Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to a vacuum wastewater collection device. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly becoming a part of ordinary people's daily lives.

[0003] In the process of sewage treatment, in order to ensure the smooth flow of sewage, a vacuum drainage system is used. It is a useful supplement to the gravity drainage system and a new type of drainage system that is different from the gravity drainage system. It uses vacuum equipment to create a certain degree of vacuum in the pipes and uses air as the transport medium to achieve sewage collection.

[0004] In vacuum drainage, a collection box is required to collect sewage. Although existing collection boxes are equipped with filter screens, there is no cleaning mechanism for the filter screens. As a result, solid impurities easily accumulate on the filter screens, causing the mesh to become clogged. This affects the smooth flow of sewage and reduces the efficiency of sewage treatment. Therefore, we propose a vacuum sewage collection device. Utility Model Content

[0005] The purpose of this utility model is to provide a vacuum sewage collection device to solve the problem mentioned in the background art that although the existing collection box is equipped with a filter screen, there is no cleaning mechanism for the filter screen. As a result, solid impurities easily accumulate on the filter screen, causing the mesh to become clogged. This affects the smooth flow of sewage and reduces the sewage treatment efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vacuum sewage collection device, comprising a collection box body, a collection box cover fitted onto the upper surface of the collection box body, several fixing plates II fixedly installed on the side of the collection box cover, fixing bolts threaded between the fixing plates II and the collection box body, an inlet pipe through the collection box cover, an outlet pipe through the side of the collection box body, a filter screen movably arranged inside the collection box body, handles fixedly installed on both the left and right sides of the filter screen, and openings on both the left and right sides of the inner wall of the collection box body for the handles to be inserted. The first collection tank has two receiving slots on its front and rear sides, and a fixing plate is installed in the receiving slot. A motor is fixedly installed on the side of one of the fixing plates. A reciprocating screw is rotatably installed between the two fixing plates. The output shaft of the motor is fixedly connected to the reciprocating screw. A threaded sleeve is installed on the outer surface of the reciprocating screw. An installation plate is fixedly installed on the lower surface of the threaded sleeve. A cleaning brush is detachably installed on the lower surface of the installation plate. The cleaning brush is attached to the upper surface of the filter screen. An exhaust hole is opened on the collection tank cover, and an activated carbon adsorption screen is detachably installed in the exhaust hole.

[0007] The above solution utilizes a filter screen in conjunction with a cleaning brush. The rotation of a reciprocating screw drives a threaded sleeve to move horizontally back and forth, which in turn drives the cleaning brush to move back and forth via a mounting plate. This cleans the surface of the filter screen, preventing the accumulation of impurities that could clog the mesh and obstruct water flow. The cleaning brush can be easily disassembled using insert plates and clips, facilitating maintenance. Furthermore, by using an activated carbon adsorption screen, odors from wastewater can be effectively adsorbed. The rotating plate and locking rod, along with a locking nut, allow for convenient installation and removal of the activated carbon adsorption system.

[0008] In the above scheme, it should be noted that the motor is electrically connected to an external power supply.

[0009] In a preferred embodiment, a guide sleeve is fixedly installed on the outer surface of the threaded sleeve, and a guide rod is fixedly installed between the two fixed plates. The guide sleeve is slidably installed on the outer surface of the guide rod.

[0010] By adopting the above scheme, the sliding of the guide sleeve on the surface of the guide rod can support and limit the movement of the threaded sleeve on the surface of the reciprocating screw, prevent the threaded sleeve from rotating, and ensure good smoothness of movement.

[0011] In a preferred embodiment, an insert bracket is fixedly installed on the outer surface of the fixing plate, and an insert slot for inserting the insert bracket is provided on the inner wall of the receiving groove two on the collection box.

[0012] By using the above solution, the insertion of the insert bracket into the insert groove can limit the position of the fixing plate, preventing the fixing plate from moving horizontally within the receiving groove 2 on the collection box, thus achieving a good limiting effect.

[0013] In a preferred embodiment, telescopic sleeves are fixedly installed on both sides of the guide sleeve. The telescopic sleeves cover the outside of the reciprocating screw, and the end of the telescopic sleeve away from the guide sleeve is fixedly connected to a fixed plate at the same side.

[0014] By adopting the above solution, the reciprocating screw can be protected by the telescopic sleeve, preventing impurities from accumulating and getting stuck on the surface of the reciprocating screw, thus achieving a good protective effect.

[0015] In a preferred embodiment, the lower surface of the mounting plate is provided with a slot, the upper surface of the cleaning brush is fixedly mounted with an insert plate, the insert plate is inserted into the inner wall of the slot, the side of the insert plate is provided with a groove, and the inner wall of the groove is fixedly mounted with a spring and a telescopic rod, the ends of the spring and the telescopic rod are fixedly mounted with a locking plate, and the side of the mounting plate is provided with a slot opposite to the slot, the locking plate and the slot are used in conjunction.

[0016] Using the above solution, the insert plate is inserted into the slot, and the spring force drives the card plate into the slot, realizing a convenient installation operation of the cleaning brush and facilitating subsequent disassembly. The telescopic rod can support the movement of the card plate, improve stability, and prevent the card plate from shaking.

[0017] In a preferred embodiment, a sealing strip is affixed to the lower surface of the collection box cover, and the sealing strip is attached to the upper surface of the collection box body.

[0018] By adopting the above solution, the sealing strip can ensure a good seal between the collection box and the collection box cover.

[0019] In a preferred embodiment, a support frame is fixedly installed on the inner wall of the vent hole on the collection box cover. The support frame is fitted to the lower surface of the activated carbon adsorption net. Several rotating plates are rotatably installed on the upper surface of the collection box cover. Locking holes are opened on the rotating plates. Several locking rods are fixedly installed on the upper surface of the activated carbon adsorption net. The locking rods are locked inside the locking holes. The outer surface of the locking rods has threads and locking nuts are installed on the threads.

[0020] The above scheme uses a support frame to support the activated carbon adsorption net, and a rotating plate is rotated until the locking rod is engaged in the locking port. The locking nut is then tightened onto the locking rod to achieve the position compression and locking of the rotating plate, thereby realizing the installation and locking of the activated carbon adsorption net. The locking structure is simple and easy to operate.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This vacuum sewage collection device uses a filter screen in conjunction with a cleaning brush. The rotation of the reciprocating screw drives the threaded sleeve to move horizontally back and forth, which in turn drives the cleaning brush to move back and forth through the mounting plate. This achieves surface cleaning of the filter screen, preventing the accumulation of impurities that could clog the mesh and affect the smooth flow of water. The cleaning brush can also be easily disassembled using insert plates and clips, making it convenient for disassembly and maintenance.

[0023] This vacuum wastewater collection device, when used in conjunction with an activated carbon adsorption net, can effectively adsorb and treat the odor of wastewater. Furthermore, the device utilizes a rotating plate and locking rod with a locking nut to facilitate convenient assembly and disassembly of the activated carbon adsorption unit.

Detailed Implementation

[0035] Please see Figures 1-10 This utility model provides a vacuum sewage collection device, including a collection box 1. A collection box cover 2 is attached to the upper surface of the collection box 1. Several fixing plates 23 are fixedly installed on the side of the collection box cover 2.

An outlet pipe 4 is installed through the side of the collection box 1. A filter screen 5 is movably arranged inside the collection box 1. Handles 13 are fixedly installed on both the left and right sides of the filter screen 5. Receiving grooves for the handles 13 to be inserted are opened on both the left and right sides of the inner wall of the collection box 1. The front and rear sides of the housing 1 are provided with receiving slots 2, and fixed plates 6 are installed in the receiving slots 2. A motor 7 is fixedly installed on the side of one of the fixed plates 6. A reciprocating screw 8 is rotatably installed between the two fixed plates 6. The output shaft of the motor 7 is fixedly connected to the reciprocating screw 8. A threaded sleeve 9 is installed on the outer surface of the reciprocating screw 8. An installation plate 10 is fixedly installed on the lower surface of the threaded sleeve 9. A cleaning brush 11 is detachably installed on the lower surface of the installation plate 10. The cleaning brush 11 is attached to the upper surface of the filter screen 5. An exhaust hole is provided on the collection box cover 2, and an activated carbon adsorption screen 12 is detachably installed in the exhaust hole.

[0036] By using a filter screen 5 in conjunction with a cleaning brush 11, the rotation of the reciprocating screw 8 drives the threaded sleeve 9 to move horizontally back and forth, which in turn drives the cleaning brush 11 to move back and forth through the mounting plate 10. This achieves surface cleaning of the filter screen 5, preventing the accumulation of impurities that could clog the mesh and hinder water flow. The cleaning brush 11 can be easily disassembled using the insert plate 21 and the locking plate 20, facilitating disassembly and maintenance. In conjunction with an activated carbon adsorption screen 12, odors in wastewater can be effectively adsorbed. The rotating plate 26 and locking rod 27, along with the locking nut 28, enable convenient disassembly and assembly of the activated carbon adsorption screen.

[0037] A guide sleeve 14 is fixedly installed on the outer surface of the threaded sleeve 9, and a guide rod 15 is fixedly installed between the two fixed plates 6. The guide sleeve 14 is slidably installed on the outer surface of the guide rod 15. By setting the guide sleeve 14 to slide on the surface of the guide rod 15, the movement of the threaded sleeve 9 on the surface of the reciprocating screw 8 can be supported and limited, so as to avoid the threaded sleeve 9 from rotating and ensure good smoothness of movement.

[0038] A strip holder 17 is fixedly installed on the outer surface of the fixed plate 6. The inner wall of the receiving groove 2 on the collection box 1 is provided with a strip groove for the strip holder 17 to be inserted. By inserting the strip holder 17 into the strip groove, the fixed plate 6 can be limited, preventing the fixed plate 6 from moving horizontally in the receiving groove 2 on the collection box 1, thus achieving a good limiting effect.

[0039] Telescopic sleeves 16 are fixedly installed on both sides of the guide sleeve 14. The telescopic sleeves 16 cover the outside of the reciprocating screw 8. The end of the telescopic sleeve 16 away from the guide sleeve 14 is fixedly connected to the fixing plate 6 on the same side. The telescopic sleeves 16 can protect the reciprocating screw 8 and prevent impurities from accumulating and getting stuck on the surface of the reciprocating screw 8, thus achieving a good protective effect.

[0040] The lower surface of the mounting plate 10 has a slot, and the upper surface of the cleaning brush 11 is fixedly mounted with an insert plate 21. The insert plate 21 is inserted into the inner wall of the slot. The side of the insert plate 21 has a groove, and the inner wall of the groove is fixedly mounted with a spring 18 and a telescopic rod 19. The ends of the spring 18 and the telescopic rod 19 are fixedly mounted with a locking plate 20. The side of the mounting plate 10 is provided with a locking slot opposite the slot. The locking plate 20 and the locking slot work together. The insert plate 21 is inserted into the slot, and the spring force of the spring 18 drives the locking plate 20 to lock into the locking slot, realizing the convenient installation operation of the cleaning brush 11 and facilitating subsequent disassembly. The telescopic rod 19 can support the movement of the locking plate 20, improve stability, and prevent the locking plate 20 from shaking.

[0041] A sealing strip 22 is affixed to the lower surface of the collection box cover 2. The sealing strip 22 is attached to the upper surface of the collection box body 1. The sealing strip 22 can ensure a good sealing effect between the collection box body 1 and the collection box cover 2.

[0042] A support frame 25 is fixedly installed on the inner wall of the vent hole on the collection box cover 2. The support frame 25 is fitted to the lower surface of the activated carbon adsorption net 12. Several rotating plates 26 are rotatably installed on the upper surface of the collection box cover 2. The rotating plates 26 have locking holes. Several locking rods 27 are fixedly installed on the upper surface of the activated carbon adsorption net 12. The locking rods 27 are locked inside the locking holes. The outer surface of the locking rods 27 has threads and locking nuts 28 are installed on the threads. The support frame 25 is used to support the activated carbon adsorption net 12. The rotating plates 26 are rotated until the locking rods 27 are locked into the locking holes. The locking nuts 28 are screwed on to lock the locking rods 27 to achieve the position compression and locking of the rotating plates 26, thereby realizing the installation and locking of the activated carbon adsorption net 12. The locking structure is simple and easy to operate.

[0043] During operation, wastewater from the vacuum drainage system enters the collection tank 1 through the inlet pipe 3. After impurities are filtered out by the filter screen 5, it is discharged from the outlet pipe 4. Simultaneously, the motor 7 starts, driving the reciprocating screw 8 to rotate, which in turn drives the threaded sleeve 9 to move horizontally back and forth. This, in turn, drives the mounting plate 10 to continuously reciprocate the cleaning brush 11, cleaning the filter screen 5 and preventing clogging. At the same time, odors in the wastewater are adsorbed and removed by the activated carbon adsorption screen 12. When cleaning the filter screen 5, simply unscrew it. Unlock the collection box 1 and collection box cover 2 by fixing bolt 24, pull upward to remove collection box cover 2, then pull upward to remove fixing plate 6, and then take out cleaning brush 11. Then press the card plate 20 to make card plate 20 disengage from the card slot. At this time, the mounting plate 10 and cleaning brush 11 can be separated. Then pull up the handle 13 to pull out the filter screen 5. Unscrew the locking nut 28 to unlock the rotating plate 26, rotate the rotating plate 26 to make the locking rod 27 disengage from the locking port, and then the activated carbon adsorption screen 12 can be taken out upward.
