[0002] Water for injection refers to water that meets the requirements of the Chinese Pharmacopoeia under the item of Water for Injection. Water for injection is water obtained by distillation of distilled water or deionized water, so it is also called heavily distilled water.

[0003] In the preparation process of water for injection, it is crucial to ensure the purity of water quality. For example, a new energy-saving MVR equipment for preparing water for injection in the existing technology has a mesh-type barrier installed in its key component, the compressor. Through the multi-layer fence design, the particles in the water vapor constantly collide with the fence in the channel and are effectively blocked. It can efficiently filter out impurity particles in the water vapor, providing a strong guarantee for the preparation of high-purity water for injection.

[0004] However, after long-term use, the barrier body in the compressor is likely to cause a large number of particles to accumulate on the barrier body, and since the barrier body is arranged inside the compressor, it is inconvenient for the user to subsequently clean the particles on the screen.

DETAILED DESCRIPTION

[0028] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0029] First embodiment

[0030] Please refer to Figure 1 、 Figure 2 、 Figure 3 ,in, Figure 1 This is a schematic structural diagram of a first embodiment of an innovative energy-saving mechanical vapor recompression device for producing water for injection provided by the utility model; Figure 2 for Figure 1 The schematic diagram of the cross-sectional structure of the filter assembly shown; Figure 3 for Figure 2 The schematic diagram of the partition structure is shown in FIG. An innovative energy-saving mechanical vapor recompression device for producing water for injection comprises: a compressor body 1;

[0031] A first three-way pipe 2, which is fixedly installed at the input end of the compressor body 1, and one-way valves 21 are fixedly installed at both ends of the first three-way pipe 2;

[0032] Two mounting seats 3, the two mounting seats 3 are fixedly mounted on one end of the two one-way valves 21 respectively;

[0033] Two valves 51, the two valves 51 are fixedly mounted on one end of the two mounting seats 3 respectively;

[0034] A second three-way pipe 5, both ends of which are fixedly mounted on one end of the two valves 51;

[0035] Two filter assemblies 4, the two filter assemblies 4 are respectively fixedly installed on the top of the two mounting seats 3, and the two filter assemblies 4 include a vertical pipe 41, a sealing cover 42, a partition 43, a through hole 44, a first mesh plate 45 and a second mesh plate 46. The bottom of the vertical pipe 41 is fixedly installed on the top of the mounting seat 3, the sealing cover 42 is threadedly connected to the top of the outer side of the vertical pipe 41, the top of the partition 43 is rotatably connected to the bottom of the sealing cover 42, the through hole 42 is opened at the top of the partition 43, and the first mesh plate 45 and the second mesh plate 46 are both fixedly installed on both sides of the partition 43.

[0036] By installing a one-way valve 21 on the end surface of the first three-way pipe 2, water vapor can only enter the inner side surface of the first three-way pipe 2, thereby preventing water vapor from flowing in the opposite direction.

[0037] The interior of the vertical pipe 41 and the interior of the mounting seat 3 are connected.

[0038] The side surface of the partition plate 43 is in contact with the inner side surface of the vertical pipe 41 , and the side surfaces of the first mesh plate 45 and the second mesh plate 46 are also in contact with the inner side surface of the vertical pipe 41 .

[0039] The bottom of the partition 43 is clamped on the inner side of the limiting seat 31, so that the installation position of the partition 43 can be positioned.

[0040] The bottom of the inner side surface of the mounting seat 3 is fixedly mounted with a limiting seat 31 , and the bottom of the partition plate 43 is snap-connected to the inner side surface of the limiting seat 31 .

[0041] Since there are two filter assemblies 4, when it is necessary to clean the mesh plate on the inner side of one filter assembly 4, the user can close the valve 51 installed on the side of the filter assembly 4, and then open the valve 51 installed on the side of the other filter assembly 4 to allow the water vapor to pass through the other filter assembly 4 for filtration. In this way, the filter assembly 4 can be cleaned without stopping the machine, thereby avoiding affecting the normal use of the equipment.

[0042] The side of the partition 43 where the first mesh plate 45 and the second mesh plate 46 are staggered is shown in the attached diagram. Figure 2 As shown, through holes are provided on the top of the first mesh plate 45 and the second mesh plate 46, so that the gas can pass through the inner side of the vertical pipe 41 in an S-shape, and the particles can also collide with the top of the mesh plate to filter the particles in the water vapor.

[0043] The working principle of an innovative energy-saving mechanical vapor recompression device for producing water for injection provided by this utility model is as follows:

[0044] When in use, water vapor used to produce water for injection enters the inner side surface of the mounting base 3 through the second three-way pipe 5 and the valve 51, then flows through the inner side surfaces of the through holes opened on the multiple first mesh plates 45 and the second mesh plates 46, and causes particles in the water vapor to collide with the first mesh plates 45 and the second mesh plates 46, and then flows to the other side of the partition 43 through the through hole 44, and then passes through the first mesh plates 45 and the second mesh plates 46 on the other side of the partition 43 to filter the particles in the water vapor, and then passes through the one-way valve 21 and the first three-way pipe 2 into the interior of the compressor body 1, and then is ejected through the output end of the compressor body 1;

[0045] When it is necessary to clean the particles accumulated on the first mesh plate 45 and the second mesh plate 46, the user can rotate the sealing cover 42 to remove the sealing cover 42 from the top of the vertical tube 41, and then use the sealing cover 42 to drive the partition 43, the first mesh plate 45 and the second mesh plate 46 to move out from the vertical tube 41 and the inner side of the mounting seat 3, so that it is convenient for the user to clean the impurities accumulated on the first mesh plate 45 and the second mesh plate 46.

[0046] Compared with related technologies, the innovative energy-saving mechanical steam recompression device for producing water for injection provided by the present invention has the following beneficial effects:

[0047] Through the cooperation between the mounting base 3 and the filter assembly 4, after long-term use, the user only needs to rotate the sealing cover 42 to remove the sealing cover 42 from the top of the vertical pipe 41, which can drive the partition 43 and the multiple first mesh plates 45 and second mesh plates 46 installed on both sides of the partition 43 to move out from the inner side of the vertical pipe 41, so that the user can clean the impurities accumulated on the mesh plates conveniently.

[0051] The front side of the fixing frame 6 is rotatably connected to a protective door 61 .

[0052] The protective door 61 is disposed in front of the observation window 62 .

[0053] By installing the protective door 61 on the front of the observation window 62, the observation window 62 can be protected when no observation is being performed.

[0054] The working principle of an innovative energy-saving mechanical vapor recompression device for producing water for injection provided by this utility model is as follows:

[0055] During use, the user can open the protective door 61 and then observe the first mesh plate 45 and the second mesh plate 46 installed on the inner side of the vertical pipe 41 through the observation window 62 installed on the inner side of the fixing frame 6 .

[0056] Compared with related technologies, the innovative energy-saving mechanical vapor recompression device for producing water for injection provided by the present invention has the following beneficial effects:

[0057] By cooperating with each other through the fixed frame 6, the protective door 61 and the observation window 62, when in use, the user can conveniently observe the accumulation of impurities on the first mesh plate 45 and the second mesh plate 46 installed on the inner side of the vertical pipe 41 through the observation window 62, so that the user can clean them in time.
