Description

Technical Field

[0001] The utility model belongs to the technical field of chemical production, and particularly relates to an aluminum chloride sublimation collection device. Background Art

[0002] Aluminum chloride is an inorganic compound that usually exists in its anhydrous form and appears as a colorless or light yellow solid with a high density. Due to its relatively low melting point and boiling point, it is easy to sublimate. Under heating conditions, it will directly change from solid to gas without going through a liquid stage. Aluminum chloride is widely used in many fields, such as a catalyst, an initiator for resin synthesis, and a dehydrating agent in organic synthesis. Aluminum chloride sublimation collection device is a device designed to capture and cool aluminum chloride gas produced by sublimation so that it can be re-condensed into a solid. Such devices usually include a confined space in which the temperature and pressure conditions can be controlled so that the aluminum chloride sublimates and contacts the condensation surface through a specific path, thereby converting it into a solid form for recovery. The existing aluminum chloride sublimation collection device cannot filter the impurities in the gas after aluminum chloride sublimation, so that the collected aluminum chloride contains impurities.

[0003] For example, the utility model with announcement number CN211595055U discloses an environmentally friendly aluminum chloride sublimation collection device, a collecting hood and a flue gas duct connected to the gas exhaust port on the top of the collecting hood. The collecting hood is a trapezoidal platform structure, and the gas exhaust port is arranged on the top surface of the trapezoidal platform of the collecting hood. The lower side of the trapezoidal platform of the collecting hood is a collecting port and covers the chlorination reaction furnace. In this patent scheme, the aluminum chloride is collected through the collecting hood, and it cannot filter the aluminum chloride gas entering the sublimation device. The aluminum chloride gas may carry solid particles, impurities or other harmful substances, which may enter the interior of the device, not only resulting in impurities in the collected aluminum chloride, but also affecting the normal operation of the device and product quality. Utility Model Content

[0004] In view of this, the utility model aims at the deficiencies of the prior art and provides an aluminum chloride sublimation collection device. The filter plate can effectively remove solid particles and impurities in the aluminum chloride gas to ensure the purity and quality of the product, which not only ensures the cleanliness and pollution-free inside the device, but also ensures the normal operation of the device.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is an aluminum chloride sublimation collection device, including a collection box, an air outlet pipe is arranged in the air outlet hole opened at the upper end of the collection box, a cavity box is arranged in the installation port opened on the right side of the collection box, an air inlet pipe is arranged in the air inlet hole opened on the right side of the cavity box, a glass observation window is arranged on the front side of the collection box, a cavity plate is arranged inside the left side of the collection box, connecting pipes are arranged on the upper and lower sides of the cavity plate, the two connecting pipes are connected with the interior of a cavity plate, a filtering mechanism is arranged inside the cavity box, a scraping mechanism is arranged on the rear side of the collection box, the filtering mechanism includes a filter plate slidably arranged inside the cavity box, a handle is arranged on the front side of the filter plate, a quick assembly and disassembly mechanism is arranged on the front side of the cavity box, the quick assembly and disassembly mechanism includes two rotating columns rotatably arranged on the front side of the cavity box, a baffle is fixedly sleeved on the outer arc surface of the two rotating columns, the two baffles are installed in cooperation with a filter plate, a limiting disk is arranged at the front end of the two rotating columns, springs are respectively arranged between the limiting disk and the baffle, and the two springs are sleeved on the corresponding outer arc surface of the rotating column.

[0006] As a further improvement of the utility model, two mounting plates corresponding to left and right positions are arranged at the lower end of the collection box, and two mounting holes are provided inside the two mounting plates.

[0007] As a further improvement of the utility model, the scraping mechanism includes a slide rail arranged on the rear side of the collection box, a scraper installed in cooperation with the cavity plate is slidably arranged inside the slide rail, a screw rod is rotatably arranged inside the slide rail, the rear end of the scraper rod is threadedly connected to the screw rod, a drawer is slidably connected to the lower end of the collection box, a handle is arranged at the front end of the drawer, and an electric drive unit for driving the screw rod to rotate is arranged at the upper end of the slide rail, the electric drive unit includes a motor arranged at the upper end of the slide rail, and the output shaft of the motor is connected to the upper end of the screw rod through a coupling.

[0008] As a further improvement of the utility model, a control panel is arranged on the front side of the collection box, and the motor is electrically connected to the control panel.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] Firstly, by connecting the two connecting pipes to an external circulating coolant mechanism, the temperature of the outer surface of the cavity plate is reduced, and then the air inlet pipe is connected to the external aluminum chloride gas. The aluminum chloride gas passes through the filter plate to filter the solid particles and impurities on the inner wall and enters the inner wall of the collecting box. The aluminum chloride gas is condensed into a solid state by the cavity plate and adheres to the cavity plate. The remaining gas is discharged through the outlet pipe. The filter plate can effectively remove the solid particles and impurities in the aluminum chloride gas, ensuring the purity and quality of the product, not only ensuring the cleanliness and pollution-free inside the device, but also ensuring the normal operation of the device.

[0011] Secondly, by controlling the motor to run, the output shaft rotates to drive the screw to rotate and then drives the scraper to move downward to scrape the solid aluminum chloride adhering to the cavity plate and drop it into the inside of the drawer. The personnel can pull out the drawer through handle 2, which is convenient for the personnel to carry out subsequent processing of the solid aluminum chloride inside, making it more convenient for the personnel to use.

[0012] Third, pull and rotate the baffle to make it leave the surface of the filter plate, then pull out the filter plate through handle 1, then slide the new filter plate into the interior of the cavity box, pull and rotate the baffle to make it correspond to the surface of the filter plate, then release the baffle, and the spring will rebound quickly to drive the baffle to move to the surface of the filter plate, thereby realizing rapid replacement of the filter plate, saving installation time and increasing production efficiency.

[0013] Fourthly, the collecting device can be quickly installed through the mounting holes on the mounting plate, which can make the operation of the collecting device more stable. BRIEF DESCRIPTION OF THE DRAWINGS
