Description

Technical Field

[0001] The utility model relates to the technical field of filtration, and more particularly to a filtering and water absorbing device. Background Art

[0002] Nowadays, in the field of food inspection, the detection of food fat content generally adopts the filtration and water absorption method. This method generally involves first soaking the food sample in petroleum ether to dissolve the fat in the sample, and then pouring the solution into a funnel covered with filter paper (such as the prior art such as CN208097517U-A filtering device for food inspection, CN221107184U-A liquid separation and filtration device for food inspection samples), filtering the residue in the solution, and then absorbing the filtered solution with sodium sulfate to remove the water in the solution, and then evaporating the petroleum ether to obtain the fat content.

[0003] However, the filtration and water absorption process is all done manually, which is slow and difficult to control quality, and is not suitable for automated filtration and water absorption operations.

[0004] Therefore, how to provide a filtering and water absorption device that does not require manual operation for filtering and water absorption, can be directly connected to automated facilities for direct use, and improves detection efficiency is a problem that technical personnel in this field urgently need to solve. Utility Model Content

[0005] In view of this, the utility model provides a filtering and water absorbing device that does not require manual operation for filtering and absorbing water and can be directly connected to an automated facility for direct use to improve detection efficiency.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A filtering and water absorption device can remove water and residue from a mixed liquid to obtain the required liquid components. The device includes:

[0008] A lower shell body, wherein the interior of the lower shell body has a filter cavity penetrating the upper and lower end surfaces, and the lower cavity opening of the filter cavity is a liquid inlet;

[0009] An upper cover body, wherein the upper cover body has an accommodating cavity with an open bottom end, the open cover of the accommodating cavity is connected to the upper cavity opening of the filter cavity, and a liquid outlet communicating with the accommodating cavity is opened on an outer wall of one side of the upper cover body;

[0010] A filtering and water absorbing component is fixed between the filtering cavity and the accommodating cavity.

[0011] As can be seen from the above technical solution, compared with the prior art, the present invention provides a filtering and water-absorbing device. During use, a mixed solution (such as a solution containing petroleum ether, grease, water, and food sample residue) enters the filter chamber through the liquid inlet. After passing through the filtering and water-absorbing component, the food sample residue is filtered out and the water in the mixed solution is absorbed. Afterwards, the remaining liquid flows out through the liquid outlet to the next process for further processing. Therefore, the integrated filtering and water-absorbing component of the device can automatically remove water and residue from the mixed solution, eliminating the need for manual filtering and water absorption, thereby improving detection efficiency.

[0012] Furthermore, the filtering and water absorbing component includes:

[0013] A lower filter screen, the lower filter screen being fixed on the inner wall of the filter cavity;

[0014] A water absorbing layer is provided on the top surface of the lower filter screen.

[0015] The beneficial effect of adopting the above technical solution is that the lower filter first filters out the residual particles in the solution, and then the filtered solution enters the water absorption layer to remove moisture, and then flows out through the liquid outlet to the next process for further processing.

[0016] Furthermore, the water absorption layer is a sodium sulfate powder layer, and the filtering and water absorption component further comprises:

[0017] Lower filter paper, the lower filter paper is laid on the top surface of the lower filter screen, and the water absorption layer is laid on the top surface of the lower filter paper;

[0018] Upper filter paper, the upper filter paper is laid on the top surface of the water absorbing layer;

[0019] An upper filter screen is pressed onto the top surface of the upper filter paper and is fixed on the inner wall of the filter cavity.

[0020] The beneficial effects of the above technical solution are as follows: the lower filter screen filters out larger residual particles in the solution, followed by the lower filter paper filtering out fine particles in the solution. The solution is then mixed with sodium sulfate to remove moisture, and then filtered again by the upper filter paper and the upper filter screen before flowing out of the liquid outlet. Therefore, this device can achieve coarse filtration, fine filtration, and moisture removal of the solution without manual operation. Furthermore, the lower filter screen supports the lower filter paper, preventing it from being crushed by the sodium sulfate. The upper filter paper prevents sodium sulfate powder from being washed away by the solution, and the upper filter screen presses and supports the upper filter paper, preventing it from being damaged by excessive liquid impact.

[0021] Furthermore, the inner wall of the filter cavity has a bearing step, the inner wall of the accommodating cavity has a crimping step, and the lower filter screen, the lower filter paper, the water absorption layer, the upper filter paper, and the upper filter screen are sequentially crimped between the bearing step and the crimping step.

[0022] The beneficial effect of adopting the above technical solution is that after the lower shell and the upper cover are connected, the pressing step and the bearing step can press and seal the filter and water absorption assembly, ensuring the stability of the installation and sealing of the filter assembly.

[0023] Furthermore, it also includes a spacer, which is placed between the lower filter paper and the upper filter paper, and the water absorption layer is accommodated in the spacer.

[0024] The beneficial effects of the above technical solution are: the spacer not only accommodates the sodium sulfate powder but also serves as a force-bearing member for the compression force between the crimping step and the supporting step, absorbing the sealing pressure, thereby ensuring that the filter and water absorption assembly can be compressed between the crimping step and the supporting step. Furthermore, by providing the spacer with an appropriate height, a sufficient amount of sodium sulfate can be accommodated and evenly distributed within the spacer.

[0025] Furthermore, a filter mesh plate is provided inside the filter cavity below the lower filter mesh.

[0026] The beneficial effect of adopting the above technical solution is that after the solution enters the lower shell through the liquid inlet, it first filters out larger impurities through the filter mesh plate, and then enters the lower filter mesh, lower filter paper, water absorption layer, and upper filter paper in sequence for re-filtration, thereby improving the solution filtration effect.

[0027] Furthermore, the space in the filter cavity between the filter mesh plate and the lower filter mesh is a lower buffer cavity.

[0028] The beneficial effect of adopting the above technical solution is that: after the solution passes through the filter mesh plate, it enters the lower buffer chamber for buffering. At this time, the solution becomes uniform in the lower buffer chamber, and the solution pressure is also uniform. Then, when the pressure-equalized liquid enters the lower filter mesh, the lower filter paper, the sodium sulfate, and the upper filter paper, because the filter holes on the lower filter mesh, the lower filter paper, and the upper filter paper are all evenly distributed, the sodium sulfate particles are also evenly distributed. Each filter hole and each sodium sulfate particle are working, and the workload is also uniform. Some will not work or work less, and congestion caused by some filter holes filtering too much solution is avoided, resulting in a decrease in overall filtration quality and efficiency.

[0029] Furthermore, the space above the upper filter screen in the accommodating chamber is an upper buffer chamber.

[0030] The beneficial effects of adopting the above technical solution are: it also plays the role of uniform and equal pressure of the liquid after filtering and absorbing water, which facilitates uniform filtration and water absorption of upstream liquid and also facilitates uniform flow of liquid out of the filtering and absorbing device.

[0031] Furthermore, the top outer wall of the lower shell body is provided with an external thread, the bottom inner wall of the upper cover body is provided with an internal thread, and the internal thread is screwed and fixed to the external thread.

[0032] The beneficial effects of adopting the above technical solution are: easy disassembly and assembly of the lower shell and the upper cover, and convenient disassembly and assembly and replacement of the filtering and water absorbing assembly.

[0033] Furthermore, the bottom of the lower shell has an installation step connected to external facilities.

[0034] The beneficial effect of adopting the above technical solution is that the device can be installed in external facilities (such as an automatic detection system, the liquid inlet is connected to the liquid inlet pipe in the system, and the liquid outlet is connected to the liquid outlet pipe in the system, which can realize automatic liquid inlet and outlet) to achieve automated operation.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] As previously mentioned, in the field of food testing, the oil content of food is tested by dissolving the oil in the food with petroleum ether, then manually filtering out the residue in the solution, and then absorbing water with sodium sulfate. Each step is manual, slow, and difficult to control quality, making it unsuitable for automated operation. Therefore, the present utility model provides a filtering and water absorption device to improve the quality and speed of filtration testing and make it suitable for automated operation.

[0043] The following will introduce the application of the filtering and water absorption device provided by the utility model in the field of food testing.

[0044] like Figure 1-Figure 5 As shown, the embodiment of the utility model discloses a filtering and water absorbing device, comprising:

[0045] The lower shell 1 has a filter cavity running through the upper and lower end surfaces. The lower cavity opening of the filter cavity is a liquid inlet 102. The liquid inlet 102 can be connected to other area facilities, sealed and filled with liquid;

[0046] The upper cover body 6 has an open bottom accommodating cavity inside, and the open cover of the accommodating cavity is connected to the upper cavity opening of the filter cavity. A liquid outlet 106 communicating with the accommodating cavity is opened on the outer wall of one side of the upper cover body 6. The liquid outlet 106 can be connected to other area facilities, sealed and discharge liquid;

[0047] The filtering and water absorbing component is fixed between the filtering cavity and the accommodating cavity.

[0048] In some specific embodiments, the filter and water absorption component includes:

[0049] The lower filter screen 2 is fixed on the inner wall of the filter cavity;

[0050] The water absorbing layer 5 is arranged on the top surface of the lower filter screen 2 .

[0051] Of course, the water absorption layer 5 is a sodium sulfate powder layer, and the filtering and water absorption component also includes:

[0052] The lower filter paper 3 is laid on the top surface of the lower filter screen 2, and the water absorption layer 5 is laid on the top surface of the lower filter paper 3;

[0053] Upper filter paper 7, which is laid on the top surface of the water-absorbing layer 5;

[0054] The upper filter screen 8 is pressed on the top surface of the upper filter paper 7 and fixed on the inner wall of the filter cavity.

[0055] There is a bearing step 109 on the inner wall of the filter cavity, and a crimping step 110 on the inner wall of the accommodating cavity. The lower filter screen 2, the lower filter paper 3, the water-absorbing layer 5, the upper filter paper 7, and the upper filter screen 8 are sequentially crimped between the bearing step 109 and the crimping step 110 to achieve the installation, fixation and sealing of the filter and water-absorbing assembly.

[0056] The filtering and water-absorbing device further comprises a spacer sleeve 4 , which is placed between the lower filter paper 3 and the upper filter paper 7 , and the water-absorbing layer 5 is accommodated in the spacer sleeve 4 .

[0057] A filter mesh plate 103 is provided in the filter chamber below the lower filter mesh 2 .

[0058] The space between the filter mesh plate 103 and the lower filter mesh 2 in the filter cavity is the lower buffer cavity 104 .

[0059] The space above the upper filter screen 8 in the accommodating chamber is the upper buffer chamber 105 .

[0060] An external thread 107 is provided on the top outer wall of the lower shell 1 , and an internal thread 108 is provided on the bottom inner wall of the upper cover 6 . The internal thread 108 is screwed and fixed to the external thread 107 .

[0061] The bottom of the lower housing 1 has an installation step 101 for connecting to external facilities.

[0062] The liquid (such as a solution containing petroleum ether, grease, water and food sample residue) enters the filtering and water-absorbing device from the liquid inlet 102. The liquid passes through the filter mesh plate 103 to filter out some larger residue particles, enters the buffer chamber 104 for uniform and equal pressure liquid, and then passes through the lower filter screen 2 and the lower filter paper 3 to remove all residue particles, and enters the sodium sulfate 5 for mixing. After the sodium sulfate 5 absorbs the moisture in the liquid, it passes through the upper filter paper 7 and the upper filter screen 8 above and enters the buffer chamber 105 in the lower cover body 6. The buffer chamber 105 maintains the liquid equal pressure, which facilitates the uniform filtration and water absorption of the upstream liquid, and also facilitates the liquid to evenly flow out of the filtering and water-absorbing device. Finally, the liquid flows out through the liquid outlet 106 on the upper cover body 6.

[0063] Therefore, during filtration, the liquid enters the device from the liquid inlet, and undergoes coarse filtration, fine filtration, water absorption, and buffering to remove foreign matter and moisture, and this process is carried out continuously.
