Description

Technical Field

[0001] This invention relates to the field of fire extinguishing agent production technology, specifically a feeding machine for producing fluorine-free foam fire extinguishing agents. Background Technology

[0002] Fluorine-free foam extinguishing agent refers to an effective extinguishing agent that can extinguish flammable liquids. It mainly forms a coagulated foam floating layer on the liquid surface, which has a suffocating and cooling effect, and is widely used. The production of fluorine-free foam extinguishing agent involves many steps, including filling the foam extinguishing agent in the raw material tank into the foam fire extinguisher.

[0003] Currently, when using a foam liquid filling pump to add foam extinguishing agent from a raw material tank to a foam fire extinguisher, a connecting pipe needs to be inserted into the raw material tank. Then, the foam extinguishing agent is extracted through a hose and the foam liquid filling pump for filling. Because the raw material tank is quite tall and the connecting pipe is difficult to bend, it is inconvenient to pull the connecting pipe out of the raw material tank. Moreover, when the foam liquid filling pump is not in use, the length of the connecting pipe is too long, making it inconvenient to recycle and store it together with the foam liquid filling pump. After use, the connecting pipe is directly exposed to the air, which can easily lead to dust entering the inside of the connecting pipe during storage, causing blockage and affecting the subsequent use of the foam liquid filling pump. Summary of the Invention

[0006] The telescopic structure includes a connecting seat, which is fixedly connected to the side end of the foam liquid filling pump body. A fixing plate is detachably connected to the side end of the connecting seat. A hose is fixedly connected to the fixing plate. The hose and the connecting seat are inserted into each other. A connecting pipe is fixedly connected to the side end of the hose. A positioning ring is fixedly connected to the connecting pipe. A sliding ring is slidably connected to the connecting pipe.

[0009] Specifically, the disassembly structure includes a mounting plate, a mounting plate is fixedly connected to the side of the fixing plate, a positioning groove is provided in the mounting plate, a positioning block is slidably connected in the connecting seat, the positioning groove and the positioning block are inserted into each other, and a third spring is fixedly connected between the positioning block and the connecting seat.

[0010] Specifically, the side section of the mounting plate has an arc-shaped structure, and the overall cross-section of the positioning block has a convex shape.

[0011] Specifically, the limiting structure includes a rubber ring, and a rubber ring is detachably connected inside the sliding ring, with a limiting groove provided inside the rubber ring.

[0014] Specifically, the sealing structure includes a sealing plate, the side end of the sliding ring is detachably connected to the sealing plate, a sealing plug is fixedly connected to the sealing plate, and the sealing plug and the sliding ring are inserted into each other.

[0015] Specifically, the fixing structure includes a mounting ring, which is fixedly connected to the side end of the sealing plate. The mounting ring and the sliding ring are inserted into each other. A protrusion is fixedly connected to the mounting ring, and a groove is provided on the sliding ring.

[0016] The beneficial effects of this invention are:

[0017] (1) The feeding machine for producing fluorine-free foam extinguishing agent described in this invention, through a telescopic structure installed on the side end of the foam liquid filling pump body, facilitates the removal of the connecting pipe from the raw material tank of the foam extinguishing agent. A positioning structure limits and fixes the telescopic structure. That is, when it is necessary to add foam extinguishing agent to the foam extinguisher, firstly, the sliding ring is engaged on the raw material tank of the foam extinguishing agent, and then the positioning ring is pressed down, thereby driving the connecting pipe to slide within the sliding ring. Therefore, the connecting pipe can be inserted into the raw material tank. After fixing the positioning ring and the sliding ring together, the foam extinguishing agent in the raw material tank can be transported to the foam extinguisher through the connecting pipe. When the foam extinguishing agent in the raw material tank... After the agent is extracted, the positioning ring and sliding ring are released from their fixation. The spring force of the first spring allows the connecting tube to slide back out of the raw material barrel via the positioning ring, making it easy to remove the connecting tube from the raw material barrel. The length of the hose allows for material extraction from raw material barrels at different distances. When the positioning ring and sliding ring slide, after the fixing rod and the fixing groove in the fixing ring are inserted, the locking block engages with the fixing ring, thus limiting and fixing the positioning ring and sliding ring. When it is necessary to remove the fixing of the positioning ring and sliding ring, press the locking block down. After the locking block slides into the fixing rod, the fixing rod can be removed from the fixing groove, thereby releasing the positioning and fixing of the positioning ring and sliding ring.

[0018] (2) The feeding machine for producing fluorine-free foam fire extinguishing agent described in this invention can remove the hose and connecting pipe from the foam liquid filling pump body through the disassembly structure installed on the telescopic structure, thereby facilitating the storage and protection of the foam liquid filling pump body. The telescopic structure can be stably installed on the raw material tank through the limiting structure. That is, after the foam fire extinguishing agent is added, the positioning block is pressed down. When the positioning block and the positioning groove on the mounting plate are separated, the fixing plate can be removed from the side of the connecting seat, thereby disassembling the hose and connecting pipe for easy storage and placement. When the sliding ring is inserted into the discharge port of the raw material tank, the rubber ring installed in the sliding ring can prevent the sliding ring from falling off the top of the raw material tank when the sliding ring is inserted into the discharge port. The retaining ring fixed in the rubber ring can be engaged with the thread of the discharge port and the retaining ring to better position the sliding ring. The rubber plug fixed on the side of the rubber ring can be engaged with the sliding ring to disassemble and install the rubber ring.

[0019] (3) The feeding machine for producing fluorine-free foam fire extinguishing agent described in this invention can seal the connecting pipe on the foam liquid filling pump body when the foam liquid filling pump body is not in use through the sealing structure, so as to prevent garbage from entering the connecting pipe and causing blockage when not in use. The sealing structure can limit and fix the sealing structure through the fixing structure. That is, when not in use, the sealing plate is installed on the side end of the sliding ring. The connecting pipe can be protected by the sealing plug fixed on the side end of the sealing plate and the sliding ring, so as to prevent the connecting pipe from being blocked and affecting subsequent use. When the sealing plate is installed on the sliding ring, after the installation ring is inserted into the side end of the sliding ring, the installation ring and the sealing plate can be limited and fixed by the protrusion fixed on the installation ring and the groove provided on the sliding ring, so as to protect the connecting pipe.

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0030] like Figure 1 and Figure 7 As shown, the present invention provides a feeding machine for producing fluorine-free foam fire extinguishing agent, comprising a foam liquid filling pump body 1, a telescopic structure 2 installed on the side end of the foam liquid filling pump body 1, a positioning structure 3 installed on the telescopic structure 2, a disassembly structure 4 installed on the telescopic structure 2, a limiting structure 5 installed on the telescopic structure 2, a sealing structure 6 installed on the telescopic structure 2, and a fixing structure 7 installed on the sealing structure 6.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the telescopic structure 2 includes a connecting seat 201. The connecting seat 201 is fixedly connected to the side end of the foam liquid filling pump body 1. A fixing plate 202 is detachably connected to the side end of the connecting seat 201. A hose 203 is fixedly connected to the fixing plate 202. The hose 203 and the connecting seat 201 are inserted into each other. A connecting pipe 204 is fixedly connected to the side end of the hose 203. A positioning ring 205 is fixedly connected to the connecting pipe 204. A sliding ring 206 is slidably connected to the connecting pipe 204. A first spring 207 is fixedly connected between the positioning ring 205 and the sliding ring 206. When it is necessary to add foam extinguishing agent to the foam fire extinguisher, the sliding ring 206 is first engaged and installed on the original foam extinguishing agent. Press down on the material bucket and then press down on the positioning ring 205, which will cause the connecting pipe 204 to slide within the sliding ring 206. This allows the connecting pipe 204 to be inserted into the material bucket. After fixing the positioning ring 205 and the sliding ring 206 together, the foam extinguishing agent in the material bucket can be delivered to the foam fire extinguisher through the connecting pipe 204. When the foam extinguishing agent in the material bucket is completely extracted, release the fixing of the positioning ring 205 and the sliding ring 206. Through the elastic force of the first spring 207, the connecting pipe 204 can slide back to its original position and slide out of the material bucket through the positioning ring 205. This makes it easy to remove the connecting pipe 204 from the material bucket. The length of the hose 203 allows for material retrieval from material buckets at different distances.

[0032] Specifically, such as Figure 1 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the positioning structure 3 includes a fixing rod 301, which is fixedly connected to the positioning ring 205. A fixing ring 302 is fixedly connected to the sliding ring 206. The fixing ring 302 has a fixing groove 303 inside, and the fixing rod 301 is inserted into the fixing groove 303. A locking block 304 is slidably connected inside the fixing rod 301, and the locking block 304 abuts against the fixing ring 302. A second spring 305 is fixedly connected between the locking block 304 and the fixing rod 301. The side end cross-section of the fixing rod 301 is arc-shaped, and the overall cross-section of the locking block 304 is... The convex structure allows for the positioning and sliding of the positioning ring 205 and sliding ring 206 to be fixed when the fixing rod 301 is inserted into the fixing groove 303 in the fixing ring 302. The locking block 304 engages with the fixing ring 302, thus limiting and fixing the positioning ring 205 and sliding ring 206. When it is necessary to remove the fixing of the positioning ring 205 and sliding ring 206, the locking block 304 is pressed down. When the locking block 304 slides into the fixing rod 301, the fixing rod 301 can be removed from the fixing groove 303, thereby releasing the positioning and fixing of the positioning ring 205 and sliding ring 206.

[0033] Specifically, such as Figure 1 , Figure 2 and Figure 5 As shown, the disassembly structure 4 includes a mounting plate 401. The mounting plate 401 is fixedly connected to the side of the fixing plate 202. The mounting plate 401 has a positioning groove 402. The positioning block 403 is slidably connected to the connecting seat 201. The positioning groove 402 and the positioning block 403 are inserted into each other. A third spring 404 is fixedly connected between the positioning block 403 and the connecting seat 201. The side section of the mounting plate 401 has an arc-shaped structure. The overall cross-section of the positioning block 403 has a convex shape. After the foam extinguishing agent is added, the positioning block 403 is pressed down. When the positioning block 403 separates from the positioning groove 402 on the mounting plate 401, the fixing plate 202 can be removed from the side of the connecting seat 201, thereby allowing the hose 203 and the connecting pipe 204 to be disassembled for easy storage.

[0034] Specifically, such as Figure 4 and Figure 7 As shown, the limiting structure 5 includes a rubber ring 501. The rubber ring 501 is detachably connected inside the sliding ring 206. The rubber ring 501 has a limiting groove 502 inside. A retaining ring 503 is fixedly connected inside the rubber ring 501. Multiple retaining rings 503 are arranged in a linear distribution. A rubber plug 504 is fixedly connected to the side end of the rubber ring 501. The rubber plug 504 engages with the sliding ring 206. When the sliding ring 206 is inserted into the discharge port of the raw material barrel, the rubber ring 501 installed inside the sliding ring 206 can prevent the sliding ring 206 from falling off the top of the raw material barrel when it is inserted into the discharge port. The retaining ring 503 fixed inside the rubber ring 501 can engage with the thread of the discharge port to better position the sliding ring 206. The rubber plug 504 fixed to the side end of the rubber ring 501 engages with the sliding ring 206, allowing the rubber ring 501 to be disassembled and installed.

[0035] Specifically, such as Figure 4 and Figure 7 As shown, the sealing structure 6 includes a sealing plate 601. The sealing plate 601 is detachably connected to the side end of the sliding ring 206. A sealing plug 602 is fixedly connected to the sealing plate 601. The sealing plug 602 and the sliding ring 206 are inserted into each other. When not in use, the sealing plate 601 is installed on the side end of the sliding ring 206. By connecting the sealing plug 602 fixed to the side end of the sealing plate 601 with the sliding ring 206, the connecting pipe 204 can be protected to prevent the connecting pipe 204 from being blocked and affecting subsequent use.

[0036] Specifically, such as Figure 7As shown, the fixing structure 7 includes a mounting ring 701. The mounting ring 701 is fixedly connected to the side end of the sealing plate 601. The mounting ring 701 and the sliding ring 206 are inserted into each other. A protrusion 702 is fixedly connected to the mounting ring 701. A groove 703 is provided on the sliding ring 206. The protrusion 702 and the groove 703 engage. When the sealing plate 601 is installed on the sliding ring 206, after the mounting ring 701 is inserted into the side end of the sliding ring 206, the mounting ring 701 and the sealing plate 601 can be limited and fixed by the engagement of the protrusion 702 fixed on the mounting ring 701 and the groove 703 provided on the sliding ring 206, thereby protecting the connecting pipe 204.

[0037] In use, when adding foam extinguishing agent to the foam fire extinguisher, the sliding ring 206 is first engaged with the raw material container of the foam extinguishing agent. Then, the positioning ring 205 is pressed down, causing the connecting pipe 204 to slide within the sliding ring 206. This allows the connecting pipe 204 to be inserted into the raw material container. After fixing the positioning ring 205 and the sliding ring 206 together, the foam extinguishing agent in the raw material container can be delivered to the foam fire extinguisher through the connecting pipe 204. Once the foam extinguishing agent in the raw material container is depleted, the fixing of the positioning ring 205 and the sliding ring 206 is released. The elastic force of the first spring 207 allows the connecting pipe 204 to slide back to its original position and exit from the raw material container via the positioning ring 205. Therefore, it is easy to remove the connecting pipe 204 from the raw material barrel. The length of the hose 203 allows for material retrieval from barrels at different distances. When the positioning ring 205 and sliding ring 206 slide, after the fixing rod 301 and the fixing groove 303 in the fixing ring 302 are inserted, the locking block 304 engages with the fixing ring 302, which limits and fixes the positioning ring 205 and sliding ring 206. When it is necessary to remove the fixing of the positioning ring 205 and sliding ring 206, press down on the locking block 304. When the locking block 304 slides into the fixing rod 301, the fixing rod 301 can be removed from the fixing groove 303, thereby releasing the positioning and fixing of the positioning ring 205 and sliding ring 206. After adding the foam extinguishing agent, press down on the positioning block 403. When the positioning block 403 separates from the positioning groove 402 on the mounting plate 401, the fixing plate 202 can be removed from the side of the connecting seat 201, allowing the hose 203 and connecting pipe 204 to be disassembled for easy storage. When the sliding ring 206 is inserted into the discharge port of the raw material tank, the rubber ring 501 installed inside the sliding ring 206 prevents it from falling off the top of the raw material tank. The retaining ring 503 fixed inside the rubber ring 501 engages with the threads of the discharge port, better positioning the sliding ring 206. The rubber plug 504 on one side engages with the sliding ring 206, allowing for the disassembly and installation of the rubber ring 501. When not in use, the sealing plate 601 is installed on the side of the sliding ring 206. The sealing plug 602 fixed to the side of the sealing plate 601 and the sliding ring 206 are inserted to protect the connecting pipe 204, preventing blockage and ensuring subsequent use. When the sealing plate 601 is installed on the sliding ring 206, the mounting ring 701 is inserted into the side of the sliding ring 206. The protrusion 702 fixed on the mounting ring 701 and the groove 703 on the sliding ring 206 engage to limit and fix the mounting ring 701 and the sealing plate 601, thereby protecting the connecting pipe 204.
