Description

Technical Field

[0001] The present application relates to the field of chemical production and transportation technology, and in particular to a solid-liquid mixture anti-blocking and conveying system for a chemical production line. Background Art

[0002] Triphenylphosphine is the basic raw material of rhodium phosphine complex catalyst and has a wide range of uses in domestic petrochemical industry. Triphenylphosphine is also used in the fields of pharmaceutical industry, organic synthesis, analysis, etc. The preparation process of triphenylphosphine involves multiple steps, including synthesis, quenching, crystallization, etc. In these steps, a large amount of solid-liquid mixture is involved. The transportation of solid-liquid mixture is a key link in the chemical production process, and its efficiency and safety directly affect the stability of the entire production line and product quality.

[0003] During the transportation of solid-liquid mixtures, due to the viscosity and uneven particle size of the solid-liquid mixtures, after the material transportation is completed, the solid-liquid mixture is easily left in the elbows, joints, horizontal and inclined parts of the transportation pipeline. The left solid-liquid mixture will form a blockage after cooling. Utility Model Content

[0004] The utility model aims to provide a solid-liquid mixture anti-blocking conveying system for a chemical production line, which can prevent the solid-liquid mixture from being left in the elbows, joints, horizontal and inclined parts of the conveying pipeline after the solid-liquid mixture is conveyed.

[0005] This application is implemented through the following technical solutions, specifically:

[0006] A material conveying system for preventing blockage of solid-liquid mixture in a chemical production line comprises a material conveying pipeline, a first reaction tank connected to one end of the material conveying pipeline, and a second reaction tank connected to the other end of the material conveying pipeline; the characteristic is that the material conveying pipeline comprises at least one curved portion and a straight pipe portion connected to the curved portion, and the straight pipe portion is connected to a gas source device.

[0007] In this solution, an air source device is connected to the side end of the straight pipe portion connected to the curved portion in the conveying pipeline. When the curved portion is blocked by a solid-liquid mixture, the material blocked by the curved portion can be cleared by the positive-pressure gas output by the air source device. The material remaining on the inner wall of the conveying pipeline can also be cleaned in time to avoid interruption of material transportation and improve the transportation efficiency of the conveying system in long-distance transportation scenarios.

[0008] As an improvement to the solution of the present application, the exhaust port of the gas source device is connected to the side end opening of the straight pipe portion; the gas source device also includes an exhaust valve connected to the exhaust port.

[0009] In this solution, the exhaust port of the gas source equipment is connected to the side end of the straight pipe. The gas is blocked by the wall of the straight pipe and has two flow directions, upward and downward. The downward airflow can effectively solve the blockage of the solid-liquid mixture in the curved part, and the upward airflow can timely clean the residual materials on the inner wall of the straight pipe and recycle them to the first reaction tank. In addition, by setting the exhaust valve, the operator can flexibly adjust the gas flow according to actual needs, which helps to optimize the feeding effect, reduce the potential damage to the feeding pipeline caused by gas shock or pressure fluctuation, and ensure the stability of the feeding system.

[0010] As an improvement to the gas source equipment in the present application, in order to ensure the stability of the solid-liquid mixture, the gas source equipment includes at least one of a nitrogen compressor, a nitrogen storage tank and a nitrogen generator.

[0011] As an improvement of the scheme of the present application, in order to ensure the stability of the feeding system, the chemical production line solid-liquid mixture anti-blocking feeding system also includes a first valve body arranged at the connection between the first reaction tank and the feeding pipeline and a second valve body arranged at the connection between the second reaction tank and the feeding pipeline.

[0012] The beneficial effects of this application are:

The solution of the present application connects an air source device to the side end of a straight pipe portion connected to a curved portion in a conveying pipeline, so that when the curved portion is blocked by a solid-liquid mixture, the material blocked by the curved portion can be cleared by positive pressure gas output by the air source device.

[0019] The following will be combined with the attached Figure 1 The embodiments of the technical solution of the present application are described in detail. The following embodiments are only used to more clearly illustrate the technical solution of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application. In addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] In view of the problems existing in the prior art in the background technology, the embodiment of the present application provides a solid-liquid mixture anti-blocking feeding system for a chemical production line, such as Figure 1 As shown in the structural schematic diagram, the solid-liquid mixture anti-blocking conveying system of the chemical production line includes: a conveying pipeline 1, a first reaction tank 2 connected to one end of the conveying pipeline 1 and a second reaction tank 3 connected to the other end of the conveying pipeline 1; the conveying pipeline 1 includes at least one curved portion 11 and a straight pipe portion 12 connected to the curved portion 11, and the straight pipe portion 12 is connected to a gas source device 4.

[0021] Specifically, the curved portion 11 includes the curved portions, diameter-changing portions, connecting portions and low-lying areas of the feed pipeline 1 which are not smooth enough or have gaps. These areas are prone to accumulation of materials and cause blockages. In particular, the solid-liquid mixture has a certain degree of adhesion. In the process of transporting the solid-liquid mixture from the first reaction tank 2 to the second reaction tank 3, it is more likely to cause deposition in the curved portion 11 of the feed pipeline 1.

[0022] In this embodiment, the side end of the straight pipe portion 12 connected to the curved portion 11 in the conveying pipeline 1 is connected to the gas source device 4, so that when the curved portion 11 is blocked by the solid-liquid mixture, the positive pressure gas output by the gas source device 4 can clear the material blocked in the curved portion 11.

[0023] Continue to view Figure 1 In one implementation, the exhaust port 41 of the gas source device 4 is connected to the side opening of the straight pipe portion 12 ; the gas source device 4 also includes an exhaust valve 42 connected to the exhaust port 41 .

[0024] Specifically, in this embodiment, the exhaust port 41 of the gas source equipment 4 is connected to the side end of the straight pipe portion 12. The positive pressure gas is blocked by the pipe wall of the straight pipe portion 12 and has two flow directions, upward and downward. The downward airflow can effectively solve the blockage of the solid-liquid mixture in the curved portion 11, and flush the solid-liquid mixture to the second reaction tank 3. The upward airflow can promptly clean the material remaining on the inner wall of the straight pipe portion 12 and recycle it to the first reaction tank 2.

[0025] The exhaust valve 42 provided in this embodiment can facilitate the operator to flexibly adjust the gas flow rate according to actual needs, which helps to optimize the feeding effect, and can also reduce the potential damage to the feeding pipeline 1 caused by gas shock or pressure fluctuation, thereby ensuring the stability of the feeding system.

[0026] Based on the above embodiments, continue to refer to Figure 1 In one implementation, the gas source equipment 4 includes at least one of a nitrogen compressor, a nitrogen storage tank and a nitrogen generator.

[0027] Specifically, nitrogen is a gas with stable chemical properties and is not easy to react chemically with other substances. This stability allows nitrogen, when used as a gas source, to effectively prevent oxidation, corrosion and other reactions from occurring during the transportation or processing of the solid-liquid mixture, thereby contaminating the solid-liquid mixture and ensuring the stability and safety of the feeding system. The gas source device 4 in this embodiment can selectively select one of a nitrogen compressor, a nitrogen storage tank and a nitrogen generator, or integrate two or three gas source devices 4 to ensure that the gas source device 4 can provide a stable and controllable positive pressure nitrogen supply to the feeding pipeline 1, thereby effectively preventing the blockage of the solid-liquid mixture.

[0028] Optionally, gas supply points are set at multiple locations of the conveying pipeline 1, the gas source equipment 4 is connected to multiple gas supply pipes, and the gas supply pipes are connected to the gas supply points to adapt to the transportation of solid-liquid mixtures under different transportation conditions and requirements.

[0029] Based on the above embodiments, continue to refer to Figure 1 In one implementation, the solid-liquid mixture anti-blocking feeding system for a chemical production line is characterized in that it also includes: a first valve body 51 arranged at the connection between the first reaction tank 2 and the feeding pipeline 1 and a second valve body 52 arranged at the connection between the second reaction tank 3 and the feeding pipeline 1.

[0030] Specifically, the first valve body 51 is mainly used to control the flow rate and timing of the solid-liquid mixture entering the feed pipeline 1 from the first reaction tank 2. The second valve body 52 is located at the other end of the feed pipeline 1 and is connected to the second reaction tank 3 to control the flow rate and speed of the solid-liquid mixture entering the second reaction tank 3 from the feed pipeline 1.

[0031] Illustratively, when the solid-liquid mixture in the first reaction tank 2 is emptied, the first valve body 51 can be opened to allow the gas source device 4 to deliver positive pressure gas to blow the solid-liquid mixture adhered to the inner wall of the straight pipe portion 12 of the feed pipeline 1 to the first reaction tank 2 for recovery, thereby improving the material recovery efficiency.

[0032] This embodiment enhances the safety and stability of the material conveying system by providing the first valve body 51 and the second valve body 52, and effectively prevents leakage and blockage of the solid-liquid mixture during the conveying process. In practical applications, operators can flexibly adjust the opening degree and timing of the first valve body 51 and the second valve body 52 according to production needs and process requirements to ensure the smooth progress of the production process and the stability and reliability of product quality.

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
