Description

Technical Field

[0001] This utility model belongs to the technical field of cleaning devices, and in particular relates to a pharmaceutical cleaning device. Background Technology

[0002] Chemical cleaning devices utilize chemicals to clean objects (tanks, pipelines, etc.). During the cleaning process, a heating device is used to heat the chemicals to enhance the cleaning effect. Existing chemical cleaning devices contain chemicals in a tank, and the electric heating device is also located inside the tank, heating all the chemicals in the tank. Once the chemicals reach the set temperature, the delivery pump is activated, and the chemicals are sprayed out to clean the object with hot chemicals. However, existing chemical cleaning devices have excessively long heating times, cannot provide instant heating, and the chemical temperature cannot be easily adjusted during the cleaning process. Utility Model Content

[0003] To address the problems of excessively long heating times for chemicals in existing chemical cleaning devices and the inability to adjust the chemical temperature during the cleaning process, this invention discloses an adjustable chemical cleaning device. This invention enables instant heating of the chemical and allows for real-time temperature adjustment.

[0004] The technical solution provided by this utility model is: a drug cleaning device, including a drug storage tank and an adjustable heater. The adjustable heater includes an outer shell and an inner shell. An electric heater is provided in the middle of the outer shell. The inner wall of the outer shell is cylindrical. The upper inner side and the lower inner side of the outer shell are respectively provided with inwardly protruding sealing rings. The inner shell is located inside the outer shell and includes a conical section in the middle and straight sections at both ends of the conical section. The straight sections at both ends of the inner shell are respectively slidably sealed with the sealing rings at both ends of the outer shell, thereby forming a sealed cavity between the inner shell and the outer shell between the two sealing rings. Since the middle part of the inner shell is conical, the volume of the sealed cavity changes as the inner shell moves relative to the outer shell, thereby changing the amount of liquid contained in the sealed cavity. Since the heat provided by the electric heater is constant, the drug temperature of the overflow sealed cavity is adjustable by changing the drug dosage in the overflow sealed cavity. The upper end of the sealed cavity is connected to a liquid outlet, and the lower end of the sealed cavity is connected to a liquid inlet.

[0005] A further technical solution is as follows: Both ends of the outer shell are respectively provided with caps; the inner cavity of the inner shell is a hollow structure. During the sliding process of the inner shell relative to the outer shell, the hollow structure of the inner shell plays a role in balancing the air pressure or hydraulic pressure at both ends; a spring is provided between one end cap and the inner shell, and the spring is in a compressed state. A thrust mechanism is provided between the other end cap and the inner shell, and the thrust mechanism can push the inner shell to slide relative to the outer shell.

[0006] A further technical solution is that the thrust mechanism is a hydraulic cylinder.

[0007] A further technical solution is as follows: the cleaning device further includes a water storage tank, a liquid delivery pump, and a cleaning handle; the inlet of the liquid delivery pump is connected to the drug storage tank via a pipeline, and a drug inlet valve is installed on the pipeline; the inlet of the liquid delivery pump is also connected to the water storage tank via a pipeline, and a water inlet valve is installed on the pipeline; the outlet of the liquid delivery pump is connected to the inlet of the adjustable heater via a pipeline, and a valve A is installed on the pipeline; the outlet of the liquid delivery pump is also connected to the cleaning handle via a pipeline, and a valve B is installed on the pipeline; the outlet of the adjustable heater is connected to the cleaning handle via a pipeline, and a valve C is installed on the pipeline.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] 1. The adjustable heater of this utility model can heat the medicine and can heat it up instantly, with almost no waiting time.

[0010] 2. This utility model can adjust the temperature of the agent in the overflow sealing cavity by changing the dosage of the agent, thereby enabling cleaning with agents at different temperatures. Most importantly, the temperature adjustment process is continuous.

[0011] 3. The adjustable heater of this invention can also heat clean water, enabling the chemical cleaning device to provide hot water cleaning functionality. This makes the invention feature comprehensive functionality, simple structure, and convenient operation. Attached Figure Description

[0015] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0016] refer to Figure 1 This embodiment discloses a drug cleaning device, which specifically includes a drug storage tank 1, a water storage tank 4, an adjustable heater 2, a liquid delivery pump 10, and a cleaning handle 5.

[0017] refer to Figure 2 The adjustable heater 2 includes an outer shell 204 and an inner shell 210. An electric heater 205 is disposed in the middle of the outer shell 204. The inner wall of the outer shell 204 is cylindrical. The upper inner side and the lower inner side of the outer shell 204 are respectively provided with inwardly protruding sealing rings 203. The inner shell 210 is located inside the outer shell 204. The inner shell 210 includes a conical section in the middle and straight sections at both ends of the conical section. The straight sections at both ends of the inner shell 210 are respectively slidably sealed with the sealing rings 203 at both ends of the outer shell 204, thereby forming a sealed cavity 208 between the inner shell 210 and the outer shell 204 between the two sealing rings 203. Since the sealed cavity 208 contains or flows a small amount of medicine, and the electric heater 205 only heats the medicine flowing through the sealed cavity 208, the medicine can be heated to the set temperature in a very short time, thereby realizing the immediate use of the medicine cleaning device without waiting time. Because the inner shell 210 has a conical structure in the middle, the volume of the sealing cavity 208 changes as the inner shell 210 moves relative to the outer shell 204. This changes the amount of medicine contained in or flowing through the sealing cavity 208. Since the heat provided by the heater 205 is constant, the temperature of the medicine in the flowing sealing cavity 208 is adjustable by changing the amount of medicine. Most importantly, the temperature adjustment is continuous. The upper end of the sealing cavity 208 is connected to the outlet 209, and the lower end of the sealing cavity 208 is connected to the inlet 207. The liquid medicine in the medicine tank is pumped to the inlet 207 by the delivery pump 10, and the outlet 209 is connected to the cleaning handle 5.

[0018] The outer shell 204 has caps 201 at both ends. If the sealing ring 203 experiences a slight leak, the caps 201 provide a complete seal, encapsulating the entire inner shell 210 within the outer shell 204. The inner shell 210 has a hollow structure. During the sliding process of the inner shell 210 relative to the outer shell 204, the hollow structure of the inner shell 210 balances the air or hydraulic pressure at both ends. A spring 206 is positioned between one cap 201 and the inner shell 210, and the spring 206 is in a compressed state. A thrust mechanism is positioned between the other cap 201 and the inner shell 210. This thrust mechanism can push the inner shell 210 to slide relative to the outer shell 204, and can overcome the elastic force of the spring 206 to apply a thrust to the inner shell 210. Figure 2In this design, because the conical section in the middle of the inner shell 210 has a structure that is wider at the top and narrower at the bottom, if it is desired that the temperature of the agent flowing through the sealing cavity 208 is not high, the thrust mechanism does not exert force, keeping the inner shell 210 at the top of the sliding range; if it is desired that the temperature of the agent flowing through the sealing cavity 208 is higher, the thrust mechanism exerts force, pushing the inner shell 210 downward to reduce the flow rate of the agent in the sealing cavity 208, thereby resulting in a higher agent temperature. The thrust mechanism is a hydraulic cylinder 202.

[0019] Reference Figure 1 The connection method of this utility model is as follows.

[0020] The inlet of the liquid delivery pump 10 is connected to the medicine storage tank 1 via a pipeline, and a medicine inlet valve 7 is installed on the pipeline. The inlet of the liquid delivery pump 10 is also connected to the water storage tank 4 via a pipeline, and a water inlet valve 6 is installed on the pipeline. The outlet of the liquid delivery pump 10 is connected to the liquid inlet 207 of the adjustable heater 2 via a pipeline, and a valve A8 is installed on the pipeline. The outlet of the liquid delivery pump 10 is also connected to the cleaning handle 5 via a pipeline, and a valve B9 is installed on the pipeline. The outlet 209 of the adjustable heater is connected to the cleaning handle 5 via a pipeline, and a valve C3 is installed on the pipeline.

[0021] The first cleaning method: When cleaning with hot chemicals, open the chemical inlet valve 7, valve B9, and valve C3, and close the other valves.

[0022] The second cleaning method: When cleaning with hot water, open the inlet valve 6, valve B9, and valve C3, and close the other valves.

[0023] The third cleaning method: When cleaning with room temperature water, open the water inlet valve 6 and valve A8, and close the other valves.

[0024] This utility model achieves the pumping and cleaning of two liquids through a single liquid delivery pump 10, and realizes three cleaning methods through the setting of five valves. It has a simple structure, ingenious design, multiple functions, and strong practicality, and is worth promoting and using.
