Description

Technical Field

[0001] The utility model relates to the technical field of sludge extrusion, in particular to a sludge extrusion device. Background Art

[0002] When sewage is treated, it will be separated into solid and liquid through an extruder, that is, the liquid in the sewage is squeezed out of the sewage through an extrusion belt, and then the remaining sludge in the sewage remains on the extrusion belt and moves with the extrusion belt to the discharge place for discharge. However, the sludge is separated from the sewage by extrusion, so there is a phenomenon that the sludge is attached to the extrusion belt due to extrusion. The sludge cannot fall off the extrusion belt automatically, which affects the subsequent work of the extrusion belt. For this reason, we propose a sludge extrusion device that is easy to clean the sludge. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides Figure 1-4 A sludge extrusion device shown includes an extruder body 101, a discharge mechanism and a scraper mechanism. The discharge mechanism is arranged on the front side of the extruder body 101, and is used to guide the sludge discharged from the extruder body 101. The discharge mechanism includes a guide plate 301, and the guide plate 301 is fixedly connected to the sludge discharge position of the extruder body 101. A fixing plate is arranged at the bottom end of the guide plate 301. The fixing plate is penetrated by bolts and screwed into the extruder body 101, so that the guide plate 301 can be fixed on the extruder body 101, and the guide plate 301 is inclined, so that the sludge discharged from the extruder body 101 can be stably guided and discharged through the guide plate 301.

[0023] In a preferred embodiment, the scraper mechanism is movably arranged on the front side of the extruder body 101, and the scraper mechanism includes a scraper plate 201 movably arranged on the discharge mechanism. The scraper mechanism can move along the direction of the discharge mechanism so that the scraper plate 201 is pressed against the extrusion belt in the extruder body 101 and scrapes off the sludge attached to the extrusion belt. The scraper plate 201 overlaps with at least a part of the guide plate 301, and a moving mechanism is arranged between the scraper plate 201 and the guide plate 301. The scraper plate 201 is moved up and pressed against the extrusion belt through the moving mechanism, so that the scraper plate 201 can scrape off the sludge attached to the extrusion belt. The scraped sludge will move along the scraper plate 201, and then slide onto the guide plate 301 and slide out through the guide plate 301, thereby avoiding the sludge from adhering to the extrusion belt and ensuring the stability of sludge extrusion.

[0024] Among them, the moving mechanism includes a slide groove 401, which is opened at the top of the guide plate 301. A slider 402 that can slide along the slide groove 401 is arranged inside the slide groove 401. The slider 402 is fixedly connected to the bottom end of the scraper plate 201. An extrusion mechanism is arranged between the slider 402 and the slide groove 401. The slider 402 can slide in the slide groove 401, so that the scraper plate 201 can stably slide on the top of the guide plate 301, so that the sludge sliding down from the scraper plate 201 can stably slide onto the guide plate 301, thereby ensuring the stability of the sludge discharge scraped off by the guide plate 301.

[0025] Preferably, the extrusion mechanism includes a spring 403, which is arranged between the outer wall of the slider 402 and the inner wall of the slide groove 401. A limiting mechanism is arranged inside the slide groove 401. Through the elastic action of the spring 403 and the positioning of the spring 403 by the inner wall of the slide groove 401, the spring 403 always squeezes the slider 402, so that the slider 402 always has a tendency to move upward in the slide groove 401, so that the scraper plate 201 connected to the slider 402 always has a tendency to move upward, which can ensure that the scraper plate 201 can stably resist the extrusion belt to work, thereby improving the working stability of the scraper plate 201.

[0026] Furthermore, the limiting mechanism includes a fixed shaft 501, which is fixedly connected to the inner wall of the slide groove 401, and a spring 403 is sleeved on the outer wall of the fixed shaft 501. The outer wall of the slider 402 is provided with a movable hole 502, and the outer wall of the fixed shaft 501 is movably connected with the inner wall of the movable hole 502. The movable hole 502 and the fixed shaft 501 are mutually limited, so that the slider 402 can only move in the axial direction of the fixed shaft 501 installed in the slide groove 401, and the axial direction of the fixed shaft 501 is parallel to the surface of the guide plate 301, so that the scraper plate 201 can stably move on the surface of the guide plate 301, further ensuring the working stability of the scraper plate 201. At the same time, through the limitation of the fixed shaft 501 and the movable hole 502, the slider 402 slides in the slide groove 401. The slider 402 will not separate from the slide groove 401, which can ensure that the scraper plate 201 can work stably on the surface of the guide plate 301. Multiple groups of contact mechanisms are arranged between the scraper plate 201 and the guide plate 301, and multiple groups of stabilizing mechanisms are arranged between the scraper plate 201 and the guide plate 301. The stabilizing mechanism includes a limit groove 801, which is opened at the top of the guide plate 301, and a limit block 802 sliding along the limit groove 801 is arranged inside the limit groove 801. The limit block 802 is fixedly connected to the bottom end of the scraper plate 201. There are at least two groups of stabilizing mechanisms, which are inserted into the limit groove 801 and slide in the limit groove 801, thereby increasing the connection points between the scraper plate 201 and the guide plate 301, thereby making the connection strength between the scraper plate 201 and the guide plate 301 higher, thereby ensuring the stability of the scraper plate 201 when used.

[0027] Furthermore, the contact mechanism includes a rolling ball 702, a ball groove 701 is opened at the top of the guide plate 301, and the rolling ball 702 is movably clamped inside the ball groove 701. The outer wall of the rolling ball 702 is fitted with the bottom end of the scraper plate 201. When the scraper plate 201 slides on the surface of the guide plate 301, the bottom end of the scraper plate 201 is always against the outer wall of the rolling ball 702, which can make the friction of the scraper plate 201 when sliding on the top of the guide plate 301 lower, thereby ensuring the smoothness of the scraper plate 201 sliding on the surface of the guide plate 301.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
