[0032] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are 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.

[0033] The present invention provides a system for pre-processing waste chemical reagents by dispensing and ejecting. The system comprises a reagent dispensing device and an ejecting device connected to the reagent dispensing device. The reagent dispensing device and the ejecting device are connected by a conveyor belt. Figure 1 As shown, the reagent dispensing device includes a control device, a reagent bottle dispensing rotating disk 610, a reagent dispensing mechanism 620, a bottle cap adding mechanism 630 and a bottle cap tightening mechanism 640, and the reagent dispensing mechanism 620, the bottle cap adding mechanism 630 and the bottle cap tightening mechanism 640 are sequentially arranged at intervals according to the rotation direction of the reagent bottle dispensing rotating disk 610; the reagent dispensing mechanism 620, the bottle cap adding mechanism 630 and the bottle cap tightening mechanism 640 are all provided with sensors for detecting whether the reagent bottle is in place; the control device is respectively connected to the reagent dispensing mechanism 620, the bottle cap adding mechanism 630, the bottle cap tightening mechanism 640 and the sensor;

[0034] Among them, the reagent dispensing mechanism 620 includes a peristaltic pump and a liquid injection head connected to the peristaltic pump, the liquid pipette of the peristaltic pump is connected to the waste chemical reagent, and the liquid injection head is located at the upper part of the mouth of the empty reagent bottle 611. The bottle cap installation mechanism 630 includes a cover body arranging mechanism and a cover body conveying channel. The outlet of the cover body conveying channel is located at the upper part of the reagent bottle mouth, and the cover body sliding off from the outlet of the cover body conveying channel can be buckled onto the reagent bottle mouth. The bottle cap tightening mechanism 640 includes a cylinder device, a rotating motor seat, a rotating motor arranged on the rotating motor seat, and a rotating head arranged on the rotating shaft of the rotating motor. The size of the rotating head matches the size of the cover body. The cylinder device drives the rotating motor seat to move up and down, and the rotating motor is connected to the control device.

[0035] The empty reagent bottle 611 transported by the conveyor belt first arrives at the reagent bottle filling rotating disk 610. As the reagent filling rotating disk rotates, the waste chemical reagent is first injected under the reagent filling mechanism 620620, and then the bottle cap is installed under the action of the bottle cap installing mechanism 630, and finally the bottle cap is tightened under the action of the bottle cap tightening mechanism 640. The tightened reagent bottle is transported to the feed port of the ejection device through the conveying device.

[0036] Specifically, Figure 2 and Figure 3 As shown, the ejection device for processing waste test bottles of the present invention comprises a driving device 300, an ejection rod 100 and an ejection channel 200. The driving device 300 drives the ejection rod 100 so that the ejection rod 100 can reciprocate in the ejection channel 200; wherein the closed end of the ejection channel 200 is connected to one end of the elastic member 110, and the other end of the elastic member 110 is connected to the ejection end of the ejection rod 100. When the ejection rod 100 moves toward the driving end of the ejection rod 100, since one end of the ejection member is fixedly connected to the ejection end of the ejection rod 100 and the other end of the elastic member 110 is fixedly connected to the closed end of the ejection channel 200, the elastic member 110 can be made to reciprocate. The elastic rod can accumulate elastic potential energy, and the elastic rod can move toward the open end of the ejection channel 200 under the action of the elastic member 110; the ejection channel 200 is provided with a feed port 210, and the feed is used to add the reagent bottle containing the waste chemical reagent into the ejection channel 200; when the driving device 300 drives the ejection rod 100 to move toward the closed end of the ejection channel 200, the elastic member 110 is compressed to store energy, and when the driving device 300 stops driving the elastic rod, the elastic rod is ejected toward the open end of the ejection channel 200 under the action of the elastic member 110, and the ejection end of the ejection rod 100 ejects the material entering from the feed port 210 to the outside of the ejection channel 200, and the open end of the ejection channel 200 enters the rotary kiln. The ejection device is also provided with a bracket 400, and the driving device 300, the ejection rod 100 and the ejection channel 200 are all arranged on the bracket 400, and the bracket 400 is used to support and fix the various components of the entire ejection device.

[0037] Among them, the driving device 300 includes a first driven wheel 310 and a second driven wheel 320, the first driven wheel 310 and the second driven wheel 320 are arranged front to back, the first driven wheel 310 and the second driven wheel 320 are connected by a chain 350, the first driven wheel 310 drives the second driven wheel 320 to rotate, and the chain 350 can be combined with the fixed block 120 to drive the ejection rod 100 to move toward the driving end, so that the elastic member 110 is compressed to store energy. Specifically, the first driven wheel 310, the second driven wheel 320, and the chain 350 connecting the first driven wheel 310 and the second driven wheel 320 are all located below the ejection rod 100. A fixed block 120 is provided below the driving end of the ejection rod 100, and a stop block 351 is provided above the chain 350. The stop block 351 can be combined with or separated from the fixed block 120. When the first driven wheel 310 and the second driven wheel 320 rotate, the chain 350 rotates to drive the stop block 351 to rotate. When the stop block 351 rotates to the closed end close to the ejection channel 200, the stop block 351 and the fixed block 120 are engaged. 20, the fixed block 120 moves with the stop block 351, and the fixed block 120 drives the ejection rod 100 to move toward the driving end to accumulate elastic potential energy. When the stop block 351 moves to the first driven wheel 310 and continues to rotate, the stop block 351 separates from the fixed block 120, and the ejection rod 100 moves toward the open end of the ejection channel 200 under the action of the elastic member 110, and the ejection end of the ejection rod 100 ejects and removes the material entering the ejection channel 200. In this way, the ejection rod 100 realizes a reciprocating motion in the elastic channel under the joint action of the stop block 351 and the elastic member 110.

[0038] Furthermore, a third driven wheel 330 is provided on the rotating shaft of the first driven wheel 310. The first driven wheel 310 and the third driven wheel 330 may be connected via a coupling. The third driven wheel 330 is connected to the driving wheel 340. The driving wheel 340 and the third driven wheel 330 are meshed and connected via a chain or a gear. The driving wheel 340 drives the third driven wheel 330 to rotate. The third driven wheel 330 drives the first driven wheel 310 to rotate. The first driven wheel 310 drives the second driven wheel 320 to rotate. The driving wheel 340 is connected to the power device 360. The power device 360 ​​may select a motor to provide power for the entire system. As a convertible embodiment, the power device 360 ​​may also use other power devices 360, such as a gasoline engine, a diesel engine, etc.

[0039] Preferably, the ejection end of the ejection rod 100 is provided with a push head 130, and the size and cross-sectional area of ​​the push head 130 can be set according to the size of the ejection channel 200 and the size of the material being pushed.

[0040] Preferably, the elastic member 110 can be configured as a spring, and the elastic coefficient of the spring and the number of the springs can be set as needed; of course, the elastic member 110 can also be configured as an elastic sheet, as long as the elastic member 110 can realize the accumulation of elastic potential energy.

[0041] like Figure 4 As shown, an opening and closing door 211 is provided on the feed port 210, and the opening and closing door 211 is connected to a gas-propelled pneumatic valve. The pneumatic valve can be used to open the opening and closing door 211. Specifically, a sensor switch 500 is provided on the bracket near the first driven wheel 310. When the stop block 351 moves with the chain to a position close to the sensor switch 500, the sensor switch is turned on, and the driving gas controlled by the sensor switch 500 reaches the pneumatic valve through a pipeline to control the opening of the pneumatic valve. When the stop block 351 is away from the sensor switch 500, the sensor switch 500 is closed, the corresponding pneumatic valve is closed, and the opening and closing door is closed under the action of the pneumatic valve, thereby realizing the automatic opening and closing of the opening and closing door.

[0042] When the reagent bottle filled with waste chemical reagents by the reagent filling device is conveyed to the feed port 210 through the conveyor belt, the opening and closing door of the feed port 210 is closed. When the ejection rod 100 moves toward the open end of the ejection channel 200, the opening and closing door is opened, just allowing the reagent bottle to enter the ejection channel 200. Under the action of the ejection rod 100, the reagent bottle containing the waste chemical reagent is ejected to the outside of the ejection channel 200. During the ejection process, the opening and closing door is automatically closed, thereby realizing the ejection of materials such as the reagent bottle containing the waste chemical reagent, and achieving the purpose of using the ejection channel 200 to feed the rotary kiln.

[0043] The ejection device for treating waste test bottles of the present invention is designed for the characteristics of chemical reagents with high purity, complex composition and high danger. It can isolate and dispose of the packaging of waste chemical reagents, and then pack the waste chemical reagents through an automated packing device. After packing, the reagent bottles containing waste chemical reagents are ejected into the kiln through the ejection device for treatment, so as to achieve relatively stable incineration of waste chemical reagents into the kiln, avoid severe impact on the kiln conditions, reduce the danger of the disposal process, and do not affect the simultaneous operation of other solid and liquid waste feeding systems. Improving the efficiency of hazardous waste disposal can expand the hazardous waste disposal capacity, and ensure that the chemical reagents are homogenized into the kiln and stably burned in the kiln.

[0044] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention.
