DETAILED DESCRIPTION

[0025] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0026] See also Figure 1-5 The utility model provides a technical solution: a material storage tank for the production of polyurethane foam sealant, comprising an inner tank body 2, the surface of the inner tank body 2 is fixedly connected to an outer tank body 1, and the surface of the outer tank body 1 is provided with a through hole 3 that penetrates the surface of the outer tank body 1, so that the space between the outer tank body 1 and the inner tank body 2 can be connected to the outside, thereby ensuring the normal dissipation of heat between the outer tank body 1 and the inner tank body 2, and further ensuring the use effect of the device.

[0027] Furthermore, a feed pipe 5 penetrating the surface of the outer tank body 1 is fixedly connected to the surface of the outer tank body 1, and a bent discharge pipe 4 is fixedly connected to the bottom of the inner tank body 2. The bottom of the inner wall of the inner tank body 2 is inclined, and the feed end of the discharge pipe 4 is located at the lowest point of the bottom of the inner wall of the inner tank body 2, thereby ensuring that the polyurethane white material in the inner tank body 2 can be gathered at the feed end of the discharge pipe 4 during discharge, thereby ensuring the completeness of the discharge of the device and reducing the residue of polyurethane white material in the inner tank body 2.

[0028] A spiral tube 7 is fixedly connected to the surface of the inner tank body 2, and the lower end of the spiral tube 7 is fixedly connected to one end of the feed tube 5 located inside the outer tank body 1. An injection tube 8 that penetrates the surface of the inner tank body 2 is fixedly connected to the upper part of the inner tank body 2, and one end of the injection tube 8 located outside the inner tank body 2 is fixedly connected to the upper end of the spiral tube 7, thereby ensuring that the polyurethane white material injected in the feed tube 5 can be smoothly injected into the inner tank body 2, thereby ensuring the smooth progress of the feeding work.

[0029] Secondly, the material of the spiral tube 7 is aluminum alloy, so that the heat emitted by the polyurethane white material in the spiral tube 7 can be absorbed more quickly, effectively avoiding the situation where the temperature of the inner tank body is too high due to the accumulation of heat in the polyurethane white material during injection, thereby improving the use effect of the device. At the same time, the setting of the outer tank body 1 can protect the spiral tube 7, avoid damage to the spiral tube 7 caused by external collisions, and improve the service life of the device.

[0030] Furthermore, a pump body 6 is provided at one end of the feed pipe 5 away from the inner tank body 2, and the discharge end of the pump body 6 is connected to the feed pipe 5 to provide sufficient energy for the injection of the polyurethane white material. The inner tank body 2 is internally rotatably connected to a rotating shaft 10 that passes through the bottom of the inner tank body 2, and the upper end of the rotating shaft 10 is fixedly connected to a first turbine blade 9, and the first turbine blade 9 corresponds to the discharge end of the injection pipe 8, thereby ensuring that when the injection pipe 8 is injecting material into the inner tank body 2, it can use the impact of the polyurethane white material on the first turbine blade 9 to smoothly drive the first turbine blade 9 to rotate, thereby ensuring the smooth operation of the device.

[0031] The surface of the rotating shaft 10 is fixedly connected with a scraper 11 whose horizontal cross-section is equidistantly arranged in a circle. The scraper 11 is inclined. The surface of the scraper 11 is slidably connected to the inner wall of the inner tank body 2. The bottom of the inner tank body 2 is fixedly connected with a fixed box 12. The lower end of the rotating shaft 10 is located inside the fixed box 12. The inside of the discharge pipe 4 is rotatably connected with a mounting shaft 13 that penetrates the surface of the discharge pipe 4. The end of the mounting shaft 13 away from the discharge pipe 4 penetrates the inside of the fixed box 12 and is rotatably connected to the inside of the fixed box 12. The mounting shaft 13 is located inside the fixed box 12 and is fixedly connected to a bevel gear 14 at one end. The end of the rotating shaft 10 located inside the fixed box 12 is also fixedly connected to the bevel gear 14. The two bevel gears 14 are meshed with each other. The end of the mounting shaft 13 located inside the discharge pipe 4 is fixedly connected with a second turbine blade 15, so that the device can be used to impact the second turbine blade 15 during discharging to drive the mounting shaft 13 to rotate, thereby reducing the dependence on energy during the operation of the device, thereby improving the energy-saving effect of the device, and having a high promotion value.

[0032] Furthermore, when injecting material into the inner tank body 2, first connect the feed pipe 5 to the discharge end of the pump body 6, then start the pump body 6, and then extract the polyurethane raw material and inject it into the inner tank body 2 through the feed pipe 5, the spiral tube 7 and the injection pipe 8. During this process, an industrial fan can be turned on on one side to blow the inner tank body 2. When the polyurethane white material flows in the spiral tube 7, since the spiral tube 7 is made of aluminum alloy, it can quickly absorb the heat in the polyurethane white material and dissipate it to the outside. At this time, under the blowing of the industrial fan, the wind enters between the outer tank body 1 and the inner tank body 2 through the through hole 3, thereby increasing the air flow between the outer tank body 1 and the inner tank body 2, further improving the heat dissipation efficiency of the device, effectively avoiding heat accumulation and causing the temperature of the inner tank body to be too high, while reducing the cost of the tank body and the storage cost of the polyurethane white material, which has a high promotion value. Secondly, under the blowing of the industrial fan, multiple tank bodies can be injected at the same time, which is very suitable for the factory's batch production and processing of polyurethane foam sealants, and has a high promotion significance.

[0033] Furthermore, after the polyurethane white material is injected into the inner tank body 2 through the injection pipe 8, the polyurethane white material impacts the first turbine blade 9, thereby driving the rotating shaft 10 to rotate, and then driving the scraper 11 to rotate. The rotation of the scraper 11 breaks up and stirs the polyurethane white material falling from the top of the inner tank body 2, and assists in dissipating the heat of the raw materials, further improving the heat dissipation effect of the device. At the same time, the polyurethane white material falls from the top of the inner tank body 2 to the bottom, which can also further dissipate heat for the polyurethane white material, thereby greatly improving the heat dissipation effect of the polyurethane white material, and has a high promotion value.

[0034] Secondly, when discharging, the discharge pipe 4 and the feed end of the pump body 6 are connected, and the pump body 6 is used to extract the polyurethane white material in the inner tank body 2. The extracted polyurethane white material impacts the second turbine blade 15 in the discharge pipe 4, thereby driving the second turbine blade 15 and the mounting shaft 13 to rotate, and through the engagement of the two bevel gears 14, the driving shaft 10 is rotated, and then the scraper 11 is driven to rotate in the inner tank body 2. Since one end of the scraper 11 is in contact with the inner wall of the inner tank body 2, the scraper 11 can scrape off the polyurethane white material adhered to the inner wall of the inner tank body 2 during the rotation process, thereby improving the completeness of the device during discharge, reducing the residue of polyurethane white material, having a high promotion value, reducing the waste of raw materials, and having a high promotion value.

[0035] Working principle: start the pump body 6, inject the polyurethane raw material into the inner tank body 2, and turn on the industrial fan on one side to blow the tank body, so that the wind enters between the outer tank body 1 and the inner tank body 2 through the through hole 3. In addition, after the polyurethane white material is injected into the inner tank body 2 through the injection pipe 8, the polyurethane white material impacts the first turbine blade 9, and drives the scraper 11 to rotate through the rotating shaft 10. The rotation of the scraper 11 breaks up and stirs the polyurethane white material falling from the top of the inner tank body 2, and assists in dissipating the heat of the raw material. At the same time, the polyurethane white material falls from the top of the inner tank body 2 to the bottom, which can also further dissipate the heat of the polyurethane white material.

[0036] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
