Description

Technical Field

[0002] The GMP principle requirement for drug stability testing is 25℃ / 60%RH humidity long-term stability test conditions. Therefore, the humidity maintenance of the test chamber is of great significance to drug stability testing. Among them, humidity regulation is achieved through the built-in humidity sensor in the test chamber, collecting data, adjusting it through the humidity controller (micro information processor), connecting the water tank heating element, and evaporating the water in the water tank to increase the humidity in the box or adjust the refrigeration solenoid valve to achieve dehumidification, so as to achieve the purpose of controlling the required humidity. After the water in the water tank evaporates, the pressure sensor will sense the falling water pressure signal, which is then transmitted to the control system, and the constant pressure water replenishment mechanism will replenish water in time within the constant water pressure range. At present, the water inlet of the constant pressure water replenishment mechanism used in the test chamber is mostly tap water, and there are impurities in the tap water. The pipeline of the constant pressure water replenishment mechanism of the test chamber is relatively thin. If the water impurities are not treated, it is easy to cause pipeline blockage.

[0020] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] The utility model discloses a constant pressure water replenishing mechanism for an experimental box, the overall structure of which is arranged as follows: Figure 1 As shown, it includes a variable frequency constant pressure water pump 6 and a split-type water storage treatment tank.

[0022] The variable frequency constant pressure water pump 6 is the core component for realizing constant pressure water replenishment. It follows the principle of the existing constant pressure water replenishment mechanism. The variable frequency constant pressure water pump 6 cooperates with the pressure sensor in the water tank of the experimental box. When the water pressure in the water tank drops, the controller will increase the operating speed of the variable frequency constant pressure water pump 6, increase the water flow rate, and thus increase the water pressure; when the water pressure in the water tank increases, the controller will reduce the operating speed of the variable frequency constant pressure water pump 6, reduce the water flow rate, and maintain the water pressure stable, thereby achieving a constant pressure water replenishment effect.

[0023] The invention takes into account that the water inlet of the existing constant pressure water replenishment mechanism of the experimental box is tap water, which may be mixed with impurities. Long-term use of tap water may cause the water replenishment pipeline to be blocked. Therefore, a water storage treatment box for pre-treatment of the water inlet is added.

[0024] like Figure 1 As shown, the water storage treatment tank is a split design structure, mainly including two parts: a rectangular water tank body 1, and a sealing cover 2 adapted to cover the water tank body 1. The sealing cover 2 is covered with the water tank body 1 by a sealing ring structure, and then locked and connected with the water tank body 1 by a spring lock 3, so that the sealing cover 2 can be conveniently opened or closed.

[0025] The sealing cover 2 is provided with an inlet valve 4 for tap water inlet. The inlet front end pipeline of the inlet valve 4 is connected with an inlet slag block 5 through a threaded structure. The inlet slag block 5 is a coarse filter, which is mainly used to intercept large particles of impurities and foreign objects. The probability of large particles of impurities and foreign objects appearing in tap water is low, and the setting of the inlet slag block 5 can play a role in risk prevention and control. In addition, the installation and setting with a threaded structure also has the advantage of convenient maintenance.

[0026] The main component for treating impurities in water in the water storage tank is the metal filter 13 disposed in the water tank body 1. Figure 2 and Figure 3 As shown, the metal filter 13 is arranged in a detachable manner, and combined with the split-type water storage treatment box, the metal filter 13 can be disassembled, washed and replaced, which is beneficial to maintaining the water filtration and treatment reliability of the constant-pressure water replenishment mechanism, ensuring the normal use of the constant-pressure water replenishment mechanism, and effectively reducing the probability of blockage in the water replenishment pipeline.

[0027] The detachable structure of the metal filter 13 is specifically provided as follows: Figure 3As shown, the metal filter 13 is fixed in the frame 14, and a T-shaped connecting plate 15 is formed on both sides of the frame 14. A rib 16 is fixed on the inner wall of the water tank body 1. The rib 16 is an integral structure of the water tank body 1 and protrudes from the inner wall surface of the water tank to increase the thickness at the current position, so that the T-shaped connecting plate 15 and the rib 16 can be locked and connected by bolts. In addition, a sealing gasket is sandwiched between the rib 16 and the T-shaped connecting plate 15 to improve the sealing performance and prevent a large amount of water from infiltrating into the filtered water chamber 1b from the front water chamber 1a.

[0028] Moreover, based on the setting of the metal filter mesh 13, the internal space of the water tank body 1 is divided into a pre-water chamber 1a and a post-filter water chamber 1b; accordingly, the water outlet pipe of the water inlet valve 4 extends into the pre-water chamber 1a, so that the tap water can completely enter the pre-water chamber 1a, and then enter the post-filter water chamber 1b after being filtered by the metal filter mesh 13.

[0029] A water outlet valve 8 is provided on one side of the water tank body 1, and the water outlet valve 8 is connected to the filtered water chamber 1b, and the water outlet valve 8 is also connected to the variable frequency constant pressure water pump 6 through the soft water pipe 9. As a result, the water in the filtered water chamber 1b flows out through the water outlet valve 8, and is sucked into the variable frequency constant pressure water pump 6 through the soft water pipe 9. The soft water pipe 9 is connected between the water pump inlet 11 of the variable frequency constant pressure water pump 6 and the water outlet valve 8; and the water pump outlet 12 of the variable frequency constant pressure water pump 6 is externally connected to the water tank of the test box, so that the variable frequency constant pressure water pump 6 sends the replenishing water to the water tank of the test box; according to the monitoring of the pressure sensor in the water tank of the test box, the variable frequency constant pressure water pump 6 performs constant pressure replenishing water.

[0030] In addition, in order to make the constant pressure water replenishment mechanism of the experimental box more compact, the variable frequency constant pressure water pump 6 is installed on the sealing cover 2 through the water pump bracket 6. And, in order to facilitate the installation of the constant pressure water replenishment mechanism of the experimental box on the rack, water tank mounting parts 17 are fixed at the front bottom and the back bottom of the water tank body 1.

[0031] In summary, for the constant-pressure water replenishment mechanism of the experimental box disclosed in the utility model, the replenishment water is pre-treated and filtered with a fine-mesh metal filter, thereby reducing the probability of scaling and clogging the pipeline. In addition, the water tank structure of the water storage treatment box is a rectangular parallelepiped, which is placed on a plane and fixed with a water tank mounting part. It is not easy to tip over and has water storage reliability. The water storage treatment box adopts a split design, and the sealing cover can be easily opened. The metal filter is a detachable structure, which is very convenient to remove for cleaning or maintenance and replacement, thereby helping to maintain the reliability of water filtration to ensure the normal use of the constant-pressure water replenishment mechanism.

[0032] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the technical solution of the present invention also belong to the protection scope of the present invention.
