Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to an automatic cleaning mechanism for grinding beads. Background Technology

[0002] Grinding beads are a common grinding medium widely used in industries such as pharmaceuticals, chemicals, food, building materials, and ceramics. For example, in the pharmaceutical industry, grinding beads are used to prepare drug powders; in the food industry, grinding beads are used to make chocolate, dairy products, etc. After grinding, the surface of the grinding beads will absorb a lot of impurities, which will reduce the grinding efficiency, so they need to be cleaned.

[0003] Some existing cleaning equipment involves pouring grinding beads into the cleaning chamber for cleaning. The cleaning method involves a single stirring rod and its blades cleaning in one direction. During this process, it is difficult to clean the areas where the grinding beads accumulate, resulting in low cleaning efficiency. Utility Model Content

[0028] See Figure 1 , Figure 2 and Figure 4As shown, an automatic cleaning mechanism for grinding beads includes a housing 12 and a top cover 10 rotatably connected to the top of the housing 12. The top cover 10 has a water inlet 11 on its top. An upper base 21 is rotatably connected to the upper part of the inner side wall of the housing 12. A transmission mechanism 30 is provided below the upper base 21. The transmission mechanism 30 includes a gear 31 fixedly connected to the center of the bottom of the upper base 21. The outer ring of the gear 31 is meshed with four gears 32 arranged in a circular array. The sides of the four gears 32 away from the gear 31 are all meshed with the same internal gear ring 33. The internal gear ring 33 is slidably connected to the inner side wall of the housing 12. A transmission shaft 34 is fixedly connected to the inner ring of the gear 31. One side of the outer arc wall of the top cover 10 is rotatably connected to one side of the top of the housing 12 through the shaft. The top of the internal gear ring 33 does not contact the bottom of the upper base 21.

[0029] See Figure 2 As shown, an automatic cleaning mechanism for grinding beads has four longitudinally penetrating channels arranged in a circular array on the top of an upper chassis 21. The four channels are fan-shaped and each has a horizontal filter screen 22 installed inside. The top of the filter screen 22 is flush with the top of the upper chassis 21. Four gears 32 are fixedly connected to the bottom of the upper chassis 21. Five cleaning rollers 20 are fixedly connected to the top of the upper chassis 21. The five cleaning rollers 20 pass through and are rotatably connected to the upper chassis 21. The bottom of the five cleaning rollers 20 is fixedly connected to the top of the gears 31 and the four gears 32, respectively. Soft brushes are fixedly connected to the outer arc walls of the five cleaning rollers 20. The four gears 32 are not located at any point in the channels of the upper chassis 21.

[0030] See Figure 4 , Figure 5 and Figure 6 As shown, an automatic grinding bead cleaning mechanism is provided below the transmission mechanism 30, with a lower base 23 having the same structure as the upper base 21. The bottom of the internal gear ring 33 is fixedly connected to the top of the lower base 23. A horizontal support rod 52 is fixedly connected to the outer arc wall of the transmission shaft 34 near the lower base 23. A vertical spring telescopic rod 53 is fixedly connected to the end of the support rod 52 away from the transmission shaft 34. An inclined groove 54 is opened at the bottom of the spring telescopic rod 53 corresponding to the top of the lower base 23. The bottom of the spring telescopic rod 53 is slidably connected to the inclined groove 54. A small roller is fixedly connected to the bottom of the spring telescopic rod 53. The length of the inclined groove 54 is relatively short.

[0031] See Figure 2 and Figure 3As shown, an automatic cleaning mechanism for grinding beads has four diversion baffles 40 arranged in a circular array below the lower chassis 23. The four diversion baffles 40 correspond one-to-one with the four channels of the lower chassis 23. The bottom of each of the four diversion baffles 40 is fixedly connected to a support column 41. The bottom of the support column 41 is fixedly connected to the inner side wall of the bottom of the housing 12. The four support columns 41 are used to support the four diversion baffles 40 respectively.

[0032] See Figure 2 and Figure 3 As shown, an automatic grinding bead cleaning mechanism has a longitudinal channel two opened at the center of the lower chassis 23. The bottom end of the transmission shaft 34 is rotatably connected to the channel two. The bottom of the transmission shaft 34 is lower than the bottom of the lower chassis 23. The bottom of the transmission shaft 34 is rotatably connected to the bottom of the transmission shaft 34. A protective shell 51 is fitted around the outer ring of the motor 50. The side wall of the four diversion baffles 40 near the center of the lower chassis 23 is fixedly connected to the outer arc wall of the protective shell 51. The bottom of the motor 50 is fixedly connected to the bottom inner side wall of the protective shell 51. A water level alarm device is provided on the outside of the protective shell 51. When the sewage water level line at the bottom of the box 12 exceeds the water level alarm device, the machine will stop working and sound an alarm, thereby preventing sewage from flowing into the protective shell 51 and damaging the motor 50.

[0033] See Figure 2 As shown, an automatic cleaning mechanism for grinding beads is provided. A water outlet 24 is provided on one side wall at the bottom of the housing 12. A valve 25 is fixedly connected to the end of the water outlet 24 away from the housing 12. The bottom inner side wall of the housing 12 is inclined towards the water outlet 24 to facilitate the discharge of sewage.

[0034] Working principle:

[0035] Step 1: Open the top cover 10, first pour the grinding beads into the box 12, the grinding beads will then fall on the top of the upper base 21, then connect the water pipe to the water inlet 11, close the top cover 10, turn on the power and fill with water.

[0036] Step 2: The motor 50 drives the transmission shaft 34 to drive gear 1 31 to rotate counterclockwise. Gear 1 31 then drives four gears 2 32 to rotate clockwise in sync. The cleaning roller shaft 20 corresponding to gear 1 31 and the cleaning roller shaft 20 corresponding to the four gears 2 32 also rotate together to clean the grinding beads. The four gears 2 32 drive the internal gear ring 33 to rotate clockwise. The internal gear ring 33 drives the lower base 23 to rotate synchronously. At this time, the upper base 21 and the lower base 23 rotate in opposite directions. The wastewater generated during cleaning will flow from the top of the upper base 21 to the bottom of the lower base 23 through the filter screen 22.

[0037] Step 3: After cleaning, the motor 50 drives the transmission shaft 34 to rotate slowly clockwise. The upper chassis 21 rotates clockwise and the lower chassis 23 rotates counterclockwise. The support rod 52 and the spring telescopic rod 53 on the side wall of the transmission shaft 34 rotate together with the transmission shaft 34. When the spring telescopic rod 53 rotates clockwise into the inclined slide 54, the right-angle side of the inclined slide 54 will block the spring telescopic rod 53. At this time, the motor 50 stops working and the channel between the upper chassis 21 and the lower chassis 23 is connected. That is, at this time, the sewage will flow into the sewage collection tank below at the fastest speed.

[0038] Step 4: After the sewage flows out from the channel 1 of the lower chassis 23, it flows into the sewage collection tank at the bottom of the box 12 along the diversion baffle 40. When the sewage exceeds the water level alarm device on the outer arc wall of the protective shell 51, the motor 50 stops working. At this time, the valve 25 is opened to allow the sewage to flow out from the outlet 24.
