Technical Field

[0001] This utility model relates to the field of pharmaceutical production technology, and more specifically, to a pharmaceutical equipment cleaning system. Background Technology

[0002] With the rapid development of the pharmaceutical industry, my country's pharmaceutical sector has responded to the national call to vigorously develop a pharmaceutical production innovation system and improve automation, gradually moving towards the technological modernization of pharmaceutical products. Major biopharmaceutical companies have successively established new R&D departments, setting up modern laboratories and experimental R&D projects. Among these efforts, the cleaning of pharmaceutical cleaning equipment is a crucial step in the preparation of drugs for these companies.

[0003] The cleaning machine system is a special system designed for pharmaceutical cleaning machine chambers. Its main optimization is to significantly reduce the time customers spend on cleaning equipment. Its main principle is to shorten the cleaning heating time and the drying time.

[0004] Existing rapid cleaning technology for cleaning machines can only meet the efficiency improvement requirements of simple loads, which leads to increased energy consumption of the cleaning machine, increased production costs for enterprises, and low heating efficiency per single load.

[0005] In conclusion, how to provide a cleaning machine system that can improve efficiency is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a pharmaceutical equipment cleaning system that can greatly shorten the heating time, reduce the energy required for heating, and help reduce costs.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A pharmaceutical equipment cleaning system includes a cleaning chamber, the bottom of which is provided with a drain pipe, and further includes:

[0009] A heat exchanger for heating the flushing fluid entering the cleaning chamber;

[0010] The water inlet pipe and the heat source pipe are both connected to the heat exchanger, and the water inlet pipe is connected to the cleaning machine chamber.

[0011] Furthermore, the water inlet pipe of this utility model includes:

[0012] The first water inlet pipe is connected to the heat exchanger;

[0013] The second water inlet pipe has one end connected to the heat exchanger and the other end connected to the cleaning machine chamber.

[0014] Furthermore, the second water inlet pipe is provided with a heating element to heat the rinsing fluid passing through the second water inlet pipe.

[0015] Furthermore, this utility model also includes:

[0016] A purge port is installed on the first water inlet pipe and is used to connect high-pressure gas.

[0017] Furthermore, in this utility model, the heat source pipeline includes:

[0018] A heat source inlet pipe is connected to the heat exchanger;

[0019] A heat source outlet pipe is connected to the heat exchanger and is used for the discharge of heat source.

[0020] Furthermore, this utility model also includes:

[0021] A first control valve is installed in the heat source inlet pipe.

[0025] Furthermore, the heat exchanger of this invention is a double-layer brazed plate heat exchanger.

[0026] Furthermore, in this invention, the rinsing fluid is purified water.

[0027] The pharmaceutical equipment cleaning system provided by this utility model connects both the inlet water pipe and the heat source pipe to a heat exchanger during use.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] The core of this invention is to provide a pharmaceutical equipment cleaning system that can greatly shorten the heating time, reduce the energy required for heating, and help reduce costs.

[0035] Please refer to Figures 1-2 A pharmaceutical equipment cleaning system includes a cleaning chamber 1 with a drain pipe at the bottom, a heat exchanger 2, a water inlet pipe 3, and a heat source pipe 4. The heat exchanger 2 is used to heat the rinsing fluid entering the cleaning chamber 1. The water inlet pipe 3 and the heat source pipe 4 are both connected to the heat exchanger 2, and the water inlet pipe 3 is connected to the inside of the cleaning chamber 1.

[0036] It should be noted that the pipes in the embodiments of this utility model can all be made of metal or PVC and other materials.

[0037] In addition, in this embodiment of the invention, the diameter of each pipe can be selected to match the size of the reserved interface in the cleaning machine chamber.

[0038] In use, both the water inlet pipe 3 and the heat source pipe 4 are connected to the heat exchanger 2, and the water inlet pipe 3 is connected to the cleaning machine chamber 1. That is, by passing the rinsing water into the water inlet pipe 3, the heat source for heat exchange is sent to the heat exchanger 2 through the heat source pipe 4, and heat exchange is achieved inside the heat exchanger 2, thereby increasing the temperature of the rinsing water and reducing the initial temperature at which the rinsing water needs to be heated later. This can significantly shorten the heating time of the cleaning machine and reduce the overall power consumption of the cleaning machine. At the same time, compared with traditional cleaning systems, this device can reduce the time cost of the cleaning machine by 20%, saving users a large amount of time costs and reducing the user's energy usage costs.

[0039] It should be noted that in this embodiment of the utility model, the cleaning chamber 1 is a water storage chamber, which is used to centrally heat the rinsing water after it has been heated.

[0040] In addition, the heat source in this embodiment of the invention can be the auxiliary heat energy generated in the user's production line, such as steam, industrial waste gas, waste liquid, etc.

[0041] Optionally, in some embodiments, the water inlet pipe 3 and the heat source pipe 4 may be made of metal or PVC.

[0042] Optionally, to improve the uniformity and heating efficiency of the rinsing water heating in the cleaning machine chamber 1, some embodiments further include a mixing component installed in the cleaning machine chamber 1. The mixing component includes a rotating shaft and a drive motor that drives the rotating shaft to rotate. Several blades are installed on the rotating shaft. Both the rotating shaft and the blades are hollow and connected. The blades are made of metal and have heating wires installed inside. By agitating the blades, the rinsing water in the cleaning machine chamber 1 is kept flowing. The blades have a heating function, which greatly increases the heating efficiency and heating uniformity.

[0043] In the above embodiments, the drive motor may be a stepper motor.

[0044] In the above embodiments, the blades are set at an inclined angle. The inclined blades can not only agitate the cleaning water laterally, but also make the cleaning water flow vertically, which is beneficial to improving heating efficiency and uniformity.

[0045] Optionally, in other embodiments, if the heat source is steam, a high-pressure jet nozzle can be installed at the bottom of the cleaning chamber 1, and the steam pipe can be directly connected to the high-pressure jet nozzle. Therefore, during use, high-temperature steam is directly sent into the cleaning chamber 1 through the high-pressure jet nozzle. At this time, the steam directly contacts the cleaning water to achieve the purpose of heat exchange with the cleaning water. When the high-pressure steam enters the cleaning water, a large number of bubbles are generated, which agitates the cleaning water and keeps the rinsing water in the cleaning chamber 1 flowing, greatly increasing the heating efficiency and heating uniformity.

[0046] In the above embodiments, the steam is first filtered before it enters the cleaning water. The filtration can be done using filter cotton or filter screen.

[0047] In the above embodiments, the high-pressure nozzle can be a nozzle with a one-way valve function, that is, when no steam enters, the high-pressure nozzle is closed to prevent the cleaning water from overflowing.

[0048] Please refer to Figures 1-2 In some embodiments, the water inlet pipe 3 includes a first water inlet pipe 301 and a second water inlet pipe 302. The first water inlet pipe 301 is connected to the heat exchanger 2, one end of the second water inlet pipe 302 is connected to the heat exchanger 2, and the other end of the second water inlet pipe 302 is connected to the cleaning machine chamber 1. That is to say, the water inlet pipe 3 is connected by two water inlet pipes, which is beneficial to adjust the position of the two water inlet pipes according to the different positions of the heat exchanger 2.

[0049] Optionally, in some embodiments, the heat exchanger may be any one of a shell-and-tube heat exchanger, a plate heat exchanger, a spiral plate heat exchanger, a plate-fin heat exchanger, or a combination thereof.

[0050] Optionally, in some embodiments, in order to increase heat exchange efficiency, the diameter of the cleaning water pipe entering the heat exchanger can be reduced, the length of the cleaning water pipe can be increased, and the flow rate can be controlled by a valve to greatly increase the contact time between the cleaning water and the heat source, thereby improving heat exchange efficiency and heat source utilization efficiency.

[0051] Optionally, in some embodiments, several sets of heat exchangers can be arranged sequentially, and the heat source can be passed through different heat exchangers to further improve the heat exchange efficiency.

[0052] Optionally, in some embodiments, a heating element is provided on the second water inlet pipe 302 to heat the flushing fluid passing through the second water inlet pipe 302. That is, a heating element can be installed on the second water inlet pipe 302 to further heat the flushing water and increase its initial temperature. Optionally, in the above embodiments, the heating element can be a heating tube, which is wrapped around the outside of the second water inlet pipe 302 to heat the flushing water.

[0053] In other embodiments, the heat source pipe 4 may be extended to the second water inlet pipe 302 to increase the initial temperature of the flushing water by increasing the contact time with the heat source pipe 4.

[0054] Please refer to Figures 1-2In some embodiments, a purge port 5 is also included. The purge port 5 is installed in the first water inlet pipe 301. The purge port 5 is used to connect compressed air to remove residual flushing fluid in the first water inlet pipe 301 and the second water inlet pipe 302. That is, after the flushing water is injected, the residual flushing fluid in the first water inlet pipe 301 and the second water inlet pipe 302 is blown away by high-pressure air by connecting compressed air to avoid affecting the next water intake.

[0055] Alternatively, in some embodiments, other high-pressure gases may also be connected.

[0056] Optionally, in some embodiments, the high-pressure gas is filtered before entering the first water inlet pipe 301 and the second water inlet pipe 302.

[0057] Please refer to Figures 1-2 In some embodiments, the heat source pipe 4 includes a heat source inlet pipe 401 and a heat source outlet pipe 402. The heat source inlet pipe 401 is connected to the heat exchanger 2, and the heat source outlet pipe 402 is connected to the heat exchanger 2 for discharging heat.

[0058] Please continue to refer to this. Figures 1-2 In some embodiments, a first control valve 6 is also included. The first control valve 6 is installed on the heat source inlet pipe 401. That is, the pressure at the heat source inlet pipe 401 is controlled by the first control valve 6 to avoid excessive pressure at the inlet pipe.

[0059] Optionally, in some embodiments, the first control valve 6 may be a solenoid valve.

[0060] In other embodiments, the first control valve 6 may be a pressure relief valve.

[0061] Please continue to refer to this. Figures 1-2 In some embodiments, a second control valve 7 is also included. The second control valve 7 is installed on the heat source outlet pipe 402. That is, the flow rate and velocity at the heat source outlet pipe 402 are controlled by the second control valve 7 to increase the residence time of the heat source inside the heat exchanger 2 and increase the heat recovery effect.

[0062] Optionally, in some embodiments, the second control valve 7 may be a solenoid valve.

[0063] Optionally, in some embodiments, the heat source is steam. In the pharmaceutical industry, steam is a common byproduct of heat, so its heat recovery and reuse helps reduce the user's production costs and reduce energy waste.

[0064] Optionally, in some embodiments, the heat exchanger 2 is a double-layer brazed plate heat exchanger 2, which is composed of multiple layers of corrugated thin plates stamped together. These plates are connected by vacuum brazing to form sealed flow channels. Hot and cold flushing fluids flow in the flow channels on both sides of the plates, exchanging heat through the plates. The corrugated plate design increases the turbulence of the flushing fluid, thereby improving heat transfer efficiency.

[0065] Optionally, in some embodiments, the rinsing water is purified water, which is water obtained by distillation, ion exchange, reverse osmosis or other suitable methods and contains no additives.

[0066] In other words, the key point of this utility model embodiment is that: heat exchange is achieved by using a heat source inside the heat exchanger 2 to increase the temperature of the rinsing water, thereby reducing the starting temperature at which the rinsing water needs to be heated later. This can significantly shorten the heating time of the cleaning machine and reduce the overall power consumption of the cleaning machine. At the same time, compared with traditional cleaning systems, this device can reduce the time cost of the cleaning machine by 20%, saving users a large amount of time costs and reducing users' energy usage costs.
