Detailed Description

The technical solutions in the implementation of the present invention will be clear from the following description and accompanying drawings, and the described embodiments are only some embodiments, not all embodiments, of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1, embodiment 1 of the utility model provides a domestic sewage preliminary filtration device, including installing chain conveyor 2 in ditch 1, chain conveyor 2 is including installing frame 4 on ditch 1 and can the circulation pivoted conveyer belt, is provided with the drainage hole on the conveyer belt, installs motor 6 in the frame 4, and motor 6 drive conveyer belt circulation rotates to make the conveyer belt can filter out the rubbish of aquatic and carry the rubbish fill 5 at rear, still be provided with curb plate 21 in the frame 4 of conveyer belt both sides, prevent that rubbish from rolling outside the ditch 1 from the both sides of conveyer belt.

Frame 4 top is provided with conveyer belt complex extrusion mechanism, a plurality of even baffle 3 in interval of fixed mounting on the conveyer belt, extrusion mechanism includes stripper plate 41 and guiding mechanism, stripper plate 41 articulates in frame 4, guiding mechanism is including setting up spring 42 between frame 4 and stripper plate 41, when conveyer belt circulation rotates like this, baffle 3 can block rubbish from the bottom, when baffle 3 is more and more near apart from stripper plate 41, under spring 42's effect, spring 42 can withstand stripper plate 41 and let

stripper plate

41 and 3 cooperation extrusion rubbish of baffle, thereby extrude the moisture in the rubbish, extruded moisture can be followed and fallen into ditch 1 and be retrieved in the drainage hole. When the conveyer belt continues to rotate, the baffle 3 finally enables the extrusion plate 41 to overcome the spring 42 so that the extrusion plate 41 can rotate, thereby gradually separating from the baffle 3, and in the process, the baffle 3 can also play a role in scraping off the garbage residue on the surface of the extrusion plate 41. When the baffle 3 is completely disengaged from the pressing plate 41, the conveyor belt can continue to convey the garbage until the garbage is conveyed into the garbage hopper 5.

The utility model discloses embodiment 1's technical scheme has realized carrying out the purpose of wringing to the rubbish that filters out to further improved and filtered the effect of retrieving to domestic sewage, still alleviateed the rubbish weight of filtering out simultaneously, reduced subsequent transportation treatment cost.

Above-mentioned technical scheme still has some not enoughly when getting above-mentioned effect, because stripper plate 41 directly articulates in frame 4, when this leads to baffle 3 and stripper plate 41 cooperation extrusion rubbish, is not parallel relation between baffle 3 and the stripper plate 41, has certain contained angle, has influenced the extrusion effect, consequently the utility model discloses further proposed the improvement scheme as embodiment 2 on embodiment 1's basis.

As shown in fig. 2 to 6, the embodiment 2 of the present invention improves the installation structure of the squeezing plate 41 and the guiding mechanism on the basis of the embodiment 1, specifically, the guiding mechanism includes a first guiding post 31 fixedly installed on the frame 4 and a spring 42 sleeved on the first guiding post 31, the sliding seat 32 is slidably installed on the first guiding post 31 at one end of the spring 42 away from the frame 4, the first guiding post 31 is parallel to the conveying belt, the squeezing plate 41 is hinged at the bottom of the sliding seat 32, meanwhile, a limiting mechanism capable of limiting the rotation of the extrusion plate 41 is arranged on the sliding seat 32, so that when the baffle plate 3 is matched with the extrusion plate 41 for extrusion, the extrusion plate 41 compresses the spring 42 along with the sliding seat 32, since the sliding base 32 moves along the first guiding column 31, the pressing plate 41 can maintain a parallel relationship with the baffle 3, so that the pressing plate 41 and the baffle 3 can better press the garbage in the middle.

Specifically, the limiting mechanism comprises a guide hole 33 formed in the sliding seat 32, a limiting plate 34 is inserted in the guide hole 33 in a sliding manner, one end of the limiting plate 34 can penetrate through the guide hole 33 and extend to one side of the extrusion plate 41, so that when the baffle plate 3 is extruded to the extrusion plate 41, the extrusion plate 41 can be limited by the limiting plate 34 and cannot rotate, the extrusion plate 41 can drive the sliding seat 32 to move on the first guide post 31 and extrude the spring 42, and parallel extrusion between the extrusion plate 41 and the baffle plate 3 is achieved.

Meanwhile, the sliding seat 32 is further provided with a bracket 321, the top of the limit plate 34 is provided with a second guide post 35, the second guide post 35 penetrates through the bracket 321 and is in sliding fit with the bracket 321, and the spring 42 is sleeved on the second guide post 35 between the bracket 321 and the limit plate 34, so that the limit plate 34 can be maintained at one side of the extrusion plate 41 under the action of the spring 42, and the limit function is kept. When the pressing plate 41 and the baffle 3 press the garbage to a certain degree, the pressing plate 41 and the baffle 3 are always required to be separated, otherwise, the pressing plate 41 can block the circular rotation of the conveying belt.

In order to achieve the purpose, a lifting block 37 with a slope is arranged on the rack 4, and a lifting hole 36 matched with the lifting block 37 is formed in the limit plate 34, so that when the extrusion plate 41 is pushed to a certain position by the baffle 3, the lifting block 37 can be matched with the lifting hole 36, the limit plate 34 moves in the guide hole 33, the limit plate 34 can compress a spring 42 sleeved on the guide post II 35 and gradually breaks away from contact with the extrusion plate 41, the limit effect on the limit plate 34 is eliminated, at the moment, the baffle 3 can push the extrusion plate 41 to rotate, the extrusion plate 41 is gradually separated from the baffle 3, the baffle 3 and the conveying belt continue conveying the garbage, and the extruded garbage is conveyed into the garbage hopper 5.

To sum up, the utility model discloses embodiment 2 has further improved the extrusion effect to rubbish, and moisture is extruded more thoroughly.

During the specific use, motor 6 drive conveyer belt circulation rotates, and rivers are flowed through from ditch 1, and rubbish is by the separation of conveyer belt and carried the eminence by the conveyer belt, and when baffle 3 was more and more close stripper plate 41, rubbish between baffle 3 and the stripper plate 41 just can receive the extrusion to extrude the moisture in the rubbish, when baffle 3 when the conveyer belt continues to carry, baffle 3 and stripper plate 41 break away from gradually, and finally the conveyer belt is carried rubbish in fighting 5.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
