Description

Technical Field

[0001] This utility model relates to the field of horizontal centrifuge technology, specifically a self-cleaning mechanism for the scraper hopper of a horizontal centrifuge. Background Technology

[0002] Currently, in chemical production, solid-liquid mixtures are usually separated by centrifuges. Commonly used centrifuges are mainly divided into filter centrifuges and sedimentation centrifuges. Filter centrifuges mainly use a rotating drum and filter cloth to separate solid-liquid mixtures. The liquid passes through the filter cloth, while the solid material is retained on the surface of the filter cloth. Finally, the material on the surface of the filter cloth is scraped off by a scraper.

[0003] Horizontal centrifuges are generally equipped with automatic unloading devices. During unloading, the material on the side wall of the inner rotating drum is scraped off by a scraper and then falls into the discharge hopper for discharge. When the scraper scrapes off the material, the material often adheres and accumulates near the scraper, affecting the continued scraping and discharge of the material. To address this issue, a self-cleaning mechanism for the scraper hopper of a horizontal centrifuge is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a self-cleaning mechanism for the scraper hopper of a horizontal centrifuge, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A self-cleaning mechanism for the scraper hopper of a horizontal centrifuge includes:

[0007] The frame has a rotating drum mounted inside;

[0008] Close the cover and rotate it to install it at the open end of the frame;

[0009] A discharge assembly is installed on the cover. The discharge assembly includes a discharge pipe and a discharge hopper. The discharge pipe is fixedly installed on the cover. One end of the discharge hopper is fixedly connected to a rotating shaft. The rotating shaft is rotatably installed between the discharge hopper and the cover. The top of the discharge hopper has an opening. A scraper is installed on one side of the opening of the discharge hopper.

[0010] A cleaning component is located on one side of the unloading hopper. The cleaning component includes a water spray pipe for spraying water onto the scraper. The cleaning component has multiple water spray holes.

[0011] Furthermore, the cleaning assembly also includes a docking seat, one end of which is rotatably mounted with a long tube, one end of which is fixedly connected to a rocker arm, one end of which is connected to one end of a water spray pipe, one end of which is fixedly connected to a long groove, one side of which is fixedly mounted with a slide block, the top of which is slidably connected to the long groove block, and the other end of which penetrates the cover and extends to the outside of the cover.

[0012] Furthermore, the water spray pipe is rotatably connected to the rocker arm, and the water spray hole is inclinedly arranged on the water spray pipe.

[0013] Furthermore, the rotation axis of the rotating shaft is located above the rotation axis of the drum.

[0014] Furthermore, the long tube is positioned directly below the rotation axis.

[0015] Furthermore, the bottom end of the unloading hopper is arc-shaped, and a material leakage groove is provided at the bottom end of the unloading hopper. The bottom end of the unloading hopper is coupled to the top end of the discharge pipe.

[0016] Furthermore, a hydraulic cylinder is rotatably mounted on the cover, and a rocker arm is fixedly mounted on the rotating shaft, with the output end of the hydraulic cylinder rotatably connected to one end of the rocker arm.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. Through the setting of the cleaning component, after the unloading hopper finishes unloading, the unloading hopper deflects downward, causing the water spray pipe to move to the front position of the scraper. Then the water spray pipe sprays water outward to wash the material adhering to the scraper and the drum. When the scraper deflects upward to scrape the material, the water spray pipe moves from the front and above of the scraper to the bottom of the water spray pipe to avoid contact with the drum, thus washing the scraper.

[0019] 2. By setting up the water spray pipe and rocker arm, and by tilting the water spray holes, when the cleaning component sprays water outward through the water spray holes, the water spray pipe is back-rotated, which facilitates rinsing of the unloading hopper and scraper. Furthermore, by setting the deflection angle of the unloading hopper, when rinsing, if the unloading hopper points diagonally upward, the cleaning water entering the unloading hopper flows into the discharge pipe and is discharged. If the unloading hopper points diagonally downward, the cleaning water entering the unloading hopper will be poured into the rotating drum, which facilitates rinsing of the discharge pipe.

Detailed Implementation

[0028] 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.

[0029] Please see Figures 1-3 In this embodiment of the present invention, a self-cleaning mechanism for the scraper hopper of a horizontal centrifuge includes a cover 100, a frame 200, a discharge assembly 300, and a cleaning assembly 400. A rotating drum 210 is rotatably mounted inside the frame 200. The cover 100 is rotatably mounted on the open end of the frame 200. The discharge assembly 300 is mounted on the cover 100 and includes a discharge pipe 310 and a discharge hopper 320. The discharge pipe 310 is fixedly mounted on the cover 100. On the 0, a rotating shaft 323 is fixedly connected to one end of the unloading hopper 320. The rotating shaft 323 is rotatably installed between the hopper and the cover 100. An opening is provided at the top of the unloading hopper 320. A scraper 322 is installed on one side of the opening of the unloading hopper 320. A cleaning component 400 is located on one side of the unloading hopper 320. The cleaning component 400 includes a water spray pipe 440, which is used to spray water onto the scraper 322. Multiple water spray holes 441 are provided on the cleaning component 400.

[0030] Specifically, during centrifugation, the discharge hopper 320 is in an offset state, which increases the gap between the discharge hopper 320 and the rotating drum 210. After the material is centrifuged in the rotating drum 210, the discharge hopper 320 deflects upward, causing the scraper 322 to approach the rotating drum 210. As the rotating drum 210 rotates, the scraper 322 scrapes off the material, allowing the material to be guided from the discharge hopper 320 into the discharge pipe 310 for discharge. After the discharge hopper 320 has finished discharging, it deflects downward, causing the water spray pipe 440 to move to the position in front of the scraper 322. Then, the water spray pipe 440 sprays water outward to wash the material adhering to the scraper 322 and the rotating drum 210. When the scraper 322 deflects upward to scrape the material, the water spray pipe 440 moves from the front and above of the scraper 322 to the bottom of the water spray pipe 440 to avoid contact with the rotating drum 210.

[0031] like Figures 3-7 As shown, in this embodiment, the cleaning assembly 400 further includes a docking seat 410. A long tube 420 is rotatably mounted on one end of the docking seat 410. A rocker arm 430 is fixedly connected to one end of the long tube 420. One end of the rocker arm 430 is connected to one end of the water spray pipe 440. A long groove 330 is fixedly connected to one end of the unloading hopper 320. A slide 450 is fixedly mounted on one side of the rocker arm 430. The top end of the slide 450 is slidably connected to the long groove 330. The other end of the docking seat 410 passes through the cover 100 and extends to the outside of the cover 100. The water spray pipe 440 and the rocker arm 430 are connected... The water spray hole 441 is tilted on the water spray pipe 440. The center of the rotating shaft 323 is located above the center of the rotating shaft 323 of the drum 210. The long pipe 420 is located directly below the rotating shaft 323. The bottom end of the unloading hopper 320 is arc-shaped and has a material leakage groove 321. The bottom end of the unloading hopper 320 is coupled to the top end of the discharge pipe 310. A hydraulic cylinder 500 is rotatably mounted on the cover 100. A rocker arm 510 is fixedly mounted on the rotating shaft 323. The output end of the hydraulic cylinder 500 is rotatably connected to one end of the rocker arm 510.

[0032] In this embodiment, the hydraulic cylinder 500 drives the rotating shaft 323 to rotate, thereby controlling the deflection of the unloading hopper 320. When the unloading hopper 320 deflects downward, the long groove 330 and the slide 450 drive the rocker arm 430 to deflect downward. Due to the long pipe 420 being positioned below the rotating shaft 323, during the downward deflection of the unloading hopper 320 and the water spray pipe 440, the water spray pipe 440 gradually moves to an oblique position above the opening of the unloading hopper 320, thereby allowing the water spray pipe 440 to spray water onto the scraper 322 for cleaning. This is achieved through the water spray holes 441. The tilting setting allows the water spray pipe 440 to be backflushed and rotated when the cleaning component 400 sprays water outward through the water spray hole 441, thus facilitating the rinsing of the unloading hopper 320 and the scraper 322. Furthermore, by setting the deflection angle of the unloading hopper 320, during rinsing, when the unloading hopper 320 points diagonally upward, the cleaning water flowing into the unloading hopper 320 flows into the discharge pipe 310 and is discharged. When the unloading hopper 320 points diagonally downward, the cleaning water entering the unloading hopper 320 is poured into the rotating drum 210, thus facilitating the rinsing of the discharge pipe 310.
