[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0018] Please refer to Figures 1 to 3 , in the embodiment of the present utility model, a dryer for acetylene production includes a dryer main body 1 composed of a drying tank 101, an exhaust pipe 102, an intake pipe 103, a loading port 104, and a discharge port 105. The exhaust pipe 102 is fixed at an eccentric position on the top of the drying tank 101, the intake pipe 103 is fixed at the central position at the bottom of the drying tank 101, the loading port 104 and the discharge port 105 are respectively fixed at the upper and lower ends on one side of the drying tank 101, and a range extension component 2 is provided at the top and inside of the drying tank 101. The range extension component 2 is used to increase the contact travel of acetylene with the molecular sieve inside the drying tank 101.
[0019] The range extension component 2 includes a travel amplification unit, a loading and unloading unit, and an intake air shunt unit.
[0020] The travel amplification unit is used to limit the path of acetylene flowing from the intake pipe 103 to the exhaust pipe 102, so as to increase the contact travel of acetylene with the molecular sieve inside the drying tank 101. The loading and unloading unit is used to assist in the unloading and loading operations of the molecular sieve inside the drying tank 101. The intake air shunt unit is used to shunt the acetylene gas flow entering from the intake pipe 103 to achieve all-round contact between acetylene and the molecular sieve.
[0021] The travel amplification unit includes a rotating shaft 202 and a spiral air guide plate 203. The rotating shaft 202 is distributed at the central position inside the drying tank 101. The spiral air guide plate 203 is fixed outside the rotating shaft 202, and the edge of the spiral air guide plate 203 is attached to the inner wall of the drying tank 101. The molecular sieve is filled inside the drying tank 101 along the spiral trajectory of the spiral air guide plate 203.
[0022] The acetylene that enters the interior of the drying tank 101 through the intake pipe 103 will move upward along the filling path of the molecular sieve to the exhaust pipe 102, which is used to increase the contact travel of the acetylene with the molecular sieve; the intake air shunting unit includes an intake air groove 205, a shunting groove opening 206, an arc-shaped through groove 207, and a shunting intake hole 208.
[0023] The intake air groove 205 is opened at the bottom of the rotating shaft 202, and the shunting groove opening 206 is opened at a position near the bottom on the outer side of the rotating shaft 202 and is communicated with the intake air groove 205.
[0024] The arc-shaped through groove 207 is opened inside the arc-shaped push plate 204 and penetrates through the rotating shaft 202 to be communicated with the intake air groove 205, and the shunting intake hole 208 is opened at the top of the arc-shaped push plate 204 and is communicated with the arc-shaped through groove 207.
[0025] The acetylene that enters the interior of the intake air groove 205 through the intake pipe 103 is dispersed into the inner cavity of the drying tank 101 through the path composed of the shunting groove opening 206, the arc-shaped through groove 207, and the shunting intake hole 208, so as to achieve sufficient contact with the molecular sieve.
[0026] The bottom of the rotating shaft 202 and the arc-shaped push plate 204 are attached to the bottom inner wall of the drying tank 101, and the top of the intake pipe 103 extends into the interior of the intake air groove 205 and is located below the arc-shaped through groove 207.
[0027] In this embodiment: It should be added that: During daily use, the charging port 104 and the discharging port 105 are connected with a sealing plate through a flange, and the exhaust pipe 102 and the intake pipe 103 are connected with external pipes through a flange. The drying process of acetylene is as follows:
[0028] The acetylene containing water vapor enters the interior of the intake air groove 205 from the intake pipe 103, and then is shunted through the separation groove opening 206 and the arc-shaped through groove 207. Among them, the acetylene flowing through the separation groove opening 206 enters the middle part of the inner cavity of the drying tank 101. And the acetylene flowing through the arc-shaped through groove 207 is shunted again through a plurality of shunting intake holes 208, and the acetylene flowing through the plurality of shunting intake holes 208 enters the peripheral area of the inner cavity of the drying tank 101, so as to achieve sufficient contact between the acetylene and the molecular sieve at the bottom of the drying tank 101.
[0029] After that, the acetylene will flow towards the top of the drying tank 101. During this process, due to the blockage of the spiral air guiding plate 203, the acetylene cannot flow directly upward and can only flow along the spiral track of the spiral air guiding plate 203. Compared with the traditional structure in which the molecular sieve is directly filled inside the drying tank 101, the flow path of the acetylene is longer, that is, the contact travel of the acetylene with the molecular sieve is longer. Through this structure, the absorption effect of the molecular sieve on the water vapor in the acetylene can be effectively improved, and the drying effect of the acetylene is further improved.
[0030] Please refer particularly to Figures 1 to 3 , the loading and unloading unit includes a motor 201 and an arc-shaped push plate 204; the top of the rotating shaft 202 penetrates to the top of the drying tank 101, and the motor 201 is installed at the center position of the top of the drying tank 101 and its output end is fixedly connected to the rotating shaft 202; there are multiple arc-shaped push plates 204, and the multiple arc-shaped push plates 204 are evenly distributed in a ring and fixed to the outer side of the bottom of the rotating shaft 202; when discharging through the discharge port 105, the motor 201 is driven by the motor 201 to drive the spiral air guide plate 203 and the arc-shaped push plate 204 to rotate synchronously, and the rotation of the arc-shaped push plate 204 can push the molecular sieve close to the discharge port 105 to achieve the purpose of improving the efficiency.
[0031] When loading through the loading port 104, the molecular sieve fills the inside of the drying tank 101 in all directions by the rotation of the spiral air guide plate 203 and the arc-shaped push plate 204.
[0032] In this embodiment: After the dryer runs for a period of time, it is necessary to replace the molecular sieve inside the drying tank 101. At this time, stop the machine and cut off the communication channel with the external pipeline, and then open the discharge port 105 first. At this time, the molecular sieve inside the drying tank 101 can be discharged through the discharge port 105. During this process, the motor 201 can be started, and the motor 201 drives the rotating shaft 202, the spiral air guide plate 203, and the arc-shaped push plate 204 to rotate synchronously. The rotation of the spiral air guide plate 203 disperses the molecular sieve from each other, and its overall fluidity is better. In addition, combined with the rotation of the arc-shaped push plate 204 to push the molecular sieve towards the discharge port 105, the rapid discharge of the molecular sieve can be achieved. Compared with the traditional structure that relies on the self-weight of the molecular sieve for discharging, the discharging efficiency is faster.
[0033] After all the molecular sieve is discharged, the discharge port 105 can be closed, and then the loading port 104 is opened. The new molecular sieve is transported to the loading port 104 through an external feeding device and falls into the drying tank 101. During this process, the motor 201 can remain in the running state, so that the molecular sieve completely fills the space between the bottom of the spiral air guide plate 203 and the bottom of the drying cylinder 101, effectively ensuring the subsequent drying stability.
[0034] Please refer particularly to Figures 2 to 3 , the inner wall width of the shunt trough 206 and the aperture of the shunt air inlet hole 208 are both smaller than the diameter of the molecular sieve.
[0035] In this embodiment: Through this structure, the molecular sieve can be prevented from entering the air inlet groove 205 and the arc-shaped through groove 207 through the shunt trough 206 and the shunt air inlet hole 208.
[0036] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
