[0019] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0020] like Figure 1 and 2As shown, a hydrochloric acid double-layer filtering device includes a box body 1 and a connecting tube 2. There are two connecting tubes 2. The two connecting tubes 2 are symmetrically fixed and connected to the top of the box body 1. A guide structure 3 is symmetrically arranged inside the box body 1. The two guide structures 3 are respectively arranged corresponding to the two connecting tubes 2. A detachable filter plate 4 is arranged inside the guide structure 3. A liquid inlet structure 6 is arranged between the tops of the two guide structures 3, and a liquid outlet structure 5 is arranged between the bottoms of the two guide structures 3.

[0021] According to the above structure, when in use, hydrochloric acid is injected into the interior of the two guide structures 3 through the liquid inlet structure 6, and the hydrochloric acid is double-filtered through the two filter plates 4 respectively. When replacing the filter plate 4, the pipeline leading to the filter plate 4 to be replaced can be closed first, and the other filter plate 4 can perform the filtering work normally, avoiding the whole device from stopping when replacing the filter plate 4.

[0022] like Figure 2 and 3 As shown, the guide structure 3 includes a baffle structure 31 and a liquid guide tube 32. There are two baffle structures 31, and the two baffle structures 31 are symmetrically arranged. The filter plate 4 is arranged between the two baffle structures 31. The baffle structure 31 includes a baffle 311 fixedly connected to the inside of the box body 1, and one side of the baffle 311 is symmetrically fixedly connected to a conical cover 312, wherein a liquid guide tube 32 is arranged between the two conical covers 312, and the two conical covers 312 are connected through the liquid guide tube 32.

[0023] According to the above structure, when working, hydrochloric acid is introduced into one of the conical covers 312 through the liquid inlet structure 6. After the hydrochloric acid is filtered by the upper part of the filter plate 4, it flows through the liquid guide tube 32 and is filtered by the lower part of the filter plate 4 before entering the interior of the liquid outlet structure 5 and then being output. The hydrochloric acid has a better filtering effect after two layers of filtration.

[0024] like Figure 2 and 4 As shown, the filter plate 4 includes a "sun"-shaped frame 41, which is inserted between the two corresponding partitions 311, and the top and bottom of the "sun"-shaped frame 41 are fixedly connected with the filter layer 42, and the top of the "sun"-shaped frame 41 is fixedly connected with the top plate 43, and both sides of the top plate 43 are provided with equidistantly distributed through holes 44, which are inserted into the interior of the connecting tube 2, and bolts are arranged inside the through holes 44, and the top plate 43 is fixedly connected to the connecting tube 2 by bolts.

[0025] According to the above structure, during filtering, the hydrochloric acid is first filtered through the top filter layer 42 and then filtered through the bottom filter layer 42. When replacing the filter plate 4, the bolts inside the through hole 44 are removed, and the through hole 44 is pulled to extract the "sun"-shaped frame 41 from between the two partitions 311. During installation, the "sun"-shaped frame 41 is inserted between the two partitions 311, and the top plate 43 is reconnected to the connecting tube 2 with bolts.

[0026] like Figure 2-4 As shown, the liquid outlet structure 5 and the liquid inlet structure 6 have the same structure. The liquid inlet structure 6 includes a connecting pipe 61. The two ends of the connecting pipe 61 are respectively fixedly connected to one end of two conical covers 312. The middle part of the connecting pipe 61 is fixedly connected to a conduit 62. Battery valves 63 are fixedly installed on both sides of the connecting pipe 61.

[0027] According to the above structure, when the filter plate 4 is replaced, the corresponding two battery valves 63 distributed up and down are closed, so as to prevent hydrochloric acid from entering the corresponding guide structure 3 .

[0028] The working principle of the utility model is as follows: when in use, hydrochloric acid is injected into the interior of the two guide structures 3 through the liquid inlet structure 6, and the hydrochloric acid is double-filtered through the two filter plates 4 respectively. When replacing the filter plate 4, the pipeline leading to the filter plate 4 to be replaced can be closed first, and the other filter plate 4 can perform filtering work normally, so as to avoid the whole device stopping working when replacing the filter plate 4. When working, hydrochloric acid is introduced into one of the conical covers 312 through the liquid inlet structure 6, and the hydrochloric acid is filtered by the upper part of the filter plate 4, flows through the liquid guide pipe 32, and is filtered by the lower part of the filter plate 4, and then enters the interior of the liquid outlet structure 5. Then output, the hydrochloric acid has a better filtering effect after two layers of filtration. When filtering, the hydrochloric acid is first filtered through the top filter layer 42, and then filtered through the bottom filter layer 42. When replacing the filter plate 4, remove the bolts inside the through hole 44, pull the through hole 44 to extract the "sun" shaped frame 41 from between the two partitions 311. When installing, insert the "sun" shaped frame 41 between the two partitions 311, and re-connect the top plate 43 to the connecting tube 2 with bolts. When replacing the filter plate 4, close the corresponding two upper and lower distributed battery valves 63 to prevent hydrochloric acid from entering the corresponding guide structure 3.

[0029] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
