Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical equipment technology, and in particular to a collection device for pharmaceutical ultrafine powders, specifically an isolation collector for a transverse elliptical structure filter. Background Technology

[0002] The filter bag separator mainly consists of an upper housing, a lower housing (hopper), a powder cleaning system, and a material barrel. The upper housing incorporates a pulse backflushing system, and the middle housing is fitted with high-density filter cloth, effectively achieving gas-solid separation. Utilizing the principle of filter bag separation, the separator collects qualified residual powder and performs gas-solid separation, resulting in a total powder collection rate of ≥99.5%.

[0003] The filter bags in bag filters are typically vertical. Due to the height requirements of cleanrooms in pharmaceutical plants, which are mostly between 2700-2800mm, the height of the filter bags within the central housing is affected, thus impacting the filtration area. This is especially true when gas-solid separation for powder collection requires filters with a larger filtration area, necessitating an increase in the height of the central housing. Some pharmaceutical plants have raised their building heights during the initial design phase. However, the height of older pharmaceutical plant buildings is already fixed and difficult to modify, which complicates the design of a suitable bag filter collector. Utility Model Content

[0004] This invention provides an isolation collector for a transversely elliptical filter structure, which increases the filtration area of ​​the filter bags while maintaining the same number of filter bags.

[0005] To achieve the purpose of this utility model, the technical solution adopted is: a separator collector for a transverse elliptical structure filter, including a housing assembly, a material bucket assembly, a bag cavity welded frame, a bag mesh fixing plate, an elliptical bag mesh assembly, and a discharge funnel. The bag cavity welded frame is installed on the outer side of the housing assembly. The housing assembly is connected to the material bucket assembly through the discharge funnel.

[0007] As an optimized solution of this utility model, the venturi assembly includes a venturi fixing plate and venturi tubes. The two venturi tubes and the venturi fixing plate form a whole, and the intersection of the two venturi tubes forms a common cutting surface.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this patent clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0023] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] It should be noted that the terminology used herein is for the purpose of describing particular implementations only and is not intended to limit the exemplary implementations according to this utility model.

[0025] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, and in all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other example values ​​of the exemplary embodiments may have different values.

[0026] like Figure 1-3 As shown, this utility model discloses an isolation collector for a transversely elliptical filter structure, including a housing assembly 1, a material tank assembly 2, a bag chamber welded frame 3, a bag mesh fixing plate 4, an elliptical bag mesh assembly 5, and a discharge funnel 6. The bag chamber welded frame 3 is installed on the outer side of the housing assembly 1. The housing assembly 1 is connected to the material tank assembly 2 via the discharge funnel 6. The bag mesh fixing plate 4 is located at the junction of the bag chamber welded frame 3 and the housing assembly 1. The elliptical bag mesh assembly 5 is transversely installed on the frame formed by the bag mesh fixing plate 4. By transversely configuring the filter bag structure, the height problem of the collector is solved, and the side-mounted housing filter bag replacement structure facilitates assembly and maintenance.

[0027] like Figure 4As shown, the elliptical bag filter assembly 5 includes a bag filter housing 51, a bag filter fixing ring 52, a venturi assembly 53, and an elliptical filter bag. The elliptical filter bag is connected to the venturi assembly 53 by rivets, and the elliptical filter bag is installed inside the bag filter housing 51 through the bag filter fixing ring 52. Using elliptical filter bags increases the filtration area of ​​the filter bags when the number of filter bags is the same.

[0028] like Figure 5 As shown, the Venturi assembly 53 includes a Venturi fixing plate 531 and two Venturi tubes 532. The two Venturi tubes 532 and the Venturi fixing plate 531 form a whole, and the intersection of the two Venturi tubes 532 forms a common cutting surface. The Venturi assembly 53 is disposed at the opening of the elliptical filter bag. Two Venturi tubes are provided at the inlet of the elliptical filter bag to increase the impact velocity of the pulsed gas, facilitating the blowing off of powder adhering to the filter bag.

[0029] An additional layer of silk fabric is added to the outside of the oval filter bag. This silk fabric layer helps reduce dust adhesion to the filter cloth and creates a filtration layer on the filter bag, improving dust collection efficiency.

[0030] The transversely elliptical filter collector also includes a quick-release clamp 7, a nozzle 8, and a pressure plate 9. The quick-release clamp 7 is installed at the bottom of the welded frame 3 of the filter bag cavity, the nozzle 8 is installed on the quick-release clamp 7, and the pressure plate 9 is vertically installed on the nozzle 8. The filter bag fixing plate 4 is fixed in the welded frame 3 of the filter bag cavity by the pressure plate 9. This structure enables the transverse installation of the elliptical filter bag.

[0031] After the gas containing powder enters the separator collector, it first enters the housing assembly. Due to the internal pulse-jet backflushing system and high-density filter cloth, solid particles are intercepted by the elliptical filter bags as the gas passes through, while the cleaned gas is discharged through the filter bags. When the pulse-jet backflushing system operates, compressed air is injected at high speed through a venturi tube onto the surface of the filter bags, using the resulting impact force to shake off the dust from the surface of the filter bags. An additional layer of silk fabric protective sleeve on the outside of the elliptical filter bags not only reduces the chance of direct contact between dust and the filter cloth, lowering the possibility of adhesion, but also forms an extra filtration layer, further improving the collection efficiency and quality of the powder. The powder intercepted by the filter bags enters the material tank assembly for collection through the discharge funnel.

[0032] This utility model relates to a transverse elliptical structure filter separator. While meeting the required filtration area, it solves the height issue of the collector. The side-mounted housing and filter bag replacement structure facilitate safe operation by employees. A Venturi tube at the filter bag opening facilitates the flushing of powder adhering to the filter bag surface by pulsed gas. The double-layer filter bag design creates a filtration layer, improving the powder collection rate. After gas-solid separation, the dust content in the gas is 10 mg / Nm³. 3 .

[0033] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
