Description

Technical Field

[0001] This utility model relates to the field of citric acid production technology, and in particular to a centrifuge cleaning device. Background Technology

[0002] In the production of calcium citrate, centrifuges are often used to separate solids and liquids. Because calcium citrate particles are small, a flatbed centrifuge is used to separate them batch by batch.

[0003] When the centrifuge is working, the centrifuge rotor rotates rapidly under the drive of the pulley. Citric acid liquid enters through the feed inlet. Under the action of strong centrifugal force, the liquid is thrown through the filter cloth to the outer layer and discharged from the drain outlet. The solid calcium citrate adheres to the filter cloth. After the solid calcium citrate on the filter cloth reaches a certain thickness, the feed is turned off and the water inlet is turned on for washing. After washing, the centrifugation continues. After centrifugation, the scraper begins to scrape off the solid calcium citrate layer by layer, which enters the calcium citrate residue collection bin for the next process. In order to protect the scraper from damaging the filter cloth, a 6-10 mm calcium citrate filter layer must be left. The centrifuged calcium citrate filter layer is as hard as stone. In order to ensure the next batch of feed, the calcium citrate on the filter cloth must be cleaned off. The current method is to manually scrape it gently with a shovel, while also being careful not to tear the filter cloth. The operation is very difficult. Under normal circumstances, feeding takes 15 minutes, spinning takes 5 minutes, and scraping with a scraper takes 10 minutes to complete the process. However, cleaning the remaining 6-10 millimeters takes 1.5 hours, which is extremely time-consuming and seriously affects production efficiency.

[0004] Therefore, there is an urgent need for a centrifuge cleaning device that can quickly and easily remove the remaining 6-10 mm of calcium citrate, thereby improving work efficiency. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a centrifuge cleaning device.

[0006] This utility model is achieved through the following technical solution: a centrifuge cleaning device is provided, including a centrifuge body, a cleaning mechanism installed on the stator of the centrifuge body, and an adjustment mechanism for adjusting the position of the cleaning mechanism; the cleaning mechanism includes a cleaning part extending between the stator and the rotor for striking the rotor and a driving part for driving the cleaning part to move.

[0007] Preferably, the driving unit is a cylinder, the cylinder body is mounted on the stator via a connecting plate, and the piston rod of the cylinder passes through the stator and can extend between the stator and the rotor.

[0008] Preferably, the cleaning part is a hammer mounted on the cylinder piston rod.

[0009] Preferably, the striking hammer is a rubber hammer to avoid damaging the rotor.

[0010] Preferably, when the cylinder position is adjusted by the adjusting mechanism so that the cylinder piston rod is fully extended, the stroke of the striking hammer is 2-3 mm greater than the distance between the initial position of the striking hammer and the rotor. This ensures that the cylinder extension and retraction generates impact force without damaging the rotor, allowing the residual calcium citrate layer inside to easily detach under external impact, thereby achieving the function of cleaning calcium citrate.

[0011] Preferably, a mounting hole is provided on the stator, and the piston rod of the cylinder extends through the mounting hole to the space between the stator and the rotor.

[0012] Preferably, the adjusting mechanism is a self-locking hand-cranked screw slide, which includes fixed plates at both ends, a slide rail installed between the two fixed plates, and a screw parallel to the slide rail and rotatably connected between the two fixed plates. The slide is mounted on the screw and the slide rail. One end of the screw is fixed to the crank handle, and a locking part is installed at that end of the screw. The locking part is secured to the screw by a tightening bolt, preventing it from rotating.

[0013] Preferably, the connecting plate is fixed to the slide table, and guide rods are respectively installed on the stators located on the upper and lower sides of the cylinder body, with the guide rods penetrating the connecting plate. The guide rods guide the movement of the cylinder, stabilizing and adjusting the cylinder position. The slide table moves the connecting plate by hand-cranking the handle, thereby moving the cylinder. Preferably, the cleaning mechanism is arranged in three groups from top to bottom, with an adjustment mechanism installed between every two groups of cleaning mechanisms. Simultaneous rotation of two adjustment mechanisms by both hands moves all three cleaning mechanisms synchronously, facilitating the installation and debugging of this invention. The positions of all three cleaning mechanisms can be adjusted at once, eliminating the need to adjust each mechanism individually. This convenient operation saves time and effort, improving the efficiency of installation and debugging.

[0014] The beneficial effects of this utility model are as follows: 1. This invention significantly reduces the difficulty of cleaning and effectively avoids the problem of damage to the filter cloth caused by cleaning from the inner layer. This invention can clean the remaining calcium citrate quickly and easily without damaging the filter cloth, taking only 15-20 minutes, which greatly shortens the cleaning time and improves work efficiency.

[0015] 2. The position of the three cleaning mechanisms can be adjusted at once by adjusting the mechanism, without the need to adjust the position of each cleaning mechanism individually. This makes the operation convenient, saves time and effort, and improves the efficiency of installation and debugging of this utility model. Attached Figure Description

[0017] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0018] like Figure 1-3 As shown, this utility model includes a centrifuge body, a cleaning mechanism installed on the stator 1 of the centrifuge body, and an adjustment mechanism for adjusting the position of the cleaning mechanism.

[0019] The cleaning mechanism includes a cleaning part that extends between the stator 1 and the rotor 2 to strike the rotor 2, and a driving part for driving the cleaning part. The driving part is a cylinder 3, the cylinder body of which is mounted on the stator 1 via a connecting plate 4. The piston rod of the cylinder 3 passes through the stator 1 and extends between the stator 1 and the rotor 2. The cleaning part is a striking hammer 5 mounted on the piston rod of the cylinder 3. In this embodiment, the striking hammer 5 is a rubber hammer to avoid damaging the rotor 2. A mounting hole is provided on the stator 1, through which the piston rod of the cylinder 3 extends between the stator 1 and the rotor 2.

[0020] The adjusting mechanism is a self-locking hand-cranked screw slide, which includes fixed plates 6 at both ends, a slide rail 7 installed between the two fixed plates 6, and a screw 8 parallel to the slide rail 7 and rotatably connected between the two fixed plates 6. A slide 9 is installed on the screw 8 and the slide rail 7. One end of the screw 8 is fixed to the crank handle 10, and a locking part is installed at that end of the screw 8. The self-locking hand-cranked screw 8 and slide 9 are existing technologies, and their specific structure will not be described in detail here. The locking part uses a tightening bolt 11 to clamp the locking plate onto the screw 8, preventing the screw 8 from rotating. Its structure and working principle are also existing technologies and will not be described in detail here. Manually turning the crank handle 10 will move the slide 9.

[0021] The connecting plate 4 is fixed to the slide table 9. Guide rods 12 are respectively installed on the stators 1 on the upper and lower sides of the cylinder body of the cylinder 3. The guide rods 12 pass through the connecting plate 4 and guide the movement of the cylinder 3, thus stabilizing the position of the cylinder 3. The slide table 9 moves the connecting plate 4 by hand-cranking the handle 10, thereby moving the cylinder 3. When the position of the cylinder 3 is adjusted so that the piston rod of the cylinder 3 is fully extended, the stroke of the striking hammer 5 is 2-3 mm greater than the distance between the initial position of the striking hammer 5 and the rotor 2. This ensures that the cylinder 3 generates an impact force during extension and retraction without damaging the rotor 2, making it easy for the residual calcium citrate layer inside to fall off under external impact, thereby cleaning the calcium citrate.

[0022] In this embodiment, the cleaning mechanism is arranged in three groups from top to bottom, with an adjustment mechanism installed between every two groups. Simultaneous rotation of the two adjustment mechanisms by both hands moves all three cleaning mechanisms synchronously, facilitating installation and debugging. The positions of all three cleaning mechanisms can be adjusted at once, eliminating the need to adjust each mechanism individually. This convenient and time-saving operation improves the efficiency of installation and debugging. After the cleaning mechanism positions are adjusted, the locking plate is secured to the screw rod 8 by tightening the top bolt 11, preventing rotation and thus fixing the cleaning mechanism positions.

[0023] In operation, the centrifuge rotor 2 rotates rapidly under the drive of the pulley. Citric acid liquid enters through the feed inlet 13. Under the action of strong centrifugal force, the liquid is thrown to the outer layer through the filter cloth 14 and discharged from the drain outlet 15. The solid calcium citrate adheres to the filter cloth 14. After the solid calcium citrate on the filter cloth 14 reaches a certain thickness, the feed inlet 13 is closed and the water inlet 16 is opened to release water for washing. After washing, the centrifuge continues to spin dry. After the centrifuge is finished, the solid calcium citrate is scraped off by the scraper 17 and falls into the calcium citrate collection chamber 18. The remaining 6-10 mm of solid calcium citrate is cleaned by starting the cleaning mechanism.

[0024] During the cleaning process, cylinder 3 is activated, and the reciprocating extension and retraction of each cylinder 3 drives the hammer 5 to strike the rotor 2 for cleaning. During the cleaning process, the staff assists by manually rotating the rotor 2 to change the impact position and complete the cleaning of the rotor 2. The cleaned-off calcium citrate continues to fall into the calcium citrate collection chamber 18.

[0025] This invention significantly reduces the difficulty of cleaning and effectively avoids the problem of damage to the filter cloth 14 when cleaning from the inner layer. This invention can clean the remaining calcium citrate quickly and easily without damaging the filter cloth 14, taking only 15-20 minutes, which greatly shortens the cleaning time and improves work efficiency.

[0026] The position of the three cleaning mechanisms can be adjusted at once by adjusting the mechanism, eliminating the need to adjust the position of each cleaning mechanism individually. This makes the operation convenient, saves time and effort, and improves the efficiency of installation and debugging of this utility model.
