Description

Technical Field

[0001] The utility model relates to the field of curing agent conveying devices, in particular to curing agent conveying equipment with reduced blockage. Background Art

[0002] Curing agent, also known as hardener, curing agent or curing agent, is a kind of substance or mixture that promotes or controls the curing reaction. It is mainly used to promote the curing process of thermosetting resins, coatings, glues and other materials.

[0003] The curing agent conveying device is a device used to convey the curing agent from the storage container to the location where it is needed. However, the curing agent conveying device has the risk of clogging during long-term use: the curing agent itself has the characteristics of viscosity, easy crystallization or easy precipitation. During the transmission process, these characteristics may cause the curing agent to adhere to, accumulate or form a blockage in the curing agent conveying device. In addition, the curing agent may contain impurities, particles or incompletely dissolved solid components, which may also easily cause the curing agent conveying device to become blocked. Therefore, a curing agent conveying device that reduces blockage is needed to solve the problem of easy blockage of the curing agent conveying device. Utility Model Content

[0004] The purpose of the invention of the utility model is to provide a curing agent conveying device with reduced clogging in view of the problem that the curing agent conveying device is prone to clogging. The curing agent is filtered by setting a screen component, and the liquidized and solidified curing agent is heated by a first heating plate, a second heating plate and a third heating plate. Then, a motor and a reducer are used to drive a spiral rod to forcibly convey the curing agent, so as to solve the problem that the curing agent conveying device is prone to clogging.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a curing agent delivery equipment with reduced blockage, comprising a delivery pipe, a dredging component is arranged in the delivery pipe, the dredging component comprises a spiral rod, one end of the spiral rod is connected to an external driving member, a reducer is arranged between the driving member and the spiral rod, a first heating plate is arranged at the connection between the spiral rod and the delivery pipe, a second heating plate is arranged on the inner wall of the delivery pipe, a screen assembly is arranged in the delivery pipe, the screen assembly comprises a screen support rod, a screen is arranged on the screen support rod, a third heating plate for heating the screen is also arranged on the screen support rod, and one end of the screen support rod is connected to an external telescopic mechanism.

[0006] When the curing agent is transported through the pipeline, the curing agent enters the curing agent conveying device from the feed port. First, the curing agent passes through the screen assembly, and the screen filters the curing agent to prevent impurities and particulate matter in the curing agent from entering the next process. The third heating plate can heat the screen and the curing agent, so that the curing agent will not block the screen due to solidification. The heated curing agent is not easy to solidify, and it can also provide convenience for subsequent transportation. The screen support rod plays the role of supporting the screen and the third heating plate. The external driving part drives the spiral rod to rotate through the reducer to send the curing agent out of the discharge port, which has a forced curing effect on the curing agent. The conveying function can prevent the curing agent from clogging the conveying device. The first heating plate can heat the connection between the spiral rod and the conveying pipe to prevent the curing agent from solidifying at the connection, reduce the rotational resistance of the spiral belt, and heat the curing agent in the conveying pipe to prevent the curing agent from solidifying. The second heating plate can heat the curing agent in the conveying pipe to prevent the curing agent from solidifying, which is convenient for the curing agent to be transported. When the screen assembly is blocked, the operator can more conveniently take out the screen assembly for cleaning through the telescopic assembly, which avoids the screen assembly being in a blocked state for a long time and affecting the overall filtering effect.

[0007] As a preferred solution of the utility model, the conveying pipe is provided with a sealing cover for taking and placing the screen, the telescopic mechanism includes a shell, the shell is bolted to the conveying pipe, a lifting plate for lifting the screen support rod is provided in the shell, and a spring is provided between the lifting plate and the bottom end of the shell. The sealing cover plays the role of sealing the screen assembly, and the bolt connection can conveniently remove the telescopic mechanism for inspection and maintenance, and the lifting plate is used to support and lift the screen support rod. When the screen assembly is installed in the conveying pipe, the screen support rod will press the lifting plate, and the spring is in a compressed state. When the screen assembly needs to be inspected and maintained, after opening the sealing cover, the compressed spring will lift the lifting plate due to the elastic force, and the lifting plate will lift the screen assembly again, which is convenient to take out, saves manpower, and is convenient for inspection and maintenance of the screen assembly. At this time, the lifting plate is close to the conveying pipe under the action of the elastic force, and can also play a sealing role to prevent the curing agent from entering the shell.

[0008] As a preferred solution of the utility model, the screen support rod also includes a sealing plate. When the screen assembly is installed, the sealing plate can block the gap between the screen support rod and the conveying pipe to prevent the curing agent from entering the telescopic assembly and causing failure of the telescopic assembly.

[0009] As a preferred solution of the utility model, the screen is made of heat-conducting metal material, which is conducive to the third heating plate heating the screen and then heating the curing agent. The metal material can also improve the strength and durability of the screen.

[0010] As a preferred solution of the utility model, the plate surface of the third heating plate is of hollow design, which ensures the heating effect on the screen and provides a conveying space for the conveying of the curing agent.

[0011] As a preferred solution of the utility model, the driving member is a motor, a support frame for supporting the motor is provided on the conveying pipe, and a cushion is provided between the support frame and the motor. The support frame supports the motor, and the cushion can reduce noise and vibration of the motor.

[0012] As a preferred solution of the utility model, the delivery pipe is provided with a pressure sensor for checking the pressure at the feed inlet position and determining whether the screen assembly is seriously blocked.
