Description

Technical Field

[0001] This utility model relates to the technical field of polyurethane raw material storage equipment, and in particular to a storage tank for polyurethane raw materials. Background Technology

[0002] Polyurethane raw material tanks, also known as storage tanks, are specialized containers used to store the main raw materials in the polyurethane production process. Their core function is to ensure the stability and safety of the raw materials. Existing polyurethane raw material tanks are as follows:

[0003] For example, a polyurethane raw material tank disclosed in patent publication number CN211544624U includes a sealed chamber and a tank body located inside the sealed chamber. A controller is set on the side of the sealed chamber, and a motor is fixed on the top of the sealed chamber. The motor is fixed to a hollow crossbeam through a transmission shaft. Automatic telescopic rods are set at both ends inside the crossbeam. One end of the automatic telescopic rod is fixed to a lifting rod. The lifting rod passes through a horizontal groove opened at the bottom of the crossbeam. The horizontal groove is opened along the length of the crossbeam. The other end of the lifting rod is fixed to a heating sleeve. A tank body is provided between the heating sleeves. A temperature sensor is built into the bottom of the tank body. A return pipe and a discharge pipe are connected to the bottom of the tank body. A heating layer is tightly attached to the outer wall of the bottom of the tank body.

[0004] In actual operation, the above-mentioned utility model mainly utilizes a motor to drive the crossbeam to rotate, which in turn drives the heating jacket to rotate, thereby achieving uniform heating of the raw materials and enabling storage. Although the above solution can heat the raw materials, polyurethane itself has a certain degree of adhesion. This adhesive polyurethane easily adheres to the tank. If the inner wall of the tank is not cleaned in time, the raw materials will solidify on the inner wall of the tank. If it is not cleaned repeatedly, the raw materials will solidify on the previous layer of raw materials, resulting in the accumulation of solidified raw materials. When the raw materials accumulate to a certain extent, they will occupy the storage space inside the tank, thus reducing the internal storage space of the tank. Summary of the Invention

[0005] The purpose of this invention is to provide a storage tank for polyurethane raw materials, which can store and stir the raw materials inside the tank.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a storage tank for polyurethane raw materials, comprising: a tank body and a stirring rod rotatably connected to the tank body, wherein a heating wire is fixedly connected to the inner wall of the tank body.

[0007] It also includes: scraper, support base and rotating disk;

[0008] A support ring is fixedly connected to the tank body and is located on one side of the stirring rod;

[0009] A rotating disk is rotatably connected to the support ring, and one end of the rotating disk is positioned opposite to the inner wall of the tank.

[0010] A scraper is fixedly connected to the rotating disk, and one end of the scraper is in contact with the inner wall of the tank.

[0011] Preferably, the stirring rod includes a rod body and a stirring blade. The rod body is rotatably connected to the inner wall of the tank, and the stirring blade is fixedly connected to the rod body. A driving component is provided on the support ring. The driving component is connected to the rotating disk and one of the stirring blades respectively, and is used to drive the rotating disk and the stirring blade to rotate.

[0012] Preferably, the driving component includes: a motor, a spur gear, and a rotating ring. The rotating ring is rotatably connected to a support ring, and one end of the rotating ring is fixedly connected to a stirring blade. The spur gear is rotatably connected to the support ring and is connected to the rotating ring teeth. The spur gear is also connected to the rotating disk teeth. The motor is fixedly connected to the rotating disk, and the output shaft of the motor is fixedly connected to the spur gear.

[0013] Preferably, a protective shell is bolted to the support ring, and a sealing ring is fixedly connected to the protective shell, with one end of the sealing ring in contact with the support ring.

[0014] Preferably, an air outlet seat with a built-in chamber is fixedly connected to the inner wall of the tank. The top of the air outlet seat has several air outlet holes communicating with the chamber. An air pump is fixedly connected to the tank and the air pump is connected to the chamber through an air inlet pipe.

[0015] Preferably, an air outlet pipe is fixedly connected to the air outlet, and a one-way valve is fixedly connected to the air outlet pipe.

[0016] Preferably, a one-way valve is fixedly connected to the intake pipe.

[0017] Preferably, a support rod is fixedly connected to the inner wall of the tank, and one end of the support rod is fixedly connected to a support ring.

[0029] like Figures 1 to 3 A storage tank for polyurethane raw materials includes: a tank body 1 and a stirring rod 2 rotatably connected to the tank body 1. A heating wire 27 is fixedly connected to the inner wall of the tank body 1. The stirring rod 2 is used to stir the raw materials, while the heating wire 27 is used to heat the raw materials.

[0030] The storage tank of this utility model also includes: a support ring 6, a rotating disk 7, and a scraper 8;

[0031] The support ring 6 is fixedly connected to the tank body 1 by the support rod 24 and the reinforcing rib 25. The support rod 24 is fixedly connected inside the tank body 1 and one end is fixedly connected to the support ring 6 to support the support ring 6. The reinforcing rib 25 is fixedly connected to the support ring 6 and one end of the support ring 6 is fixedly connected to the support rod 24 to increase the support effect between the support rod 24 and the support ring 6. The rotating disk 7 is driven to rotate by the drive component 11 and is connected to the support ring 6. The drive component 11 can drive the rotating disk 7 to rotate, and the rotating disk 7 can drive the scraper 8 fixedly connected to the rotating disk 7 to rotate along the circumferential direction of the inner wall of the tank body 1, so as to clean the raw materials attached to the inner wall of the tank body 1.

[0032] It is worth mentioning that the drive component 11 is mainly composed of a motor 12, a spur gear 13, and a rotating ring 14. The motor 12 is fixedly connected to the support ring 6, while the spur gear 13 is rotatably connected inside the support ring 6. The output shaft of the motor 12 is fixedly connected to the spur gear 13. The spur gear 13 is connected to the rotating ring 14 and the rotating disk 7, allowing the spur gear 13 to drive the rotating ring 14 and the rotating disk 7 to rotate during rotation. This causes the rotating disk 7 to drive the scraper 8 to rotate, cleaning the attached raw materials. The rotation of the rotating ring 14, in turn, drives the stirring rod 2 to rotate, thus enabling the stirring rod 2 to stir the raw materials. It is worth mentioning that the stirring rod 2 is mainly composed of a rod body 9 and a stirring blade 10. The rod body 9 is rotatably connected to the tank body 1, and the stirring blade 10 is fixedly connected to the rod body 9. The stirring blade 10 is fixedly connected to the rotating ring 14, which enables the rotating ring 14 to drive the stirring blade 10 to drive the rod body 9 to rotate during rotation, thereby achieving the stirring of raw materials. In order to prevent the motor 12 from being affected by the raw materials, the protective shell 15 is bolted to the support ring 6 to protect the motor 12 and reduce the direct contact between the raw materials and the motor 12. The sealing ring 16, which is fixedly connected to the protective shell 15, is attached to the support ring 6 to increase the sealing effect between the protective shell 15 and the support ring 6.

[0033] Specifically, the storage tank in this utility model also includes an air outlet seat 17, an air pump 19, an air outlet pipe 21, and a one-way valve. The air outlet seat 17 has a built-in chamber 20 and is fixedly connected to the tank body 1. The top of the air outlet seat 17 has an air outlet hole 18 that communicates with the chamber 20 for transmitting airflow. The air pump 19 is fixedly connected to the tank body 1 and communicates with the chamber 20 through the air outlet pipe 21. The airflow transmitted by the air pump 19 enters the air outlet hole 18 through the air outlet pipe 21 and is discharged into the tank body 1 through the air outlet pipe 21 that communicates with the air outlet hole 18. This achieves the effect of airflow stirring the raw materials in the tank body 1 and further improves the stirring effect of the raw materials. The one-way valve is fixedly connected to the air outlet pipe 21 to reduce the possibility of raw materials entering the chamber 20.

[0034] Specifically, a second support rod 26 is fixedly connected to the rotating disk 7, and the second support rod 26 is slidably connected to the support ring 6, thereby increasing the support effect of the rotating disk 7.

[0035] The principle of this invention is as follows: the rotation of the rotating disk 7 can drive the scraper 8 to move. Once the scraper 8 moves, it will scrape off the raw material attached to the inner wall of the tank 1, thereby reducing the adhesion of the raw material. The air pump 19 transmits airflow through the chamber 20 and enters the air outlet pipe 21 through the air outlet 18, thereby realizing the stirring of the raw material by the airflow and further improving the stirring effect of the raw material.

[0036] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
