Description

Technical Field

[0001] The utility model belongs to the technical field of hydrogenated rosin glycerol ester filtering, in particular to a hydrogenated rosin glycerol ester filtering device. Background Art

[0002] In the production process of hydrogenated rosin glycerol ester, esterification reaction is a key step. However, this process is not always smooth. In the production process, partial coking often occurs. Coking is a chemical reaction that occurs under high temperature conditions, usually due to excessive temperature or incomplete contact of the reactants, resulting in the production of coked substances.

[0003] These charred materials will affect the performance and appearance of the finished product quality of hydrogenated rosin glycerol ester, so in the production process, these charred materials and hydrogenated rosin glycerol ester need to be separated before the next process.

[0004] Since the coking materials are often highly viscous and easy to adhere, it is difficult for them to be effectively filtered out by physical filters. Once the coking materials adhere to the filter, it will not only cause the filter to be blocked, but also reduce production efficiency, increase production costs, and may cause damage to the equipment. The filters in the prior art are often inefficient when filtering rosin glycerol esters, and the operation is difficult and intensive. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a hydrogenated rosin glycerol ester filtering device, which is used to reduce the difficulty and intensity of the operation in the process of filtering the coked material of the rosin glycerol ester.

[0006] It comprises: a filter cartridge and a filter bag, wherein the filter cartridge is fixed with a filter bag, and the filter bag is used to filter the coked substances in hydrogenated rosin glycerol ester;

[0007] The inner wall of the filter cartridge is provided with an annular boss for supporting the filter bag, the annular boss is provided with a bag pressing flange, the annular boss and the bag pressing flange are connected by threads or snaps, the opening edge of the filter bag is fixed on the bag pressing flange, and a handle is provided at the bottom of the bag pressing flange.

[0008] Preferably, the pressing bag flange is provided with a lifting threaded hole penetrating the pressing bag flange, and a lifting bolt is installed in the lifting threaded hole, and the length of the lifting bolt is equal to the thickness of the pressing bag flange.

[0009] Preferably, the lifting bolt is a ball screw.

[0010] Preferably, a protruding anti-slip barb is provided at the lower end of the lifting bolt, and an avoidance groove for accommodating the anti-slip barb is provided on the annular boss.

[0011] Preferably, a V-shaped ring groove is provided on the top surface of the annular boss, a sealing gasket is provided at the bottom of the V-shaped ring groove, and a V-shaped positioning block corresponding to the V-shaped ring groove is provided on the bag pressing flange.

[0014] 1. The opening edge of the filter bag is fixed on the bag pressing flange. A handle is provided at the bottom of the bag pressing flange, which can conveniently disassemble and assemble the filter bag outside the filter cartridge, avoiding complicated operations in the narrow filter cartridge space and improving disassembly and assembly efficiency.

[0015] 2.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example

[0021] The utility model provides a hydrogenated rosin glycerol ester filtering device, comprising: a filter cartridge 1, a filter bag 2, wherein the filter cartridge 1 is fixedly provided with the filter bag 2, and the filter bag 2 is used for filtering the coked material in the hydrogenated rosin glycerol ester; the inner wall of the filter cartridge 1 is provided with an annular boss 3 for supporting the filter bag 2, and a bag pressing flange 4 is provided on the annular boss 3, and the annular boss 3 and the bag pressing flange 4 are connected by threads or buckles, the opening edge of the filter bag 2 is fixed on the bag pressing flange 4, and a handle is provided at the bottom of the bag pressing flange 4, and the opening edge of the filter bag 2 is fixed on the bag pressing flange 4, and a handle is provided at the bottom of the bag pressing flange 4, so that the filter bag 2 can be conveniently disassembled and assembled outside the filter cartridge 1, and complicated operations in the narrow space of the filter cartridge 1 are avoided, thereby improving the disassembly and assembly efficiency.

[0022] The pressing bag flange 4 is provided with a lifting threaded hole 5 that penetrates the pressing bag flange 4, and a lifting bolt 6 is installed in the lifting threaded hole 5. The length of the lifting bolt 6 is equal to the thickness of the pressing bag flange 4. When the pressing bag flange 4 and the annular boss 3 are strongly adhered to each other and cannot be lifted by the handle, the lifting thread installed on the pressing bag flange 4 can be used to separate the pressing bag flange 4 and the annular boss 3 by twisting the lifting thread downward. The lifting bolt 6 has two advantages that the length of the lifting bolt 6 is equal to the thickness of the pressing bag flange 4. First, it can be confirmed whether the lifting bolt 6 will interfere with the installation of the pressing bag flange 4 and the annular boss 3 by the situation that the top of the lifting bolt 6 protrudes from the top of the pressing bag flange 4. That is, when the top of the lifting bolt 6 protrudes from the top of the pressing bag flange 4, it means that the bottom of the lifting bolt 6 will not protrude from the bottom of the pressing bag flange 4, and the pressing bag flange 4 and the annular boss 3 can be installed in a close fit. At this time, the lifting bolt 6 will not interfere with the installation of the pressing bag flange 4 and the annular boss 3.

[0023] The lifting bolt 6 is a ball screw. When the ball screw is screwed down to lift the bag pressing flange 4 to separate the bag pressing flange 4 and the annular boss 3, the ball on the ball screw can reduce the contact friction with the annular boss 3 and protect the contact surface of the annular boss 3.

[0024] The lower end of the lifting bolt 6 is provided with a protruding anti-detachment hook 7, which can keep the lifting bolt 6 on the bag pressing flange 4. The annular boss 3 is provided with an avoidance groove 8 for accommodating the anti-detachment hook 7.

[0025] A V-shaped ring groove 9 is provided on the top surface of the annular boss 3, a sealing gasket is provided at the bottom of the V-shaped ring groove 9, and a V-shaped positioning block 10 corresponding to the V-shaped ring groove 9 is provided on the bag pressing flange 4. The V-shaped ring groove 9 and the V-shaped positioning block 10 can provide guiding positioning when the bag pressing flange 4 is installed on the annular boss 3, thereby reducing the difficulty of installation and facilitating the installation of the sealing gasket.

[0026] The material of the bag pressing flange 4 is polytetrafluoroethylene, which is resistant to acid, alkali and various organic solvents, and is almost insoluble in all solvents. It is extremely suitable for use in the environment of hydrogenated rosin glycerol ester. At the same time, polytetrafluoroethylene is resistant to high temperatures, has a very low friction coefficient, has self-lubricating properties, is not prone to wear during installation and disassembly, and can extend the service life.

[0027] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
