Description

Technical Field

[0001] The invention relates to the technical field of chemical processing, and in particular to a grinding device for processing chemical products. Background Art

[0002] The grinding device for chemical product processing is a device used to grind chemical raw materials or semi-finished products into smaller particles or finer powders.

[0003] Existing devices of this type have the problem of low efficiency. For example, a chemical raw material grinding device disclosed in Chinese Patent Publication No. "CN213000334U" uses a grinding column to grind chemical raw materials. However, the grinding column of the device can only cover a limited area, which makes the grinding efficiency of the device relatively low. At the same time, the grinding column and the grinding disk of the device are distributed up and down, and the chemical raw materials are located between the grinding column and the grinding disk. When in use, if the chemical raw materials are piled up too much, the thickness of the chemical raw materials between the grinding column and the grinding disk is too thick, then the grinding column of the device cannot contact the grinding disk, which will cause the device to be unable to grind in this case. Based on this, the present application proposes a grinding device for chemical product processing. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a grinding device for chemical product processing.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] The cleaning mechanism is composed of a sealing cover, a piston, a rack, a half gear, and a sealing chamber. The cleaning mechanism is used to remove residual chemical raw materials. The sealing cover is rotatably sealed and connected to the upper end of the crushing cylinder.

[0008] Preferably, a filter screen is provided in the feed port, the motor and the piston are fixedly connected to the upper surface of the sealing cover, there are two pulleys, one of which is fixedly connected to the output shaft of the motor, and the other is located below the center of the half gear and fixedly connected to the half gear, and the transmission belt cooperates with the two pulleys.

[0009] Preferably, a synchronization rod is fixedly connected to the rack, a planar thread is fixedly connected to the synchronization rod, the planar thread is rotatably connected to the lower end of the shell, and a limit plate is fixedly connected to the upper end of the shell.

[0010] Preferably, the output shaft of the motor is fixedly connected to the crushing barrel, a No. 1 spring rod is fixedly connected to the outer surface of the shell, the working grinding rod is arranged on the inner wall of the shell, and a plurality of quick-change grinding rods are arranged in the gap between the inner wall of the shell and the limit plate. The front end of the output rod of the No. 1 spring rod is tightly attached to the rear of the quick-change grinding rod, and a limit block is slidably provided at the lower end of the working grinding rod, and the lower end of the limit block is arranged in a plane thread, a clamping block is arranged in the limit block, and a clamping block spring is fixedly arranged between the clamping block and the limit block.

[0011] Preferably, a plurality of rotary valves are arranged in the crushing cylinder, a No. 2 spring rod is fixedly arranged on the upper end of the rotary valve, a sealing plate is arranged for the internal sliding seal of the rotary valve, and the output rod of the No. 2 spring rod is fixedly connected to the upper end of the sealing plate.

[0013] Preferably, an air pipe is provided on the piston, the air pipe is connected to the sealing chamber, a charging box is fixedly provided at the lower end of the shell, and a support foot is fixedly connected to the lower end of the shell located outside the charging box.

[0014] The present invention has the following beneficial effects:

[0015] 1. By setting the crushing cylinder and the grinding rod, the grinding space of the device during operation is increased, thereby increasing the contact area of ​​the device during grinding, thereby improving the grinding efficiency of the device.

[0016] 2. By setting the plane thread and the synchronization rod, when the device is working, the plane thread can be driven to rotate by the synchronization rod, and the rotation of the plane thread will change the position of the limit block. When the position of the limit block changes, the gap between the crushing cylinder and the grinding rod will also change. This allows the grinding rod to move back and forth when the device is working, and squeeze the chemical raw materials, thereby improving the crushing effect. At the same time, due to the existence of the squeezing action, the chemical raw materials can be squeezed and crushed, thereby allowing the device to avoid the problem of the thickness of the chemical raw materials being too thick to be ground.

[0017] 3. By setting up the quick-change grinding rod and the No. 1 spring rod, after the unusable working grinding rod is taken away, the quick-change grinding rod will be directly ejected from the outside to the working position, thereby improving the efficiency of the device when replacing the grinding rod.

[0018] 4. By setting the piston and the sealing chamber, the piston can supply air to the sealing chamber when the device is working. At the same time, when the crushing cylinder rotates, the sealing chamber can be opened to allow the compressed gas inside the sealing chamber to be ejected from the rotating valve, thereby allowing the residual chemical raw materials inside the device to be blown down from the inside of the shell to avoid the residue of chemical raw materials.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] Embodiment 1:

[0034] refer to Figure 1 and Figure 5 , Figure 8 A grinding device for chemical product processing includes a crushing mechanism and a cleaning mechanism. The crushing mechanism consists of a feed port 1, a shell 2, a motor 15, a pulley 16, a transmission belt 17, a working grinding rod 19, and a crushing cylinder 20. The crushing mechanism is used to grind chemical raw materials. A charging box 9 is fixedly provided at the lower end of the shell 2. The lower end of the shell 2 is located outside the charging box 9 and is fixedly connected with a support foot 21.

[0035] A plurality of rotary valves 23 are provided in the crushing cylinder 20 , a second spring rod 25 is fixedly provided at the upper end of the rotary valve 23 , a sealing plate 26 is provided for the internal sliding seal of the rotary valve 23 , and an output rod of the second spring rod 25 is fixedly connected to the upper end of the sealing plate 26 .

[0036] A filter screen 4 is provided in the feed port 1, and there are two pulleys 16, one of which is fixedly connected to the output shaft of the motor 15, and the other pulley 16 is located below the center of the half gear 32 and fixedly connected to the half gear 32, and the transmission belt 17 cooperates with the two pulleys 16, and the output shaft of the motor 15 is fixedly connected to the crushing drum 20.

[0037] The working grinding rod 19 is arranged on the inner wall of the shell 2, and a limit block 29 is slidably arranged at the lower end of the working grinding rod 19, a clamping block 30 is arranged inside the limit block 29, a clamping block spring 31 is fixedly arranged between the clamping block 30 and the limit block 29, and the lower end of the limit block 29 is arranged in the plane thread 27.

[0038] In this embodiment, the edge of the filter screen 4 is made of rubber and needs to be removed from the feed port 1 when in use. Then, chemical raw materials are poured into the feed port 1, and then the motor 15 is turned on to start grinding. In this device, springs that can be used for resetting are provided in the piston 8, the No. 1 spring rod 6, and the No. 2 spring rod 25.

[0039] Furthermore, the rotation of the motor 15 will drive the rotation of the crushing barrel 20. After the crushing barrel 20 rotates, the chemical raw materials between the crushing barrel 20 and the inner wall of the shell 2 will be crushed by the rotating crushing barrel 20 and the working grinding rod 19. During this period, the rotation of the motor 15 will also drive the pulley 16 to rotate, and then the transmission belt 17 will transmit the power to another pulley 16. The other pulley 16 will drive the half gear 32 to rotate, and then the half gear 32 will mesh with the rack 28, which will allow the piston 8 to suck in the outside air and then enter the sealed chamber 22 to complete the air storage. At the same time, the movement of the rack 28 will drive the movement of the synchronization rod 5. Since the synchronization rod 5 is fixedly connected to the plane thread 27, when the synchronization rod 5 moves, the plane thread 27 will also rotate.

[0040] Furthermore, the plane thread 27 is usually used on the three-jaw chuck of the machine tool. When the plane thread rotates, the engaging claw will move inward or outward. This is a mature existing technology. In the present device, the plane thread 27 will engage with the lower end of the limit block 29. When the plane thread 27 rotates driven by the synchronization rod 5, the limit block 29 will move forward or backward. Since a spring for resetting is provided in the piston 8, the synchronization rod 5 will also be reset. When the synchronization rod 5 is reset, the plane thread 27 will also be reset with the synchronization rod 5. Since this resetting and rotation movement is continuous, it can allow the limit block 29 to continuously reciprocate and squeeze, so that the chemical raw materials in the present device will be crushed by the working grinding rod 19 while being rotated and crushed.

[0041] Embodiment 2: Different from Embodiment 1, reference Figure 5 , this embodiment also has the following further contents:

[0042] The upper end of the shell 2 is fixedly connected to a limit plate 24, and a plurality of quick-change grinding rods 18 are arranged in the gap between the inner wall of the shell 2 and the limit plate 24. A second fixing plate 14 and a first fixing plate 13 are fixedly connected to the limit plate 24. A fixing ring 3 is fixedly connected to the upper ends of the first and second fixing plates 13 and 14. A plurality of clamping plates 10 are arranged between the first and second fixing plates 13 and 14. A guide ring 12 is slidably arranged on the clamping plates 10. A tension spring 11 is fixedly arranged between every two clamping plates 10. The crushing barrel 20 is rotatably connected to the inside of the shell 2, and a No. 1 spring rod 6 is fixedly connected to the outer surface of the shell 2. The front end of the output rod of the No. 1 spring rod 6 is tightly attached to the rear of the quick-change grinding rod 18.

[0043] In this embodiment, when the working grinding rod 19 cannot work due to wear, the user can pull out the working grinding rod 19 directly from the top, and then the quick-change grinding rod 18 will be pushed forward by the No. 1 spring rod 6, so that the side wall of the quick-change grinding rod 18 cooperates with the block 30, and then the position of the quick-change grinding rod 18 is restricted by the block 30, completing the quick replacement.

[0044] Furthermore, there is an inclined surface on the card block 30, and there are several card block springs 31 inside the limit block 29. When the working grinding rod 19 is pulled out, the tension spring 11 will pull the multiple clamps 10, so that the multiple clamps 10 press the multiple quick-change grinding rods 18, forming a situation where the multiple quick-change grinding rods 18 fit each other, and the tension spring 11 can overcome the spring force of the No. 1 spring rod 6. When the working grinding rod 19 is pulled out, there will always be a quick-change grinding rod 18 located such as Figure 5 position, and then the quick-change grinding rod 18 is pushed out to the position of the working grinding rod 19 under the action of the No. 1 spring rod 6, thereby completing the quick change of the grinding rod.

[0045] Embodiment 3: Different from Embodiment 1 and Embodiment 2, reference Figure 1-7 The cleaning mechanism is composed of a sealing cover 7, a piston 8, a rack 28, a half gear 32, and a sealing chamber 22. The cleaning mechanism is used to remove residual chemical raw materials. The sealing cover 7 is rotatably sealed and connected to the upper end of the crushing cylinder 20. An air pipe 33 is provided on the piston 37, and the air pipe 33 is connected to the sealing chamber 22. The motor 15 and the piston 8 are fixedly connected to the upper surface of the sealing cover 7. The rack 28 is fixedly connected to a synchronization rod 5, and the synchronization rod 5 is fixedly connected to a plane thread 27, and the plane thread 27 is rotatably connected to the lower end of the shell 2.

[0046] In this embodiment, the rotation of the motor 15 causes the piston 8 to inflate the sealed chamber 22, and at the same time, the crushing cylinder 20 is rotatably sealed and connected with the sealing cover 7. When the motor 15 is started, the crushing cylinder 20 rotates. Figure 7 The sealing plate 26 is slidably connected to the rotary valve 23. Under the action of the second spring rod 25, the sealing plate 26 will Figure 7 position, at which time it is in a state of sealing the rotary valve 23, and the gas provided by the piston 8 cannot be ejected. When the rotation speed of the crushing cylinder 20 reaches a certain value, the weight of the sealing plate 26 itself can overcome the force of the second spring rod 25, and then can slide into the interior of the rotary valve 23, allowing the rotary valve 23 to open. At this time, the compressed air in the sealing chamber 22 will blow to the inner wall of the shell 2, blowing off the residual chemical raw materials on the inner wall, and then the air will be discharged by the filter screen 4, and the chemical raw materials will be retained in the shell 2.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
