Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] refer to Figure 1 , Figure 1 This is a schematic diagram of the automatic preparation system for special materials provided by the present invention.

[0023] The present invention provides a special material automatic preparation system for preparing toxic, irritating and volatile materials, which mainly includes a material unit, a batching unit, a conveying pipe group, a weighing device 18, a conveying pump, a solenoid valve group and a control device.

[0024] The material unit is used to temporarily store materials and absorb and treat toxic, irritating and volatile harmful gases. The delivery pump is connected to the batching unit and the external use unit. The processed materials are compressed by air to form positive pressure in the closed material unit, and the materials are pressed into the batching barrel 10 for weighing, stirring and liquid preparation. During this process, the weighing device 18 weighs the batching barrel 10, and the control device controls the opening and closing and opening degree of the solenoid valve on the delivery pipe group to control the liquid preparation process. The prepared materials are output to the outside through the delivery pump.

[0025] Specifically, the material unit includes a material temporary storage chamber 1, an exhaust hood 4, a material barrel 2, an exhaust gas cleaning chamber 3, a fan 5, a first explosion plate 6 and a material bracket 7. The exhaust hood 4 is covered on the top of the material temporary storage chamber 1, and the material barrel 2 is placed inside the material temporary storage chamber 1.

[0026] The batching unit comprises a batching barrel 10 , a batching support 11 for placing the batching barrel 10 , and a second explosion plate 12 .

[0027] The above-mentioned conveying pipe group includes an exhaust gas intake pipe 8, a compressed air intake pipe 9, a material feed pipe 13, an exhaust gas discharge pipe 14 and a feeding pipe 15. The exhaust gas intake pipe 8, the compressed air intake pipe 9, the material feed pipe 13, the exhaust gas discharge pipe 14 and the feeding pipe 15 are all provided with solenoid valves, and the solenoid valves are communication-connected to the control equipment.

[0028] Among them, the exhaust gas intake pipe 8 is connected to the material temporary storage chamber 1 and the exhaust gas cleaning chamber 3, the compressed air intake pipe 9 is inserted into the exhaust hood 4 and the material temporary storage chamber 1, the outer end of the compressed air intake pipe 9 is connected to the air-conditioning system, the batching feed pipe 13 is connected to the material barrel 2 and the batching barrel 10, the exhaust gas discharge pipe 14 is inserted into the batching barrel 10 and connected to the exhaust gas intake pipe 8, and the feeding pipe 15 is used to connect the batching barrel 10 with the conveying pump.

[0029] The material barrel 2 is passed into the material temporary storage cabin 1 through the material conveying door. After the material conveying door is closed, the power of the fan 5 is turned on, the material barrel 2 is opened, and the compressed air intake pipe 9 of the batching unit and the batching feed pipe 13 are simultaneously inserted into the material barrel 2 port for docking. The material temporary storage cabin 1 takes in air through the air inlet 22. The exhaust hood 4 at the upper end of the material temporary storage cabin 1 discharges the harmful gas in the cabin through the fan 5. The exhaust hood 4 is connected to the exhaust cleaning chamber 3 through the exhaust air intake pipe 8. The end of the exhaust air intake pipe 8 is connected to the first explosion disk 6. The gas bulges out from the first explosion disk 6. The gas is transformed into small bubbles through the first explosion disk 6 to increase the surface area of ​​the bubbles and increase the processing efficiency. The exhaust cleaning chamber 3 uses different cleaning agents for different materials. The reagents enter the exhaust cleaning chamber 3 through the feed port of the exhaust cleaning chamber 3, and the waste liquid after neutralization and detoxification is discharged from the cleaning agent discharge port. The materials in the cabin are compressed by the air conditioning system to form a positive pressure in the closed material barrel 2, and the materials are pressed into the batching barrel 10 for liquid preparation.

[0030] The air is connected to the second explosion plate 12 through the compressed air inlet pipe 9, and the air bulges out from the second explosion plate 12 to form tumbling gas to complete the stirring. After the stirring is completed, the liquid material is sent to the use unit through the suction pipe 15 and the conveying pump.

[0031] This application can be applied to most special liquid substances with high volatility, can automatically control the emission of waste gas and waste liquid, has the functions of special material preparation and waste gas absorption, and can control the dosage of the medicine by itself, so as to realize automatic feeding of special liquids without manual control, with high efficiency and precision.

[0032] In order to ensure the sealing effect, the material unit, the conveying pipe group, the batching unit and the conveying pump are tightly connected.

[0033] The above-mentioned delivery pump can be specifically a vacuum pump, which can not only pump materials, but also use air pressure transmission. The above-mentioned control device can be a PLC or a controller.

[0034] Furthermore, a cleaning spray water inlet pipe 16 can be provided at the top of the batching barrel 10, which is connected to an external water source, and a solenoid valve is installed on the pipe, and the solenoid valve is connected to the control device through communication. A cleaning discharge port 20 is provided at the bottom of the batching barrel 10. After the material is transported, online cleaning is performed through the cleaning spray water inlet pipe 16, and the cleaning liquid is discharged through the cleaning discharge port 20. Thus, cleaning after automatic configuration is achieved. An external discharge pipe 21 is provided in the batching barrel 10, and the gas is further discharged through the external discharge pipe 21. The external discharge pipe 21 can be externally connected to an exhaust gas treatment device to achieve exhaust gas recovery.

[0035] In order to realize automatic stirring of materials, a magnetic stirring device can be arranged in the batching barrel 10. The magnetic stirring device can be connected to the control device for communication and automatically start the stirring action according to the weighing conditions to ensure that the acid is mixed evenly and reduce the operation of personnel.

[0036] An exhaust pipe 17 is arranged above the exhaust cleaning chamber 3. The upper exhaust pipe 17 can be connected to the exhaust system of the air conditioning system to prevent the exhaust air from being discharged into the environment and causing pollution, thereby saving energy and protecting the environment.

[0037] In order to achieve the purification and recovery of waste gas, a recovery device can be set in the exhaust pipe 17 and the exhaust port interlayer. The recovery device can absorb the volatile gas of highly toxic materials and prevent the highly toxic material gas from entering the air-conditioning system or the surrounding environment to pollute the equipment and the environment; when the pH value of the recovery device shows neutral, the neutralizing liquid can be replaced to ensure the purification effect.

[0038] The exhaust hood is preferably made of corrosion-resistant transparent acrylic plate or glass to achieve a closed state, facilitate observation, and further improve environmental protection performance.

[0039] The batching barrel 10 can be a weighing device or a digital liquid level gauge on the market. The weighing device is preferably a weighing device made of corrosion-resistant material to achieve automatic weighing during the batching process.

[0040] On the basis of the above scheme, in order to facilitate weighing of ingredients, a door-insertion lifting fixture 19 can be provided at the bottom of the weighing device 18, and the door-insertion lifting fixture 19 realizes the separation of weight measurement and measured material.

[0041] Specifically, firstly, the weighing device 18 is placed in the peripheral frame of the batching support 11, and the height of the door-inserted lifting fixture 19 is adjusted so that the weighing device 18 only contacts the four supporting rods of the door-inserted lifting fixture 19. When calibration is required, the four supporting rods are sequentially put into the slots and fixed with pins. At this time, the weight of the configuration barrel is all applied to the peripheral frame, and the weighing device 18 is not subjected to force. At this time, calibration can be performed. After the calibration is completed, the pin of the door-inserted lifting fixture 19 is pulled out, and the four supporting rods are supported on the weighing device 18, so as to facilitate the measurement of the weight of the liquid medicine. The design of the peripheral frame and the door-inserted lifting fixture 19 facilitates the frequent calibration and use of the weighing device 18.

[0042] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0043] The above is a detailed introduction to the automatic preparation system for special materials provided by the present invention. Specific examples are used in this article to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea.
