Description

Technical Field

[0001] The utility model belongs to the technical field of polyaluminium chloride production, in particular to a drum drying device for polyaluminium chloride production. Background Art

[0002] Polyaluminium chloride has the properties of adsorption, condensation and precipitation. It has poor stability and is corrosive. It has the advantages of good spray drying stability, wide adaptability to water areas, fast hydrolysis rate, strong adsorption capacity, large alum flowers, fast dense precipitation, low turbidity of water outlet, and good dehydration performance. In the process of production and processing, polyaluminium chloride needs to be dried to obtain products. It can be done through a drum drying device to ensure the production quality of the product. The drum dryer is a contact internal heating conduction type drying machine. During the drying process, the heat is transferred from the inner wall of the drum to its outer wall, passing through the dried material attached to the outer wall of the drum, and evaporating the water on the material. It is a continuous drying production machine. However, some existing devices will cause material residues due to insufficient fluidity of the material inside the drum during drying. Some existing drying devices are a relatively sealed space, and the internal components of the equipment may be difficult to inspect and maintain regularly. This may lead to an increase in the failure rate of the equipment, thereby affecting production efficiency and product quality. During the production process, the material may remain inside the drum, and the inside of the device is not easy to open, so these residues may not be effectively removed, resulting in quality problems in the next production.

[0003] The existing authorization number is CN212842619U, which discloses a drum drying device for the production of polyaluminium chloride, including: a support seat, a collection barrel and a barrel cover, wherein the collection barrel is arranged between the support seats, the barrel cover is arranged on the upper side of the collection barrel, and an air outlet pipe is arranged at the center of the upper end of the barrel cover. The beneficial effect is that the utility model can collect and discharge the steam during drying through the barrel cover, the discharge pipe and the ventilation fan, so as to avoid the steam from floating around and ensure the drying effect of the product, and the high-temperature steam can be evenly discharged from the inside of the drying barrel through the steam outlet pipe, so that the steam can be evenly diffused to various positions inside the drying barrel, so as to ensure the drying effect of the drying barrel.

[0004] However, when the above device is used, although multiple air outlet pipes are provided, the ends thereof are easily blocked by the accumulated materials, which reduces the drying efficiency and causes the materials to remain inside the drum. These residues may not be effectively removed; at the same time, after the materials are dried, the materials inside the drum may not be easily discharged from the discharge end, which increases the difficulty and time of discharging. Therefore, it is necessary to propose a drum drying device for the production of polyaluminium chloride to solve the above problems. Utility Model Content

The entire structure can be tilted to a desired angle, which can help the dried material to be discharged more smoothly from the inside of the drying cylinder, avoiding the accumulation of material in the drying cylinder, which affects the drying effect and production efficiency.

[0009] As a further solution of the present invention, the stirring blades are fixed on the inner wall of the drying drum in a group of three at intervals of 120° around the center of the circle, and three groups of stirring blades are fixed at equal distances inside the drying drum.

[0010] As a further solution of the utility model, a driving device is fixed on the left side of the mounting cylinder, a rotating groove matching the gear of the driving device is provided on the drying cylinder, and the drying cylinder is rotated inside the mounting cylinder by the driving device, so that the material can be more fully mixed during the drying process.

[0026] Please refer to Figure 1 -7. A drum drying device for the production of polyaluminium chloride, comprising: a mounting cylinder 2 hinged on the top of a bottom plate 1, and a drying cylinder 5 rotatably connected to the inside of the mounting cylinder 2 for drying polyaluminium chloride, a tilting mechanism 3 is provided on the top of the bottom plate 1, the mounting cylinder 2 is hinged on the side of the top of the bottom plate 1 away from the tilting mechanism 3, and the bottom of the mounting cylinder 2 is connected to the tilting mechanism 3, a feeding mechanism 4 is hinged on the side of the mounting cylinder 2 away from the tilting mechanism 3, a drying cylinder 5 for rotary drying materials is rotatably connected inside the mounting cylinder 2, and a stirring blade 6 is fixed inside the drying cylinder 5, and a driving device 8 is installed on the side of the mounting cylinder 2 close to the tilting mechanism 3.

[0027] Preferably, the tilt mechanism 3 includes a drive motor 31, an adjustment rod 32, a ball screw sleeve 33 and a ball screw 34. A groove matching the ball screw 34 is opened on the left side of the base plate 1. The ball screw 34 is rotatably connected to the base plate 1. The ball screw sleeve 33 is threadedly sleeved on the ball screw 34. One side of the adjustment rod 32 is hinged on the ball screw sleeve 33. The other end of the adjustment rod 32 is fixed to the bottom of the mounting tube 2, and the upper end of the ball screw sleeve 33 is hingedly connected to the mounting tube 2 through the adjustment rod 32. When the drive motor 31 is started and drives the ball screw 34 to rotate, the thread on the ball screw 34 contacts the ball screw sleeve 33, pushing the ball screw sleeve 33 along As the screw rod moves, since the adjusting rod 32 is connected to the mounting cylinder 2, when the ball screw sleeve 33 moves along the screw rod, the adjusting rod 32 will pull the mounting cylinder 2 to move accordingly. As the mounting cylinder 2 moves, it will cause the entire structure to tilt to a desired angle. In order to control the tilt angle and speed, this can be achieved by adjusting the speed of the drive motor 31 or using other control systems. When the structure needs to be restored to its original position, it only needs to drive the motor 31 to rotate in the opposite direction to drive the mounting cylinder 2 back to its original position. This can help the dried material to be discharged more smoothly from the inside of the drying cylinder 5, thereby avoiding accumulation of material in the drying cylinder 5, which affects the drying effect and production efficiency.

[0028] Preferably, three stirring blades 6 are fixed on the inner wall of the drying cylinder 5 at intervals of 120° around the center of the circle, and three groups of stirring blades 6 are fixed at equal distances inside the drying cylinder 5. The stirring blades 6 play a stirring role when the drying cylinder 5 rotates, so that the material is more fully mixed during the drying process, which helps to improve the efficiency of heat exchange and ensure that the material is evenly heated and dried. These stirring blades 6 also help to push the material to move toward the discharge end. The inclined design of the stirring blades 6 can use gravity and the rotational power of the drying cylinder 5 to push the material to move toward the discharge end when the drying cylinder 5 is tilted.

[0029] Preferably, a driving device 8 is fixed to the left side of the mounting cylinder 2, a rotating groove that cooperates with the gear of the driving device 8 is provided on the drying cylinder 5, and the drying cylinder 5 rotates inside the mounting cylinder 2 through the driving device 8, and the feeding mechanism 4 includes a feed hopper 41, a cylinder cover 42, a fan 43 and a discharge hopper 44, the cylinder cover 42 is a cylindrical structure, the feed hopper 41 and the discharge hopper 44 are both funnel-shaped structures, the feed hopper 41 and the discharge hopper 44 are fixed oppositely at the top and bottom of the cylinder cover 42, and are both connected with the inside of the cylinder cover 42. Before starting work, the cylinder cover 42 can be opened to clean or maintain the inside of the drying cylinder 5. After confirming that there is no problem, the cylinder cover 42 can be closed, and the material can be placed from the position of the feed hopper 41, and the equipment can be started to rotate the drying cylinder 5, and after drying, the dried material can be discharged from the position of the discharge hopper 44.

[0030] Preferably, the fan 43 is installed at the center position of one side of the cylinder cover 42 away from the mounting cylinder 2, and a ventilating hole cooperating with the fan 43 is opened on the cylinder cover 42. When drying, the fan 43 can discharge water vapor and other gases inside the drying cylinder 5 to avoid affecting the drying effect.

[0031] The working principle of a drum drying device for polyaluminium chloride production provided by the utility model is as follows:

[0032] Before starting to use, it is necessary to open the drum cover 42 to check whether the inside of the drying drum 5 is clean. After the inspection is completed, the drum cover 42 is closed.

[0033] The material to be dried is put into the feed hopper 41 so that the material flows into the drying drum 5, and the equipment is started to rotate the drying drum 5, and the driving device 8 is started to rotate the drying drum 5 in the installation drum 2.

[0034] The stirring blades 6 stir the material in the drying drum 5 so that the material is more fully mixed during the drying process. During the drying process, the working state of the equipment and the changes of the material are closely monitored, and the changes in the color, humidity and other relevant indicators of the material inside the drying drum 5 are observed to ensure that the drying process proceeds as expected. If necessary, appropriate adjustments can be made to optimize the drying effect.

[0035] When the material reaches the required degree of dryness, the mounting cylinder 2 can be tilted to the required angle through the tilting mechanism 3, and the stirring blades 6 inside the drying cylinder 5 can use gravity and the rotational power of the drying cylinder 5 to prompt the material to move to the discharge hopper 44, thereby discharging the material. After completing the tilting operation, the mounting cylinder 2 is restored to the horizontal position. Only after ensuring that the cylinder is completely restored to the horizontal position can the normal drying operation be continued.

[0036] The above steps can be repeated for multiple drying operations according to production needs. Pay attention to selecting appropriate drying parameters and time according to the characteristics and requirements of the material to ensure the quality and consistency of the final product.

[0037] After use, turn off the equipment and wait for it to cool down, clean the remaining materials or impurities inside the drying drum 5, and regularly perform maintenance and service on the drum drying device, including cleaning the inside of the drying drum 5, checking and replacing worn parts, and lubricating moving parts, etc., to extend its service life and ensure that it can work normally next time.

[0038] Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations or direct or indirect applications may be made to these embodiments without departing from the principles and spirit of the present invention. In other related technical fields, the scope of the present invention is defined by the attached claims and their equivalents, which are equally included in the scope of patent protection of the present invention.
