Description

Technical Field

[0001] This utility model relates to the technical field of polyferric sulfate flocculant production equipment, specifically a dryer for producing polyferric sulfate flocculant. Background Technology

[0002] Polyferric sulfate is a high-performance inorganic polymeric coagulant. It is a pale yellow, amorphous powder that is highly soluble in water; a 10% aqueous solution is a reddish-brown, transparent solution. It is hygroscopic. Polyferric sulfate is widely used in the purification of drinking water, industrial water, various industrial wastewaters, municipal sewage, and sludge dewatering. The production process of polyferric sulfate requires a drying device to dry it.

[0003] Existing drying equipment typically atomizes the liquid material through a nozzle and sprays it into the drying kettle. Then, hot air is sent into the drying kettle to heat the liquid material. However, the hot air cannot raise the temperature inside the drying kettle quickly, which results in the drying process taking a lot of time and reducing the efficiency of the drying equipment. At the same time, material accumulation at the outlet of the drying kettle can easily cause blockages, requiring workers to clear the blockages and increasing their workload.

[0004] According to CN217828894U, a dryer for producing polyferric sulfate flocculant includes a spray dryer. The spray dryer contains a heating mechanism and a cleaning mechanism. The heating mechanism includes a fixed pipe, a jet pipe, and a jet head. The top of the fixed pipe is fixedly connected to the top of the spray dryer. The jet pipe is annular and fixedly connected to the bottom of the fixed pipe, communicating with it. The cleaning mechanism includes a rotating ring and a scraper. The top of the scraper is fixedly connected to the bottom of the rotating ring. The outer side of the scraper is attached to the inner wall of the spray dryer. A rotating block is fixedly connected to the outer side of the scraper. A rotating groove is formed on the inner wall of the spray dryer, and the rotating block is slidably connected inside the rotating groove. This invention can solve the problems of material accumulation and adhesion on the inner wall of the spray dryer and uneven liquid heating in the prior art.

[0005] According to the dryer described above, the hot air cannot quickly raise the temperature inside the drying kettle, which means that the drying of the liquid material takes a lot of time and reduces the efficiency of the drying equipment. At the same time, the material accumulation at the outlet of the drying kettle can easily cause blockage, requiring workers to clear the blockage and increasing the workload of the workers. Therefore, we need to propose a dryer for producing polyferric sulfate flocculant. Utility Model Content

[0024] Please see Figure 1-4 This utility model provides a technical solution: a dryer for producing polyferric sulfate flocculant, including a drying kettle 1, a mounting frame 2 fixedly connected to the bottom end of the drying kettle 1, a feed pipe 3 provided at the top end of the drying kettle 1, the bottom end of the feed pipe 3 penetrating the wall of the drying kettle 1 and connected to an atomizing nozzle 4, the atomizing nozzle 4 located in the inner cavity of the drying kettle 1, a discharge pipe 5 opened on the lower surface of the drying kettle 1, an anti-clogging structure 6 installed in the inner cavity of the discharge pipe 5 to prevent clogging, an air supply component 7 for increasing drying efficiency installed on the outer wall of the drying kettle 1, and a heating pipe 8 and a temperature sensor 9 installed in the inner cavity of the drying kettle 1, the heating pipe 8 being spirally arranged; start-up. Heating tube 8 heats the inside of drying kettle 1. Then, the air supply component 7 is activated to send outside air into the inner cavity of drying kettle 1, accelerating the heating effect of heating tube 8. After the internal temperature of drying kettle 1 is reached, the liquid material is fed in through the feed pipe 3 and sprayed into the inner cavity of drying kettle 1 through the atomizing nozzle 4 for drying. The dried material is discharged through the discharge pipe 5. The anti-clogging structure 6 is activated to clear the discharge pipe 5, preventing the material from clogging the discharge pipe 5, thereby shortening the time required for the liquid material drying process, increasing the working efficiency of the drying equipment, preventing the discharge port of drying kettle 1 from being blocked, avoiding the need for personnel to clear the blockage, and reducing the workload of the personnel.

[0025] The anti-clogging structure 6 includes a stepper motor 61, which is fixedly connected to the outer wall of the discharge pipe 5 via a mounting plate. The output shaft of the stepper motor 61 is fixedly connected to a rotating rod 62. The other end of the rotating rod 62 passes through the discharge pipe 5 and is rotatably connected to the inner wall of the discharge pipe 5 via a rotating shaft. A guide plate 63 is fixedly connected to the surface of the rotating rod 62. The guide plate 63 is located in the inner cavity of the discharge pipe 5. When the stepper motor 61 is started, it provides driving force to drive the rotating rod 62 to rotate. The rotating rod 62 drives the guide plate 63 to rotate inside the discharge pipe 5, so that the guide plate 63 pushes the material to move.

[0026] The guide plate 63 is arc-shaped and there are four sets of guide plates 63. The four sets of guide plates 63 are arranged in an impeller shape. The four sets of guide plates 63 are arranged in an impeller shape to clear and guide the material in the discharge pipe 5 and prevent the material from accumulating and blocking the discharge pipe 5.

[0027] The air supply assembly 7 includes a blower 71, which is fixedly connected to the outer wall of the drying kettle 1 via a mounting plate. The air outlet of the blower 71 is connected to an air supply pipe 72, and the other end of the air supply pipe 72 extends through and into the inner cavity of the drying kettle 1. The air inlet of the blower 71 is connected to an air inlet pipe 73, and the other end of the air inlet pipe 73 is attached to a dust cover 74. When the blower 71 is started, it provides driving force, causing the air inlet pipe 73 to draw in external air. After the dust in the air is filtered by the dust cover 74, the air is sent into the air supply pipe 72. The air supply pipe 72 sends the air into the interior of the drying kettle 1. The air drives the heat inside the drying kettle 1 to flow rapidly, increasing the heating efficiency of the heating tube 8.

[0028] The top of the drying kettle 1 is also provided with an air outlet 10. The inner cavity of the air outlet 10 is equipped with a filter screen. The air outlet 10 allows the air inside the drying kettle 1 to be discharged through the air outlet 10.

[0029] A temperature display 11 is installed on the outer wall of the drying kettle 1. The temperature display 11 is electrically connected to the temperature sensor 9. The temperature display 11 allows the staff to easily observe the heating temperature inside the drying kettle 1.

[0030] The surface of the drying vessel 1 is provided with a slot, and an observation window 12 is embedded in the inner cavity of the slot. The observation window 12 is transparent, allowing the staff to easily observe the drying process of the liquid material.

[0031] In practical use: The heating element 8 is activated to heat the interior of the drying vessel 1. Then, the blower 71 is activated to provide driving force, causing the air inlet pipe 73 to draw in external air. After the dust is filtered by the dust cover 74, the air is sent into the air supply pipe 72. The air supply pipe 72 then delivers the air into the interior of the drying vessel 1. The air causes the heat inside the drying vessel 1 to flow rapidly, increasing the heating efficiency of the heating element 8. Once the temperature inside the drying vessel 1 is reached, the liquid material is fed into the atomizing nozzle 4 through the feed pipe 3. The atomizing nozzle 4 atomizes and sprays the liquid material into the interior of the drying vessel 1. The material is dried and discharged through the discharge pipe 5. The stepper motor 61 is started to provide driving force to drive the rotating rod 62 to rotate. The rotating rod 62 drives the guide plate 63 to rotate inside the discharge pipe 5. The four sets of guide plates 63 are arranged in an impeller shape to clear and guide the material in the discharge pipe 5, avoiding the accumulation and blockage of material in the discharge pipe 5. This shortens the time required for the material to dry, increases the working efficiency of the drying equipment, avoids blockage of the discharge port of the drying kettle 1, avoids the need for personnel to clear the blockage, and reduces the workload of the personnel.
