Description

Technical Field

[0001] The utility model relates to the field of chemical reagent storage equipment, in particular to an easy-to-clean, dehydrated and dried stabilizer storage tank. Background Art

[0002] In the processing of plastic products such as PVC films, heat stabilizers need to be added. Commonly used heat stabilizers are lead salt stabilizers, barium cadmium stabilizers and calcium zinc stabilizers. Among them, lead salt stabilizers have the characteristics of good thermal stability, excellent electrical properties and low cost, and are widely used.

[0003] Lead salt stabilizers are in liquid form and are stored in tanks. Due to gravity, heavy metal ions will precipitate. After a certain period of time, the components of the stabilizer will be stratified, resulting in uneven concentrations of the components of the stabilizer, which will lead to unstable product quality during use. In response to this situation, manual stirring is usually used to improve it, but it is inefficient and labor-intensive.

[0004] The applicant applied for a Chinese utility model patent CN2018210014803 on June 27, 2018, and the invention name is "A liquid stabilizer storage tank for PVC film production". The air is blown into the tank body by a jet stirring device with a specific structure, which generates agitation to fully transfer the components of the stabilizer, thereby forming a homogeneous and stable mixture, and ultimately improving the stability of the quality of the enterprise's processed products. However, in actual application, we found that the liquid stabilizer storage tank for PVC film production still has some shortcomings: the mixing uniformity of the stabilizer is still not high, the air contains moisture, which leads to the reduction of the stabilizer performance or even failure, and the inner wall of the tank is not easy to clean.

[0005] Therefore, in response to the above technical problems, we designed an easy-to-clean, dehydrated and dried stabilizer storage tank. Utility Model Content

[0009] The rotary gas transmission component includes a hollow shaft stepper motor, which is vertically arranged directly below the tank body. The upper end of the hollow motor shaft of the hollow shaft stepper motor is coaxially fixedly connected to the gas pipe shaft through a sealing flange. The gas pipe shaft passes through and is rotatably connected to the bottom center of the tank body. A shaft sealing structure that cooperates with the gas pipe shaft seal is installed at the bottom center of the tank body. The gas pipe shaft and the shaft sealing structure are rotatably and slidably connected up and down. The upper end of the gas pipe shaft is fixedly connected to the bottom center air inlet of the dispersion disk. The lower end of the hollow motor shaft of the hollow shaft stepper motor is connected to the gas outlet end of the second gas pipeline through a rotary joint. The power supply device is electrically connected to the hollow shaft stepper motor, and the control device is signal-connected to the hollow shaft stepper motor.

[0010] The lifting device includes a screw stepper motor and a light bar. The screw stepper motor is vertically arranged and fixedly installed on the ground below the tank body. A moving block is fixedly installed on one side of the body of the hollow shaft stepper motor. The screw of the screw stepper motor vertically penetrates the moving block and is threadedly connected to the moving block. The upper end of the screw of the screw stepper motor is rotatably installed on the bottom of the tank body. The light bar is vertically arranged on one side of the screw stepper motor. The two ends of the light bar are respectively fixedly connected to the bottom of the tank body and the ground.

The power supply device is electrically connected to the screw stepper motor, and the control device is signal connected to the screw stepper motor.

[0012] A liquid level gauge is connected to the side of the tank body, a pressure switch is arranged on the tank body, and the pressure switch is connected to the control device signal.

[0013] The utility model has substantial features and progress compared with the prior art. Specifically, the working principle of the utility model is as follows: when the tank material is stirred and mixed with gas, the two-position three-way solenoid valve is energized, the first passage and the second passage of the two-position three-way solenoid valve are connected, the third passage of the two-position three-way solenoid valve is disconnected, and the automatic control valve is initially in an open state, then the air compressor, the air purification device, the electric heating box and the lower end of the hollow motor shaft of the hollow shaft stepper motor are connected through the second gas transmission pipeline, and the control device controls the air compressor, the air purification device, the hollow shaft stepper motor and the electric heating box to work at the same time, the air compressor provides gas of a certain pressure, and the gas passes through the air purification device After purification, the gas enters the box, and the electric heating wire is energized to heat the gas entering the box. Different heating temperatures are set according to requirements. The gas with a certain temperature enters the dispersion disk through the hollow motor shaft of the hollow shaft stepper motor and the gas pipe shaft. At the same time, the hollow shaft stepper motor drives the dispersion disk to rotate through the gas pipe shaft, and the gas with a certain temperature is ejected through each spiral nozzle to achieve stirring and mixing of the liquid stabilizer in the tank. Due to the rotation of the dispersion disk, the gas also rotates with the dispersion disk when it is ejected, which can increase the gas stirring intensity and uniformity, so that the liquid stabilizer is stirred more uniformly, and the gas with a certain temperature can keep the temperature of the liquid stabilizer warm. Among them, the control device controls the automatic control valve switch at a fixed time or controls the automatic control valve switch according to the input signal of the pressure switch, so that the gas stirring and mixing operation is intermittent, which can save energy and ensure the stability effect. The electric heating box dehydrates and dries the air, so that the air used to stir the stabilizer does not contain moisture, and avoids the stabilizer from being integrated into the water vapor contained in the air and reducing its performance or even failing.

[0014] When the liquid stabilizer in the tank is used up and the inner wall of the tank needs to be cleaned, the air compressor and the air purification device stop working, and the two-position three-way solenoid valve is controlled to be powered off, the first passage and the third passage of the two-position three-way solenoid valve are connected, and the second passage of the two-position three-way solenoid valve is disconnected, then the air compressor, the air purification device, the electric heating box and the lower end of the hollow motor shaft of the hollow shaft stepper motor are disconnected, and the water inlet pipe is connected to the lower end of the hollow motor shaft of the hollow shaft stepper motor through the second air supply pipeline, so that high-pressure water passes through the water inlet pipe and the second air supply pipeline. The hollow motor shaft of the line and hollow shaft stepper motor and the air pipe shaft enter the dispersion plate, and the high-pressure water is sprayed out through each spiral nozzle to spray and clean the inner wall of the tank body. At the same time, the screw stepper motor is controlled to work, and the screw of the screw stepper motor drives the hollow shaft stepper motor to move up and down through the moving block. The hollow shaft stepper motor drives the dispersion plate to move up and down inside the tank body through the air pipe shaft. The dispersion plate rotates and reciprocates up and down at the same time, so that the water flow sprayed from each spiral nozzle can evenly spray the inner wall of the tank body for thorough cleaning.

[0015] Among them, the tank body, dispersion plate, air compressor, air purification device, automatic control valve, control device, liquid level gauge and pressure switch have been recorded in detail in Chinese utility model patent CN2016204309625, and the specific structure and working principle will not be repeated here.
