Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] See Figures 1-5 In this embodiment of the present invention, a mixer for xylene production and processing includes a mixing tank 1. A fixing frame 3 is fixedly connected to the top of the mixing tank 1, and a feeding tank 4 is fixedly connected to the fixing frame 3. A filling tank 5 is fixedly connected to the bottom of the feeding tank 4. Multiple sets of circumferentially equidistant discharge holes 9 are provided on the inner wall of the filling tank 5. A first one-way valve 10 is installed in each discharge hole 9. A stop block 6 is fixedly connected to the top of the filling tank 5. A piston plate 7 is slidably connected inside the filling tank 5, and a second one-way valve 25 is installed inside the piston plate 7. A motor 13 is fixedly connected to the bottom of the mixing tank 1, and a device is fixedly connected to the output shaft of the motor 13. A rotating block 14 is located inside the mixing tank 1. Multiple sets of circumferentially distributed blades 15 are fixedly connected to the rotating block 14. A fixed seat 19 is fixedly connected to the outer wall of the filling tank 5. A rotating frame 18 is rotatably connected to the fixed seat 19 via bearings. A connecting frame 17 is fixedly connected to the rotating machine. A vertical plate 16 is fixedly connected to the rotating frame 18 and the blade 15 assembly. The blades 15 are set at an angle. The vertical plate 16 is inclined to the inner wall of the mixing tank 1. A stop tooth 24 is fixedly connected to the inner wall of the vertical plate 16. A spiral groove 20 is fixedly connected to the inner wall of the mixing tank 1 between the inner wall of the mixing tank 1 and the vertical plate 16.

[0020] The top of the feeding tank 4 is fixedly connected to the mounting frame 11, and the telescopic mechanism 12 is fixedly connected to the mounting frame 11. The output shaft of the telescopic mechanism 12 is fixedly connected to the piston plate 7.

[0021] This invention first injects benzene raw material into mixing tank 1 and adds methylation raw material into feeding tank 4. Then, when methylation of benzene raw material is required, the piston plate 7 is driven by telescopic mechanism 12 to reciprocate in feeding tank 5. When piston plate 7 rises, first one-way valve 10 closes and second one-way valve 25 opens. At this time, the raw material in feeding tank 4 passes through second one-way valve 25 into feeding tank 5, thereby completing the quantitative replenishment of raw material in feeding tank 5. Then, the piston plate 7 is controlled to descend. At this time, first one-way valve 10 opens and second one-way valve 25 closes. At this time, the raw material in feeding tank 5 is rapidly injected into mixing tank 1 along first one-way valve 10 under the pressure of piston plate 7, thereby completing the initial mixing of benzene raw material and methylation raw material. The quantitative addition of methylation raw material can be achieved by the number of times piston plate 7 rises and falls, thereby achieving accurate control of benzene raw material and methylation raw material.

[0022] Meanwhile, this utility model can also drive the rotating block 14 to rotate via the motor 13, and the rotating block 14 drives the blade 15 to rotate. At this time, through the inclined setting of the blade 15, the rotational driving force of the blade 15 is converted into the vertical driving force of the raw materials in the mixing tank 1. During this process, the raw materials at the bottom of the mixing tank 1 move to the top of the mixing tank 1 under the action of the vertical driving force generated by the blade 15. During the movement, the raw materials in the mixing tank 1 rotate. At this time, the rotating raw materials generate centrifugal force. Then, the rotating raw materials in the mixing tank 1 move from the bottom of the inner wall of the mixing tank 1 to the top of the inner wall of the mixing tank 1 along the direction of the spiral groove 20, thereby forming a continuous upward flow in the mixing tank 1, thereby realizing the continuous up-and-down circulation and mixing of the raw materials in the mixing tank 1, thereby accelerating the all-round rapid stirring of the raw materials in the mixing tank 1.

[0023] In one instance of this embodiment, please refer to Figures 1-5 The bottom of the mixing tank 1 is fixedly connected to a support leg 2. This utility model supports and fixes the equipment by setting the support leg 2.

[0024] In one instance of this embodiment, please refer to Figures 1-5 The bottom of the mixing tank 1 is provided with a discharge hole 21, and a discharge pipe 22 is fixedly connected inside the discharge hole 21. A control valve 23 is installed inside the discharge pipe 22. This utility model discharges the processed raw materials through the setting of the discharge hole 21 and the discharge pipe 22, and controls the opening and closing of the discharge hole 21 through the setting of the control valve 23.
