[0038] In a preferred embodiment, the dosing barrel 110 is a PE plastic barrel. Since the dosing barrel 110 needs to be loaded with acidic or alkaline liquid medicine, the dosing barrel 110 made of PE material can avoid being overlooked by the acid and alkali liquid, making the dosing device more stable to use.

[0039] In a preferred embodiment, the pump body 210 is a peristaltic pump, which can be used to transport liquids.

[0040] In a preferred embodiment, the first switch valve 310 is a discharge ball valve.

[0041] In a preferred embodiment, a sealing ring is provided between the sealing cover 120 and the dosing port 110B. By providing a sealing ring between the sealing cover 120 and the dosing port 110B of the dosing barrel 110, the sealing performance between the sealing cover 120 and the dosing port 110B is improved, thereby preventing the liquid in the dosing barrel 110 from volatilizing into the air through the dosing port 110B, avoiding air pollution, ensuring the safety of workers, and having the advantage of less environmental pollution.

[0042] In a preferred embodiment, the sealing cover 120 is provided with at least two buckles, and the dosing port 110B is provided with at least two connecting buckles, and the buckles and the connecting buckles are detachably connected. By providing a buckle on the sealing cover 120, the buckle is buckled on the connecting buckle of the dosing barrel 110 when sealing is required, so that the sealing cover 120 is tightly connected with the dosing barrel 110, and the dosing port 110B is sealed. The buckle connection method has the advantage of convenient operation. In other embodiments, the sealing cover 120 and the delivery port 110D can also be connected by a threaded pair. By providing a threaded pair connection between the sealing cover 120 and the dosing barrel 110, the connection between the two is tighter and the sealing stability is better.

[0043] In a preferred embodiment, Figure 2 and Figure 3 As shown, a discharge portion 111 is provided at the bottom of the medicine adding barrel 110, and the discharge portion 111 is the end of a funnel-shaped structure, that is, a downward conical structure, and a discharge port 110C is provided at the lowest end of the discharge portion 111. Since some liquid medicine may remain in the medicine adding barrel 110 after the medicine adding device is completed and needs to be processed, by providing the discharge portion 111 at the bottom and providing the discharge port 110C at the lowest end of the discharge portion 111, the discharge portion 111 with a funnel-shaped structure automatically gathers the residual liquid medicine in the barrel to the discharge port 110C, and then automatically discharges from the discharge port 110C, without the need for manual pouring of the residual liquid, and the discharge is cleaner and more thorough, which has the advantage of being easy to use.

[0044] In a preferred embodiment, Figure 2 and Figure 3 As shown, a platform portion 112 is also provided at the bottom of the medicine adding barrel 110. The platform portion 112 is a horizontally arranged end portion. The bottom end of the first delivery pipe 220 extends to the top of the platform portion 112. The discharge portion 111 and the platform portion 112 are arranged side by side at the bottom of the medicine adding barrel 110. By providing the platform portion 112, the bottom end of the first delivery pipe 220 extends to the surface of the platform portion 112. Then, the lowest liquid level of the medicine liquid in the medicine adding barrel 110 is the horizontal plane of the platform portion 112, which is convenient for judging the dosage.

[0045] Furthermore, if Figures 1 to 3As shown, the dosing device further includes a liquid level switch 400, the platform portion 112 is provided with a detection port 110E, the liquid level switch 400 is installed at the detection port 110E, and the liquid level switch 400 is electrically connected to the pump body 210. By arranging the liquid level switch 400 on the platform portion 112, it is detected whether the liquid level in the dosing barrel 110 reaches the platform portion 112, and when it is detected that the liquid level reaches the platform portion 112, the pump body 210 is controlled to automatically close, thereby realizing automatic stop of dosing, reducing manual operation errors, and having the advantage of high degree of automation.

[0046] In a preferred embodiment, Figures 1 to 3 As shown, the dosing device further includes a filter 510, and a filter port 110F is further provided on the top of the dosing barrel 110, and the filter 510 is installed at the filter port 110F. Since the liquid medicine loaded in the dosing barrel 110 usually volatilizes, when the sealing cover 120 is opened after the dosing barrel 110 is loaded with the liquid medicine, irritating gas may be ejected, causing harm to the staff. Therefore, by providing the filter port 110F on the top and installing the filter 510 to filter the gas in the barrel and then discharge it into the air, it is prevented that harmful gas is ejected when the sealing cover 120 is opened to injure the staff and pollute the air.

[0047] Furthermore, if Figures 1 to 3 As shown, the filter 510 further includes a second switch valve 520, which is installed at the filter port 110F, and the filter 510 is connected to the second switch valve 520. Specifically, the second switch valve 520 is a gas ball valve. The filter 510 is connected through the second switch valve 520, and the filter port 110F can be switched on and off, and opened when exhaust is required, so that the gas in the accommodating chamber 110A is filtered and discharged through the filter 510.

[0048] In a preferred embodiment, Figure 1 and Figure 2 As shown, the dosing barrel 110 further includes a first adapter 240, a second adapter 410 and a third adapter 530. The first adapter 240 is installed at the delivery port 110D, and the pump body 210 is connected to the first adapter 240; the second adapter 410 is installed at the detection port 110E, and the liquid level switch 400 is connected to the second adapter 410; the third adapter 530 is installed at the filter port 110F, and the second switch valve 520 is connected to the third adapter 530. By setting the first adapter 240 to connect the pump body 210, the sealing degree between the pump body 210 and the delivery port 110D is guaranteed, the second adapter 410 is connected to the liquid level switch 400, so as to ensure the sealing degree between the liquid level switch 400 and the detection port 110E, and the third adapter 530 is connected to the second switch valve 520, so as to ensure the sealing degree between the second switch valve 520 and the filter port 110F, so that the dosing device has good sealing performance and avoids leakage of harmful gas.

[0049] In a preferred embodiment, Figures 1 to 3 As shown, the dosing device further includes a support frame 600, and the dosing barrel 110 is installed on the support frame 600. Since the bottom of the dosing barrel 110 is a conical structure, by placing the dosing barrel 110 on the support frame 600, the dosing barrel 110 can be stably placed, so that the conveying function and the discharge function of the dosing device can be stably used.

[0050] The dosing device described in the embodiment of the present application has the following beneficial effects:

[0051] 1. By providing the sealing cover 120 to the dosing port 110B, after the acid and alkali liquid is added, the dosing port 110B will be sealed to prevent the liquid from volatilizing and air pollution. In addition, the residual liquid can be automatically discharged through the first switch valve 310 and the discharge pipe 320, reducing the operation process, with the advantages of less pollution and convenient use.

[0052] 2. By arranging a discharge portion 111 at the bottom and a discharge port 110C at the lowest end of the discharge portion 111, the discharge portion 111 with a funnel-shaped structure makes the residual liquid in the barrel automatically gather to the discharge port 110C, and then automatically discharge from the discharge port 110C, without the need for manual pouring out of the residual liquid, and the discharge is cleaner and more thorough, which has the advantage of being easy to use.

[0053] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
