Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and in particular relates to a solution quantitative feeding device for sewage treatment. Background Art

[0002] Wastewater treatment refers to the process of purifying sewage so that it meets the water quality requirements for discharge into a certain water body or reuse. This process is widely used in many fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, catering, etc., and is increasingly entering people's daily lives. According to the source of sewage, sewage treatment is generally divided into industrial sewage treatment and domestic sewage treatment.

[0003] After searching, in the prior art, China Patent Publication No.: CN216972031U, Authorization Date: 2022-07-15, discloses a feeding equipment for sewage treatment, one end of the rotating shaft extends into the inner wall of the box, and the other end is connected to a support column, and a plurality of fan blades are installed on the support column, and a first bevel gear is fixed on the rotating shaft, and the inside of the feeding barrel is connected to the support plate through a connecting rod, and a reciprocating screw is provided inside the feeding barrel, and the reciprocating screw passes through the support plate and is rotatably connected to the inside of the support plate, and the bottom of the reciprocating screw is connected to a second bevel gear, and the first bevel gear and the second bevel gear are meshed with each other, and the top of the reciprocating screw is connected to blades. When sewage enters from the water inlet pipe, the fan blades are driven to move by the high-speed flow of water, thereby causing the rotating shaft to rotate, thereby causing the blades connected to the top of the reciprocating screw to rotate, breaking up larger particles of additives so that they can fully react with the sewage.

[0004] However, the device still has the following defects: although the high-speed flow of water drives the fan blades to move, thereby causing the rotating shaft to rotate, and thus causing the blades connected to the top of the reciprocating screw to rotate, breaking up larger particles of additives so that they can fully react with the sewage, it is impossible to control the amount of additives added. If the feeding equipment cannot accurately control the amount of additives added, it may cause excessive or insufficient additives, thereby affecting the chemical reaction process of sewage treatment, reducing treatment efficiency, and even causing the effluent water quality to not meet standards. If the amount of additives added is not controlled, it may cause corrosion or wear to certain parts of the equipment, resulting in reduced equipment performance and shortening the service life of the equipment.

[0024] The present invention provides a solution quantitative feeding device for sewage treatment, comprising a first liquid storage barrel 1, exemplarily, as Figures 1-4 shown.

[0025] The top of the first liquid storage barrel 1 is fixedly connected to a shell 2, the inner cavity of the shell 2 is provided with a motor 3, the inner cavity of the first liquid storage barrel 1 is provided with a stirring rod 4, one end of the stirring rod 4 passes through the inner cavity of the shell 2 and is transmission-connected to the motor 3, the top of the first liquid storage barrel 1 is connected to a water inlet pipe 5, the surface of the first liquid storage barrel 1 is connected to a water outlet pipe 6, the surface of the water outlet pipe 6 is sleeved with a first solenoid valve 7, the top of the first liquid storage barrel 1 is fixedly connected to a controller 8, the top of the first liquid storage barrel 1 is provided with a second liquid storage barrel 9, the surface of the second liquid storage barrel 9 is connected to a feed pipe 10, the bottom of the second liquid storage barrel 9 is connected to a discharge pipe 11, the surface of the discharge pipe 11 is sleeved with a second solenoid valve 12, and the inner cavity of the second liquid storage barrel 9 is provided with a moving mechanism 13.

[0026] The moving mechanism 13 includes a fixed block 131 disposed in the inner cavity of the second liquid storage barrel 9. Figures 1-4 shown.

[0027] The bottom of the fixed block 131 is fixedly connected to a float 132, and a sensor 133 is embedded in the bottom of the float 132. The top of the fixed block 131 is fixedly connected to a long rod 134, one end of the long rod 134 passes through the top of the second liquid storage barrel 9 and is fixedly connected to a connecting block 135. A guide rod 136 is provided on the outside of the second liquid storage barrel 9, one end of the guide rod 136 is fixedly connected to the connecting block 135, and a guide block 137 is sleeved on the surface of the guide rod 136, and one side of the guide block 137 is fixedly connected to the second liquid storage barrel 9.

[0028] Specifically, due to the precise coordination between the float 132 and the sensor 133, the changes in the liquid level of the flocculant can be monitored in real time. When the liquid level reaches the preset value, the opening and closing of the second solenoid valve 12 are precisely controlled by the controller 8, thereby achieving precise measurement of the amount of flocculant added, avoiding excessive or insufficient amounts. The setting of the guide rod 136 and the guide block 137 increases the stability of the moving mechanism 13, so that the float 132 can remain stable when moving up and down, avoiding errors caused by shaking or tilting.

[0029] The bottom end of the guide rod 136 is fixedly connected to the limiting block 14, and the limiting block 14 is circular in shape. Figures 1-4 shown.

[0030] The top of the second liquid storage barrel 9 is rotatably connected to a box cover 15, and the top of the box cover 15 is fixedly connected to a handle. The surface of the second liquid storage barrel 9 is fixedly connected to a support frame 16, and the bottom of the support frame 16 is fixedly connected to the first liquid storage barrel 1.

The bottom of the inner cavity of the first liquid storage barrel 1 is fixedly connected to a guide plate 19, and the top of the guide plate 19 is provided with an inclined surface.

[0031] Specifically, the setting of the limit block 14 plays a role in limiting the guide rod 136, so that the guide rod 136 is not easily separated from the inner cavity of the guide block 137. The coordinated use of the box cover 15 and the handle makes it convenient for the user to open the box cover 15, thereby cleaning the inner cavity of the second liquid storage barrel 9. The setting of the support frame 16 plays a role in supporting the second liquid storage barrel 9, so that the second liquid storage barrel 9 is not easy to shake when placed. The setting of the support legs 17 plays a role in supporting the sewage treatment device, thereby improving the stability of the sewage treatment device when placed. The coordinated use of the heat dissipation holes 18 and the filter screen plays a role in dissipating heat for the motor 3, thereby extending the service life of the motor 3. The setting of the guide plate 19 plays a role in diverting sewage, thereby facilitating the discharge of sewage.

[0032] The working principle of the solution quantitative feeding device for sewage treatment proposed by the embodiment of the present invention is as follows:

[0033] When the device is in use, the user guides the sewage into the inner cavity of the first liquid storage barrel 1 through the water inlet pipe 5, and then pours the flocculant into the inner cavity of the second liquid storage barrel 9 through the feed pipe 10. As the flocculant continues to increase, the float 132 will be driven to move upward, the float 132 will drive the fixed block 131 to move, the fixed block 131 will drive the long rod 134 to move, and the long rod 134 will drive the connecting block 135 to move. When the connecting block 135 moves, it will drive the guide rod 136 to slide upward in the inner cavity of the guide block 137. The sensor 133 can sense the capacity position of the flocculant. By controlling the controller 8 to open the second solenoid valve 12, the flocculant in the inner cavity of the second liquid storage barrel 9 flows into the inner cavity of the first liquid storage barrel 1 through the discharge pipe 11. As the flocculant decreases, the position of the float 132 will drop. When the float 132 drops to the specified position, the controller 8 is started to control the second solenoid valve 12 to close, thereby realizing the quantitative addition of the flocculant, and the motor 3 is started. The output end of the motor 3 drives the stirring rod 4 to rotate, and the stirring rod 4 mixes the sewage and flocculant in the inner cavity of the first liquid storage barrel 1, thereby improving the sewage treatment efficiency.

[0034] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
