Technical Field

[0001] The utility model relates to the technical field of carbon source addition, in particular to a biomass carbon source addition device under low temperature environment. Background Art

[0002] Biofilter is a biological treatment structure composed of crushed stone or plastic product fillers. The sewage contacts the gaps between the microbial membranes growing on the surface of the fillers, so that the sewage is purified. The biofilter is an artificial biological treatment technology developed from the primitive intermittent sand filter and contact filter based on the principle of soil self-purification and the practice of sewage irrigation.

[0003] At present, the carbon source of biological pools is generally organic matter, such as glucose, fructose, lactose, etc. These organic substances can provide energy and carbon sources for microorganisms, and promote the growth and metabolic activities of microorganisms in biological pools. The degradation of organic matter will release energy, enabling microorganisms to grow and reproduce, and participate in the biological cycle process in the biological pool. When in a low temperature environment, the organic carbon source will clump, which will affect the dissolution of the carbon source to a certain extent when entering the biological pool, affecting normal use. For this reason, we propose a biomass carbon source dosing device under low temperature environment. Utility Model Content

[0014] Compared with the prior art, the utility model provides a biomass carbon source dosing device under low temperature environment, which has the following beneficial effects:

[0015] 1. The biomass carbon source dosing device under low temperature environment is provided with crushing equipment and auxiliary equipment. After the carbon source is initially crushed by the crushing equipment, as the carbon source is continuously accumulated in the sliding frame, the sliding frame moves downward under the action of gravity, and the sliding frame moves downward with the sleeve rod.

[0025] like Figure 1-Figure 7 As shown, the utility model provides a technical solution: a biomass carbon source dosing device under low temperature environment, including a biological pool body 1 and a feed port 2 arranged on the top of the biological pool body 1, and a crushing device 3 and an auxiliary device 4 are arranged inside the feed port 2. The auxiliary device 4 includes: a fixed plate 41, a sleeve 42, a baffle 43, a fixed rod 44, a slide groove 45, a sliding frame 46, a reset spring 47, a sleeve rod 48, an extrusion plate 49, a fixed plate 410, and a spiral slide groove 411.

[0026] The fixed plate 41 is fixed on the inner wall of the feed port 2, a sleeve 42 is rotatably mounted on the bottom of the fixed plate 41, a baffle 43 is fixed on the surface of the sleeve 42, the top of the fixed rod 44 is fixed on the bottom of the fixed plate 41, a slide groove 45 is provided on the inner wall of the feed port 2, a sliding frame 46 is slidably mounted on the inner side of the slide groove 45, a return spring 47 is fixed on the bottom of the sliding frame 46, one end of the return spring 47 away from the sliding frame 46 is fixed on the inner side of the slide groove 45, a sleeve rod 48 is rotatably mounted on the inner side of the sliding frame 46, an extrusion plate 49 is fixed on the surface of the sleeve rod 48, a fixed plate 410 is fixed on the inner side of the sliding frame 46, a spiral slide groove 411 is provided on the inner side of the sleeve rod 48, and the fixed rod 4 The end away from the fixed disk 41 is slidably mounted in the spiral groove 411 on the inner side of the sleeve rod 48, and the sleeve 42 is slidably mounted on the surface of the sleeve rod 48. When the carbon source crushed by the crushing device 3 is put into the fixed disk 41, it falls into the sliding frame 46 through the fixed disk 41. With continuous accumulation, the sliding frame 46 moves downward under the action of gravity, and the sliding frame 46 moves downward with the sleeve rod 48. The fixed rod 44 slides in the spiral groove 411 on the inner side of the sleeve rod 48, so that the sleeve rod 48 drives the extrusion plate 49 to rotate, and the extrusion plate 49 cooperates with the fixed plate 410 to extrude the carbon source, thereby realizing secondary crushing and avoiding the agglomeration of the organic carbon source caused by low temperature, which affects the dissolution of the carbon source.

[0027] A through hole 6 is provided on the bottom of the fixed disk 41 and the baffle 43. When the through hole 6 on the baffle 43 coincides with the through hole 6 at the bottom of the fixed disk 41, the carbon source in the fixed disk 41 can fall into the sliding frame 46 through the fixed disk 41. When the sliding frame 46 moves downward, the sleeve rod 48 on the inner side of the sliding frame 46 rotates, the sleeve rod 48 drives the sleeve 42 to rotate together, and the sleeve 42 drives the baffle 43 to rotate, so that the through hole 6 on the baffle 43 no longer coincides with the through hole 6 at the bottom of the fixed disk 41, thereby stopping the carbon source in the fixed disk 41 from falling.

[0028] The crushing equipment 3 includes an active motor 31, a driven motor 32, an active crushing roller 33 and a driven crushing roller 34. The active motor 31 and the driven motor 32 are both fixed on the surface of the feed port 2. The output shafts of the active motor 31 and the driven motor 32 pass through the feed port 2 and are rotatably connected to the feed port 2. The output shaft of the active motor 31 is fixed to the active crushing roller 33, and the output shaft of the driven motor 32 is fixed to the driven crushing roller 34. The active motor 31 drives the active crushing roller 33 and the driven motor 32 drives the driven crushing roller 34 to work, so as to preliminarily crush the carbon source entering the feed port 2.

[0029] The sliding frame 46 is provided with a feeding mechanism 5, which includes a rotating shaft 51. A groove 53 is provided at the bottom of the sliding frame 46. The rotating shaft 51 is rotatably installed in the groove 53 at the bottom of the sliding frame 46. A volute spring 54 is fixed to the inner side of the groove 53. One end of the volute spring 54 away from the groove 53 is fixed to the surface of the rotating shaft 51. An L-shaped rod 52 is fixed on the surface of the rotating shaft 51. The L-shaped rod 52 penetrates the sliding frame 46 and is slidably connected to the sliding frame 46. A fan-shaped plate 55 is fixed on the surface of the rotating shaft 51. A feeding hole 56 is provided at the bottom of the sliding frame 46. When the sleeve rod 48 drives the extrusion plate 49 to rotate, the extrusion plate 49 no longer squeezes the L-shaped rod 52. Under the action of the volute spring 54, the rotating shaft 51 drives the L-shaped rod 52 and the fan-shaped plate 55 to rotate together, and the fan-shaped plate 55 no longer blocks the feeding hole 56, so that the carbon source in the sliding frame 46 can be fed only after secondary extrusion and crushing, thereby further avoiding affecting the dissolution of the carbon source.

[0030] Crushing teeth 7 are fixed on the surfaces of the extrusion plate 49 and the fixed plate 410, which can improve the extrusion and crushing effect of the carbon source.

[0031] Based on the above implementation, the prepared organic matter carbon source is put into the feed port 2 at the top of the biological pond body 1. When the low temperature causes the organic matter carbon source to clump, the crushing equipment 3 is started, and the active motor 31 drives the active crushing roller 33 and the driven motor 32 drives the driven crushing roller 34 to work, so as to preliminarily crush the carbon source entering the feed port 2.

[0032] The crushed carbon source falls into the fixed disk 41, and then falls into the sliding frame 46 through the through holes 6 on the fixed disk 41 and the baffle 43. As the pressure continues to accumulate, the sliding frame 46 moves downward under the action of gravity, and the sliding frame 46 moves downward with the sleeve rod 48. The fixed rod 44 slides in the spiral groove 411 on the inner side of the sleeve rod 48, so that the sleeve rod 48 drives the extrusion plate 49 to rotate, and the extrusion plate 49 cooperates with the fixed plate 410 to extrude the carbon source to achieve secondary crushing, thereby avoiding the agglomeration of organic carbon sources caused by low temperature and affecting the dissolution of the carbon source.

[0033] When the sliding frame 46 moves downward, causing the sleeve rod 48 on the inner side of the sliding frame 46 to rotate, the sleeve rod 48 drives the sleeve 42 to rotate together, and the sleeve 42 drives the baffle 43 to rotate, so that the through hole 6 on the baffle 43 no longer coincides with the through hole 6 at the bottom of the fixed disk 41, so that the carbon source in the fixed disk 41 can stop falling, and when the sleeve rod 48 drives the extrusion plate 49 to rotate, the extrusion plate 49 no longer squeezes the L-shaped rod 52, and under the action of the volute spring 54, the rotating shaft 51 drives the L-shaped rod 52 and the fan-shaped plate 55 to rotate together, and the fan-shaped plate 55 no longer blocks the feeding hole 56, so that the carbon source in the sliding frame 46 can be fed only after secondary extrusion and crushing, further avoiding affecting the dissolution of the carbon source.

[0034] When the feeding is completed, under the action of the reset spring 47, the sliding frame 46 resets upward. At this time, the sleeve rod 48 drives the extrusion plate 49 to rotate in the opposite direction and reset. The extrusion plate 49 resets and squeezes the L-shaped rod 52, so that the L-shaped rod 52 drives the rotating shaft 51 to rotate and rewind the spiral spring 54. The rotating shaft 51 drives the fan-shaped plate 55 to rotate, and the fan-shaped plate 55 blocks the feeding hole 56 again. At the same time, the baffle 43 is reset, and the through hole 6 on the baffle 43 overlaps with the through hole 6 at the bottom of the fixed disk 41 again. The carbon source in the fixed disk 41 can fall into the sliding frame 46 through the through hole 6 again, and the feeding operation is continued, so as to realize the effect of quantitative feeding and avoid excessive feeding at one time, which affects the efficiency of carbon source dissolution.

[0035] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
