Description

An integrated pump station with deodorization structure

Technical Field

The utility model belongs to the technical field of pump station equipment, and in particular relates to an integrated pump station with a deodorizing structure.

Background Art

Integrated pumping station is a lifting equipment for sewage, rainwater, drinking water and wastewater. The sewage and wastewater in the integrated pumping station will produce some organic waste gas with strong odor after fermentation, such as methane and hydrogen sulfide. The warehouses of traditional integrated pumping stations are interconnected, causing the waste gas to permeate the entire warehouse. When maintenance personnel go down to the warehouse for inspection, harmful odorous gases will affect the health of maintenance personnel. At the same time, the odorous gases will escape to the outside of the cabin through the ventilation ducts, causing air pollution.

In order to solve the above problems, several integrated pump stations with deodorization functions are disclosed in the prior art. For example, the patent authorization number is CN219261301U, which is an integrated prefabricated pump station with deodorization function. The pump station includes a platform arranged inside the pump station body, an activated carbon adsorption layer is fixed at the bottom of the platform, a deodorization box is fixedly connected to the bottom of the platform, a filter screen, a photocatalyst coating, a fluorescent lamp, etc. are fixedly connected inside the deodorization box, and an exhaust pipe and an exhaust pipe are connected above and below the deodorization box respectively. Although the deodorization component can achieve the purpose of deodorization, the following problems still exist: (1) During the deodorization process of the deodorization component, the activated carbon adsorption layer and the filter screen will adsorb particulate matter in the odor. After a certain period of use, the adsorption surface of the activated carbon adsorption layer and the filter screen will adsorb a large amount of particulate matter, which will affect its adsorption effect. Therefore, it is necessary to regularly replace or clean the activated carbon adsorption layer and the filter screen. However, the activated carbon adsorption layer and filter screen of this scheme are fixed inside the deodorization box, which is not convenient for replacement. In addition, the deodorization box is located at the bottom of the platform, and it is inconvenient for the staff to stand inside the pump station body to operate the deodorization components above. (2) The source of the odor comes from the sludge and other impurities discharged from the water inlet pipe into the pump station body. When they accumulate, anaerobic fermentation will occur and emit a foul odor. Eliminating the odor in the pump station body through the deodorization structure is ultimately a temporary solution, and the odor will continue to be emitted. Therefore, for further deodorization, it is necessary to clean the sludge and other impurities. However, in this scheme, it is inconvenient to clean the sludge in the pump station body, and it is necessary to manually scrub it after the sewage is discharged.

However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

Embodiment 1

As shown in Figures 1 and 2, this embodiment proposes an integrated pump station with a deodorization structure, including a pump casing 100. The pump casing 100 is provided with a water inlet pipe 101 and a drain pipe 102. In this embodiment, the drain pipe 102 is located above the water inlet pipe 101, and a water pump 103 is provided at the bottom of the pump casing 100. The water pump 103 is connected to the drain pipe 102.

A through hole 11 is provided on the pump plate, and a cover 10 for closing the through hole 11 is detachably connected to the partition 2. Specifically, the inner wall of the shell is connected with a partition 2, which is located above the water inlet pipe 101 and below the drain pipe 102. At least one hinge is commonly connected between the partition 2 and one end of the cover 10, and the other end of the cover 10 and the partition 2 can be detachably connected by means of snap connection, pin connection and threaded connection. It can be realized that the through hole 11 is closed when not in use to prevent a large amount of odor from leaking above the partition 2. When in use, the staff can open the cover 10 to enter. In order to facilitate the staff to enter the interior of the pump shell 100 for maintenance, a ladder 9 is connected to the inner wall of the pump shell 100. The ladder 9 is located on the upper and lower sides of the through hole 11. The top of the ladder 9 extends to the top of the pump station, and the bottom of the ladder 9 extends to the bottom of the through hole 11. A passage opening is provided on the top of the pump housing 100 and is located above the ladder 9 to facilitate the entry and exit of the staff.

Further, at least one group of deodorizing components 3 is connected above the partition 2, and the deodorizing components 3 include an exhaust hole 31 opened on the partition 2, a support plate 32 is connected to the exhaust hole 31, and an exhaust pipe 33 fixed above the partition 2 for covering the exhaust hole 31, and an exhaust fan 35 is detachably connected above the exhaust pipe 33. Specifically, the exhaust fan 35 can be fixed above the exhaust pipe 33 by means of snap connection, screw connection, etc., to ensure that the gas inside the exhaust pipe 33 can only be discharged through the exhaust fan 35. A cylindrical filter element 34 is placed above the support plate 32, and the top surface of the filter element 34 is in contact with the exhaust fan 35. The filter element 34 purifies the odor, and the exhaust fan 35 discharges the purified air in the filter element 34 to the top of the partition 2. It is worth noting that the support plate 32 and the top surface of the partition 2 are at the same horizontal plane, and there is a certain distance between the support plate 32 and the exhaust hole 31, so that the odor can flow through the bottom of the partition 2 and the exhaust pipe 33.

When the water inlet pipe 101 discharges the water from the outside into the pump housing 100, most of the water is sewage, rainwater, drinking water and wastewater. When the water enters the pump housing 100, it will contain certain garbage, sludge and other debris. When the garbage, sludge and other debris are at the bottom of the pump housing 100 for a certain period of time, a bad smell will be generated. The bad smell will affect the environment around the pump station to a certain extent, and will also have a certain impact on the physical and mental health of the staff. Therefore, a partition 2 is designed to isolate the odor at the bottom of the pump station to prevent the odor from leaking and affecting the surrounding environment. At the same time, in order to remove the odor isolated at the bottom of the pump housing 100, a deodorizing component 3 is provided in the pump housing 100, and the odor under the partition 2 is extracted by the exhaust fan 35. In the process of extracting the odor, the odor is purified by the filter cartridge and discharged by the exhaust fan 35. The odor under the partition 2 is purified and discharged by the deodorizing component 3, which effectively solves the problem of the odor in the pump housing 100 polluting the surrounding environment.

Furthermore, in order to facilitate the replacement of the filter element 34, at least three groups of springs 36 are connected above the support plate 32, and a top plate 37 for lifting the filter element 34 so that the top surface of the filter element 34 abuts against the exhaust fan 35 is connected above the spring 36. The bottom surface of the filter element 34 is fitted with the top plate 37 by the spring 36, and the top surface of the filter element 34 abuts against the exhaust fan 35, so that the odor can only enter the inside through the side wall of the filter element 34. The odor undergoes multiple purifications in the process of entering the inside through the filter element 34. Because the bottom of the filter element 34 is in a closed state, the purified odor can only be discharged after being extracted by the exhaust fan 35, and the odor is prevented from leaking to a certain extent. In the process of replacing the filter element 34, the exhaust fan 35 is disassembled in advance, and the filter element 34 can be directly taken out after disassembly, and then the new filter element 34 is placed in a suitable position above the top plate 37, and the filter element 34 and the top plate 37 below the filter element 34 are pressed down by the exhaust fan 35, and the exhaust fan 35 is installed after pressing down. After installation, the top plate 37 supports the filter element 34 under the force of the spring 36 to close the bottom of the filter element 34, and the top of the filter element 34 abuts against the bottom of the exhaust fan 35. This design makes the replacement of the filter element 34 more convenient and quick.

The filter element 34 can purify the odor to a certain extent and remove the odor. At the same time, the filter element 34 also has a certain barrier effect on the bacteria in the odor, but the bacteria cannot be completely eliminated by the filter element 34 alone, and a small number of bacteria will still escape the filter screen in the filter element 34 and enter the inside of the filter element 34. Therefore, at least one set of disinfection components 4 is detachably connected above the support plate 32. The disinfection component 4 is inside the filter element 34. The disinfection component 4 is an ultraviolet lamp in this embodiment, which irradiates the microorganisms inside the filter element 34 with ultraviolet rays to make them inactive, thereby achieving a sterilization effect.

The operating principle of this device is as follows:

The sewage flowing into the bottom of the pump casing 100 through the water inlet pipe 101 is easy to produce toxic gases such as hydrogen sulfide and carbon monoxide. The gases gather and stink, which will pollute the environment around the pump station to a certain extent and affect the physical and mental health of the staff.

Therefore, the utility model is provided with a partition 2 at the bottom of the pump housing 100, and the partition 2 isolates the sewage and odor at the bottom of the pump housing 100. A deodorizing assembly 3 is connected above the partition 2, and the deodorizing assembly 3 includes a support plate 32, a filter element 34, an exhaust pipe 33, and an exhaust fan 35. When the bottom of the pump housing 100 needs to be deodorized, the exhaust fan 35 is turned on, and the odor at the bottom of the pump housing 100 enters the exhaust pipe 33 through the exhaust hole 31. Since the exhaust fan 35 is turned on, the vent in the exhaust fan 35 is inside the filter element 34. During the process of the exhaust fan 35 sucking the odor inside the exhaust pipe 33 into the filter element 34, the filter element 34 filters the odor, and the filtered odor is inside the filter element 34, and is extracted by the exhaust fan 35 and discharged to the outside of the exhaust pipe 33.

When the filter element 34 needs to be replaced, the exhaust fan 35 above the exhaust pipe 33 is removed, and then the filter element 34 trapped on the top plate 37 is taken out, and then a new filter element 34 is replaced and placed in a suitable position above the top plate 37, and the filter element 34 is pressed down by the exhaust fan 35, and then the exhaust fan 35 is fixed above the exhaust pipe 33. The top plate 37 is always closed by the force of the spring 36, and the filter element 34 is pushed upward, so that the top surface of the filter element 34 abuts against the bottom of the exhaust fan 35. The odor can only enter the inside of the filter element 34 through the side wall of the filter element 34, and then be discharged through the exhaust fan 35.

This design can prevent the odor in the pumping station from leaking out and polluting the surrounding environment to a certain extent, and at the same time lock the odor in the lower half of the pump casing 100. The odor in the lower half is removed by the deodorizing component 3, reducing the impact of the odor on the pumping station body, while also not hindering the staff from entering the pumping station for inspection and maintenance.

Embodiment 2

When the drain pipe 102 discharges water into the pump housing 100, there is not only sewage but also impurities such as sludge in the sewage. When the sludge and other impurities accumulate at the bottom, anaerobic fermentation will occur and emit a foul smell. Therefore, if you want to further deodorize, it is also necessary to clean the sludge in time. However, the existing design structure of the pump station body makes it necessary to manually flush and clean the sludge at the bottom after all the sewage is discharged, which is inconvenient.

Based on this, this embodiment proposes an integrated pump station with a deodorization structure, as shown in Figures 3 and 4. The other structures are the same as those in the first embodiment, except that, in this embodiment, the bottom of the pump housing 100 has a pit 5, the pit 5 is in the shape of an eccentric funnel, and a sludge trough 6 for collecting sludge and other debris is provided at the bottom of the pit 5. It also includes a screw conveyor assembly 7 for conveying sludge inside the pump housing 100, the bottom end of the screw conveyor assembly 7 is inside the sludge trough 6, the top end of the screw conveyor assembly 7 is located above the partition 2, and a sludge box 8 is also provided above the partition 2, and the screw conveyor assembly 7 is connected to the sludge box 8. The pit 5 collects the sludge inside the sludge trough 6, and the sludge inside the sludge trough 6 is transported to the sludge box 8 through the screw conveyor assembly 7. When the sludge is collected inside the sludge box 8, it is convenient for the staff to clean up the sludge later.

Furthermore, in the present embodiment, the screw conveyor assembly 7 includes a limiting shell 71, the bottom of the limiting shell 71 is in the sludge tank 6, the top of the limiting shell 71 passes through the partition 2 and extends to above the partition 2, and a driving motor 72 is arranged above the limiting shell 71. The driving motor 72 is a three-phase asynchronous motor commonly seen on the market in the present embodiment, and the output shaft of the driving motor 72 is connected to a rotating shaft 73. The rotating shaft 73 is inside the limiting shell 71, and the rotating shaft 73 passes through the top of the limiting shell 71 and extends to the bottom of the limiting shell 71. A spiral blade 74 is fixedly connected to the outer wall of the rotating shaft 73, and the sludge in the sludge tank 6 is transported to the sludge box 8 by the rotation of the spiral blade 74.

Specifically, the specific connection method between the screw conveyor assembly 7 and the sludge box 8 is that a sewage outlet is opened on the limiting shell 71, the sewage outlet is located above the partition 2, the sewage outlet is connected to the sludge pipe 8, and the sludge pipe 8 is connected to the sludge box 8; in this embodiment, the screw conveyor assembly 7 is inclined to facilitate the discharge of sludge from the sewage outlet, the sludge pipe 8 is above the sludge box 8, and the sludge pipe 8 is in a horizontal or inclined state, which is convenient for the sludge to flow into the sludge box 8, and the sludge box 8 is sealed to prevent odor leakage.

The sludge and other garbage at the bottom of the pump housing 100 are part of the odor source. The sludge is transported to the sludge box 8 by the screw conveyor, which is convenient for centralized treatment and more efficient. It is convenient to regularly clean the sludge in the sludge box 8, which prevents the sludge from being pushed to the bottom of the pump housing 100 and odorizing to a certain extent.

It is worth noting that the main function of the screw conveyor assembly 7 is to clean smelly sludge, silt and other substances that are easy to stink. It also has a certain cleaning effect on the garbage discharged from the water inlet pipe 101 into the pump casing 100. However, the garbage is directly discharged into the pump casing 100, and the floating garbage may block the water pump 103 to a certain extent. To avoid this phenomenon, a basket grille can be set at the water outlet of the drain pipe 102.

Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
