Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of filtering devices, in particular to a laboratory porous rapid filtering device. Background Art
[0002] Existing laboratory filtration devices generally have one or two filter discs and operate intermittently. During laboratory tests, multiple samples are often produced at the same time, and most of them are wet operations, so the materials need to be filtered before the next step. At the same time, fine-grained tailings or raw materials that may be produced during the test contain a lot of fine mud. Due to the fine particle size, solid-liquid separation is more difficult, and sometimes a long time of filtration is required, which can easily lead to a backlog of filtered samples and affect the progress of the test.
[0003] To address the above issues, we can purchase multiple filtering devices or high-power filtering devices. However, during laboratory tests, the sample volume is basically small, and high-power filtering devices will cause large sample losses. Adding filtering devices can improve filtration efficiency, but the floor space and cost are higher. Utility Model Content

[0020] 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.
[0021] The utility model aims to provide a laboratory porous rapid filtering device to solve the problems existing in the prior art, occupy a small space, have low cost, and can greatly improve the processing efficiency of the filtering device.
[0022] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0023] like Figure 1 As shown, this embodiment provides a laboratory porous rapid filtration device, including a pressure tank body 1, a vacuum pump 2, a filter disc 3 and a sealing switch 4. The pressure tank body 1 is connected to the vacuum pump 2. A plurality of branch pipes 5 are provided on the pressure tank body 1. The upper end of each branch pipe 5 is connected to a filter disc 3, and the filter disc 3 is provided with a suction hole connected to the branch pipe 5. Each branch pipe 5 is provided with a sealing switch 4.
[0024] In this embodiment, the pressure tank body 1 includes a circular steel tube 11 and a sealing plate 12 , and both ends of the circular steel tube 11 are sealed by the sealing plate 12 .
[0025] In this embodiment, the branch pipes 5 are connected to the upper side of the circular steel pipe 11 at intervals along the axial direction of the circular steel pipe 11 .
[0026] In this embodiment, the pressure tank body 1 and each branch pipeline 5 are made of stainless steel.
[0027] In this embodiment, the inner walls of the pressure tank body 1 and each branch pipe 5 are provided with an anti-corrosion coating.
[0028] In other embodiments, the pressure tank 1 can also be set as a square ring tank ( Figure 2 as shown) or annular tank ( Figure 3 shown).
[0029] The number of branch pipes 5 and the size of the filter disc 3 can also be adjusted according to actual test needs and site size. Each filter disc 3 can operate simultaneously or individually. When operating individually, other sealing switches 4 that are not operating are in a closed state to prevent air leakage from affecting the filtering efficiency.
[0030] This device uses a vacuum pump 2 to generate negative pressure to achieve solid-liquid separation. The actual operation is as follows: first, place filter paper with appropriate water permeability in the filter disc 3, then place the slurry that needs solid-liquid separation in the filter disc 3, turn on the sealing switch 4, sealing water and vacuum pump 2 in sequence, and after the filtration is completed, turn off the vacuum pump 2, and take out the filter paper and filter cake at the same time to complete the sample filtration process. Among them, the sealing water is used by the vacuum pump 2. The working principle of the vacuum pump 2 is to use a fan blade similar to a propeller to extract air. There is a gas backflow prevention device at the air outlet. Since there is a certain gap between the fan blade of the vacuum pump 2 and the inner wall, it will cause air leakage, so water is added to fill the gap in a centrifugal manner to play a sealing role.
[0031] This device has the following advantages:
[0032] 1. This device uses multiple filter discs to work in parallel but relatively independently. Under the conditions of smaller space and lower cost, it greatly improves the processing efficiency of the filter device and can also meet the needs of single sample filtering operations.
[0033] 2. The device can adjust the shape, size, filter disc size, etc. of the tank according to different laboratory conditions. It has a simple structure and strong adaptability.
[0034] 3. The main body of the device can be manufactured with ordinary steel pipes. A hole is opened on one side and a branch pipe is connected. No special materials or special processes are required, and the manufacturing process is simple. If special materials need to be processed, such as strong acids, strong alkalis, and highly corrosive samples, corresponding resistant materials or anti-corrosion coatings can be used to reduce system or equipment losses.
[0035] The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of the present invention. At the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
