Description

Technical Field

[0001] The utility model relates to the technical field of horizontal screw centrifuges, in particular to an accumulated material cleaning device. Background Art

[0002] The horizontal spiral centrifuge is a spiral unloading sedimentation centrifuge. The blades on the spiral pusher push the material to the small end of the drum, and the material is discharged through the slag discharge port of the collection box by gravity. The liquid phase overflows through the overflow hole at the large end of the drum. This cycle continues to achieve the purpose of continuous separation.

[0003] The existing centrifuge separates sticky solid slag. The inside of the centrifuge slag collecting box is prone to material accumulation and is difficult to clean and wash. After a period of time, the material layer inside the slag collecting box at the slag outlet becomes thicker and thicker, and the slag collecting box at the slag outlet is filled with increasingly thick solid slag and cannot discharge the slag normally. At the same time, the increasingly thick solid slag rubs against the conical drum, causing wear on the outer circle of the conical drum, affecting the dynamic balance of the centrifuge, resulting in increased vibration and noise, and increased energy consumption of the centrifuge. In severe cases, it may even cause the centrifuge to overload and stop, making the centrifuge unable to operate normally and continuously. After a period of use, the upper cover of the collection box must be opened and cleaned before the centrifuge can work normally. The current situation has seriously reduced the service life of the equipment and affected production efficiency. Utility Model Content

[0004] The utility model aims to provide a horizontal screw centrifuge with a collection box anti-material accumulation system to solve the above technical problems.

[0005] The technical problem solved by the present invention can be achieved by adopting the following technical solutions:

[0006] A horizontal screw centrifuge with a collection box anti-material accumulation system comprises a horizontal screw centrifuge, the horizontal screw centrifuge has a base, a bearing seat end cover and a collection box, the inner wall of the collection box has a circular contour, and also comprises a material accumulation cleaning system; the material accumulation cleaning system comprises a reduction motor system and a cleaning device; the reduction motor system comprises a motor and a gearbox, the output shaft of the motor is connected to the input shaft of the gearbox, and the motor and the gearbox are arranged on the base; the cleaning device comprises a rolling brush, the rolling brush comprises a brush body and a rotating bracket, and the brush body is arranged on the rotating bracket; the output shaft of the gearbox is linked to the rotating bracket; the cleaning part of the brush body faces the inner wall of the collection box, and the rotating trajectory fits at least part of the contour of the inner wall of the collection box, and the gap between the brush body and the inner wall of the collection box is 2 to 10 mm.

[0007] Since the sticky solid slag is thrown out by the cone drum at high speed along the tangential direction and adheres to the collection box at the slag outlet, it is difficult for the solid slag to separate by itself by gravity alone. Therefore, the utility model is provided with a reducer. After the power motor is decelerated through the gearbox, it drives the cleaning component to physically act on the accumulated material in the collection box, forcibly separating the accumulated material from the inner wall of the collection box, thereby cutting off the material layer inside the collection box, so that the solid slag cannot accumulate and then rub against the cone drum, eliminating the wear of the outer circle of the cone drum, extending the service life of the horizontal screw centrifuge, and improving the utilization efficiency of the equipment.

[0008] Furthermore, it also includes a transmission system, which includes a mounting seat, a bearing and a rotating ring; the mounting seat is a cylindrical component with a flange at one end, the central axis of the mounting seat is consistent with the central axis of the bearing seat end cover, and one end of the mounting seat flange is connected to the bearing seat end cover; the bearing is fixedly connected to the mounting seat; the rotating ring is slidably and rotatably sleeved on the bearing; the transmission system also includes a driving sprocket and a driven sprocket; the output shaft of the gearbox is connected to the driving sprocket, the driving sprocket is connected to the driven sprocket through a roller chain, and the driven sprocket is fixedly connected to one end of the rotating ring; the driven sprocket is arranged concentrically with the rotating ring; a rotating bracket of a cleaning device is arranged at the other end of the rotating ring; the rotating ring is arranged concentrically with the rotating bracket.

[0009] In the utility model, the mounting seat is a mounting shaft with a flange at one end, the flange portion is fixedly connected to the bearing seat end cover, the mounting seat shaft body is sequentially sleeved with a bearing bush and a rotating ring, and the rotating ring can slide and rotate relative to the bearing bush.

[0010] The rotating bracket of the cleaning assembly is set on the rotating ring. The rotating bracket is connected to the brush body through the mounting rod. The brush body is driven to rotate along the axis of the mounting seat through the rotating ring to form a trajectory close to the contour of the inner wall of the collection box, thereby cleaning the accumulated materials on the inner wall of the collection box to prevent the accumulation of accumulated materials.

[0011] The output shaft of the reducer is connected to the driving sprocket, and the driven sprocket is linked to the rotating ring. Through the roller chain, the driving sprocket drives the driven sprocket to rotate at a low speed and high torque. There is an oil seal lubrication between the bearing and the rotating ring, which can simplify the lubrication structure and reduce the manufacturing cost while ensuring long-term operation.

[0012] Further optimization also includes a labyrinth seal, which includes an inner gear ring and an outer gear ring, which are connected to each other; the inner gear ring is arranged on a rotating ring between the driven sprocket and the rotating bracket; an annular opening is arranged at the end of the collection box, and the outer gear ring is embedded in the annular opening.

[0013] The function of the labyrinth seal is to prevent the leakage of liquid in the collection box. The inner and outer tooth rings are sleeved together to form a series of interception gaps and expansion cavities between the inner and outer teeth. When the liquid passes through the gaps in the tortuous labyrinth, a throttling effect will be produced, thereby achieving the purpose of preventing the leakage of the liquid from further leakage.

[0014] Further optimization also includes a circular baffle, called the end baffle; a flange is provided on the outer wall of the bearing shell; the inner diameter of the center hole of the end baffle is larger than the outer diameter of the bearing shell, and smaller than the outer diameter of the flange of the bearing shell; the end baffle is connected to the bearing shell, close to the end cover of the bearing seat; the rotating ring and the driven sprocket are fixedly connected to the end face of the end baffle.

[0015] In the utility model, the end baffle plate is used to connect the rotating ring and the driven sprocket together, so that the driven sprocket drives the rotating ring to rotate; the end baffle plate cooperates with the baffle flange of the bearing bush to prevent the rotating ring from detaching from the bearing bush.

[0016] Furthermore, the brush body is a scraper; the scraper is a long steel plate made of stainless steel, and the side of the long steel plate is provided with teeth.

[0017] In the utility model, teeth are arranged on both sides of the long steel plate to form a steel scraper, and the scraper is used to approach the inner wall of the collection box to scrape the accumulated material adhering to the inner wall and discharge it to the slag outlet. The scraper needs to contact the solid slag, needs to have a certain hardness, and needs to be corrosion-resistant and easy to clean, so stainless steel is selected.

[0018] Further optimization includes at least two scrapers, which are connected in an L shape; one of the scrapers is perpendicular to the axis of the rotating ring; and the other scraper is parallel to the axis of the rotating ring.

[0019] The sticky solid slag is thrown out by the cone drum at high speed along the tangential direction and adheres to the collection box at the slag outlet. The accumulated materials are concentrated on the end face and radial surface of the collection box near the cone drum. In the utility model, two scrapers are used, and the scrapers are perpendicular to each other to form an L shape. The scraper connected to the mounting rod is used to clean the accumulated materials on the end face of the collection box, and the other scraper is used to clean the accumulated materials on the radial surface of the collection box. Teeth are arranged on both sides of the scraper. When one side of the teeth is damaged, the other side can be replaced for continued use, which can increase the service life and reduce the cost of use. The scraper continuously cleans the accumulated materials under the action of the reducer, protects the cone drum from wear, reduces downtime for cleaning, improves the use efficiency of the horizontal spiral centrifuge, and improves production efficiency.

[0020] Furthermore, the brush body is a compressed air nozzle, and the compressed air nozzle faces the inner wall of the collection box; it also includes a compressed air pipeline; the compressed air nozzle is connected to the compressed air pipeline.

[0021] The second cleaning method of the utility model utilizes the high air pressure formed by the compressed air to blow off the accumulated materials on the inner wall of the collection box, thereby preventing the accumulated materials from piling up on the inner wall of the collection box.

[0022] Furthermore, the brush body is a high-pressure water gun; the high-pressure water gun faces the inner wall of the collection box; it also includes a high-pressure water pipeline; the high-pressure water gun is connected to the high-pressure water pipeline.

[0023] The third cleaning method of the utility model utilizes high-pressure water to flush the accumulated materials on the inner wall of the collection box and dissolve the viscosity of the solid slag itself, so that the accumulated materials cannot accumulate on the inner wall of the collection box.

[0024] The utility model utilizes a speed reducer to drive a cleaning device to continuously and uninterruptedly brush the solid slag thrown out of the centrifuge slag outlet and adhered to the slag outlet collection box, which can prevent the material layer from becoming thicker and thicker, thereby causing the slag outlet of the collection box to be blocked due to difficulty in cleaning and washing. The utility model has the beneficial effect of solving the technical problems of vibration, increased noise and increased energy consumption caused by the wear of the small end cover shaft and the outer circle of the conical drum caused by the accumulated material, thereby affecting the dynamic balance of the centrifuge, and preventing the centrifuge from stopping due to overload, thereby preventing the centrifuge from being unable to operate normally and continuously.
