Description

Technical Field

[0001] The invention belongs to the field of pipeline engineering design, and in particular relates to a mixer and an application thereof. Background Art

[0002] In engineering design, it is often necessary to mix two or more materials through a mixer to achieve uniform composition and easy reaction after mixing. During mixing, the mixer is usually inserted into the main pipeline, and the medium enters the main pipeline from the mixer to achieve mixing of the medium and the fluid in the main pipeline.

[0003] Existing mixers such as Figure 1 As shown, it includes an insertion tube and a nozzle 101 arranged at the lower end of the insertion tube. The insertion tube is inserted into the main pipeline through the insertion port on the main pipeline, and the nozzle 101 is located in the main pipeline. In this way, the medium is input into the main pipeline through the insertion tube and the nozzle 101, so that the medium is mixed with the fluid in the main pipeline.

[0004] However, for some media containing tiny particles, the mixing effect of existing mixers is not ideal because the nozzle is only facing one direction and the tiny particles can easily clog the nozzle, thereby causing the mixer to be unusable. Summary of the invention

[0005] The purpose of the present invention is to solve the above-mentioned problems existing in the prior art and to provide a mixer and its application, which can reduce the cost and achieve sufficient mixing of the medium and the fluid and is not easy to be blocked.

[0034] The present invention is further described in detail below in conjunction with the accompanying drawings:

[0035] like Figure 2As shown, the present invention improves the existing mixer by changing the nozzle structure into a porous structure, which can ensure the long-term normal and stable operation of the device.

[0036] The embodiments of the mixer of the present invention are as follows:

[0037] Embodiment 1:

[0038] like Figure 2 As shown, the mixer of this embodiment includes: an insertion tube 2, the insertion tube 2 is a tubular structure with an upper end open, and at least two slots 4 are opened on the tube wall of the insertion tube 2, and the slots 4 connect the central through hole of the insertion tube with the outside. The slots 4 can be holes of various shapes, such as rectangular holes, waist-shaped holes, long oval holes, etc.

[0039] Preferably, the slots 4 are rectangular holes, which are easy to locate and process, and are not easily blocked for granular media and polymerizable media. The length direction of the slots 4 is parallel to the central axis of the insertion tube 2, and multiple slots 4 are evenly distributed on the tube wall of the insertion tube along the circumferential direction.

[0040] The width of the slot 4 is 2 mm to 6 mm, preferably, the width of the slot 4 is 4 mm. The length of the slot 4 is 100 mm to 200 mm, preferably, the length of the slot 4 is 150 mm. The number of the slots 4 is 4 to 8, preferably, the number of the slots 4 is 6, and the center lines of two adjacent slots are 60 degrees apart on the circumference.

[0041] Embodiment 2:

[0042] The bottom of the insertion tube 2 is a closed end, and a bottom hole 5 coaxial with the insertion tube 2 is opened on the closed end. The bottom hole 5 has a smaller diameter than the central through hole of the insertion tube and is connected to the central through hole of the insertion tube.

[0043] Preferably, the diameter of the bottom hole 5 is 6 mm. Specifically, the closed end can be an integral structure with the insertion tube 2, that is, a tubular structure with an open upper end and a closed lower end is adopted, and a bottom hole coaxial with the lower end is provided, or an end plate with a bottom hole is welded at the lower end of the insertion tube 2 as the closed end of the insertion tube 2.

[0044] Embodiment 3:

[0045] In order to facilitate the installation and removal of the insertion tube, a mounting handle 1 is provided at the upper end of the insertion tube 2. The mounting handle 1 includes: a connecting ring, and a handle fixedly connected to one side of the connecting ring. The connecting ring is an annular structure, which is coaxially arranged with the insertion tube 2. The lower end face of the connecting ring is connected to the upper end face of the insertion tube 2. The diameter of the outer ring of the connecting ring is larger than the outer diameter of the insertion tube 2, and the diameter of the inner ring of the connecting ring is the same as the aperture of the central through hole of the insertion tube 2, so that the central through hole of the connecting ring is connected to the central through hole of the insertion tube. Specifically, an outward annular flange can be directly provided at the upper end opening of the insertion tube 2 as a connecting ring, and a handle can be connected to one side of the annular flange.

[0046] Embodiment 4:

[0047] This embodiment provides an application of a mixer in acetic acid treatment. During installation, a flange is first set below the flange of the insertion port of the main pipeline 3 of the acetic acid treatment device, and then the insertion tube 2 is inserted into the insertion port of the main pipeline 3 through the installation handle 1, so that the lower end surface of the connecting ring in the installation handle 1 is supported by the flange of the insertion port, and then a flange is set above the connecting ring, and bolts are passed through the two flanges to fix the connecting ring between the two flanges (annular gaskets can be set between the flange and the connecting ring, and between the connecting ring and the flange of the insertion port of the main pipeline, and the flange, gasket, connecting ring, and insertion tube are coaxially arranged.), and then the insertion tube 2 is fixed, and the slot 4 on the insertion tube 2 is located in the main pipeline 3. The medium is injected into the insert tube 2 through the pipeline, and the fluid is introduced into the main pipeline 3 at the same time. The medium in the insert tube 2 flows out through the multiple slots 4 on the insert tube 2. Since the slots 4 are evenly distributed along the circumferential direction, the medium in the insert tube 2 enters the main pipeline 3 evenly along the distribution direction of the slots, so that the medium and the fluid are mixed more evenly, and the slots 4 are rectangular holes and are not easily blocked by tiny particles. In addition, if part of the medium containing tiny particles is deposited at the bottom of the insert tube 2, the tiny particles can flow out through the bottom hole 5, which avoids the accumulation of tiny particles at the bottom of the insert tube 2 and further ensures that the mixer is not easily blocked.

[0048] When processing acetic acid, if the existing mixer is installed in the acetic acid processing device, the mixer will be blocked three times within one year of operation. At this time, the valve at the front end of the pipeline connected to the mixer can only be temporarily cut off, and then the nozzle can be replaced and repaired, which will cause production suspension, thereby affecting the quality of the product and causing economic losses. In addition, the nozzle blockage needs to be checked frequently. After the present invention is installed in the acetic acid processing device, since tiny particles can enter the main pipeline from the slot holes and the bottom holes, the mixer is not easily blocked, thereby ensuring the normal and stable operation of the device. In addition, the medium enters the main pipeline from multiple directions, making the mixing of the medium and the fluid more uniform. The device has been in operation for more than one year without any economic losses caused by mixer blockage.

[0049] In summary, the mixer of the present invention, by providing the slot holes 4 and the bottom holes 5, can achieve sufficient mixing of the fluid and the medium containing tiny particles, avoids clogging of the mixer, and thus ensures long-term normal and stable operation of the device.

[0050] In addition, the existing mixer uses a nozzle, and the cost of the nozzle accounts for about 20% to 25% of the overall cost of the mixer. However, the present invention does not require the use of a nozzle, and only requires processing a plurality of slots on the insertion tube, thereby greatly reducing the cost of the mixer.
