Description

Technical Field

[0001] The utility model provides a slaughterhouse sewage treatment device for a slaughterhouse, belonging to the technical field of sewage treatment. Background Art

[0002] Slaughterhouse wastewater comes from pen washing, rinsing, slaughtering and other factory floor washing, scalding, dissection, food processing, oil washing, etc. The wastewater mainly contains oil, blood, grease, minced meat, bone residue, hair and feces, etc. The wastewater is brown-red and has a strong fishy smell. Slaughterhouse wastewater has the characteristics of large water volume, uneven drainage, high concentration, many impurities and suspended solids, and good biodegradability. At present, in order to filter the solid waste in slaughterhouse wastewater and disinfect the liquid wastewater, slaughterhouse wastewater treatment equipment is usually required.

[0003] The existing treatment devices can basically meet the slaughterhouse's needs for slaughterhouse wastewater treatment. The existing slaughterhouse wastewater treatment equipment includes a filter box, a connecting pipe and a treatment box. The generated sewage is introduced into the working chamber from the water inlet pipe, and the solid impurities in the sewage are filtered through a filter net. The filter net is vibrated by a vibration component to avoid clogging the filter net. The filtered sewage enters the treatment box through a connecting pipe, and then disinfectant is added to the treatment box. The mixture is stirred and mixed by a stirring component to disinfect the sewage in the chamber and then discharged from the drain pipe.

[0004] Based on the above structure and the prior art, it is found that since a special drive motor is often required when the filter screen is vibrated by the vibration component, and a special drive motor is also required when the stirring component is stirred and mixed, it inevitably leads to an increase in comprehensive costs, and the resource utilization rate needs to be improved; and when the filter screen is filtering slaughter sewage, the filter screen is directly impacted by the slaughter sewage, causing the solid waste in the slaughter sewage, especially sharp waste such as broken bones, to directly collide with the filter screen, which is easy to cause damage to the filter screen after long-term use, reducing the service life. Based on this, the utility model provides a slaughter sewage treatment device for a slaughterhouse. Utility Model Content

[0005] The technical problems solved by the utility model are: motors are needed for filter vibration and sewage stirring, which increases the overall cost and requires improvement in resource utilization; the filter is directly impacted by slaughterhouse sewage, causing solid waste inside to directly collide with the filter, which can easily damage the filter after long-term use, reducing its service life.

[0006] In order to solve the technical problem, the technical solution provided by the utility model is: a slaughterhouse wastewater treatment device for a slaughterhouse, comprising a treatment box and a collecting box arranged on one side of the treatment box, the treatment box is provided with an inclined filter screen, the treatment box is provided with a filter water wheel placed above the filter screen, and a stirring assembly placed below the filter screen, a camshaft is provided at the bottom of the inclined upper end of the filter screen, the treatment box is provided with a driving assembly for driving the stirring assembly and the camshaft to rotate simultaneously, the filter water wheel comprises a wheel body, a wheel axle fixedly arranged in the wheel body, and a plurality of partition plates arranged on the inner wheel wall of the wheel body.

[0007] Furthermore, the stirring assembly includes a rotating rod, and a plurality of stirring blades are equidistantly arranged on the rotating rod.

[0008] Furthermore, the camshaft, the wheel axle and one end of the rotating rod are rotatably connected to an inner wall of the processing box, and the driving assembly includes pulleys placed on the outside of the processing box and distributed in a triangular shape. The other ends of the camshaft, the wheel axle and the rotating rod pass through the other side wall of the processing box and are fixedly connected to the end of the pulley, and matching belts are provided between the pulleys.

[0009] Furthermore, an inlet is provided on the top of the treatment box, an outlet is provided on the bottom wall of one side of the treatment box, a control valve is provided on the outlet, and a treatment agent feed hopper is provided on the side wall of the treatment box under the filter screen.

[0010] Furthermore, the side wall of the processing box is connected to the top of the collecting box by a debris discharge port, and the inner bottom wall of the debris discharge port close to the mouth of the processing box is provided with a rotating shaft rotatably connected to the bottom of the oblique lower end of the filter screen.

[0011] Furthermore, a plurality of filter holes are provided on the circumference of the inner wheel wall of the wheel body.

[0012] Beneficial effects of the utility model:

[0013] 1. Through the driving component, the rotation of the filter water wheel can make the camshaft and the rotating rod rotate, and the vibration of the filter screen and the stirring of the sewage can be realized without using a motor, thereby reducing the overall cost and improving the resource utilization rate;

[0014] 2. Solid waste will be retained in the cavity formed between the wheel body and the partition plate through the filter wheel. When it accumulates to a certain weight, it will drive the filter wheel to rotate, and then the solid waste in the cavity will fall onto the filter net along with the rotation of the filter wheel. This can prevent solid waste, especially sharp waste such as broken bones, from directly colliding with the filter net, so as to avoid damage to the filter net after long-term use and extend its service life.

[0027] Principle of the utility model

[0028] When in use, after the slaughter sewage with solid waste impurities enters the treatment box 1 through the inlet 15, it will first fall onto the filter water wheel 4. Under the action of the filter hole 20, the sewage will flow downward through the filter hole 20, and the solid waste will be retained in the compartment formed between the wheel body 8 and the partition plate 10. When it accumulates to a certain weight, it will drive the filter water wheel 4 to rotate, and then the solid waste in the compartment will fall onto the filter screen 3 along the rotation of the filter water wheel 4, which can prevent the solid waste, especially the sharp waste such as broken bones, from directly colliding with the filter screen 3, so as to avoid the filter screen being damaged after long-term use, thereby extending the service life;

[0029] Through the driving component 7, the rotation of the filter water wheel 4 can cause the wheel shaft 9 to rotate, which in turn drives the pulley 13 connected to the wheel shaft 9 to rotate. Under the action of the belt 14, the remaining pulleys 13 are driven to rotate, and the camshaft 6 and the rotating rod 11 connected to the remaining pulleys 13 are driven to rotate. The vibration of the filter screen and the stirring of the sewage can be achieved without using a motor, thereby reducing the overall cost and improving resource utilization.

[0030] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
