Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a flocculant particle dissolution device for wastewater treatment systems. Background Technology

[0002] In wastewater treatment systems, flocculants are generally used to coagulate and flocculate dispersed particles in wastewater into aggregates. Currently, the flocculants used in wastewater treatment systems are flocculant solutions. These solutions need to be prepared using a flocculant particle dissolving device before use, and the quality of the flocculant solution preparation directly affects the subsequent wastewater treatment effect.

[0003] Publication No. CN218553696U discloses a flocculant particle dissolution device for wastewater treatment systems. This device uses a stirring unit to mix water and flocculant to obtain a fully mixed flocculant solution. It solves the technical problems in the prior art where uneven flocculant mixing and low water temperature lead to low flocculant dissolution efficiency, causing flocculants to easily form clumps and agglomerate. However, this patent still has the following problems in actual use:

[0004] This device uses a stirring unit to mix water and flocculant to obtain a fully mixed flocculant solution. It solves the technical problems in the prior art where uneven mixing of flocculant and low water temperature lead to low flocculant dissolution efficiency, causing flocculant to easily form clumps and agglomerate. Since most flocculants are highly hygroscopic, they easily absorb moisture from the air, causing the particle surface to stick together, which may lead to flocculant particles agglomerating. Because the prior art does not have a function to break up flocculant particles, it may cause flocculant particles to clog the feed box, causing inconvenience to the operators.

[0005] A flocculant particle dissolution device for wastewater treatment systems is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a flocculant particle dissolving device for wastewater treatment systems, which solves the problem mentioned in the background art where water and flocculant are mixed and stirred by a stirring unit to obtain a fully mixed flocculant solution. This invention addresses the technical problems in the prior art where uneven stirring of the flocculant and low water temperature lead to low flocculant dissolution efficiency, resulting in flocculant easily forming clumps and agglomerates. Since most flocculants are highly hygroscopic and easily absorb moisture from the air, the particle surface adheres, which may lead to flocculant particle agglomeration. Because the prior art does not have a flocculant particle agglomeration breaking function, it may lead to flocculant particle agglomeration clogging the feed box.

[0008] The feeding mechanism includes a frame fixedly installed on one side of the top of the dissolving tank, a box fixedly installed on the top of the frame, and connecting pipes symmetrically fixedly installed between the frame and the dissolving tank. A fixed box is fixedly connected to the top of the box, and a filter screen is embedded in the lower interior of the box. A stirring rod is rotatably connected between the fixed box and the box, and pulverizing blades are symmetrically fixedly installed on the outside of the stirring rod. A rotating rod is rotatably connected to one side of the fixed box, and a first conical tooth is fixedly installed on the top outer side of the stirring rod. A second conical tooth is fixedly installed at one end of the rotating rod, and a servo motor is fixedly installed on the top of the stirring rod. A strip box is fixedly installed inside the frame, and a rotating shaft is rotatably connected between the strip box and the frame. A sprocket is fixedly installed on the outside of one end of the rotating rod and the rotating shaft, and a chain is meshed between the outside of the sprocket. A rotating disk is rotatably connected to the bottom inside the frame.

[0009] Preferably, the inside of the strip box is rotatably connected to a connecting rod, and the outer side of the rotating shaft near the strip box is welded with worm gear teeth. A worm wheel is fixedly installed on the top outer side of the connecting rod, and the bottom of the connecting rod is fixedly connected to the top of the rotating disk. The two ends of the rotating disk are symmetrically provided with slots.

[0010] Preferably, the dustproof component includes a connecting frame fixedly installed on one side of the top of the housing, and a feeding frame fixedly installed on the top of the connecting frame. A rotating plate is hinged to one side of the top of the feeding frame. A limit box is fixedly connected inside one end of the rotating plate. A fixing tube is fixedly installed inside one side of the limit box. A pull rod is slidably connected inside the fixing tube. A retraction spring is sleeved on the outside of the pull rod. A pull plate is fixedly installed at the end of the pull rod away from the fixing tube. Insert blocks are welded to the side of the pull plate away from the pull rod. Slots are opened on the top side of the feeding frame. Insert blocks are inserted into the slots.

[0011] Preferably, sliding sleeves are symmetrically fixedly installed on both sides of the fixed tube, and a support rod is slidably connected inside the sliding sleeve. A baffle is fixedly connected to one end of the support rod, and the end of the support rod away from the baffle is fixedly connected to the pull plate.

[0012] Preferably, a brush plate is fixedly installed at the bottom of the stirring rod, and a limiting sleeve is rotatably connected to the outside of the rotating rod, and the bottom of the limiting sleeve is fixedly connected to the top of the box.

[0013] Preferably, the first conical tooth and the second conical tooth are engaged in a meshing connection.

[0014] Preferably, the worm teeth are meshed with the worm wheel.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: A flocculant particle dissolving device for a wastewater treatment system is described below: A servo motor drives a stirring rod to rotate, which in turn drives multiple sets of crushing blades to crush agglomerated flocculant particles. The rotation of the stirring rod drives the rotation of a first conical tooth, which in turn drives the rotation of a second conical tooth. Through the cooperation between the sprocket and the chain, the rotating shaft rotates, the worm gear drives the worm wheel, the connecting rod drives the rotation of a rotating disk, and the rotating disk drives the rotation of the slot. This achieves the effect of rapidly crushing agglomerated flocculant particles, thereby enabling… It can crush larger particles into finer particles, significantly improving the dissolution efficiency of flocculants and reducing the risk of feed interruption caused by large particles clogging the filter screen. The continuous intermittent feed design of flocculants avoids local concentration overload during flocculant dissolution, thus improving the dissolution efficiency of flocculants. When the operator pulls the lever and slides it inside the fixed tube, the movement of the lever drives the movement of the pull plate. At this time, the contraction spring contracts, and the return property of the contraction spring allows multiple sets of inserts to be inserted into the slots, thereby achieving the effect of quickly fixing and limiting the rotating plate. This effectively prevents dust from entering the equipment when it is not in use, thus greatly improving the flexibility of the device during use.

[0016] 1. The flocculant granules are poured into the chamber through the connecting frame and feed frame by the operator. The filter screen filters the flocculant granules. Then, the operator starts the servo motor to rotate the stirring rod. The rotation of the stirring rod drives multiple sets of crushing blades to break up any agglomerated flocculant granules. The filtered flocculant granules fall into the chamber. The rotation of the stirring rod drives the first conical tooth to rotate, which in turn drives the second conical tooth to rotate. The second conical tooth then drives the rotating rod, which in turn drives the sprocket. Through the interaction between the sprocket and the chain, the rotating shaft rotates. The rotating shaft then drives the worm gear, which in turn drives the worm wheel. The worm wheel then drives the connecting rod. The rotating connecting rod drives the rotating disk, which in turn drives the rotating slot. When the slot aligns with the connecting pipe, flocculant particles are discharged into the dissolution tank through the connecting pipe. When the slot moves away from the connecting pipe, the bottom of the frame seals the slot, enabling continuous intermittent feeding of flocculant particles. This allows for rapid crushing of agglomerated flocculant particles, breaking larger particles into smaller ones, significantly improving flocculant particle dissolution efficiency, and reducing the risk of feeding interruption due to large particles clogging the filter screen. The continuous intermittent feeding design avoids local concentration overload during flocculant particle dissolution, improving flocculant particle dissolution efficiency and providing convenience for operators.

[0017] 2. The operator rotates the rotating plate at the top of the feeding frame, bringing it into contact with the top of the frame. The operator then pulls the lever, causing it to slide inside the fixed tube. This movement of the lever moves the pulling plate, causing the spring to contract. The operator then releases the lever, and the spring's restoring property allows multiple sets of inserts to engage with the slots, achieving a quick and secure fixation of the rotating plate. This effectively prevents dust from entering the equipment when not in use, greatly improving the flexibility of the device and providing convenience for operators. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides a technical solution: a flocculant particle dissolving device for a wastewater treatment system, comprising a dissolving tank 1, an inlet pipe 101 provided on one side of the top of the dissolving tank 1, and a discharge pipe 102 provided on one side of the bottom of the dissolving tank 1; a feeding mechanism 2 provided on one side of the top of the dissolving tank 1, and a dustproof component 3 provided inside the feeding mechanism 2.

[0026] The feeding mechanism 2 includes a frame 201 fixedly installed on one side of the top of the dissolving tank 1, and a box 202 fixedly installed on the top of the frame 201. Connecting pipes 203 are symmetrically fixedly installed between the frame 201 and the dissolving tank 1. A fixing box 204 is fixedly connected to the top of the box 202. A filter screen 205 is embedded in the lower interior of the box 202. A stirring rod 206 is rotatably connected between the fixing box 204 and the box 202.

A connecting rod 217 is rotatably connected to the inside of the strip box 212. Worm teeth 218 are welded to the outer side of the shaft 213 near the strip box 212. A worm wheel 219 is fixedly mounted on the top outer side of the connecting rod 217, and the worm teeth 218 and the worm wheel 219 mesh with each other. The bottom of the connecting rod 217 is connected to the rotating disk 216. The tops of the 16 are fixedly connected, and the two ends of the rotating disk 216 are symmetrically provided with slots 220, which can quickly crush the flocculant particles into small particles, thereby significantly improving the flocculant particle dissolution efficiency. At the same time, it reduces the risk of material feeding interruption caused by large particles clogging the filter screen 205. Through the design of continuous intermittent feeding of flocculant particles, local concentration overload is avoided when flocculant particles are dissolved, improving the flocculant particle dissolution efficiency and bringing convenience to the staff when using it.

[0027] A brush plate 221 is fixedly installed at the bottom of the stirring rod 206, and a limiting sleeve 222 is rotatably connected to the outside of the rotating rod 208. The bottom of the limiting sleeve 222 is fixedly connected to the top of the box 202. The rotation of the stirring rod 206 drives the rotation of the brush plate 221. The rotation of the brush plate 221 drives the surface bristles to clean the filter screen 205, thereby effectively reducing the probability of filter screen 205 clogging and improving the smoothness of flocculant particle feeding. The design of the limiting sleeve 222 makes the rotation of the rotating rod 208 more stable.

[0028] The dustproof component 3 includes a connecting frame 301 fixedly installed on one side of the top of the housing 202, and a feeding frame 302 fixedly installed on the top of the connecting frame 301. A rotating plate 303 is hinged to one side of the top of the feeding frame 302. A limit box 304 is fixedly connected inside one end of the rotating plate 303. A fixing tube 305 is fixedly installed inside one side of the limit box 304. A pull rod 306 is slidably connected inside the fixing tube 305.

A pull plate 308 is fixedly installed at the end of 306 away from the fixed tube 305, and a plug block 309 is welded on the side of the pull plate 308 away from the pull rod 306. A slot 310 is opened on the top side of the feed frame 302, and the plug block 309 is inserted into the slot 310. This can achieve the effect of quickly fixing the limiting rotating plate 303, thereby effectively preventing the phenomenon of dust entering the equipment when it is not in use. This can greatly improve the flexibility of the device during use and bring convenience to the staff.

[0029] Sliding sleeves 311 are symmetrically fixed on both sides of the fixed tube 305, and a support rod 312 is slidably connected inside the sliding sleeve 311. A baffle 313 is fixedly connected to one end of the support rod 312, and the end of the support rod 312 away from the baffle 313 is fixedly connected to the pull plate 308. The movement of the pull plate 308 drives the two sets of support rods 312 to slide inside the sliding sleeve 311. At this time, the baffle 313 prevents the support rod 312 from separating from the sliding sleeve 311, thereby achieving the effect of guiding the pull plate 308 and greatly improving the connection stability between the insert block 309 and the slot 310.

[0030] Working principle: Before using this flocculant granule dissolving device for wastewater treatment systems, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5As shown, the flocculant particles are poured into the box 202 through the connecting frame 301 and the feeding frame 302 by the operator. At this time, the filter screen 205 filters the flocculant particles. Then, the operator starts the servo motor 211 to drive the stirring rod 206 to rotate. The rotation of the stirring rod 206 drives multiple sets of crushing blades 207 to crush the flocculant particles that have clumped together. At this time, the filtered flocculant particles fall into the box 201. The rotation of the stirring rod 206 drives the first conical tooth 209 to rotate. The rotation of the first conical tooth 209 drives the... The rotation of the second conical tooth 210 drives the rotation of the rotating rod 208, which in turn drives the rotation of the sprocket 214. Through the interaction between the sprocket 214 and the chain 215, the rotating shaft 213 is driven to rotate. The rotation of the shaft 213 drives the rotation of the worm gear 218, which in turn drives the rotation of the worm wheel 219. The rotation of the worm wheel 219 drives the rotation of the connecting rod 217, which in turn drives the rotation of the rotating disk 216. The rotation of the rotating disk 216 then drives... The rotation of the slot 220 allows flocculant particles to be discharged into the dissolution tank 1 through the connecting pipe 203 when the slot 220 aligns with the connecting pipe 203. When the slot 220 moves away from the connecting pipe 203, the bottom of the frame 201 seals the slot 220, achieving continuous intermittent feeding of flocculant particles. This enables rapid crushing of agglomerated flocculant particles, breaking larger particles into smaller ones, significantly improving the dissolution efficiency of the flocculant particles, and reducing the risk of large particles clogging the filter screen 205. To mitigate the risk of interrupted feeding, the design of continuous intermittent feeding of flocculant particles avoids local concentration overload during flocculant particle dissolution, improves flocculant particle dissolution efficiency, and provides convenience for operators. The rotation of the stirring rod 206 drives the rotation of the brush plate 221, which in turn drives the surface bristles to clean the filter screen 205, thereby effectively reducing the probability of filter screen 205 clogging and improving the smoothness of flocculant particle feeding. The design of the limiting sleeve 222 makes the rotation of the rotating rod 208 more stable.

[0031] The operator rotates the rotating plate 303 on top of the feeding frame 302, at which point the rotating plate 303 is in contact with the top of the feeding frame 302. Then, the operator pulls the pull rod 306, which slides inside the fixed tube 305. The movement of the pull rod 306 causes the pull plate 308 to move, and the contraction spring 307 contracts. The operator then releases the pull rod 306, and the reset property of the contraction spring 307 allows multiple sets of insert blocks 309 to be inserted into the slots 310, thereby achieving the effect of quickly fixing and limiting the rotating plate 303. This effectively prevents dust from entering the equipment when it is not in use, greatly improving the flexibility of the device and providing convenience for the operator. The movement of the pull plate 308 causes two sets of support rods 312 to slide inside the sliding sleeve 311. At this time, the baffle 313 prevents the support rods 312 from separating from the sliding sleeve 311, thereby guiding the pull plate 308 and greatly improving the connection stability between the insert blocks 309 and the slots 310.

[0032] The existing technology, including the dissolving tank 1, the inlet pipe 101, and the outlet pipe 102, discloses a flocculant particle dissolving device for a wastewater treatment system. The device used in this device will not be described in detail here.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
