A treatment agent spreading device for sewage treatment

Abstract

This invention discloses a treatment agent spreading device for wastewater treatment, relating to the field of environmental pollution treatment technology. It includes a material receiving box, a liquid supply pump, a mounting cover, a feeding mechanism, and a discharge assembly. The invention utilizes a feeding mechanism and a discharge assembly mounted on the mounting cover. A drive motor's output drives a rotating rod, whose end, via gears, drives two meshing gear discs on either side to rotate synchronously in opposite directions. This ensures the solid alkali source treatment agent is evenly distributed within the discharge box, allowing for sufficient replenishment of the solid alkali source treatment agent in the wastewater, resulting in more thorough treatment. The rotation of the lever also causes a "U"-shaped component to slide on the positioning frame. Combined with the elasticity of the spring, this causes the "U"-shaped component to reciprocate on the positioning frame, preventing blockage of the solid alkali source treatment agent in the discharge holes and ensuring even diffusion of the dispersed solid alkali source treatment agent in the wastewater.

Description

Technical Field

[0001] This invention relates to the field of environmental pollution treatment agent production technology, and specifically to a treatment agent application device for wastewater treatment. Background Technology

[0002] Ferric chloride is another commonly used wastewater treatment agent, typically produced as a high-concentration liquid. It is readily soluble in water, produces large and heavy flocs, exhibits good settling properties, and has a wide adaptability to temperature, water quality, and pH. Its mechanism of action involves the stepwise hydrolysis of ferric ions to generate various ferric hydroxides, which flocculate impurities in the water. However, the formation of these ferric hydroxides requires a large amount of hydroxyl groups in the water, thus consuming a significant amount of alkali during use and necessitating the replenishment of alkali sources such as lime. Current technology involves injecting the liquid treatment agent into the water through a pump pipe, followed by manual addition of a solid treatment agent.

[0003] However, after long-term use, the existing technology has been found to have certain drawbacks, such as: First, after flocculation, the impurities in the sewage settle below the water level in the sewage treatment container. However, after the solid treatment agent is added, the flocculent impurities adhere to and encapsulate the alkali source solids, which may hinder their diffusion in the sewage. Second, the solid treatment agent is unevenly distributed in the sewage, that is, the dosage is larger near the distribution point and relatively smaller further away from the distribution point. The alkali source cannot be fully replenished, resulting in incomplete sewage treatment. Summary of the Invention

[0004] The purpose of this invention is to provide a treatment agent application device for wastewater treatment, so as to solve the above-mentioned defects caused by the prior art.

[0005] A treatment agent spreading device for wastewater treatment includes a material receiving box and a liquid supply pump, and also includes a mounting cover plate, a feeding mechanism and a discharge assembly. The mounting cover plate is installed on a wastewater treatment container, the feeding mechanism is installed on the mounting cover plate, the material receiving box and the liquid supply pump are both installed inside the feeding mechanism, and the discharge assembly is installed on the feeding mechanism.

[0006] Preferably, the feeding mechanism includes a driving motor, a material guiding plate, and a spiral conveying roller. The driving motor is installed on the mounting cover plate through a positioning frame. A rotating rod is installed at the output end of the driving motor. A gear is installed at the lower end of the rotating rod. A shifting rod is fixedly installed in the middle of the positioning frame. Symmetrically arranged tooth discs are installed at the lower part of the positioning frame. The tooth discs are meshed with the gear. The material guiding plate is rotatably installed at the upper part of the positioning frame. The material receiving box is installed at the upper part of the material guiding plate. The spiral conveying roller is fixedly installed on the back of the tooth disc on one side close to the material guiding plate. The other end of the spiral conveying roller is rotatably installed on the blanking component. Both sides of the positioning frame are movably connected with a "C"-shaped part through springs. A plurality of evenly distributed liquid spraying heads are fixedly installed on the back of the tooth disc on the side far from the material guiding plate. The liquid supply pump is installed on the positioning frame through an inclined plate. The liquid supply pump is communicated with the plurality of liquid spraying heads.

[0007] Preferably, the blanking component includes a movable plate and a blanking box. There are two movable plates which are slidably arranged on the positioning frame. The movable plates are also fixedly arranged at the ends of the "C"-shaped parts. The movable plates cooperate with the inclined plate at the lower end. The blanking box is fixedly installed on the positioning frame and is placed directly below the material guiding plate. The upper end of the blanking box cooperates with the spiral conveying roller. A liquid inlet is opened at the side end of the blanking box. A plurality of evenly distributed blanking holes are also opened at the lower end of the blanking box.

[0008] Preferably, the shifting rod cooperates with the back of the material guiding plate and the upper part of the "C"-shaped part in the horizontal direction.

[0009] Preferably, the apertures of the plurality of blanking holes gradually become smaller along the length direction of the blanking box.

[0010] Preferably, the aperture of the blanking hole on the side close to the inclined plate is the largest.

[0011] The advantages of the present invention are as follows:

[0012] By arranging the feeding mechanism and the blanking component on the mounting cover plate, the rotating rod is driven to rotate by the output end of the driving motor. The two tooth discs meshed with the gear at both sides are synchronously rotated in opposite directions at the end. The solid alkali source treatment agent in the material receiving box falls into the blanking box along the material guiding plate. The rotation of the spiral conveying roller makes the solid alkali source treatment agent disperse and spread at each blanking hole. The rotation of the rotating rod also drives the shifting rod in the middle to rotate, and then拨动 the material guiding plate to swing, so that the solid alkali source treatment agent is evenly arranged in the blanking box. The solid alkali source treatment agent is fully supplemented in the sewage, and the treatment is more thorough;

[0013] The rotation of the lever will also move the "C"-shaped part to slide on the positioning frame. With the elastic effect of the spring itself, the "C"-shaped part slides back and forth on the positioning frame. The high-concentration liquid treatment agent ejected from the rotating liquid spraying head flows obliquely downward along the inclined plate and enters the liquid inlet, rinsing the solid alkali source treatment agent falling from each blanking hole. This can not only prevent the solid alkali source treatment agent from clogging in the blanking hole, but also enable the solid alkali source treatment agent to be quantitatively mixed with the high-concentration liquid treatment agent first, avoiding the solid alkali source treatment agent being wrapped by impurity flocs after entering the sewage, and the solid alkali source treatment agent scattered and sown diffuses evenly in the sewage.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] To make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0021] As Figures 1 to 5 shown, a treatment agent spreading device for sewage treatment includes a material receiving box 1 and a liquid supply pump 2, and also includes an installation cover plate 3, a feeding mechanism 4 and a blanking component 5. The installation cover plate 3 is installed on the sewage treatment container, the feeding mechanism 4 is installed on the installation cover plate 3, the material receiving box 1 and the liquid supply pump 2 are both installed in the feeding mechanism 4, and the blanking component 5 is installed on the feeding mechanism 4.

[0022] In this embodiment, the feeding mechanism 4 includes a driving motor 301, a guiding plate 302, and a spiral conveying roller 303. The driving motor 301 is installed on the mounting cover plate 3 through a positioning frame 304. A rotating rod 305 is installed at the output end of the driving motor 301. A gear 306 is installed at the lower end of the rotating rod 305. A shifting rod 307 is fixedly installed in the middle of the positioning frame 304. Symmetrically arranged tooth discs 308 are installed at the lower part of the positioning frame 304. The tooth discs 308 are meshed with the gear 306. The guiding plate 302 is rotatably installed at the upper part of the positioning frame 304. The material receiving box 1 is installed at the upper part of the guiding plate 302. The spiral conveying roller 303 is fixedly installed at the back of the tooth disc 308 on one side close to the guiding plate 302. The other end of the spiral conveying roller 303 is rotatably installed on the blanking component 5. Both sides of the positioning frame 304 are movably connected with a "C"-shaped member 310 through springs 309. A plurality of evenly distributed liquid spraying heads 311 are fixedly installed at the back of the tooth disc 308 on the side far from the guiding plate 302. The liquid supply pump 2 is installed on the positioning frame 304 through an inclined plate 312. The liquid supply pump 2 is communicated with the plurality of liquid spraying heads 311.

[0023] It should be noted that the blanking component 5 includes a movable plate 41 and a blanking box 42. There are two movable plates 41 which are slidably arranged on the positioning frame 304. The movable plate 41 is also fixedly arranged at the end of the "C"-shaped member 310. The movable plate 41 cooperates with the inclined plate 312 at the lower end. The blanking box 42 is fixedly installed on the positioning frame 304 and is placed directly below the guiding plate 302. The upper end of the blanking box 42 cooperates with the spiral conveying roller 303. A liquid inlet 43 is opened at the side end of the blanking box 42. A plurality of evenly distributed blanking holes 44 are also opened at the lower end of the blanking box 42.

[0024] In this embodiment, the shifting rod 307 cooperates with the back of the guiding plate 302 and the upper part of the "C"-shaped member 310 in the horizontal direction.

[0025] In this embodiment, the apertures of the plurality of blanking holes 44 gradually become smaller along the length direction of the blanking box 42, and the aperture of the blanking hole 44 close to the inclined plate 312 is the largest.

[0026] Working process and principle: During the use of the present invention, first start the driving motor 301 so that its output end drives the rotating rod 305 to rotate. During the rotation of the rotating rod 305, the end thereof will drive the gear 306 to rotate, and then drive the two tooth discs 308 meshed with it on both sides to rotate synchronously and in opposite directions. The solid alkali source treatment agent in the material receiving box 1 falls into the blanking box 42 along the guiding plate 302;

[0027] The rotation of the screw conveyor roller 303 causes the solid alkali source treatment agent to be dispersed and spread in each drop hole 44, while the rotation of the rotating rod 305 will also drive the central lever 307 to rotate, which in turn causes the guide plate 302 to swing, so that the solid alkali source treatment agent is evenly distributed in the drop box 42, and the solid alkali source treatment agent is fully replenished in the sewage, resulting in more thorough treatment.

[0028] To prevent the solid alkali source treatment agent from being blocked by falling preferentially to the discharge hole 44 near the inclined plate 312 due to its own weight, several discharge holes 44 are arranged with gradually decreasing diameters along the length of the discharge box 42, and the discharge hole 44 near the inclined plate 312 has the largest diameter. At the same time, the rotation of the lever 307 will also cause the "U"-shaped part 310 to slide on the positioning frame 304. With the elasticity of the spring 309, the "U"-shaped part 310 slides back and forth on the positioning frame 304.

[0029] Under the pumping force of the liquid supply pump 2, the high-concentration liquid treatment agent that is ejected from the rotating spray head 311 enters the inlet 43 at an angle along the inclined plate 312, washing the solid alkali source treatment agent falling into each drop hole 44, so that the solid alkali source treatment agent and the high-concentration liquid treatment agent are mixed quantitatively first.

[0030] Based on the above, the present invention provides a feeding mechanism 4 and a dropping assembly 5 on the mounting cover plate 3. The output end of the drive motor 301 drives the rotating rod 305 to rotate, and the end of the rod drives the gear discs 308 on both sides to rotate synchronously in opposite directions through the gear 306. The solid alkali source treatment agent in the receiving box 1 falls into the dropping box 42 along the guide plate 302. The rotation of the spiral conveying roller 303 causes the solid alkali source treatment agent to be dispersed and spread in each dropping hole 44. The rotation of the rotating rod 305 also drives the lever 307 in the middle to rotate, thereby causing the guide plate 302 to swing, so that the solid alkali source treatment agent is evenly distributed in the dropping box 42. The solid alkali source treatment agent is fully replenished in the sewage, and the treatment is more thorough.

[0031] The rotation of lever 307 also causes the "U"-shaped part 310 to slide on the positioning frame 304. Combined with the elasticity of spring 309, the "U"-shaped part 310 slides back and forth on the positioning frame 304. The high-concentration liquid treatment agent ejected from the rotating spray head 311 flows down the inclined plate 312 into the inlet 43, rinsing the solid alkali source treatment agent falling into each discharge hole 44. This not only prevents the solid alkali source treatment agent from clogging the discharge hole 44, but also ensures that the solid alkali source treatment agent and the high-concentration liquid treatment agent are mixed quantitatively first, preventing impurities and flocculants from encapsulating the solid alkali source treatment agent after it enters the sewage. The dispersed solid alkali source treatment agent is evenly diffused in the sewage.

[0032] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this invention or its equivalents are included in this invention.
