Description

Technical Field

[0001] This utility model relates to the technical field of pipeline filtration equipment, and in particular to a main drainage pump jet pipeline filtration device. Background Technology

[0002] Underground drainage systems in coal mines are a powerful guarantee for safe production. With the development of science and technology and the increasing safety requirements of coal mines, automatic underground drainage systems will inevitably become the trend in the development of underground drainage systems. In the design process of transitioning from traditional drainage systems to automatic drainage systems, how to control each link of the drainage system is the key to the operation of the automatic underground drainage system.

[0003] In the field of general-purpose pumps, most dry-mounted centrifugal pumps, except for self-priming pumps with built-in self-priming capabilities and ordinary centrifugal pumps that rely on positive pressure water intake, require a foot valve and need to be primed with water before the first start-up. Therefore, in order for dry-mounted centrifugal pumps to quickly enter working condition, a jetting device needs to be designed to work in conjunction with an air compressor to create a vacuum and assist the centrifugal pump in achieving rapid, repeated, and sustained self-priming capabilities.

[0004] Before starting a centrifugal water pump, a vacuum system using a jet pump must be used to evacuate the pump chamber. The pump can only start normally when a certain vacuum is reached in the pump chamber and the suction pipe and pump casing are filled with water. Otherwise, the pump will not be able to draw water when it rotates, resulting in "dry burning" and seriously affecting the service life of the pump.

[0005] Defects and shortcomings of existing technology:

[0006] 1. The existing technology uses static pressure water to create a vacuum. The equipment uses static pressure water to create a vacuum in the pump chamber by jetting water through the nozzle of the jet pump. The vacuuming operation is controlled by a solenoid valve installed at the inlet of the jet pump. The solenoid valve controls the flow of static pressure dust removal water. In actual use, it may happen that after the solenoid valve is opened, the water contains a lot of impurities that block the jet nozzle orifice, making it impossible to achieve the vacuum required to fill the water, and the water pump cannot start.

[0007] 2. There are also cases where the equipment is not very stable, which can also affect its normal use.

[0008] Therefore, this utility model provides a main drainage pump jet pipeline filtration device. Utility Model Content

[0009] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a main drainage pump jet pipeline filtration device.

[0010] To achieve the above objectives, this utility model adopts the following technical solution: a main drainage pump jet pipeline filtration device, including a dust removal main pipe,

[0011] The dust collection manifold is fitted with a filter cover on its outer side;

[0012] A Y-type filter is installed on the top of the filter cover, a filter cylinder is installed inside the Y-type filter, a flow guide cylinder is installed inside the filter cover, and a filter screen is installed inside the flow guide cylinder.

[0013] One end of the dust suppression main pipe is equipped with a jet pipe, and a sealing sleeve is fitted on the outside of the jet pipe. A fixing frame is installed on the outside of the sealing sleeve. Limiting plates are installed on the top of the fixing frame and on both sides of the sealing sleeve. A positioning shaft is installed between one of the limiting plates and the sealing sleeve, and a buffer spring is installed between the other limiting plate and the sealing sleeve. A positioning rod for use with the buffer spring is installed on the outside of the other limiting plate.

[0014] In a preferred embodiment, a first limiting plate is installed on one side of the sealing sleeve, and an installation pin extending into the interior of the fixing frame is installed on the top of the first limiting plate. A second limiting plate is installed on the other side of the sealing sleeve. The first limiting plate and the installation pin work together to reinforce the fixing frame and the sealing sleeve during installation. Two pressure relief pipes are installed on the top of the sealing sleeve, and electric valves are installed on the outer sides of the top of each of the two pressure relief pipes. The electric valves are used to control the opening and closing of the pressure relief pipes, and the two pressure relief pipes are used for emergency pressure relief of the inside of the jet pipeline.

[0015] The technical effect of adopting the above-mentioned further solution is that the electric valve is used to control the opening and closing of the pressure relief pipeline, and the two pressure relief pipelines are used to perform emergency pressure relief treatment inside the jet pipeline.

[0016] In a preferred embodiment, a second sealing flange is installed at the end of the jet pipe away from the dust collection main pipe. A water inlet chamber is formed inside the second sealing flange. Equally spaced mounting grooves are formed on the outer side of the water inlet chamber and inside the second sealing flange, arranged in a ring shape inside the second sealing flange. A first sealing flange is installed at the end of the filter cover away from the jet pipe. Equally spaced positioning bolts extending into the filter cover are threaded onto the outer side of the first sealing flange, arranged in a ring shape inside the first sealing flange. The positioning bolts reinforce the filter cover and the first sealing flange, improving the sealing effect during use and facilitating disassembly and maintenance. A control panel is installed outside the dust collection main pipe. The electric valve is electrically connected to the control panel, which controls the operation of the electric valve, enabling the management of the electrical equipment.

[0017] The technical advantages of adopting the above-mentioned further solution are as follows: the positioning bolts are distributed in a ring shape inside the first sealing flange. The filter cover and the first sealing flange are reinforced and installed by the positioning bolts, which improves the sealing effect during use, facilitates disassembly and maintenance, and the control panel is used to control the operation of the electric valve, realizing the management of the power equipment.

[0018] In a preferred embodiment, the top of the Y-type filter is equipped with a sealing top cover, and the top of the sealing top cover is equipped with an inspection opening. The sealing top cover seals the top of the Y-type filter, and the inspection opening is opened to inspect the inside of the Y-type filter.

[0019] The technical effect of adopting the above-mentioned further solution is that the top of the Y-type filter is sealed by the sealing top cover, and the inside of the Y-type filter can be inspected by opening the maintenance opening.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] By setting up a dust removal main pipe, filter cover, jet pipeline, and first sealing flange, the fixing frame and sealing sleeve are reinforced during installation using a first limit plate and mounting pins. An electric valve controls the opening and closing of the pressure relief pipeline, and two pressure relief pipelines are used for emergency pressure relief inside the jet pipeline. A control panel controls the operation of the electric valve, enabling management of the electrical equipment. A sealing top cover seals the top of the Y-type filter, and the internal parts of the Y-type filter are inspected by opening the maintenance opening. Equally spaced mounting grooves are provided on the outer side of the water inlet chamber and inside the second sealing flange, arranged in a circular pattern inside the second sealing flange, to facilitate subsequent installation. The auxiliary installation includes positioning bolts arranged in a ring inside the first sealing flange. These bolts reinforce the filter cover and the first sealing flange, improving the sealing effect during use and facilitating disassembly and maintenance. Based on existing equipment, this invention adds a Y-type filter to the front end of the exhaust port of each pump. While the overall modification is minor, it addresses the root cause, fundamentally preventing solenoid valve clogging. Simultaneously, a sealing sleeve is installed on the outside of the jet pipeline to support the entire pipeline. The sealing sleeve is initially fixed using a positioning shaft and a buffer spring, and then further fixed using a first limiting plate and a mounting pin, improving the overall stability of the equipment during use.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figures 1-4 As shown, this embodiment provides a technical solution: a main drainage pump jet pipeline filtration device, including a dust suppression main pipe 1, with a filter cover 2 fitted on the outside of the dust suppression main pipe 1; a Y-type filter 21 is installed on the top of the filter cover 2, a filter cylinder 24 is installed inside the Y-type filter 21, a flow guide cylinder 25 is installed inside the filter cover 2, and a filter screen is installed inside the flow guide cylinder 25; a jet pipeline 3 is installed at one end of the dust suppression main pipe 1, a sealing sleeve 31 is fitted on the outside of the jet pipeline 3, a fixing frame 32 is installed on the outside of the sealing sleeve 31, and limit plates are installed on the top of the fixing frame 32 and on both sides of the sealing sleeve 31. A positioning shaft 38 is installed between one limit plate and the sealing sleeve 31, a buffer spring 39 is installed between the other limit plate and the sealing sleeve 31, and a positioning rod for use with the buffer spring 39 is installed on the outside of the other limit plate.

[0033] Going further, such as Figures 1-4 As shown: A first limiting plate 33 is installed on one side of the sealing sleeve 31, and an installation pin 34 extending into the interior of the fixing frame 32 is installed on the top of the first limiting plate 33. A second limiting plate 37 is installed on the other side of the sealing sleeve 31. The first limiting plate 33 and the installation pin 34 work together to reinforce the fixing frame 32 and the sealing sleeve 31 during installation. Two pressure relief pipes 35 are installed on the top of the sealing sleeve 31. Electric valves 36 are installed on the outer side of the top of the two pressure relief pipes 35. The electric valves 36 are used to control the opening and closing of the pressure relief pipes 35. The two pressure relief pipes 35 are used for emergency pressure relief of the inside of the jet pipe 3. A control panel is installed on the outside of the dust removal main pipe 1. The electric valves 36 are electrically connected to the control panel. The control panel is used to control the operation of the electric valves 36, realizing the management of the electrical equipment.

[0034] The above solutions also suffer from poor equipment sealing and protection, such as... Figures 1-3 As shown: In this solution, a sealing top cover 22 is installed on the top of the Y-type filter 21, and an inspection opening 23 is installed on the top of the sealing top cover 22. The top of the Y-type filter 21 is sealed by the sealing top cover 22, and the inside of the Y-type filter 21 is inspected by opening the inspection opening 23.

[0035] The above solutions also have the problem of difficulty in disassembling the equipment during maintenance, such as... Figures 1-3 As shown, in this scheme, a second sealing flange 42 is installed at the end of the jet pipe 3 away from the dust removal main pipe 1. A water inlet chamber is opened inside the second sealing flange 42. An equally spaced mounting groove is opened on the outside of the water inlet chamber and inside the second sealing flange 42. The mounting groove is distributed in a ring shape inside the second sealing flange 42. A first sealing flange 4 is installed at the end of the filter cover 2 away from the jet pipe 3. An equally spaced positioning bolt 41 extending into the filter cover 2 is threaded on the outside of the first sealing flange 4. The positioning bolt 41 is distributed in a ring shape inside the first sealing flange 4. The positioning bolt 41 is used to reinforce the filter cover 2 and the first sealing flange 4, which improves the sealing effect during use and facilitates disassembly and maintenance.

[0036] Working principle:

[0037] like Figure 1-4 As shown:

[0038] When in use, one end of the dust removal main pipe 1 is connected to the main drainage pump, and the first limiting plate 33 and the mounting pin 34 are used to reinforce the installation of the fixing frame 32 and the sealing sleeve 31.

[0039] The electric valve 36 is used to control the opening and closing of the pressure relief pipe 35. The two pressure relief pipes 35 are used for emergency pressure relief inside the jet pipe 3. The control panel is used to control the operation of the electric valve 36, realizing the management of electrical equipment. It does not use a large amount of electrical equipment and saves the overall use and installation costs.

[0040] The top of the Y-type filter 21 is sealed by the sealing top cover 22, and the inside of the Y-type filter 21 is inspected by opening the maintenance opening 23. The outside of the water inlet chamber and inside the second sealing flange 42 are provided with equally spaced installation grooves. The installation grooves are distributed in a ring shape inside the second sealing flange 42 to assist in the installation of other equipment.

[0041] The positioning bolts 41 are distributed in a ring shape inside the first sealing flange 4. The positioning bolts 41 are used to reinforce the filter cover 2 and the first sealing flange 4, which improves the sealing effect during use and facilitates disassembly and maintenance.

[0042] Based on existing equipment, this invention adds a Y-type filter 21 to the front end of the exhaust port of each pump body. The overall modification is small, but it achieves source control and fundamentally avoids the phenomenon of solenoid valve blockage.

[0043] Meanwhile, a sealing sleeve 31 is installed on the outside of the jet pipe 3 to support the jet pipe 3 as a whole. The sealing sleeve 31 is fixed at first by the positioning shaft 38 and the buffer spring 39, and then fixed at second by the first limiting plate 33 and the mounting pin 34, which improves the stability of the overall equipment during use.

[0044] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
