Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering, in particular to municipal sludge treatment and dehydration equipment. Background Art

[0002] In municipal engineering, during sewage treatment, a large amount of sludge will be produced after sewage filtration and sedimentation, and the sludge needs to be treated. At the same time, sludge treatment: the sludge is concentrated, tempered, dehydrated, stabilized, dried or incinerated, and other processing processes for reduction, stabilization, and harmlessness. During sludge treatment, the sludge needs to be dehydrated. When dehydrating the sludge, the sludge is squeezed by an extrusion device. After the sludge is squeezed, the sludge can be carried with it for dehydration.

[0003] When the existing screw stack sludge dewatering machine is in use, it is necessary to dissolve the flocculant and mix it with the sewage before solid-liquid separation. The flocculants used in the existing screw stack sludge dewatering machine are mostly in powder form, which requires the staff to dissolve the flocculant before use. However, when most of the existing dewatering machines are in use, the flocculant is directly put into water for dissolution. However, putting the flocculant in one time will lead to failure to dissolve in time, and it is easy to coagulate into lumps, forming glutinous rice balls and large and small particles, which will not only affect the flocculation effect on the sewage, but also easily lead to the situation that the proportion of flocculant is not accurate enough.

Under this action, the sewage inside the flocculation mechanism 1 can be separated into solid and liquid, so that the sludge is dehydrated. A connecting shell 3 is fixedly connected to one side of the flocculation mechanism 1. The connecting shell 3 is used to mix and dissolve the flocculation agent, so as to facilitate the use of the flocculation mechanism 1. A feed pump 4 is installed on the connecting shell 3. The water inlet of the feed pump 4 is connected to the bottom of the connecting shell 3. The two shells are interconnected, and the water outlet of the feed pump 4 cooperates with the flocculation mechanism 1.

The other end of the support rod 13 is fixedly connected to a protective shell 14. The stepper motor 7 is located inside the protective shell 14. Under this action, the stepper motor 7 can be protected, so that the stepper motor 7 will not easily come into contact with the flocculation raw materials, avoiding the flocculation raw materials from coming into contact with the stepper motor 7 and causing it to be easily damaged. The surface of the output shaft of the stepper motor 7 is fixedly connected with a mounting shaft 8, and the surface of the mounting shaft 8 is slidably connected with a distribution plate 9. The mounting shaft 8 is designed as a cube, under this effect, the distribution plate 9 can be driven to rotate when the mounting shaft 8 rotates, thereby facilitating the discharge of the flocculation raw materials, and the shape will not affect the sliding of the distribution plate 9 on the surface of the mounting shaft 8. The top of the distribution plate 9 is designed as an inclined structure, under this effect, the distribution plate 9 can discharge the flocculation raw materials through centrifugal force when it rotates, and the flocculation raw materials can also be dispersed under the action of the distribution plate 9, thereby making the flocculation The raw material can be dissolved quickly, and a blocking bar 10 is fixedly connected to the surface of the distribution plate 9. There are several blocking bars 10, which can block the flocculation raw material, thereby increasing the moving distance of the flocculation raw material, thereby improving the uniformity of the flocculation raw material. An adjustment mechanism 11 is installed on the inner wall of the support frame 5, and the adjustment mechanism 11 can adjust the position of the distribution plate 9, so that the adjustment mechanism 11 blocks the bottom of the feeding shell 6, thereby achieving the effect of controlling the discharge amount of the flocculation raw material, thereby improving the applicability of the equipment. A stirring mechanism 12 is installed on the surface of the mounting shaft 8, and the stirring mechanism 12 can stir the water and the flocculation raw material inside the connecting shell 3, so that the flocculation raw material can be dissolved in the water.

[0022] The adjusting mechanism 11 comprises an electric telescopic rod 111, the top of which is fixedly connected to the inner wall of the supporting frame 5, and the output shaft of the electric telescopic rod 111 is fixedly connected to a positioning frame 112, the positioning frame 112 is of an L-shaped structure design, and a positioning groove 113 is provided on the surface of the distributing disc 9, and the inner wall of the positioning groove 113 is slidably connected to the surface of the positioning frame 112, and the cross-sectional shape of the positioning groove 113 is of a T-shaped structure design, under this action, the positioning frame 112 will not be easily separated from the inner wall of the positioning groove 113, and under this action, the distributing disc 9 can be guided when it rotates, so that the distributing disc 9 can be more stable when rotating, and the distributing disc 9 can be adjusted with the cooperation of the electric telescopic rod 111, the positioning frame 112 and the positioning groove 113, so as to control the discharge amount of the flocculation raw material and improve the applicability of the equipment.

The rotating shaft 122 is moved to stir the water and flocculation raw materials inside the connecting shell 3, thereby facilitating the dissolution of the flocculation raw materials. The top and bottom of the rotating shaft 122 are fixedly connected with bearing seats 15. The top of the upper bearing seat 15 is fixedly connected to the inner wall of the support frame 5, and the bottom of the lower bearing seat 15 is fixedly connected to the bottom of the inner cavity of the connecting shell 3.

Under the action of the stepper motor 7, the distribution plate 9 can be driven to rotate through the installation shaft 8, and the flocculation raw material can be scattered into the interior of the connecting shell 3 under the cooperation of the distribution plate 9 and the blocking bar 10. Then, under the cooperation of the installation shaft 8 and the transmission component 121, the stirring rod 123 is rotated through the rotating shaft 122, so that the stirring rod 123 stirs the water and flocculation raw material inside the connecting shell 3, so that the water and the flocculation raw material can be mixed together, and then the feed pump 4 is turned on to discharge the dissolved flocculation solution inside the connecting shell 3 into the flocculation mechanism 1, and then the flocculation mechanism 1 is turned on to mix the sewage and the flocculation solution, and then the mixed sewage is separated from the inside of the separation mechanism 2.
