Description

TECHNICAL FIELD

[0001] The present application relates to the field of vacuum desorption, in particular to a spiral desorption equipment. BACKGROUND

[0002] For materials with poor thermal conductivity such as solid amine, a large amount of heat needs to be absorbed during the drying and desorption process, and the heat needs to be transferred to the internal material in time, and sufficient heat exchange area is needed. When using a spiral desorption equipment for desorption, the length of the spiral cavity and the spiral body needed will be longer, and therefore a suspension bearing needs to be used for fixation. The suspension bearing will be the most easily worn part due to installation position and other reasons, so that the service life of the suspension bearing represents the service life of the desorption equipment. If the suspension bearing is damaged, the desorption equipment is basically unusable, the maintenance cost is high, and the maintenance efficiency is low. CONTENT OF THE UTILITY MODEL

[0003] The present application provides a spiral desorption equipment to solve at least one of the above technical problems in view of the above deficiencies in the prior art.

[0004] A spiral desorption equipment, comprising a shell, a transportation unit and a spiral body;

[0005] The shell is provided with a feed inlet and a discharge outlet. A plurality of parallel transportation units are arranged in the shell, and at least one spiral body is arranged in each transportation unit. The transportation units are in communication with each other, and the feed inlet and the discharge outlet are in communication through the transportation units. By using a plurality of parallel transportation units, the problem of excessive length of the spiral desorption equipment can be avoided, and the equipment is modularized. Compared with the traditional scheme, the desorption equipment does not need to be fixed by relying on a suspension bearing, and the maintenance and fault repair of the equipment are facilitated, which can effectively reduce the use cost of the equipment.

[0006] In some embodiments, the transportation unit comprises a heating transportation unit and / or a cooling transportation unit. In practical applications, some materials, such as solid amine materials, need to be cooled after the desorption process. Traditional desorption equipment needs to replace the heating medium or cool the materials separately, which consumes a long time and is complicated to operate, and limits the desorption of solid amine materials. In one embodiment, three parallel transportation units are included, which are the first transportation unit, the second transportation unit, and the third transportation unit from the feeding port to the discharging port. The first transportation unit and the second transportation unit are heating transportation units, and the third transportation unit is a cooling transportation unit. By setting two heating transportation units and one cooling transportation unit, the materials entering the transportation unit from the feeding port can be sufficiently heated, and finally cooled in the cooling transportation unit, so that the heating and cooling processes can be completed simultaneously in the same desorption equipment, the overall desorption process is integrated, the materials do not need to be discharged separately for cooling, and the desorption efficiency is higher.

[0007] In some embodiments, a material partition plate is arranged between adjacent transportation units.

[0008] The material partition plate is provided with an opening for the material to pass through.

[0009] In some embodiments, the transportation unit has a head end close to the starting end of the material transportation direction and a tail end away from the starting end of the material transportation direction.

[0010] The opening is arranged on the transportation unit corresponding to the region of the tail end; and / or

[0011] The opening is arranged on the transportation unit corresponding to the region of the head end of the adjacent transportation unit.

[0012] In some embodiments, at least two helixes are arranged in parallel in the same transportation unit.

[0013] In some embodiments, the rotation directions of the two helixes in the same transportation unit are opposite.

[0014] and / or

[0015] The two helixes in the same transportation unit are arranged up and down or left and right.

[0016] In practical applications, the rotation direction of the screw body can be determined by the arrangement direction of the helical blades on the screw body, and the screw body includes a left-handed screw body and a right-handed screw body. By arranging the screw bodies with opposite rotation directions in the same conveying unit, the heat exchange time and area of the material in the conveying unit can be increased, thereby reducing the total length of the conveying unit and the screw body, reducing the overall floor area of the desorption equipment, not relying on the suspension bearing to support the desorption equipment, and improving the processing efficiency of the material desorption. By arranging the screw bodies up and down, the floor area of the desorption equipment in the horizontal direction can be saved; by arranging the screw bodies left and right, the stability of the desorption equipment placed on the ground can be improved. In practical applications, the user can adjust the position arrangement, quantity and rotation direction of the screw bodies according to the actual needs.

[0017] In one embodiment, the same conveying unit includes two screw bodies arranged up and down and having opposite rotation directions, which are an upper screw body and a lower screw body. In one specific desorption process, the material falls into the first conveying unit from the feed port, and due to the action of gravity, the material falls into the lower screw body of the first conveying unit. The lower screw body carries the material to the upper screw body during rotation, and the upper screw body carries the material to the upper part of the conveying unit in the opposite direction for heat exchange. The opposite rotation directions of the upper screw body and the lower screw body can provide the material with a larger heat exchange area and better heat exchange effect. The material is transported from the head end of the first conveying unit to the tail end of the first conveying unit under the push of the lower screw body of the first conveying unit, and falls into the second conveying unit from the opening on the material partition plate between the first conveying unit and the second conveying unit.

[0018] In one embodiment, the rotation direction of the lower screw body of the second conveying unit is opposite to that of the lower screw body of the first conveying unit, and the rotation direction of the lower screw body of the third conveying unit is the same as that of the lower screw body of the first conveying unit, so that the transportation directions of the material between adjacent conveying units are opposite, i.e., the transportation directions of the material in the first conveying unit and the third conveying unit are consistent, and the transportation direction of the material in the second conveying unit is opposite to that in the first conveying unit and the third conveying unit. In the process of transporting the material from the first conveying unit to the third conveying unit, the overall arrangement direction presents an S shape. After the material is heated in the first conveying unit and the second conveying unit and cooled in the third conveying unit, the material is discharged from the discharge port.

[0019] In some embodiments, the helical blades of the two adjacent screw bodies in the same conveying unit are arranged alternately. In some embodiments, the screw body includes a hollow screw body.

[0020] In some specific embodiments, the conveying unit further comprises a driving device connected to the screw body to drive the screw body to rotate. In one specific embodiment, the conveying unit comprises a conveying unit shell to separate the area where the material passes through from the area where the driving device and the shaft seat are located. In actual application, the driving device comprises a motor and a speed reducer connected to each other, wherein the speed reducer is connected to the screw body through the conveying unit shell to control the rotating speed of the screw body, and the power of the motor is smoothly transmitted to the screw body to ensure the smooth operation of the equipment.

[0021] In some specific embodiments, the conveying unit further comprises a shaft seat connected to two ends of the screw body to provide support for the screw body. In actual application, the shaft seat is connected to the two ends of the screw body through the conveying unit shell to provide support for the screw body and the conveying unit shell.

[0022] In some specific embodiments, a vacuum device is further provided, which is connected to the conveying unit in the shell to form a vacuum environment in the conveying unit. By providing the vacuum device connected to the conveying unit, a vacuum environment can be formed in the conveying unit, and vacuum desorption of the material can be achieved.

As shown in Figure 1 By adopting the plurality of parallel transport units 2, the problem of too long length of the spiral desorption equipment and the spiral body 3 can be avoided, compared with the traditional scheme, the desorption equipment does not need to be fixed by relying on the suspension bearing, and the maintenance and fault repair of the equipment are facilitated, and the use cost of the equipment can be effectively reduced.

[0043] In some specific embodiments, the transport unit 2 includes a heating transport unit 2 and / or a cooling transport unit 2. In actual application, part of the material still includes a cooling process after the desorption is completed. The traditional desorption equipment needs to replace the heating medium or put the material out for separate cooling, which consumes a long time and has a complex operation, and causes certain limitation to the desorption work of the solid amine material. In one specific embodiment, as shown in Figure 2 three parallel transport units 2 are included, which are the first transport unit 21, the second transport unit 22 and the third transport unit 23 from the feeding port 11 to the discharging port 12, the first transport unit 21 and the second transport unit 22 are heating transport units 2, and the third transport unit 23 is a cooling transport unit 2. By arranging two heating transport units 2 and one cooling transport unit 2, the material entering the transport unit 2 from the feeding port 11 can be sufficiently heated, and finally enters the cooling transport unit 2 for cooling, so that the heating and cooling processes can be completed in the same desorption equipment, the overall desorption process is integrated, the material does not need to be put out separately for cooling, and the desorption efficiency is higher.

[0044] In some specific embodiments, a material partition plate 4 is arranged between adjacent transport units 2. The material partition plate 4 is provided with an opening 41 for the material to pass through.

[0045] In some specific embodiments, the transport unit 2 is close to the beginning of the material transport direction, and the end close to the beginning of the material transport direction is the head end 34, and the end away from the beginning of the material transport direction is the tail end 35.

[0046] The opening 41 is arranged on the transport unit 2 corresponding to the region of the tail end 35; and / or

[0047] The opening 41 is arranged on the transport unit 2 corresponding to the region of the head end 34 of the adjacent transport unit 2.

[0048] In actual application, the head end 34 and the tail end 34 of the screw body 3 in different transportation units 2 can be different due to the difference in the rotation direction of the screw body 3 in different transportation units 2, and the difference in the material transportation direction in different transportation units 2. In some embodiments, at least two screw bodies 3 parallel to each other are arranged in the same transportation unit 2.

[0049] In some embodiments, the rotation direction of the two screw bodies 3 in the same transportation unit 2 is opposite; and / or

[0050] The two screw bodies 3 in the same transportation unit 2 are arranged in up-down or left-right.

[0051] In actual application, as shown in Figure 5 The rotation direction of the screw body 3 can be determined by the arrangement of the helical blade 33 on the screw body 3, and the screw body 3 includes a left-handed screw body 3 and a right-handed screw body 3, which makes the rotation direction of the left-handed screw body 3 opposite to that of the right-handed screw body 3 under the driving of the same driving device 5. By arranging the screw bodies 3 with opposite rotation directions in the same transportation unit 2, the heat exchange time and area of the material in the transportation unit 2 can be increased, thereby reducing the total length of the transportation unit 2 and the screw body 3, reducing the overall floor area of the desorption equipment, not needing to rely on the suspension bearing to support the desorption equipment, and improving the processing efficiency of the material desorption. By arranging the screw bodies 3 in up-down, the floor area of the desorption equipment in the horizontal direction can be saved; by arranging the screw bodies 3 in left-right, the stability of the desorption equipment placed on the ground can be improved, and in actual application, the user can adjust the position arrangement, quantity and rotation direction of the screw body 3 according to the actual needs.

[0052] In one embodiment, as shown in Figure 4The side perspective structure of the device is shown in brief schematic view. The same transport unit 2 includes two spiral bodies 3 arranged oppositely in up-down direction, which are upper spiral body 31 and lower spiral body 32 respectively. In a specific desorption process, the material falls into the first transport unit 21 from the feeding port 11, and due to the gravity, the material falls into the lower spiral body 32 of the first transport unit 21. The lower spiral body 32 carries the material to the upper spiral body 31 in the rotating process, and the upper spiral body 31 carries the material to the upper part of the transport unit 2 in reverse direction for heat exchange. The rotating directions of the upper spiral body 31 and the lower spiral body 32 are opposite, which can make the material stay in the transport unit 2 for a longer time, have a larger heat exchange area, and make the heat exchange effect of the material better. The material is transported from the head end 34 of the first transport unit 21 to the tail end 35 of the first transport unit 21 under the pushing of the lower spiral body 32 of the first transport unit 21, and falls into the second transport unit 22 from the opening 41 on the material partition plate 4 between the first transport unit 21 and the second transport unit 22. The transport direction of the material in the spiral body can be as shown in Figure 1 and Figure 3 .

[0053] In a specific embodiment, the rotating direction of the lower spiral body 32 of the second transport unit 22 is opposite to that of the lower spiral body 32 of the first transport unit 21, and the rotating direction of the lower spiral body 32 of the third transport unit 23 is the same as that of the lower spiral body 32 of the first transport unit 21, so that the transport directions of the materials between the adjacent transport units 2 are opposite, to realize the process that the material is transported from the first transport unit 21 to the third transport unit 23, and the overall trend presents S shape, as shown in Figure 1 , Figure 3 and Figure 4 . Finally, the material is discharged from the discharge port 12 after being heated by the first transport unit 21 and the second transport unit 22 and being cooled by the third transport unit 23.

[0054] It should be noted that the arrangement direction between the transport units 2 in the shell 1 is not limited in the present application, and as long as the process of transporting and desorbing the material realized in the embodiment can be realized, the user can arrange the transport units in horizontal direction and / or vertical direction according to the actual use demand.

[0056] In some embodiments, the conveying unit 2 further comprises a driving device 5 connected to the screw body 3 to drive the screw body 3 to rotate. In one embodiment, the conveying unit 2 comprises a conveying unit 2 shell to separate the area where the material passes through from the area where the driving device 5 and the shaft seat 6 are located. In actual application, the driving device 5 comprises a motor and a speed reducer connected to each other, wherein the speed reducer is connected to the screw body 3 through the conveying unit 2 shell to control the rotating speed of the screw body 3, stably transmit the power of the motor to the screw body 3, and ensure the stable operation of the equipment.

[0057] In some embodiments, the conveying unit 2 further comprises a shaft seat 6 connected to two ends of the screw body 3 to provide support for the screw body 3. In actual application, the shaft seat 6 is connected to the two ends of the screw body 3 through the conveying unit 2 shell to provide support for the screw body 3 and the conveying unit 2 shell.

[0058] In some embodiments, a vacuum device 7 is further provided, which is connected to the conveying unit 2 in the shell 1 to form a vacuum environment in the conveying unit 2. By providing the vacuum device 7 connected to the conveying unit 2, a vacuum environment can be formed in the conveying unit 2, and vacuum desorption of the material can be achieved, which can be applied to the desorption of solid amine material. In actual application, the thermal conductivity of the solid amine material is close to that of ordinary thermal insulation materials, and the solid amine material has poor thermal conductivity compared with conventional materials, which requires a larger heat exchange area. By using the desorption equipment in this embodiment, the heat exchange area of the solid amine material during the desorption process can be effectively increased, and the heating and cooling processes can be integrated, thereby efficiently completing the desorption of the solid amine material.
