[0027] Reference Figures 1 to 7 A mud interception treatment device with an extendable mud interception member cleaning interval according to a preferred embodiment of the present application will be described in detail below, which comprises a device main body 10, a chemical liquid mixing assembly 20 and a mud interception treatment assembly 30, wherein the chemical liquid mixing assembly 20 and the mud interception treatment assembly 30 are both installed on the device main body 10.

[0028] The device main body 10 forms a mud interception space 101, which is connected to the outside to introduce sewage. The mud interception treatment assembly 30 comprises a first mud interception member 31, which is installed in the mud interception space 101, and the first mud interception member 31 divides the mud interception space 101 into a part close to the inlet and a part away from the inlet, and the first mud interception member 31 forms a plurality of holes of predetermined size to allow the sewage introduced into the mud interception space 101 to be intercepted and removed after passing through the first mud interception member 31 to complete the preliminary treatment of the sewage.

[0029] As an example, the first mud interception member 31 is implemented to include a grating plate.

[0030] The chemical liquid mixing assembly 20 comprises a sewage driving member 21, at least one chemical liquid member 22 and at least one mixing member 23, wherein the mixing member 23 forms a mixing space 2301, the sewage driving member 21 is installed in the part of the mud interception space 101 away from the inlet, and the sewage driving member 21 is connected to the mixing space 2301 of one of the mixing members 23 through a pipeline to send the preliminarily treated sewage into the mixing space 2301 of the mixing member 23. The chemical liquid member 22 is connected to the mixing space 2301 of the mixing member 23, the chemical liquid member 22 stores chemical liquid inside, and the mixing member 23 can suck the chemical liquid in the chemical liquid member 22 into the mixing space 2301 and mix it with the sewage to perform chemical treatment on the sewage.

[0031] As an example, the sewage driving member 21 is implemented to include a pump.

[0032] Preferably, the medicine liquid member 22 comprises a medicine liquid container 221 and a medicine liquid driving member 222, wherein the medicine liquid container 221 is communicated with the medicine liquid driving member 222 through a pipeline, the medicine liquid driving member 222 is communicated with the mixing space 2301 of the mixing member 23 through a pipeline, and the medicine liquid driving member 222 can drive the medicine liquid inside the medicine liquid container 221 to enter the mixing space 2301 through a pipeline, so as to avoid that the suction of the mixing member 23 is too small to suck the medicine liquid.

[0033] As an example, the medicine liquid driving member 222 is implemented to comprise a pump.

[0034] The device main body 10 further forms a treatment space 102. The cutting mud treatment assembly 30 further comprises at least two second cutting mud members 32, each of which comprises a cutting mud main body 321 and a cutting mud member 322, wherein the cutting mud main body 311 has an overflow space 32101, the cutting mud member 322 is installed in the overflow space 32101, and the cutting mud member 322 forms a cutting mud space 32201 and a plurality of filter holes 32202 communicated with the cutting mud space 32201. The cutting mud space 32201 is communicated with the overflow space 32101 through a plurality of filter holes 32202, and the sizes of the filter holes 32202 on the cutting mud member 322 of each second cutting mud member 32 are different.

The overflow space 32101 of the second cutting mud member 32 with the smallest size of the filter hole 32202 is communicated with the treatment space 102.

[0036] It can be understood that the sewage mixed with the liquid medicine in the mixing space 2301 of the mixing member 23 flows into the sedimentation space 32201 of the sedimentation member 322 with the largest size of the filter hole 32202, and enters the sedimentation space 32201 of the sedimentation member 322 with a slightly smaller size of the filter hole 32202 through the overflow space 32101 under the sedimentation of the sedimentation member 322, and then enters the second sedimentation member 32 with a smaller size of the filter hole 32202 through the overflow space 32101 of the second sedimentation body 321 under the sedimentation of the second sedimentation member 322, and so on, until the sewage enters the sedimentation member 322 with the smallest size of the filter hole 32202 and enters the treatment space 102 through the overflow space 32101 after filtration, completing further treatment of the sewage. In this way, the dirt to be intercepted by each sedimentation member 322 becomes less, the time required for the filter hole 32202 on the sedimentation member 322 to be through to be blocked also becomes longer, and the time interval required for the sedimentation member 322 to be flushed also becomes longer, enhancing the interception effect while reducing the flushing frequency of the sedimentation member 322.

[0037] Preferably, the sedimentation treatment device capable of extending the cleaning interval of the sedimentation member further comprises at least one flushing assembly 40, the flushing assembly 40 comprising a flushing member 41 and at least one base 42, wherein the base 42 is mounted on the device body 10. The upper end of the sedimentation body 321 communicating with the treatment space 102 is connected to the mixing space 2301 of the mixing member 23 through a pipeline, and the lower end of the sedimentation body 321 is detachably connected to the base 42. The flushing member 41 is mounted on the pipeline communicating the treatment space 102 and the overflow space 32101, and the flushing member 41 communicates the overflow space 32101 and the treatment space 102, and the flushing member 41 can flush the sewage in the treatment space 102 to the overflow space 32101 to flush the side wall of the sedimentation member 322.

[0038] As an example, the flushing member 41 is implemented to comprise a negative pressure pump.

[0039] It can be understood that when the second sludge cutting member 32 is performing the filtering operation, the flushing member 41 guides the sewage in the sludge cutting body 321 communicating with the processing space 102 to flow into the processing space 102; in the case that the filter hole 32202 is blocked by dirt inside the sludge cutting member 322, the operator can loosen the connection between the lower end of the sludge cutting body 321 and the base 42, at this time, the flushing member 41 back-flushes the sewage into the overflow space 32101, and then the sewage from the overflow space 32101 impacts the blocked filter hole 32202, so that the sludge cutting member 322 vibrates and reduces the dirt on the inner wall of the sludge cutting member 322, thereby making the filter hole 32202 no longer blocked, prolonging the service life of the sludge cutting member 322, and reducing the number of flushing the sludge cutting member 322 in the same period of time.

[0040] Preferably, the number of the second sludge cutting members 32 is three. The upper end of the sludge cutting member 322 of the second sludge cutting member 32 with the largest size of the filter hole 32202 is arranged to be communicated with the mixing space 2301 through a pipeline, and the lower end of the sludge cutting body 321 is communicated with the sludge space 32201 of the sludge cutting member 322 of the second sludge cutting member 32 with the medium size of the filter hole 32202 through a pipeline. The lower end of the sludge cutting body 321 of the second sludge cutting member 32 with the smallest size of the filter hole 32202 is arranged to be communicated with the processing space 102 through a pipeline, and the upper end of the sludge cutting member 322 is communicated with the sludge cutting body 321 of the second sludge cutting member 32 with the medium size of the filter hole 32202 through a pipeline. In this way, without reducing the filtering effect, the sewage from the bottom of the overflow space 32101 impacts the sludge cutting member 322 upwards, avoiding the dirt deposited at the bottom of the sludge cutting member 322.

[0041] It is worth mentioning that since the plurality of second sludge cutting members 32 are in a communicating relationship, when the flushing assembly 40 performs the back-flushing operation, the sewage may be flushed from the sludge cutting member 322 communicating with the processing space 102 to the sludge cutting member 322 inside other sludge cutting bodies 321, thereby prolonging the service life of all the sludge cutting members 322.

[0042] Preferably, the number of the bases 42 is equal to the number of the second strainer members 32, and the lower end of the strainer body 321 of each of the second strainer members 32 is installed on one of the bases 42, so that all the strainer bodies 321 can be separated from the bases 42 by rotation, and all the second strainer members 32 can be shaken under the impact effect of the flushing assembly 40, so that all the filter holes 32202 inside the strainer members 322 can be flushed open by shaking and the impact of sewage.

[0043] For example, the end wall of the strainer body 321 is formed with external threads, the inside of the base 42 is formed with internal threads, the strainer body 321 is screwed to the base 42, and when the strainer body 321 is rotated away from the base 42, the strainer body 321 is loosened and can be shaken.

[0044] It is worth mentioning that the pipes connected to the strainer body 321 are all flexible, which avoids the difficulty of rotating the strainer body 321, and the position of the pipes between the flushing assembly 40 and the strainer body 321 is also designed to facilitate rotation, but if the angle of rotation of the strainer body 321 is not large enough, the strainer body 321 and the base 42 are still in a fixed connection state, which can affect the impact effect of the flushing assembly 40.

[0045] Therefore, as a preferred embodiment, the base 42 comprises a base body 421 and a movable member 422, wherein the base body 421 is fixed to the device body 10. The movable member 422 is annular, the outer wall of the movable member 422 is screwed to the base body 421, and the inner wall of the movable member 422 is screwed to the strainer body 321. The operator can rotate the movable member 422 to separate the strainer body 321 and the base body 421, and because the movable member 422 and the strainer body 321 are screwed, the strainer body 321 can be loosened from the base body 421 without rotation, so that the pipe connection position on the strainer body 321 does not need to be specially designed, and the pipe does not affect the connection between the strainer body 321 and the base body 421.

[0046] Preferably, the flushing assembly 40 further comprises at least one buffering member 43, which comprises a joint body 431, at least one pair of buffering pieces 432 and at least one mounting piece 433, wherein the joint body 431 is arranged around the communication pipe of the cutting body 321, and the joint body 431 is formed with at least two pairs of buffering holes 43101 in the vertical direction. Each pair of the buffering pieces 432 is arranged to be mounted in a pair of the buffering holes 43101, and each of the mounting pieces 433 is fixed to the equipment body 10 through a pair of the buffering pieces 432. In this way, the joint body 431 and the mounting piece 433 are abutted by the buffering pieces 432 in the transverse direction, and since the mounting piece 433 is fixed, when the cutting body 321 vibrates, the joint body 431 is driven to vibrate and press against the buffering pieces 432, so as to offset part of the vibration force under the buffering effect of the buffering pieces 432, thereby limiting the vibration of the upper end of the cutting body 321, and avoiding excessive vibration of the cutting body 321 to cause water leakage.

[0047] For example, the buffering pieces 432 are implemented to comprise spherical springs.

[0048] Preferably, the number of the buffering members 43 is implemented to be the same as the number of the second cutting members 32, and each of the buffering members 43 is mounted around the communication pipe of the upper end of the cutting body 321, so that all the cutting bodies 321 offset part of the vibration force under the buffering effect of the buffering members 43, thereby avoiding excessive vibration of the cutting bodies 321 to cause water leakage.

[0049] Preferably, the mounting piece 433 comprises a mounting body 4331, a mounting auxiliary body 4332 and a pair of fixing pins 4333, wherein the mounting body 4331 and the mounting auxiliary body 4332 are arranged on the upper and lower sides of a pair of the buffering holes 43101 of the joint body 431 respectively, and the mounting body 4331 is fixed to the equipment body 10. Each of the fixing pins 4333 passes through the mounting body 4331, the mounting auxiliary body 4332 and a buffering hole 43101, so that the joint body 431 is clamped by the mounting piece 433 to avoid separation of the joint body 431 from the mounting piece 433.

[0050] Preferably, the mixing member 23 comprises a mixing body 231 and a stirring member 232, wherein the mixing space 2301 is formed by the mixing body 231, and the mixing space 2301 is communicated with the interior of the liquid member 22 and the pipeline communicated with the sewage driving member 21. The stirring member 232 is installed in the mixing space 2301 of the mixing body 231, and the stirring member 232 can rotate spirally and push the sewage and the liquid in the mixing space 2301 after stirring.

[0051] As an example, the stirring member 232 is implemented to comprise a rotatable spiral blade.

[0052] It can be understood that when the stirring member 232 rotates, the liquid in the mixing space 2301 is pushed to the second dewatering member 32, at this time, negative pressure is generated in the interior of the mixing space 2301, and because the interior of the liquid member 22 is communicated with the mixing space 2301, the liquid in the interior of the liquid member 22 can enter the mixing space 2301 and mix with the sewage due to the rotation of the stirring member 232, and at the same time, enter the second dewatering member 32 under the pushing of the stirring member 232.

[0053] Preferably, the number of the liquid member 22 is implemented to be at least two, and the plurality of liquid members 22 are all communicated with the mixing space 2301 of one mixing body 231, and the liquid in the interior of the plurality of liquid members 22 can be set to be different in composition, so that different liquids can be mixed in the mixing space 2301 to treat the sewage.

[0054] Preferably, the number of the mixing member 23 is implemented to be the same as the number of the liquid member 22, each liquid member 22 is communicated with the mixing space 2301 of one mixing body 231, and the mixing spaces 2301 of the adjacent two mixing bodies 231 are communicated. In this way, different liquids can be mixed with the sewage in sequence, which is convenient for the use of some liquids.

[0055] Preferably, the dewatering treatment equipment with an extendable dewatering member cleaning interval further comprises a treatment member 50, the treatment member 50 is installed in the treatment space 102, and the treatment member 50 can further treat the sewage filtered by the second dewatering member 32.
