Description

Technical Field

[0001] This utility model relates to the field of dust removal technology, and in particular to a centralized dust removal system for pharmaceutical cleanrooms. Background Technology

[0002] Currently, dust removal systems in pharmaceutical cleanrooms mostly adopt a decentralized design, with each dust-generating point (such as pulverizers, mixing equipment, and packaging lines) equipped with a separate large-scale dust removal device. The dust removal air volume is not matched with the supply air volume and the indoor pressure difference, which presents the following problems:

[0003] a. Low efficiency: The filtration accuracy of decentralized dust collection equipment varies, making it difficult to ensure that the overall particle concentration in the cleanroom meets the GMP Class C / D requirements;

[0004] b. Complex operation and maintenance: Multiple devices require independent maintenance. Replacing filter media and cleaning accumulated dust is time-consuming and labor-intensive, and frequent operation can easily damage the clean environment;

[0005] c. Lack of monitoring: There is a lack of centralized monitoring methods, making it impossible to grasp the dust removal efficiency and system pressure difference changes at each dust-generating point in real time, and the response to abnormal situations is delayed;

[0006] d. Disadvantages include high energy consumption of air conditioning, high energy consumption of large dust removal air volume, and difficulty in controlling indoor cleanliness (dust spreads into the room causing secondary pollution). Utility Model Content

[0007] The technical problem this invention aims to solve is that current dust removal systems in pharmaceutical cleanrooms are inefficient, complex to operate and maintain, lack monitoring capabilities, and have high energy consumption.

[0008] The technical solution adopted by this utility model to solve its technical problem is: a centralized dust removal system for a medical cleanroom, including a centralized dust removal host, dust generation points and a pipeline network. The centralized dust removal host adopts a modular structure design. The pipeline network is composed of stainless steel sealed air ducts connecting the centralized dust removal host and each dust generation point. A differential pressure adaptive regulating valve is fixedly installed on the stainless steel sealed air duct near the dust generation point.

[0009] The centralized dust removal host includes a vertical body, an internal control frame installed inside the vertical body, a filter box installed on the side wall of the internal control frame, a detachable filter element installed inside the filter box, a top motor for driving the internal control frame, and a bottom dust collection box fixed to the bottom of the vertical body.

[0010] The differential pressure adaptive regulating valve includes a valve housing fixed at the connection end of the stainless steel sealed air duct and the dust generation point, an electrically controlled valve core installed inside the valve housing, and a pressure sensor module installed on the inner wall of the valve housing's input and output ports.

[0011] The vertical machine body has a side air inlet pipe fixedly mounted on its outer side for connecting to a stainless steel sealed air duct.

[0012] The vertical machine body has an internal isolation cover located at the side air intake pipe position on its inner wall.

[0013] The top of the vertical machine body is fixedly equipped with a top exhaust pipe.

[0014] The beneficial effects of this utility model are:

[0015] (1) The present invention provides a centralized dust removal system for a medical cleanroom, which is based on a differential pressure adaptive regulating valve fixedly installed at a position near the dust generation point in a stainless steel sealed air duct. The system automatically monitors the differential pressure change at each dust generation point and improves the dust removal efficiency by automatically adjusting the valve opening, thereby avoiding secondary pollution.

[0016] (2) The centralized dust removal host adopts a modular structure design, which facilitates filter replacement, reduces the cost and difficulty of later maintenance, and simplifies operation and maintenance;

[0017] (3) By adopting a rotating structure design, the internal dust can be removed by centrifugal force, giving it a self-maintenance function and reducing costs. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Figure 1, Figure 2 and Figure 3 The illustrated centralized dust removal system for a pharmaceutical cleanroom includes a centralized dust removal host 1, dust generation points 2, and a duct network. The centralized dust removal host 1 adopts a modular structure design. The duct network consists of stainless steel sealed air ducts 3 that connect the centralized dust removal host 1 and each dust generation point 2. Differential pressure adaptive regulating valves 4 are fixedly installed on the stainless steel sealed air ducts 3 near the dust generation points.

[0025] The entire system is centrally controlled by an intelligent control cabinet, which integrates a PLC controller, a touch screen, and a communication module. It supports remote monitoring and data storage, which is a current technology.

[0026] To facilitate centralized dust collection and filtration, the centralized dust collection unit 1 includes a vertical body 11, an internal control frame 12 installed inside the vertical body 11, a filter box 13 installed on the side wall of the internal control frame 12, a removable filter element 14 installed inside the filter box 13, a top motor 15 for driving the internal control frame 12, and a bottom dust collection box 16 fixed to the bottom of the vertical body 11.

[0027] External maintenance openings are provided on the side walls of both the vertical body 11 and the bottom-mounted dust collection box 16, which are fixed and sealed by sealing covers to facilitate later cleaning and maintenance.

[0028] The detachable filter cartridge 14 has a built-in multi-stage filtration unit with a filtration efficiency of ≥99.97%@0.3μm.

[0029] In order to adaptively adjust the flow rate according to the pressure difference, the pressure difference adaptive regulating valve 4 includes a valve housing 41 fixed at the connection end of the stainless steel sealed air duct 3 and the dust generation point 2, an electrically controlled valve core 42 installed inside the valve housing 41, and a pressure sensor module 43 installed on the inner wall of the inlet and outlet of the valve housing 41.

[0030] The electrically controlled valve core 42 is existing technology. It consists of a valve core installed inside the valve housing 41 and an adjustment motor installed outside the valve housing 41. The adjustment motor drives the valve core to rotate, thereby changing the flow rate of the differential pressure adaptive regulating valve 4, thus ensuring that the differential pressure at all regulating points remains consistent.

[0031] An existing air quality monitoring module can also be installed at the connection end of dust-generating point 2 as needed, so as to automatically open and close the differential pressure adaptive regulating valve 4, further reducing energy consumption.

[0032] To facilitate lateral air intake, a lateral air intake pipe 5 for connecting to a stainless steel sealed air duct 3 is fixedly mounted on the outer side of the vertical unit 11.

[0033] In order to ensure the lateral isolation effect in the filtering state, the inner wall of the vertical body 11 has an internal isolation cover 6 at the position of the lateral air intake pipe 5.

[0034] To further ensure the closure effect, a flip groove is provided on the inner wall of the inner isolation cover 6. A lateral closing cover is installed inside the flip groove via an electrically controlled support rod. The lateral closing cover is flipped by the electrically controlled support rod. When the electrically controlled support rod extends, it controls the lateral closing cover to fit tightly against the inside of the flip groove. This not only ensures lateral sealing but also locks the state of the inner control frame 12 to improve stability.

[0035] At the same time, when the electric control strut extends and retracts, it drives the side closing cover to flip, which can close the connection between the internal isolation cover 6 and the side air inlet pipe 5. At this time, the top motor 15 drives the internal control frame 12 to rotate at high speed, thereby using centrifugal force to throw the dust accumulated on the filter box 13 and the detachable filter element 14 outward, and then guide it down into the bottom dust collection box 16 along the lower opening of the internal isolation cover 6.

[0036] To facilitate top exhaust, a top-mounted exhaust pipe 7 is fixedly installed at the top of the vertical body 11.

[0037] The air drawn from the dust-generating point 2 will be drawn into the vertical unit 11 through the stainless steel sealed air duct 3, filtered by the removable filter element 14 inside the filter box 13, and then discharged upward into the top exhaust pipe 7.

[0038] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
