However, due to factors such as equipment cost and floor space, the feasibility is poor. Summary of the invention

[0037] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0039] Example 1

[0040] like Figure 1 As shown, this embodiment provides an electrocoagulation plate, comprising:

[0041] Plate 1;

[0042] A plurality of first tooth plates 2 are all fixed on a plate surface of the plate body 1, the first tooth plates 2 are perpendicular to the plate body 1, and all the first tooth plates 2 are parallel to each other;

[0043] A plurality of second tooth plates 3 are all fixed on the other plate surface of the plate body 1 . The second tooth plates 3 are parallel to the first tooth plates 2 and are staggered in distribution.

[0044] The electric flocculation plate of this embodiment increases the contact area between the sewage and the electric flocculation plate by arranging tooth plates on the two plate surfaces of the plate body 1, thereby improving the electric flocculation effect. Compared with the solution in the prior art that increases the contact area between the sewage and the electric flocculation plate by increasing the area of ​​the electric flocculation plate, the equipment cost is lower, and the decoupling of the area of ​​the electric flocculation plate and the area occupied by the device is achieved, which is more feasible. In addition, by arranging the tooth plates, vortices can be formed between the tooth plates, further improving the electric flocculation effect.

[0045] It should be understood that the plate body 1 , the first tooth plate 2 and the second tooth plate 3 are all made of conductive materials such as aluminum and iron to function as electrode plates.

[0046] It should be understood that: the first tooth plate 2 and the second tooth plate 3 are essentially flat plate structures. Because the multiple tooth plates form a tooth shape, they are named tooth plates here.

[0047] As an improved structure of the tooth plate, the lengths of the first tooth plate 2 and the second tooth plate 3 protruding from the plate body 1 are adjustable. For those skilled in the art, there are many solutions to achieve the adjustable length, such as the tooth plate being a telescopic plate, or the tooth plate being slidably mounted on the plate body 1, or the tooth plate being an assembled structure and the length adjustment is achieved by the number of assembled units.

[0048] Here is a preferred adjustable structure of the tooth plate, such as Figure 2 As shown, the first tooth plate 2 and / or the second tooth plate 3 includes:

[0049] A plate frame 4, which is fixed on the plate body 1;

[0050] A sliding plate 5 is inserted and slidably disposed in the plate frame 4 and its sliding direction is perpendicular to the plate body 1. The sliding plate 5 is sealed and connected to the plate frame 4.

[0051] The locking structure is suitable for fixing the sliding plate 5 on the plate frame 4.

[0052] The fixing method of the plate frame 4 on the plate body 1 is not limited, and it can be integrally formed or fixed by welding or other methods.

[0053] It is easy to understand that the sealing connection between the sliding plate 5 and the plate frame 4 can be achieved by using common structures such as sealing rings and sealing pads. Specifically, a sealing structure such as a sealing ring can be fixed to the inner wall of the plate frame 4 away from the end of the plate body 1, and the sliding plate 5 contacts the sealing structure to achieve sealing.

[0054] The specific structure of the above locking structure is not limited, and can be a bolt structure, that is, the bolts are screwed on the plate frame 4 so that the bolt heads abut against the sliding plate 5 to achieve locking; it can also be multiple sets of buckles; it can also be multiple sets of magnetic suction.

[0055] like Figure 2 and Figure 3 As shown, a preferred locking structure is provided here, a plurality of groups of positioning holes 6 are provided on the plate frame 4, the plurality of groups of positioning holes 6 are distributed in a direction perpendicular to the plate body 1, each group of positioning holes 6 includes at least two positioning holes 6, and when each group of positioning holes 6 is provided with a plurality of positioning holes 6, the distribution direction of all positioning holes 6 is parallel to the plate body 1, the locking structure is a telescopic pin 7 vertically mounted on the sliding plate 5, the telescopic pin 7 is provided with at least one pair and the number of pairs of telescopic pins 7 is equal to the number of each group of positioning holes 6, each pair of telescopic pins 7 is symmetrically mounted on the two plate surfaces of the sliding plate 5, each pair of telescopic pins 7 is inserted into the same positioning hole 6 and all pairs of telescopic pins 7 are respectively inserted into all positioning holes 6 in the same group to fix the sliding plate 5 relative to the plate frame 4.

[0056] The number of the positioning holes 6 is not limited. Figure 3 The positioning holes 6 shown in the figure are provided with two groups, which can make the locking force more uniform and the locking more secure; of course, the positioning holes 6 can be provided in one group or three groups. The number of the positioning holes 6 in each group is also not limited, as long as it is greater than or equal to two, for example Figure 3 Three positioning holes 6 are shown in each group.

[0057] The telescopic pin 7 is a commonly used structure in the art, generally consisting of a telescopic tube and a spring, and the spring provides the telescopic tube with a reset capability.

[0058] As an improved structure of the telescopic pin 7, the outer end of the telescopic pin 7 is set to a truncated cone structure with a decreasing diameter toward the outside, and the axial length of the truncated cone structure is greater than the wall thickness of the plate frame 4. When the telescopic pin 7 is pressed, it only needs to be retracted to be flush with the outer surface of the plate frame 4, and then the sliding plate 5 can be easily slid relative to the plate frame 4 by using the guiding effect of the side wall of the truncated cone structure, without retracting it into the plate frame 4, which further improves the convenience of operation.

[0059] Furthermore, the inner wall of the plate frame 4 is provided with a slide groove 8 along the sliding track of the telescopic pin 7. The slide groove 8 can guide the movement of the sliding plate 5, avoiding the difficulty of aligning the telescopic pin 7 with the positioning hole 6 due to the displacement of the sliding plate 5.

[0060] Furthermore, a compression spring is connected to the portion of the sliding plate 5 disposed in the plate frame 4 , and the compression spring is suitable for driving the sliding plate 5 to slide in a direction away from the plate body 1 .

[0061] Example 2

[0062] like Figure 4 As shown, this embodiment provides an electric flocculator, comprising:

[0063] Tank body 9;

[0064] At least two of the aforementioned electro-flocculation plates are fixed in the tank body 9 , and the plates 1 of all the electro-flocculation plates are parallel, and the first tooth plates 2 are arranged along the depth direction of the tank body 9 .

[0065] It should be understood that: the electrocoagulator is also provided with a power supply group, which energizes the electrocoagulation plates to form electrode plates. Specifically, the polarities of adjacent electrocoagulation plates are opposite.

[0066] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present invention.
