A limiting frame and a connecting frame are fixed to the front end of the frame. A pair of limiting wheels are respectively provided in the connecting frame and the limiting frame for rotation through a rotating shaft. A guide rope is also fixed to the side of the liquid delivery pipe head.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 In this embodiment, a boiler cleaning agent detection sampling device includes a frame 1, a belt conveyor 2 is installed on the frame 1, and a pair of limit plates 3 extending to the top of the belt conveyor 2 are fixed on both sides of the frame 1. One end of the two limit plates 3 is bent outward to form a slope to facilitate the introduction of the agent bottle. The frame 1 is also fixed with a sample storage tank 4 and a sampling mechanism 5 for extracting the agent in the sample storage tank 4. When the agent bottle is transported to the sampling area by the belt conveyor 2, the sampling mechanism 5 can extract the sample into the agent bottle, and then send the agent bottle away through the belt conveyor 2 to complete the sampling, which is convenient for subsequent detection.

[0021] When the medicine bottle is transported to the sampling area by the belt conveyor 2, the sampling mechanism 5 can quantitatively extract the medicine into the medicine bottle for subsequent testing, as shown in the following example. Figure 2 As shown, the sampling mechanism 5 includes a metering pump 501 fixed on the frame 1, the liquid inlet of the metering pump 501 is connected to the bottom outlet of the sample storage tank 4 through a pipeline, and a lifting cylinder 502 is also fixed on the frame 1, and a liquid delivery pipe head 503 is fixed to the output shaft of the lifting cylinder 502, and the liquid outlet of the metering pump 501 is connected to the liquid delivery pipe head 503 through a pipeline and communicated with it.

[0022] Therefore, the metering pump 501 can extract the medicine in the sample storage tank 4 and send it into the liquid delivery pipe head 503, and the lifting cylinder 502 can drive the liquid delivery pipe head 503 to extend to the opening of the medicine bottle, so that the medicine can be extracted into the medicine bottle, and the pipe connecting the liquid outlet of the metering pump 501 and the liquid delivery pipe head 503 is a hose, therefore, the lifting cylinder 502 can freely drive the liquid delivery pipe head 503 to move up and down.

[0023] In addition, a material receiving trough 504 is also provided at the front end of the frame 1, and the material receiving trough 504 can move forward and backward. When the liquid delivery pipe head 503 moves downward, the material receiving trough 504 can move backward. A limiting frame 505 is fixed at the front end of the frame 1, and a fixed plate 506 is also fixed at the front end of the limiting frame 505. A limiting shaft 507 extending to the rear of the fixed plate 506 is fixed to the rear side of the material receiving trough 504. A movable plate 508 is fixed to the rear ends of a pair of limiting shafts 507. A return spring 509 is also sleeved on the outside and is located between the fixed plate 506 and the movable plate 508. A connecting frame 510 is also fixed on the frame 1. The lifting cylinder 502 is fixed on the connecting frame 510. A pair of limiting wheels 511 are respectively rotated in the connecting frame 510 and the limiting frame 505 through the rotating shaft. A guide rope 512 is also fixed on the side of the liquid delivery pipe head 503. The other end of the guide rope 512 passes around the two pairs of limiting wheels 511 in turn and is connected to the back of the material receiving trough 504.

[0024] Therefore, when the liquid delivery tube head 503 moves downward, one end of the guide rope 512 moves downward with the liquid delivery tube head 503, and the other end of the guide rope 512 drives the material receiving trough 504 to move backward, and the liquid delivery tube head 503 can be directly inserted into the opening of the medicine bottle, and the medicine is delivered into the medicine bottle through the liquid delivery tube head 503.

[0025] When the receiving trough 504 moves backward, the reset spring 509 is squeezed, and the receiving trough 504 moves more stably under the guidance of the limit shaft 507. After the sampling is completed, the liquid delivery tube head 503 moves upward, and the receiving trough 504 can be reset under the action of the reset spring 509. If there is residual liquid on the liquid delivery tube head 503, it can be directly dripped into the receiving trough 504. The bottom surface of the receiving trough 504 is tilted backward, so that the liquid dripped into the receiving trough 504 will not fall out from the front end opening thereof.

[0026] A positioning plate 513 is also fixed to the side of the receiving trough 504, and the stopping position of the medicine bottle is limited by the positioning plate 513 so that the liquid delivery pipe head 503 can be more accurately extended into the opening of the medicine bottle, effectively preventing the medicine from being accidentally spilled.

[0027] By adopting the above boiler cleaning agent detection sampling device, quantitative sampling of the agent is achieved for subsequent detection. The specific sampling method is as follows:

[0028] When the medicine bottle is transported to the sampling area by the belt conveyor 2, the positioning plate 513 accurately locates the stop position of the medicine bottle, and the lifting cylinder 502 is pushed out, and the liquid delivery pipe head 503 moves down. At the same time, one end of the guide rope 512 follows the liquid delivery pipe head 503 to move downward, and the other end of the guide rope 512 drives the receiving trough 504 to move backward. The liquid delivery pipe head 503 can be directly inserted into the opening of the medicine bottle, and the quantitative pump 501 can extract the medicine in the sample storage tank 4 and deliver the appropriate dose of medicine into the medicine bottle through the liquid delivery pipe head 503;

[0029] When sampling is completed, the liquid delivery tube head 503 moves upward, and the material receiving groove 504 can be reset under the action of the reset spring 509. If there is any residual liquid on the liquid delivery tube head 503, it can be directly dripped into the material receiving groove 504. The bottom surface of the material receiving groove 504 is tilted backward so that the liquid dripped into the material receiving groove 504 will not fall out from its front end opening.

[0030] The control method of the present invention is controlled by a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
