Technical Field

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

[0002] The sludge generated during the wastewater treatment process has a high water content, so the volume of the sludge is relatively large, which makes it difficult to handle, utilize and transport the sludge. Sludge concentration is to reduce the water content and volume of the sludge by thickening the sludge, thereby reducing the subsequent treatment costs. In the prior art, when the sludge is treated by centrifugation, it is easy to stick to the centrifuge cylinder and block the centrifuge cylinder. When cleaning, the treatment work needs to be stopped. In this way, the treatment efficiency is reduced, and the centrifuge cylinder cannot be cleaned during the sludge concentration treatment, which is inconvenient to use.

[0003] For example, patent application number CN202311564530.4 belongs to the field of sludge treatment technology, especially a sludge concentration device for sewage treatment plants. The invention can throw out the sewage in the sludge through the centrifugal force of the rotating filter cylinder, and squeeze the sludge by rotating the downward push block, so as to accelerate the dehydration and concentration of the sludge. When in use, the centrifugal cylinder cannot be cleaned during the sludge concentration process, which is inconvenient to use. Problem.

[0004] For example, patent application number CN202322005955.3 discloses a sewage treatment sludge concentration device, which improves the gravity concentration efficiency of the sludge at the bottom of the conical cylinder, improves the overall sludge concentration efficiency, and also facilitates the discharge of sludge from the sludge discharge pipe.

Obviously, the described embodiments are only 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.

[0024] See also Figure 1-5 The utility model provides a technical solution: a sludge concentration treatment device for sewage treatment, comprising a shell 1, grooves 3 are arranged on both sides of the top of the shell 1, and a treatment mechanism 2 is arranged inside the shell 1.

[0025] The processing mechanism 2 includes a centrifugal cylinder 201, a circular plate 202 is arranged inside the bottom end of the centrifugal cylinder 201, a telescopic rod 203 is arranged on the top of the circular plate 202, a motor 204 is arranged on the top of the telescopic rod 203, a hole 205 is arranged on the surface of the centrifugal cylinder 201, an annular plate 206 is arranged on the outer side of the top of the centrifugal cylinder 201, a support plate 207 is arranged at the bottom of the annular plate 206, and the cross-sectional shape of the support plate 207 is L-shaped, a circular ring 208 is arranged inside the outer shell 1, a push plate 209 is arranged on the inner wall of the circular ring 208, and the push plate 209 is inclined near the inner wall of the centrifugal cylinder 201, a ball 210 is arranged above the circular ring 208, and a cleaning rod 211 is fixedly arranged on one side of the ball 210.

[0026] A blocking plate 212 is provided at the top of the centrifugal cylinder 201 . There are two blocking plates 212 , and both blocking plates 212 are in contact with the telescopic rod 203 .

[0027] The two blocking plates 212 are fixedly connected to the annular plate 206 by screws, the number of cleaning rods 211, balls 210 and holes 205 is equal, each cleaning rod 211 is aligned with each hole 205, the holes 205 are inclined, a sleeve 213 is provided at the bottom of the centrifugal cylinder 201, and an electric push rod 214 is provided inside the sleeve 213.

[0028] See also Figure 2-4 An electric hydraulic rod 215 is disposed above the circular ring 208 , and a push rod 216 is disposed at the bottom of the electric hydraulic rod 215 . The cross-sectional shape of the push rod 216 is L-shaped.

[0029] A lifting rod 217 is provided on the top of the annular plate 206, the top of the lifting rod 217 is located at the top of the groove 3, the width of the lifting rod 217 is adapted to the groove 3, the lifting rod 217 is fixedly connected to the housing 1 by screws, and the motor 204 is fixedly connected to the housing 1 by a bracket.

[0030] During operation, the sludge is placed in the centrifugal cylinder 201 and falls on the circular plate 202. Then, the plugging plate 212 is combined with the centrifugal cylinder 201 and fixed by screws, which improves the stability of the plugging plate 212 and facilitates subsequent operations. Then, the motor 204 is used. Since the output shaft end of the motor 204 is connected to the telescopic rod 203, the telescopic rod 203 is driven by the motor 204 to rotate, and the circular plate 202 fixedly connected to the telescopic rod 203 rotates at the same time. Since the circular plate 202 is movably connected to the centrifugal cylinder 201, the circular plate 202 can be moved up and down later. When the circular plate 202 rotates, the centrifugal cylinder 201 rotates at the same time, and the sludge is processed by centrifugation. At this time, the screws at the lifting plate are first removed, and the electric push rod 214 is used to move the lifting plate downward, so that the lifting plate enters the groove 3 and moves downward in the groove 3. The movement of the lifting plate allows the annular plate 206 to move downward at the same time, and the position of the annular plate 206 is adjusted. Since the annular plate 206 is fixedly connected to the support plate 207, the support plate 207 moves downward at the same time, and the downward movement of the support plate 207 can be adjusted with the push rod 214. The movable plate 209 is separated. After separation, under the action of gravity, the annular plate 206 and the circular ring 208 move downward at the same time, so that the annular plate 206 moves downward together with the circular ring 208, and the annular plate 206 moves to the bottom of the centrifugal cylinder 201, which is convenient for subsequent operations. After that, the stability of the annular plate 206 is improved again by screws, and subsequent operations can be performed. The electric push rod 214 is used to move the circular plate 202 upward through the electric push rod 214, so that the circular plate 202 moves upward in a straight line, and the sludge on the circular plate 202 is pushed into the top of the centrifugal cylinder 201. The electric hydraulic rod 215 is then used to move the ring 208 upward, so that the push plate 209 on the inner wall of the ring 208 moves upward at the same time. Through the upward movement of the push plate 209, since the push plate 209 is inclined close to the inner wall of the centrifugal cylinder 201, the ball 210 can be pushed to move, so that the cleaning rod 211 gradually enters the hole 205, and the hole 205 can be cleaned to prevent the hole 205 from being blocked, which is convenient for subsequent operations. In the process of cleaning, the sludge can be processed on it without affecting the processing, and it is easy to use.
