Description

Technical Field

[0001] This utility model relates to a medicine supply device, and more particularly, to an automatic medicine adding device. Background Technology

[0002] Currently, before processing brushed stainless steel coils, the stainless steel needs to be pulled through a cleaning tank. The cleaning tank contains a solution mixed with chemicals; when the brushed stainless steel comes into contact with the solution, the stains adhering to its surface dissolve into the solution. However, as the brushed stainless steel is continuously cleaned, the chemical concentration in the solution gradually decreases, and the cleaning effect weakens, requiring replenishment of the cleaning tank. Currently, the chemicals are mainly replenished manually, which has drawbacks such as untimely and inaccurate chemical addition. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide an automatic medicine adding device, which has the advantages of timely medicine addition and accurate medicine addition amount.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: an automatic chemical dosing device, including a mounting bracket for fixed connection with a cleaning tank, a chemical storage tank mounted on the mounting bracket, a chemical inlet at the upper end of the chemical storage tank, a chemical outlet at the lower end of the chemical storage tank, a dosing pump mounted on the mounting bracket, the inlet of the dosing pump being connected to an external storage tank containing the chemical via a water pipe, and a chemical replenishment pipe at the outlet of the dosing pump for replenishing the chemical. A pipe passes through the inlet of the medicine. A liquid level switch is installed in the medicine storage tank. The liquid level switch is electrically connected to the dosing pump. When the liquid level in the medicine storage tank is lower than the preset minimum liquid level value of the liquid level switch, the liquid level switch controls the dosing pump to start. When the liquid level in the medicine storage tank is lower than the preset maximum liquid level value of the liquid level switch, the liquid level switch controls the dosing pump to stop. A metering pump is installed on the mounting bracket. The inlet of the metering pump is connected to the medicine outlet through a water pipe.

[0005] Through the above technical solution, when cleaning sheet-like drawn stainless steel coils is required, the drawn stainless steel is controlled to pass through the cleaning tank while remaining submerged in the cleaning solution. Simultaneously, the speed at which the dosing pump supplies the chemical is controlled based on the moving speed of the drawn stainless steel. The dosing pump draws the chemical from the chemical storage tank into the cleaning tank, ensuring a consistently high concentration of chemical in the cleaning solution. When the chemical level in the storage tank falls below the preset minimum level of the level switch, the level switch activates the dosing pump, drawing the chemical from the storage tank into the storage tank. When the chemical level in the storage tank rises above the preset maximum level of the level switch, the level switch shuts off the dosing pump to prevent chemical overflow from the chemical inlet of the storage tank. In summary, the above-mentioned dosing device offers the advantages of timely and accurate chemical dosing.

[0006] Preferably, the mounting bracket includes a support base plate placed on the ground, a mounting column is provided at the upper end of the support base plate, a connecting arm is vertically provided at the side wall of the mounting column, a connecting plate is provided at the end of the connecting arm, the connecting plate is pressed and fixed to the side wall of the cleaning tank by a number of threaded parts, a support plate is provided at the upper end of the mounting column, the end of the support plate extends to the top of the cleaning tank, and the temporary storage tank for the medicine is provided at the upper end of the support plate.

[0007] With the above technical solution, the temporary storage tank for the chemical is positioned at the top of the support plate and above the cleaning tank. This prevents the chemical from spilling outside the cleaning tank when it is injected into the tank via the aforementioned adding device. The connecting plate is secured to the cleaning tank with several threaded fittings, making the assembly and disassembly of the adding device more convenient.

[0008] Preferably, the mounting bracket further includes an inclined support rod, one end of which is welded and fixed to the side wall of the mounting column, and the other end of which is welded and fixed to the lower end of the connecting arm.

[0009] Through the above technical solution, the support rod can be used to support and strengthen the connecting arm, thereby improving the connection stability between the above-mentioned adding device and the cleaning tank.

[0010] Preferably, the mounting bracket further includes an inclined reinforcing arm, one end of which is welded and fixed to the side wall of the mounting column, and the other end of which is welded and fixed to the lower end of the support plate.

[0011] Through the above technical solution, the reinforcing arm can be used to support and strengthen the support plate, thereby improving the structural strength of the support plate.

[0012] Preferably, two limiting columns are arranged side by side at the upper end of the support plate, and a plurality of limiting rings are welded and fixed between the two limiting columns. The plurality of limiting rings are distributed at equal intervals along the length direction of the limiting columns, and the medicine storage bucket is nested in the plurality of limiting rings.

[0013] Through the above technical solution, several limiting rings and two limiting columns work together to limit the position of the medicine storage container, preventing the medicine storage container from tilting or shaking during use.

[0014] Preferably, the upper end of the medicine storage container is fitted with a protective soft sleeve with a constricted opening, and the lower end of the medicine replenishment tube passes through the protective soft sleeve.

[0015] With the above technical solution, when adding medicine to the medicine storage tank through the dosing pump, the medicine is prone to splashing upwards. At this time, the protective soft shell with a constricted opening can block the splashed medicine, making it less likely for the medicine to fall outside the medicine storage tank and reducing the loss of medicine.

[0016] Preferably, the outlet of the metering pump is connected to an extension bucket via a water pipe. The extension bucket is flared from top to bottom, and an extension sleeve is provided at the lower end of the extension bucket. The lower end of the extension sleeve extends into the cleaning tank and is located above the liquid surface of the solution in the cleaning tank.

[0017] Through the above technical solution, the extension bucket is flared from top to bottom, which can be used to block the chemical discharged from the metering pump outlet and prevent chemical splashing. The extension sleeve also guides the chemical into the cleaning tank, further preventing chemical splashing.

[0018] Preferably, the outer wall of the extension bucket is provided with an external thread, and the inner wall of the extension sleeve is provided with an internal thread. The internal thread engages with the external thread for fixation. The inner wall of the extension sleeve is also provided with a limiting protrusion. The limiting protrusion is located at the end of the internal thread and is used to abut against the lower end of the extension bucket, thereby limiting the screw-in length of the extension bucket.

[0019] With the above technical solution, the extension bucket and the extension sleeve are connected by a thread, making disassembly and assembly more convenient. A limiting protrusion is provided on the inner wall of the extension sleeve to abut against the lower end of the extension bucket when the extension sleeve is screwed onto the outside of the extension bucket, thereby limiting the screwing length of the extension bucket.
