A cleaning mechanism for a doctor blade under-discharge centrifuge

Abstract

This utility model discloses a cleaning mechanism for a scraper-discharge centrifuge, including a tank body. A fixed frame is fixedly installed on the top side of the tank body, and a centrifugal assembly is arranged inside the fixed frame. A circular hole is opened on the top side of the tank body, and a lead screw is installed in the circular hole. The bottom end of the lead screw is rotatably connected to the inner wall of the bottom side of the tank body. A motor drives the rotating rod, which is driven by a transmission assembly consisting of a first synchronous pulley, a synchronous belt, and a second synchronous pulley. This causes the lead screw to rotate, making the sliding sleeve and scraper move up and down reciprocally inside the tank body. At the same time, a water pump draws water from the water tank, which is then sprayed out through a delivery pipe and an annular pipe to rinse the inner wall. The scraper adheres to the inner wall of the tank body and can scrape off residual impurities. Combined with the water flow rinsing, this significantly improves cleaning efficiency compared to traditional manual cleaning. Furthermore, during the centrifugation process, the scraper moves continuously, effectively preventing liquid adhesion. The scraper simultaneously performs the functions of unloading and cleaning, thereby greatly reducing cleaning time and improving equipment utilization.

Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, and in particular to a cleaning mechanism for a scraper-discharge centrifuge. Background Technology

[0002] With social development, continuous progress in industrial technology, and rising living standards, people have increasingly higher demands for food. This has led to the tremendous development of the food processing industry. Food processing refers to the processing of grains, feed, vegetable oils and sugars, slaughtering and meat processing, aquatic products, and vegetables, fruits, and nuts—all directly using agricultural, forestry, animal husbandry, and fishery products as raw materials. It is a type of agricultural product processing industry in a broad sense. Centrifuges are frequently used in food processing. They utilize centrifugal force to separate components in liquid-solid particle or liquid-liquid mixtures. However, after use, existing centrifuges often have residues on their inner walls, which, if not cleaned, can easily affect their performance.

[0003] Currently, traditional cleaning methods mostly rely on manual cleaning, requiring operators to enter the centrifuge and use tools such as brushes and scrapers to remove residues. This method not only consumes a lot of manpower and time and has low cleaning efficiency, but also poses safety risks to operators working in a confined space, such as accidental injury from rotating parts or contact with harmful materials. Therefore, a cleaning mechanism for scraper-discharge centrifuges is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cleaning mechanism for a scraper-discharge centrifuge, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cleaning mechanism for a scraper-discharge centrifuge includes a tank body. A fixing frame is fixedly installed on the top side of the tank body, and a centrifugal assembly is arranged inside the fixing frame. A circular hole is opened on the top side of the tank body, and a lead screw is arranged in the circular hole. The bottom end of the lead screw is rotatably connected to the inner wall of the bottom side of the tank body. A transmission assembly is arranged between the top end of the lead screw and the centrifugal assembly. A guide rod is fixedly installed inside the tank body. A sliding sleeve and a slider are respectively threaded and slidably sleeved on the outer sides of the lead screw and the guide rod. The same scraper is fixedly connected to the outer side of the sliding sleeve and the slider. The outer side of the scraper is in contact with the inner wall of the tank body. A cleaning assembly is arranged inside the tank body.

[0007] Preferably, the centrifuge assembly includes a motor fixedly installed on the top side of a fixed frame, the output end of the motor rotatably passing through the fixed frame and the tank and fixedly connected to a rotating rod, the bottom end of the rotating rod being fixedly connected to a connecting plate, the two sides of the connecting plate being fixedly connected to the same centrifuge cylinder, and the outer side of the centrifuge cylinder being provided with two cylinder doors.

[0008] Preferably, the transmission assembly includes a second synchronous pulley and a first synchronous pulley fixedly sleeved on the top of the lead screw and the outer side of the rotating rod, respectively, and the first synchronous pulley and the second synchronous pulley share the same synchronous belt.

[0009] Preferably, the cleaning assembly includes an annular tube fixedly installed on the inner wall of the top side of the tank, and multiple nozzles are arranged on the outer side of the annular tube, all of which face the inner wall of the tank.

[0010] Preferably, a water tank and a water pump are fixedly installed on the top side of the tank body, an extraction pipe is fixedly installed on one side of the water pump, the other end of the extraction pipe extends into the water tank, a delivery pipe is fixedly installed on the other side of the water pump, the other end of the delivery pipe passes through the tank body and is fixedly connected to the top side of the annular pipe, and the delivery pipe is connected to the annular pipe.

[0011] Preferably, the top and bottom sides of the tank are respectively provided with a feed inlet and a discharge outlet. The feed inlet is connected to the tank and faces the centrifuge cylinder, and a solenoid valve is provided on the outside of the discharge outlet.

[0012] Preferably, the outer side of the tank body is provided with two tank doors, which are arranged symmetrically.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The cleaning mechanism for the scraper-discharge centrifuge is driven by a motor to rotate the rotating rod, which in turn drives the lead screw to rotate through a transmission assembly consisting of a first synchronous pulley, a synchronous belt, and a second synchronous pulley. This causes the sliding sleeve and scraper to move up and down reciprocally inside the tank. At the same time, a water pump draws water from the tank and sprays it out through a delivery pipe and an annular pipe to rinse the inner wall. The scraper adheres to the inner wall of the tank, scraping off residual impurities. Combined with the water flow rinsing, this significantly improves cleaning efficiency compared to traditional manual cleaning. Furthermore, during the centrifugation process, the scraper moves continuously, effectively preventing liquid adhesion. This allows the scraper to simultaneously perform unloading and cleaning functions, thereby greatly reducing cleaning time and improving equipment utilization. Attached Figure Description

[0019] 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.

[0020] Reference Figure 1-4A cleaning mechanism for a scraper-discharge centrifuge includes a tank body 1. A fixed frame 2 is fixedly installed on the top side of the tank body 1. A centrifugal assembly is installed inside the fixed frame 2. A circular hole is opened on the top side of the tank body 1, and a lead screw 8 is installed in the circular hole. The bottom end of the lead screw 8 is rotatably connected to the inner wall of the bottom side of the tank body 1. A transmission assembly is installed between the top end of the lead screw 8 and the centrifugal assembly. A guide rod 10 is fixedly installed inside the tank body 1. A sliding sleeve 11 and a slider 12 are respectively threaded and slidably sleeved on the outer sides of the lead screw 8 and the guide rod 10. The same scraper 13 is fixedly connected to the outer sides of the sliding sleeve 11 and the slider 12. The outer side of the scraper 13 is in contact with the inner wall of the tank body 1. A cleaning assembly is installed inside the tank body 1. The transmission assembly includes a second synchronous pulley 9 and a first synchronous pulley 7 fixedly sleeved on the top end of the lead screw 8 and the outer side of a rotating rod 4. The first synchronous pulley 7 and the second synchronous pulley 9 share the same synchronous belt 24. A first synchronous pulley 7 is fixedly connected, and the first synchronous pulley 7 and the second synchronous pulley 9 share the same synchronous belt 24. Therefore, under the meshing transmission of the synchronous belt 24, the second synchronous pulley 9 will synchronously drive the lead screw 8 connected to it to rotate, thereby causing the sliding sleeve 11 threaded on the outside of the lead screw 8 to drive the scraper 13 connected to it to move up and down reciprocally inside the tank 1. Since the outer side of the scraper 13 is in contact with the inner wall of the tank 1, the scraper 13 can scrape off the residual impurities adhering to the inner wall of the tank 1 during the up and down movement. Combined with water rinsing, the cleaning effect can be greatly improved. In addition, the scraper 13 is also in a state of up and down movement during the centrifugation process, thereby avoiding the situation where the liquid adheres to the inner wall. Thus, the scraper 13 has the dual function of unloading and cleaning. Furthermore, the guide rod 10 and the slider 12 provided can provide stable guidance and limiting function when the scraper 13 moves up and down.

[0021] Specifically, the centrifugal assembly includes a motor 3 fixedly installed on the top side of the fixed frame 2. The output end of the motor 3 rotates through the fixed frame 2 and the tank 1 and is fixedly connected to a rotating rod 4. The bottom end of the rotating rod 4 is fixedly connected to a connecting plate 5. The two sides of the connecting plate 5 are fixedly connected to the same centrifugal cylinder 6. Two cylinder doors 22 are provided on the outside of the centrifugal cylinder 6. With the motor 3 installed, when the material is poured into the centrifugal cylinder 6 from the feed port 25, the motor 3 is started to drive the connecting plate 5 fixedly connected to the bottom end of the rotating rod 4 to rotate. Since the two sides of the connecting plate 5 are fixedly connected to the same centrifugal cylinder 6, the centrifugal cylinder 6 will rotate synchronously. The liquid will be thrown onto the inner wall of the tank 1 under the action of centrifugation, and then slide down to the bottom of the tank 1 with inertia and finally flow out from the discharge port 20.

[0022] Specifically, the cleaning assembly includes an annular pipe 14 fixedly installed on the inner wall of the top side of the tank 1, and multiple nozzles 15 arranged on the outer side of the annular pipe 14, all of which face the inner wall of the tank 1. A water tank 16 and a water pump 17 are fixedly installed on the top side of the tank 1. An extraction pipe 18 is fixedly installed on one side of the water pump 17, and the other end of the extraction pipe 18 extends into the water tank 16. A delivery pipe 19 is fixedly installed on the other side of the water pump 17, and the other end of the delivery pipe 19 passes through the tank 1 and is fixedly connected to the top side of the annular pipe 14. The delivery pipe 19 is connected to the annular pipe 14. After the material in the centrifuge 6 is taken out, the water pump 17 is started to drive the extraction pipe 18 to extract water from the water tank 16. The water is then transported along the delivery pipe 19 to the annular pipe 14 and sprayed out by the multiple nozzles 15 on the outer side of the annular pipe 14. Since the multiple nozzles 15 are all facing the inner wall of the tank 1, the water can wash the inner wall.

[0023] Specifically, the top and bottom sides of the tank 1 are respectively provided with a feed inlet 25 and a discharge outlet 20. The feed inlet 25 is connected to the tank 1 and faces the centrifuge drum 6. A solenoid valve 21 is provided on the outside of the discharge outlet 20. Two tank doors 23 are provided on the outside of the tank 1. The two tank doors 23 are symmetrically arranged. The feed inlet 25 and the discharge outlet 20 are used for feeding materials and discharging liquids. After centrifugation, the tank doors 23 and the drum door 22 can be opened in sequence to take out the material in the centrifuge drum 6. After taking out the material, the inner wall cleaning work can begin.

[0024] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be any conventional known device, such as a computer, that can control the operation of the electrical components mentioned in the article.

[0025] In use: First, pour the material into the centrifuge cylinder 6 through the feed inlet 25. After filling, start the motor 3. The motor 3 will rotate the connecting plate 5 fixedly connected to the bottom of the rotating rod 4. Since the centrifuge cylinder 6 is fixedly connected to both sides of the connecting plate 5, the centrifuge cylinder 6 will also rotate synchronously. Under the action of centrifugal force, the liquid in the material is thrown towards the inner wall of the tank 1, and then falls to the bottom of the tank 1 under the action of inertia and flows out from the discharge port 20. After the centrifuge cylinder 6 continues to rotate for a period of time and the liquid in the material is basically completely thrown out, turn off the motor 3. Then, open the two tank doors 23 and the two cylinder doors 22 in sequence. At this time, the remaining material in the centrifuge cylinder 6 can be taken out. After the material is taken out, close the cylinder door 22 and the tank door 23 in sequence. Next, clean the equipment. Start the water pump 17. The water pump 17 drives the extraction pipe 18 to draw water from the water tank 16. The water is transported to the annular pipe 14 through the conveying pipe 19, and then evenly distributed through the outside of the annular pipe 14. Multiple nozzles 15 spray water from the cloth. Since the nozzles 15 are all facing the inner wall of the tank 1, the sprayed water can effectively rinse the inner wall of the tank 1. While the water pump 17 is started for rinsing, the motor 3 is started again, driving the rotating rod 4 to rotate. The first synchronous wheel 7, which is fixedly sleeved on the outside of the rotating rod 4, rotates accordingly. Under the meshing transmission of the synchronous belt 24, the second synchronous wheel 9, which shares the same synchronous belt 24 with the first synchronous wheel 7, rotates synchronously. The rotation of the second synchronous wheel 9 then drives the lead screw 8 connected to it to rotate, so that the sliding sleeve 11 threaded on the outside of the lead screw 8 drives the scraper 13 to move up and down reciprocally inside the tank 1. Because the outside of the scraper 13 is in close contact with the inner wall of the tank 1, it can effectively scrape off the residual impurities attached to the inner wall of the tank 1 during the up and down movement. This, combined with the water rinsing, significantly improves the cleaning effect. In addition, during the rinsing of the inner wall of the tank 1, the water source also rinses the centrifuge cylinder 6 simultaneously, avoiding the need for separate manual cleaning of the centrifuge cylinder 6 and improving work efficiency.
