Description
Technical Field
[0001] The utility model belongs to the technical field of sewage treatment, and particularly relates to a flocculant feeding and mixing device. Background Art
[0002] A flocculant feeding and mixing device is a special device used to uniformly disperse flocculants into water during the water treatment process. Such devices usually include a dosing system and a mixing unit, which can ensure efficient contact between the flocculant and the suspended solids in the water and promote the formation of flocs. Common devices include metering pumps, mixing tanks, and static mixers, etc. Although the existing flocculant feeding and mixing devices can complete the mixing work of the flocculant, there are still disadvantages. The mixing speed of the existing flocculant feeding and mixing devices is relatively low, and it cannot effectively stir, resulting in the flocculant precipitating at the bottom of the water body, unable to fully mix the flocculant and water, resulting in uneven distribution of the flocculant and affecting the treatment effect. The conventional countermeasure is to adjust the rotation speed and mixing time of the device to enhance the contact between the flocculant and water. However, the disadvantage of this method is that increasing the mixing speed may lead to an increase in energy consumption and thus an increase in operating costs. Therefore, a new structure is proposed to solve the above problems. Summary of the Utility Model
[0003] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a flocculant feeding and mixing device.
[0004] The utility model is realized through the following technical solutions: A flocculant feeding and mixing device, comprising: a mixing device main body, an equalizing box, and a stirring group. A transmission shaft is arranged above the interior of the mixing device main body. A guide material circular groove is arranged on the left side of the transmission shaft. The equalizing box is arranged outside the transmission shaft.
[0005] The top of the equalizing box is a through structure. A shaft hole is opened at the center of the bottom of the equalizing box. A plurality of groups of leakage holes are arranged through the bottom of the equalizing box. A stirring group is arranged below the equalizing box. The stirring group is composed of a stirrer one and a stirrer two.
[0006] The stirrer one is composed of a stirring blade one and a fixed sleeve one. The stirrer two is composed of a stirring blade two and a fixed sleeve two. The stirrer two is fixedly welded to the outer side above the bottom of the transmission shaft. The stirrer one is above the stirrer two and is fixedly welded to the outer side of the transmission shaft.
[0007] As a preferred embodiment, a top cover is arranged on the top of the mixing device main body. A motor is arranged above the top cover. The motor is a servo motor. The top of the transmission shaft is connected to the output end of the bottom of the motor.
[0008] A feed pipe is provided on the left side at the top of the top cover. A water inlet pipe is provided below the left side of the main body of the mixing device. A discharge port is provided at the bottom of the main body of the mixing device. Four groups of legs are welded equidistantly at the bottom of the main body of the mixing device.
[0009] As a preferred embodiment, the outer side of the transmission shaft is fixedly welded to the shaft hole at the center of the bottom of the equalizing box. The equalizing box is made of stainless steel. The radius length of the through part at the top of the equalizing box is smaller than the radius length of the equalizing box.
[0010] As a preferred embodiment, the horizontal height of the highest point of the equalizing box is smaller than the horizontal height of the lowest point of the material guiding circular groove. The material guiding circular groove is made of stainless steel. The left side of the material guiding circular groove is fixedly welded to the inner wall of the main body of the mixing device;
[0011] The right side of the material guiding circular groove is directly above the through part at the top of the equalizing box. The material guiding circular groove is an inclined surface structure with a gradually decreasing slope from left to right. The material guiding circular groove is a semi-circular groove structure.
[0012] As a preferred embodiment, the first stirring blade and the first fixed sleeve are of an integral structure. The first stirring blade is an inclined surface structure with an angle of 45 degrees to the horizontal line. Four groups of the first stirring blades with the same specifications are provided.
[0013] As a preferred embodiment, the second stirring blade and the second fixed sleeve are of an integral structure. The second stirring blade is an inclined surface structure with an angle of 45 degrees to the horizontal line. Four groups of the first stirring blades with the same specifications are provided. During actual use, the first stirrer and the second stirrer mix and stir the clear water and the flocculant particles driven by the rotation of the transmission shaft. The first stirrer stirs the upper layer of the clear water, and the second stirrer stirs the lower layer of the clear water, so as to fully mix and stir the clear water and the flocculant particles. With the heating assistance of the two groups of heating plates for the clear water, the mixing efficiency of the clear water and the flocculant particles is greatly improved. At the same time, the equalizing box, the first stirrer and the second stirrer are driven by a group of transmission shafts and a group of motors, which greatly reduces the mixing energy consumption and the operating cost.
[0014] As a preferred embodiment, a group of heating plates are embedded and installed on the left and right sides below the interior of the main body of the mixing device. The two groups of heating plates have the same specifications and are arranged in mirror symmetry. During actual use, the motor is started and the two groups of heating plates are connected. The motor rotates to drive the transmission shaft to rotate inside the main body of the mixing device, thereby driving the equalizing box, agitator one, and agitator two to rotate respectively. The two groups of heating plates heat the clear water, increasing the dissolution temperature of the clear water, thereby increasing the dissolution rate of the flocculant particles and clear water, reducing energy consumption. Then, the flocculant particles are injected into the interior of the main body of the mixing device through the feed pipe. The flocculant particles first fall into the interior of the guiding circular groove and slide to the right along the inclined plane of the guiding circular groove that slopes from left to right, and finally fall downward from the right side of the guiding circular groove into the interior of the equalizing box. The equalizing box rotates following the rotation of the transmission shaft, and uses the centrifugal force of rotation to disperse the flocculant particles inside the equalizing box to the surrounding areas inside the equalizing box. The radius length of the through hole at the top of the equalizing box is smaller than the radius length of the equalizing box, thereby preventing the flocculant particles from flying out of the interior of the equalizing box. Then, the flocculant particles fall downward into the clear water through a number of groups of leakage holes. The final effect is that the flocculant particles are evenly distributed in the clear water through the centrifugal force of the equalizing box, thereby accelerating the mixing rate and then reducing the mixing energy consumption.
[0015] After adopting the above technical solution, the beneficial effects of the present utility model are as follows: By setting the guiding circular groove, equalizing box, and transmission shaft, the flocculant particles enter the interior of the guiding circular groove through the feed pipe and fall into the interior of the equalizing box along the guiding circular groove to the right. The equalizing box rotates and evenly disperses the flocculant particles to the surrounding areas through centrifugal force, and the flocculant particles fall downward into the lower part inside the main body of the mixing device through the leakage holes, thereby enabling the flocculant particles to be evenly distributed in the clear water, improving the mixing efficiency of the flocculant particles and clear water. By setting the agitator one and agitator two, the clear water and flocculant particles can be stirred. The agitator one stirs the upper layer of the clear water, and the agitator two stirs the lower layer of the clear water, thereby fully stirring the flocculant particles and clear water, accelerating the mixing rate of the flocculant particles and clear water, and then reducing the energy consumption.

[0025] Please refer to Figures 1 to 4 : A flocculant feeding and mixing device, including: main body 100 of the mixing device, equalizing box 170, and stirring group 180. There is a transmission shaft 150 above the interior of the main body 100 of the mixing device. There is a guide material circular groove 160 on the left side of the transmission shaft 150, and an equalizing box 170 is arranged outside the transmission shaft 150;
[0026] The top of the equalizing box 170 is a through - structure. There is a shaft hole at the center of the bottom of the equalizing box 170. A number of groups of leakage holes 230 are arranged through the bottom of the equalizing box 170. A stirring group 180 is arranged below the equalizing box 170. The stirring group 180 is composed of stirrer one 210 and stirrer two 220;
[0027] Stirrer one 210 is composed of stirring blade one and fixed sleeve one. Stirrer two 220 is composed of stirring blade two and fixed sleeve two. Stirrer two 220 is fixedly welded to the outside above the bottom of the transmission shaft 150. Stirrer one 210 is above stirrer two 220 and is fixedly welded to the outside of the transmission shaft 150.
[0028] At the top of the mixing device main body 100, there is a top cover 110. Above the top cover 110, there is a motor 120, and the motor 120 is a servo motor 120. The top of the transmission shaft 150 is connected to the output end at the bottom of the motor 120;
[0029] On the left side at the top of the top cover 110, there is a feed pipe 130. On the lower left side of the mixing device main body 100, there is a water inlet pipe 140. At the bottom of the mixing device main body 100, there is a discharge port 200. At the bottom of the mixing device main body 100, four groups of legs are welded at equal intervals.
[0030] The outer side of the transmission shaft 150 is welded and fixed to the shaft hole at the center of the bottom of the equalizing box 170. The equalizing box 170 is made of stainless steel, and the radius length of the through part at the top of the equalizing box 170 is less than the radius length of the equalizing box 170.
[0031] The horizontal height of the highest point of the equalizing box 170 is less than the horizontal height of the lowest point of the material guiding circular groove 160. The material guiding circular groove 160 is made of stainless steel, and the left side of the material guiding circular groove 160 is welded and fixed to the inner wall of the mixing device main body 100;
[0032] The right side of the material guiding circular groove 160 is directly above the through part at the top of the equalizing box 170. The material guiding circular groove 160 is an inclined surface structure with a gradually decreasing slope from left to right, and the material guiding circular groove 160 is a semi-circular groove structure.
[0033] The first stirring blade and the first fixing sleeve are an integral structure. The first stirring blade is an inclined surface structure with an angle of 45 degrees to the horizontal line, and there are four groups of the first stirring blades with the same specifications.
[0034] The second stirring blade and the second fixing sleeve are an integral structure. The second stirring blade is an inclined surface structure with an angle of 45 degrees to the horizontal line, and there are four groups of the first stirring blades with the same specifications. In actual use, the first stirrer 210 and the second stirrer 220 mix and stir the clear water and the flocculant particles under the drive of the rotation of the transmission shaft 150. The first stirrer 210 stirs the upper layer of the clear water, and the second stirrer 220 stirs the lower layer of the clear water, so as to fully mix and stir the clear water and the flocculant particles. With the heating assistance of the two groups of heating plates 190 for the clear water, the mixing efficiency of the clear water and the flocculant particles is greatly improved. At the same time, the equalizing box 170, the first stirrer 210 and the second stirrer 220 are driven by a set of transmission shaft 150 and a set of motor 120, which greatly reduces the mixing energy consumption and the operating cost.
[0035] There are a set of heating plates 190 embedded and installed on the left and right sides at the lower part inside the mixing device main body 100. The two sets of heating plates 190 have the same specifications and are arranged in mirror symmetry. During actual use, start the motor 120 and turn on the two sets of heating plates 190. The rotation of the motor 120 drives the transmission shaft 150 to rotate inside the mixing device main body 100, thereby driving the equalizing box 170, the first stirrer 210, and the second stirrer 220 to rotate respectively. The two sets of heating plates 190 heat the clear water, increasing the dissolution temperature of the clear water, thereby increasing the dissolution rate of the flocculant particles and clear water, reducing energy consumption. Then, the flocculant particles are injected into the mixing device main body 100 through the feed pipe 130. The flocculant particles first fall into the inside of the guiding circular groove 160 and slide to the right along the inclined plane of the guiding circular groove 160 that slopes from left to right, and finally fall downward from the right side of the guiding circular groove 160 into the inside of the equalizing box 170. The equalizing box 170 rotates following the rotation of the transmission shaft 150, and uses the centrifugal force of rotation to disperse the flocculant particles inside the equalizing box 170 to the surrounding of the inside of the equalizing box 170. The radius length of the through hole at the top of the equalizing box 170 is smaller than the radius length of the equalizing box 170, thereby preventing the flocculant particles from flying out of the inside of the equalizing box 170. Then, the flocculant particles fall downward into the clear water through a number of sets of leakage holes 230. The final effect is that the flocculant particles are evenly distributed in the clear water through the centrifugal force of the equalizing box 170, thereby accelerating the mixing rate and then reducing the mixing energy consumption.
[0036] Example 1: Please refer to Figure 1 、 Figure 2 and Figure 4, during actual use, first, inject a sufficient amount of clear water into the lower part inside the mixing device main body 100 through the water inlet pipe 140. Then, start the motor 120 and turn on the two groups of heating plates 190 respectively. The rotation of the motor 120 drives the transmission shaft 150 to rotate inside the mixing device main body 100, thereby driving the equalizing box 170, the first stirrer 210, and the second stirrer 220 to rotate respectively. The two groups of heating plates 190 heat the clear water to increase the dissolution temperature of the clear water, thereby increasing the dissolution rate of the flocculant particles and clear water, reducing energy consumption. Then, inject the flocculant particles into the mixing device main body 100 through the feed pipe 130. The flocculant particles first fall into the inside of the guide material circular groove 160, and slide to the right along the inclined surface of the guide material circular groove 160 that is inclined from left to right, and finally fall downward from the right side of the guide material circular groove 160 into the inside of the equalizing box 170. The equalizing box 170 rotates following the rotation of the transmission shaft 150, and uses the rotational centrifugal force to disperse the flocculant particles inside the equalizing box 170 to the periphery inside the equalizing box 170. The radius length of the through hole at the top of the equalizing box 170 is smaller than the radius length of the equalizing box 170, thereby preventing the flocculant particles from flying out of the inside of the equalizing box 170. Then, the flocculant particles fall downward into the clear water through a plurality of groups of leakage holes 230. The final effect is that the flocculant particles are evenly distributed in the clear water through the centrifugal force of the equalizing box 170, thereby accelerating the mixing rate and then reducing the mixing energy consumption.
[0037] Embodiment 2: Please refer to Figures 1 to 3 , after the flocculant particles enter the clear water, the first stirrer 210 and the second stirrer 220 mix and stir the clear water and the flocculant particles driven by the rotation of the transmission shaft 150. The first stirrer 210 stirs the upper layer of the clear water, and the second stirrer 220 stirs the lower layer of the clear water, thereby fully mixing and stirring the clear water and the flocculant particles. With the heating assistance of the two groups of heating plates 190 for the clear water, the mixing efficiency of the clear water and the flocculant particles is greatly improved. At the same time, the equalizing box 170, the first stirrer 210, and the second stirrer 220 are driven by a set of transmission shaft 150 and a set of motor 120, greatly reducing the mixing energy consumption and the operating cost.
[0038] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
