Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an automatic dosing device for granular sewage treatment agents. Background Art

[0002] With the acceleration of industrialization and the improvement of urbanization, sewage treatment has become an indispensable part of environmental protection and sustainable development. In the sewage treatment process, the addition of chemicals is one of the key steps to ensure the treatment effect.

[0003] Some chemicals used in sewage treatment are granular solids, such as disinfectants and ammonia nitrogen removers. Currently, although there are corresponding delivery devices for granular sewage treatment chemicals, the operation method relies more on manual operation, which is not fast or intelligent enough. In addition, the dosing point is fixed and single, and the dosed chemicals are concentrated somewhere in the treatment pool, which results in a long time for the chemicals to diffuse in the water body, affecting the efficiency of sewage treatment.

[0004] Therefore, the utility model proposes an automatic dosing device for granular sewage treatment agents to solve the above problems. Utility Model Content

[0005] The embodiment of the utility model aims to provide an automatic dosing device for granular sewage treatment agents to solve the above-mentioned problems.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] An automatic dosing device for granular sewage treatment agents is installed in a sewage treatment tank, comprising a drug box, a connected feeding barrel is provided at the bottom of the drug box, a rotatable feeding auger for conveying granular sewage treatment agents is provided in the feeding barrel, a discharging piece is provided in the sewage treatment tank and can reciprocate along the direction of the sewage treatment tank when dosing, feeding holes are evenly arranged on the bottom side of the discharging piece, a material guiding hose is provided between the discharging end of the feeding barrel and the feeding end of the discharging piece, a flow sensor for real-time sensing of sewage flow rate is provided in the water inlet of the sewage treatment tank, and a variable speed motor for driving the feeding auger to rotate and linked to the flow sensor is provided on the feeding barrel.

[0008] In an optional solution, the medicine box is provided with a material level sensor for real-time monitoring of the remaining medicine amount inside the medicine box and a buzzer for starting to sound when the material level sensor detects that the remaining medicine amount inside the medicine box is insufficient.

[0009] In an optional scheme: two rotatable threaded rods are provided in the sewage treatment, two protrusions corresponding to the two threaded rods are provided on the discharge piece, and the two threaded rods are respectively threadedly fitted through the two protrusions, a driving part is provided at the driving end of one of the two threaded rods, and a transmission part is provided between the two threaded rods.

[0010] In an optional solution: the material guiding hose is a stainless steel hose.

[0011] In an optional solution: a vibrator is also provided on the discharge member.

[0012] Compared with the prior art, the beneficial effects of the embodiments of the present invention are as follows:

[0013] When sewage enters the sewage treatment tank through the water inlet, the dosing device automatically starts and continues to dosing as the water inflow process. When the flow rate sensor senses the flow rate, it means that sewage has entered the sewage treatment tank. At this time, the variable speed motor starts and the discharge piece reciprocates along the direction of the sewage treatment tank. The variable speed motor drives the feed auger to rotate so that the granular agent enters the discharge piece through the feed barrel and the guide hose in turn. The granular agent entering the discharge piece is filled along the direction of the discharge piece and discharged through the discharge hole, so that the agent is evenly delivered to the treatment tank, which is beneficial to the efficient and uniform diffusion of the agent in the water body and improves the sewage treatment efficiency. The flow rate sensor senses the sewage flow rate in real time and controls the adaptive adjustment of the variable speed motor speed. The dosing is completed when the water inflow is completed, which greatly improves the intelligence of the granular sewage treatment agent delivery, which is both worry-free and efficient.

DETAILED DESCRIPTION

[0020] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0021] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] See also Figure 1 to Figure 3 , an automatic dosing device for granular sewage treatment agents is arranged at a sewage treatment pool, comprising a drug box 1, a connected feeding barrel 4 is arranged at the bottom of the drug box 1, a rotatable feeding auger 11 for conveying granular sewage treatment agents is arranged in the feeding barrel 4, a discharging piece 6 which can reciprocate along the direction of the sewage treatment pool when dosing is arranged in the sewage treatment pool, feeding holes 14 are evenly arranged on the bottom side of the discharging piece 6, a material guiding hose 5 is arranged between the discharging end of the feeding barrel 4 and the feeding end of the discharging piece 6, a flow velocity sensor 10 for real-time sensing of sewage flow velocity is arranged in the water inlet of the sewage treatment pool, and a variable speed motor 12 for driving the feeding auger 11 to rotate and linked with the flow velocity sensor 10 is arranged on the feeding barrel 4.

[0023] When sewage enters the sewage treatment tank through the water inlet, the dosing device automatically starts and continues to dosing with the water inlet process. When the flow rate sensor 10 senses the flow rate, it means that sewage has entered the sewage treatment tank. At this time, the variable speed motor 12 starts and the discharge piece 6 reciprocates along the direction of the sewage treatment tank. The variable speed motor 12 drives the feeding auger 11 to rotate so that the granular medicine passes through the feeding barrel 4 and the guiding hose 5 into the discharge piece 6 in turn. The granular medicine entering the discharge piece 6 is filled along the direction of the discharge piece 6 and discharged through the discharge hole 14, so that the medicine is evenly delivered to the treatment tank, which is beneficial to the efficient and uniform diffusion of the medicine in the water body, and the sewage treatment efficiency is improved. The flow rate sensor 10 senses the sewage flow rate in real time and controls the adaptive adjustment of the speed of the variable speed motor 12 (the faster the sewage flow rate, the greater the amount of sewage entering the sewage treatment pool per unit time, and the amount of medicine matching the amount of sewage also becomes larger accordingly. Therefore, the faster the water inlet speed, the faster the speed of the variable speed motor 12, and the greater the amount of medicine dosed per unit time, so that the amount of medicine dosed per unit time matches the water inlet volume per unit time). When the water inlet is completed, the medicine dose is completed, which greatly improves the intelligence of the granular sewage treatment agent delivery, which is both worry-free and efficient. It should be noted that the linkage between the flow rate sensor 10 and the variable speed motor 12 belongs to the existing mature control technology and there is no technical obstacle, so it will not be elaborated here.

[0024] Furthermore, the model of the flow velocity sensor 10 is: YF-B5.

[0025] Furthermore, the medicine box 1 is provided with a level sensor 3 for real-time monitoring of the remaining medicine in the medicine box 1 and a buzzer 2 for starting to sound when the level sensor 3 detects that the remaining medicine in the medicine box 1 is insufficient. The buzzer 2 reminds the staff to replenish the medicine in time.

[0026] Furthermore, the material guiding hose 5 is a stainless steel hose, which will not cut off the medicine delivery due to bending, and has high strength and good durability.

[0027] See also Figure 1 and Figure 3 In one embodiment of the utility model, two rotatable threaded rods 9 are provided in the sewage treatment, and two protrusions 13 corresponding to the two threaded rods 9 are provided on the discharge member 6, and the two threaded rods 9 are threadedly matched to penetrate the two protrusions 13 respectively, and one of the two threaded rods 9 is provided with a driving member 7 at its driving end, and a transmission member 8 is provided between the two threaded rods 9.

[0028] It should be noted that the transmission member 8 includes a transmission structure composed of a plurality of transmission wheels, transmission chains or transmission belts, and the driving member 7 is a rotating device such as a reduction motor, a servo motor, etc. in the prior art. All of the above belong to existing mature technologies, so they will not be elaborated here.

[0029] In this embodiment, under the transmission action of the transmission member 8, the output shaft of the driving member 7 rotates alternately in forward and reverse directions to drive the two threaded rods 9 to rotate alternately in forward and reverse directions synchronously, thereby driving the discharge member 6 to move back and forth along the sewage treatment tank and evenly delivering the agent into the treatment tank.

[0030] Furthermore, in this embodiment, a vibrator 15 is provided on the discharging member 6, and the vibrator 15 is used to put the discharging member 6 into a vibrating state, so as to shake off the granular medicine in the discharging member 6, thereby achieving smooth discharging and avoiding blockage.

[0031] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.

[0032] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
