[0002] Silica gel particles are a highly active adsorption material primarily composed of silicon dioxide (SiO2). They are chemically stable, insoluble in water and all solvents, and unreactive with all substances except strong bases and hydrofluoric acid. They are commonly used as desiccants, moisture-proof beads, deodorizers, and various adsorbents, as well as for purifying kerosene and adsorbing aromatic hydrocarbons. They are also used as catalysts and catalyst supports in the production of key industrial products such as melamine, phthalic anhydride, maleic anhydride, butadiene rubber, and acrylonitrile.

A feeding pipe 204 located between the two fixed cavities 201 is installed in the middle of the lower end surface of the quantitative box 2. Two adjusting arc plates 203 arranged opposite to each other are provided inside the feeding pipe 204. Electric push rods 202 with output ends detachably connected to the adjusting arc plates 203 are installed on opposite sides of the two fixed cavities 201.

[0021] The lower end face of the storage box 1 is connected to a discharge pipe 101 which passes through and extends to the interior of the metering box 2. A flow controller 102 is installed on the discharge pipe 101. A push rod 105 is provided inside the storage box 1. The upper end face of the push rod 105 is fixedly connected to a movable plate 104 located above the storage box 1. The outer wall of the storage box 1 is fixedly connected to a horizontal plate. The upper end face of the horizontal plate is installed with a first cylinder 103 whose output end is fixedly connected to the movable plate 104.

[0022] In this embodiment, the solenoid valve on the outer wall of the discharge pipe 101 is opened to allow the desiccant in the storage box 1 to fall into the quantitative box 2. At the same time, the flow controller 102 (the specific structure and principle of the flow controller 102 are prior art and have been disclosed in Patent No.: CN210503264U) can measure the falling desiccant, control the amount of discharge from the discharge pipe 101, and thus quantify the desiccant entering the quantitative box 2. During the discharge process, the discharge pipe 101 can drive the movable plate 104 to move up and down through the first cylinder 103, prompting the push rod 105 to move up and down in the discharge pipe 101, thereby dredging the discharge pipe 101, improving the discharge efficiency, and avoiding the blockage of the discharge pipe 101 causing slow discharge.

[0023] Secondly, the quantitative desiccant entering the quantitative box 2 can be discharged through the discharge pipe 204, and the electric push rod 202 can be activated according to the diameter of the packaging bag of the desiccant and the size of the desiccant particles, so that the two electric push rods 202 push the two adjustment arc plates 203 to move closer to or away from each other, thereby adjusting the size of the discharge opening of the discharge pipe 204. By adjusting the size of the discharge pipe 204, accurate discharge of desiccant of different specifications can be achieved to meet the packaging requirements of silica gel particles of different sizes and shapes.

[0024] As a technical optimization solution of the present invention, the upper parts of the two adjustment arc plates 203 are both inclined structures.

[0025] In this embodiment, the upper halves of the two regulating arc plates 203 are inclined, so that the desiccant entering the quantitative box 2 can smoothly fall between the regulating arc plates 203 in the discharge pipe 204 .

[0026] As a technical optimization solution of the present invention, a fixing frame 3 is provided below the quantitative box 2, a placement plate 301 is provided above the fixing frame 3, and a second cylinder 302 whose output end is fixedly connected to the placement plate 301 is installed on the lower end surface of the fixing frame 3.

[0027] In this embodiment, a packaging bag that needs to be quantitatively packaged with desiccant is placed on the upper end surface of the placement plate 301, and the second cylinder 302 is started, so that the second cylinder 302 pushes the placement plate 301 upward until the packaging bag is sleeved on the outer wall of the adjustment arc plate 203 and the upper end surface abuts against the bottom end of the discharge pipe 204, thereby facilitating the quantitative packaging of desiccant into the packaging bag.

[0028] As a technical optimization solution of the present invention, a solenoid valve located above the flow controller 102 is installed on the outer wall of the discharge pipe 101 .

[0029] In this embodiment, a solenoid valve is provided to control the discharge pipe 101 to discharge or stop the discharge.

[0030] As a technical optimization solution of the present invention, outer walls of the storage box 1 and the quantitative box 2 are both hinged with box doors.

[0031] In this embodiment, the interior of the storage box 1 and the quantitative box 2 can be cleaned by opening the box doors.

[0032] As a technical optimization solution of the present invention, a controller is installed on the outer wall of the storage box 1, and the first cylinder 103, the flow controller 102, the solenoid valve, the electric push rod 202 and the second cylinder 302 are all electrically connected to the controller.

[0033] In this embodiment, the controller can control the first cylinder 103, the flow controller 102, the solenoid valve, the electric push rod 202 and the second cylinder 302 to work normally.

[0034] Working principle: First, place the packaging bag on the upper end surface of the placement plate 301 and align it with the adjustment arc plate 203, and start the second cylinder 302 to push the placement plate 301 upward until the packaging bag is sleeved on the outer wall of the adjustment arc plate 203 and the upper end surface abuts against the bottom end of the discharge pipe 204. Then, open the solenoid valve on the outer wall of the discharge pipe 101 to make the desiccant in the storage box 1 fall into the quantitative box 2. At the same time, the flow controller 102 (the specific structure and principle of the flow controller 102 are all prior art) is used to control the desiccant in the storage box 1. , and disclosed in Patent No.: CN210503264U) can measure the falling desiccant, control the amount of material discharged from the discharge pipe 101, and then quantify the desiccant entering the quantitative box 2. During the discharge process, the discharge pipe 101 can drive the movable plate 104 to move up and down through the first cylinder 103, prompting the push rod 105 to move up and down in the discharge pipe 101 to dredge the discharge pipe 101. When the desiccant in the quantitative box 2 reaches the set amount, the controller can control the electromagnetic valve on the outer wall of the discharge pipe 101 to close;

[0035] Secondly, the quantitative desiccant entering the quantitative box 2 can be discharged through the discharge pipe 204, and the electric push rod 202 can be activated according to the diameter of the packaging bag of the desiccant and the size of the desiccant particles, so that the two electric push rods 202 push the two adjustment arc plates 203 to move closer to or away from each other, thereby adjusting the size of the discharge opening of the discharge pipe 204. By adjusting the size of the discharge pipe 204, accurate discharge of desiccant of different specifications can be achieved to meet the packaging requirements of silica gel particles of different sizes and shapes.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
