Description

Technical Field

[0001] The utility model relates to the relevant field of vacuum filters, in particular to an auxiliary slag unloading device for vacuum filters. Background Art

[0002] A vacuum filter is a device that uses vacuum negative pressure as a driving force to achieve solid-liquid separation. Under the action of vacuum negative pressure (0.04-0.07MPa), the liquid in the suspension is pumped away through the filter medium (filter cloth), while the solid particles are retained by the medium, thereby achieving liquid and solid separation. Structurally, the filter section is arranged along the horizontal length direction, and can continuously complete operations such as filtering, washing, drying, and filter cloth regeneration. After filtration, the material needs to be unloaded through an auxiliary slag unloading device.

[0003] The existing patent: CN109731387A discloses a rotary table vacuum filter auxiliary slag unloading device, comprising a spiral slag unloading machine and a slag unloading bucket, characterized in that the slag unloading port of the spiral slag unloading machine (1) is provided with a slag unloading bucket (3), a slag unloading scraper (2) is installed on the front wall of the slag unloading bucket (3), and a reduction motor (4) is also installed outside the front wall of the slag unloading bucket (3), and the slag unloading scraper (2) is driven by the reduction motor (4). The spiral slag unloading machine (1) sends the phosphogypsum slag to the slag unloading port, and part of the phosphogypsum slag is thrown onto the front wall of the slag unloading bucket (3), adheres to the front wall and accumulates, and the reduction motor (4) drives the slag unloading scraper (2) to rotate, and the accumulated phosphogypsum slag is scraped off. The device solves the problems of phosphogypsum slag sticking and piling up at the slag discharge hopper mouth, uneven material discharge, large clumps of phosphogypsum slag falling onto the slag conveyor belt and causing spillage, and even blockage of the slag discharge hopper mouth, resulting in system tripping. The device realizes real-time blockage clearing and is suitable for dry slag discharge of wet-process phosphoric acid.

[0004] The above patents or existing auxiliary slag unloading devices have the following problems:

[0005] The existing auxiliary slag unloading device is prone to agglomeration and high viscosity of materials after filtration, which causes the materials to stick to the surface of the auxiliary scraper when the auxiliary scraper is scraping the materials, and also causes the problem of slow material discharge.

[0012] Preferably, side plates are provided on both side surfaces of the cushion block, and the cam is located between the two side plates.

[0013] Preferably, when the vibration plate and the auxiliary scraper are in the same plane, the clockwork spring is in a stressed state.

[0014] Beneficial effects of the utility model:

[0015] The utility model is provided with a material vibrating structure. When the motor is turned on, the driven teeth and the fixed shaft rotate, thereby driving the cam to rotate. Because the vibration plate and the auxiliary scraper are in the same plane, the spring is in a stressed state. Therefore, the vibration plate will always be attached to the surface of the cam.

DETAILED DESCRIPTION

[0022] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0023] See also Figure 1 and Figure 2 The utility model provides an auxiliary slag unloading device for a vacuum filter, comprising a mounting plate 1, which is fixed at the discharge port of the vacuum filter by bolts, a clamping plate 2 is welded on the surface of the mounting plate 1, an auxiliary scraper 3 is installed in the clamping plate 2 and fixed by bolts, and one end of the auxiliary scraper 3 is close to the surface of the drum of the vacuum filter, the surface of the drum carries the material under the auxiliary scraper 3, thereby realizing the auxiliary unloading of the vacuum filter, and a material shaking structure 4 is arranged in the auxiliary scraper 3.

[0024] See also Figure 2 , Figure 3 , Figure 4 and Figure 5 The utility model provides an auxiliary slag unloading device for a vacuum filter, wherein the material vibration structure 4 comprises a vibration plate 41, wherein the vibration plate 41 is arranged in the auxiliary scraper 3, wherein a fixing plate 42 is integrally formed at the bottom end surface of the rear end of the vibration plate 41, and the fixing plate 42 is provided with two fixing plates 42 respectively located at the left and right ends of the vibration plate 41, wherein a rotating rod 43 is integrally formed on the surface of the fixing plate 42, wherein the rotating rod 43 extends into the interior of a fixing seat 44 at the bottom end surface of the auxiliary scraper 3, and the rotating rod 43 is rotatably connected with the fixing seat 44, wherein a spring 45 is assembled inside the fixing seat 44, wherein one end of the spring 45 is fixed to the fixing seat 44, and the other end is fixed to the surface of the rotating rod 43;

[0025] The bottom end surface of the auxiliary scraper 3 is fixed with an organic box 46 by bolts, and a motor 47 is fixed with bolts on the surface of the organic box 46. The output shaft of the motor 47 extends into the interior of the organic box 46 and is connected with a driving tooth 48 assembled inside the organic box 46. A driven tooth 49 meshing with the driving tooth 48 is fixed with a fixed shaft 410 in the middle of the driven tooth 49. The fixed shaft 410 is rotatably connected with the organic box 46. A cam 411 is arranged on the surface of the fixed shaft 410. The cam 411 fits with a pad 412 fixed on the bottom end surface of the vibration plate 41, and the cam 411 slides along the surface of the pad 412, which can avoid the cam 411 from contacting the vibration plate 41, effectively reducing the friction of the cam 411 and improving the service life of the cam 411. The surfaces of both sides of the pad 412 are integrally formed with side plates 413, and the cam 411 is located between the two side plates 413, which can position the cam 411.

[0026] The bottom end surface of the vibration plate 41 is fixed with a limiting plate 401. When the cam 411 lifts the vibration plate 41, the limiting plate 401 abuts against the bottom end surface of the auxiliary scraper 3 to limit the vibration plate 41. When the vibration plate 41 and the auxiliary scraper 3 are in the same plane, the spring 45 is in a stressed state, so that the vibration plate 41 is always attached to the surface of the cam 411.

[0027] When the material is slowly discharged from the surface of the auxiliary scraper 3, the motor 47 is turned on, and the motor 47 drives the driving tooth 48 to rotate. Since the driven tooth 49 is meshed and connected with the driving tooth 48, when the driving tooth 48 rotates, it will drive the driven tooth 49 to rotate. The rotation of the driven tooth 49 will drive the fixed shaft 410 to rotate, thereby driving the cam 411 to rotate. Since the vibration plate 41 and the auxiliary scraper 3 are in the same plane, the spring 45 is in a stressed state. Therefore, the vibration plate 41 will always be attached to the surface of the cam 411. Therefore, when the cam 411 rotates downward, under the action of the spring 45, the rotating rod 43 will rotate and drive the vibration plate 41 to rotate downward. Under the continuous rotation of the cam 411, the vibration plate 41 will rotate up and down, thereby generating vibration. Under the action of the vibration, the material of the auxiliary scraper 3 will accelerate and move, effectively avoiding slow or no material discharge.
