moving plate 20 to move up and down reciprocally. The moving plate 20 drives the hollow tube 5 and the grinding block 6 to move up and down, ensuring that the grinding block 6 rotates while moving up and down, thus improving the grinding effect.

[0038] The rotation of the reciprocating screw 18 also drives the auger 12 to rotate. When it is necessary to circulate and grind the material, the valve on the connecting pipe 13 is opened. The material to be ground enters the cylinder 11 from the discharge pipe 4 through the connecting pipe 13. The auger 12 rotates and conveys the material upward. After the material reaches the upper part of the cylinder 11, it flows back into the grinding box 1 through the return pipe 14 and is ground again by the grinding blocks 6. This cycle is repeated to make the material grind more thoroughly.

[0039] After grinding is complete, close the valve on the connecting pipe 13 and open the discharge valve on the discharge pipe 4 to discharge the ground material from the discharge pipe 4.
