When the bottom butt of frame portion 31 in the bottom of first spout 8, torsional spring 12 resumes natural state this moment, and under torsional spring 12's reset effect, joint piece 11 rotates towards stopper 10's direction for the top of joint piece 11's butt portion 112 is contradicted with the bottom of stopper 10, makes coarse strainer 3 stable installation in box 1.

Referring to fig. 4 and 5, in order to conveniently take out the coarse filter 3 and the fine filter 4 at the same time, the sewage treatment apparatus is provided with a connection assembly including a first fixing block 13, a second fixing block 14, and a chain 15. The first fixing block 13 includes a first sub-block 131 and a second sub-block 132, and the first sub-block 131 and the second sub-block 132 are both horizontally disposed. The top of the first sub-block 131 is fixedly connected with one end of the chain 15, and the bottom of the first sub-block 131 is fixedly connected with the first sub-block 132 through a second connecting rod. The top of the frame portion 31 is provided with a first through groove 16 for the first fixing block 13 to rotate and clamp, the first through groove 16 comprises a first plug-in sub groove 161 and a first clamp sub groove 162 which are communicated with each other, the top of the first plug-in sub groove 161 penetrates through the top of the frame portion 31, the bottom of the first plug-in sub groove 161 is communicated with the top of the first clamp sub groove 162, and the maximum width of the bottom opening of the first plug-in sub groove 161 is smaller than the maximum width of the top opening of the first clamp sub groove 162. The first plug sub-slot 161 is used for the plug connection of the first sub-block 131 and the second connecting rod, and the first card sub-slot 162 is used for the rotational card connection of the first sub-block 131.

When the first fixing block 13 is rotatably connected to the first through groove 16 in a clamped manner, the top of the second sub-block 132 is connected to the top wall of the first clamping sub-groove 162 in an abutted manner, the second connecting rod is connected to the first connecting rod 161 in an inserted manner, and the bottom of the first sub-block 131 is connected to the top of the coarse strainer 3 in an abutted manner, so that the first fixing block 13 is fixedly connected to the coarse strainer 3. The second fixing block 14 comprises a third sub-block and a fourth sub-block, the top of the third sub-block is fixedly connected with the other end of the chain 15, and the bottom of the third sub-block is fixedly connected with the fourth sub-block through a third connecting rod. The top of the frame part of the fine filter screen 4 is provided with a second through groove for the fourth sub-block to rotate and clamp, the second through groove comprises a second inserting sub-groove and a second clamping sub-groove which are communicated with each other, and the second fixing block 14 is connected with the fine filter screen 4 through the second through groove in the same way as the first fixing block 13 is connected with the coarse filter screen 3 through the first through groove 16, which is not repeated herein.

It should be noted that, when coarse strainer 3 and fine strainer 4 were all installed at box 1, the length of chain 15 set up to be greater than the distance between coarse strainer 3 and the fine strainer 4 for first fixed block 13 and second fixed block 14 can correspond respectively and rotate the joint and lead to groove in first logical groove 16 and second.

In order to further remove the impurity in the sewage and deodorize sewage, the inside adsorber that is provided with of box 1, adsorber and outlet pipe 6 intercommunication setting, place in the adsorber and be used for adsorbing impurity and carry out deodorant active carbon particle to water. The sewage filtered by the coarse filter screen 3 and the fine filter screen 4 enters the adsorber from the water inlet end of the adsorber, the activated carbon particles adsorb impurities in the water and deodorize, and the treated water is discharged from the water outlet pipe 6 of the box body 1 through the water outlet end of the adsorber.

The implementation principle of rural sewage treatment equipment in the embodiment of the application is as follows: when carrying out sewage treatment, open the closing lid 7 at 1 top of box, insert and slide downwards coarse strainer 3 from the end of inserting of first spout 8, joint piece 11 is located the top of stopper 10, the staff makes joint piece 11 swing towards the direction that deviates from 1 inside wall of box, and the butt portion 112 that keeps joint piece 11 is vertical setting, and connecting portion 111 is the level setting, make be formed with the space of reserving for stopper 10 to pass through between butt portion 112 and the 1 inside wall of box, when the bottom of the frame portion 31 of coarse strainer 3 and the bottom butt of first spout 8, the staff releases joint piece 11, this moment under torsional spring 12's reset effect, joint piece 11 is contradicted with the bottom of stopper 10 until the top of butt portion 112 is rotated towards the direction of stopper 10, make coarse strainer 3 stable installation in box 1. The principle of installing the fine screen 4 is the same as that of installing the coarse screen 3, and thus, the explanation thereof is omitted.

After the coarse filter 3 and the fine filter 4 are installed in the box body 1, the closing cover 7 on the top of the box body 1 is covered. The sewage that will carry out the processing lets in box 1 from inlet tube 5 of box 1 in, filters the impurity in the sewage through filtering component, and the water after the filtration is discharged from the outlet pipe after the adsorption of adsorber.

When the coarse filter 3 and the fine filter 4 need to be taken out for cleaning, the closing cover 7 at the top of the box body 1 is opened, and the second sub block 132 is rotatably clamped in the first clamping sub groove 162 of the coarse filter 3, so that the first fixing block 13 is fixedly connected with the coarse filter 3; and the fourth sub block is rotatably clamped in a second clamping sub groove of the fine filter screen 4, so that the second fixing block 14 is fixedly connected with the fine filter screen 4. Upwards pulling chain 15, the relative stopper 10 of joint piece 11 upwards motion this moment, and at this in-process, ascending pulling force makes stopper 10 extrusion joint piece 11 butt portion 112 to make butt portion 112 along the direction upset that deviates from stopper 10, when butt portion 112 breaks away from the bottom of stopper 10, staff's accessible coupling assembling takes out coarse strainer 3 and fine filter screen 4. As the coarse strainer 3 is gradually moved upward, when the catching block 11 is disengaged from the stopper 10, the torsion spring 12 is reset and the catching block 11 is restored to the initial state.

When coarse strainer 3 needs to be taken out separately for cleaning, second sub-block 132 is rotationally clamped in first clamping sub-groove 162 of coarse strainer 3, so that first fixing block 13 is fixedly connected with coarse strainer 3, chain 15 is pulled upwards, coarse strainer 3 is taken out separately, and coarse strainer 3 is cleaned.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
