Description

Technical Field

[0001] This utility model relates to the field of aluminum sulfate water purification agent preparation technology, and in particular to an apparatus for preparing aluminum sulfate water purification agent. Background Technology

[0002] Aluminum sulfate is a commonly used water purification agent and is widely used in the field of water treatment. Its preparation process requires drying of wet aluminum sulfate crystals to remove moisture and ensure product purity and performance. Therefore, the drying process is a key step in the preparation of aluminum sulfate water purification agents.

[0003] Existing technologies for drying aluminum sulfate often employ simple drying equipment, such as ordinary drying ovens and open drying tanks. These devices have significant technical drawbacks: First, they have low automation, requiring frequent manual monitoring of drying temperature, turning of materials, and control of discharge. This not only consumes a large amount of labor but is also prone to temperature fluctuations due to human error (e.g., aluminum sulfate is prone to thermal decomposition above 80℃, and drying efficiency is low below 60℃), affecting product quality stability. Second, they have poor material handling. Traditional equipment lacks a targeted turning structure, causing wet aluminum sulfate crystals to easily adhere to the inner wall of the equipment, resulting in uneven heating and incomplete drying of some materials. At the same time, the open or simple exhaust design cannot remove moisture in time, further reducing drying efficiency. Third, they are not safe or environmentally friendly. Manual operation involves contact with high-temperature equipment, posing safety hazards, and the direct discharge of untreated moisture can easily create a damp local environment, which does not meet the requirements of modern production.

[0004] Therefore, a device for preparing aluminum sulfate water purification agent is proposed. Utility Model Content

[0020] 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.

[0021] See Figure 1-7 As shown in the figure, the apparatus for preparing aluminum sulfate water purification agent in this embodiment includes a drying cylinder 1. Inside the drying cylinder 1, there is a turning component 2 for turning the material. At the lower end of the drying cylinder 1, there is a baffle component 3 for controlling the discharge of material. At the lower end of the outer side of the drying cylinder 1, there is a temperature sensor 4 for monitoring the temperature inside the cylinder. At the outer side of the drying cylinder 1, there are hot air components 5 for introducing hot air into the cylinder in a neat and uniform manner along the circumference. At the upper end of the outer side of the drying cylinder 1, there is an exhaust pipe 6 for discharging moisture from the cylinder. At the outer side of the drying cylinder 1, there is a bracket 7 for supporting the entire device. On one side of the bracket 7, there is a control box 8 for controlling the operation of each component. The control box 8 is electrically connected to the turning component 2, the baffle component 3, the temperature sensor 4, the hot air component 5, and the exhaust pipe 6 to realize the automated control of the device.

[0022] Specifically, the drying cylinder 1 serves as the core of the device, containing and drying space, and its components have clearly defined functions.

[0023] The core function of the turning component 2 is to turn the material over, ensuring that the wet aluminum sulfate crystals are heated evenly and preventing them from sticking together.

[0024] The baffle assembly 3 is used to control the opening and closing of the fan-shaped through hole on the bottom surface of the cylinder body 101, so as to realize the retention and discharge control of materials and ensure sealing performance.

[0025] The core function of the hot air assembly 5 is to introduce hot air into the cylinder body 101 to provide heat for drying wet aluminum sulfate crystals.

[0026] The main function of the exhaust pipe 6 is to discharge the humid heat steam generated in the drying process inside the cylinder body 101, and maintain the dry environment inside the cylinder.

[0027] The bracket 7 is fixedly mounted on the outside of the drying cylinder 1, providing stable support for the entire aluminum sulfate water purification agent preparation device, ensuring that the device remains stable during operation, and preventing the device from shifting or tipping over due to vibration or other reasons.

[0028] The control box 8, as the control core of the device, is electrically connected to the main motor 201 of the turning assembly 2, the auxiliary motor 302 of the baffle assembly 3, the temperature sensor 4, the spiral heating tube of the hot air assembly 5, and the exhaust fan 601 of the exhaust pipe 6. On one hand, it receives real-time temperature data transmitted by the temperature sensor 4 and controls the heating power of the spiral heating tube in the spiral heating cylinder 502 according to the preset temperature range of 60-80℃, thus adjusting the hot air temperature. On the other hand, it controls the start / stop and speed of the main motor 201 to achieve proper turning of the material by the T-shaped shovel 204; it controls the start / stop and rotation direction of the auxiliary motor 302 to achieve the opening and closing of the fan-shaped baffle 303, controlling the timing of material discharge; simultaneously, it adjusts the exhaust rate of the exhaust fan 601 to optimize the moisture discharge effect, ultimately achieving automated control of the device and ensuring a stable and efficient drying process.

[0029] See appendix Figure 1-5 As shown, the drying cylinder 1 includes a cylinder body 101 for containing materials, a curved discharge trough 102 integrally formed with a fan-shaped through hole on the bottom surface of the cylinder body 101, and a feed hopper 103 integrally formed with a feed through hole on the top surface of the cylinder body 101. The cylinder body 101 is inclined downward, with the feed through hole on its top surface facing upward to facilitate feeding, and the fan-shaped through hole on its bottom surface facing downward to communicate with the curved discharge trough 102, ensuring that the materials can be smoothly discharged along the curved discharge trough 102. The cylinder body 101 is made of high-temperature resistant stainless steel, and its inner wall is smooth to reduce material adhesion.

[0030] Specifically, the main body 101 is made of high-temperature resistant stainless steel with a smooth inner wall, which can both accommodate wet aluminum sulfate crystals and reduce material adhesion. It is also inclined downwards and has a fan-shaped through hole on the bottom to guide the material discharge. The air inlet hole on the side wall is connected to the hot air component 5 to ensure the entry of hot air, while the exhaust hole on the top provides a channel for the discharge of moisture.

[0031] The curved discharge trough 102 corresponds to the fan-shaped through hole on the bottom surface of the cylinder body 101 and is integrally formed. When the fan-shaped baffle 303 is opened, the dried aluminum sulfate water purification agent can be discharged smoothly along it, avoiding material accumulation and blockage.

[0032] The feed hopper 103 corresponds to the feed through hole on the top surface of the cylinder body 101 and is integrally formed, which facilitates the pouring of wet aluminum sulfate crystals into the cylinder body 101 and realizes convenient material feeding.

[0033] See appendix Figure 1-7 As shown, the turning assembly 2 includes a main motor 201 fixedly mounted in a circular frame on the top surface of the cylinder body 101, a bearing 202 fixedly mounted in a circular groove at the lower end of the cylinder body 101, a rotating shaft 203 fixedly mounted at both ends between the output end of the main motor 201 and the inner ring of the bearing 202, and a plurality of T-shaped shovels 204 evenly distributed along the axial direction of the rotating shaft 203 and fixedly welded to the outside of the rotating shaft 203; the main motor 201 drives the rotating shaft 203 to rotate around the axis of the bearing 202, thereby driving the T-shaped shovels 204 to rotate synchronously; the lower end of the T-shaped shovels 204 is tightly fitted with the inner wall of the cylinder body 101, and the surface of the T-shaped shovels 204 is treated with an anti-corrosion coating to adapt to the characteristics of aluminum sulfate material.

[0034] Specifically, the main motor 201 is fixedly mounted in the circular frame on the top surface of the cylinder body 101, providing power to the tilting assembly 2, driving the rotating shaft 203 to rotate around the axis of the bearing 202, thereby driving the T-shaped shovel 204 to rotate synchronously.

[0035] The bearing 202 is fixedly assembled in the circular groove at the lower end of the inner body of the cylinder 101, which supports the rotating shaft 203, reduces the frictional resistance when the rotating shaft 203 rotates, and makes the rotating shaft 203 rotate more smoothly.

[0036] The two ends of the rotating shaft 203 are fixedly mounted between the output end of the main motor 201 and the inner ring of the bearing 202, respectively. As a power transmission component, it transmits the power of the main motor 201 to the T-shaped shovel 204, causing the T-shaped shovel 204 to rotate.

[0037] T-shaped shovels 204 are evenly distributed along the axial direction of the rotating shaft 203 and are fixedly welded to the outside of the rotating shaft 203. The lower end is tightly fitted to the inner wall of the cylinder body 101. When rotating, they can turn over the wet aluminum sulfate crystals inside the cylinder body 101 to prevent the material from sticking together and causing uneven heating. The surface is treated with an anti-corrosion coating to adapt to the characteristics of aluminum sulfate material and prevent it from being corroded and damaged.

[0038] See appendix Figure 1-7As shown, the baffle assembly 3 includes a motor outer frame 301 fixedly welded to the bottom surface of the cylinder body 101 near the center, an auxiliary motor 302 fixedly assembled inside the motor outer frame 301, a fan-shaped baffle 303 fixedly assembled at the output end of the auxiliary motor 302 and matching the fan-shaped through hole on the bottom surface of the cylinder body 101, and a silicone sealing strip 304 fixed to the edge of the fan-shaped baffle 303 by a high-temperature resistant adhesive. The auxiliary motor 302 can drive the fan-shaped baffle 303 to rotate around the axis of the output end. When the fan-shaped baffle 303 rotates to the blocking position, its top surface is tightly attached to the bottom surface of the cylinder body 101, and the silicone sealing strip 304 can fill the gap between the two, thereby achieving the sealing and blocking of the fan-shaped through hole on the bottom surface of the cylinder body 101.

[0039] Specifically, the motor outer frame 301 is fixedly welded to the bottom surface of the cylinder body 101 near the center, providing installation and protection space for the auxiliary motor 302 and preventing the auxiliary motor 302 from being affected by external interference or damage.

[0040] The auxiliary motor 302 is fixedly mounted inside the motor frame 301, providing power for the rotation of the sector baffle 303. It can drive the sector baffle 303 to rotate around the output end axis, thereby realizing the opening and closing of the sector through hole.

[0041] The fan-shaped baffle 303 is fixedly mounted on the output end of the auxiliary motor 302 and matches the fan-shaped through hole on the bottom surface of the cylinder body 101. When rotated to the blocking position, the top surface is tightly attached to the bottom surface of the cylinder body 101 to block the fan-shaped through hole and retain the material. When rotated to the open position, the material can be discharged from the fan-shaped through hole.

[0042] The silicone sealing strip 304 is fixed to the edge of the fan-shaped baffle 303 by a high-temperature resistant adhesive. When the fan-shaped baffle 303 is in the blocking position, it can fill the gap between the fan-shaped baffle 303 and the bottom surface of the cylinder body 101, enhance the sealing performance, and prevent hot air or materials from leaking from the gap.

[0043] See appendix Figure 1-3 As shown, the probe of the temperature sensor 4 passes through the side wall of the cylinder body 101 and is inserted into the cylinder body 101, with the tip of the probe flush with the inner wall of the cylinder body 101 to ensure accurate monitoring of the temperature around the material inside the cylinder; the temperature sensor 4 is electrically connected to the control box 8 and can transmit the monitored temperature data to the control box 8 in real time.

[0044] Specifically, the temperature sensor 4 probe passes through the side wall of the cylinder body 101 and is inserted into the interior with its end flush with the inner wall of the cylinder body 101. It can accurately monitor the temperature around the material inside the cylinder and prevent the temperature from exceeding 60-80℃, which would cause aluminum sulfate to decompose. At the same time, it is electrically connected to the control box 8 and transmits the monitored temperature data to the control box 8 in real time, providing data basis for the control box 8 to adjust the hot air assembly 5.

[0045] See appendix Figure 1-6As shown, the hot air assembly 5 includes an inlet fan 501 that is neatly and evenly distributed along the outer side of the cylinder body 101, a spiral tube heating cylinder 502 fixedly mounted on the top surface of the inlet fan 501, and a filter screen frame 503 fixedly mounted on the top surface of the spiral tube heating cylinder 502. An air inlet hole is provided on the outer side of the cylinder body 101 corresponding to the position of the inlet fan 501. The air outlet of the inlet fan 501 is connected to the air inlet hole, which can deliver outside air into the cylinder body 101. A spiral electric heating tube is fixedly mounted on the inner wall of the spiral tube heating cylinder 502. The spiral electric heating tube is electrically connected to the control box 8 and can heat the incoming air under the control of the control box 8.

[0046] Specifically, the intake fan 501 is neatly and evenly distributed along the outer side of the cylinder body 101, and its air outlet is connected to the air inlet hole on the outer side of the cylinder body 101, which can transport outside air into the cylinder body 101 to provide an air source for hot air.

[0047] The spiral heating cylinder 502 is fixedly mounted on the top surface of the inlet fan 501. The spiral electric heating tube fixedly mounted on the inner wall is electrically connected to the control box 8. Under the control of the control box 8, the outside air drawn in by the inlet fan 501 is heated to generate hot air and sent into the cylinder body 101.

[0048] The filter frame 503 is fixedly mounted on the top surface of the spiral tube heating cylinder 502 to filter the outside air entering the spiral tube heating cylinder 502, remove impurities and dust from the air, prevent impurities from entering the cylinder body 101 and contaminating the aluminum sulfate material, and ensure product purity.

[0049] See appendix Figure 1-6 As shown, the exhaust pipe 6 includes an exhaust fan 601 fixedly welded to the exhaust port of the cylinder body 101, and a telescopic pipe 602 fixedly mounted on the top surface of the exhaust fan 601; the exhaust fan 601 is electrically connected to the control box 8 and can adjust the exhaust rate under the control of the control box 8; the telescopic pipe 602 is made of high temperature resistant telescopic material, and its lower end is integrally formed with a bend matching the air outlet of the exhaust fan 601, and the upper end of the telescopic pipe 602 is integrally formed with a flange for connecting to the external exhaust pipe, and the flange is provided with evenly distributed bolt holes for easy sealing connection with the external pipe.

[0050] Specifically, the exhaust fan 601 is fixedly welded to the exhaust port of the cylinder body 101 and electrically connected to the control box 8. Under the control of the control box 8, the exhaust rate is adjusted to quickly extract the hot steam generated by drying the wet aluminum sulfate crystals inside the cylinder body 101 and accelerate the discharge of moisture.

[0051] The telescopic tube 602 is made of high-temperature resistant telescopic material. The lower end of the integrally formed bend matches the air outlet of the exhaust fan 601 for easy connection. The upper end of the integrally formed flange has evenly distributed bolt holes for easy sealing connection with the external exhaust pipe. This allows the extracted hot steam to be transported to the designated location for treatment through the external pipe, avoiding direct discharge of hot steam that could cause environmental impact or safety hazards. At the same time, the telescopic characteristics can adapt to the connection distance with the external pipe in different installation scenarios.

[0052] The operating procedure of this utility model is as follows: During material preparation, confirm that all components of the device are in their initial state, that is, the fan-shaped baffle 303 of the baffle assembly 3 is in a closed and sealed state, and the power supply of the control box 8 is not turned on. The operator slowly pours the wet aluminum sulfate crystals to be dried into the drying cylinder 1 through the feed hopper 103 on the top surface. The wet aluminum sulfate crystals slide down the feed hopper 103 into the cylinder body 101. The feed amount is controlled according to the capacity of the cylinder body 101 to avoid excessive material affecting the turning effect. When starting the control box and core components, turn on the main power switch of control box 8, and control box 8 enters the initialization state. Set the drying temperature range to 60-80℃, and simultaneously set the speed of the main motor 201 of the tumbling assembly 2, the air intake rate of the hot air assembly 5, and the exhaust rate of the exhaust fan 601 of the exhaust pipe 6. After setting the parameters, start the hot air assembly 5, the tumbling assembly 2, and the exhaust pipe 6 respectively through control box 8: After the hot air assembly 5 is started, the intake fan 501 begins to operate, drawing in outside air. The air first passes through the filter frame 503 to filter out impurities and dust before entering the spiral tube heating cylinder 502. The control box 8 controls the spiral electric heating tube inside the spiral tube heating cylinder 502 to heat the air to the set temperature range. The heated hot air enters the interior of the cylinder body 101 through the air inlet hole on the side wall of the cylinder body 101, providing heat for drying the wet aluminum sulfate crystals. When the main motor 201 of the turning component 2 is started, it drives the rotating shaft 203 to rotate around the axis of the bearing 202. The rotating shaft 203 drives multiple T-shaped shovels 204 evenly distributed on the outside to rotate synchronously. During the rotation, the T-shaped shovels 204 are in close contact with the inner wall of the cylinder body 101, constantly turning the material to prevent the wet aluminum sulfate crystals from sticking together and to ensure that the material is heated evenly. When the exhaust fan 601 of the exhaust pipe 6 is started, it operates at the set exhaust rate, drawing in the hot steam (moisture) generated during the drying process inside the cylinder body 101 through the exhaust port on the top surface of the cylinder body 101, and then transporting it to the telescopic pipe 602. Finally, through the external exhaust pipe connected to the flange at the upper end of the telescopic pipe 602, the moisture is transported to the designated location for processing. During the drying process monitoring, the temperature sensor 4 monitors the temperature around the material inside the drum body 101 in real time during device operation. Because its probe is flush with the inner wall of the drum body 101, it can accurately acquire temperature data and transmit the data to the control box 8 in real time. The control box 8 automatically adjusts the hot air assembly 5 based on the received temperature data. If the monitored temperature is below 60℃, the heating power of the spiral heating tube is increased to raise the hot air temperature; if the monitored temperature is above 80℃, the heating power of the spiral heating tube is reduced to prevent thermal decomposition of aluminum sulfate and maintain the temperature inside the drum within the set range. During the material discharge operation, after the wet aluminum sulfate crystals are dried to the required standard within the cylinder body 101 to obtain dried aluminum sulfate water purification agent, the operator first shuts off the hot air assembly 5, exhaust pipe 6, and the main motor 201 of the tilting assembly 2 on the control box 8. Then, the auxiliary motor 302 of the baffle assembly 3 is activated via the control box 8. The auxiliary motor 302 drives the fan-shaped baffle 303 to rotate around its output axis, causing the fan-shaped baffle 303 to rotate from the position blocking the fan-shaped through-hole on the bottom surface of the cylinder body 101 to the open position. At this time, the dried aluminum sulfate water purification agent, under its own weight and the guiding effect of the inclined setting of the cylinder body 101, slides from the fan-shaped through-hole on the bottom surface of the cylinder body 101 into the curved discharge trough 102, and is smoothly discharged along the curved discharge trough 102, completing one preparation operation of the aluminum sulfate water purification agent.

[0053] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
