Description

Technical Field

[0001] This utility model relates to the technical field of flocculant mixing equipment, specifically a flocculant mixing device. Background Technology

[0002] The existing flocculant preparation system used in coal preparation plants has several problems. First, the underground water source is unstable and contains many impurities, resulting in unsatisfactory flocculant mixing and preparation effects. The flocculant preparation system cannot efficiently and accurately treat coal slurry water, leading to the discharge of untreated wastewater. Second, the high impurity content of the water source leads to incomplete utilization of the flocculant. Excess flocculant adheres to the inner wall of the slurry storage tank, causing agent accumulation. This means that some of the effective components of the flocculant used each time are not fully utilized due to deposition, thus adhering to the inner wall and wasting the agent. To ensure effective treatment of coal slurry water, the amount of flocculant added needs to be increased. However, inaccurate addition leads to excessive or insufficient dosage, which in turn affects the treatment effect and cost control. It also causes blockage of the slurry storage tank and conveying pipeline, affecting the normal operation of the system. When the sediment continues to accumulate, it will cause serious blockage at the outlet of the slurry storage tank or in the pipeline. Utility Model Content

[0003] The purpose of this invention is to provide a flocculant mixing device to solve the problems caused by unstable underground water sources and a large number of impurities, which lead to unsatisfactory flocculant mixing and preparation effects, and the inability of the flocculant preparation system to efficiently and accurately treat coal slurry water, resulting in the discharge of uncleaned wastewater. Secondly, due to the large number of impurities in the water source, the flocculant is not fully utilized, and the excess flocculant adheres to the inner wall of the slurry storage tank, causing agent accumulation. At the same time, it also causes blockage of the slurry storage tank and the conveying pipeline, affecting the normal operation of the system. When the sediment continues to accumulate, it will cause serious blockage at the outlet of the slurry storage tank or in the pipeline.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a flocculant stirring device, comprising a water tank, a filter cloth, a cleaning device installed inside the water tank, and a stirring cylinder. The top of the water tank is connected to a water source via a pipeline, on which a solenoid valve is installed. A protrusion is provided on the inner wall of the water tank, and a filter cloth shell is placed on the protrusion. A filter cloth is connected to the filter cloth shell, and a cleaning device is provided at the top of the filter cloth and connected to the water tank. A heating zone is formed between the bottom end of the filter cloth and the bottom end of the inner wall of the water tank, and the heating zone is equipped with a heating plate and a stirring cylinder. The device includes a thermostat connected to a power source. A water outlet is located at the bottom of the water tank and connected to a pipe at the top of the mixing drum. The cleaning device comprises a lead screw, a slider, and a scraper. A through hole is located at the front of the water tank, through which the lead screw is inserted. The lead screw passes through the through hole, with its bottom end contacting the inner wall of the water tank. An adjusting handwheel is connected to the top of the lead screw. A slider engages with the lead screw, and the slider slides along the lead screw. A horizontally positioned scraper is connected to the bottom of the slider, and the scraper fits tightly against the filter cloth. The width of the scraper corresponds to the width of the filter cloth.

[0005] The mixing drum has a flocculant addition port at the top and a liquid outlet at the bottom. A one-way valve is installed on the liquid outlet pipe. An impeller is connected inside the mixing drum. The input end of the impeller is connected to the output end of the drive motor, and the drive motor is located at the bottom of the mixing drum. A vertically erected cleaning plate is connected to the end of the impeller blades away from the rotating shaft. The cleaning plate abuts against the inner wall of the mixing drum. A guide plate is connected to the top. The other end of the guide plate is set in a groove opened at the top of the mixing drum and rotates to fit the mixing drum.

[0006] Preferably, it also includes a pressing device, symmetrically arranged on the left and right sides of the filter cloth shell and staggered from the cleaning device. It includes a support plate, a pressing block, a torsion spring, and a limiting block. The pressing block is L-shaped, with its bottom vertical end abutting against the top of the filter cloth shell. The horizontal end away from the filter cloth shell is connected to a rotating shaft, and the connection end with the rotating shaft is concave. The two ends of the rotating shaft are connected to the support plate, which is connected to the boss. The end of the support plate away from the filter cloth shell is provided with a limiting block. A torsion spring is sleeved on the rotating shaft and is located inside the concave end of the pressing block. One end of the torsion spring abuts against the top of the pressing block, and the other end abuts against the limiting block.

[0007] Preferably, it also includes a protective shell, which is a rectangular hollow shell mounted on the lead screw. The protective shell is connected to the inner walls of the front and rear ends of the water tank, and a guide groove is provided at its bottom end. The inner wall of the protective shell abuts against the slider, and the guide groove is provided with a connection point between the slider and the scraper.

[0008] Preferably, the contact ends of the lead screw and the water tank are respectively provided with bearing seats.

[0009] Preferably, the water tank is provided with a cleaning groove, which is flush with the top of the filter cloth shell.

[0010] Preferably, the guide plate is connected to the contact end of the chute with a roller.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The filter cloth shell is embedded in a protrusion inside the water tank. Each end of the filter cloth shell has a clamping device. During installation, rotating the clamping block rotates a torsion spring, one end of which contacts a limiting block, generating a resetting force. The filter cloth shell is then accurately placed inside the protrusion, and the clamping block is released to press the two ends of the filter cloth shell together, ensuring a secure installation. A cleaning device is also provided on the filter cloth for periodic cleaning of the filter surface, ensuring the filter cloth's high-efficiency filtration performance.

[0013] After water enters the water tank through pipes, it first passes through a filter cloth, which effectively removes impurities from the water source. The filtered water then flows into the heating zone, where it is heated by a heating plate for subsequent treatment or use, enhancing the performance of reagent preparation. When excessive impurities accumulate on the filter cloth surface, a rotating screw moves a slider, which in turn drives a scraper mounted on the filter cloth to clean the surface. The scraper pushes the accumulated impurities into a cleaning tank for periodic discharge, ensuring the filter cloth remains clean and the filtration effect is not affected.

[0014] In addition, vertically mounted scrapers are installed on the impeller of the mixing drum. These scrapers rotate synchronously with the impeller, effectively scraping off the chemicals adhering to the inner wall of the mixing drum. This prevents waste and accumulation of chemicals, which could lead to blockages and incomplete preparation. Simultaneously, the scraper's movement helps to thoroughly mix the materials within the mixing drum, ensuring uniform mixing of chemicals and water, improving mixing efficiency, and preventing chemical accumulation on the inner wall of the mixing drum, thereby enhancing the system's treatment effect.

[0015] Through this series of design and operation steps, the system can effectively avoid chemical waste, ensure efficient and stable water treatment processes, and reduce operational difficulty and maintenance costs. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] Example 1: Please refer to Figure 1-6This utility model provides an embodiment of a flocculant stirring device, including a water tank 1, a filter cloth 101, a cleaning device 3 installed inside the water tank 1, and a stirring drum 4. The top of the water tank 1 is connected to a water source via a pipeline, and a solenoid valve 2 is installed on the pipeline. The water tank 1, as the main body of the entire device, is used to contain and treat the water source and provide a space for filtering impurities and heating the filtered water. The solenoid valve 2 controls the inflow and outflow of water in the water tank 1. The flow rate of water entering the water tank 1 can be controlled by controlling the opening and closing of the solenoid valve 2. A protrusion is provided on the inner wall of the water tank 1, and a filter cloth shell is placed on the protrusion. The filter cloth 101 is connected to the filter cloth shell. The top of the filter cloth 101 and the filter cloth shell are connected to each other. The filter cloth 101, flush with the water source, filters impurities from the water itself as it enters the water tank 1, cleaning the water. It effectively removes particulate matter, ensuring water purification and improving the preparation effect. The filter cloth shell supports the filter cloth 101, ensuring it doesn't deform or fall off. It's also mounted on a raised platform for easy replacement. A cleaning device 3 is located at the top of the filter cloth 101, used to periodically clean accumulated material to prevent clogging and reduced filtration efficiency. Connected to the water tank 1, the bottom of the filter cloth 101 and the bottom of the inner wall of the water tank 1 form a heating zone. This zone includes a heating plate and a temperature controller, and is connected to a power source. Typically, low-temperature water... This can easily lead to flocculant precipitation. Heated water can maintain a certain temperature, reducing precipitation and thus avoiding pipe blockage and waste of flocculant. A water outlet is located at the bottom of the water tank 1, connected to the top of the mixing drum 4 via a pipe. A one-way valve is installed on the pipe. The cleaning device 3 includes a screw 301, a slider 302, and a scraper 303. A through hole is located at the front of the water tank 1, into which the screw 301 is inserted. The screw 301 drives the slider 302 to move, simultaneously driving the scraper 303 to clean debris from the surface of the filter cloth 101. The screw 301 passes through the through hole, its bottom end abutting against the inner wall of the water tank 1, and its top end is connected to an adjusting handwheel for manually driving the screw 301. The screw 301 rotates, providing drive. A slider 302 engages with the screw 301. The internal thread of the slider 302 mates with the external thread of the screw 301. When the screw 301 rotates, its external thread rotates, and simultaneously, the internal and external threads of the slider 302 engage, causing it to move. The slider 302 slidably engages with the screw 301. A horizontally positioned scraper 303 is connected to the bottom end of the slider 302. The bottom end of the scraper 303 is in contact with the top end of the filter cloth 101. The scraper 303 is moved synchronously with the slider 302 to clean the surface of the filter cloth 101. The scraper 303 is in close contact with the filter cloth 101, and its width is set to correspond to the width of the filter cloth 101.

[0028] The lead screw 301 and the water tank 1 are respectively provided with bearing seats. The bearing seats provide support for the lead screw 301 and facilitate its rotation, while reducing friction.

[0029] The water tank 1 is provided with a cleaning groove 102, which is flush with the top of the filter cloth shell. The cleaning groove 102 allows the filter cloth 101 to be discharged after the scraper 303 cleans the surface of the filter cloth 101. At the same time, being flush with the top of the filter cloth shell makes it easier for the scraper 303 to push away and discharge the debris.

[0030] The top of the mixing drum 4 has a flocculant addition port 5, which is used for manual addition of flocculant into the mixing drum 4. The impeller 401 then rotates to stir the mixture. The bottom has a liquid outlet 6, and a one-way valve is installed on the outlet pipe to ensure one-way flow of the prepared reagent. The impeller 401 is connected inside the mixing drum 4. Driven by the drive motor 7, the impeller 401 rotates, thoroughly mixing the water and reagent. The input end of the impeller 401 is connected to the output end of the drive motor 7, which is located at the bottom of the mixing drum 4. A vertically erected cleaning plate 402 is connected to the end of the impeller 401 blades furthest from the rotating shaft. The cleaning plate 402 is used to clean the agent on the inner wall of the mixing drum 4 during stirring, so as to prevent the agent from being insufficiently reacted and adhering to the inner wall of the mixing drum 4, causing accumulation. The cleaning plate 402 abuts against the inner wall of the mixing drum 4, and a guide plate 404 is connected to the top. The guide plate 404 and the contact end of the slide groove 403 are connected to rollers. The guide plate 404 ensures the stability of the movement trajectory of the cleaning plate 402, while the slide groove 403 and the rollers ensure that the guide plate 404 can slide smoothly in the mixing drum 4, and at the same time provide positioning support for the cleaning plate 402. The other end of the guide plate 404 is set in the slide groove 403 opened at the top of the mixing drum 4 and rotates to engage with the mixing drum 4.

[0031] In use, the filter cloth shell is first placed on the raised platform, and then the water source pipe is placed on the water tank 1. When the water source enters, it is first filtered through the filter cloth 101. Then the filtered water passes through the heating plate and temperature controller in the heating zone to be heated and kept within the fully prepared temperature. Then it enters the stirring drum 4. The drive motor 7 is started to drive the impeller 401 to rotate. When the impeller 401 rotates, it drives the cleaning plate 402 to rotate synchronously. At the same time, the guide plate 404 connected to the top of the cleaning plate 402 slides in the slide groove 403 to further support and position the cleaning plate 402. The cleaning plate 402 scrapes off the unreacted agent adhering to the inner wall of the stirring drum 4 and stirs it.

[0032] Example 2: Please refer to Figure 2-3 Based on Example 1, it also has the following structure:

[0033] It also includes a pressing device, symmetrically arranged on the left and right sides of the filter cloth shell and staggered from the cleaning device 3. This device includes a support plate, a pressing block 103, a torsion spring 104, and a limiting block 105. The pressing block 103 is L-shaped and applies pressure to the filter cloth shell to ensure it fits tightly inside the water tank 1, thereby improving filtration efficiency. The L-shaped design allows the pressing block 103 to firmly contact the top of the filter cloth shell at its vertical end, while the horizontal end is connected to other components via a rotating shaft, ensuring even pressure distribution. The bottom of the vertical end abuts against the top of the filter cloth shell, and the horizontal end away from the filter cloth shell is connected to a rotating shaft with a concave connection. Support plates are connected to the two ends of the rotating shaft, and the support plates are connected to the protrusions. A limiting block 105 is provided at the end of the support plate away from the filter cloth shell. A torsion spring 104 is fitted on the rotating shaft, providing elastic restoring force to help... The clamping block 103 maintains a certain pressure to ensure that the filter cloth shell is in a stable clamped state for a long time. The two contact ends of the torsion spring 104 contact the clamping block 103 and the limiting block 105 respectively, thereby generating a clamping force. It is set in the concave end of the clamping block 103, and the concave end provides a placement range for the torsion spring 104. One end of the torsion spring 104 abuts against the top of the clamping block 103. The limiting block 105 is used to limit the range of motion of the clamping block 103 and works in conjunction with the torsion spring 104 to provide force to the clamping block 103. The other end abuts against the limiting block 105. During installation, the clamping block 103 is rotated first, which then drives the torsion spring 104 to rotate. At the same time, because the other end of the torsion spring 104 abuts against the limiting block 105, a reset force is generated. After the filter screen shell is installed, the clamping block 103 is released. Through the force of the torsion spring 104, the bottom of the vertical end of the clamping block 103 is pressed against the top of the filter screen shell.

[0034] Example 3: Please refer to Figure 2 Based on Example 1, it also has the following structure:

[0035] It also includes a protective shell 304, which protects the internal screw 301 and slider 302 system, reducing water splashing onto the screw 301 when filtered by the filter cloth 101. The rectangular hollow structure of the protective shell 304 provides sufficient space to accommodate the slider 302, screw 301 and related connecting parts, increasing the durability and stability of the equipment. The protective shell 304 is a rectangular hollow shell, set on the screw 301. The protective shell 304 is connected to the inner walls of the front and rear ends of the water tank 1, and a guide groove is opened at its bottom end. The inner wall of the protective shell 304 abuts against the slider 302. The guide groove has a connection point between the slider 302 and the scraper 303. The guide groove is used to assist in positioning the connection point and reduce water entering the interior of the protective shell 304.
