Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, in particular to a sludge receiving tank for sludge treatment. Background Art

[0002] Sludge is a product after sewage treatment, a thick substance between liquid and solid, which can be transported by pumps. However, when sludge is stored in a receiving tank, it is very easy to deposit and agglomerate, which is not conducive to the subsequent pumping operation. There are currently two solutions to this problem:

[0003] 1. Install a scraper to scrape the sludge out. However, after the sludge has settled, it is difficult for the scraper to scrape it.

[0004] 2. Install a stirring structure to continuously stir the sludge. However, the sludge cannot be completely pumped out later. Summary of the Invention

[0005] Aiming at the deficiencies of the above-mentioned prior art, the technical problem to be solved by this patent application is how to provide a sludge receiving tank for sludge treatment that can stir the sludge, scrape the sludge, and facilitate pumping.

[0006] To solve the above technical problem, the utility model adopts the following technical scheme:

[0007] A sludge receiving tank for sludge treatment includes a tank body. The tank body has a sludge chamber with an upper opening. A sludge outlet is opened at the lower part of one end of the tank body, and a valve is installed at the sludge outlet.

[0008] Lifting structures for driving a stirring structure to move up and down are installed at both ends of the tank body, and the stirring structure is arranged opposite to the sludge chamber. A scraper is slidably fitted in the tank body, and scraper moving structures for driving the scraper to move are installed on both sides of the tank body.

[0009] In this way, when the sludge reaches the receiving tank, the lifting structure drives the stirring structure to reach the sludge chamber, and the stirring structure stirs the sludge to prevent the sludge from settling and agglomerating. When it is necessary to pump out the sludge, the valve at the sludge outlet is opened, the lifting structure drives the stirring structure to move above the sludge chamber, the scraper moving structure drives the scraper to move, and the scraper drives the sludge to move towards the sludge outlet, facilitating the pumping of the sludge. After the sludge pumping is completed, the scraper returns to its original position, and the stirring structure returns to its original position.

[0010] Among them, the stirring structure includes a stirring shaft. Stirring rods are circumferentially and evenly arranged on the outer side of the stirring shaft. A plurality of connecting rings are sleeved on the outer side of the stirring shaft. The connecting rings are fixedly connected to the stirring shaft through a plurality of connecting rods, and the stirring rods are fixedly connected to the connecting rings.

[0011] Both ends of the stirring shaft are respectively connected to the connecting plate through bearings. A servo motor is fixedly installed on one of the connecting plates through a motor bracket. The output shaft of the servo motor passes through the connecting plate and is fixed with a driving pulley. One end of the stirring shaft facing the driving pulley is fixedly installed with a driven pulley. The driving pulley and the driven pulley are connected by a belt.

[0012] Among them, the lifting structure includes two lifting frames. The connecting plate is fixedly connected to the lifting frame. Both ends of the lifting frame are fixedly connected to the cylinder rods of the lifting cylinders. The lifting cylinders are fixedly installed outside the pool body.

[0013] Among them, the connecting plate is in a T shape.

[0014] Among them, the scraper moving structure includes a linear module fixedly installed outside the pool body. The upper end of the scraper protrudes outward to form a convex edge. The slider of the linear module is fixedly connected to the convex edge.

[0015] In summary, the sludge receiving pool for sludge treatment of the present invention has the advantages of being able to stir the sludge, scrape the sludge, and facilitate pumping out. Description of the Drawings

In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the orientation words such as "upper, lower" and "top, bottom" is usually based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, so they cannot be understood as limiting the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0020] As Figures 1 - 3 shown, a sludge receiving pool for sludge treatment includes a pool body 1. The pool body has a sludge chamber with an open upper end. A sludge outlet 2 is opened at the lower part of one end of the pool body. A valve 3 is installed at the sludge outlet.

[0021] Lifting structures for driving the stirring structure to move up and down are installed at both ends of the pool body, and the stirring structure is arranged facing the sludge chamber; a scraper 4 is slidably fitted in the pool body, and scraper moving structures for driving the scraper to move are installed on both sides of the pool body.

[0022] In this way, when the sludge reaches the receiving pool, the lifting structure drives the stirring structure to reach the sludge chamber, and the stirring structure stirs the sludge to prevent the sludge from settling and caking. When it is necessary to pump out the sludge, the valve at the sludge outlet is opened, the lifting structure drives the stirring structure to move above the sludge chamber, the scraper moving structure drives the scraper to move, and the scraper drives the sludge to move towards the sludge outlet, facilitating the pumping out of the sludge. After the sludge pumping is completed, the scraper returns to its original position, and the stirring structure returns to its original position.

[0023] Through the cooperation of the stirring structure and the scraper, the sludge can be better contained.

[0024] During implementation, the stirring structure includes a stirring shaft 5. Stirring rods 6 are circumferentially and evenly arranged on the outer side of the stirring shaft. A number of connecting rings 7 are sleeved on the outer side of the stirring shaft. The connecting rings are fixedly connected to the stirring shaft through a number of connecting rods 8, and the stirring rods are fixedly connected to the connecting rings;

[0025] Both ends of the stirring shaft are respectively connected to a connecting plate 9 through bearings. A servo motor 10 is fixedly installed on one of the connecting plates through a motor bracket. The output shaft of the servo motor passes through the connecting plate and is fixed with a driving pulley 11. A driven pulley 12 is fixedly installed at one end of the stirring shaft facing the driving pulley, and the driving pulley and the driven pulley are connected by a belt 13.

[0026] In this way, the servo motor drives the driving pulley to rotate, drives the stirring shaft to rotate through the belt and the driven pulley, and then drives the stirring rods to rotate to stir the sludge.

[0027] During implementation, the lifting structure includes two lifting frames 14. The connecting plate is fixedly connected to the lifting frames. Both ends of the lifting frames are fixedly connected to the piston rods of lifting cylinders 15. The lifting cylinders are fixedly installed outside the pool body. The lifting cylinders drive the lifting frames to move up and down, realizing the lifting of the stirring structure.

[0028] During implementation, the connecting plate is in a T shape. It can better save materials and reduce costs.

[0029] During implementation, the scraper moving structure includes a linear module 16 fixedly installed outside the pool body. The upper end of the scraper protrudes outward to form a convex edge, and the slider of the linear module is fixedly connected to the convex edge. The linear module drives the scraper to move, which is convenient for use.
