[0036] A first sliding hole 13, which is provided on the circumferential surface of the filter head body 1 and is connected to the mounting cylinder 7;

[0037] A second sliding hole 14, which is opened on the circumferential surface of the mounting tube 7 and is connected to the housing 4;

[0038] a first electric push rod 5, the first electric push rod 5 is fixedly connected to the housing 4, and an extended end of the first electric push rod 5 is fixedly connected to a first push plate 6; and

[0039] A driving assembly is arranged in the filter head body 1 .

[0040] In a specific embodiment of the present utility model, the shell 4 is fixed on the circumferential surface of the filter head body 1, and the storage component is arranged in the installation cylinder 7. The storage component is used to store the filter plate 2 to be replaced. The filter plate 2 in use is installed at one end of the filter head body 1. The filter plate 2 plays a filtering role in the denitrification filter tank. When the filter plate 2 in use needs to be replaced, the first electric push rod 5 is controlled to operate, and the extended end of the first electric push rod 5 drives the first push plate 6 to move downward. The first push plate 6 pushes a filter plate 2 in the installation cylinder 7 from the first sliding hole 13 to the filter head body 1, and then the second electric push rod 11 is operated, and the extended end of the second electric push rod 11 drives the second push plate 12 to push the filter plate 2 in use out of the two groups of clamping components. This process needs to overcome the elastic force of the second spring. The new filter plate 2 is clamped by the two groups of clamping components to complete the replacement of the filter plate 2; by using this device, when the filter head is used in the denitrification filter tank and needs to be replaced, the device automatically completes the replacement of the filter plate 2 without manual replacement.

[0041] For details, please refer to Figure 1-Figure 3 The storage assembly includes a first spring 8 and an extrusion plate 9. The first spring 8 is fixedly connected to an inner wall of one side of the mounting tube 7, and the extrusion plate 9 is fixedly connected to one end of the first spring 8.

[0042] In this embodiment: the first spring 8 in the storage assembly drives the extrusion plate 9 to squeeze the multiple filter plates 2 stored in the installation cylinder 7, so that the multiple filter plates 2 fit tightly.

[0043] For details, please refer to Figure 1-Figure 3 The driving assembly includes a mounting frame 10, a second electric push rod 11 and a second push plate 12. The mounting frame 10 is fixedly connected to the inner wall of the filter head body 1, the second electric push rod 11 is fixedly connected inside the mounting frame 10, and the second push plate 12 is fixedly connected to the extended end of the second electric push rod 11.

[0044] In this embodiment: when a new filter plate 2 moves into the filter head body 1, the second electric push rod 11 is controlled to operate, and the extended end of the second electric push rod 11 drives the second push plate 12 to push the filter plate 2 to the position where the filter plate 2 needs to be replaced, so as to replace the filter plate 2.

[0045] For details, please refer to Figure 1-Figure 3 Two groups of clamping assemblies are provided on one side of the filter head body 1, each group of clamping assemblies includes a clamping plate 3, a second spring and a hinge shaft, the clamping plate 3 is movably hinged to one end of the filter head body 1 through the hinge shaft, the second spring is installed in the hinge shaft, one end of the second spring is connected to the clamping plate 3, and the other end of the second spring is connected to the filter head body 1.

[0046] In this embodiment: the clamping plate 3 in the clamping assembly is kept parallel to the end surface of the filter head body 1 under the elastic force of the second spring. When the clamping plate 3 is rotated about the hinge axis, the elastic force of the second spring needs to be overcome. The second spring is a torque spring.

[0047] For details, please refer to Figure 1-Figure 3 The mounting cylinder 7 is provided with a plurality of filter plates 2, and a filter plate 2 is installed at one end of the filter head body 1.

[0048] In this embodiment, the filter plate 2 to be replaced is stored in the installation cylinder 7, and the filter plate 2 in use is clamped by two sets of clamping assemblies.

[0049] For details, please refer to Figure 1-Figure 3 , the elastic coefficients of the two second springs are both smaller than the elastic coefficient of the first spring 8.

[0050] In this embodiment: the elastic force of the second spring is smaller than the elastic force of the first spring 8 .

[0051] It should be noted that the specific types of the first electric push rod 5 and the second electric push rod 11 to be used are selected by relevant technicians familiar with the field, and the above-mentioned first electric push rod 5 and the second electric push rod 11 belong to the existing technology and will not be elaborated in this solution.

[0052] The working principle and use process of the utility model are as follows: when the device is in use, the filter head body 1 is first installed in the denitrification filter tank, and the liquid in the filter tank is filtered through the filter plate 2. When the filter plate 2 clamped by the two groups of clamping components needs to be replaced, the first electric push rod 5 is controlled to operate, and the extended end of the first electric push rod 5 drives the first push plate 6 to move downward. The first push plate 6 pushes a filter plate 2 stored in the installation cylinder 7 to move downward, and the filter plate 2 slides into the filter head body 1 through the first sliding hole 13. Then the second electric push rod 11 is controlled to operate, and the extended end of the second electric push rod 11 drives the second push plate 12 to move. The second push plate 12 pushes the new filter plate 2 to the position of the filter plate 2 that needs to be replaced, squeezes out the old filter plate 2, and the replacement is completed. By using the device, when the filter head is used in the denitrification filter tank and needs to be replaced, the device automatically completes the replacement of the filter plate 2 without manual replacement.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
