[0004] Although there is not much dirt in domestic sewage, most of them are rice grains, melon peels, and domestic organic garbage. These dirt can be completely reused, and the amount of accumulation is large. It is a huge waste, and most of these impurities cannot be directly reused. Although these filtered substances can be used for direct biogas fermentation, without treatment, the fermentation t...

[0024] Example 1: Please refer to Figure 1-4 , a crushing device for treating impurities filtered out of sewage, comprising a crushing box 1, a motor 2 is fixedly connected to the top of the crushing box 1, a horizontal shaft 3 is fixedly connected to the output end of the motor 2, and a driving bevel gear is fixedly connected to the horizontal shaft 3 4. The top of the crushing box 1 is rotatably connected with a driven shaft 5, and the top of the driven shaft 5 is fixedly connected with a driven bevel gear 6, and the driven bevel gear 6 meshes with the driving bevel gear 4;

[0025] When in use, add the impurities filtered out of the sewage into the crushing box 1, turn on the motor 2, the rotation of the motor 2 drives the rotation of the horizontal shaft 3, the rotation of the horizontal shaft 3 drives the rotation of the active bevel gear 4, and then drives the driven shaft 5 through the driven bevel gear 6 turn;

[0026] The bottom of the driven shaft 5 is fixedly connected with a universal coupling 7, the bottom of the universal coupling 7 is connected with a crushing shaft 8, and the bottom of the crushing shaft 8 is fixedly connected with a crushing blade 9;

[0027] The rotation of the driven shaft 5 can drive the crushing shaft 8 to rotate through the universal coupling 7, and the impurities are crushed by the crushing blade 9. Since the impurities are filtered out in the sewage, most of them are paste after crushing. For drying, water can be added appropriately to make it a paste. Due to the different sedimentation coefficients, larger particles such as sand and gravel will settle to the bottom during crushing, and some impurities are difficult to be completely crushed;

[0028] The outer side of the horizontal rotating shaft 3 is fixedly connected with a cam 10, the upper left side of the crushing box 1 is slidably connected with a longitudinal ejector rod 11, the middle part of the longitudinal ejector rod 11 is fixedly connected with a positioning block 12, and the upper part of the positioning block 12 is fixedly connected with a spring 13, and the spring 13 is connected with the The crushing box 1 is fixedly connected, the upper end of the longitudinal ejector rod 11 is offset against the cam 10, the upper end of the crushing shaft 8 is fixedly connected with a rotating plate 14, and the lower end of the longitudinal ejector rod 11 is offset against the rotating plate 14;

[0029] The rotation of the cam 10 drives the longitudinal ejector rod 11 to move up and down, and then drives the crushing shaft 8 to displace through the rotating plate 14, and the crushing blade 9 can crush different positions;

[0030] The right end of the horizontal rotating shaft 3 is fixedly connected with a driving pulley 15, the bottom right side of the crushing box 1 is rotatingly connected with a side rotating shaft 16, and the outer end of the side rotating shaft 16 is fixedly connected with a driven pulley 17, and the driving pulley 15 and the driven pulley 17 is socketed with transmission belt 18, and the rear of crushing box 1 right side is fixedly connected with electric telescopic rod 19, and the output end of electric telescopic rod 19 is connected with tension pulley 20 in rotation, and tension pulley 20 cooperates with transmission belt 18, so The inner end of the side rotating shaft 16 is fixedly connected with a spiral mixing blade 21;

[0031] Intermittently open the electric telescopic rod 19, the electric telescopic rod 19 drives the tension pulley 20 to move, so that the transmission belt 18 is tightened, thereby driving the spiral mixing blade 21 to rotate, so that the filtrate is fully mixed, and the crushing blade 9 is used for more thorough crushing .

[0032] The bottom of the crushing box 1 is fixedly connected with a supporting base 22 symmetrically.

[0033] The spring 13 is sleeved on the outside of the longitudinal push rod 11 .

[0034] The crushing blades 9 are provided with 1-3 groups, preferably, the crushing blades 9 are provided with 2 groups.

Whether the pulverized matter flows out.

[0036] The diameter of the driving bevel gear 4 is greater than the diameter of the driven bevel gear 6 .

[0037] The spring 13 is a metal tension spring.

[0038] The motor 2 and the electric telescopic rod 19 are respectively electrically connected to the power supply through a switch.

[0039] The diameter of the driving pulley 15 is smaller than that of the driven pulley 17 .

Example Embodiment

[0040] Embodiment 2: This embodiment is a further improvement of the previous embodiment: a ball is provided at the bottom of the longitudinal push rod 11, thereby avoiding damage to the rotating plate 14 caused by contact with the rotating plate 14 during the vertical movement of the vertical pushing rod 11. , A transparent observation window can be fixed on the crushing box 1, which is convenient for intuitive understanding of the crushing process.

[0041]The working principle of the present invention is: when in use, add the impurities filtered out of the sewage into the crushing box 1, turn on the motor 2, the rotation of the motor 2 drives the horizontal shaft 3 to rotate, the rotation of the horizontal shaft 3 drives the rotation of the active bevel gear 4, and then passes through the driven cone The gear 6 drives the driven shaft 5 to rotate, and the rotation of the driven shaft 5 can drive the crushing shaft 8 to rotate through the universal coupling 7, and crush the impurities through the crushing blade 9. Since the impurities are filtered out in the sewage, more If the filtrate is dry, you can add water appropriately to make it a paste. Due to the different sedimentation coefficients, larger particles such as sand and gravel will settle to the bottom during crushing, and some impurities are difficult to be completely crushed. The rotation of the cam 10 drives the longitudinal ejector rod 11 to move up and down, and then the rotating plate 14 drives the crushing shaft 8 to displace, the crushing blade 9 can crush different positions, and the electric telescopic rod 19 is intermittently opened, and the electric telescopic rod 19 drives the tension pulley 20 The movement makes the transmission belt 18 tight, thereby driving the spiral mixing blade 21 to rotate, so that the filtrate is fully mixed, and the pulverizing blade 9 is used to pulverize more thoroughly.
