Description

Technical Field

[0001] The utility model relates to a gas-solid separation device. Background Art

[0002] The gas-solid separation device is generally used for the transportation of powder raw materials, and includes a separation barrel. The separation barrel is divided into a separation chamber and an air outlet chamber by a partition plate. One end of the air outlet chamber is evacuated by a blower, so as to suck the powder raw materials into the separation chamber. A cloth bag or a paper bag is installed in the separation chamber. Air enters the air outlet chamber through the cloth bag or the paper bag, but the powder raw materials cannot pass through the cloth bag or the paper bag, and thus accumulate at the bottom of the separation chamber. After leaking out from the discharge port at the bottom, they are quantitatively bagged or barreled.

[0003] The cloth bag or the paper bag in the above structure is not only easy to break, but also easy to deform during the air extraction process, resulting in a reduction in the filtration area and a decrease in the filtration effect, thereby also reducing the filtration efficiency. Therefore, the applicant designs a gas-solid separation device to solve the above situation. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a gas-solid separation device.

[0005] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0006] A gas-solid separation device includes a separation barrel and a partition plate. The separation barrel is divided into a separation chamber and an air outlet chamber by the partition plate. It is characterized in that: it further includes a metal filter element. The partition plate is provided with partition holes. The metal filter element passes through the partition holes and is located in the separation chamber, and the metal filter element is fixed to the partition plate through a detachable clamp structure.

[0007] The clamp structure includes a clamp, a lower connecting member fixed on the partition plate, and an upper connecting member fixed on the metal filter element. The lower connecting member and the upper connecting member are fixed into one body through the clamp.

[0008] The lower connecting member includes a lower connecting sleeve and a lower chuck fixed on the periphery of the lower connecting sleeve; the upper connecting member includes an upper connecting sleeve and an upper chuck fixed on the periphery of the upper connecting sleeve.

[0026] As can be fully understood by those skilled in the art, the features of different embodiments of the present disclosure may be partially or fully coupled or combined with each other, and may cooperate with each other in various ways and be technically driven. The embodiments of the present disclosure may be executed independently of each other, or may be executed together in a mutually dependent relationship.

[0027] Refer to Figures 1 to 5, the utility model discloses an air-material separation device, which comprises a separation barrel 1 and a partition plate 2. The separation barrel 1 and the partition plate 2 are preferably made of stainless steel materials. The separation barrel 1 is divided into a separation chamber 3 and an air outlet chamber 4 by the partition plate 2. The bottom of the separation chamber 3 is in a conical shape with a smaller bottom and a larger top, which is convenient for the powder raw materials to leak out from the bottom of the separation chamber 3. It also includes a metal filter element 5. There is a partition hole 6 on the partition plate 2, and the metal filter element 5 passes through the partition hole 6 and is located in the separation chamber 3. The metal filter element 5 of this application is preferably an externally purchased titanium metal powder sintered filter element. The metal filter element 5 has a filter nozzle 11, and there is a filter element port on the filter nozzle 11. The filter element port is located in the air outlet chamber 4, and the metal filter element 5 is fixed to the partition plate 2 through a detachable clamp structure. The clamp structure is convenient for later maintenance or replacement of the metal filter element 5, and the installation is also convenient.

[0028] As shown in the figure, the clamp structure includes a clamp, a lower connecting member fixed on the partition plate 2, and an upper connecting member fixed on the metal filter element 5. The lower connecting member and the upper connecting member are fixed into one body by the clamp. The lower connecting member includes a lower connecting sleeve 7 and a lower chuck 8 fixed on the periphery of the lower connecting sleeve 7; the lower connecting sleeve 7 and the lower chuck 8 are welded into one body, and then the bottom end of the lower connecting sleeve 7 is welded and fixed to the partition plate 2. The partition hole 6 is opposite to the lower connecting sleeve 7 and communicates with the lower connecting sleeve 7; the upper connecting member includes an upper connecting sleeve 9 and an upper chuck 10 fixed on the periphery of the upper connecting sleeve 9. The upper connecting sleeve 9 and the upper chuck 10 are welded into one body. Both the upper chuck 10 and the lower chuck 8 are circular plate-shaped, and both the upper connecting sleeve 9 and the lower connecting sleeve 7 are metal cylinders. However, the connection between the upper connecting sleeve 9 and the metal filter element 5 is preferably a threaded connection. Because the metal filter element 5 is made of titanium metal powder sintering, it is very difficult to be welded into one body with an ordinary upper connecting sleeve 9. Therefore, there is an internal thread in the upper connecting sleeve 9, and there is an external thread on the filter nozzle 11 of the metal filter element 5 that matches the internal thread. During installation, the metal filter element 5 passes through the lower connecting sleeve 7 and the partition hole 6 and is located in the separation chamber 3 until the upper chuck 10 abuts against the lower chuck 8, and then the upper chuck 10 and the lower chuck 8 are fixed and locked by the clamp to complete the assembly of the metal filter element 5. The above structure is simple, easy to assemble, and the disassembly process is the opposite of the assembly process, so it will not be described in detail.

[0029] As shown in the figure, the clamp includes a first half snap ring 12 and a second half snap ring 13 hinged to the first half snap ring 12. Both the first half snap ring 12 and the second half snap ring 13 are provided with clamping grooves. The edges of the upper chuck 10 and the lower chuck 8 are located in the clamping grooves, so that the clamping grooves simultaneously wrap the edges of the upper chuck 10 and the lower chuck 8. The first half snap ring 12 and the second half snap ring 13 are locked by screws. The ends of the first half snap ring 12 and the second half snap ring 13 are provided with locking plates, and there are locking holes on the locking plates. The screw rod passes through the locking holes and can be locked with the nut to lock the clamp. As a further structure, guiding inclined surfaces are provided at the edges of the upper chuck 10 and the lower chuck 8, and the clamping groove is a V-shaped groove. In this way, the edges of the upper chuck 10 and the lower chuck 8 are thinner, and the notch of the clamping groove is very wide. When installing, the clamping groove can easily be clamped on the edges of the upper chuck 10 and the lower chuck 8. Moreover, because of the inclined surface fit, when the first half snap ring 12 and the second half snap ring 13 are locked with each other through the screw rod, the upper chuck 10 and the lower chuck 8 can be closely attached to each other, making it more firm.

[0030] As shown in the figure, a plurality of spray pipes 15 are provided in the air outlet cavity 4. A plurality of spray holes (not shown in the figure) are provided on the spray pipes 15, and the spray holes face the filter element openings on the filter tip 11. The spray holes can spray compressed gas into the corresponding metal filter element 5. In this application, there is also an upper retaining ring 17 on the upper chuck 10. When the spray holes can spray compressed gas into the corresponding metal filter element 5, the upper retaining ring 17 can prevent the compressed gas from diffusing, so as to better utilize the compressed gas to clean the metal filter element 5. The spray pipes 15 are communicated with an external compressed gas source, which is a gas storage tank 16. The gas storage tank 16 is fixed outside the separation barrel 1 through a bracket. When the micropores on the metal filter element 5 are blocked by powder, the blocked powder can be blown off from the metal filter element 5 by spraying compressed gas into the metal filter element 5, so as to restore the filtering function of the metal filter element 5.

[0031] The above has introduced in detail a gas-solid separation device provided by an embodiment of the present invention. Specific examples are used in this article to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
