Description

Technical Field

[0001] The utility model belongs to the technical field of resin recovery equipment, and particularly relates to a resin particle treatment system. Background Art

[0002] In chemical production, it is a common production means to use resin to adsorb and separate substances. According to the relevant regulations of the current labor hygiene regulations and environmental protection law in China, it must be treated to meet the requirements of labor hygiene and environmental protection emissions. Selecting the correct automatic control treatment method for resin particles can avoid and reduce the impact on the physical and mental health of operating workers and the emissions to the surrounding atmospheric environment.

[0003] The prior art usually discharges the substances in the adsorption tower and then treats them in an open space to recover the resin. However, people who live in waste resin particles for a long time are prone to pneumoconiosis, and in severe cases, poisoning or even death may occur; the waste gas generated by some resin particles may even explode when encountering an open flame, causing major accidents. When combustible dust is dispersed in the air to a certain concentration and encounters a fire source with sufficient heat and temperature, it will oxidize and burn, releasing a large amount of heat, causing a sudden increase in gas pressure and an uncontrollable expansion effect, resulting in an explosion. If the space is enclosed, a chain explosion will occur.

[0004] Therefore, it is necessary to design a closed resin particle treatment system to avoid safety accidents or health hazards during the process of operators recovering and treating waste resin particles. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a resin particle treatment system to solve the problem that the prior art is prone to affecting the health of operators or causing safety accidents during the recovery and treatment of resin particles. The resin particle treatment system does not need to expose the resin particles to the outside during the process of treating resin particles, and can fully separate the liquid from the resin particles and recover the resin particles.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A resin particle treatment system includes an adsorption tower, a resin tank, a gas-water separator, and a compressed air unit for providing compressed air. The air outlet end of the compressed air unit is connected to a first pipeline, the other end of the first pipeline is connected to the bottom of the adsorption tower, a second pipeline communicating with the resin tank is arranged at the lower part of the adsorption tower, a third pipeline is arranged at the top of the adsorption tower, the end of the third pipeline is connected with a first branch pipe and a second branch pipe, the first branch pipe is communicated with an external waste liquid tank, and the second branch pipe is communicated with the air inlet end of the gas-water separator.

[0008] In the resin particle treatment system of the present utility model, the liquid outlet end of the gas-water separator is communicated with an externally provided mother liquid tank.

[0009] In the resin particle treatment system of the present utility model, the compressed air unit includes an air compressor, a gas storage tank, a first filter, a refrigerated dryer, and a second filter that are connected in sequence. The gas outlet end of the second filter is communicated with a first pipeline.

[0010] In the resin particle treatment system of the present utility model, the number of the second filters is two.

[0011] In the resin particle treatment system of the present utility model, the compressed air unit further includes a compressed air tank and an instrument air storage tank. The gas outlet end of the second filter is respectively communicated with the compressed air tank and the instrument air storage tank through a three-way pipe. The gas outlet end of the compressed air tank is communicated with the first pipeline.

[0012] In the resin particle treatment system of the present utility model, a sieve plate is arranged in the adsorption tower. One end of the second pipeline communicated with the adsorption tower is on one side of the sieve plate so that the resin particles on the sieve plate are transported to the resin tank through the second pipeline.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Embodiment

[0020] Please refer to Figure 1-2 , the present utility model provides a technical solution: a resin particle treatment system, including an adsorption tower 1, a resin tank 2, a gas-water separator 3 and a compressed air unit for providing compressed air. The air outlet end of the compressed air unit is connected to a first pipeline 4, the other end of the first pipeline 4 is connected to the bottom of the adsorption tower 1, a second pipeline 5 communicating with the resin tank 2 is arranged at the lower part of the adsorption tower 1, a third pipeline 6 is arranged at the top of the adsorption tower 1, the end of the third pipeline 6 is connected with a first branch pipe 7 and a second branch pipe 8, the first branch pipe 7 is communicated with an external waste liquid tank, and the second branch pipe 8 is communicated with the air inlet end of the gas-water separator 3.

[0021] In practical applications, before recovering the resin particles in the adsorption tower 1, first start the compressed air unit to send air into the adsorption tower 1 through the first pipeline 4 by using compressed air. The gas sweeps the resin particles and takes away the waste liquid attached to the surface of the resin particles and enters the third pipeline 6. The gas with waste liquid is sent to the gas-water separator 3 through the second branch pipe for gas-liquid separation, and then the resin particles are transported to the resin tank 2 through the second pipeline 5 by using compressed air for resin particle recovery.

[0022] In this process, the resin particles and the waste liquid are separated by compressed air, and the resin particles are transported by compressed air and the second pipeline 5. The transportation process is fully enclosed, avoiding the human health problems caused by manual recovery of resin particles and reducing the occurrence of safety accidents.

[0023] In order to better control the flow direction of the compressed air driving the waste liquid or resin particles, valves are arranged on the first pipeline 4, the second pipeline 5 and the second branch pipe 8; a safety valve is arranged on the first branch pipe 7. The purpose is to avoid potential safety hazards caused by excessive flow rate of the compressed air resulting in excessive pressure in the adsorption tower 1. Through the arrangement of the safety valve and the first branch pipe 7, when the pressure in the adsorption tower 1 is too high, the pressure can be relieved through the first branch pipe 7, and the first branch pipe 7 is communicated with the waste liquid tank, avoiding the dust or waste liquid carried by the compressed air directly entering the outside world and polluting the environment during the pressure relief process.

[0024] Furthermore, in this embodiment, the liquid outlet end of the gas-water separator 3 is communicated with an external mother liquid tank.

[0025] When the gas with waste liquid is sent to the gas-liquid separator 3 for gas-liquid separation, the separated waste liquid will enter the mother liquid tank from the liquid outlet end of the gas-liquid separator 3, so as to fully recover the waste liquid for treatment and avoid polluting the environment.

[0026] As a preferred solution of this embodiment, the compressed air unit includes an air compressor 9, a gas storage tank 10, a first filter 11, a refrigerant dryer 12, and a second filter 13 connected in sequence.

[0027] In order to avoid incomplete separation of resin particles and waste liquid caused by water vapor in the compressed air or too much water vapor adhering to the surface of the recovered resin particles, in this embodiment, the water vapor in the compressed air is filtered through the settings of the first filter 11, the refrigerant dryer 12, and the second filter 13.

[0028] More preferably, the number of the second filters 13 is two, and by setting two second filters 13, the water vapor in the compressed air can be fully filtered.

[0029] Based on the fact that both the first filter 11 and the second filter 13 are used for filtering water vapor, preferably, both the first filter 11 and the second filter 13 are precision filters.

[0030] Preferably, in order to make full use of the compressed air, the compressed air unit further includes a compressed air tank 14 and an instrument air storage tank 15. The air outlet end of the second filter 13 is connected to the compressed air tank 14 and the instrument air storage tank 15 respectively through two pipelines, and the air outlet end of the compressed air tank 14 is connected to the first pipeline 4.

[0031] In practical applications, the compressed air is filtered through the first filter 11, the refrigerant dryer 12, and the second filter 13 and then enters the compressed air tank 14 and the instrument air storage tank 15 for standby respectively. The air outlet end of the compressed air tank 14 is connected to the first pipeline 4, while the air outlet end of the instrument air storage tank 15 is connected to the gas-using instrument of the production line.

[0032] In the technical solution of the present invention, the lowest position of the resin particles being on the same horizontal plane as the second pipeline 5 is the best resin particle recovery position. However, if the lowest position of the resin particles is lower than the second pipeline 5, it does not affect the resin particle recovery process, but only may cause some resin particles to remain in the adsorption tower 1, affecting the resin particle recovery rate.

[0033] Therefore, as a preferred technical solution, a sieve plate is provided in the adsorption tower 1, and one end of the second pipeline 5 connected to the adsorption tower 1 is on one side of the sieve plate so that the resin particles on the sieve plate are transported to the resin tank 2 through the second pipeline 5.

[0034] In the above preferred technical solution, the lowest position of the resin particles is at the same horizontal level as the second pipeline 5 through the setting of the sieve plate, and the resin particles can be fully sent to the second pipeline 5 under the pressure of compressed air. Through the transportation of the second pipeline 5, the resin particles are fully transported into the resin tank 2.

[0035] Further preferably, an exhaust port is provided at the top of the resin tank 2 to discharge the compressed air and avoid excessive pressure in the tank.

[0036] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
