Description

Technical Field

[0001] The utility model relates to the technical field of carbon nine aromatics processing, in particular to a high-efficiency filtering device for carbon nine aromatics processing. Background Art

[0002] At present, fine carbon nine raw materials are mostly prepared in the form of aromatic hydrocarbons. They are colorless liquids at room temperature with a certain viscosity. They are important organic chemical raw materials and are often used as gasoline additives and industrial solvents. They have high industrial application value. Fine carbon nine raw materials are semi-finished products that have undergone further deep processing, such as carbon nine petroleum resins. Before deep processing, the small amount of insoluble impurities contained in them need to be filtered and removed, otherwise they may react with the carbon nine raw materials themselves during the processing process to generate toxic and harmful gases or other compounds that affect the quality of carbon nine products.

[0003] The filtering and impurity removal device for the carbon nine aromatic raw materials generally passes the material into a filter screen or filter cartridge with a fine pore structure through the feeding equipment of the carbon nine raw materials, and performs simple physical filtration through the fluidity and permeability of the carbon nine liquid itself. However, the fine carbon nine raw materials themselves have a certain viscosity, and the viscosity of the material leads to poor fluidity, and the rate of passing through the filter cartridge or filter screen is slow. Therefore, it is necessary to design a new technical solution to solve this problem, which can greatly increase the rate at which the carbon nine aromatic raw materials pass through the filter cartridge. Utility Model Content

[0004] The purpose of the utility model is to provide a high-efficiency filtering device for processing carbon nine aromatic hydrocarbons, which solves the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-efficiency filtering device for processing carbon nine aromatics, comprising a processing tank, a processing installation box is connected and installed at the bottom of the processing tank, a discharge pipe is detachably installed at the other end of the processing tank through a flange, an electric push rod is fixedly installed at the top of the processing tank, an extrusion plate is fixedly installed at the other end of the electric push rod, and a sealing extrusion mechanism is installed on the extrusion plate;

[0006] The sealing extrusion mechanism includes a rubber sleeve fixedly installed on the outer wall of the extrusion plate, a plurality of groups of equidistantly distributed pressure sensors fixedly installed on the side wall of the rubber sleeve, an extrusion groove opened on the inner wall of the rubber sleeve, an air bag fixedly installed in the extrusion groove, and an air pump fixedly installed on the top of the extrusion plate, the air outlet end of the air pump is connected to the air bag, and four groups of pressure sensors are arranged, and the four groups of pressure sensors correspond to the side walls of the processing tank.

[0007] As an optional solution of the technical solution of the present application, a distance measuring sensor is fixedly installed on the top of the processing tank. The distance measuring sensor corresponds to the extrusion plate and can measure the distance between the extrusion plates.

[0008] As an optional solution of the technical solution of the present application, a filter element is embedded in the installation box, and the filter element corresponds to the discharge port of the processing tank, so that the carbon nine aromatic hydrocarbon raw material can be filtered.

[0009] As an optional solution of the technical solution of the present application, the side wall of the airbag is connected to an exhaust pipe, and the exhaust pipe is installed with a solenoid valve to discharge the gas inside the airbag.

[0010] As an optional solution of the technical solution of the present application, a pump is fixedly installed on the side wall of the processing tank, the inlet port of the pump is connected to a feeding pipe, the outlet port of the pump is connected to a material guide pipe, and the material guide pipe is connected to the bottom of the side wall of the processing tank, so that the nine-carbon aromatic hydrocarbon raw material can be continuously introduced into the interior of the processing tank.

[0011] As an optional solution of the technical solution of the present application, telescopic rods are fixedly installed at both ends of the top side of the processing tank, and the other ends of the two groups of telescopic rods are respectively fixedly installed on the side walls of the extrusion plate, which can limit the extrusion plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The technical solution of the present application drives the electric push rod on the top of the processing tank to push the extrusion plate to move downward along the inner cavity of the processing tank. As the extrusion plate moves downward, the air pump in the sealing extrusion mechanism is driven at the same time to inflate the airbag in the extrusion groove. The expanded airbag will continuously squeeze the outside of the rubber sleeve, and the side wall of the rubber sleeve will firmly fit the side wall of the processing tank. The sealing of the extrusion plate is ensured during the downward movement of the extrusion plate, and the carbon nine aromatic raw materials in the processing tank can be continuously squeezed toward the filter element inside the installation box, so that the carbon nine aromatic raw materials with viscosity can be efficiently discharged from the filter element, avoiding the difficulty of filtering the carbon nine aromatic raw materials from the filter element with smaller filter pores.

[0014] 2. The technical solution of the present application is connected to an exhaust pipe installed through the side wall of the airbag, and a solenoid valve is installed on the exhaust pipe. When the extrusion plate completes the extrusion of the carbon nine aromatic raw materials inside the processing tank, it will drive the electric push rod to drive the extrusion plate to move up. As the extrusion plate moves up, the solenoid valve on the exhaust pipe will open to discharge the gas inside the airbag, which can effectively reduce the friction between the rubber sleeve and the side wall of the processing tank, not only making the extrusion plate reset more quickly, but also reducing the mutual wear between the rubber sleeve and the side wall of the processing tank and the pressurization service life.

[0019] See also Figure 1-2 The utility model provides a technical solution: a high-efficiency filtering device for processing carbon nine aromatics, comprising a processing tank 1, a processing installation box 11 is connected and installed at the bottom of the processing tank 1, a discharge pipe 12 is detachably installed at the other end of the processing tank 1 through a flange, an electric push rod 14 is fixedly installed on the top of the processing tank 1, an extrusion plate 2 is fixedly installed at the other end of the electric push rod 14, and a sealing extrusion mechanism is installed on the extrusion plate 2;

[0020] The sealing extrusion mechanism includes a rubber sleeve 21 fixedly installed on the outer wall of the extrusion plate 2, a plurality of groups of equidistantly distributed pressure sensors 22 fixedly installed on the side wall of the rubber sleeve 21, an extrusion groove 23 opened on the inner wall of the rubber sleeve 21, an air bag 24 fixedly installed in the extrusion groove 23, and an air pump 25 fixedly installed on the top of the extrusion plate 2. The air outlet end of the air pump 25 is connected to the air bag 24. Four groups of pressure sensors 22 are arranged. The four groups of pressure sensors 22 correspond to the side walls of the processing tank 1. The installation box 11 is embedded with a filter element 13. The filter element 13 corresponds to the discharge port of the processing tank 1, so that the carbon nine aromatic raw material can be filtered.

[0021] In this technical solution, the electric push rod 14 on the top of the processing tank 1 is driven to push the extrusion plate 2 to move downward along the inner cavity of the processing tank 1. As the extrusion plate 2 moves downward, the air pump 25 in the sealing extrusion mechanism is driven at the same time to inflate the air bag 24 in the extrusion groove 23. The expanded air bag 24 will continuously squeeze the outer side of the rubber sleeve 21, and the side wall of the rubber sleeve 21 will be firmly attached to the side wall of the processing tank 1, so that the sealing of the extrusion plate 2 is ensured during the downward movement of the extrusion plate 2, and the carbon nine aromatic raw materials in the processing tank 1 can be continuously squeezed toward the filter element 13 in the installation box 11, so that the carbon nine aromatic raw materials with viscosity can be efficiently discharged from the filter element 13, avoiding the difficulty of filtering the carbon nine aromatic raw materials from the filter element 13 with smaller filter pores.

[0022] In some technical solutions, an exhaust pipe 26 is installed in communication with the side wall of the airbag 24 , and a solenoid valve is installed on the exhaust pipe 26 to discharge the gas inside the airbag 24 .

[0023] In this technical solution, when the extrusion plate 2 completes the extrusion of the nine-carbon aromatic raw material inside the processing tank 1, it will drive the electric push rod 14 to move the extrusion plate 2 upward. As the extrusion plate 2 moves upward, the solenoid valve on the exhaust pipe 26 will open to discharge the gas inside the airbag 24, which can effectively reduce the friction between the rubber sleeve 21 and the side wall of the processing tank 1, not only making the extrusion plate 2 reset more quickly, but also reducing the mutual wear between the rubber sleeve 21 and the side wall of the processing tank 1 and the pressurization service life.

[0024] In some technical solutions, a pump 3 is fixedly installed on the side wall of the processing tank 1, the inlet of the pump 3 is connected to a feeding pipe, the outlet of the pump 3 is connected to a material guide pipe 31, and the material guide pipe 31 is connected to the bottom of the side wall of the processing tank 1, so that the nine-carbon aromatic hydrocarbon raw material can be continuously introduced into the interior of the processing tank 1.

[0025] In this technical solution, the nine-carbon aromatic raw material is continuously introduced into the guide pipe 31 by driving the pump 3, and is continuously poured into the bottom of the processing tank 1. After the nine-carbon aromatic raw material in the processing tank 1 reaches a certain height, the solenoid valve on the guide pipe 31 is closed.

[0026] In some technical solutions, telescopic rods 32 are fixedly installed at both ends of the top side of the processing tank 1, and the other ends of the two sets of telescopic rods 32 are respectively fixedly installed on the side walls of the extrusion plate 2, so as to limit the extrusion plate 2.

[0027] In this technical solution, when the extrusion plate 2 moves up and down, the telescopic rod 32 fixedly installed on one side of the extrusion plate 2 can ensure that the extrusion plate 2 is limited and the extrusion plate 2 moves up and down in the vertical direction.

[0028] In some technical solutions, a distance sensor 33 is fixedly installed on the top of the processing tank 1. The distance sensor 33 corresponds to the extrusion plate 2 and can measure the distance of the extrusion plate 2.

[0029] In this technical solution, the height of the extrusion plate 2 can be measured by the distance sensor 33 installed on the top of the processing tank 1. When the extrusion plate 2 drops to a certain height and reaches the set value of the distance sensor 33, the signal will be transmitted to the control processor to control the electric push rod 14 to automatically reset the extrusion plate 2.

[0030] When a high-efficiency filtering device for processing carbon nine aromatics is used, it should be noted that the utility model is a high-efficiency filtering device for processing carbon nine aromatics, and each component is a universal standard part or a component known to technical personnel in this field, and its structure and principle can be known to technical personnel through technical manuals or through conventional experimental methods.

[0031] When in use, firstly, the carbon nine aromatic raw material is continuously introduced into the guide pipe 31 by driving the pump 3, and continuously poured into the processing tank 1 from the bottom. After the carbon nine aromatic raw material in the processing tank 1 reaches a certain height, the solenoid valve on the guide pipe 31 is closed, and the electric push rod 14 on the top of the processing tank 1 is driven to push the extrusion plate 2 to move down along the inner cavity of the processing tank 1. As the extrusion plate 2 moves down, the air pump 25 in the sealing extrusion mechanism is driven at the same time to inflate the air bag 24 in the extrusion groove 23. The expanded air bag 24 will continuously squeeze the outer side of the rubber sleeve 21, and the side wall of the rubber sleeve 21 will be firmly attached to the side wall of the processing tank 1, so that the extrusion plate 2 can ensure the sealing of the extrusion plate 2 during the downward movement, and the carbon nine aromatic raw material in the processing tank 1 can be continuously introduced into the installation box 1. 1, so that the carbon nine aromatic raw materials with viscosity are efficiently discharged from the filter element 13, and it is prevented that the carbon nine aromatic raw materials are difficult to filter from the filter element 13 with smaller filter holes. At the same time, an exhaust pipe 26 is installed through the side wall of the air bag 24, and an electromagnetic valve is installed on the exhaust pipe 26. When the extrusion plate 2 completes the extrusion of the carbon nine aromatic raw materials inside the processing tank 1, the electric push rod 14 will be driven to drive the extrusion plate 2 to move upward. As the extrusion plate 2 moves upward, the electromagnetic valve on the exhaust pipe 26 will be opened to discharge the gas inside the air bag 24, which can effectively reduce the friction between the rubber sleeve 21 and the side wall of the processing tank 1, not only making the extrusion plate 2 reset more quickly, but also shortening the mutual wear and pressurization service life of the rubber sleeve 21 and the side wall of the processing tank 1.
