Description

Technical Field

[0001] The utility model relates to the field of filtering equipment, in particular to a glycerin precision filter. Background Art

[0002] Filtration is the process of purifying fluids through special devices. There are many ways to filter, and the material systems used are also very wide. Solid-liquid, solid-gas, large particles, and small particles are all very common. In many industrial productions, glycerol is an important raw material or intermediate product, and its quality is crucial. Filtration equipment is a mechanical device or device used for filtration. It is a common general-purpose equipment in industrial production and can be widely used in production links in chemical, pharmaceutical, food and other industries that require high glycerol purity.

[0003] At present, in the process of using filters to filter glycerin, there are some deficiencies in the filtering equipment when processing glycerin. Some filtering equipment is prone to filter blockage during the filtering process, and the filtering efficiency is low, which cannot meet the needs of large-scale production and needs to be replaced in time. However, the installation operation of the filter element is relatively complicated. When replacing it, the operation difficulty and replacement time are increased, which is not conducive to continuous use. For this reason, we propose a glycerin precision filter to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a glycerin precision filter to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A glycerin precision filter comprises a square shell, the outer surface of which is provided with a square opening, the interior of the square shell is provided with a square frame, the interior of the square frame is respectively provided with a pre-filtration layer, a fine filtration layer and an ultrafiltration layer, the outer surface of the square frame is fixedly connected to two positioning blocks with holes, the left side of the square shell is fixedly connected to a square box, the inner wall of the square box is fixedly connected to a circular long rod, the outer surface of the circular long rod is fixedly connected to a fixed block, the outer surface of the fixed block is fixedly connected to two springs, the outer surface of the circular long rod is slidably connected to two movable sliders, each of the springs is fixedly connected to the outer surface of the movable slider at one end away from the fixed block, the bottom end of each movable slider extends to the bottom of the square box, the outer surface of each movable slider is fixedly connected to a limiting block, and the limiting block matches the positioning block with holes, and the outer surface of each movable slider is fixedly connected to a T-shaped pull block.

[0007] In a further embodiment, the outer surface of the square box is provided with openings adapted to the T-shaped pull block and the movable slider, and each of the T-shaped pull blocks is located on the left side of the square box.

[0008] In a further embodiment, the upper surface of the square shell is fixedly connected to a liquid inlet pipe, and the bottom surface of the square shell is fixedly connected to a liquid outlet pipe.

[0009] In a further embodiment, a flow guide scoop is fixedly connected to the inner wall of the square shell, and the flow guide scoop is located above the square frame.

[0011] In a further embodiment, two slide grooves are provided on the inner wall of the square shell, and two guide bars are fixedly connected to the outer surface of the square frame, and the guide bars match the slide grooves.

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

[0013] This device forms a multi-layer filtration system by means of a pre-filtration layer, a fine filtration layer and an ultrafiltration layer arranged inside a square frame. The pre-filtration layer can first intercept larger impurity particles in the glycerin to play a preliminary purification role. The fine filtration layer further performs a finer filtration on the glycerin after pre-filtration to remove smaller impurities and improve the purity of the filtrate. The ultrafiltration layer can screen and filter smaller molecules or particles to ensure that the glycerin discharged from the outlet pipe meets a higher precision filtration standard and meets application scenarios with higher requirements for glycerin purity.

[0014] The device can be installed conveniently and accurately in the square shell by matching the positioning block with holes and the limit card block on the square skeleton and cooperating the guide bar and the slide groove. The operator only needs to align the square skeleton along the guide bar and put it into the square shell, and make the limit card block snap into the positioning block with holes to complete the installation. The operation is simple and quick, saving installation time and labor costs. By pulling the T-shaped pull block, the movable slider can overcome the elastic force of the spring to move, so that the limit card block is separated from the positioning block with holes. At this time, the square skeleton can be easily removed from the square shell. This design makes the disassembly process of the filter element simple and easy, which is convenient for the staff to replace the aging or damaged filter layer in time, reduces the maintenance difficulty and downtime of the equipment, and ensures the normal operation of the glycerin precision filtration equipment.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0023] 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.

[0024] For example, see Figure 1-5 In the utility model, a glycerin precision filter comprises a square shell 1, the outer surface of the square shell 1 is provided with a square opening 5, the interior of the square shell 1 is provided with a square skeleton 6, the interior of the square skeleton 6 is respectively provided with a pre-filtration layer 12, a fine filtration layer 13 and an ultrafiltration layer 14, the outer surface of the square skeleton 6 is fixedly connected with two positioning blocks 9 with holes, the left side of the square shell 1 is fixedly connected with a square box 4, the inner wall of the square box 4 is fixedly connected with a circular long rod 16, the outer surface of the circular long rod 16 is fixedly connected with a fixed block 17, the outer surface of the fixed block 17 is fixedly connected with two springs 18, the outer surface of the circular long rod 16 is slidably connected with two movable sliders 19, one end of each spring 18 away from the fixed block 17 is fixedly connected to the outer surface of the movable slider 19, the bottom end of each movable slider 19 extends to the bottom of the square box 4, the outer surface of each movable slider 19 is fixedly connected with a limiting block 21, and the limiting block 21 matches the positioning block 9 with holes, and the outer surface of each movable slider 19 is fixedly connected with a T-shaped pull block 20.

[0025] Specifically, the pre-filtration layer 12 uses a polypropylene fiber membrane with a pore size of [5-10] μm, which can effectively intercept large particle impurities and some colloids. The fine filtration layer 13 uses a polyethersulfone membrane with a pore size of [1-5] μm, which can further remove smaller particles and some microorganisms. The ultrafiltration layer 14, whose ultrafiltration membrane pore size is less than 1 μm, can intercept most colloids, microorganisms and macromolecular impurities, ensuring that the glycerol reaches a high purity. The operator only needs to align the square skeleton 6 along the guide bar 11 with the slide groove 10 and put it into the square shell 1, and make the limit block 21 snap into the perforated positioning block 9 to complete the installation. The operation is simple and fast, saving installation time and labor costs. By pulling the T-shaped pull block 20, the movable slider 19 can overcome the elastic force of the spring 18 to move, so that the limit block 21 is separated from the perforated positioning block 9. At this time, the square skeleton 6 can be easily removed from the square shell 1. This design makes the disassembly process of the filter element simple and easy, convenient for the staff to replace the aging or damaged filter layer in time, and reduces the maintenance difficulty and downtime of the equipment.

[0026] Embodiment 2 is an improvement on the previous embodiment.

[0027] Specifically, the outer surface of the square box 4 is respectively provided with openings compatible with the T-shaped pull block 20 and the movable slider 19, and each T-shaped pull block 20 is located on the left side of the square box 4, so that the movable slider 19 can move more smoothly. The upper surface of the square shell 1 is fixedly connected with a liquid inlet pipe 2, and the bottom surface of the square shell 1 is fixedly connected with a liquid outlet pipe 3, which is convenient for taking the liquid to be filtered through the liquid inlet pipe 2 and discharging the filtered liquid through the liquid outlet pipe 3. The inner wall of the square shell 1 is fixedly connected with a guide bucket 7, and the guide bucket 7 is located above the square frame 6. When glycerol enters the square shell 1 from the liquid inlet pipe 2, the guide bucket 7 can effectively guide the inflowing glycerol to make it evenly distributed on the pre-filter layer 12, avoiding the problem of excessive or insufficient local filtration pressure due to uneven liquid inflow, ensuring that each filter layer can give full play to its filtering effect and improve the filtering efficiency.

[0028] Specifically, a seal 15 is fixedly connected to the outer surface of the square skeleton 6, and a pull frame 8 is fixedly connected to the right side of the square skeleton 6, so that the square skeleton 6 is more sealed after installation, ensuring the sealing effect during filtration, ensuring that a good sealing environment is formed between each filter layer and the square shell 1, and preventing glycerin from leaking during the filtration process. Two slide grooves 10 are provided on the inner wall of the square shell 1, and two guide bars 11 are fixedly connected to the outer surface of the square skeleton 6, and the guide bars 11 are matched with the slide grooves 10. It is only necessary to align the square skeleton 6 with the slide grooves 10 along the guide bars 11 and put it into the square shell 1, which is convenient for installation and disassembly, thereby providing precise guidance and stable support for the placement of the square skeleton 6 in the square shell 1.

[0029] The working principle of the utility model is:

[0030] When in use, the glycerin product to be filtered is taken in by the liquid inlet pipe 2, and falls downward along the guide bucket 7. After multi-layer filtration of the pre-filtration layer 12, the fine filtration layer 13 and the ultrafiltration layer 14, the discharged glycerin can reach a higher precision filtration standard and meet the application scenarios with high requirements for glycerin purity. When the filter element needs to be replaced, the movable slider 19 can be moved on the round long rod 16 by the T-shaped pull block 20 to overcome the elastic force of the spring 18, and the limit block 21 can be moved out of the perforated positioning block 9, and then the square frame 6 is pulled to the right from the square shell 1 by the pull frame 8 to complete the disassembly of the square frame 6. After the filter element is replaced, the guide strip 11 on the square frame 6 is inserted into the square shell 1 along the slide groove 10, and then the movable slider 19 and the limit block 21 are moved by the T-shaped pull block 20 to make the limit block 21 inserted into the perforated positioning block 9 again, so as to complete the replacement and installation operation of the filter element, thereby reducing the difficulty of the replacement operation.
