Description

Technical Field

[0001] This utility model relates to the field of storage tank technology, specifically a storage tank for the production of polyurethane resin. Background Technology

[0002] Storage tanks used in polyurethane resin production are critical equipment for ensuring product quality and production continuity, playing a vital role in the polyurethane resin production process. The selection of materials for these storage tanks is very particular, typically using high-quality stainless steel or other materials with excellent corrosion resistance. This is because polyurethane resin and its raw materials are highly chemically corrosive; if the storage tank material is inadequate, corrosion can easily occur, affecting the resin quality and the lifespan of the storage tank. In terms of capacity design, storage tanks can be customized according to different production scales. Large-capacity storage tanks can meet the needs of large-scale production, reducing the frequency of feeding and improving production efficiency; while small-capacity storage tanks are suitable for small-scale production or experimental scenarios, offering greater flexibility. Furthermore, the outer surface of the storage tanks usually undergoes special treatment to enhance their oxidation resistance and wear resistance. The tanks are also equipped with necessary instruments and interfaces, facilitating operators to monitor the resin storage status and perform related operations, ensuring a stable and orderly production process.

[0003] Storage tanks used in polyurethane resin production often have poor sealing between the lid and the tank body during use, which can easily allow impurities such as moisture and oxygen in the air to enter the tank and react with the resin, thereby changing the resin's properties. Utility Model Content

[0004] The purpose of this utility model is to provide a storage tank for polyurethane resin production, which solves the problem that the sealing effect between the lid and the tank body is poor when the storage tank is used for polyurethane resin production, which easily leads to impurities such as moisture and oxygen in the air entering the tank and reacting with the resin, thereby changing the performance of the resin.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a storage tank for polyurethane resin production, comprising a tank body, a lid threadedly connected to the upper end of the tank body, a gasket fixedly connected inside the tank body, a connecting seat slidably connected inside the lid, the connecting seat slidably connected to the tank body, a sealing gasket contacting the lower end of the connecting seat, a positioning block fixedly connected to the upper end of the sealing gasket, the positioning block slidably connected to the connecting seat, a sliding rod fixedly connected to the upper inner side of the lid, a slider fixedly connected to the outer side of the sliding rod, the sliding rod slidably connected to the connecting seat, the slider slidably connected to the connecting seat, a fixing frame fixedly connected inside the connecting seat, a threaded rod rotatably connected inside the lid, the threaded rod being threadedly connected to the connecting seat, and a pressure relief mechanism provided on the tank body.

[0006] Preferably, the sealing gasket is in contact with the tank body and the gasket ring. The design of the sealing gasket can increase the sealing performance between the lid and the tank body.

[0007] Preferably, a locking block is fixedly connected to the upper end of the sealing gasket, and the locking block engages with the connecting seat. Through the design of the locking block, the sealing gasket can be disassembled and replaced.

[0008] Preferably, the fixing frame is in contact with the slide rod, and the fixing frame is slidably connected to the slider. The design of the fixing frame can limit the position of the connecting seat.

[0009] Preferably, a retaining ring is fixedly connected to the outer side of the threaded rod, and the retaining ring contacts the inner wall of the cover. The retaining ring is designed to limit the movement of the threaded rod.

[0010] Preferably, a knob is fixedly connected to the upper end of the threaded rod, and the knob contacts the cover. The design of the knob allows the threaded rod to be rotated easily.

[0011] Preferably, the pressure relief mechanism includes a sleeve, which is fixedly connected to the inside of the tank. A connecting rod is slidably connected to the inside of the sleeve. A damping block is fixedly connected to the right end of the connecting rod. The damping block is slidably connected to the sleeve. A fixing ring is fixedly connected to the inside of the sleeve and contacts the damping block. A spring is provided on the outside of the connecting rod. One end of the spring contacts the sleeve, and the other end of the spring contacts the connecting rod. An air hole is provided inside the sleeve. Through the design of the pressure relief mechanism, the tank can be automatically depressurized.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by incorporating components such as a gasket ring, a sealing gasket, and a threaded rod, allows the sealing gasket to be brought into contact with the gasket ring by rotating the threaded rod after the lid is installed with the tank body. This effectively increases the sealing performance between the lid and the tank body, solving the problem of poor sealing between the lid and the tank body in storage tanks used for polyurethane resin production. This problem allows impurities such as moisture and oxygen in the air to enter the tank, react with the resin, and thus change the resin's properties.

[0014] 2. This utility model, by incorporating components such as a sleeve, damping block, and air hole, allows the tank to release pressure effectively when the internal pressure is too high. By using air pressure to move the damping block to the left side of the air hole, the damping block no longer blocks the air hole, allowing the tank to release pressure through the air hole.

A positioning block 33 is fixedly connected to the upper end of the sealing gasket 32, and the positioning block 33 slidably connected to the connecting seat 31.

[0023] Please see Figure 2-5A locking block 34 is fixedly connected to the upper end of the sealing gasket 32. The locking block 34 engages with the connecting seat 31. The design of the locking block 34 allows the sealing gasket 32 ​​to be disassembled and replaced. A sliding rod 4 is fixedly connected to the upper inner side of the cover 2. A slider 41 is fixedly connected to the outer side of the sliding rod 4. The sliding rod 4 is slidably connected to the connecting seat 31, and the slider 41 is also slidably connected to the connecting seat 31. A fixing frame 42 is fixedly connected inside the connecting seat 31. The fixing frame 42 contacts the sliding rod 4 and is slidably connected to the slider 41. The design of 2 can limit the connection seat 31. The inside of the cover 2 is rotatably connected to a threaded rod 43, which is connected to the connection seat 31 by a thread. A retaining ring 44 is fixedly connected to the outside of the threaded rod 43, and the retaining ring 44 contacts the inner wall of the cover 2. The design of the retaining ring 44 can limit the threaded rod 43. A knob 45 is fixedly connected to the upper end of the threaded rod 43, and the knob 45 contacts the cover 2. The design of the knob 45 can easily rotate the threaded rod 43. A pressure relief mechanism 5 is provided on the tank body 1.

[0024] Please see Figure 2-5 The pressure relief mechanism 5 includes a sleeve 51. The sleeve 51 is fixedly connected inside the tank body 1. A connecting rod 52 is slidably connected inside the sleeve 51. A damping block 53 is fixedly connected to the right end of the connecting rod 52.

[0025] The specific implementation process of this utility model is as follows: When in use, by rotating the knob 45, the knob 45 drives the threaded rod 43 to rotate, causing the threaded rod 43 to move with the connecting seat 31, thereby causing the connecting seat 31 to move on the slide rod 4, causing the connecting seat 31 to drive the sealing gasket 32 ​​to fit with the gasket ring 3, thereby effectively increasing the sealing between the tank body 1 and the lid 2.

[0026] When the pressure inside the tank 1 is too high, the air pressure enters the sleeve 51 through the fixed ring 54, which drives the damping block 53 to move. The damping block 53 drives the connecting rod 52 to squeeze the spring 55, so that the damping block 53 no longer blocks the air hole 56, and the air pressure can be discharged through the air hole 56, which can effectively relieve the pressure in the tank 1.
