Description

Technical Field

[0001] The utility model relates to the field of internal inlet grille accessories, in particular to a cleaning device for a slag collecting trough of an internal inlet grille. Background Art

[0002] When the existing internal inlet grille is in operation, the mesh plate on one side goes down, passes through the sewage, picks up the dirt in the water, and goes up from the other side. When the mesh plate carries the dirt up to the top turning part, the dirt falls into the slag collecting tank under the turning part by its own weight and the flushing of the flushing water. Since the dirt falls irregularly, some of the dirt will hang on the top of the steel plates on both sides of the slag collecting tank and cannot be discharged with the flushing water. The dirt accumulates more and more. Since the distance between the mesh plate and the top of both sides of the slag collecting tank is very small, excessive accumulation of dirt will cause extrusion and friction between the mesh plate and the slag collecting tank, damage the mesh plate and cause failures, affecting the normal operation of the equipment.

[0005] In order to achieve the above utility model purpose, the technical solution of the utility model is:

[0006] A cleaning device for an inner inlet grid slag trough comprises a frame and a U-shaped slag trough with a top opening arranged inside the frame; flushing troughs are symmetrically arranged on the outer walls on both sides of the top opening end of the slag trough, a flushing waterway is formed between the flushing trough and the side walls of the slag trough, the bottom of the flushing trough is welded to the side walls of the slag trough, a water baffle is arranged on the top of the flushing trough, a flushing gap is left between the water baffle and the top edge of the slag trough, and a water inlet pipe is arranged on the side walls of the flushing trough; cleaning shafts that penetrate the frame and are parallel to the top edge of the slag trough are also symmetrically arranged above both sides of the top opening end of the slag trough, scrapers are evenly distributed circumferentially along the upper edge of the cleaning shaft, and the edge of the free end of the scraper is tangent to the flushing gap.

[0007] Furthermore, an adjustment component is arranged between the cleaning shaft and the frame, including a horizontal adjustment plate and a vertical adjustment plate; horizontal adjustment grooves are arranged on both sides of the horizontal adjustment plate, and vertical adjustment grooves are arranged on both sides of the vertical adjustment plate; a bearing seat is also arranged in the center of the vertical adjustment plate, and both ends of the cleaning shaft are arranged on the bearing seats.

[0010] Furthermore, a hand wheel is provided at one end of the cleaning shaft.

[0011] The beneficial effects of the utility model are:

[0012] The present application sets a cleaning shaft above both sides of the opening end of the top of the slag collecting trough. The dirt that originally fell on the steel plates on both sides of the top of the slag collecting trough will fall on the cleaning shaft. By rotating the cleaning shaft and coordinating with the flushing water sprayed from the flushing seam, the dirt on the cleaning shaft can be cleaned and fall into the slag collecting trough, so as to prevent the dirt from hanging on the steel plates on both sides of the top of the slag collecting trough and clogging the gap between the slag collecting trough and the mesh plate, thereby ensuring the normal operation of the equipment. The structural design is scientific, simple and practical. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present utility model will be described clearly and completely below in conjunction with the accompanying drawings.

[0018] A cleaning device for an inner inlet grid slag trough comprises a frame 1 and a U-shaped slag trough 2 with a top opening arranged inside the frame 1; flushing troughs 3 are symmetrically arranged on the outer walls on both sides of the top opening end of the slag trough 2, a flushing waterway 4 is formed between the flushing trough 3 and the side walls of the slag trough 2, the bottom of the flushing trough 3 is welded to the side walls of the slag trough 2, a water baffle 3.1 is arranged on the top of the flushing trough 3, a flushing gap 5 is left between the water baffle 3.1 and the top edge of the slag trough 2, and a water inlet pipe 3.2 is arranged on the side wall of the flushing trough 3; cleaning shafts 6 that penetrate the frame 1 and are parallel to the top edge of the slag trough 2 are also symmetrically arranged above both sides of the top opening end of the slag trough 2, scrapers 6.1 are evenly distributed circumferentially along the upper edge of the cleaning shaft 6, and the edge of the free end of the scraper 6.1 is tangent to the flushing gap 5.

[0019] Furthermore, the edge of the free end of the scraper 6.1 is tangent to the flushing slot 5. When the cleaning shaft 6 rotates, the flushing water from the flushing slot 5 can flush the dirt on the cleaning shaft 6 clean.

[0020] Furthermore, an adjustment component is arranged between the cleaning shaft 6 and the frame 1, including a horizontal adjustment plate 7 and a vertical adjustment plate 8; horizontal adjustment grooves 7.1 are arranged on both sides of the horizontal adjustment plate 7, and vertical adjustment grooves 8.1 are arranged on both sides of the vertical adjustment plate 8; a bearing seat 9 is also arranged in the center of the vertical adjustment plate 8, and both ends of the cleaning shaft 6 are arranged on the bearing seats 9.

[0021] Furthermore, the adjustment component is used to adjust the distance between the cleaning shaft 6 and the flushing seam 5. During installation, the horizontal adjustment plate 7 is installed first, and the position of the horizontal adjustment plate 7 is adjusted through the horizontal adjustment groove 7.1 (that is, the horizontal position of the cleaning shaft 6 is adjusted), and then the vertical adjustment plate 8 is installed on the horizontal adjustment plate 7. The position of the vertical adjustment plate 8 can be adjusted through the vertical adjustment groove 8.1 (that is, the vertical position of the cleaning shaft 6 is adjusted).

[0022] Furthermore, the height of the flushing slot 5 is 2-3 mm.

[0023] Furthermore, at least three scrapers 6.1 are provided.

[0024] Furthermore, a hand wheel 6.2 is provided at one end of the cleaning shaft 6.

[0025] How this application works:

[0026] The present application sets a cleaning shaft 6 above both sides of the top open end of the slag collecting trough 2. The dirt that originally fell on the steel plates on both sides of the top of the slag collecting trough 2 will fall on the cleaning shaft 6. By rotating the cleaning shaft 6 and cooperating with the flushing water sprayed from the flushing seam 5, the dirt on the cleaning shaft 6 can be cleaned and fall into the slag collecting trough 2, which can prevent the dirt from hanging on the steel plates on both sides of the top of the slag collecting trough 2 and blocking the gap between the slag collecting trough 2 and the mesh plate, thereby ensuring the normal operation of the equipment.
