Description

Technical Field

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

[0002] The sludge thickener is mainly used for sludge with a concentration of 1% or less than 1%, to increase its solid content, that is, the sludge concentration. After being concentrated by the sludge thickener, the outflow concentration is above 3%, which is convenient for subsequent mechanical dehydration and improves the efficiency and use effect of mechanical dehydration. The sludge thickener is a central transmission continuous or intermittent working thickening and clarification equipment. The sludge thickener is mainly used in water treatment systems such as blast furnaces, continuous casting, hot rolling and water plants in the metallurgical industry, or for the concentration or purification of all solid-containing slurries in industries such as coal, chemical industry, building materials, water sources, and sewage treatment. It can also be used for the concentration and dehydration of concentrate and tailings slurries in wet mineral processing operations. The main components and features of the sludge thickener are as follows: The thickener consists of five parts: a thickening tank, a specially designed large torque water-type bridge, a main transmission mechanism, a lifting mechanism, and a slag rake.

[0003] Prior art includes a utility model with publication number CN213388291U, which discloses a sludge thickener for a sewage treatment plant. The patent adopts a sludge thickening box, wherein a drum is provided inside the sludge thickening box, and a first motor is fixedly installed at the right end outside the sludge thickening box. The output shaft of the first motor passes through the drum and is connected to one end of a conveying screw. A filter is provided at the bottom end of the drum. The sludge thickening box, the left end of the drum is connected to a second pipe body, and the other end of the second pipe body is connected to a sludge drying box. The utility model equipment solves the problem that it is difficult for the equipment to heat and dry the sludge, evaporates the residual water in the sludge, and reduces the amount of sludge processed.

[0004] In daily work, when thickening the sludge, hard objects are easily wrapped in the sludge. When the sludge enters the main body and the roller is squeezed, the hard objects are easily stuck between the roller and the main body, making it difficult for the equipment to extrude and concentrate.

[0024] In this embodiment: the filter device 6 includes a positioning block 61 and a filter frame 62, the positioning block 61 is fixedly connected to the inside of the feed hopper 3, the filter frame 62 is arranged inside the feed hopper 3, a connecting groove 64 is opened on the surface of the positioning block 61, the filter frame 62 is clamped with the inside of the connecting groove 64, a filter net 63 is fixedly connected to the inside of the filter frame 62, and a positioning rod 65 is fixedly connected to the inside of the connecting groove 64.

[0025] Specifically, the positioning rod 65 is slidably connected to the inside of the filter frame 62 , and a first connecting ring 66 is sleeved and connected to the surface of the positioning rod 65 .

[0026] In this embodiment, by setting a positioning rod 65, the filter frame 62 can be limited, which reduces the situation where the filter frame 62 shakes on the inner wall of the hopper 3 when the equipment is in use, making it difficult for the filter frame 62 to filter the sludge.

The nut 69 is provided to facilitate limiting the second connecting ring 67.

[0033] Working principle: When the equipment is in use, the user passes the sludge to be concentrated into the feeder 2 through the feed hopper 3, and then starts the equipment. The sludge is squeezed and concentrated through the roller 4 inside the main body 1, and discharged through the discharger 5.
