Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and particularly relates to flocculant delivery equipment for sewage treatment. Background Art

[0002] In sewage treatment, flocculant delivery equipment is indispensable. When sewage is treated industrially, it is usually necessary to use a sewage flocculation tank to flocculate and precipitate the sewage. In this process, a certain amount of flocculant is generally required to be added to the sewage tank to accelerate the flocculation and precipitation of the sewage.

[0003] Most of the existing delivery equipment relies on the free diffusion of flocculants and the auxiliary mixing effect of stirring devices to combine flocculants with sewage, resulting in slow and uneven diffusion of flocculants, resulting in low sewage treatment efficiency;

[0004] At the same time, in order to accelerate the flocculation and sedimentation of sewage, the existing devices usually first dissolve the powdered flocculant with clean water in a quantitative ratio at a temperature above 20° and then add it into the sewage for reaction and precipitation. However, the temperature is not enough or the amount of clean water is small, resulting in incomplete dissolution, causing the formed flocculant solution to have agglomerates, which are directly precipitated when added to the sewage, resulting in reduced flocculant utilization and reduced sewage treatment efficiency.

[0005] Therefore, it is necessary to provide a flocculant delivery device for sewage treatment to solve the problems raised in the above background technology. Utility Model Content

[0007] The delivery assembly comprises: a guide tube, sealed and fixed on the outside of the guide hole of the feeding cylinder; a feeding nozzle, linearly connected and arranged on the guide tube; and a connector, slidably arranged on the end of the guide tube away from the feeding cylinder;

[0008] The angle between the topmost group of feeding nozzles and the axis of the feeding barrel is α, and α<90°. Then, the angles between the feeding nozzles from top to bottom and the axis of the feeding barrel are all less than α, and the angles gradually decrease.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The flocculant sprayed from the upper feeding nozzle will impact with the flocculant sprayed from the adjacent lower feeding nozzle at a certain point, so that the two streams of flocculants can diffuse instantly. The flocculant sprayed from the lower feeding nozzle will form a secondary impact at a certain point on the first diffusion boundary line, increasing the diffusion range, so that the flocculant can quickly combine with the sewage and improve the sewage treatment efficiency;

[0018] 2. By setting feeding nozzles at different angles, the agglomerates in multiple flocculants can be gradually disintegrated through mutual collision, so that the flocculants can completely react with the sewage, thereby improving the utilization rate of the flocculants and thus improving the sewage treatment efficiency.

DETAILED DESCRIPTION

[0025] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be an electrical connection; it can be a hydraulic oil circuit connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0026] See also Figure 1 and Figure 5 As shown, a flocculant delivery device for sewage treatment is characterized in that it includes: a connecting plate 1, one end of which is fixed to the upper edge of the sewage pool 2, and a motor 3 is installed on the upper end surface of the other end, and a gear 4 is provided at the output end of the motor 3; a feeding cylinder 5, the lower end of which is sealed and rotatably arranged at the center of the bottom of the sewage pool 2, and the upper end passes through the connecting plate 1 and is provided with a gear 2 6, the gear 2 6 is meshed with the gear 1 4, and a pump body is provided in the feeding cylinder 5; a delivery component 7, which is linearly arranged in multiple groups, each group is circumferentially arranged, and all are arranged on the feeding cylinder 5; and a stirring component 8, which is circumferentially arranged on the feeding cylinder 5 and is distributed at equal angles with the delivery component 7;

[0027] The delivery assembly 7 includes: a guide tube 71, which is sealed and fixed on the outside of the guide hole of the feeding cylinder 5; a feeding nozzle 72, which is linearly connected and arranged on the guide tube 71; and a connector 73, which is slidably arranged on the end of the guide tube 71 away from the feeding cylinder 5;

[0028] The angle between the topmost group of feeding nozzles 72 and the axis of the feeding barrel 5 is α, and α<90°. Then, the angles between the topmost group of feeding nozzles 72 and the axis of the feeding barrel 5 are all less than α, and the angles gradually decrease.

[0029] When treating sewage, the device can be used. First, the flocculant is injected into the feeding cylinder 5 and the pump body and the motor 3 are turned on. The flocculant is rotated and fed into the sewage from the multiple feeding nozzles 72. During the feeding process, Figure 3 As shown, the flocculant sprayed from the upper layer feeding nozzle 72 will impact the flocculant sprayed from the adjacent lower layer feeding nozzle 72 at a certain point, so that the two streams of flocculants can diffuse instantly, and the flocculant sprayed from the lower layer feeding nozzle 72 will form a secondary impact at a certain point on the first diffusion boundary line, increasing the diffusion range, so that the flocculant can quickly combine with the sewage, thereby improving the sewage treatment efficiency;

[0030] Moreover, during the first impact, the agglomerates contained in the two streams of flocculants can quickly disintegrate part of themselves and react with the sewage through the impact between each other, and the other part forms tiny agglomerates. During the second impact, the agglomerates in the flocculant sprayed from the lower feeding nozzle 72 will continue to collide with the tiny agglomerates in the flocculant after the first diffusion, and the impact force gradually weakens. As a result, the agglomerates in the flocculant sprayed from the lower feeding nozzle 72 gradually disintegrate, and the flocculant agglomerates after the first diffusion disintegrate at the same time. Therefore, the two impacts completely disintegrate the flocculant agglomerates, so that they can completely react with the sewage, improve the utilization rate of the flocculant, and thus improve the sewage treatment efficiency.

[0031] In the utility model, Figure 2 and Figure 4 As shown, the stirring assembly 8 includes: a guide groove 81, which is fixed on the outer wall of the feeding barrel 5; a multi-stage lifting rod 82, one end of which is fixed to the top of the guide groove 81, and the other end is fixedly connected to a motor 2 83, and a threaded rod 84 is fixed to the output end of the motor 2 83, and the end of the threaded rod 84 away from the feeding barrel 5 is also slidably connected to a connector 73; and a sleeve 85, which is threadedly connected to the threaded rod 84, and a motor 3 86 is fixed to the lower end of the sleeve 85, and the output end of the motor 3 86 is fixedly connected to a connecting tube 87, and stirring blades 88 are arranged on both sides of the connecting tube 87, and a micromotor is arranged in the connecting tube 87, and the output end of the micromotor is connected to the two stirring blades 88.

[0032] During the process of adding flocculant, the multi-stage lifting rod 82 pushes the motor 2 83 back and forth, and at the same time, the sleeve 85 moves back and forth on the threaded rod 84 driven by the motor 2 83, so that the stirring blade 88 can act on any position of the sewage, and under the drive of the motor 3 86 and the micromotor, the flocculant can be evenly mixed with the sewage, thereby improving the sewage treatment efficiency.

[0033] like Figure 5 As shown, a compression spring 9 is connected between the connecting head 73 and the guide tube 71 and between the connecting head 73 and the threaded rod 84. A ball 10 is rolled inside the end of the connecting head 73 where the compression spring 9 is not provided, so that the guide tube 71 and the threaded rod 84 can fit tightly with the sewage pool 2, thereby improving the end support capacity and allowing the guide tube 71 and the threaded rod 84 to rotate stably.

[0034] To improve the operability of the device, the device also includes: the two stirring blades 88 on the same connecting tube 87 are arranged at 90 degrees, the guide tube 71 is provided with a plug away from the feeding tube 5, and a gasket is provided between the motor 2 83 and the guide groove 81.

[0035] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
