[0029] Reference Figure 1 The embodiment of the present application provides a material blocking device, which is arranged in a cylinder 1 and includes:

[0030] A stirring member 2 is rotatably disposed in the cylinder 1, and the stirring member 2 includes a rotating component 21 and a plurality of blades 22 uniformly distributed on the rotating component 21; and

[0031] The purge mechanism 3 is disposed in the cylinder 1 , and includes a purge member 31 . The purge member 31 is located above the paddle 22 , and the purge member 31 is spaced apart from and aligned with the paddle 22 .

[0032] The cylinder 1 is provided with materials with high water content that need to be dried. When the materials are being dried, the rotating component 21 is rotated to drive the materials in the cylinder 1 to turn over. After the materials are stirred, the contact area between the materials and the gas in the cylinder 1 is increased to ensure the drying effect. However, during the turning process of the materials with high water content, the materials are easily turned into blocks with the paddles 22, which affects the evaporation of water inside the block materials, and further affects the overall drying effect of the materials. By arranging a purge member 31 in the cylinder 1, the purge member 31 is located above the paddle 22 and is spaced from the paddle 22, so that when the materials are lifted and turned over, the purge member 31 can prevent the materials from turning with the paddle 22 under the blocking effect of the purge member 31, reduce the phenomenon of material agglomeration, ensure the evaporation of water inside the materials, and further ensure the drying effect of the materials.

[0033] The purge mechanism 3 also includes a driving member, and the movable end of the driving member is connected to the purge member 31; the purge member 31 is connected to the movable end of the driving member, and when the movable end of the driving member moves, the purge member 31 will be driven to move synchronously to meet the needs of users in different scenarios. Among them, the movable end of the driving member can move along a straight line, or move along a curve, or the movable end of the driving member can be rotated. Correspondingly, the movement of the movable end of the driving member will drive the purge member 31 to move along a straight line, or move along a curve, or be rotated. It can be known that under different movement modes, the driving member can use a driving component that can realize the movement trajectory, such as a cylinder, an electric push rod, a motor or an electric motor.

[0034] Optionally, the driving member includes a lifting driving member, and the lifting end of the lifting driving member is connected to the purge member 31. The lifting driving member can be a cylinder, a hydraulic cylinder, an electric push rod, or a motor and a screw rod. For example, the lifting driving member is a lifting cylinder, and the lifting end of the lifting cylinder is the piston rod of the lifting cylinder, and the piston rod of the lifting cylinder is connected to the purge member 31; therefore, the extension and retraction of the piston rod of the lifting cylinder will drive the synchronous lifting and lowering of the purge member 31. Since the purge member 31 is located above the paddle 22, the purge member 31 will adjust the distance between the purge member 31 and the paddle 22 when it is lifted and lowered, so that the material can be evenly dispersed according to different types of materials.

[0035] The purge member 31 is provided with a plurality of purge holes 33, and a blowing channel 32 is formed inside the purge member 31. The air outlet end of the blowing channel 32 is connected to the purge hole 33, and the air inlet end of the blowing channel 32 is connected to an air source. The air source is used to provide gas, and the gas can enter through the blowing channel 32 and be blown out through the purge hole 33. The gas blown out from the purge hole 33 acts on the paddle 22 or acts on the inside of the material. The gas acting on the paddle 22 can blow off the residual material on the paddle 22, thereby reducing the residual rate of the material inside the cylinder 1; and the gas acting on the inside of the material can further achieve a blowing effect on the block material, thereby improving the drying effect.

[0036] Wherein, the gas source includes an inert gas, and the inert gas includes nitrogen or dry air, etc. When the gas source is an inert gas, the gas source passes the inert gas into the interior of the material, and the inert gas can also bring out the moisture inside the material, which can accelerate the flow of water vapor inside the material, accelerate the evaporation of water, and improve the drying efficiency. Of course, the purge hole 33 can also be directly connected to the interior of the cylinder 1, and the inert gas directly passing into the interior of the cylinder 1 can also accelerate the flow of water vapor in the cylinder 1 and improve the drying efficiency.

[0037] In some embodiments, the stirring member 2 has a first state and a second state, and the stirring member 2 is in the first state, and the air source is intermittently passed into the blowing channel 32; wherein, the first state of the stirring member 2 is the working state of the stirring member 2, that is, the material is located in the cylinder 1, and the stirring member 2 is rotatably arranged in the cylinder 1, so as to stir and disperse the material located in the cylinder 1. In this process, the air source is intermittently passed into the blowing channel 32, which can accelerate the flow of water vapor inside the material or inside the cylinder 1, and at the same time, the stability of the material drying process can be guaranteed. Compared with the traditional drying of high-water-content materials, since the amount of water vapor in the cylinder 1 is particularly large, and the top of the cylinder 1 is an arc-shaped structure, although there is a vacuum pump at the rear end to evacuate, the water vapor in the cylinder 1 cannot be discharged smoothly from the inside of the cylinder 1, thereby affecting the drying efficiency of the cylinder 1. The technical solution provided by the present application, in the process of material drying, introduces inert gas into the inside of the cylinder 1, which can accelerate the evaporation of water and greatly improve the drying efficiency.

[0038] When the stirring member 2 is in the second state, the gas source is continuously introduced into the blowing channel 32, and the purge hole 33 is arranged toward the paddle 22; the second state of the stirring member 2 is the shutdown state of the stirring member 2, that is, the material in the cylinder 1 has been dried, and the dried material will be discharged normally. After the discharge is completed, since the paddle 22 and the bottom of the cylinder 1 are arranged at an angle, the material on the inclined surface of the paddle 22 will be subjected to extrusion force during the drying process, and at the same time, after these materials are dried, some materials will remain on the paddle 22. If the material and the paddle 22 are turned into blocks, the block material is dry outside and wet inside, which will aggravate the residue of the material on the paddle 22, thereby affecting the residual rate of the material in the cylinder 1. After the stirring member 2 is dried, the present application continuously introduces gas into the purge hole 33, and the purge hole 33 continuously blows toward the paddle 22, so that the material on the inclined surface of the paddle 22 can be purged down, which can greatly reduce the residual rate of the material inside the cylinder 1.

[0039] Optionally, the gas source includes a high-pressure inert gas, and by blowing air toward the blades 22 through the high-pressure gas source, the possibility of blowing the material off the blades 22 can be further guaranteed. Of course, in order to further improve the purging effect on the material on the blades 22, the gas outlet of the purge hole 33 can also be increased, and the inclined surface of the blades 22 can be purged with a large volume or a high-pressure large volume of dry nitrogen. This can greatly reduce the material residue rate of the cylinder 1, reduce the difficulty of manual cleaning, and will not affect the quality of the material between batches. At the same time, since the stirring member 2 is rotatably arranged, only one purge member 31 is required, and each blade 22 is aligned with the purge member 31 by the rotation of the rotating part 21 to achieve the purge of the blades 22, so that one purge member 31 can clean multiple blades 22 on the rotating part 21, thereby reducing the overall cost of the device.
