The top cover plate and the grid plate can be quickly removed from the water inlet tank, and it is convenient to clean the impurities such as stones, so as to avoid the accumulation of impurities such as stones in the water inlet tank, causing blockage and making it impossible to continue the water inlet work. 2. The driving sleeve drives the driving tube to rotate, so that the worm at the lower end of the driving tube rotates, and the four lifting sliders on the four lifting components drive the lifting support plate to steadily descend inside the box body, and the liquid in the sewage is squeezed upward by the filter press bag. The anti-leakage frame increases the height at the bottom of the lifting support plate to prevent the sewage from leaking from the gap between the lifting support plate and the inner wall of the box body, thereby improving the effect of the sewage filtering through the filter press bag. The liquid in the sewage fully passes through the filter press bag and flows upward, while the sludge cannot pass through the filter press bag and settles inside the sinking tank, thereby accelerating the separation speed and comprehensiveness of the sludge and liquid in the sewage; 3. After the sludge and liquid are completely separated by the filter bag, the lower end of the pumping pipe descends with the descent of the lifting support plate. During the descent, the telescopic hose is pulled to extend, and the telescopic hose has a sealing and conduction effect. The sludge in the sewage is separated in the lower layer according to the lifting support plate. After separation, the liquid in the sewage is on the upper surface of the lifting support plate. At this time, the lower end of the pumping pipe is also on the upper surface of the lifting support plate. The liquid in the sewage after the sludge separation is completely extracted through the pumping pipe, avoiding the fixed height of the pumping pipe and only being able to extract the liquid above, resulting in incomplete extraction.

There are four support rods s4, and they are welded at four positions between the top cover plate s2 and the grille plate s9. The grille plate s9 is stably and horizontally installed below the top cover plate s2 through the four support rods s4, so that when the top cover plate s2 is snap-fitted and installed on the top of the water inlet tank s7, the grille plate s9 is installed into the water inlet tank s7 to preliminarily remove larger solid impurities such as stones in the sewage entering from above, and through the snap-fitting installation of the top cover plate s2 and the water inlet tank s7, the top cover plate s2 and the grille plate s9 can be quickly removed from the water inlet tank s7, and it is convenient to clean impurities such as stones, so as to avoid the accumulation of impurities such as stones in the water inlet tank s7, causing blockage and inability to continue water intake.

[0024] Among them, the separation mechanism J includes a driving mechanism j5 and a separation box j9. The driving mechanism j5 is snap-fitted and installed on the top of the separation box j9 and is transmission connected. The water inlet tank s7 is installed above the front end of the separation box j9, and the rear end of the water inlet tank s7 is connected to the inside of the separation mechanism J through the water inlet groove s1. Support feet Z are welded at the four corners of the bottom of the separation mechanism J.

[0025] The driving mechanism j5 includes a power box j54, a clamping plate j58, a driving sleeve j56, and a plug-in rod j51. The bottom of the power box j54 is fixedly installed with a clamping plate j58, and the bottom of the power box j54 is clamped and installed on the upper end of the separation box j9 through the clamping plate j58. The driving sleeve j56 is installed inside the clamping plate j58 with a clearance fit, and a plug-in rod j51 is provided in the center of the driving sleeve j56. The upper end of the driving sleeve j56 is transmission-connected with the power box j54. The size of the snap plate j58 is consistent with the size of the cavity inside the upper end of the separation box j9. By snapping the snap plate j58 into the upper end of the separation box j9, the power box j54 can be quickly installed on the upper end of the separation box j9 for quick disassembly and assembly.

The power box j54 can synchronously drive the four drive sleeves j56 and the plug-in rod j51 to rotate, and the four drive sleeves j56 and the plug-in rod j51 can synchronously drive the separation box j9 to operate, thereby improving the synchronous stability of the overall operation inside the separation box j9.

[0026] The power box j54 includes a housing 4k, a motor 4d, a driving belt 4p, a driving wheel 4q, a driven belt 4s, and a transmission wheel 4c. The bottom of the housing 4k is mounted on the upper end of the separation box j9 through a clamping plate j58, and the motor 4d is fixedly mounted on the top middle end of the housing 4k. The motor 4d is connected to the driving wheel 4q through a driving belt 4p, and the outer side of the driving wheel 4q is connected to the driven belt 4s.

The four driving wheels 4q are connected for synchronous rotation through the driven belt 4s, and the driven belt 4s is squeezed and transmitted through four transmission wheels 4c to enhance the tightness of the driven belt 4s, ensuring that when one of the driving wheels 4q rotates, it can drive the other three driving wheels 4q to rotate through the driven belt 4s, so that when the motor 4d is running, the four driving wheels 4q run synchronously to drive the four driving sleeves j56 to rotate synchronously.

[0027] The separation box j9 includes a box body j96, a water inlet pipe j92, a permeation mechanism j91, a sinking trough j97, and a mud discharge pipe j94. The bottom of the shell 4k is mounted on the upper end of the box body j96 through a clamping plate j58.

The permeation mechanism j91 is installed inside the box body j96. The top of the permeation mechanism j91 is connected to the driving sleeve j56 and rotates synchronously. A sinking trough j97 is fixedly installed at the bottom of the box body j96. The mud discharge pipe j94 is embedded on the surface of the sinking trough j97 and is connected through. The size of the cavity inside the upper end of the box j96 is consistent with the size of the snap plate j58, so that the power box j54 can be quickly disassembled and assembled at the upper end of the box j96 through the snap plate j58, which improves the convenience of disassembly and assembly and facilitates the disassembly and maintenance of the device. The top of the infiltration mechanism j91 is located in the cavity inside the upper end of the box j96, and can be socketed and connected with the four ends of the top of the infiltration mechanism j91 through four driving sleeves j56, thereby driving the infiltration mechanism j91 as a whole to operate stably inside the box j96. The specific usage and function of this embodiment are as follows: In the present invention, when the sewage is subjected to sludge separation, the external sewage is connected to the sewage inlet pipe s5, so that the sewage is discharged into the water inlet tank s7. When the sewage enters the water inlet tank s7, the larger solid impurities such as stones in the sewage are intercepted and removed by the grille plate s9, and the top cover plate s2 and the water inlet tank s7 are engaged and installed, so that the top cover plate s2 and the grille plate s9 can be quickly removed from the water inlet tank s7, and it is convenient to clean the impurities such as stones, so as to avoid the accumulation of impurities such as stones in the water inlet tank s7 and cause blockage and inability to continue water intake. The intercepted sewage enters the separation box j9 from the water inlet trough s1. When the height of the sludge in the separation box j9 reaches two-thirds, the water intake is stopped, and the motor 4d is started, and a driving wheel 4q connected to the driving belt 4p is driven to drive. At this time, the four driving wheels The 4q are connected for synchronous rotation through a driven belt 4s, and the driven belt 4s is squeezed and transmitted through four conduction wheels 4c to strengthen the tightness of the driven belt 4s, ensuring that when one of the driving wheels 4q rotates, the other three driving wheels 4q can be driven to rotate through the driven belt 4s, so that when the motor 4d is running, the four driving wheels 4q run synchronously to drive the four driving sleeves j56 to rotate synchronously, and the driving sleeves j56 are connected to the top of the infiltration mechanism j91 at the upper end of the separation box j9 in a sleeve manner, which is convenient for disassembly and maintenance, and the infiltration mechanism j91 is synchronously driven by the four driving sleeves j56 to run stably as a whole inside the box j96, and the sludge in the sewage is separated. The separated sludge is deposited in the sinking tank j97, and the separated sludge can be discharged through the sludge discharge pipe j94. Example

[0028] As attached Figure 7 To Attachment Fig. 9 As shown: Wherein, the infiltration mechanism j91 includes a lifting component 1q, a water suction pipe 1c, a telescopic hose 1s, and a filter press mechanism 1v. The top of the lifting component 1q is located inside the upper end of the box j96. The top of the lifting component 1q is sleeve-connected with the driving sleeve j56 and rotates synchronously. The lifting component 1q is inserted into the edge of the filter press mechanism 1v with a clearance fit, and the lower end of the water suction pipe 1c is fixedly installed on the upper surface of the filter press mechanism 1v. A telescopic hose 1s is installed in the middle of the water suction pipe 1c. The upper end of the water suction pipe 1c is fixedly installed on the inner wall of the box j96 and is through-connected. The filter press mechanism 1v is slidably installed inside the box j96, and the filter press mechanism 1v is located above the sinking tank j97. There are four lifting components 1q, and they are distributed at the four corners of the filter press mechanism 1v. The tops of the four lifting components 1q are respectively connected to the four driving sleeves j56 and rotate synchronously, so that the four lifting components 1q can operate synchronously to drive the filter press mechanism 1v as a whole to operate stably. The telescopic hose 1s has a pleated structure and is made of rubber material. It has good resilience and can extend the pumping pipe 1c as a whole. The lower end of the pumping pipe 1c descends with the descent of the filter press mechanism 1v, and the sludge in the sewage is separated in the lower layer according to the filter press mechanism 1v. After separation, the liquid in the sewage is in the upper layer of the filter press mechanism 1v. At this time, the lower end of the pumping pipe 1c is also in the upper layer of the filter press mechanism 1v, so that the liquid in the sewage after the sludge separation is fully extracted, avoiding the fixed height of the pumping pipe 1c and only being able to extract the liquid above, resulting in incomplete extraction.

[0029] The filter press mechanism 1v includes a lifting support plate v3, a filter press bag v9, and a leak-proof frame v6. The lifting component 1q is interlaced and penetrates the edge of the lifting support plate v3. A filter press bag v9 is provided in the middle of the lifting support plate v3. The leak-proof frame v6 is welded to the bottom edge of the lifting support plate v3. The lifting support plate v3 is slidably installed inside the box body j96. The lifting support plate v3 and the filter press bag v9 are located above the sinking tank j97. The anti-leakage frame v6 is arranged around the bottom of the lifting support plate v3. By increasing the height of the anti-leakage frame v6 at the bottom of the lifting support plate v3, it can prevent sewage from leaking from the gap between the lifting support plate v3 and the inner wall of the box j96 during the filtration of sewage, thereby improving the filtration effect of sewage through the filter press bag v9, so that the liquid in the sewage can fully pass through the filter press bag v9 and flow upward, while the sludge cannot pass through the filter press bag v9 and settles in the sinking tank j97, thereby accelerating the separation speed of the sludge and the liquid in the sewage and the comprehensiveness of the separation.

[0030] Wherein, the lifting component 1q includes a driving tube q2, a bearing q9, a worm q6, a lifting slider q4, a protective tube q5, and a supporting bottom plate q1. A bearing q9 is provided in the middle of the driving tube q2, and the bearing q9 is installed inside the upper end of the box j96. A worm q6 is welded to the lower end of the driving tube q2. The upper end of the driving tube q2 is sleeve-connected with the driving sleeve j56 and rotates synchronously. The worm q6 is passed through the lifting slider q4 with a clearance fit and is threaded. The lower end of the worm q6 is installed in the protective tube q5, and the worm q6 is passed through the lifting support plate v3 with a clearance fit. The lifting slider q4 is fixedly installed on the upper surface of the lifting support plate v3. The upper end of the protective tube q5 is fixed to the bottom surface of the lifting support plate v3. The bottoms of the protective tube q5 and the worm q6 are both arranged on the upper surface of the supporting bottom plate q1, and the supporting bottom plate q1 is fixedly welded to the inner wall of the box j96. A plug-in groove is provided at the middle end of the driving tube q2, and the plug-in groove coincides with the plug-in rod j51, so that when the driving tube sleeve j56 is sleeved and connected to the outside of the driving tube q2, the plug-in rod j51 is just inserted and installed in the plug-in groove of the driving tube q2, thereby improving the firmness of the driving tube sleeve j56 sleeved on the outside of the driving tube q2 and the stability of the driving operation, and at the same time improving the convenience of disassembly and assembly through the sleeve connection. The protective tube q5 has a pleated structure and is made of rubber material. It has good resilience and can be extended and retracted when the lifting slider q4 drives the lifting support plate v3 to lift and lower. The surface of the worm q6 is sealed and protected to prevent sludge from adhering to the surface of the worm q6 and causing the worm q6 to fail to normally drive the lifting slider q4 to lift and lower. The specific usage and function of this embodiment are as follows: In the present invention, when the drive sleeve j56 is sleeved and installed on the outside of the drive tube q2 at the top of the lifting component 1q, the plug-in rod j51 inside the drive sleeve j56 is just inserted and installed in the plug-in groove of the drive tube q2, thereby improving the firmness of the drive sleeve j56 sleeved on the outside of the drive tube q2 and the stability of the driven operation. At the same time, the convenience of disassembly and assembly is improved by the sleeve connection method. The drive sleeve j56 drives the drive tube q2 to rotate, thereby causing the worm q6 at the lower end of the drive tube q2 to rotate, driving the lifting slider q4 to rotate. The four lifting sliders q4 on the four lifting components 1q drive the lifting support plate v3 to steadily descend inside the box j96. During the descent, the liquid in the sewage is squeezed upwards through the filter bag v9, and in the process, the anti-leakage frame v6 is used to increase the height at the bottom of the lifting support plate v3 to prevent the sewage from leaking from the gap between the lifting support plate v3 and the inner wall of the box j96, thereby improving the effect of the sewage filtering through the filter bag v9, so that the liquid in the sewage can fully pass through the filter bag v9 to flow upwards, and the sludge has no The sludge that passes through the filter bag v9 is settled in the sinking tank j97, which speeds up the separation speed and comprehensiveness of the sludge and the liquid in the sewage. The protective pipe q5 can be extended and retracted when the lifting slider q4 drives the lifting support plate v3 to lift and lower, and the surface of the worm q6 is sealed and protected to prevent the sludge from adhering to the surface of the worm q6 and causing the worm q6 to be unable to normally drive the lifting slider q4 to lift and lower. After the sludge and liquid are fully separated by the filter bag v9, the lower end of the water pumping pipe 1c moves along with the lifting support plate v 3 descends, and in the process of descent, the telescopic hose 1s is pulled to extend, and the telescopic hose 1s plays a sealing and conducting effect. The sludge in the sewage is separated in the lower layer according to the lifting support plate v3. After the separation, the liquid in the sewage is in the upper surface of the lifting support plate v3. At this time, the lower end of the pumping pipe 1c is also in the upper surface of the lifting support plate v3. The liquid in the sewage after the sludge separation is fully extracted through the pumping pipe 1c, avoiding the fixed height of the pumping pipe 1c and only being able to extract the liquid above, resulting in incomplete extraction.
