Description

Technical Field

[0001] The utility model belongs to the technical field of stirring equipment, and in particular relates to a material mixing equipment capable of adding steam. Background Art

[0002] Steam agitators currently play an important role in industrial production, especially in processes that require heating and mixing materials. However, existing designs have some limitations. The steam inlet is usually located at the top of the box. Although this layout is convenient for installation and maintenance, the natural rising characteristics of the gas lead to uneven distribution of steam in the material. Especially at the bottom of the box, it is difficult for steam to fully penetrate, which not only affects the heating efficiency of the material, but may also lead to uneven heating, which in turn affects the quality of the final product.

[0003] The related technology introduces steam into the bottom of the side of the material mixing device. During the stirring process, the steam moves from bottom to top, so that the steam is distributed more evenly in the material. When the steam is introduced, a cylinder and a piston are used for auxiliary cooperation. When steam is passed, the cylinder drives the piston to open the steam inlet. When steam is not passed, the cylinder drives the piston to close the steam inlet. At this time, when the steam inlet is closed, steam may flow back at the piston or condense and then flow back, affecting the operation of the cylinder.

[0004] In order to solve the above technical problems, the utility model designs a material mixing device capable of adding steam. Utility Model Content

[0023] Embodiment 1

[0024] Combination Figure 1-3As shown, the embodiment of the present disclosure provides a material mixing device capable of adding steam, comprising a shell 1, a steam cylinder 2, a steam branch pipe 3, a three-way valve 4 and a valve port switch assembly 5, wherein the shell 1 is provided with a steam inlet 11, the steam inlet 11 is provided at the bottom of the side of the shell 1 and is connected to the first end of the three-way valve 4; one end of the steam branch pipe 3 is connected to the steam cylinder 2, and the other end is connected to the second end of the three-way valve 4; the valve port switch assembly 5 comprises a cylinder 51 and a piston rod 52, the cylinder 51 is connected to the third end of the three-way valve 4 The piston rod 52 is arranged in the three-way valve 4 and there is a gap between it and the wall of the three-way valve 4; a sealing member 41 is provided in the three-way valve 4, and the sealing member 41 is arranged between the intersection of the three-way valve 4 and the third end, and the outer side is circumferentially embedded in the wall of the three-way valve 4, and the inner side is circumferentially against the wall of the piston rod 52; wherein the inner diameter of the sealing member 41 is the same as the diameter of the wall of the piston rod 52, and when the piston rod 52 moves to the retracted position and the extended position, the sealing member 41 is respectively against the first end 53 and the second end 54 of the piston rod 52.

[0025] The material mixing device capable of adding steam provided by the embodiment of the present disclosure is adopted. Steam is introduced from the bottom of the side of the shell 1 of the material mixing device, so that the steam diffuses from bottom to top, fully contacts the material during the mixing process, and the internal steam distribution is more uniform, and the material mixing is more uniform. A valve port switch assembly 5 is set to control the opening and closing of the steam branch pipe 3 and the steam inlet 11. When the steam is passed, the cylinder 51 drives the piston rod 52 to move in a direction away from the steam inlet 11. The connecting pipe steam branch pipe 3 and the steam inlet 11, the diameter of the piston rod 52 is slightly smaller than the inner diameter of the three-way valve 4, and there is a gap between the piston rod 52 and the wall of the three-way valve 4, so that the design of the baffle can be avoided, making the structure simpler. The setting of the gap can avoid the deformation of the piston rod 52 during the working process, and give the piston rod 52 a certain deformation space. A seal 41 is set between the wall of the piston rod 52 and the wall of the three-way valve 4, which can prevent the steam from flowing back to one side of the cylinder 51, and can also prevent the steam from liquefying and flowing back into the cylinder 51 between the seal 41 and the first end, so as to avoid affecting the normal operation of the cylinder 51.

[0026] Furthermore, the seal 41 is annular or quasi-annular, with its outer side embedded in the wall of the three-way valve 4 and fixedly connected to the inner wall of the three-way valve 4, and its inner side abutting against the wall of the piston rod 52. The piston rod 52 can move between a retracted position and an extended position along the three-way valve 4 to approach or move away from the steam inlet 11 relative to the seal 41 under the drive of the cylinder 51. Figure 2 As shown, Figure 2The state of the piston rod 52 in the retracted position and the extended position is shown. When the piston rod 52 moves to the retracted position, the seal 41 abuts against the first end 53 of the piston rod 52. When the piston rod 52 moves to the extended position, the seal 41 abuts against the second end 54 of the piston rod 52. That is to say, the piston rod 52 at least partially abuts against the seal 41 during the movement to avoid the phenomenon of separation from the seal 41, so that the seal 41 can always play a sealing role between the three-way valve 4 and the piston rod 52.

[0027] Preferably, the three-way valve 4 is provided with a drain port, and the drain port is provided between the sealing member 41 and the first end.

When the steam is liquefied, the drain port can be opened to discharge the liquefied water out of the three-way valve 4 to avoid affecting the subsequent introduction of steam.
