[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A primary wastewater filtration box includes a filtration box body, a support mesh fixedly installed on the inner side of the filtration box body, a filter screen covered on the support mesh, a fixing frame fixedly installed on the side of the filter screen, needles spaced apart on the top of the support mesh, the needles passing through the top of the filter screen and inserted into the fixing frame for fixation, a guide pipe provided on one side of the bottom of the filtration box body, and a groove opening opened on the top of the filtration box body.

[0006] As a further description of the above technical solution:

[0007] The support mesh has a concave-downward structure.

[0008] As a further description of the above technical solution:

[0009] The top edge of the support net is the same size as the fixed frame.

[0010] As a further description of the above technical solution:

[0011] The fixing frame is a flexible rubber strip.

[0012] As a further description of the above technical solution:

[0013] The guide tube is a flexible and stretchable tube.

[0014] As a further description of the above technical solution:

[0015] The guide tube and the groove opening are positioned correspondingly.

[0016] Compared with the prior art, the present invention provides a primary wastewater filtration box, which has the following beneficial effects:

[0017] 1. In this utility model, a support net is set inside the filter box to support the shaped filter screen, and the filter screen is used to filter sewage. The structure is simple, can be stacked and placed one on top of the other, is convenient to use, and has low cost; 2. In this utility model, the filter screen is easy to remove, and the residue left after filtration can be caught and removed. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example:

[0024] Please see Figures 1-2 This utility model provides a primary wastewater filtration box, including a filtration box body 1, a support net 2 fixedly installed on the inner side of the filtration box body 1, a filter mesh 3 covered on the support net 2, a fixing frame 4 fixedly installed on the side of the filter mesh 3, needles 5 spaced apart on the top of the support net 2, the needles 5 passing through the top of the filter mesh 3 and inserted into the fixing frame 4 for fixation, a guide pipe 6 provided on one side of the bottom of the filtration box body 1, and a groove 7 opened on the top of the filtration box body 1.

[0025] Specifically, such as Figure 1 As shown, the support mesh 2 has a concave-downward structure, a large filtration surface, and facilitates the formation of a pocket structure by the filter mesh 3, making it easy to remove waste residue.

[0026] Specifically, the top edge of the support net 2 is the same size as the fixed frame 4, making it easy to use.

[0027] Specifically, the fixed frame 4 is made of flexible rubber strips, which are easy to remove and place.

[0028] Specifically, the guide tube 6 is a flexible and stretchable tube, which is easy to adjust.

[0029] Specifically, such as Figure 2 As shown, the guide pipe 6 and the groove opening 7 are positioned correspondingly, facilitating water flow between the upper and lower filter boxes.

[0030] Working principle:

[0031] When in use, the filter screen 3 is laid on the support net 2, and the needle 5 is inserted through the filter screen 3 into the fixed frame 4 to fix the filter screen 3. The sewage enters the filter box 1, sinks and is filtered by the filter screen 3, and falls to the bottom of the filter box 1. The filtered sewage is discharged from the position of the guide pipe 6. The guide pipe 6 can be inserted into the secondary filter box with the groove 7 below for further sewage treatment.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
