Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage concentration separation tank. Background Art

[0002] Biogas fermentation, also known as anaerobic digestion, refers to the process in which organic matter (such as human and livestock feces, straw, weeds, etc.) is decomposed and metabolized by various microorganisms under certain moisture, temperature and anaerobic conditions to eventually form a combustible mixed gas such as methane and carbon dioxide. The biogas fermentation system is based on the principle of biogas fermentation, with energy production as the goal, and ultimately achieves the comprehensive utilization of biogas, biogas liquid and biogas residue.

[0003] When treating sewage, it is necessary to first introduce the sewage into a pretreatment tank for pretreatment, and then inject it into an anaerobic fermentation tank for reaction and fermentation. The existing pretreatment tank has the following defects in actual use: it is impossible to separate the concentration of the introduced sewage, and most of the microorganisms and organic matter involved in anaerobic fermentation exist in the solid matter in the sewage. When feeding, the traditional pretreatment will inject the sewage with a higher concentration (and more solids) and a large amount of sewage with a lower concentration (and liquid sewage) into the fermentation tank together, resulting in fewer components actually participating in the fermentation reaction in the anaerobic tank, which increases the processing load of the fermentation tank and reduces the fermentation efficiency. Utility Model Content

[0004] In view of the above situation, in order to make up for the deficiencies of the prior art, the purpose of the utility model is to provide a sewage concentration separation tank, which effectively solves the problem that the existing pretreatment tank is unable to perform concentration separation on the sewage.

[0005] The technical solution is that the utility model comprises a rectangular pool body, a rectangular separation plate which can be moved forward and backward is arranged on the rear side of the pool body, a plurality of rectangular filter slots which are evenly distributed in the up and down directions are arranged on the separation plate, a filter screen is arranged in the filter slot, a rectangular shielding plate which can be moved up and down is arranged at the front end of the separation plate, the shielding plate can shield the filter slot, a plurality of connecting slots which correspond one to one with the filter slots and can be connected with the filter slots are arranged on the shielding plate, a feed pipe is arranged at the left end of the pool body, and discharge pipes are respectively arranged at the front and rear sides of the right end of the pool body.

[0006] Compared with the prior art, the utility model has the following beneficial effects: it can realize concentration separation of sewage liquid in the tank body, isolate sewage liquid with higher concentration at the front side of the tank body, isolate sewage liquid with lower concentration at the back side of the tank body, directly input sewage liquid with lower concentration into the biogas pool for storage, reduce the treatment load of the anaerobic fermentation tank, and improve the efficiency of manure treatment and anaerobic fermentation.

[0016] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0017] Depend on Figures 1 to 5It is given, including a rectangular pool body 1, a rectangular separation plate 2 which can be moved forward and backward is provided on the rear side of the pool body 1, a plurality of rectangular filter slots 3 which are evenly distributed in the up and down directions are provided on the separation plate 2, a filter screen 4 is provided in the filter slot 3, a rectangular shielding plate 5 which can be moved up and down is provided at the front end of the separation plate 2, the shielding plate 5 can shield the filter slot 3, a plurality of connecting slots 6 which correspond to the filter slots 3 one by one and can be connected with the filter slots 3 are provided on the shielding plate 5, a feeding pipe 7 is provided at the left end of the pool body 1, and a discharging pipe 8 is provided at the front and rear sides of the right end of the pool body 1 respectively.

[0018] In order to allow the separation plate 2 to move forward and backward, a rectangular receiving groove 9 is opened on the left side of the pool body 1, and a sliding block 10 is slidably connected to the receiving groove 9. The sliding block 10 is fixedly connected to the separation plate 2 via an L-shaped connecting rod 11, and a stud 12 is provided in the receiving groove 9 in a front-to-back axial direction and threadedly connected to the sliding block 10.

[0019] In order to rotate the stud 12 , a motor 13 is provided at the front side of the receiving slot 9 , and the output shaft of the motor 13 is coaxially and fixedly connected with the stud 12 .

[0020] In order to enable the shielding plate 5 to move up and down, the left and right sides of the front end of the separation plate 2 are respectively provided with slide grooves 14, and the rear end of the shielding plate 5 is provided with a slider 15 that can slide in the slide groove 14. A connecting plate 16 is provided at the upper end of the shielding plate 5. The free end of the connecting plate 16 is inserted into the accommodating groove 9 and is provided with a top plate 17. The accommodating groove 9 is provided with an inclined plate 18 located on the right side of the top plate 17 and lower on the left and higher on the right. The lower end of the top plate 17 is provided with a top column 19 that can contact the inclined plate 18.

[0021] In order to facilitate the movement of the top plate 17 , a clearance groove 20 is provided on the top plate 17 , and the stud 12 is located in the clearance groove 20 .

[0022] In order to facilitate the movement of the connecting rod 11 and the connecting plate 16 , a moving groove communicating with the accommodating groove 9 is opened at the upper end of the cell body 1 .

[0023] In order to facilitate the suction of the dirty liquid, a discharge pump 21 is provided on the discharge pipe 8 .

[0024] When the utility model is in use, firstly, the discharge pipe 8 at the rear side is connected to the biogas slurry pool, and the discharge pipe 8 at the front side is connected to the anaerobic fermentation tank, and then the sewage is introduced into the tank body 1 through the feed pipe 7, and the motor 13 is turned on at this time, and the motor 13 drives the stud 12 to rotate clockwise, and the rotation of the stud 12 drives the sliding block 10 to slide forward in the receiving groove 9, and the sliding block 10 drives the separation plate 2 to move forward through the connecting rod 11, and the separation plate 2 drives the filter screen 4 thereon to move forward, and the filter screen 4 moves forward to filter the fixed objects in the sewage in the tank body 1 and pushes it forward, and the solid matter in the sewage is continuously filtered during the forward pushing process, so that the sewage with a large concentration rich in inorganic matter and microorganisms is located in front of the separation plate 2, and the sewage with a high concentration rich in solid matter is in front of the separation plate 2, and the sewage with a high concentration rich in solid matter is in front of the separation plate 2, and the sewage with a low concentration is behind the separation plate 2;

[0025] When the separation plate 2 moves forward in the tank body 1, it also drives the shielding plate 5 thereon to move forward. The shielding plate 5 drives the top plate 17 to move forward via the connecting plate 16. The top plate 17 drives the top column 19 at the lower end to move forward. After moving forward for a distance, the lower end of the top column 19 contacts the inclined plate 18 and drives the top column 19 to move upward. The top column 19 drives the shielding plate 5 to move upward. The shielding plate 5 drives the connecting groove 6 thereon to move upward. After moving upward for a distance, the connecting groove 6 is not connected with the filter tank 3. Therefore, the shielding plate 5 achieves shielding of the filter tank 3.

[0026] At this time, the motor 13 is turned off, and the motor 13 stops driving the stud 12 to rotate. Due to the self-locking property of the stud 12, the sliding block 10 will not move when the stud 12 stops rotating. At this time, the separation plate 2 divides the sewage in the tank body 1 into two parts. The sewage in front of the separation plate 2 is the sewage with a higher concentration, and the sewage behind the separation plate 2 is the sewage with a lower concentration. At this time, the discharge pump 21 is turned on, and the discharge pump 21 at the rear side inputs the sewage with a lower concentration into the biogas tank for storage, and the discharge pump 21 at the front side inputs the sewage with a higher concentration into the anaerobic fermentation tank for fermentation reaction. Because the sewage input into the fermentation tank has a higher concentration, the efficiency of fermentation and biogas production is higher.

[0027] When the dirty liquid in the pool body 1 is sucked clean, the motor 13 is turned on to reverse, and the motor 13 reverses to drive the stud 12 to rotate counterclockwise, and the stud 12 drives the sliding block 10 to slide backward, and the sliding block 10 drives the separation plate 2 and the baffle plate 5 to move backward. After moving backward for a distance, the top column 19 is out of contact with the inclined plate 18, and the baffle plate 5 moves downward due to its own gravity, so that the connecting groove 6 and the filter tank 3 are reconnected.

[0028] Compared with the prior art, the utility model has the following beneficial effects: the tank body, separation plate, baffle plate, filter screen, etc. are provided, which can realize the concentration separation of the sewage in the tank body, isolate the sewage with higher concentration at the front side of the tank body, isolate the sewage with lower concentration at the rear side of the tank body, and directly input the sewage with lower concentration into the biogas pool for storage, thereby reducing the processing load of the anaerobic fermentation tank and improving the efficiency of manure treatment and anaerobic fermentation. The utility model has a simple structure, novel conception, easy use and strong practicality.

[0029] It should be pointed out that, according to the needs of implementation, the various components described in the embodiments of the present utility model can be split into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of the present utility model.

[0030] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
