Abstract
Description
Technical Field
[0001] This application relates to a purification device, and more particularly to a wastewater purification pretreatment device. Background Technology
[0002] Rainwater, as natural precipitation, is abundant and widely distributed. Recycling and reusing it can effectively increase the water supply and improve water resource utilization. Recycled rainwater can be used in various fields such as agriculture, industry, construction, and car washing. However, rainwater becomes wastewater mixed with impurities after it falls to the ground, potentially containing pollutants such as mud, stones, leaves, and animal feces. If stored directly without purification, these pollutants will affect the storage time and subsequent use of the rainwater. Therefore, wastewater purification equipment is needed to treat the wastewater.
[0003] In existing technologies, wastewater is generally treated by filtration. However, when the filter element becomes clogged with debris, it loses its filtering function and needs to be replaced in time, which is troublesome and costly. Utility Model Content
[0004] The purpose of this invention is to provide a wastewater purification pretreatment device that can purify rainwater without replacing the filter cartridge.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is a wastewater purification pretreatment device, including a debris-blocking chamber. A rotating rod is installed inside the debris-blocking chamber. The rotating rod is horizontally positioned and connected to a debris-blocking component. The debris-blocking component intercepts debris in the wastewater. Rotating the rotating rod can drive the debris-blocking component to rotate, causing the intercepted debris to move within the debris-blocking chamber. A push plate is provided inside the debris-blocking chamber, and a storage compartment is provided on one side of the debris-blocking chamber. After the debris moves to the position corresponding to the push plate, the push plate can push the debris on the debris-blocking component into the storage compartment. A filtration device is provided below the debris-blocking chamber to perform secondary filtration of the wastewater.
[0006] Furthermore, the debris-blocking assembly includes debris-blocking plates arranged in an array around the central axis of the rotating rod, and the debris-blocking plates are moved by the rotation of the rotating rod.
[0007] Furthermore, the bottom of the wastewater trap has several filter holes that intercept impurities in the wastewater.
[0008] Furthermore, the storage compartment is equipped with a miscellaneous basket, which is movably connected to the storage compartment. The miscellaneous basket can be pulled out from inside the storage compartment, and a filter screen is provided at the bottom of the miscellaneous basket.
[0009] Furthermore, the bottom plate of the storage compartment is equipped with a filter screen, through which sewage inside the storage compartment flows.
[0010] Furthermore, the filtration device includes a filtration unit and a bottom housing. The filtration unit consists of several filter cottons, which are in contact with the inner wall of the bottom housing.
[0011] Furthermore, the debris-blocking chamber is provided with a limiting through hole, and the side wall of the debris-blocking plate is provided with a positioning hole. A limiting rod passes through the limiting through hole, and one end of the limiting rod is inserted into the positioning hole. The limiting rod positions the debris-blocking component.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: Sewage flows into the debris-blocking chamber through the inlet, and the debris-blocking component intercepts the impurities in the sewage. A push plate is provided in the debris-blocking chamber. When too much debris on the debris-blocking component affects sewage filtration, the debris-blocking component is rotated to move the debris on the debris-blocking plate to align with the push plate, and the push plate pushes the debris into the storage chamber. The normal filtration of sewage is not affected when cleaning the debris, realizing continuous filtration of sewage and avoiding the need for periodic replacement of filter cartridges, thereby saving costs. A connecting pipe is provided at the bottom of the storage chamber. Water carried by the debris in the storage chamber will flow into the filtration device through the connecting pipe to realize water recycling and reuse. At the same time, sewage in the debris-blocking chamber flows into the filtration device through the connecting pipe. The filtration device is equipped with a filtration unit, which performs secondary filtration of sewage. Attached Figure Description

Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. It should be understood that the preferred embodiments described herein are only for illustration and explanation of the present utility model and are not intended to limit the present utility model.

The components of the embodiments of the present utility model described and shown in the accompanying drawings can be arranged and designed in various different configurations. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. In the embodiments, the components of the embodiments of the present application described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of the present application.
[0020] See Figures 1 to 5 As shown, a wastewater purification pretreatment device includes a base 1 placed on the ground. A filter device 2 is mounted on the base 1. The filter device 2 is box-shaped, meaning it has a storage space inside. A drain outlet is located at the bottom of the filter device 2, and a drain pipe 3 is connected to the drain outlet. A connection port is located above the filter device 2, and a connecting pipe 4 is connected to the connection port. The connecting pipe 4 is vertically arranged, and a debris-blocking bin 5 is connected to the top of the connecting pipe 4. The debris-blocking bin 5 is cylindrical, and baffles are provided at both ends of the debris-blocking bin 5, meaning it has a storage space inside. A water inlet hopper 6 is located at the top of the debris-blocking bin 5, through which wastewater enters the debris-blocking bin 5. A debris-blocking component 7 is located inside the debris-blocking bin 5, which filters the wastewater. A storage bin 8 is connected to one side of the debris-blocking bin 5. After the debris intercepted by the debris-blocking component 7 is controlled, it can be discharged from the debris-blocking bin 5 into the storage bin 8. After the debris is intercepted in the debris trap 5, the debris is separated from the water. The water is discharged downwards through the connecting pipe 4 into the filter device 2. After secondary filtration by the filter device 2, it is finally discharged through the drain pipe 3.
[0021] The debris-blocking bin 5 is arranged horizontally. A through hole is provided on one side baffle of the debris-blocking bin 5, and a rolling bearing is installed in the through hole. A notch is provided on the inner wall of the other side baffle, and a rolling bearing is installed in the notch. A rotating rod 9 passes through the rolling bearing in the through hole. One end of the rotating rod 9 extends to connect with the rolling bearing in the notch. The free end of the rotating rod 9 extends outward from the debris-blocking bin 5, and a drive motor 10 is connected to the free end of the rotating rod 9. When the drive motor 10 is powered on, the drive motor 10 works to drive the rotating rod 9 to rotate. At the same time, in order to save energy, a rotating handle can be installed on the free end of the rotating rod 9. The operator holds the rotating handle to rotate the rotating rod 9.
[0022] In order to intercept and treat the sewage flowing into the interception chamber 5 from the inlet hopper 6, the interception assembly 7 is connected to the rotating rod 9. When the rotating rod 9 rotates, it can drive the interception assembly 7 to rotate inside the interception chamber 5. The interception assembly 7 includes an interception plate 11. The interception surface of the interception plate 11 is an arc-shaped curved surface. At this time, the interception plate 11 has two straight edges, which are parallel to each other. One straight edge is fixedly connected to the rotating rod 9, and the other straight edge is in contact with the inner wall of the interception chamber 5. At this time, the interception plate 11 extends along the length direction of the rotating rod 9, and extends to both ends of the interception plate 11 to contact the inner wall of the baffle. The interception plate 11 is provided with filter holes. There are several filter holes. When the sewage passes through the interception plate 11, the impurities in the sewage are intercepted by the interception plate 11, and the water flows downward through the filter holes.
[0023] There are three debris-blocking plates 11, which are arranged in an array around the central axis of the rotating rod 9. At this time, the three debris-blocking plates 11 form a debris-blocking assembly 7. That is, rotating the rotating rod 9 can drive the debris-blocking assembly 7 to rotate in the debris-blocking chamber 5. The area between two adjacent debris-blocking plates 11 located in the debris-blocking chamber 5 is the filtration space.
[0024] In the initial state, one of the baffle plates 11 of the baffle assembly 7 is located directly below the inlet hopper 6, with the baffle surface of the baffle plate 11 facing upwards. Wastewater flows from the inlet hopper 6 into the baffle chamber 5 and is filtered by the baffle plate 11 below. When too much debris accumulates on the baffle plate 11 and affects wastewater filtration, the baffle assembly 7 is rotated. The debris is pushed away by the baffle plate 11. As the baffle assembly 7 rotates, the wastewater continues to flow downwards through the baffle chamber 5 and reaches the bottom of the baffle chamber 5. At this point, there are several filter holes at the bottom of the baffle chamber 5. The wastewater enters the connecting pipe 4 after passing through these filter holes. If there is any intercepted debris on the upper surface of the bottom of the baffle chamber 5, the baffle assembly 7 continues to rotate, and the baffle plate 11 moves upwards to scrape away the debris at the bottom of the baffle chamber 5.
[0025] A connecting funnel is provided at the bottom of the debris-blocking bin 5. The upper opening of the connecting funnel is larger than the lower opening. The connecting funnel is set vertically, and the upper opening of the connecting funnel is connected to the bottom of the debris-blocking bin 5. The upper opening of the connecting funnel surrounds the filter hole area at the bottom of the debris-blocking bin 5. The lower opening of the connecting funnel is connected to the top of the connecting pipe 4. That is, the debris in the debris-blocking bin 5 flows downward through the connecting funnel, through the connecting pipe 4, and into the filter device 2.
[0026] In order to clean up the debris intercepted by the baffle plate 11, a push plate 15 is provided in the baffle chamber 5. The push plate 15 can move along the length of the rotating rod 9. When the push plate 15 moves in the filter space, it can push and clean up the debris intercepted by the baffle plate 11. At this time, the push plate 15 divides the filter space into two independent spaces. When it is necessary to discharge the debris in the filter space, the push plate 15 moves towards the storage chamber 8. During this process, the push plate 15 moves in the corresponding filter space and pushes the debris in the filter space to be close to the storage chamber. A cleaning port 13 is provided on the baffle plate that contacts the storage chamber 8. The push plate 15 can pass through the cleaning port 13, so that the debris can be pushed into the storage chamber 8. That is, the space in the storage chamber 8 is connected to the space in the baffle chamber 5. The storage chamber 8 is a rectangular box, that is, the storage chamber 8 has storage space, and the debris can be stored in the storage chamber 8.
[0027] To move debris into storage compartment 8, a push rod 14 is connected to the push plate. The push rod 14 passes through the baffle away from storage compartment 8. The inner end of the push rod 14 is fixed to the push plate, and the outer end of the push rod 14 is fixed with a handle. The push rod 14 can be moved axially, thereby moving the push plate horizontally. The push rod can be moved manually or electrically. When using electric control, an electric push rod and a trigger switch are required. When the debris-blocking assembly 7 rotates and the debris-blocking plate rotates 120°, the trigger switch is activated. The trigger switch applies a control signal to the electric push rod, causing the electric push rod to move. The rod is in operation. The trigger switch can be an existing product such as an infrared sensor. The principle of controlling the electric push rod by triggering the switch is existing technology. It is only one implementation method for controlling the push rod 14 in this application, and will not be described in detail here. In order not to affect the normal rotation of the debris blocking component 7, a push plate groove is provided on the inner wall of the baffle away from the storage compartment. The push plate 15 is adapted to the push plate groove. That is, in the initial state, the push plate 15 is attached to the push plate groove. When it is necessary to clean the debris, push the handle 16 to drive the push plate 15 to push the debris into the storage compartment 8. After cleaning is completed, pull the handle in the opposite direction to reset the push plate 15.
[0028] Meanwhile, to facilitate the cleaning of debris in the storage compartment 8, a discharge port is provided on the vertical side wall of the storage compartment 8, and a debris basket 17 is provided inside the storage compartment 8. The debris basket 17 can be pulled out from the discharge port. The debris basket 17 has a rectangular basket structure, that is, the top of the debris basket 17 has an opening and the bottom has a sealing plate. At the same time, the vertical outer wall of the debris basket 17 is in contact with the inner wall of the storage compartment 8, and the bottom sealing plate of the debris basket 17 is in contact with the upper surface of the bottom plate of the storage compartment 8. That is, the push plate 15 pushes the debris into the storage compartment 8, and the debris falls down into the debris basket 17. When the debris in the debris basket 17 needs to be cleaned, the debris basket 17 is pulled out from the discharge port, and then the debris in the debris basket 17 is discharged.
[0029] When the debris is pushed into the storage compartment 8, it may contain some moisture. In order to recycle the water, a filter screen is provided on the bottom sealing plate of the debris basket 17 and a filter screen is also provided on the bottom plate of the storage compartment 8. When the debris is pushed into the storage compartment 8, the water mixed in with the debris will flow downward through the filter screens on the bottom sealing plate of the debris basket 17 and the bottom plate of the storage compartment 8.
[0030] A connecting pipe 18 is provided below the storage compartment 8. The upper end of the connecting pipe 18 is funnel-shaped, that is, the opening at the upper end of the connecting pipe 18 is larger than the opening at the lower end of the connecting pipe 18. The upper end of the connecting pipe 18 is connected to the bottom plate of the storage compartment 8. At the same time, a connecting port is provided on the side wall of the filter device 2. The bottom end of the connecting pipe 18 extends downward and connects with the connecting port, that is, the water in the storage compartment 8 flows into the filter device 2 through the connecting pipe 18.
[0031] In order to perform secondary filtration of the sewage entering the filter device 2, the filter device 2 includes a bottom shell 12 and a filter unit. The filter unit is located inside the bottom shell 12. The filter unit 19 is composed of several filter cottons 20. The filter cottons 20 are in close contact with the inner wall of the bottom shell 12. The filter cottons 20 block relatively small debris such as soil particles, sand, and bird droppings that the debris blocking component 7 cannot intercept. The sewage flows through the several filter cottons 20, and the several filter cottons 20 filter the sewage layer by layer. Finally, the filtered water is discharged outward through the drain pipe at the bottom of the filter device 2.
[0032] In addition, when filtering sewage, the debris-blocking assembly 7 has a limiting through hole on the baffle at the end of the debris-blocking chamber 5 to ensure its stability. At the same time, a positioning hole is provided on the side wall of the debris-blocking plate 11 that contacts the baffle (all three debris-blocking plates 11 have positioning holes). A limiting rod passes through the limiting through hole, and one end of the limiting rod extends into the limiting hole in the debris-blocking chamber 5. At this time, the limiting rod positions the debris-blocking assembly 7. When the debris-blocking assembly 7 needs to be rotated, the limiting rod can be pulled outward.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
