Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, and particularly relates to a novel screw conveyor. Background Art

[0002] The existing Chinese utility model patent with the application number 202122633900.8 discloses a screw conveyor for filtering garbage sewage. By arranging sewage holes on the bottom of the casing and the lining plate below the casing, the purpose of separating sewage is achieved. However, the structures of the bottom of the casing and the lining plate are fixed and cannot be adjusted. When sundries in the sewage pass through the sewage holes, there is a problem that the sundries get stuck in the sewage holes. If not cleaned in time, there will be problems of poor sewage separation effect and low efficiency. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a novel screw conveyor with good sewage solid-liquid separation effect and high efficiency in view of the deficiencies in the above background art.

[0004] To achieve the above purpose, the utility model provides a novel screw conveyor, which adopts the following technical solutions:

[0005] A novel screw conveyor includes a casing. A driving structure is arranged on one side of the casing and is connected to a screw conveyor shaft disposed in the casing. A notch is opened at the bottom of the casing, and a filter water tank is arranged below the notch. An inlet is arranged at the upper part of the casing, and an outlet is arranged at the lower part of the casing. A cylinder is arranged in the casing and is horizontally disposed between the inlet and the outlet. A plurality of filter holes are arranged on the cylinder. The screw conveyor shaft passes through the cylinder. The cylinder is rotatably connected to the casing. A fixing plate is also fixedly arranged in the casing. The fixing plate is in a C shape and is located directly below the inlet. Filter holes are also arranged on the fixing plate. One side of the fixing plate extends into the cylinder, and a baffle is arranged on the other side.

[0006] A further improvement of the novel screw conveyor of the utility model is that bearing seats are arranged on both side parts of the cylinder, and the bearing seats are connected to the casing. A ring of racks is arranged on the outer side of the cylinder. A motor is arranged on the lower end face of the upper part of the casing, and the motor is connected to a gear. The gear meshes with the racks for transmission.

[0007] A further improvement of the novel screw conveyor of the utility model is that a scraper is also slidably connected to the upper end face of the casing, and the sliding direction is the conveying direction of the screw conveyor shaft.

[0008] A further improvement of the novel screw conveyor of the utility model is that fixed scrapers are arranged on the front and rear side plates of the casing. The fixed scrapers are in a strip shape and are arranged along the length direction of the casing and are in contact with the outer wall of the cylinder.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] In the utility model, a cylinder is added inside the casing of the screw conveyor. While realizing the separation and filtration of sewage, the cylinder can also rotate, avoiding sundries being stuck in the filter holes for a long time and affecting the separation and filtration efficiency. On the other hand, a scraper is added to actively clean and prevent sundries from being stuck at the filter holes. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 is a schematic structural view of the utility model;

[0012] In the figure: 1 casing, 2 filter water tank, 3 feed inlet, 4 discharge outlet, 5 cylinder, 6 fixing plate, 7 bearing seat, 8 scraper. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0013] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0014] As Figure 1 shown, a new type of screw conveyor includes a casing 1. A driving structure is provided on one side of the casing, and the driving structure is connected to a screw conveyor shaft disposed inside the casing. A notch is opened at the bottom of the casing, and a filter water tank 2 is provided below the notch. A feed inlet 3 is provided on the upper right side of the casing, and a discharge outlet 4 is provided on the lower left side. The above structure is one of the conventional structures of the existing screw conveyor. Further, a cylinder 5 is provided inside the casing. The cylinder is horizontally disposed between the feed inlet and the discharge outlet. A plurality of filter holes are provided on the cylinder. The screw conveyor shaft passes through the cylinder and can realize the conveyance of materials inside the cylinder. The cylinder is rotatably connected to the casing. A fixing plate 6 is also fixedly provided inside the casing. The fixing plate is in a C shape and is located directly below the feed inlet. Filter holes are also provided on the fixing plate. One side of the fixing plate extends into the cylinder, and a baffle is provided on the other side. A slight gap is left between the part of the fixing plate extending into the cylinder and the cylinder, so as to ensure the conveyance of sundries in the sewage.

[0015] Further, bearing seats 7 are provided on both sides of the cylinder. The bearing seats are connected to the casing. A rack is provided on the outer side of the cylinder. A motor is provided on the lower end face of the upper part of the casing. The motor is connected to a gear, and the gear meshes with the rack for transmission.

[0016] Further, a scraper 8 is also slidably connected to the upper end face of the casing, and the sliding direction is the conveyance direction of the screw conveyor shaft. The sliding manner can be realized by a telescopic cylinder.

[0017] Further, fixed scrapers are provided on the front and rear side plates of the casing. The fixed scrapers are in a strip shape and are arranged along the length direction of the casing and are in contact with the outer wall of the cylinder.

[0018] The working principle of the present utility model is as follows: Sewage enters the casing and lies on the fixed plate from the feed inlet. Driven by the spiral conveying structure, sundries will move forward, and the sewage liquid will be discharged from the filter holes. The sundries and sewage will enter the cylinder, and at the same time, the filtration and separation of the sewage will be carried out. After working for a period of time, rotate the cylinder and start the scraper to clean the upper part of the bottom cylinder under the scraping of the scraper, preventing sundries from getting stuck in the filter holes and ensuring the efficiency of solid-liquid separation in the sewage.
