[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] like Figure 1-Figure 4 As shown, the utility model provides a sludge thickening separator, including a base 1, a separator body 5 is fixedly connected to the top of the base 1, a separator screen basket 12 is arranged inside the separator body 5, a high-pressure gas injection device 13 is arranged at the top of the inner part of the separator screen basket 12, the top of the high-pressure gas injection device 13 is connected to a first conveying pipe 6, one end of the side of the first conveying pipe 6 is connected to an air pump 16, and the bottom of the air pump 16 is connected to a high-pressure gas generating device 15.

[0023] A motor 7 is arranged on the top of the separator body 5, and the output end of the motor 7 is fixedly connected to the top of the separator screen basket 12. The top of the separator body 5 is connected to a fourth conveying pipe 17, and one end of the side of the fourth conveying pipe 17 is connected to a sludge pump 4. The bottom of the sludge pump 4 is connected to a feed pipe 3, and a blocking plate 18 is arranged on the inner surface wall of the separator body 5.

[0024] In this embodiment, the sludge pump 4 is first started, and the sludge is sucked in by the cooperation of the feed pipe 3. Then, the sludge can enter the interior of the separator body 5 through the action of the fourth conveying pipe 17, so as to facilitate the subsequent solid-liquid separation operation. Then, the motor 7 is started to drive the separator screen basket 12 inside the separator body 5 to rotate, and the sludge is subjected to solid-liquid separation operation. When the water inside the sludge is separated, it will flow out through the pores on the surface of the separator screen basket 12 and reach the bottom end of the separator body 5, and the remaining solid part of the sludge will be attached due to centrifugal force. The inner wall of the separator screen basket 12 moves upward due to its accumulation, and then the sludge is discharged to the top of the separator body 5 through the separator screen basket 12. Under the action of the blocking plate 18, the solid part of the sludge is separated at the top of the separator body 5 so that it will not fall, causing secondary pollution to the water in the sludge, and improving the separation efficiency.

[0025] Since the solid part of the sludge is sticky, it will adhere to the top of the separator sieve basket 12, resulting in reduced discharge efficiency of the solid part of the sludge. Therefore, the high-pressure gas generating device 15 is started to generate high-pressure gas, and then the air pump 16 is started to pump the high-pressure gas into the high-pressure gas injection device 13. The high-pressure gas injection device 13 is started to spray the top part of the separator sieve basket 12 to clear blockage on the top of the separator sieve basket 12, avoid blockage on the top of the separator sieve basket 12, and affect the discharge of the solid part of the sludge, thereby improving the separation efficiency.

[0026] The bottom of the sludge pump 4 is fixedly connected to four supporting legs 11, the bottom of the feed pipe 3 is fixedly connected to a fixed block 2, the outer wall of the separator body 5 is connected to the second delivery pipe 8, one end of the side of the second delivery pipe 8 is connected to a sludge collection box 9, the outer wall of the separator body 5 is connected to the third delivery pipe 14, one end of the side of the third delivery pipe 14 is connected to a sewage collection box 10.

[0027] In this embodiment, the sludge pump 4 can be supported by the support legs 11, ensuring the stable operation of the sludge pump 4 and improving its working efficiency. The feed pipe 3 can be supported by the fixed block 2, improving its load-bearing capacity and extending its service life. Then, under the action of the second conveying pipe 8, when the solid part of the sludge reaches the top of the separator body 5, the squeezing force generated by the sludge accumulation allows the solid part of the sludge to pass through the second conveying pipe 8 and reach the inside of the sludge collection box 9, which is convenient for collecting the solid part of the sludge. Then, under the action of the third conveying pipe 14, when the water in the sludge flows to the bottom of the separator body 5, it can reach the inside of the sewage collection box 10 through the third conveying pipe 14, which is convenient for collecting the water in the sludge, and then it is convenient to separate the solid part of the sludge from the water, improve the separation efficiency, and reduce the quality of the sludge, which is convenient for subsequent processing operations.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
