Description

Technical Field

[0001] This utility model relates to the field of sand mill technology, and in particular to a self-cleaning sand mill. Background Technology

[0002] The sand mill is a wet ultrafine grinding and pulverizing equipment developed from the ball mill. In the industry, it is also often referred to as a grinding mill. Its early prototype was the ultrafine stirred mill, which completed the wet grinding of fine particles by adding a large amount of grinding media into the stirring cylinder. However, this method still has certain drawbacks, such as slow stirring speed and low grinding efficiency. With the continuous improvement of market requirements, the sand mill is also constantly being updated and has gradually developed into one of the indispensable pieces of equipment in the modern powder industry.

[0003] Chinese patent discloses a sand mill (authorization announcement number CN205765443U). This patented technology adopts a pressing rod device, which can press hard during grinding, solving the problem of unstable grinding wheels in existing sand mills, making the material smoother. A heat dissipation cover is installed behind the motor, which can effectively solve the problem of motor overheating. A protective cover is installed to prevent grinding debris from flying around and injuring people, making the equipment safer. The device is easy to operate and has a very good effect.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: During the use of existing sand mills, a large amount of grinding media residue is caused when the grinding head grinds the material, resulting in blockage or partial blockage of the grinding chamber inside the sand mill. This affects the full contact and collision between the grinding media and the material, which not only reduces grinding efficiency but also makes cleaning difficult and reduces the service life of the equipment. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the grinding media generated during the use of sand mill cannot be collected, which leads to cleaning difficulties and affects the service life of the equipment. Therefore, we propose a self-cleaning sand mill.

[0006] To achieve the above objectives, this application adopts the following technical solution: a self-cleaning sand mill, comprising a body, a handle fixed to one side of the body, a cylinder installed at the bottom of the body, a sand milling roller installed at the bottom of the cylinder, a control key on the top of the body, a dust extraction fan installed inside the cylinder, a grinding head installed inside the sand milling roller, a dust extraction pipe fixed to the outer surface of the sand milling roller, a collection box installed at one end of the dust extraction pipe, first housings fixed to both sides of the dust extraction pipe, second housings fixed to both sides of the collection box, sliding rods slidably connected to both sides inside the second housing, a circular plate fixed to one end of the sliding rod, a movable plate fixed to the other end of the sliding rod, a locking block fixed to the top of the movable plate, and slots for sliding connection with the locking blocks on both sides of the first housing.

[0007] Preferably, both sides inside the second housing are fixed with fixing rods, and the surface of the movable plate is provided with a through groove for sliding connection with the fixing rods.

[0008] Preferably, springs are fixed on both sides inside the second housing, and the other end of the springs is fixed to the movable plate.

[0009] Preferably, the diameter of the slide bar located outside the second housing is larger than the diameter of the card block inserted into the card slot.

[0010] Preferably, a connecting plate is fixed to one end of the collection box near the dust collection pipe, and a connecting groove is provided at one end of the dust collection pipe for insertion with the connecting plate.

[0011] Preferably, the surface of the dust collection pipe has multiple ventilation openings, and a filter screen is installed inside each ventilation opening.

[0012] Preferably, a water tank is installed on one side of the vacuuming pipe, a connecting pipe is provided on one side of the water tank and extends into the interior of the vacuuming pipe, an annular pipe is fixed to the other end of the connecting pipe, multiple nozzles are provided at the bottom of the annular pipe, and a water pump is installed on the top of the water tank.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] In this invention, by pressing the circular plate to push the slide bar towards the inside of the second housing, the moving plate causes the locking block to disengage from the inside of the slot, releasing the fixation on the first housing. This allows the dust collection pipe to be separated from the collection box, making it easier to access the inside of the dust collection pipe and the collection box. This enables a more thorough removal of residual abrasive media and materials, significantly shortening cleaning time, improving cleaning efficiency, and extending the equipment's lifespan.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] Reference Figure 1-Figure 5As shown, this utility model provides a technical solution: a self-cleaning sander, including a body 1, a handle 2 fixed to one side of the body 1, a cylinder 3 installed at the bottom of the body 1, a sanding roller 4 installed at the bottom of the cylinder 3, a control key 5 on the top of the body 1, a dust extraction fan 6 installed inside the cylinder 3, a grinding head 7 installed inside the sanding roller 4, a dust extraction pipe 8 fixed to the outer surface of the sanding roller 4, a collection box 9 installed at one end of the dust extraction pipe 8, first housings 10 fixed to both sides of the dust extraction pipe 8, second housings 11 fixed to both sides of the collection box 9, and sliding rods 12 slidably connected to both sides inside the second housings 11, with one end of the sliding rods 12 fixed to... The device has a circular plate 13, and a movable plate 14 is fixed to the other end of the slide rod 12. A locking block 15 is fixed to the top of the movable plate 14. Both sides of the first housing 10 are provided with locking grooves 16 that are slidably connected with the locking blocks 15. By pressing the circular plate 13, the slide rod 12 is pushed to move inward toward the second housing 11, causing the movable plate 14 to drive the locking blocks 15 out of the inside of the locking grooves 16, thus releasing the fixation on the first housing 10. This allows the vacuum pipe 8 to be separated from the collection box 9, making it easier to access the inside of the vacuum pipe 8 and the collection box 9. This enables a more thorough removal of residual grinding media and materials, significantly shortening the cleaning time, improving cleaning efficiency, and extending the equipment life.

[0023] Reference Figure 4 As shown in this embodiment: both sides of the interior of the second housing 11 are fixed with fixing rods 17, and the surface of the movable plate 14 is provided with a through groove 18 for sliding connection with the fixing rods 17. By setting the structure of fixing rods 17 and through groove 18, the movement trajectory of the movable plate 14 can be restricted to avoid tilting.

[0024] Reference Figure 4 As shown in this embodiment: springs 19 are fixed on both sides inside the second housing 11. The other end of the spring 19 is fixed to the moving plate 14. By setting the spring 19, when it is necessary to fix the dust suction pipe 8 and the collection box 9, the second housing 11 is reset, and the spring force of the spring 19 is used to push the moving plate 14 to drive the card block 15 to insert into the card slot 16.

[0025] Reference Figure 4 As shown, in this embodiment, the diameter of the slide bar 12 outside the second housing 11 is larger than the diameter of the card block 15 inserted into the card slot 16. By designing the diameter of the slide bar 12 outside the second housing 11 to be larger than the diameter of the card block 15 inserted into the card slot 16, it can be ensured that the moving distance of the moving plate 14 can completely disengage the card block 15 from the inside of the card slot 16.

[0026] Reference Figure 3As shown in this embodiment: a connecting plate 20 is fixed at one end of the collection box 9 near the suction pipe 8, and a connecting groove 21 is provided at one end of the suction pipe 8 for use in conjunction with the connecting plate 20. By setting the structure of the connecting plate 20 and the connecting groove 21, the stability of the connection between the suction pipe 8 and the collection box 9 can be improved.

[0027] Reference Figure 3 As shown in this embodiment: the surface of the vacuum pipe 8 is provided with multiple ventilation openings 22, and the inside of the ventilation openings 22 is provided with a filter screen. By setting the ventilation openings 22 and using them in conjunction with the filter screen, the vacuum airflow can enter the collection box 9 more smoothly, and can effectively filter out dust and other impurities that enter the collection box 9, thus preventing large particles from entering the vacuum pipe 8 and causing blockage of the vacuum pipe 8.

[0028] Reference Figure 2 and Figure 5 As shown in this embodiment: a water tank 23 is installed on one side of the dust collection pipe 8, a connecting pipe 24 is provided on one side of the water tank 23 and extends into the interior of the dust collection pipe 8, and an annular pipe 25 is fixed to the other end of the connecting pipe 24. Multiple nozzles are provided at the bottom of the annular pipe 25, and a water pump 26 is installed on the top of the water tank 23. By setting up the structure of the water tank 23, the connecting pipe 24, the annular pipe 25 and the water pump 26, and using them in conjunction with the nozzles, the heat generated by the sanding roller 4 and the grinding media can be removed, preventing the equipment from overheating and being damaged.

[0029] The specific operating steps for this self-cleaning sand mill are as follows:

[0030] 1. By pressing the circular plate 13, the sliding rod 12 is pushed towards the inside of the second housing 11, causing the moving plate 14 to drive the locking block 15 out of the inside of the locking slot 16, releasing the fixation on the first housing 10, thereby separating the vacuum pipe 8 from the collection box 9, making it easier to access the inside of the vacuum pipe 8 and the collection box 9, thus enabling more thorough removal of residual grinding media and materials. During the movement of the moving plate 14, the fixing rod 17 and the through groove 18 are used to assist in restricting the path.

[0031] 2. When it is necessary to fix the vacuum pipe 8 and the collection box 9, the second housing 11 is reset, and the spring force of the spring 19 is used to push the moving plate 14 to drive the locking block 15 into the slot 16.

[0032] Third, when the equipment overheats, the water pump 26 is started to deliver water from the water tank 23 to the inside of the annular pipe 25 through the connecting pipe 24, and in conjunction with the nozzle, to cool the inside of the sand grinding roller 4 and the grinding head 7, so as to ensure that the machine can automatically stop in abnormal conditions and protect the equipment from damage.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
