Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically a sealed pulverizer. Background Technology

[0002] Powdered raw materials, such as sugar powder, spice powder, and nut powder, are frequently used in food production and processing. For example, when producing sugar powder, large sugar particles need to be crushed into powder using a grinder. After crushing the large sugar particles, some sugar residue remains on the inner wall of the grinder. If not cleaned promptly, this residue will adhere even more firmly to the grinder's inner wall. Therefore, the grinder must be cleaned after each sugar powder production cycle, which is very troublesome, reduces worker efficiency, and increases worker workload. Furthermore, the current grinder's feed inlet is open; if not sealed, sugar powder will escape into the air, causing sugar powder to permeate the production workshop. Additionally, sugar powder frequently falls from below the grinder, easily breeding bacteria and causing contamination. Utility Model Content

[0003] The purpose of this invention is to provide a sealed pulverizer to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a sealed pulverizer, including a support frame, a housing mounted on the support frame, a drive shaft rotatably mounted on the housing, an active pulverizing disc mounted on the drive shaft, and several cleaning blocks on the side of the pulverizing disc. The cleaning blocks clean the inner wall of the housing and can scrape off residual sugar powder on the inner wall of the housing in real time, reducing manual cleaning operations and making it more convenient to use.

[0005] The inner wall of the housing is provided with several discharge holes. An inspection cover is rotatably installed on the outer surface of the housing. The inspection cover is fixedly connected to the housing by a locking component. A passive crushing disc is provided on the inner surface of the inspection cover. The inspection cover rotatably installed on the outer surface of the housing, together with the locking component, can be opened and closed quickly, which facilitates the maintenance and cleaning of the active crushing disc and passive crushing disc inside the housing by the staff.

[0006] The feeding hopper is connected to the middle of the inspection cover. A perforated plate is installed at the corner of the feeding hopper. The perforated plate is rotated and installed with a cover by fasteners. The cover seals the feeding hopper, which can ensure that the feeding hopper will not open during the crushing process, prevent sugar powder leakage and environmental pollution, and reduce sugar powder loss.

[0007] The discharge pipe is connected to the lower surface of the support, and a vacuum cleaner is connected to the side of the discharge pipe. The vacuum cleaner can better prevent the sugar powder from floating upwards and can collect the sugar powder in a concentrated manner to prevent it from falling into the environment.

[0008] Furthermore, a fixing frame is welded to the side of the bracket, and a motor is installed on the fixing frame. The motor is connected to the drive shaft through a belt drive module. Compared with gear drive, belt drive has the function of buffering and shock absorption, which can reduce the impact on the drive shaft when the motor starts and extend the service life of core components such as drive shaft and active crushing disc.

[0009] Furthermore, the locking component includes a socket and a U-shaped plate, which are welded to the housing and the inspection cover, respectively. A screw is fitted onto the socket, and a handle is screwed onto the screw. Tightening the handle presses against the U-shaped plate to lock the inspection cover to the housing. The operator only needs to turn the handle to push the screw against the U-shaped plate to lock the inspection cover. Tightening the handle in the opposite direction will loosen it. Compared with traditional bolt locking, no wrench or other tools are needed, and the passive and active pulverizing discs can be cleaned quickly.

[0010] Furthermore, a handle is welded to the upper surface of the cover. By rotating the cover using the handle, the hopper can be sealed. The cover can be rotated easily, making operation quick and improving work efficiency when feeding materials frequently.

[0011] Furthermore, the vacuum cleaner includes a housing and an exhaust fan installed inside the housing. The air inlet of the exhaust fan is connected to a filter element, and a suction pipe is connected to the discharge pipe at the lower part of the housing surface. The exhaust fan is connected to the discharge pipe through the suction pipe, which can suck the sugar powder dust generated during the discharge process into the housing, preventing the dust from spreading in the air and polluting the environment. The sucked-in dust is filtered by the filter element and remains in the housing, which can be periodically recycled and reused, reducing material waste.

[0012] Furthermore, the surface of the feeding hopper is provided with a clearing port, which is screwed with a sealing bolt. By unscrewing the sealing bolt, tools can be inserted through the clearing port to clear blockages, thus avoiding equipment downtime due to blockages and ensuring production continuity.

[0013] Furthermore, a connecting seat is provided on the side of the housing, and a bending plate is rotatably connected to the connecting seat. The bending plate is fixedly connected to the inspection cover to form a stable hinge structure, ensuring that the inspection cover rotates along a fixed trajectory when opening and closing, and that the inspection cover and the housing are precisely aligned.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) The motor drives the active crushing disc to rotate. The active crushing disc, together with the passive crushing disc, crushes large sugar particles. The cleaning block on the side of the active crushing disc can clean the inner wall of the machine casing. The inner wall of the machine casing is cleaner and less likely to have residual sugar powder, thus avoiding contamination of the product due to bacterial growth.

[0016] (2) Large sugar particles are fed into the machine casing through the feeding hopper. During the crushing process of large sugar particles, the hopper is blocked by rotating the cover. This can prevent sugar powder from floating out and avoid sugar powder from falling around the support, thus ensuring environmental hygiene and reducing bacterial growth.

[0017] (3) The blower extracts the sugar powder floating in the feed pipe through the suction pipe. The filter element prevents the sugar powder from entering the blower. The sugar powder falls into the box and can be collected to avoid sugar powder waste. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example:

[0026] Please see Figure 1-5 This utility model provides a technical solution: a sealed pulverizer, including a support 4, on which a shell 6 is installed. The lower part of the shell 6 is designed with an opening, and the support 4 is provided with a corresponding opening so that sugar powder can fall in.

[0027] A drive shaft 23 is rotatably mounted on the housing 6. An active crushing disc 19 is mounted on the drive shaft 23. Several cleaning blocks 21 are provided on the side of the crushing disc. The cleaning blocks 21 are close to but do not contact the inner wall of the housing 6. The cleaning blocks 21 clean the inner wall of the housing 6 to prevent excessive sugar powder residue from remaining inside the housing 6.

[0028] A maintenance cover 11 is rotatably mounted on the outer surface of the housing 6. The maintenance cover 11 is fixedly connected to the housing 6 by a locking member. A passive crushing disc 16 is provided on the inner surface of the maintenance cover 11. The maintenance cover 11 can be quickly opened and closed using the locking member, which facilitates cleaning of the passive crushing disc 16 and the active crushing disc 19.

[0029] Feeding hopper 7 is connected to the middle of inspection cover 11. A perforated plate 10 is installed at the corner of the feeding hopper 7. A sealing cover 8 is installed on the perforated plate 10 by fasteners and the sealing cover 8 blocks the feeding hopper 7.

[0030] The discharge pipe 12 is connected to the lower surface of the support 4. The inner wall of the cleaning machine shell 6 is provided with several discharge holes 22. After large sugar particles are crushed, they fall down from the discharge holes 22. A receiving bucket is placed below the discharge pipe 12 to collect the sugar powder. A vacuum cleaner is connected to the side of the discharge pipe 12 to prevent the sugar powder from floating out of the discharge pipe 12.

[0031] In this embodiment, as Figure 1 and Figure 2 As shown, a fixing frame 5 is welded to the side of the bracket 4. A motor 18 is installed on the fixing frame 5. The motor 18 is connected to the drive shaft 23 through a belt drive module 20. The belt drive module 20 includes a belt and two pulleys. The motor 18 drives the drive shaft 23 and the active crushing disc 19 to rotate through the belt and the two pulleys. The passive crushing disc 16 is close to the active crushing disc 19. The active crushing disc 19 cooperates with the passive crushing disc 16 to crush large sugar particles.

[0032] In this embodiment, as Figure 2 and Figure 3 As shown, the locking component includes a socket 17 and a U-shaped plate 15. The socket 17 and the U-shaped plate 15 are welded to the housing 6 and the inspection cover 11, respectively. A screw is sleeved on the socket 17, and a handle 14 is screwed onto the screw. When the handle 14 is turned, it moves along the screw. The screw is located in the U-shaped plate 15, so turning the handle 14 presses against the U-shaped plate 15. At this time, the inspection cover 11 is in close contact with the housing 6, achieving a sealed lock of the inspection cover 11. Turning the handle 14 in the opposite direction and separating the screw from the U-shaped plate 15 allows the inspection cover 11 to be opened quickly.

[0033] In this embodiment, as Figure 1 and Figure 5As shown, a handle 9 is welded to the upper surface of the cover 8. The cover 8 is turned by the handle 9 to block the feeding hopper 7. The cover 8 can be turned quickly by the handle 9, which is more convenient when frequently opening and closing the cover 8.

[0034] In this embodiment, as Figure 1 and Figure 2 As shown, the vacuum cleaner includes a housing 1 and an exhaust fan 2 installed inside the housing 1. The air inlet of the exhaust fan 2 is connected to a filter element 13. The lower part of the surface of the housing 1 is connected to the discharge pipe 12 and a suction pipe 3. The filter element 13 can effectively block sugar powder from entering the interior of the exhaust fan 2, prevent sugar powder from adhering to the blades of the exhaust fan 2 and affecting its operating efficiency, prevent exhaust fan 2 from malfunctioning, and extend the service life of the exhaust fan 2. The inner wall of the discharge pipe 12 is provided with an upwardly inclined baffle plate, which surrounds the suction pipe 3 and can prevent excessive sugar powder from being drawn out by the suction pipe 3.

[0035] In this embodiment, as Figure 1 As shown, the surface of the feeding hopper 7 is provided with a dredging port, and a sealing bolt 24 is screwed into the dredging port. When the feeding hopper 7 is blocked, the sealing bolt 24 can be unscrewed to see the blockage more directly, making it easier to dredge the hopper.

[0036] In this embodiment, as Figure 1 As shown, the side of the housing 6 is provided with a connecting seat 25, and a bending plate 26 is rotatably connected to the connecting seat 25. The bending plate 26 is fixedly connected to the inspection cover 11. A practical pin passes through the connecting seat 25 and the bending plate 26 to realize the rotatable installation of the inspection cover 11 and the housing 6.

[0037] Specifically, when in use, start the exhaust fan 2 and motor 18. Motor 18 drives the active crushing disc 19 to rotate, pouring large sugar granules into the feeding hopper 7. Rotate the cover 8 to block the feeding hopper 7. The active crushing disc 19 rotates in conjunction with the passive crushing disc 16 to crush the large sugar granules that fall into the machine casing 6.

[0038] After large sugar particles are crushed into sugar powder, the sugar powder falls from the discharge hole 22 into the discharge pipe 12. A receiving bucket is placed below the discharge pipe 12. The sugar powder falls into the receiving bucket and is collected. The sugar powder floating in the discharge pipe 12 is drawn into the box 1 by the suction pipe 3. The filter element 13 intercepts the sugar powder and concentrates the sugar powder into the box 1.

[0039] During the rotation of the active crushing disc 19, the cleaning block 21 rotates synchronously with the active crushing disc 19. The cleaning block 21 cleans the inner wall of the machine casing 6, and the cover 8 blocks the feeding hopper 7, so that the sugar powder inside the machine casing 6 will not float out of the hopper.

[0040] When the passive grinding disc 16 and the active grinding disc 19 need to be cleaned, turn the handle 14 to separate it from the U-shaped plate 15, and the inspection cover 11 can be opened. Figure 3As shown, the passive grinding disc 16 and the active grinding disc 19 can be cleaned quickly.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
