[0014] Compared with the prior art, this utility model provides a filtration device for producing anti-clogging foam fire extinguishing agents, which has the following beneficial effects:

[0015] This anti-clogging foam fire extinguishing agent production filtration device, through a slag trough assembly and a high-pressure flushing water pipe, allows for easy cleaning of the filter screen. When cleaning is required, a motor is started to rotate the drum-type filter screen structure. Simultaneously, water enters through the high-pressure flushing water pipe. Under high pressure, water flows through several sets of outlet holes onto the surface of the drum-type filter screen structure. The brushes on the edge of one side plate of the slag trough clean the surface of the drum-type filter screen structure, trapping impurities, suspended solids, and particles into the slag trough. The water flow then carries these impurities, suspended solids, and particles to the drain pipe for discharge, achieving timely cleaning and preventing clogging. This avoids wear or blockage caused by these impurities, suspended solids, and particles, reducing equipment failure and maintenance costs, and ultimately improving the purity and quality of the product.

[0016] This anti-clogging foam fire extinguishing agent production filtration device, through the installation of a shock-absorbing support assembly, transmits the vibrations generated during equipment operation to the surface of the pipe support frame when mechanical vibration needs to be reduced. This causes the pipe support frame to vibrate, which in turn causes the support plate to press down. Simultaneously, the sliding sleeve slides downward, causing the support spring to be compressed and stretched by the pressure impact of the support plate. The damping hydraulic rod suppresses the vibration when the support spring rebounds, thereby effectively absorbing and mitigating these vibrations, extending the service life of the equipment, and reducing maintenance and replacement costs.

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.

[0023] Please see Figures 1-4 This utility model discloses a filtration device for producing anti-clogging foam fire extinguishing agent, including a tank body 1 and a rotary drum filter structure 2 disposed inside the tank body 1. A high-pressure flushing water pipe 3 is sleeved on the surface of the tank body 1. A fixed partition 4 is disposed inside the tank body 1, and a slag trough assembly 5 is fixedly connected inside the fixed partition 4. The slag trough assembly 5 includes a slag trough 501 and a drain pipe 502, which is sleeved inside the tank body 1. An input pipe 6 is disposed at the bottom of the tank body 1, and an output pipe 7 is connected through the bottom of the tank body 1. The bottom of the input pipe 6 is connected through to... A connecting pipe 8 is connected, and pipe support frames 9 are sleeved at both ends of the connecting pipe 8.

The shock-absorbing bracket assembly 10 includes a support plate 1001, a positioning seat 1002, a support spring 1003, a sliding sleeve 1004, and a damping hydraulic rod 1005. A rotating assembly 11 is set at one end of the drum-type filter structure 2. The rotating assembly 11 includes a steering gear 1101, a motor 1102, and a transmission rod 1103. The transmission rod 1103 is fixedly connected to one end of the drum-type filter structure 2.

[0024] Specifically, the slag trough assembly 5 includes a slag trough 501 fixedly connected inside the fixed partition 4, and a drain pipe 502 is connected through one end of the slag trough 501, which is connected through to one side of the tank body 1.

[0025] In this embodiment, the intercepted impurities, suspended solids and particles are diverted into the slag trough 501, and the impurities, suspended solids and particles are transported to the drain pipe 502 by the water flow and discharged. The slag trough assembly 5 effectively diverts the intercepted impurities, suspended solids and particles into the slag trough 501.

[0026] Specifically, the shock absorber bracket assembly 10 includes a support plate 1001 fixedly connected to the bottom of the pipe support frame 9. Two sets of support springs 1003 are fixedly installed at the bottom of the support plate 1001. A damping hydraulic rod 1005 is sleeved inside the support spring 1003. A sliding sleeve 1004 is fixedly connected to the bottom of the support plate 1001. A positioning seat 1002 is fixedly connected to the bottom of the sliding sleeve 1004.

[0027] In this embodiment, mechanical vibration is transmitted to the pipe support frame 9, and the vibration of the pipe support frame 9 causes the support plate 1001 to press down. At the same time, the sliding sleeve 1004 slides down, so that the support spring 1003 is compressed and stretched by the pressure impact of the support plate 1001. The damping hydraulic rod 1005 suppresses the vibration when the support spring 1003 rebounds. Through the setting of the shock absorber bracket assembly 10, these vibrations are effectively absorbed and mitigated.

[0028] Specifically, the rotating assembly 11 includes a steering device 1101 fixedly connected to one side of the tank body 1, a motor 1102 is provided at the bottom of the steering device 1101, and a transmission rod 1103 is connected to one side of the steering device 1101.

[0029] In this embodiment, the starter motor 1102 drives the steering gear 1101 to run, and at the same time drives the transmission rod 1103 to rotate, so that the drum filter structure 2 rotates. Through the setting of the rotating component 11, the effect of driving the drum filter structure 2 to rotate synchronously is achieved.

[0030] Specifically, the surface of the high-pressure flushing water pipe 3 is provided with several sets of water outlet holes equidistantly in the axial direction, and the other end of the high-pressure flushing water pipe 3 is fitted with an installation piece 12.

[0031] In this embodiment, under high pressure water inlet, the high-pressure flushing water pipe 3 flushes water through several sets of water outlet holes to the surface of the drum filter structure 2, so that the impurities, suspended matter and particles intercepted on the surface of the drum filter structure 2 are intercepted and flowed into the slag tank 501, thereby achieving the effect of timely cleaning and preventing blockage.

[0032] Specifically, the mounting plate 12 is fixedly installed on one side of the fixed partition 4, the fixed partition 4 is fixedly installed on the inner wall of the tank 1, and control valves 13 are provided on the surfaces of the input pipe 6 and the output pipe 7.

[0033] In this embodiment, the mounting plate 12 is fixedly installed on one side of the fixed partition 4 to enhance the stability of the high-pressure flushing water pipe 3. The fixed partition 4 is fixedly installed on the inner wall of the tank 1. The control valve 13 is used to control the entry and exit of the input pipe 6 and the output pipe 7.

[0034] Specifically, a sealing plate 14 is inserted into one side of the tank body 1, and a rotating groove is opened inside one side of the sealing plate 14. The rotating drum filter structure 2 is rotatably connected to the inside of the rotating groove.

[0035] In this embodiment, a sealing plate 14 is inserted into one side of the tank 1. The sealing plate 14 facilitates the fixed connection of the rotating assembly 11. A rotating groove is provided inside one side of the sealing plate 14, so that the drum-type filter structure 2 is rotatably connected to the inside of the rotating groove.

[0036] Specifically, the top of the pipe support frame 9 is threadedly connected to an upper pipe support 16. Both the upper pipe support 16 and the pipe support frame 9 have two sets of threaded mounting holes on both sides, and threaded bolts 15 pass through the inside of the threaded mounting holes.

[0037] In this embodiment, the top of the pipe support frame 9 is threadedly connected to an upper pipe support 16. Both the upper pipe support 16 and the pipe support frame 9 have two sets of threaded mounting holes on both sides. The threaded holes facilitate the rotation and installation of the threaded bolt 15 inside. The threaded bolt 15 passes through the inside of the mounting hole. The setting of the pipe support frame 9 achieves the stability of the connecting pipe 8.

[0038] The working principle and usage process of this utility model are as follows: When the filter screen needs to be cleaned, the motor 1102 is started to drive the drum-type filter screen structure 2 to rotate; at the same time, the high-pressure flushing water pipe 3 starts to enter water. Under high pressure, the water is flushed to the surface of the drum-type filter screen structure 2 through several sets of water outlet holes. Under the action of the brush on the edge of the side plate of the sludge tank 501, the impurities, suspended matter and particles intercepted on the surface of the drum-type filter screen structure 2 are intercepted into the sludge tank 501. The impurities, suspended matter and particles are transported to the drain pipe 502 for discharge by the water flow.

[0039] When it is necessary to reduce mechanical vibration, the vibration generated by the operation of the equipment during the production process is transmitted to the pipe support frame 9. The vibration of the pipe support frame 9 causes the support plate 1001 to press down, and at the same time the sliding sleeve 1004 slides down, so that the support spring 1003 is compressed and stretched by the pressure impact of the support plate 1001. The damping hydraulic rod 1005 suppresses the vibration when the support spring 1003 rebounds.

[0040] In summary, this anti-clogging foam fire extinguishing agent production filtration device, through the slag tank assembly 5 and the high-pressure flushing water pipe 3, achieves the effect of timely cleaning and preventing clogging, avoiding wear or blockage caused by these impurities, suspended matter and particles, thus preventing equipment failure and maintenance costs, and ultimately improving the purity and quality of the product. Through the shock-absorbing bracket assembly 10, it effectively absorbs and mitigates these vibrations, extends the service life of the equipment, and reduces maintenance and replacement costs.
