Low-liquid-level anti-vortex fire-fighting filter

Abstract

The utility model belongs to the technical field of fire-fighting equipment, and particularly relates to a low-liquid-level anti-vortex fire-fighting filter which comprises a supporting seat, the bottom of the supporting seat is in threaded connection with a filter cartridge, a shell is fixed to the top of the supporting seat, and through grooves formed in the top of the supporting seat in an annular array mode are formed in the lower portion of the shell. By arranging the supporting seat, the filter cartridge, the shell, the through groove, the anti-swirling assembly, the pipeline, the annular plate and the floating plate assembly, water flow entering the shell can be separated and blocked by utilizing the anti-swirling assembly arranged at the top of the supporting seat in the process of using the fire-fighting filter, so that a swirling phenomenon can be prevented from being generated in the shell, and the service life of the fire-fighting filter is prolonged. The filter can float on the water surface through the arranged floating plate assembly, and when the water surface descends, the filter can synchronously descend along with the water surface, so that the filter cartridge is always in the water, and the situation that the water suction pressure of a water pump is insufficient due to the fact that the filter sucks a large amount of air is avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a low-liquid-level anti-vortex fire-fighting filter. Background Art

[0002] The fire filter is installed at the bottom of the fire pump's suction pipe. It is mainly used in fire trucks that use natural water sources to extinguish fires during firefighting and rescue, and in scenes such as using fire trucks to drain water and drain water from rivers. It is used to prevent debris and weeds in the water from being sucked into the water filter head of the pump body. Under normal circumstances, it can meet the suction and discharge requirements of the fire pump. However, during the use of current fire filters, when they are operating at a low water level, water vortices are easily generated inside the filter net, and the filter will be difficult to be submerged in water and exposed to the air. At this time, a large amount of air will enter the water suction port, resulting in insufficient water suction pressure of the water suction pump, affecting work efficiency. Therefore, we proposed a low-level anti-vortex fire filter to solve the above problems. Utility Model Content

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the utility model provides a low liquid level anti-vortex fire filter, which has the following beneficial effects:

[0015] The utility model provides a support seat, a filter cartridge, a shell, a through groove, an anti-vortex component, a pipe, an annular plate and a floating plate component. During the use of the fire filter, the anti-vortex component arranged on the top of the support seat can be used to separate and block the water flow entering the shell, thereby preventing the shell from generating a vortex phenomenon.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a low-liquid-level anti-vortex fire filter proposed in an embodiment of the utility model comprises a support seat 1, a filter cartridge 2 is threadedly connected to the bottom of the support seat 1, a toggle block 9 is fixed on the surface of the filter cartridge 2 in an annular array, when the filter cartridge 2 needs to be cleaned, it is convenient for the staff to separate the filter cartridge 2 from the support seat 1, a shell 3 is fixed on the top of the support seat 1, a through groove 4 is arranged in an annular array on the top of the support seat 1 below the shell 3, an anti-vortex component 5 is arranged on the top of the support seat 1, a pipe 6 is fixed inside the through hole opened on the top of the shell 3, a flange 10 is fixed on the top of the pipe 6, a sealing gasket 11 is fixed on the top of the flange 10, and the flange 10 is arranged to facilitate the connection and fixation of the pipe 6 with the water inlet pipe of the pump body. The sealing gasket 11 can enhance the sealing performance between the two connecting and fixing flanges 10 to avoid water leakage. An annular plate 7 is fixed on the surface of the shell 3, and a floating plate assembly 8 is arranged on the top of the annular plate 7. When using this fire filter, the pipe 6 can be connected and fixed to the water inlet pipe of the fire pump, and then the filter can be placed in the water. Under the action of the floating plate assembly 8, the filter can float on the water surface as a whole. When it floats on the water surface, the filter cartridge 2 will always be in the water. When absorbing water, the water filtered by the filter cartridge 2 will enter the interior of the shell 3 through the through groove 4. When the water flow enters the interior of the shell 3, the anti-vortex assembly 5 can separate the water flow to avoid it from generating vortex flow, and then the water entering the interior of the shell 3 will enter the interior of the pipe 6.

[0025] like Figure 5 As shown, there is another way of the floating plate assembly 8 that can float the support seat 1 in the utility model, which mainly includes a support frame 12 fixed on the annular plate 7, and a fixing block 13 is fixed on the top of the support frame 12 in an annular array, and an annular airbag 14 is placed on the top of the support frame 12, and a fixing belt 15 is fixed on the top of the annular plate 7 in an annular array. When in use, the set annular airbag 14 can be used to float the filter as a whole on the water surface, and the set fixing belt 15 and the fixing block 13 are used to cooperate to limit and fix the annular airbag 14.

The surface of the guide block 501 is provided with an arc groove 504 in a circular array. When in use, after the water flows through the through groove 4 into the interior of the shell 3, the partition plate 502 and the guide block 503 cooperate to block and prevent the incoming water from swirling.

[0027] like Figure 1 and Figure 2 As shown, in some embodiments, the floating plate assembly 8 includes limiting columns 801 fixed in an annular array on the top of the annular plate 7, and the surfaces of the limiting columns 801 are all plugged with arc plate assemblies 802. The surface of the pipe 6 is threadedly connected with a limiting seat 803, and the bottom of the limiting seat 803 fits with the top of the four arc plate assemblies 802. When in use, the arc plate assemblies 802 can be respectively plugged into the surfaces of the limiting columns 801, and then the limiting seats 803 can be unscrewed to limit the four arc plate assemblies 802. At this time, the installation of the arc plate assembly 802 can be completed. When it needs to be removed, the limiting seat 803 can be rotated to release the restriction and it can be removed.

[0028] like Figure 2 As shown, in some embodiments, the arc plate assembly 802 includes a hollow aluminum plate 80201 inserted into the surface of the limiting column 801, and a foam plate 80202 is placed inside the hollow aluminum plate 80201. Since the foam plate 80202 is light in weight, it can support the entire filter to float. By arranging a hollow aluminum plate 80201 on the outside of the foam plate 80202, the foam plate 80202 can be protected.
