Description

Technical Field

[0002] Chemical raw material grinding equipment refers to a type of ultrafine grinding equipment consisting of a stationary cylinder filled with grinding media and a rotary agitator. There are various types of agitators, including shaft type, disc type, perforated disc type, cylindrical type, ring type, spiral type, etc. The grinding action of the stirred mill mainly occurs between the grinding media and the material. It can be used to process most non-metallic minerals, such as talc, heavy calcium carbonate, kaolin, graphite and bentonite, and can also be used to prepare various colored pigments.

[0003] There are many grinding equipment on the market today, but most of them can only screen out chemical raw materials of one particle size. If multiple particle sizes are required, the screen needs to be replaced and the grinding and screening need to be repeated, which increases the workload of the staff. In addition, the screen is prone to clogging during the screening process, which reduces work efficiency. Furthermore, a large amount of raw material will be stored in the screen frame during the screening process. Once the screen frame is full of raw material, the device needs to be opened to clean out the raw material before the screening work can continue.

[0004] Therefore, it is necessary to provide a new, high-efficiency chemical raw material grinding and screening equipment to solve the above-mentioned technical problems. Utility Model Content

A screw is fixedly connected to the top of each insert, and a nut is threaded onto the outer wall of the screw. A caster is fixedly connected to the bottom of each insert.

[0009] Preferably, the vibration structure is fixed to the inner wall of the outer shell in three equidistant layers. The vibration structure includes a vibration motor, a placement frame, a spring, and a limiting block. The limiting block is fixed to the inner wall of the main structure, the placement frame is mounted on the limiting block, the spring is supported on the side wall at the bottom of the placement frame, and the vibration motor is fixed to the top surface of the placement frame.

[0010] Preferably, the screen is divided into three layers: upper, middle, and lower, and the size of the screen mesh gradually decreases from top to bottom.

[0011] Preferably, the placement rack is supported inside the limiting block by the spring, and the placement rack and the limiting block are slidably connected.

[0015] Compared with related technologies, the high-efficiency chemical raw material grinding and screening equipment provided by this utility model has the following beneficial effects: This utility model provides a high-efficiency chemical raw material grinding and screening equipment. By setting up the screening structure, particles generated during grinding can be screened. The screening structure body has three sets, with the mesh size gradually decreasing from top to bottom. The raw material screened by the bottom screening structure falls into the material bin. By setting up three sets of screening structures with different sizes, raw materials of various particle sizes can be screened uniformly. The vibration motor can vibrate the placement frame and the screening structure together. A drive structure is installed in the center of the main structure. By connecting the drive structure to an external power source, the sweeping bar can be driven to rotate against the screen. As the sweeping bar rotates, it first agitates the raw material on the inner side of the screen, sweeping materials larger than the mesh size to the outer side of the screen, thus allowing the raw material to fall from the gap between the screen and the outer frame into the discharge structure. The material is stored in the mesh bin. As the screening structure vibrates, the mesh bin vibrates, causing the raw material to undergo secondary screening. The bottom surface of the mesh bin is equipped with baffles that gradually increase in size from the inside to the outside. These baffles restrict the movement of the material, thereby further enhancing the screening effect of the mesh bin and preventing small pieces of material from being mixed in. This not only reduces the workload of the workers but also improves the production efficiency and continuous production of chemical raw materials. Attached Figure Description

The outer frame 71 is mounted inside the vibrating structure 6, and the screen 72 is fixed to the connecting block 73. On the inner side wall of the lower end of the outer frame 71, and with one end of the driving structure 5 penetrating through the center of the screen 72, a material hopper 9 is fixed at the inner opening of the outer frame 71; a discharge structure 4 is fixed to the bottom end of the outer frame 71, and the discharge structure 4 includes a discharge port 41, a receiving groove 42, a mesh bin 43, and a baffle 44. The receiving groove 42 is fixed to the bottom end of the outer frame 71 and the bottom surface of the edge of the screen 72. The discharge port 41 is located on the side wall of the main structure 2, and the mesh bin... 43 is fixed to one end of the bottom surface of the receiving trough 42. A guide plate 8 is provided directly below the mesh bin 43, and the guide plate 8 is connected to the collecting hopper 9, with the same slope angle. The bottom end of the mesh bin 43 is connected to the inner wall of the main structure 2 through the positioning plate 11, and the size of the mesh of the mesh bin 43 corresponds to the size of the mesh of the screen 72 in the same layer. The baffle 44 is fixed to the bottom surface inside the mesh bin 43; the driving structure 5 is fixed inside the main structure 2. The drive structure 5 includes a drive motor 51, a drive rod 52, a fixed cylinder 53, a sweeping bar 54, and a shock-absorbing pad 55. The drive motor 51 is installed at the center of the bottom surface inside the housing 21. The drive rod 52 is installed at the top of the drive motor 51 and passes through the center of the screen 72. The fixed cylinder 53 is fixed to the side wall of the drive rod 52. The sweeping bar 54 is fixed to the side wall of the fixed cylinder 53. The shock-absorbing pad 55 is fixed between the connection point of the screen 72 and the fixed cylinder 53.

[0020] In the specific implementation process, such as Figure 1 and Figure 2 As shown, the main structure 2 includes an outer shell 21, a material bin 22, and a bottom plate 23. The grinding tank 1 is fixed at the center of the top surface of the outer shell 21. The material bin 22 is located inside the bottom end of the outer shell 21. The bottom plate 23 is fixed to the bottom end of the outer shell 21. This facilitates the protection and support of the internal screening components through the outer shell 21.

[0021] In the specific implementation process, such as Figure 1 and Figure 2As shown, the movable structure 3 includes a nut 31, a screw 32, a caster wheel 33, and a plug 34. The bottom plate 23 has through holes at all four corners, and the inner walls of the through holes are fitted with plugs 34. The top of each plug 34 is fixedly connected to a screw 32, and the outer wall of each screw 32 is threaded with a nut 31. The bottom of each plug 34 is fixedly connected to a caster wheel 33, which facilitates the adjustment of the device's position.

[0022] In the specific implementation process, such as Figure 2 and Figure 7 As shown, the vibration structure 6 is fixed to the inner wall of the main structure 2 in three equidistant layers. The vibration structure 6 includes a vibration motor 61, a placement frame 62, a spring 63, and a limiting block 64. The limiting block 64 is fixed to the inner wall of the main structure 2. The placement frame 62 is installed on the limiting block 64. The spring 63 supports the side wall at the bottom of the placement frame 62. The vibration motor 61 is fixed to the top surface of the placement frame 62. The placement frame 62 is supported inside the limiting block 64 by the spring 63, and the placement frame 62 is slidably connected to the limiting tube. This allows the vibration motor 61 to vibrate the placement frame 62, thereby driving the outer frame 71 and the screen 72 to vibrate, thus achieving the purpose of screening by the screen 72.

[0023] In the specific implementation process, such as Figure 2 , Figure 3 and Figure 5 As shown, the screen 72 is divided into three layers: upper, middle, and lower, and the mesh size of the screen 72 gradually decreases from top to bottom. There is a certain distance between the screen 72 and the outer frame 71, and the receiving trough 42 is fixed to the bottom surface of the outer frame 71 and the edge of the screen 72. The opening width of the receiving trough 42 is greater than the length of the connecting block 73, and the groove on the inner side of the receiving trough 42 has a slope. This allows the three layers of screen 72 to separate raw materials of different particle sizes, and the screened raw materials can be collected through the receiving trough 42.

[0024] In the specific implementation process, such as Figure 2 , Figure 3 , Figure 5 and Figure 7As shown, each layer of the screen 72 is equipped with a corresponding sweeping bar 54, and the length of the sweeping bar 54 corresponds to the radius of the screen 72. One end of the sweeping bar 54 is arc-shaped, and the bottom end of the rubber sweeping bar 54 abuts against the surface of the screen 72. The outer side of the screen 72 has a certain slope, and one end of the sweeping bar 54 also has a corresponding slope to the slope of the screen 72. This facilitates the sweeping bar 54 to clean the material on the screen 72 by being driven by the drive rod 52.

[0025] The working principle of the high-efficiency chemical raw material grinding and screening equipment provided by this utility model is as follows: In use, first connect all electronic components in the device to an external power source. After the grinding tank 1 is connected to the external power source, the chemical raw materials are cut and ground. Guided by the hopper 9, the cut and ground chemical raw materials fall onto the uppermost screen 72 inside the outer casing 21. At this time, the vibration motor (model "MVE-MICRO vibration motor") vibrates the placement frame 62, thereby driving the outer frame 71 and the screen 72 to vibrate synchronously, screening the raw materials. Simultaneously, after the motor is connected to the power source, it drives the drive rod 52 to rotate, causing the fixed cylinder 53 to drive the sweeping bars 54 to rotate on the screen 72. The rotation of the sweeping bars 54 agitates the raw materials accumulated on the screen 72 that have not been screened out, and also cleans materials stuck in the mesh. This allows the raw materials to diffuse outwards under the guidance of the sweeping bars 54, pushing materials larger than the mesh size through the gap between the screen 72 and the outer frame 71 to the designated area. The raw materials are discharged into the receiving trough 42 and then into the mesh bin 53. The vibration of the screen 72 and the outer frame 71 is transmitted to the mesh bin 43 through the receiving trough 42, causing the mesh bin 53 to vibrate synchronously. This performs secondary screening of the raw materials stored in the mesh bin 53. The secondary screened raw materials are then guided into the next layer by the guide plate 8 directly below. After the mesh bin 43 is full of raw materials, the valve of the discharge port 41 is opened to discharge them, thus preventing the raw materials from accumulating on the screen 72. This allows the equipment to classify and collect chemical raw materials of different particle sizes during the screening process, facilitating the continuous screening operation of the device. Furthermore, the universal wheels 33 can drive the device to move, allowing the entire device to be moved and transported freely when idle. After removing the nut 31, the damaged universal wheels 33 can be disassembled and replaced.

[0026] Compared with related technologies, the high-efficiency chemical raw material grinding and screening equipment provided by this utility model has the following beneficial effects: This utility model provides a high-efficiency chemical raw material grinding and screening equipment. By setting the screening structure 7, particles generated during grinding can be screened. The screening structure 7 has three sets, with the mesh size gradually decreasing from top to bottom. The raw material screened by the bottom screening structure 7 falls into the material bin 22. By setting three sets of screening structures 7 with different sizes, raw materials of various particle sizes can be screened uniformly. The vibration motor 61 can vibrate the placement frame 62 and the screening structure 7 together. Furthermore, by installing the drive structure 5 in the central position inside the main structure 2, and connecting the drive structure to an external power source, the sweeping bar can be driven to rotate against the screen. As the sweeping bar rotates, it first... The material inside the screen 72 is agitated, and materials larger than the mesh size are swept to the outside of the screen 72. This allows the material to fall from the gap between the screen 72 and the outer frame 71 into the discharge structure 4, where it is stored in the mesh bin 43. As the screening structure 7 vibrates, the mesh bin 43 vibrates, causing the material to undergo secondary screening. Furthermore, the bottom surface of the mesh bin 43 is provided with baffles 44 that gradually increase in size from the inside to the outside. These baffles 44 restrict the movement of the material, further enhancing the screening effect of the mesh bin 43 and preventing small pieces of material from being mixed in. This not only reduces the workload of the workers but also improves the production efficiency and continuous production of chemical raw materials.
