Description

Technical Field

[0001] This utility model relates to the field of bis(trihydroxy) production technology, specifically a precision dust collector for bis(trihydroxy) production. Background Technology

[0002] Di(trimethylolpropane) is a white, flaky material with a melting point between 108°C and 111°C. It is commonly used to make acrylic monomers, resins, lubricants, and other similar materials. Di(trimethylolpropane) tetraacrylate, due to its high crosslinking properties, is a suitable choice for preparing coatings, and its derivatives are numerous.

[0003] The production of this type of bis(trimethylolpropane) raw material often involves multiple processes, including dissolution, filtration, batching, decolorization, crystallization, concentration, condensation, recovery, slicing, and packaging. During these processes, dust and debris are inevitably generated, requiring the use of dust collectors for dust removal. However, such machines are typically only installed in one of the processes for dust extraction and cleaning, limiting their coverage and efficiency per cycle. Bis(trimethylolpropane) has high economic value, and without thorough purification and recovery, its powder will be emitted into the atmosphere with the exhaust gas, causing unnecessary environmental pollution.

[0004] Building upon existing preliminary production processes for separation and exhaust gas purification, more advanced exhaust gas purification is necessary. Therefore, a novel precision dust collector for the production of bis(trihydroxy) compounds is proposed to address these issues. Utility Model Content

[0005] The purpose of this invention is to provide a precision dust collector for the production of bis(trihydroxy) compounds, in order to solve the problem of limited dust removal efficiency mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a precision dust collector for the production of bis(trihydroxy) compounds, comprising a shell and a limiting plate. The limiting plate is fixed between the two sides of the upper part of the shell, and four sets of vertical grooves are arranged longitudinally in the limiting plate. A filter cartridge is fixedly inserted into the vertical groove. A screen is fixedly fixed at the bottom of the filter cartridge. A feed pipe is fixedly fixed at the top of the filter cartridge. A precision filter element is fixedly connected inside the filter cartridge. The width of the screen is equal to the width of the precision filter element. The bottom of the precision filter element is fixedly connected to the screen. Four sets of through grooves are arranged inside the bottom of the shell, and a base is placed at the top of the through groove. A vertical rod is fixed to the left side of the top of the base. Slots are respectively arranged on both sides of the through groove, and a locking block is fixedly inserted into the slot. A base plate is fixed between the bottoms of the locking blocks. A bent pipe is fixed inside the base.

[0007] As a further technical solution of this utility model, the bent pipe passes through the center of the base plate, and the bottom of the filter cylinder overlaps the base.

[0008] As a further technical solution of this utility model, a horizontal plate is fixed on both sides of the front surface of the shell, and an air pump is fixed on the horizontal plate. A three-way pipe is fixed between the input end of the air pump and the horizontal plate, and flexible hoses are fixed between the bottom two sides of the three-way pipe and the bend pipe.

[0009] As a further technical solution of this utility model, a top plate is movably connected to the right side of the top of the outer shell, and four sets of slots are provided inside the top plate. A sleeve is fixed at the rear of the slot, and slides are fixed on both sides of the slot. A locking plate is movably connected between the slides. Screw holes are provided inside the locking plate and at the front of the top plate, and bolts are longitudinally threaded between the screw holes. The feed tube is embedded between the sleeve and the locking plate. Insertion holes are provided on both sides of the front end of the sleeve, and insertion blocks are fixed on both sides of the rear of the locking plate.

[0010] As a further technical solution of this utility model, the two sides of the card plate are respectively embedded in the slide rail, and the card plate moves back and forth along the inner wall of the slide rail.

[0011] As a further technical solution of this utility model, the insert is embedded in the insertion hole, and the curvature of the sleeve and the plate matches the feed tube.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the precision dust collector for the production of double trihydroxyl not only achieves multiple dust extraction points and facilitates cleaning of the extraction mechanism, but also prevents the air inlet from shaking.

[0013] (1) By fixing the filter cartridges inside the vertical groove, unscrewing the top plate, passing each filter cartridge through the vertical groove and fixing it in the groove above the base, holding the left vertical rod, the base and filter cartridges can be vertically pulled out for cleaning and replacement. Gas and mixture will be introduced into the filter cartridges through the feed pipe, excess gas will flow out through the bend pipe, and dust particles will remain in the filter cartridges. The base plate is embedded in the slot through the clip, which can prevent the bend pipe from falling off the filter cartridge due to the airflow. Four dust extraction pipes at different locations can be connected to the feed pipe, and the dust in four sets of devices can be cleaned in one go.

[0014] (2) By fixing an air pump on the horizontal plate, the two sets of air pumps are connected to the two sets of hoses below by a three-way pipe, and the hoses are fixed at the bends. The feed pipe at the top of the filter cartridge is connected to the slot of the device to be dusted by a pipe. After the air pump is started, gas and dust particles can be drawn into the filter cartridge to filter the residue. Excess gas is discharged through the air pump, which saves electricity and ensures suction efficiency, and can clean the residue inside the device to the greatest extent.

[0015] (3) A top plate is movably connected to the right side of the top of the outer shell. The inner wall of the sleeve is attached to the back of the feed pipe. The card plate is pushed into the slide on both sides of the slot. After aligning with the screw hole, the bolt is screwed in for reinforcement. The feed pipe at the main center is fixed from the front and rear to prevent the filter cartridge from shaking after extracting gas and dust, maintain the stability of the suction operation, and facilitate the removal of the card plate, the unscrewing of the top plate and the removal of the internal structure.
