[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are 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. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the utility model.

[0024] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0025] At the outlet of the existing dehydrator, a back pressure plate is installed to block the sludge at the end so that it can be more fully concentrated. When the material is discharged into the guide trough, there is still water, which causes the sludge to hang on the surface wall of the guide trough. When it continues to work, it will directly become sticky and it is very inconvenient to clean it later. Therefore, in order to solve the above problems, this case proposes the following technical solutions:

[0026] Reference Figure 1 to Figure 4As shown, a high-efficiency sludge thickening device includes: a dosing tank 5, which is fixedly connected to an inlet 6, a stirrer 7 is installed on the top of the dosing tank 5, and a stirring shaft of the stirrer 7 extends to the inside of the dosing tank 5. The dosing tank 5 is also installed in a first machine chamber 3 inside a filter element 2 through a pipeline, the filter element 2 is installed on the top of a second machine chamber 4 and the bottom hole of the filter element 2 is communicated with the inner cavity of the second machine chamber 4, a discharger 1 is installed at the front end of the filter element 2, and a movable guide seat 13 is provided at the bottom of the discharger 1, and the guide seat 13 is connected to the partition chamber 14 and fixed to the surface of the filter element 2 through the partition chamber 14.

[0027] The main structure of the device includes an inlet 6, which is installed on the side of the dosing tank 5 and communicates with the inner cavity of the dosing tank 5. The inlet 6 is used to connect the sewage pipe. A stirrer 7 for stirring and mixing flocculants and sewage is installed on the top of the dosing tank 5. After the flocculants are added, impurities inside the sewage are precipitated. The precipitated solid-liquid mixture enters the first chamber 3 through the pipeline connected between the dosing tank 5 and the first chamber 3 for concentration until the solid and liquid are separated.

[0028] The first machine chamber 3 is composed of a plurality of filter plates. The gaps between the filter plates gradually decrease along the slope, making the concentration more thorough. The paging liquid flows into the second machine chamber 4 through the bottom of the filter element 2 installed in the first machine chamber 3 for recovery. A rotating screw is installed inside the first machine chamber 3. The rotating screw is driven by the reducer 12 driven by the driver 11 of the discharger 1. The continuously rotating screw gradually lifts the separated material upward and then pushes it out from the position of the back pressure plate 15 and falls into the surface of the guide seat 13 and is transported to the recovery tank.

[0029] In order to better observe the working state of the back pressure plate 15, the surface of the partition 14 is provided with grooves, the depth of which is less than 1 / 3 of the side of the partition 14, so as to reduce the ejection of squeezed sludge from the side while enabling observation.

[0030] The conventional guide seat 13 is usually a stainless steel guide plate structure, but due to the stickiness of the sludge itself, it is easy to stick to the surface of the guide plate 135, thereby causing the sludge to fall out from both sides and affecting the collection effect.

[0031] The device is improved in that the roller body 139 installed between the loading support side plates 132 is driven to rotate by the second driver 133. When the roller body 139 rotates, it drives the cleaning belt 134 to move. During the movement of the cleaning belt 134, the cross plate and the surface of the guide plate 135 rub against each other, cutting the surface of the guide plate 135 to separate the mud blocks.

[0032] In order to prevent the cleaning belt 134 from randomly dropping mud and debris when passing through the bottom of the guide plate 135 , the mud and debris are collected at the bottom of the guide plate 135 through the bottom groove 131 , and the dropped debris rolls along the inner wall of the bottom groove 131 .

[0033] At the same time, in order to further reduce the sticking of mud on the surface of the cleaning belt 134, a brush plate 138 is installed inside the bottom groove 131 to clean the cross plate of the cleaning belt 134. There is a gap between the brush plate 138 and the bottom surface of the bottom groove 131 to avoid obstruction and facilitate the rolling of debris.

[0034] A second driver 133 is installed on one side of the supporting side plate 132 for driving the roller body 139 to rotate, and a movable ear 136 is set on one side to nest with the cylindrical connection point raised on the side of the partition 14, and to facilitate the adjustment of the elevation angle of the guide plate 135. An adjustment handle 137 is installed on the side of the movable ear 136 for locking, and the stud of the adjustment handle 137 cooperates with the threaded hole of the movable ear 136. When rotating, it presses the cylinder on the side of the partition 14 to achieve limiting.

[0035] The improved device drives the roller body 139 to rotate through the second driver 133, driving the cleaning belt 134 to rotate. The scraper bar installed axially along the roller body 139 on the surface of the cleaning belt 134 rubs against the guide plate 135 during operation. The triangular column-shaped scraper bar cuts the sludge blocks to make them fall off better, reducing the stickiness on the surface of the guide plate 135 and making it more concentrated during transportation.

[0036] In order to prevent sludge debris from falling into the working area, a bottom groove 131 is provided on the top of the guide plate 135 for guiding secondary recovery, and the scraper strip of the cleaning belt 134 is cleaned by a brush plate 138 to improve the cleaning effect.

[0037] The above only describes the basic principles and preferred implementations of the present utility model. Those skilled in the art can make many changes and improvements based on the above description, and these changes and improvements should fall within the protection scope of the present utility model.

[0038] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
