DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0026] As Figures 1 to 5As shown in the figure, the low-level drainage device of the pharmaceutical equipment in this embodiment includes a frame 1, a platen cover 2, a platen 21, and an isolator chamber 3. The platen cover 2 is laid on the platen 21, and the platen 21 is arranged on the top plate 11 of the frame 1. A spacer 5 for tilting the platen 21 from one end to the other is provided on the top plate 11, and the platen cover 2 has the same inclination angle as the platen 21. The top of the spacer 5 has an inclined portion, and the platen 21 is supported on the inclined portion. The isolator chamber 3 is arranged on the platen cover 2, and the platen cover 2 forms the bottom wall of the isolator chamber 3. A drain port 41 is provided at the lower end of the platen cover 2. A plurality of mounting pads 6 are provided on the top plate 11. Each mounting pad 6 passes through the platen 21 and the platen cover 2 in sequence and extends out of the platen cover 2. A sealed connection is provided between each mounting pad 6 and the platen cover 2.

[0027] When the isolator chamber 3 is cleaned, the cleaning water falls on the platen cover 2, and the water flows from the high end to the low end on the platen cover 2 by the action of gravity. Figure 1 As shown by the arrow e, finally, it flows out through the drain port 41 at the lower end. Since the spacer enables the platen cover 2 to be inclined, the water on the platen cover 2 can be drained completely, so that there will be no liquid accumulation on the platen cover 2. Not only the water is drained cleanly, but also the drainage efficiency is improved, and the time required for drainage is saved. Among them, the inclined portion at the top of the spacer 5 and the platen 21 can be in surface contact fit, which improves the installation stability of the platen 21 and the platen cover 2; and the platen cover 2 is installed on the frame 1 through the spacer 5, and the platen cover 2 will not form a suspended structure, which is stable and reliable. In addition, by laying the platen cover 2 on the platen 21, the platen cover 2 is preferably a whole panel, avoiding the water leakage problem caused by the gaps brought by the installation of the platen 21. The inclination angle of the platen cover 2 is adjusted by the inclined portion of the spacer 5. The mounting pads 6 are horizontally installed, and both the top and the bottom are horizontally arranged, which does not affect the horizontal installation of other equipment and does not require machining on the machine tool, which can greatly reduce the processing time and processing cost.

[0028] In this embodiment, in order to facilitate the installation of the platen cover 2, the spacer includes a first spacer 51 and a second spacer 52. The tops of the first spacer 51 and the second spacer 52 are respectively provided with a first inclined portion and a second inclined portion. The first spacer 51 and the second spacer 52 are respectively arranged at both ends of the top plate 11. The height of the first spacer 51 is greater than the height of the second spacer 52. The setting of the height difference makes one end of the platen cover 2 tilt towards the other end. The two ends of the platen cover 2 are respectively supported on the first inclined portion and the second inclined portion. The settings of the first inclined portion and the second inclined portion make the supporting part between the platen cover 2 and the first spacer and the second spacer be in surface contact. Among them, the high and low points are controlled by a fixed height difference through high and low spacers, and the height is controllable, making its versatility very strong.

[0029] In this embodiment, the thickness of the platen 21 is greater than that of the platen cover 2, providing a supporting function. The platen cover 2 is connected to the first cushion block 51 and the second cushion block 52 through the platen 21, fixing the platen cover 2 and the platen 21 on the top plate 11 of the frame 1. Specifically, one end of the platen 21 is supported on the first inclined portion of the first cushion block 51, and the other end is connected to the second cushion block 52 through a lapping step (see the lapping method of the positive step m and the negative step n in the appendix). This structure can ensure the connection between the platen 21 and the second cushion block 52, and at the same time ensure that the top surface of the platen 21 is flush with the inclined surface of the second inclined portion. Thus, the top surface of the platen 21, the inclined surface of the first inclined portion, and the inclined surface of the second inclined portion are located in the same inclined plane. The platen cover 2 is laid on this inclined plane. The platen cover 2 is a whole panel, and the water in the isolator chamber 3 falling on the platen cover 2 will not leak, but only flow from the high end to the drain port 41 at the low end. Figure 3 In the lapping method of the positive step m and the negative step n). This structure can ensure the connection between the platen 21 and the second cushion block 52, and at the same time ensure that the top surface of the platen 21 is flush with the inclined surface of the second inclined portion. Thus, the top surface of the platen 21, the inclined surface of the first inclined portion, and the inclined surface of the second inclined portion are located in the same inclined plane. The platen cover 2 is laid on this inclined plane. The platen cover 2 is a whole panel, and the water in the isolator chamber 3 falling on the platen cover 2 will not leak, but only flow from the high end to the drain port 41 at the low end.

[0030] In this embodiment, the cushion block further includes a third cushion block 53. The top of the third cushion block 53 has a third inclined portion, and the platen 21 is supported on the third inclined portion. The third cushion block 53 is a strip-shaped inclined plane block, strengthening the support for the platen 21 and improving the installation strength of the entire platen 21 and the platen cover 2. Preferably, 3 third cushion blocks 53 are provided, 2 first cushion blocks 51 are preferably provided, and 1 second cushion block 52 is preferably provided, and its length is the same as the width of the top plate 11.

[0031] In this embodiment, after the platen 21 and the platen cover 2 are connected by bolts, full welding is performed to prevent water leakage. The platen 21 is connected to the first cushion block 51, the second cushion block 52, and the third cushion block 53 by bolts.

[0032] In this embodiment, a water collecting chamber 4 is provided at one end of the isolator chamber 3. The water collecting chamber 4 is provided at the lowest end of the platen cover 2 and is communicated with the isolator chamber 3. The bottom wall of the water collecting chamber 4 is not higher than the lowest end of the platen cover 2. In this embodiment, the bottom wall of the water collecting chamber 4 is smoothly connected to the lowest end of the platen cover 2, and their inclination degrees are the same. The drain port 41 is provided on the bottom wall of the water collecting chamber 4. The water collecting chamber 4 can quickly collect the cleaning water and discharge it through the drain port 41.

[0033] In this embodiment, through holes 201 for multiple mounting cushion blocks 6 to pass through are correspondingly provided on the platen cover 2, and the mounting cushion blocks 6 and the platen cover 2 are sealed by welding. The mounting cushion blocks 6 are used to mount other mechanisms.

[0034] Specifically, taking the example that the column installation pad 7 is provided on the top plate 11, the column installation pad 7 also belongs to one type of the installation pad 6. The column installation pad 7 passes through and extends out of the platen cover 2 for installing the column 8. The bottom of the column installation pad 7 is provided with a first positioning convex portion 71, and the top plate 11 is provided with a first positioning notch 101 that can cooperate with the first positioning convex portion 71. The first positioning convex portion 71 and the first positioning notch 101 adopt a small clearance fit to improve the positioning accuracy and installation accuracy of the column installation pad 7 and the top plate 11.

[0035] Furthermore, the bottom of the column 8 is provided with a second positioning convex portion 81, and the column installation pad 7 is provided with a second positioning notch 72 that can cooperate with the second positioning convex portion 81. The second positioning convex portion 81 and the second positioning notch 72 adopt a small clearance fit to improve the positioning accuracy and installation accuracy of the column 8 and the column installation pad 7. The column installation pad 7 and the platen cover 2 are sealed by welding; the column 8 and the column installation pad 7 are sealed by a sealing ring 82, and the double sealing ensures no water leakage. The column 8 is detachably installed, which is convenient for subsequent maintenance and installation. This way of pre-installing the installation pad 6 in advance can ensure that all parts are processed offline, completed by welding after assembly, and do not need to be processed on a machine tool anymore, which can greatly reduce the processing time and processing cost.

[0036] It should be noted that, except for this embodiment, only the first pad 51 can be set, without setting the second pad 52 and the third pad 53, or only the first pad 51 and the third pad 53 can be set.
