Description

Technical Field

[0001] The invention relates to a wastewater treatment device capable of filtering waste residues and removing sludge. Background Art

[0002] In existing wastewater treatment technologies, the treatment of wastewater containing waste residue and sludge usually relies on a combination of traditional sedimentation tanks and filtration systems. These systems use gravity to settle heavier waste residue and sludge to the bottom, and then remove suspended matter and some fine particles through subsequent filtration equipment. However, this technical solution has significant disadvantages: 1. Low treatment efficiency: Traditional sedimentation tanks require a long residence time to ensure the effective sedimentation of waste residue and sludge, resulting in a long overall treatment process. 2. Large footprint: In order to meet sufficient sedimentation time, sedimentation tanks often need to be designed to be larger, which is a considerable challenge for areas with tight land resources. 3. High maintenance cost: Filtration equipment is prone to clogging and requires frequent cleaning or replacement of filters, which increases operating costs and maintenance complexity. 4. Limited treatment effect: Insufficient removal capacity for fine particles and soluble pollutants, making it difficult to meet increasingly stringent environmental emission standards.

DETAILED DESCRIPTION

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings:

[0020] Example 1: Figure 1 , 2 As shown in Figures 4 and 5, the present invention discloses a wastewater treatment device capable of filtering waste residues and removing sludge, comprising a rectangular box body 1, wherein a longitudinal partition plate 7 is arranged in the box body 1, wherein the longitudinal partition plate 7 divides the cavity in the box body 1 into a left filter chamber 5 and a right slag collecting chamber 6, wherein a sludge discharge port 3 communicating with the left filter chamber 5 and a slag discharge port 4 communicating with the right slag collecting chamber 6 are respectively arranged at the bottom of the front side wall of the box body 1, a drainage port 2 is arranged at the upper part of the left side wall of the box body 1, and an electric telescopic rod 12 which can be telescopically extended forward and backward is longitudinally arranged at the rear top of the left side wall of the box body 1, wherein the front end of the electric telescopic rod 12 is connected to a supporting crossbeam 8 extending left and right. A plurality of elastic ropes 24 that can be extended forward and backward are connected between the supporting crossbeam 8 and the rear side wall of the box body 1. A filter screen 25 that can cover the top of the left filter chamber 5 when the elastic rope 24 is stretched is laid on the elastic rope 24. The filter screen 25 is flush with the top of the longitudinal partition 7. A plurality of partition rods 26 fixed on the elastic rope 24 and extending left and right are arranged side by side above the filter screen 25. A mud paddle 27 that is parallel to the front and rear side walls of the box body 1 and whose lower end extends to the bottom of the box body 1 is connected below the two middle partition rods 26. The mud paddle 27 has a plurality of filter holes 28.

[0021] A supporting cross bar 14 with its end extending to the top of the longitudinal partition 7 is mounted above the supporting cross beam 8, and a connecting rod I9, a connecting rod II10 and a connecting rod III11 are rotatably connected between the end of the supporting cross bar 14 and the upper part of the rear side wall of the box body 1 from front to back. When the elastic rope 24 retracts backward to the end of the stroke, the rear end of the connecting rod I and the front end of the connecting rod III both swing to the left and push the connecting rod II to move to the left to the left side of the left filter chamber 5. When the elastic rope 24 extends forward to the end of the stroke, the rear end of the connecting rod I and the front end of the connecting rod III both swing to the right and push the connecting rod II to move to the right to the right side of the left filter chamber 5; a plurality of slag removing rods 18 are vertically connected below the bottom of the connecting rods I, II and III, and the lower ends of the slag removing rods 18 are in contact with the filter screen 25. In order to provide support, a support vertical rod 13 is vertically connected to the left end of the support crossbeam 8, a support crossbeam 14 extending left and right and parallel to the support crossbeam 8 is connected to the top of the support vertical rod 13, and a groove 15 is provided at the bottom of the right end of the support crossbeam 8 to slide and buckle on the top of the longitudinal partition 7. A brush is provided at the lower end of the slag removal rod 18 to contact the filter screen 25.

[0022] When in use, the electric telescopic rod 12 is in a retracted state, the rear end of the connecting rod I and the front end of the connecting rod III both swing to the left and push the connecting rod II to move to the left to the left side of the left filter chamber 5, and the waste water flows in from the top of the box body 1, and is filtered by the filter mesh 25. The sludge in the waste water leaks from the filter mesh 25 into the left filter chamber 5, while the larger particles of waste residue in the waste water remain on the filter mesh 25. After the waste water has been filtered for a period of time, the waste residue will be concentrated on the filter mesh 25 between the two adjacent partition rods 26, and then the water in the left filter chamber 5 will be precipitated, and the sludge will be precipitated to the bottom of the left filter chamber 5. The electric telescopic rod 12 is started, and the electric telescopic rod 12 extends forward, and then drives the supporting crossbeam 8 to move forward, and the supporting crossbeam 8 pulls the elastic rope 24 to extend, thereby increasing the distance between the two adjacent partition rods 26, and also pulls the filter screen 25, so that the mesh diameter of the filter screen 25 is increased, and the filter screen 25 is prevented from being blocked. At the same time, the rear end of the connecting rod I and the front end of the connecting rod III swing to the right and push the connecting rod II to move to the right side of the left filter chamber 5. During the movement of the slag lever 18 from left to right, the waste residue left on the filter screen 25 is pushed into the right slag collecting chamber 6. While the supporting crossbeam 8 pulls the elastic rope 24 to extend, the partition rod 26 is also driven forward by the elastic rope 24, and the middle partition rod 26 drives the mud paddle 27 below to move forward, thereby pushing the sludge settled in the left filter chamber 5 forward. Then the electric telescopic rod 12 retracts backwards, causing the slag lever 18 to move from right to left, and the mud paddle 27 pushes the sludge deposited in the left filter chamber 5 backwards, reducing the accumulation of sludge in the left filter chamber 5. The sludge can be discharged from the sludge discharge port 3, the waste residue is discharged from the residue discharge port 4, and the relatively clean water after filtration is discharged from the drain port 2.

[0023] Example 2: Figure 3 , 5As shown in Figures 6 and 7, a long strip-shaped support strip 16 is arranged above the right slag collecting chamber 6, and a tilting rod 17 extending obliquely to the front and above is rotatably connected to the middle of the support strip 16, and the middle of the tilting rod 17 is rotatably connected to the right side wall of the box body 1 through a rotating shaft 21, and a guide groove 19 extending along the central axis of the tilting rod 17 is opened at the front of the tilting rod 17, and a sliding limit rod 20 slidably embedded in the guide groove 19 is connected to the end of the support cross bar 14, and a plurality of elastic scraper rods 23 that can contact the slag removal rod 18 during the lifting process of the support strip 16 are connected to the left side of the support strip 16. A limit slot is vertically arranged on the right inner wall of the box body 1, and a connecting seat 22 is arranged in the middle of the support strip 16, and the rotating shaft 21 movably passes through the connecting plate and the rear end of the tilting rod 17 and extends into the limit slot.

[0024] When the electric telescopic rod 12 is extended forward, the supporting cross bar 14 moves forward and causes the sliding limit rod 20 to slide forward along the guide groove 19, so that the tilting rod 17 swings downward around the rotating shaft 21. At the same time, the tilting rod 17 drives the supporting strip 16 to move upward. During the lifting and lowering process of the elastic scraper rod 23, it contacts and rubs with the slag remover rod 18, thereby removing the debris stuck on the slag remover rod 18, thereby improving work efficiency.

[0025] The above is only a preferred implementation of this patent. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of this patent. These improvements and substitutions should also be regarded as the scope of protection of this patent.
