Description

Technical Field

[0001] This utility model relates to the technical field of drying devices, specifically to a uniform drying device for the production of polyferric sulfate. Background Technology

[0002] Polyferric sulfate is a high-molecular-weight coagulant commonly used in the purification of drinking water, various industrial waters, and municipal wastewater. It is a pale yellow amorphous powder that is highly soluble in water.

[0003] Because it is highly soluble in water, it needs to be dried during the preparation process to keep it dry. However, current dryers often result in significant differences in drying effect between the inside and outside of the material due to material accumulation. Therefore, this paper proposes a uniform drying device for the production of polyferric sulfate. Utility Model Content

[0004] The technical problem this invention aims to solve is that current dryers often result in significant differences in drying effects between the inside and outside of the material due to material accumulation. This invention provides a uniform drying device for the production of polyferric sulfate, which can perform processes such as turning the material to avoid accumulation and ensure that all materials are heated evenly, thereby guaranteeing the synchronous drying effect of the same batch of materials.

[0005] The technical solution adopted by this utility model to solve the technical problem is: a uniform drying device for the production of polyferric sulfate, including a processing tank, an inner cavity is opened inside the processing tank, a main pipe is fixedly connected to the middle of the bottom side wall of the inner cavity, a spiral rod is rotatably installed in the middle of the main pipe, a flow divider is fixedly connected to the outer ring wall of the top of the main pipe, a dispersion plate is fixedly connected to the inner wall of the inner cavity and the outer ring wall of the main pipe, and the dispersion plates are staggered with each other, and an electric heating ring is embedded in the inner wall of the processing tank and the outer ring wall of the main pipe.

[0006] As a preferred technical solution of this utility model, the dispersion plate is a ring structure with the top sidewalls tilted downwards. Each dispersion plate has two inner grooves, and each inner groove can be detachably connected to a vibration motor.

[0007] As a preferred technical solution of this utility model, the bottom end of the spiral rod is rotatably connected to the middle of the bottom side wall of the inner cavity, and both sides of the bottom end of the main pipe are provided with material inlets, and the top end of the main pipe has an open structure.

[0008] As a preferred embodiment of this utility model, the diverter plate has an annular structure and the top is inclined downwards. The top sidewall of one end of the diverter plate is on the same plane as the top opening edge of the main pipe.

[0009] As a preferred technical solution of this utility model, a motor is detachably connected to the middle of the top side wall of the processing tank. The output end of the motor extends into the inner cavity and is fixedly connected to a connecting door plate. Material-pushing plates are fixedly connected to the bottom side walls at both ends of the connecting door plate. One side of the material-pushing plate is inclined, and the bottom side wall of the material-pushing plate is in contact with the top side wall of the diversion plate.

[0010] As a preferred embodiment of this utility model, a feed pipe is fixedly connected to the top side wall of the treatment tank, and the feed pipe communicates with the inner cavity. A steam exhaust pipe is fixedly connected to the top side wall of the treatment tank away from the feed pipe. A filter plate is fixedly connected to the through hole of the treatment tank corresponding to the steam exhaust pipe. The bottom side wall of the inner cavity has a conical structure and two discharge ports are opened through it. A sealing plate is inserted into the discharge port.

[0011] This invention has the following advantages: When the material is fed into the inner cavity, it will slide down from the top of the dispersing plate in sequence. During the sliding process, the material will be dispersed and will not gather. In this way, the dispersed material can be uniformly irradiated and heated by the electric heating ring, avoiding accumulation and affecting the drying effect of the inner and outer layers of the material. When the material accumulates at the bottom of the inner cavity, it will slide towards the middle along the bottom slope, and then enter the main pipe through the feed port on the side wall of the main pipe. The rotating screw will transport the material upward, and then it will fall back down through the diversion plate and slide down the dispersing plate again. This can effectively improve the drying efficiency and ensure the uniformity of drying of the same batch of material. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to the following: Figure 1-3This utility model discloses a uniform drying device for the production of polyferric sulfate, comprising a processing tank 1, an inner cavity 6 inside the processing tank 1, a main pipe 8 fixedly connected to the middle of the bottom side wall of the inner cavity 6, a spiral rod 9 rotatably installed in the middle of the main pipe 8, a flow divider plate 10 fixedly connected to the outer ring wall of the top of the main pipe 8, a dispersion plate 11 fixedly connected to both the inner wall of the inner cavity 6 and the outer ring wall of the main pipe 8, and the dispersion plates 11 are staggered with each other, and an electric heating ring 12 is embedded in the inner wall of the processing tank 1 and the outer ring wall of the main pipe 8.

[0018] The dispersing plate 11 has a ring structure and its top sidewall is inclined downwards. Each dispersing plate 11 has two inner grooves 16. Each inner groove 16 is detachably connected to a vibration motor 17. The bottom end of the spiral rod 9 is rotatably connected to the middle of the bottom sidewall of the inner cavity 6. The two sidewalls of the bottom end of the main pipe 8 are through-holes with material inlets. The top of the main pipe 8 has an open structure. The diverting plate 10 has a ring structure and its top is inclined downwards. The top sidewall of one end of the diverting plate 10 is on the same plane as the top opening edge of the main pipe 8. The top sidewall of the processing tank 1 is detachably connected to a motor 2. The output end of the motor 2 extends into the inner cavity 6 and is fixedly connected to a connecting door plate 7. The bottom sidewalls of both ends of the connecting door plate 7 are fixedly connected to a material-pushing plate 15. One side of the material-pushing plate 15 is inclined. The bottom sidewall of the material-pushing plate 15 is in contact with the top sidewall of the diverting plate 10.

[0019] The technical effects of this solution are as follows: The starting motor 2 drives the screw rod 9 and the connecting door plate 7 to rotate. As the screw rod 9 rotates, it can transport the material at the bottom upwards, realizing the flipping of the material from top to bottom and inside to outside. The material discharged from the top of the main pipe 8 will fall onto the diversion plate 10 and slide down along the diversion plate 10. Because the rotation of the connecting door plate 7 will drive the material-pushing plate 15 to move on the diversion plate 10, the inclined surface of the material-pushing plate 15 will push the material on the diversion plate 10 outwards, so that the material will fall and then fall one by one onto the dispersion plate 11, realizing the effect of multiple scattering of the material. This can prevent the material from agglomerating, ensure the uniformity and fullness of the material heating, avoid the accumulation that causes differences in drying effect, and improve the drying efficiency. The vibration motor 17 can ensure that the material on the dispersion plate 11 slides smoothly and avoids accumulation.

[0020] A feed pipe 3 is fixedly connected to the top side wall of the treatment tank 1. The feed pipe 3 communicates with the inner cavity 6. A steam exhaust pipe 4 is fixedly connected to the top side wall of the treatment tank 1 away from the feed pipe 3. A filter plate 5 is fixedly connected to the through hole corresponding to the steam exhaust pipe 4. The bottom side wall of the inner cavity 6 has a conical structure and two discharge ports 13 are opened through it. A sealing plate 14 is inserted into the discharge port 13.

[0021] The technical effect of this solution is as follows: the material can be fed into the inner cavity 6 through the feed pipe 3. Water vapor will be generated during drying. The water vapor will be discharged through the exhaust pipe 4. In order to prevent the material from being discharged from the exhaust pipe 4, a filter plate 5 is set to filter the material. A cover can be placed on the feed pipe 3. After drying, the cover plate 14 can be pulled out, so that the material can be discharged through the discharge port 13 for the next batch of drying.

[0022] Specifically, when using this utility model, the material to be processed is fed into the inner cavity 6 through the feed pipe 3. This material will be initially diverted and sprinkled along the dispersing plate 11. The material is initially dried by the pre-activated electric heating ring 12. As the material accumulates at the bottom of the inner cavity 6, a portion of it will enter through the material inlet at the bottom of the main pipe 8. The starting motor 2 drives the connecting door plate 7 and the screw rod 9 to rotate synchronously, thereby conveying the material at the bottom upwards and finally discharging it from the opening at the top of the main pipe 8. The rotating material-pushing plate 15 can push the material out and then disperse it through the dispersing plate 11. Repeating this action can perform comprehensive drying of the material, improve drying efficiency, and avoid uneven drying. Then, the sealing plate 14 is pulled out to discharge the material.

[0023] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0024] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
