Description

Technical Field

[0001] This application relates to the field of filter technology, specifically to a high-strength, impact-resistant bag filter. Background Technology

[0002] Bag filters are a type of multi-purpose filtration equipment with novel structure, small size, simple and flexible operation, energy saving, high efficiency, closed operation, and strong applicability. Inside the bag filter, the filter bag is supported by a metal mesh basket. The wastewater to be treated flows in through the inlet, is filtered by the filter bag, and flows out through the outlet. Impurities are intercepted in the filter bag, and the filter can be reused after the filter bag is replaced.

[0003] Chinese patent document CN223082454U discloses a bag filter, specifically its outer casing. The outer casing is covered by a top cover, and a rotating block is connected to the side of the top cover. A connecting shaft is inserted inside the rotating block, and both ends of the connecting shaft are connected to the inner wall of a fixed block via bearings. This patent, by incorporating a pull rod and an insert plate, allows the operator to manually pull the connecting block when the filter bag needs to be replaced. This allows the insert plate to be pulled out from the bottom of the top cover, and then the operator can rotate the top cover to open the top opening of the outer casing, thus effectively improving the efficiency of filter bag replacement.

[0004] However, the wastewater to be treated in the above-mentioned patent is directly transported into the outer shell, which will cause an impact on the filter bag. If the flow rate and pressure of the wastewater are large, it can easily lead to damage to the filter bag. Utility Model Content

[0005] In order to overcome the problem of short service life of filter bags caused by direct impact of sewage on filter bags in the prior art, this application provides a high-strength impact-resistant bag filter.

[0006] This application adopts the following technical solution: a high-strength impact-resistant bag filter, including a tank, the top of which is detachably provided with a cover, the upper part of which is provided with an inlet pipe and the bottom of which is provided with an outlet pipe, the inner side of which is provided with an mounting plate, the mounting plate being provided with a plurality of filter bags, one end of which is located on the outer side of the tank and the other end extending to the inner side of the tank, the end of which is located inside the tank being closed, and the inlet pipe being provided with a plurality of through holes, the through holes being disposed away from the mounting plate;

[0007] The top of the mounting plate is provided with an umbrella-shaped guide plate. There is a distance between the outer edge of the guide plate and the inner wall of the tank. The guide plate and the mounting plate are connected by a support rod.

[0008] Optionally, the mounting plate is provided with a plurality of mounting holes, and the filter bag is installed in the mounting holes, all of which are located below the guide plate.

[0009] Optionally, the filter bag includes a connector and a bag body, the connector being adapted to be disposed in the mounting hole, and there is a gap between the lower part of the connector and the inner wall of the mounting hole;

[0010] The bag is fitted over the lower part of the connector and is secured within the gap.

[0011] Optionally, the lower part of the connector is provided with at least one pair of grooves, the pair of grooves are spaced apart along the height direction of the connector, and the outer side of the bag body is provided with elastic rings, the number of elastic rings being the same as the number of grooves, the elastic rings being used to tighten the bag body and cause the bag body to bend toward the inside of the grooves.

[0012] Optionally, the mounting hole is a stepped hole, the upper part of the connector is disposed on the stepped surface of the mounting hole, and the top of the connector is flush with the top of the mounting hole.

[0013] Optionally, the lower outer diameter of the connector gradually decreases from top to bottom, the elastic ring is provided in a one-to-one correspondence with the groove, and the outer wall of the elastic ring is provided with a protrusion.

[0014] When the connector is pressed into the mounting hole, the protrusion is clamped between the inner wall of the mounting hole and the bag body and undergoes elastic deformation.

[0015] In summary, this application includes the following beneficial technical effects:

[0016] 1. The inlet pipe is closed at one end inside the tank and has a through hole facing away from the mounting plate. This way, the sewage to be treated will not directly impact the filter bag after entering the tank, avoiding the sewage acting on the filter bag with a large impact force. This greatly reduces the possibility of the filter bag being damaged by impact, and thus effectively reduces the maintenance cost of the equipment and the frequency of filter bag replacement.

[0017] 2. When wastewater flows out of the inlet pipe, it first comes into contact with the baffle plate. The baffle plate guides the wastewater entering the tank, causing it to disperse and flow along the surface of the baffle plate instead of directly hitting the filter bag. This further buffers the impact of the wastewater on the filter bag and extends its service life. Attached Figure Description

[0026] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] like Figure 1-7 As shown, a high-strength, impact-resistant bag filter includes a tank 1, a cover 2, an inlet pipe 11, and a drain pipe 12. The cover 2 is detachably mounted on the top of the tank 1. The inlet pipe 11 is located on the upper part of the tank 1, and the drain pipe 12 is located on the bottom of the tank 1. An mounting plate 3 is also provided inside the tank 1, on which several filter bags 4 can be mounted. The inlet pipe 11 is used to transport wastewater to be treated. One end of the inlet pipe 11 is located outside the tank 1 and connected to the wastewater source, while the other end extends into the inside of the tank 1 and is closed. When wastewater is transported into the tank 1 through the inlet pipe 11, it flows downwards and enters the filter bags 4. After being filtered by the filter bags 4, it is discharged from the drain pipe 12, thus achieving wastewater filtration treatment.

[0028] The end of the inlet pipe 11 is closed, and the top of the inlet pipe 11 is provided with several through holes 110. The through holes 110 are positioned away from the mounting plate 3, meaning that the through holes 110 can be located at the top of the inlet pipe 11 or on the side wall of the inlet pipe 11. In this way, after the sewage is discharged from the through holes 110, it will first impact the cover 2 or the side wall of the tank 1, thereby avoiding direct impact on the filter bag 4. This effectively improves the service life of the filter bag 4 without affecting the filtration operation. Furthermore, a guide plate 5 is also provided inside the tank 1. The guide plate 5 is umbrella-shaped and is positioned above the mounting plate 3. There is a distance between the outer edge of the guide plate 5 and the inner wall of the tank 1. The guide plate 5 can be connected to the mounting plate 3 by a support rod 50, which can be welded or bolted between the guide plate 5 and the mounting plate 3. The function of the guide plate 5 is to disperse and guide the sewage flowing out of the inlet pipe 11, so that the sewage flows evenly to the filter bag 4, thereby minimizing the impact on the filter bag 4 and effectively extending the service life of the filter bag 4.

[0029] The filter bag 4 includes a connector 41 and a bag body 42. The connector 41 is adapted to fit within a mounting hole 30, which is a stepped hole. The upper part of the connector 41 is located on the stepped surface of the mounting hole 30, and the top of the connector 41 is flush with the top of the mounting hole 30. There is a gap between the lower part of the connector 41 and the inner wall of the mounting hole 30. The bag body 42 is fitted onto the lower part of the connector 41 and secured within the gap. The lower part of the connector 41 has at least one pair of grooves 410, which are spaced apart along the height direction of the connector 41. The outer side of the bag body 42 has elastic rings 43, the number of which is the same as the number of grooves 410. The elastic rings 43 are used to tighten the bag body 42 and cause the bag body 42 to bend towards the inside of the grooves 410. The elastic rings 43 can be rubber rings or silicone rings, and have good elasticity. The lower outer diameter of the connector 41 gradually decreases from top to bottom. Elastic rings 43 and grooves 410 are correspondingly arranged. The outer wall of the elastic ring 43 has a protrusion 430. When the connector 41 is pressed into the mounting hole 30, the protrusion 430 is clamped between the inner wall of the mounting hole 30 and the bag body 42, resulting in elastic deformation. In other words, during the installation of the filter bag 4, the bag body 42 is first placed on the lower part of the connector 41, at which point the bag body 42 covers the groove 410. Then, the elastic ring 43 is placed on the bag body 42, with the elastic ring 43 on the outside of the groove 410. Thus, under the elastic tightening action of the elastic ring 43, the bag body 42 is pressed into the groove 410, effectively improving the connection reliability of the bag body 42 on the connector 41. After the filter bag 4 is assembled, it can be placed facing the mounting hole 30. Because the outer wall of the elastic ring 43 has a protrusion 430, which is also annular, and the lower outer diameter of the connector 41 gradually decreases from top to bottom, the connector 41 can easily align with the mounting hole 30 and smoothly insert into it. When the protrusion 430 contacts the inner wall of the mounting hole 30, the filter bag 4 cannot move downwards by its own weight. At this time, pressing the top of the connector 41 forcefully causes the inner wall of the mounting hole 30 to exert a squeezing effect on the protrusion 430 and the elastic ring 43, causing the protrusion 430 and the elastic ring 43 to undergo elastic deformation. This allows the connector 41 to reliably lock into the mounting hole 30, resulting in simple operation and good fixing effect.

[0030] The implementation principle of this embodiment is as follows: the design of the inlet pipe 11 with the through hole 110 facing away from the mounting plate 3 and the umbrella-shaped guide plate 5 effectively reduces the direct impact of sewage on the filter bag 4, thus effectively extending the service life of the filter bag 4. The cooperation between the connector 41, the elastic ring 43, and the protrusion 430 enables the filter bag 4 to be installed quickly and reliably in the mounting hole 30, enhancing the connection stability between the filter bag 4 and the mounting plate 3 and improving the overall strength of the filter bag 4.

[0031] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
