The fixed sleeve 4 is provided with a material tank 71. A slide 11 is provided in the ingredient tank 71, and a slide bar 72 is slidably connected to the slide 11 provided in the ingredient tank 71. A drawer 73 is fixedly connected to one side of the slide bar 72. A discharge pipe 75 is connected to one side of the drawer 73. An electronic valve 76 is provided on the outside of the discharge pipe 75. A connecting pipe 8 is connected to one side of the discharge pipe 75. The detachable storage assembly 7 and the detachable connecting pipe 8 provided on the top of the reactor 1 facilitate the discharge of the ingredients in the drawer 73 and the addition of ingredients to the drawer 73. By setting a weighing assembly that can sense and display the overall weight of the storage assembly 7, the purpose of quantitative discharging is achieved. The vibration assembly is provided to facilitate the increase of the discharge speed.

[0023] The pressure sensor 5 is electrically connected to the display screen 6. One side of the ingredient tank 71 is hollowed out. Several discharge pipes 75 are passed through the hollow part of the ingredient tank 71, which is convenient for the user to read the weight value and convenient for moving and taking out the drawer 73. A bent plate 74 with an inclined and arc-shaped setting is fixedly connected to the inside of the drawer 73. A handle 10 is fixedly connected to one side of the drawer 73 and the top of the ingredient tank 71, which is convenient for concentrating the ingredients in the drawer 73 at a position close to the discharge pipe 75 and for controlling the removal of the drawer 73 and the ingredient tank 71. and placement; one end of the connecting pipe 8 is inserted into the feed port 2, and a fixing block 9 is fixedly connected to the outside of the connecting pipe 8. The bottom of the fixing block 9 fits tightly with the cover plate of the feed port 2, which is convenient for the unloading of the discharge pipe 75 and the fixation of the connecting pipe 8; one side of the fixed sleeve 4 is fixedly connected to a support frame 15 composed of a horizontal plate and a vertical plate, and a vibration motor 12 is provided on the top of the support frame 15. A vibration ball 13 is fixedly connected to one side of the output shaft of the vibration motor 12, and a rubber layer 14 is fixedly connected to the inside of the fixed sleeve 4, which is convenient for increasing the unloading speed of the discharge pipe 75.

[0024] Working process: When the equipment is in operation, the external power supply is turned on. When the reactor 1 used in the production of hydroxypropyl methylcellulose is used, the reactor 1 is first placed in a suitable position, the cover of the feed port 2 is opened, and the raw material of hydroxypropyl methylcellulose is added into the reactor 1. The user holds the handle 10 at the bottom drawer 73 and moves it forward. The slides 72 on both sides of the drawer 73 move in the chute 11 opened in the ingredient tank 71 until it is completely taken out. Then all the drawers 73 are taken out in the same way from bottom to top, and the raw materials are put into the drawers 73 in the same way. The ingredients to be added are placed first, and then the handle 10 on the top of the ingredient tank 71 is held to place the ingredient tank 71 in the fixed sleeve 4 and fit tightly with the rubber layer 14. Then one end of the connecting pipe 8 is inserted into the feed port 2, and the fixing block 9 on the outside of the connecting pipe 8 fits tightly with the cover of the feed port 2 to simply fix the position of the connecting pipe 8. Then the drawers 73 filled with different ingredients are put back into the ingredient tank 71 in order from top to bottom. During the process of the drawer 73 moving to the ingredient tank 71, one end of the discharge pipe 75 is gradually inserted into the connecting pipe 8. The material pipe 75, the connecting pipe 8, the feed port 2 and the reactor 1 are interconnected. When a specific ingredient needs to be added, the user activates the electronic valve 76 on the outside of the corresponding discharge pipe 75. Since the drawer 73 is provided with an inclined, arc-shaped bent plate 74 and the discharge pipe 75 is inclined, the ingredients in the drawer 73 fall from the discharge pipe 75 to the connecting pipe 8 and then fall into the reactor 1. After opening the electronic valve 76, the user observes the weight sensed by the pressure sensor 5 displayed on the display screen 6 and quantifies the ingredients according to the reduced value. When discharging the material and observing the display screen 6 and finding that the value has not changed or the change speed is too slow, start the vibration motor 12, and the vibration ball 13 drives the ingredient tank 71 to be in a vibrating state, thereby accelerating the falling speed of the ingredients in the drawer 73. The detachable storage component 7 and the detachable connecting pipe 8 arranged on the top of the reactor 1 facilitate the discharging of the ingredients in the drawer 73, and at the same time facilitate the addition of materials to the drawer 73. By setting a weighing component that can sense and display the overall weight of the storage component 7, the purpose of quantitative discharging is achieved. The vibration component is set to facilitate increasing the discharging speed.
