Description

Technical Field

[0001] This utility model relates to the field of storage equipment technology, and in particular to a low-temperature storage stainless steel tank with an insulation layer. Background Technology

[0002] Low-temperature storage stainless steel tanks are designed for scenarios such as food cold chain, pharmaceutical reagents, and chemical raw materials.

[0003] Most existing low-temperature storage stainless steel tanks reduce temperature fluctuations and ensure the storage effect of materials by setting up insulation materials such as thermal insulation cotton. An existing patent (publication number: CN216853119U) discloses a lubricating oil storage tank with constant temperature storage function. By setting up an insulation bladder, an air pump is used to fill the air cavity inside the tank with air, thereby isolating the lubricating oil inside the tank from the outside environment, reducing heat transfer between the lubricating oil and the outside environment, thus helping the insulation shell to maintain a constant temperature for the tank. By setting a through groove, the oil inlet pipe, oil outlet pipe, and metal heat-conducting rod can be kept separate from the insulation bladder, thus keeping the insulation bladder in a closed state, thereby improving the heat insulation effect of the device.

[0004] To address the aforementioned issues, existing patents offer solutions, but their applicability to various scenarios is insufficient. In actual use, due to the lack of a cleaning structure, it is difficult to clean the tank, and material residues easily remain on the inner wall of the tank. Cleaning requires disassembling the tank or using special tools, which is cumbersome and difficult to thoroughly clean. This not only affects the purity of the stored different types of materials but may also cause the storage environment to deteriorate due to the deterioration of the residues, affecting the storage of subsequent materials and reducing the practicality of the device.

[0005] To address this, a low-temperature storage stainless steel tank with an insulation layer is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a low-temperature storage stainless steel tank with an insulation layer, which can solve the problem of insufficient adaptability of existing stainless steel storage tanks to various application scenarios. In actual use, due to the lack of a cleaning structure, it is difficult to clean the tank body, and material residues are easily left on the inner wall of the tank. Cleaning requires disassembling the tank body or using special tools, which is cumbersome and difficult to clean thoroughly. This not only affects the purity of the stored different types of materials, but may also cause the storage environment to deteriorate due to the deterioration of the residues, affecting the storage of subsequent materials and reducing the practicality of the device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a low-temperature storage stainless steel tank with an insulation layer, comprising a tank body, a partition layer at the top of the tank body, and an insulation component fixedly connected inside the partition layer; a cleaning component fixedly connected to the bottom of the tank body, and a discharge valve fixedly connected to the right side of the bottom of the tank body; the cleaning component includes a fixed bracket, a rotating motor fixedly connected to the top of the inner wall of the fixed bracket, and the fixed bracket fixedly connected to the bottom of the tank body; a rotating rod fixedly connected to the top of the rotating motor, the other end of the rotating rod extending into the interior of the tank body and fixedly connected to a U-shaped scraper, the surface of the U-shaped scraper contacting the inner wall of the tank body; a condenser fixedly connected to the left side of the top of the inner wall of the fixed bracket, and the heat-conducting rod of the condenser extending into the interior of the tank body.

[0008] Preferably, the insulation component includes a top cover plate, an air storage ring is fixedly connected to the bottom of the top cover plate, and a feed valve is fixedly connected to the top of the top cover plate. Arc-shaped airbags are fixedly connected to the four corners of the bottom of the air storage ring, and an electric air intake valve is fixedly connected to the top of the left side of the air storage ring.

[0009] Preferably, the surfaces of the four arc-shaped airbags are all covered with silicone rubber sponge.

[0010] Preferably, the surface of the top cover plate is threaded with a plurality of fixing bolts, and the ports of the fixing bolts extend into the interior of the tank.

[0011] Preferably, several cutting plates are fixedly connected to both sides of the inner wall of the U-shaped scraper, and the cutting plates are made of stainless steel.

[0012] Preferably, the surface of the fixed bracket is provided with a plurality of heat dissipation holes.

[0014] Preferably, the top of the tank is provided with a threaded hole for use with fixing bolts, and the surface of the tank is coated with an anti-corrosion coating.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting up an insulation component, this application can inflate the gas storage ring and the arc-shaped air bladder through an electric air inlet valve, causing the arc-shaped air bladder to expand and fill the gaps between the layers with the silicone rubber sponge on the surface. The gas insulation and the low thermal conductivity of the silicone rubber sponge form a double insulation barrier, reducing the heat exchange between the tank and the outside. At the same time, the top cover is tightly connected to the tank with fixing bolts, further enhancing the sealing performance and improving the practicality of the device. 2. This application, by setting up a cleaning component, can drive a rotating rod via a rotating motor to rotate a U-shaped scraper, which can scrape off residual material residue on the tank wall.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Please see Figure 1-5 The present invention provides the following technical solution: A low-temperature storage stainless steel tank with an insulation layer includes a tank body 1. A partition 2 is provided on the top of the tank body 1, and an insulation component 3 is fixedly connected inside the partition 2. A cleaning component 4 is fixedly connected to the bottom of the tank body 1, and a discharge valve 5 is fixedly connected to the right side of the bottom of the tank body 1. The cleaning component 4 includes a fixed bracket 401. A rotating motor 402 is fixedly connected to the top of the inner wall of the fixed bracket 401, and the fixed bracket 401 is fixedly connected to the bottom of the tank body 1. A rotating rod 403 is fixedly connected to the top of the rotating motor 402. The other end of the rotating rod 403 extends into the interior of the tank body 1 and is fixedly connected to a U-shaped scraper 404. The surface of the U-shaped scraper 404 contacts the inner wall of the tank body 1. A condenser 405 is fixedly connected to the left side of the top of the inner wall of the fixed bracket 401, and the heat-conducting rod of the condenser 405 extends into the interior of the tank body 1.

[0020] In this embodiment: the cooperation between the top cover plate 301 and the gas storage ring 302 restricts the movement of the top cover plate 301, allowing the gas storage ring 302 to be embedded in the partition 2, providing a stable installation base for the insulation component 3. The top cover plate 301 is tightly connected to the tank body 1 using fixing bolts 7, enhancing sealing to prevent leakage and ensuring the storage effect of the material. Simultaneously, the gas supply channel formed by the electric air inlet valve 305 inflates the gas storage ring 302 and the arc-shaped airbag 304, causing the arc-shaped airbag 304 to expand and, together with the silicone rubber sponge 6 on its surface, fill the gaps in the partition 2, forming a double insulation barrier, reducing heat loss and improving the practicality of the device. The cleaning component 4 is then rotated by the rotating motor 402, which drives the rotating rod 403 to rotate, causing the U-shaped scraper 404 to rotate along the inner wall of the tank 1. This scrapes away any remaining material residue on the tank wall. At the same time, the stainless steel cutting plate 8 on the inner wall of the U-shaped scraper 404 can break up materials that have solidified and clumped under low temperature conditions, ensuring the storage effect of the materials. The channel formed by the feed valve 303 and the discharge valve 5 can be used to flush the tank 1, avoiding cross-contamination, ensuring storage purity, and improving the ease of use of the cleaning component 4. Furthermore, under the action of the condenser 405, the temperature inside the tank 1 can be reduced in real time. Combined with the insulation component 3, a stable low temperature environment can be maintained, improving the practicality of the device.

[0021] Specifically, such as Figure 5 As shown, the insulation component 3 includes a top cover plate 301, an air storage ring 302 is fixedly connected to the bottom of the top cover plate 301, and a feed valve 303 is fixedly connected to the top of the top cover plate 301. Arc-shaped airbags 304 are fixedly connected to the four corners of the bottom of the air storage ring 302, and an electric air intake valve 305 is fixedly connected to the top of the left side of the air storage ring 302. Arc-shaped reinforcing plates 306 are fixedly connected between adjacent arc-shaped airbags 304, and the arc-shaped airbags 304 and the arc-shaped reinforcing plates 306 are located inside the partition layer 2.

[0022] Specifically, such as Figure 5As shown, the surfaces of the four arc-shaped airbags 304 are all covered with silicone rubber sponges 6.

[0023] Specifically, such as Figure 2 , Figure 5 As shown, the surface of the top cover plate 301 is threaded with several fixing bolts 7, and the ports of the fixing bolts 7 extend into the interior of the tank body 1.

[0024] In this embodiment: by tightening the fixing bolt 7, it passes through the top cover plate 301 and is threadedly connected to the tank body 1, which can firmly fix the top cover plate 301 to the top of the tank body 1, enhance the sealing performance between the tank body 1 and the top cover plate 301, prevent the leakage of low-temperature cold energy inside the tank or the infiltration of external heat. At the same time, in conjunction with the heat insulation performance of the silicone rubber sponge 6, it can effectively block the loss of heat, form a stable heat insulation space inside the tank body 1, and improve the ease of use of the heat insulation component 3.

[0025] Specifically, such as Figure 2 , Figure 4 As shown, several cutting plates 8 are fixedly connected to both sides of the inner wall of the U-shaped scraper 404, and the material of the cutting plates 8 is stainless steel.

[0026] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, the surface of the fixed bracket 401 is provided with several heat dissipation holes 9.

[0027] In this embodiment: the stirring structure formed by the cutting plate 8 enables the U-shaped scraper 404 to drive the cutting plate 8 to rotate smoothly, which can break up the solidified and lumped material in the low temperature environment, ensuring that the material is always in the appropriate size, avoiding blockage, and facilitating subsequent discharge. At the same time, the heat dissipation structure formed by the heat dissipation holes 9 can quickly dissipate the heat generated by the operation of the condenser 405 and the rotating motor 402, ensuring the stable operation of the cleaning component 4 and improving the stability of the device operation.

[0028] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, a controller 10 is fixedly connected to the front side of the tank 1, and the controller 10 is electrically connected to the insulation component 3, the cleaning component 4, and the discharge valve 5.

[0029] Specifically, such as Figure 2 , Figure 3 As shown, the top of the tank body 1 has a threaded hole 11 for use with the fixing bolt 7, and the surface of the tank body 1 is coated with anti-corrosion paint.

[0030] In this embodiment, the use of fixing bolts 7 and threaded holes 11 can form a threaded fastening structure, which can tightly connect the top cover plate 301 to the tank body 1, thereby enhancing the sealing performance of the device, preventing leakage, and ensuring the storage effect of materials. At the same time, under the action of controller 10, the operating parameters of the device can be set according to the actual situation to complete the cleaning of the tank body 1 and the storage and discharge of materials, thus improving the practicality of the device.

[0031] Working principle: When storing materials at low temperatures, first loosen the fixing bolts 7 to release the insulation component 3 from its fixed state, and remove the insulation component 3 from the tank body 1. Then, maintain and clean the tank body 1 and the insulation component 3. Next, align and push the arc-shaped reinforcing plate 306 with the partition 2 to ensure that the gas storage ring 302 is accurately embedded in the partition 2 at the top of the tank body 1. After it has moved into place, tighten the fixing bolts 7 again to move it through the top cover plate 301 into the threaded hole 11 at the top of the tank body 1 to lock it in place, so that the top cover plate 301 is tightly connected to the tank body 1. A sealed space is formed, laying the foundation for subsequent low-temperature storage. After completing the preliminary preparations, the operator sets the operating parameters of the device through the controller 10. First, the feed valve 303 is started, connecting the feed valve 303 with the inner cavity of the tank 1 to form a material conveying channel. The material to be stored is injected into the tank through the feed valve 303. After the material is added, the controller 10 closes the feed valve 303, cutting off the connection between the inside and outside of the tank. The condenser 405 is then started to continuously absorb heat from inside the tank. The absorbed heat is dissipated to the outside through the condenser 405's own heat dissipation structure, achieving the goal of cooling the interior of the tank 1. Once the temperature drops and reaches the target level, the electric air inlet valve 305 is activated to connect the gas storage ring 302 to the outside environment, forming an air supply channel. An external air pump is then connected to the electric air inlet valve 305. The air pump inflates the gas storage ring 302 and the arc-shaped air bladder 304, causing the arc-shaped air bladder 304 to expand and, together with the silicone rubber sponge 6 on its surface, fill the gaps in the partition layer 2. This utilizes the heat insulation properties of the gas and the low thermal conductivity of the silicone rubber sponge 6 to form a double insulation barrier, reducing heat exchange between the tank 1 and the outside environment. When the stored material needs to be retrieved, the controller 10 controls the discharge valve 5 to open. Under the influence of gravity, the material is discharged smoothly. After discharge, the tank 1 needs to be cleaned. The rotating motor 402 is started to drive the rotating rod 403 to rotate, which drives the U-shaped scraper 404 to rotate along the inner wall of the tank 1. This can scrape off the material residue remaining on the tank wall. At the same time, the external water source is connected to the feed valve 303, and the feed valve 303 and the discharge valve 5 are opened to form a water inlet-rinse-drainage channel, thereby completing the rinsing of the tank 1. The U-shaped scraper 404 completes the cleaning of the tank 1, avoiding cross-contamination of materials and ensuring the purity of the materials to be stored later.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
