The spray ring pipe is arranged in a ring around the outside of the filter screen cylinder, ensuring that the water flow covers the entire circumference of the filter screen without any cleaning dead corners. High-pressure nozzles can spray high-pressure water to quickly remove stubborn impurities from the surface and pores of the filter screen. Through the setting of the detection components, the controller can receive signals from the differential pressure sensor and automatically control the opening and closing of the drain valve and the start of the backwash water flow. Differential pressure sensor one and differential pressure sensor two can monitor the pressure difference between the front and rear ends of the filter screen in real time.

Description

Technical Field

[0001] This utility model relates to the field of decontaminator technology, and in particular to a decontaminator with a built-in backwashing function. Background Technology

[0002] As the core equipment for media purification in pipeline systems, dirt separators are widely used in industrial circulating water systems, HVAC systems, water supply and drainage projects, chemical pipelines and other fields. Their core function is to intercept solid impurities such as rust, silt, fiber, and welding slag in the media, preventing impurities from clogging key equipment such as valves, pumps, and heat exchangers, thus ensuring stable system operation and extending equipment lifespan.

[0003] After prolonged use, the internal filters of existing traditional decontamination devices become clogged. Once clogged, the machine must be stopped, the housing disassembled, and the filters removed for manual cleaning, which is troublesome, time-consuming, and labor-intensive. For systems with high requirements for continuous operation, shutdown will lead to production interruption or heating suspension, resulting in significant economic losses.

[0004] Therefore, we propose a desiccant with built-in backwashing function. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a decontaminant with a built-in backwashing function.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A decontaminator with a built-in backwashing function includes a decontaminator body, a filter screen cylinder fixedly installed inside the decontaminator body, a backwash pipe fixedly installed at the upper end of the decontaminator body, and a spray ring pipe fixedly installed at the inner end of the decontaminator body. The spray ring pipe is connected to the backwash pipe, and a plurality of high-pressure nozzles are evenly arranged on the spray ring pipe. The spray nozzles face the filter screen cylinder. A detection component is fixedly installed at the outer end of the filter screen cylinder. The backwash pipe facilitates connection to an external high-pressure water source and delivers backwash water to the spray ring pipe. The spray ring pipe is arranged in a ring around the outside of the filter screen cylinder to ensure that the water flow covers the entire circumference of the filter screen without any cleaning dead corners. The high-pressure nozzles can spray high-pressure water to quickly remove stubborn impurities from the surface and pores of the filter screen.

[0008] As a further embodiment of this utility model: the detection component includes a controller. The controller is fixedly installed at the outer end of the main body of the filter. A differential pressure sensor is fixedly installed at one end of the filter cylinder, and a differential pressure sensor is fixedly installed at the other end of the filter cylinder. The differential pressure sensor is electrically connected to the controller. Both differential pressure sensors are commercially available mature electronic components. The controller can receive signals from the differential pressure sensors and automatically control the opening and closing of the drain valve and the start of the backwash water flow. The differential pressure difference between the front and rear ends of the filter can be monitored in real time through the differential pressure sensor. When the accumulation of impurities causes the differential pressure to reach a set threshold, a signal is sent to the controller to trigger the backwash process.

[0009] As a further improvement of this utility model: a drain pipe is fixedly installed at the lower end of the main body of the dirt separator, and a drain valve is installed in the middle of the drain pipe. The impurities and sewage stripped by backwashing can be discharged from the equipment through the drain pipe, and the drain valve can be opened and closed under the control of the controller.

[0010] As a further embodiment of this utility model: a water inlet pipe is fixedly installed at the left end of the main body of the filter, and a water outlet pipe is fixedly installed at the right end of the main body of the filter. The water inlet pipe can introduce the medium to be filtered into the main body of the filter, and the water outlet pipe can transport the filtered purified medium to the downstream pipeline.

[0011] As a further improvement of this utility model: both the inlet pipe and the outlet pipe are fixedly equipped with flanges, and annular sealing gaskets are fixedly embedded at the ends of the flanges away from the main body of the filter. The flanges facilitate the quick connection of the inlet pipe and the outlet pipe to the pipeline system, and the annular sealing gaskets enhance the sealing of the connection and prevent the medium from leaking in the flange connection gap.

[0012] As a further improvement of this utility model: an inspection port is fixedly provided at the outer end of the main body of the dirt separator, and an inspection cover plate is sealed to the outer end of the inspection port. The inspection port provides a channel for the inspection and replacement of internal components. The inspection cover plate closes the inspection port to ensure the airtightness of the equipment. When maintenance is required, the screws can be removed for maintenance.

[0013] Compared with the prior art, this utility model provides a desiccant with a built-in backwashing function, which has the following beneficial effects:

[0014] 1. This utility model facilitates connection to an external high-pressure water source through the backwash pipe, and delivers backwash water to the spray ring pipe. The spray ring pipe is arranged in a ring around the outside of the filter screen cylinder, ensuring that the water flow covers the entire circumference of the filter screen without any cleaning dead corners. High-pressure water can be sprayed out through the high-pressure nozzle, which can quickly remove stubborn impurities from the surface and pores of the filter screen. Through the setting of the detection component, the controller can receive the differential pressure sensor signal and automatically control the opening and closing of the drain valve and the start of the backwash water flow. Differential pressure sensor one and differential pressure sensor two can monitor the pressure difference between the front and rear ends of the filter screen in real time. When the accumulation of impurities causes the pressure difference to reach the set threshold, a signal is sent to the controller to automatically trigger the backwash process, which improves the practicality of the decontaminant with built-in backwash function.

[0015] 2. This utility model facilitates quick connection of the inlet and outlet pipes to the piping system through the flange design. The annular sealing gasket enhances the sealing performance at the connection, preventing media leakage in the flange connection gap. The inspection port provides access for internal component maintenance and replacement. The inspection cover seals the inspection port, ensuring the equipment's airtightness. When maintenance is required, the screws can be removed for inspection, improving the convenience of the desiccant with built-in backwashing function.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Example: Please refer to Figures 1-4 This utility model provides a technical solution:

[0025] A decontaminator with a built-in backwashing function includes a decontaminator body 1, a filter screen cylinder 2 fixedly installed inside the decontaminator body 1, a backwash pipe 3 fixedly installed at the upper end of the decontaminator body 1, and a spray ring pipe 4 fixedly installed at the inner end of the decontaminator body 1. The spray ring pipe 4 is connected to the backwash pipe 3, and a plurality of high-pressure nozzles 5 are evenly arranged on the spray ring pipe 4. The spray nozzles 5 face the filter screen cylinder 2. A detection component 6 is fixedly installed at the outer end of the filter screen cylinder 2. The backwash pipe 3 facilitates connection to an external high-pressure water source and delivers backwash water to the spray ring pipe 4. The spray ring pipe 4 is arranged in a ring around the outside of the filter screen cylinder 2 to ensure that the water flow covers the entire circumference of the filter screen without any cleaning dead corners. The high-pressure water can be sprayed out through the high-pressure nozzles 5, which can quickly remove stubborn impurities from the surface and pores of the filter screen.

[0026] In this embodiment, the preferred detection component 6 includes a controller 61. The controller 61 is fixedly installed at the outer end of the filter body 1. A differential pressure sensor 62 is fixedly installed at one end of the filter cylinder 2, and a differential pressure sensor 63 is fixedly installed at the other end of the filter cylinder 2. The differential pressure sensor 62 and the differential pressure sensor 63 are electrically connected to the controller 61. Both the differential pressure sensor 62 and the differential pressure sensor 63 are commercially available mature electronic components. The controller 61 can receive the differential pressure sensor signals and automatically control the opening and closing of the drain valve 8 and the start of the backwash water flow. The differential pressure difference between the front and rear ends of the filter can be monitored in real time through the differential pressure sensor 62 and the differential pressure sensor 63. When the accumulation of impurities causes the differential pressure to reach a set threshold, a signal is sent to the controller 61 to trigger the backwash process.

[0027] In this embodiment, a drain pipe 7 is fixedly installed at the lower end of the preferred dirt separator body 1, and a drain valve 8 is installed in the middle of the drain pipe 7. The impurities and sewage stripped by backwashing can be discharged from the equipment through the drain pipe 7, and the drain valve 8 can be opened and closed under the control of the controller 61.

[0028] In this embodiment, a water inlet pipe 9 is fixedly installed at the left end of the preferred dirt separator body 1, and a water outlet pipe 10 is fixedly installed at the right end of the dirt separator body 1. The water inlet pipe 9 can introduce the filter medium into the dirt separator body 1, and the water outlet pipe 10 can transport the filtered purified medium to the downstream pipeline.

[0029] In this embodiment, flanges 11 are fixedly installed at the ends of the preferred inlet pipe 9 and outlet pipe 10. An annular sealing gasket 12 is fixedly embedded at the end of the flange 11 away from the main body 1 of the dirt separator. The flange 11 facilitates the quick connection of the inlet pipe 9 and outlet pipe 10 to the pipeline system. The annular sealing gasket 12 enhances the sealing of the connection and prevents the medium from leaking in the flange connection gap.

[0030] In this embodiment, a maintenance port 13 is fixedly provided on the outer end of the preferred dirt separator body 1. A maintenance cover plate 14 is sealed to the outer end of the maintenance port 13. The maintenance port 13 provides a channel for the maintenance and replacement of internal components. The maintenance cover plate 14 closes the maintenance port 13 to ensure the equipment is airtight. When maintenance is required, the screws can be removed for maintenance.

[0031] Working Principle: In this embodiment, a filter with a built-in backwashing function is first connected to the pipeline system via flanges 11 at the ends of the inlet pipe 9 and outlet pipe 10. An annular sealing gasket 12 ensures a leak-free connection. The backwash pipe 3 connects to an external high-pressure water source or the system return pipeline, and the drain pipe 7 connects to a sewage collection or discharge pipeline. The pipeline medium enters the filter body 1 through the inlet pipe 9 and flows to the filter cylinder 2. The filter cylinder 2 is made of stainless steel with a specific pore size, trapping solid impurities such as rust, silt, and fibers larger than the pore size. These impurities adhere to the outside of the filter screen. The purified medium, after being filtered by the filter cylinder 2, passes through the pores of the filter screen and enters the inside of the filter cylinder 2. It is then transported to the downstream pipeline system through the outlet pipe 10, ensuring that subsequent equipment is not blocked by impurities. Differential pressure sensor 62 and differential pressure sensor 63 detect the pressure difference between the front and rear ends of the filter cylinder 2 in real time, and the data is synchronously transmitted to the controller 61, dynamically reflecting the degree of filter contamination. As impurities accumulate in the filter cylinder, the filter is cleaned and cleaned. As impurities accumulate on the outside of the filter screen, the flow resistance increases, and the pressure difference between the front and rear ends gradually rises. When the pressure difference reaches the preset threshold of the controller 61, the controller 61 automatically triggers the backwash process without manual intervention. The controller 61 instructs the external high-pressure water source to open, and the backwash water flows through the backwash pipe 3 into the spray ring pipe 4. The spray ring pipe 4 is arranged in a ring inside the filter screen cylinder 2, and the high-pressure nozzles 5 evenly distributed on it convert the water flow into a high-pressure jet, which precisely washes the outside of the filter screen. The impact force of the high-pressure jet quickly removes stubborn impurities from the surface and pores of the filter screen. The removed impurities settle to the bottom of the main body 1 of the filter under the action of gravity. At the same time as the backwash starts, the controller 61 controls the drain valve 8 to open automatically, and the wastewater containing impurities is quickly discharged from the equipment through the drain pipe 7 to ensure that the impurities are completely removed. When the equipment malfunctions, the pipeline valve can be closed, the inspection cover 14 can be removed, and the internal components such as the filter screen cylinder 2, the spray ring pipe 4, and the high-pressure nozzles 5 can be directly inspected through the inspection port 13 for cleaning, replacement, or repair.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
