Abstract
Description
Technical Field
[0001] This invention relates to the field of foam storage technology, and more particularly to a storage device for foam production that is convenient to transport. Background Technology
[0002] The main raw material used in the production of expanding foam is polyether polyol, commonly known as white material, which has a pungent odor, is easily volatile, and is toxic.
[0003] Existing foam storage devices require maintaining a temperature between 5℃ and 30℃ during transportation to ensure good adhesive properties. However, considering that the temperature inside the transport vehicle is typically controlled by air conditioning, the cold air needs to circulate throughout the entire compartment to be effective. This necessitates the transport vehicle's air conditioning system to have high cooling power and maintain that high power for extended periods to achieve adequate cooling. This method results in significant energy consumption during storage operations. Furthermore, once the foam inside the storage tank is used up, it adheres to the inner wall of the tank, increasing the difficulty of cleaning and leading to incomplete cleaning, which affects subsequent use. Summary of the Invention
[0004] To overcome the drawbacks of existing methods that use air conditioning to regulate the temperature inside transport vehicles, where cold air needs to circulate throughout the entire compartment to be effective, resulting in high cooling power and prolonged maintenance of this power to achieve good cooling, and thus significant energy consumption during storage operations, this invention provides a convenient storage device for the production of foamed adhesives.
[0005] Technical Solution: A convenient storage device for producing expanded polyurethane foam includes a protective frame and a storage tank. The storage tank is detachably connected inside the protective frame. A discharge pipe is provided at the bottom of the storage tank, penetrating the bottom of the protective frame. A receiving cavity for accommodating power is provided at the bottom of the protective frame. The device also includes a threaded cap, a pump, a cooling pipe, and a suction pipe. A threaded cap is screwed onto the storage tank. The pump is fixedly connected inside the protective frame. A cooling pipe is fixedly connected to the output end of the pump, surrounding the surface of the storage tank. The other end of the cooling pipe is an exhaust pipe, which extends from the side of the protective frame and is connected to an activated carbon box. A suction pipe is connected to the input end of the pump, and the suction pipe has the ability to extend and retract. A suction head is provided at the end of the suction pipe. An air extraction hole is provided on the threaded cap, which allows the storage tank to be connected to the outside when the threaded cap is not completely unscrewed from the storage tank.
[0006] Furthermore, the cooling pipes are spiral-shaped.
[0007] Furthermore, it also includes a DD motor, an electric push rod, a connecting plate one, a connecting plate two, and a scraper rope; the DD motor is installed on the upper part of the storage tank, and a rotating part is provided in the middle of the DD motor; the rotating part is fixedly connected to the electric push rod; the telescopic part of the electric push rod is fixedly connected to the connecting plate one, and the connecting plate one has a cavity inside; several connecting plates two are fixedly connected to the end of the connecting plate one away from the electric push rod; a scraper rope is fixedly connected between two connecting plates two, and the scraper rope is in contact with the inner wall of the storage tank.
[0008] Furthermore, the second connecting plate is made of a deformable material.
[0009] Furthermore, a protective layer is provided on the surface of the scraping rope.
[0010] Furthermore, it also includes a water pipe and a spray pipe; a water pipe is fixedly connected to the upper part of the connecting plate and the water pipe communicates with the cavity inside the connecting plate; a spray pipe is fixedly connected to the end of the connecting plate away from the water pipe and the spray pipe communicates with the cavity inside the connecting plate.
[0011] Furthermore, the nozzle of the spray pipe is set at an angle downwards.
[0012] Furthermore, the upper part of the threaded cap is provided with an anti-slip grip pad.
[0013] Furthermore, a circular ring is provided on the outside of the protective frame.
[0014] Furthermore, the edges of the ring are chamfered.
[0015] The beneficial effects are as follows: This invention extends the suction pipe on the storage tank closest to the air conditioner to near the air conditioner's outlet, and then extends the suction pipes on the adjacent storage tanks to the exhaust pipe on the storage tank closest to the air conditioner. The suction pipes on the remaining storage tanks are arranged in the same manner. Then, all pumps are started simultaneously, so that the suction pipe on the storage tank closest to the air conditioner draws cold air into the cooling pipe. After passing through the cooling pipe, the cold air is discharged from the exhaust pipe. During this process, the cold air in the cooling pipe cools the storage tank. Subsequently, the suction pipes on the adjacent storage tanks draw away the cold air discharged from the exhaust pipe through the suction port. The drawn-out cold air enters the corresponding cooling pipe and cools the storage tank covered by the cooling pipe.
[0016] This invention involves bringing the suction tube close to the unscrewed part of the threaded cap, thereby continuously sucking air from around the threaded cap through the suction port of the suction tube. Then, the operator manually rotates the threaded cap and pulls it upwards, but does not completely remove the threaded cap from the storage tank, until the suction port is removed from the storage tank, connecting the inside of the storage tank with the outside. In this way, even if gas is discharged, the amount discharged per unit time will be relatively small due to the small size of the suction port, and the suction effect of the suction tube can promptly remove the discharged toxic gas.
[0017] This invention controls an external supply device to introduce cleaning agent or water into a water pipe and spray it from a nozzle onto the inner surface of a storage tank. At the same time, the nozzle is set to be tilted downwards so that the cleaning agent or water sprayed from the nozzle washes the dissolved foam downwards, causing the foam to quickly detach from the inner surface of the storage tank and be discharged from the discharge pipe into an external wastewater collection device.

Detailed Implementation
[0025] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0026] Example 1
[0027] A convenient storage device for the production of expanding foam, such as... Figure 1-3As shown, it includes a protective frame 1 and a storage tank 2; the storage tank 2 is detachably connected inside the protective frame 1; a discharge pipe 2001 is provided at the bottom of the storage tank 2, and the discharge pipe 2001 passes through the bottom of the protective frame 1; a receiving cavity for accommodating power is provided at the bottom of the protective frame 1.
[0028] It also includes a threaded cap 3, a pump 4, a cooling pipe 5, and a suction pipe 6; the storage tank 2 is screwed on with a threaded cap 3; the pump 4 is bolted inside the protective frame 1; the output end of the pump 4 is fixed and connected to the cooling pipe 5, which surrounds the surface of the storage tank 2, and the other end of the cooling pipe 5 is an exhaust pipe 5001, which extends out from the side of the protective frame 1 and is connected to an activated carbon box; the input end of the pump 4 is connected to the suction pipe 6, which has the ability to extend and shorten, and the end of the suction pipe 6 is provided with a suction head 6001; the threaded cap 3 is provided with a suction hole 3001, which allows the storage tank 2 to be connected to the outside when the threaded cap 3 is not completely unscrewed from the storage tank 2.
[0029] The cooling pipe 5 is spiral-shaped. By setting the cooling pipe 5 to a spiral shape, the cooling pipe 5 can more fully wrap around the storage tank 2, resulting in a better cooling effect on the storage tank 2.
[0030] The following describes how the above embodiments work:
[0031] During operation, the operator first unscrews the threaded cap 3 completely off the storage tank 2, then inserts the feed pipe of the external feeding device into the storage tank 2, and then fills the storage tank 2 with expanding foam until the predetermined storage amount is reached, without filling the entire storage tank 2. The operator then pulls out the feed pipe and re-screws the threaded cap 3 into the storage tank 2, ensuring that the vent 3001 is submerged in the storage tank 2 and does not connect to the outside. Finally, the filled storage tank 2 is moved to the transport vehicle.
[0032] Because the temperature of the expanding foam needs to be maintained between 5℃ and 30℃ during transportation to ensure good adhesive properties, it's important to consider that the temperature inside the transport vehicle is typically controlled by air conditioning. This requires the air conditioning system to circulate throughout the entire compartment to be effective, necessitating high cooling power and sustained high power for extended periods. This results in significant energy consumption during storage. Therefore, after loading, operators extend the suction pipe 6 on the storage tank 2 closest to the air conditioner to the air vent, aligning the suction head 6001 with the vent. To enhance the suction effect, the suction head 6001 can be shaped to resemble the vent, or a corrugated suction pipe can be used to prevent deformation from minor forces like vehicle vibrations. Alternatively, a suction cup or similar structure can be incorporated at the suction head 6001 to improve suction efficiency. The suction head 6001 of pipe 6 can be more stably attached to the air conditioner outlet. Then, pull the suction pipe 6 on the adjacent storage tank 2 to the exhaust pipe 5001 on the storage tank 2 closest to the air conditioner. The inner diameter of the suction pipe 6 can be set to be slightly smaller than the outer diameter of the exhaust pipe 5001. Then, directly and stably connect the two together. The suction pipes 6 on the remaining storage tanks 2 are arranged in the same way, so that all the cooling pipes 5, suction pipes 6, and exhaust pipes 5001 are connected end to end in sequence. Then control all Simultaneously, the pump 4 starts, and the power supply in the containment cavity provides power, causing the suction pipe 6 on the storage tank 2 closest to the air conditioner to draw cold air into the cooling pipe 5. After passing through the cooling pipe 5, the cold air is discharged from the exhaust pipe 5001. During this process, the cold air in the cooling pipe 5 cools down the storage tank 2. Subsequently, the suction pipe 6 on the adjacent storage tank 2 draws away the cold air discharged from the exhaust pipe 5001 through the suction port. The drawn cold air enters the corresponding cooling pipe 5 and cools down the storage tank 2 enclosed by the cooling pipe 5.
[0033] In this way, the cold air will quickly flow around the storage tank 2. And because most of the cold air is directly drawn away, areas in the transport vehicle without the storage tank 2 will hardly be cooled by cold air. Therefore, the efficiency of cold air utilization can be greatly improved. Areas that do not need cooling do not need to use cold air for cooling. This solves the problem that cold air needs to flow through the entire compartment to be effective, which would require the transport vehicle's air conditioning to have a high cooling power and maintain a high cooling power for a long time to achieve a good cooling effect. This method would result in a large energy consumption for storage operations.
[0034] Considering that during transportation, storage tank 2 will sway with the movement of the transport vehicle, causing the expanding foam inside to shake as well, resulting in the generation of more gas inside storage tank 2 and increasing the pressure inside. This means that when the threaded cap 3 is opened, the pressurized gas inside will be instantly ejected and diffused to a greater distance, increasing the probability of workers inhaling it and affecting their health; therefore, when it is necessary to use the expanding foam in storage tank 2, the discharge pipe 2001 should be connected to the external collection device, and then the suction pipe 6 should be pulled to... Figure 6 In the indicated state, the suction pipe 6 is brought close to the unscrewed part of the threaded cap 3, thereby continuously sucking the air around the threaded cap 3 from the suction port of the suction pipe 6. Then, the operator manually rotates the threaded cap 3 and pulls it upwards, but does not completely detach the threaded cap 3 from the storage tank 2, until the vent 3001 is removed from the storage tank 2, connecting the inside of the storage tank 2 with the outside. In this way, even if gas is discharged, the discharge volume per unit time will be relatively small due to the small size of the vent 3001, and the suction effect of the suction pipe 6 can promptly suck away the discharged toxic gas. Subsequently, an external suction device is connected to the discharge pipe 2001, and then the foaming adhesive in the storage tank 2 is sucked out by the external suction device. Subsequently, when the irritating toxic gas passes through the exhaust pipe 5001, the irritating toxic gas will be absorbed by the activated carbon box, thereby preventing the threaded cap 3 from being separated from the storage tank 2, which would cause the irritating toxic gas in the storage tank 2 to continuously be released into the air, and affect human health if inhaled.
[0035] Example 2
[0036] Based on Example 1, such as Figures 1-6 As shown, it also includes a DD motor 201, an electric push rod 202, a first connecting plate 203, a second connecting plate 204, and a scraper rope 205; the DD motor 201 is inserted through the center of the upper part of the storage tank 2, and a rotating part 20101 is provided in the middle of the DD motor 201; the electric push rod 202 is fixedly connected to the rotating part 20101; the telescopic part of the electric push rod 202 is fixedly connected to the first connecting plate 203, and the first connecting plate 203 has a cavity inside; two second connecting plates 204 are fixedly connected to the end of the first connecting plate 203 away from the electric push rod 202, and the scraper rope 205 is fixedly connected between the two second connecting plates 204, and the scraper rope 205 is in contact with the inner wall of the storage tank 2.
[0037] Connecting plate 204 is made of deformable material. Considering that there will be a small amount of firmly bonded expanding foam in the bucket after entering the cleaning stage, in order to prevent the use of connecting plate 204 from being affected by this firmly bonded expanding foam, connecting plate 204 is made of deformable material so that it will not be stuck by the firmly bonded expanding foam when it moves up and down under the action of connecting plate 1 203.
[0038] The surface of the scraper rope 205 is provided with a protective layer to reduce the degree of wear when it comes into contact with the inner wall of the storage tank 2.
[0039] It also includes a water pipe 206 and a spray pipe 207; the water pipe 206 is fixedly connected to the upper part of the connecting plate 203, and the water pipe 206 communicates with the cavity inside the connecting plate 203; the spray pipe 207 is fixedly connected to the end of the connecting plate 203 away from the water pipe 206, and the spray pipe 207 communicates with the cavity inside the connecting plate 203.
[0040] The nozzle of the spray pipe 207 is tilted downwards. By tilting the spray pipe 207 downwards, the acetone and water sprayed from the spray pipe 207 will wash the foam downwards, causing the foam to quickly separate from the inner side of the storage tank 2 and fall off.
[0041] The upper part of the threaded cap 3 is provided with a non-slip grip pad, which makes it easy to manually twist the threaded cap 3.
[0042] The protective frame 1 is symmetrically equipped with rings 1001 on the outside. By setting the rings 1001, hooks or ropes can be passed through the rings 1001 to facilitate hoisting work.
[0043] The edge of the 1001 ring is chamfered to reduce wear on the hook or rope.
[0044] The following describes how the above embodiments work:
[0045] After all the expanding foam is used up, some will adhere to the inner wall of storage tank 2. If not cleaned for a long time, the remaining expanding foam will harden and clump, increasing the difficulty of subsequent cleaning. Therefore, after all the expanding foam is used up, pour a softening and dissolving cleaning agent such as acetone or water into the external supply device. Then connect the external mixing device to the upper end of water pipe 206. Subsequently, control the DD motor 201 to drive the electric push rod 202, connecting plate one 203, connecting plate two 204, scraper rope 205, water pipe 206, and spray nozzle 207 to rotate counterclockwise with a top-down view as the reference. At the same time, control the electric push rod 202 to slowly push the connecting plate one 203, connecting plate two 204, scraper rope 205, water pipe 206, and spray nozzle 207 downwards. Control the external supply device to pass the cleaning agent or water into water pipe 206 and spray it out from spray nozzle 207 into storage tank 2. On the inner surface, the nozzle 207 is set to be tilted downwards so that the cleaning agent or water sprayed from the nozzle 207 will wash the dissolved foam downwards, so that the foam will quickly detach from the inner surface of the storage tank 2 and be discharged from the discharge pipe 2001 into the external sewage collection device. Considering that some slightly solidified foam is not easily removed by simply rinsing with water or cleaning agent, when the DD motor 201 drives the electric push rod 202, connecting plate one 203, connecting plate two 204, scraper rope 205, water pipe 206 and nozzle 207 to rotate, the scraper rope 205 scrapes the foam adhering to the inner wall of the storage tank 2, so that the foam is scraped off by the scraper rope 205. At the same time, the cleaning agent or water sprayed from the nozzle 207 will wash off the foam scraped off by the scraper rope 205, so as to avoid adhesion and accumulation on the scraper rope 205 and affect the subsequent cleaning effect.
[0046] The cleaning process requires one to two consecutive cycles. During this process, some stubborn adhesive clumps may remain that are not completely removed at once. These clumps can obstruct the connecting plate 204 and cause deformation damage to the non-deformable connecting plate 204. Therefore, by making the connecting plate 204 a deformable material, when the connecting plate 204 is squeezed against the firmly bonded foam inside the storage tank 2, the connecting plate 204 will deform. This will prevent the connecting plate 204 from being obstructed by the firmly bonded foam during its up-and-down movement driven by the connecting plate 203.
[0047] Considering that the filled storage container 2 is heavy and difficult to move onto the transport vehicle, an external hook is used to hook the ring 1001, and an external hoist is used to lift the protective frame 1 and the storage container 2 onto the transport vehicle. Existing technology generally uses ropes and slings to tie the storage container 2 for hoisting and transfer, which takes time to tie the slings and ropes to the storage container 2. This invention uses a hook-and-hold method for the protective frame 1, which is fast, stable, and has little impact on the storage container 2. The protective frame 1 can also play a protective role during the transfer and transportation of the storage container 2. At the same time, a chamfer is provided on the edge of the ring 1001 to reduce the wear on the hook or rope and extend its service life. In addition, an anti-slip grip pad is provided on the threaded cap 3 to facilitate manual twisting of the threaded cap 3.
[0048] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Therefore, all equivalent changes made to the content described in the claims of the present invention should be included within the scope of the claims of the present invention.
