[0020] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the present invention, the following is a detailed description in conjunction with the accompanying drawings and preferred embodiments.

[0021] The utility model provides a concentration and filtering device and a reactor having the same. The concentration and filtering device can be directly arranged in the reactor and can better concentrate and filter the slurry in the reactor.

[0022] Figure 1 The figure is a schematic diagram of the structure of the concentration and filtration device provided in the embodiment of the utility model arranged in the reaction kettle. Figure 2 The figure shows the axial structural diagram of the support of the concentration and filtration device. Figure 3 Shown Figure 2 Schematic diagram of the structure of the middle bracket from above. Figure 4 The figure shows the structure of the filter element of the concentration and filtration device. Figures 1 to 4 As shown, the concentration and filtration device provided by the utility model includes a solid-liquid separation mechanism 10. The solid-liquid separation mechanism 10 is used to be arranged on the reactor 30, specifically, it is arranged on the top of the reactor 30. It includes a bracket 31, a connecting pipe 32 and a filter element 33 for installation on the reactor 30. The connecting pipe 32 includes a first connecting pipe 321 and a second connecting pipe 322 that are interconnected. The first connecting pipe 321 and the second connecting pipe 322 are respectively arranged on both sides of the bracket 31. When the bracket 31 is fixed on the reactor 30, the first connecting pipe 321 extends out of the reactor 30, and the second connecting pipe 322 is used to extend into the reactor 30. The filter element 33 is connected to the second connecting pipe 322. The first connecting pipe 321 is connected to the pump body 20

[0023] When the concentration and filtration device provided in this embodiment is used to filter and concentrate the slurry in the reactor 30, the support 31 can be fixed to the top of the reactor 30, and the second connecting pipe 322 can be extended into the reactor 30, and then the filter element 33 can be fixed to the end of the second connecting pipe 322 away from the support 31, and the filter element 33 can be completely immersed in the slurry. When in use, a negative pressure is formed in the filter element 33, and the solid and liquid in the slurry are separated by the negative pressure, and the liquid enters the filter element 33 and is discharged from the reactor 30 through the first connecting pipe 321 and the second connecting pipe 322, so that the solid is retained in the reactor 30 while the liquid is discharged from the reactor 30.

[0024] In this embodiment, since the first connecting pipe 321 and the second connecting pipe 322 are respectively arranged on both sides of the bracket 31, the first connecting pipe 321 can be connected to the pump body 20, and the second connecting pipe 322 can extend into the reactor 30, which makes it easier for the filter element 33 to be completely immersed in the slurry during installation, so as to prevent the filter element 33 from being sucked in air due to contact with the air. That is, the concentration and filtration device can be directly arranged in the reactor 30, and can better concentrate and filter the slurry in the reactor 30.

[0025] Furthermore, in this embodiment, the first connecting tube 321 and the second connecting tube 322 can be directly fixed on the bracket 31 and communicate with each other.

[0026] In other embodiments, the first connecting tube 321 and the second connecting tube 322 may be an integrated structure and directly fixed on the bracket 31 .

[0027] Furthermore, the concentration and filtration device also includes a pump body 20 connected to the first connecting pipe 321 to form a negative pressure in the filter element 33. A quick-connect plug (not shown) is provided at one end of the first connecting pipe 321 away from the bracket 31 to facilitate connection with the pipeline on the pump body 20.

[0028] The second connecting tube 322 extends in the vertical direction and has a threaded opening 3221 for connection formed at the end away from the bracket 31. The filter element 33 has a first connecting portion 331 formed on the end facing the second connecting tube 322. The filter element 33 is threadedly engaged with the second connecting tube 322 through the first connecting portion 331 and is fixed to the second connecting tube 322 in the vertical direction.

[0029] The filter element 33 can be alloy sintered felt or non-metal sintered felt.

[0030] In this embodiment, a plurality of filter elements 33 are provided on the solid-liquid separation mechanism 10, and each filter element 33 can be connected to a connecting pipe 32. The diameter of each filter element 33 is 10-160 mm, preferably 10-50 mm. The distance between two filter elements 33 (i.e. Figure 3 a) in the figure is 1 / 6d-d, and d is the diameter of the filter element 33. It should be explained that the two filter elements 33 refer to one filter element 33 and another filter element 33 that is closest to it, and the distance between the two filter elements 33 refers to the shortest straight-line distance between the peripheries of the two filter elements 33.

[0031] By limiting the length and diameter of the filter element 33 , during solid-liquid separation, the liquid in the slurry can be efficiently sucked out, while solids can be prevented from being clogged between the two filter elements 33 and reducing the filtering performance of the filter element 33 .

[0032] A second connection portion 332 is formed on one end of the filter element 33 away from the bracket 31. The solid-liquid separation mechanism 10 further includes a fixing plate 34. The filter element 33 is connected to the fixing plate 34 via the second connection portion 332. The fixing plate 34 is used to be fixed to the reactor 30. Through the above arrangement, the filter element 33 can be prevented from shaking under the action of the flow field in the reactor 30, thereby reducing the filtering effect.

[0033] Furthermore, the second connecting portion 332 can be a screw arranged at the end of the filter element 33, and a through hole (not shown in the figure) is provided on the fixing plate 34. The second connecting portion 332 extends into the through hole of the fixing plate 34, and the nut 341 is connected to the second connecting portion 332 from the side of the fixing plate 34 away from the filter element 33 to fix the filter element 33 to the fixing plate 34.

[0034] For further information, please refer to Figure 2 A plurality of buckle portions 311 are formed on the bracket 31 . When the bracket 31 is disposed on the reactor 30 , the buckle portions 311 are used to be combined with clips (not shown) on the reactor 30 to fix the bracket 31 .

[0035] The utility model further provides a reactor 30, which includes the above-mentioned concentration and filtration device. The bracket 31 of the concentration and filtration device is fixed to the top of the reactor 30, and the filter element 33 extends into the reactor 30 along the vertical direction.

[0036] In summary, the concentration and filtration device provided by the present invention can be directly fixed in the reaction kettle 30, and directly filter the slurry in the reaction kettle 30 to discharge the liquid in the slurry, thereby reducing costs and improving the yield of the product.

Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention.
