[0031] EMBODIMENT

[0032] REFERENCE Figures 1-4 For one embodiment of the present application, a quantitative feeding device for chemical material processing is provided, comprising:

[0033] The feeding unit comprises a material box, a plurality of partitions are arranged inside the material box, the partitions divide the internal space of the material box into a plurality of material grooves, a plurality of feeding pipes corresponding to the material grooves are communicated at the bottom of the material box, the end of the feeding pipe is communicated with a switching bin, and the feeding unit further comprises a suction assembly for extracting chemical materials.

[0034] The buffer unit comprises a switching pipe fixedly arranged at the bottom of the switching bin, the end of the switching pipe is fixedly communicated with a discharging cylinder, the bottom of the discharging cylinder is provided with a discharging nozzle, the top of the discharging cylinder is provided with a first hydraulic rod, the output end of the first hydraulic rod extends into the inside of the discharging cylinder and is fixedly connected with a pull rod, the bottom of the pull rod is fixedly connected with a sealing plug, and the sealing plug is used for sealing the discharging nozzle.

[0035] The end of the feeding pipe is internally provided with a first one-way valve, and the beginning of the adapter pipe is internally provided with a second one-way valve, the first one-way valve allows the chemical material to flow from the tank to the adapter bin, and the second one-way valve allows the chemical material to flow from the adapter bin to the adapter pipe.

[0036] The pumping assembly comprises a mounting plate fixedly installed on one side of the tank, a first fixing plate is fixedly installed on the front side of the mounting plate, and a plurality of dosing cylinders are fixedly connected to the first fixing plate, and the bottom of the dosing cylinder is in communication with the adapter bin.

[0037] A second fixing plate is fixedly installed on the mounting plate, a second hydraulic rod is fixedly installed on the second fixing plate, a push-pull plate is fixedly connected to the output end of the second hydraulic rod, a plurality of piston rods are arranged on the push-pull plate, and the number of the piston rods is the same as that of the dosing cylinders, and a sealing piston is fixedly connected to one end of the piston rod inside the dosing cylinder.

[0038] Two symmetrically arranged guide rods are fixedly connected between the first fixing plate and the second fixing plate, the guide rods pass through the push-pull plate, and the guide rods are in sliding connection with the push-pull plate.

[0039] The adapter pipe, the adapter bin and the dosing cylinder are all made of stainless steel, and the sealing plug and the sealing piston are both made of silica gel.

[0040] During use, the second hydraulic rod is started, the output end of the second hydraulic rod is retracted, and the push-pull plate is driven to move upwards along the guide rods. The piston rods on the push-pull plate move upwards along with the push-pull plate, and the sealing pistons on the piston rods move upwards in the dosing cylinders, so that a negative pressure is formed in the dosing cylinders. Under the action of the negative pressure, the chemical material in the tank is drawn into the adapter bin through the feeding pipe and the first one-way valve, and then into the dosing cylinder. Since the first one-way valve only allows the chemical material to flow from the tank to the adapter bin, the chemical material cannot flow back to the tank.

[0041] The second hydraulic rod is started again, the output end of the second hydraulic rod is extended, and the push-pull plate is driven to move downwards along the guide rods. The piston rods on the push-pull plate move downwards along with the push-pull plate, and the sealing pistons on the piston rods move downwards in the dosing cylinders, so that the chemical material in the dosing cylinders is extruded. The extruded chemical material enters the adapter pipe through the adapter bin and the second one-way valve, and since the second one-way valve only allows the chemical material to flow from the adapter bin to the adapter pipe, the chemical material cannot flow back to the adapter bin. The chemical material enters the dosing cylinder through the adapter pipe, and at this time, the first hydraulic rod is in the extended state, the sealing plug seals the dosing nozzle, and the chemical material is temporarily stored in the dosing cylinder, achieving buffering.

[0042] When the chemical material needs to be put, the first hydraulic rod is started, the output end of the first hydraulic rod is retracted, and the pull rod is driven to move upward. The pull rod drives the sealing plug to move upward, opens the discharging nozzle, and the chemical material in the discharging cylinder is put into the designated position through the discharging nozzle, and the quantitative putting of the chemical material is completed. After the putting is completed, the first hydraulic rod is extended, the sealing plug is driven to move downward, the discharging nozzle is sealed again, and the next putting is waited. The device works in the above-mentioned process circulation, and realizes the continuous quantitative putting of the chemical material.

Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and they should be covered in the scope of the claims of the present application.
