Description

Technical Field

[0001] The utility model relates to a disinfection gel filtering structure and belongs to the technical field of separation equipment. Background Art

[0002] Compared with liquid disinfectant, disinfectant gel has semi-solid and water-retaining properties. It is not easy to drip when applied. After application, it can form an application layer on the skin surface, which prolongs the disinfection effect time. The production raw materials of disinfectant gel contain thickeners that increase the viscosity of the system and form a gel state, such as carbomer, hydroxypropyl methylcellulose and other thickeners. The thickener has the characteristics of water absorption and swelling. The thickener that is not fully dispersed in the system during the production process of the disinfectant gel will form lumps and mix in the disinfectant gel. Therefore, the disinfectant gel needs to be filtered before filling. At present, the filter cartridge for filtering disinfectant gel is usually set in the pipeline, and most of the effective filtering surface of the filter cartridge is set along the flow section of the disinfectant gel. In the actual operation process, it is found that the speed of lumps accumulating on the filter surface set along the flow section is fast, which reduces the filtering capacity of the filter cartridge or even blocks it. Moreover, the lumps adhering to the filter surface need to be cleaned in time, otherwise bacteria will breed to form biofilms, causing the microorganisms of the production line to exceed the standard.

DETAILED DESCRIPTION

[0021] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0022] It should be noted that many specific details are described in the following description to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0023] like Figure 1-Figure 4 As shown in the figure, the disinfection gel filtration structure provided by the utility model includes a mounting tube 100 and a filter assembly 200. The mounting tube 100 is used to install the disinfection gel filtration structure provided by the utility model on the equipment for use. For example, a mounting hole is usually opened in the hopper cover 1 of the filling machine, and the mounting tube 100 is welded in the mounting hole.

[0024] Specifically, the filter assembly 200 includes an annular joint 210 and an outer filter cartridge 220 and an inner filter cartridge 230 with openings facing upward. The inner filter cartridge 230 is coaxially arranged inside the outer filter cartridge 220 , and the filter hole diameter of the outer filter cartridge 220 is smaller than the filter hole diameter of the inner filter cartridge 230 .

[0025] The annular joint 210 is sleeved on the outer side of the tube opening of the outer filter tube 220 , and a clamping groove 211 is provided on the upper end surface of the annular joint 210 .

[0026] The inner filter cartridge 230 includes a conical filter cartridge 231 and a cylindrical filter cartridge 232 connected to the bottom thereof. The diameter of the conical filter cartridge 231 gradually decreases from top to bottom.

[0027] During operation, the disinfection gel transported from the tank through the pipeline first enters the installation tube 100, and then enters the inner filter cartridge 230, where the larger lumps of matter carried in the disinfection gel are retained. The disinfection gel that passes through the inner filter cartridge 230 enters the outer filter cartridge 220, where the smaller lumps of matter in the disinfection gel are retained, thereby achieving filtration of the disinfection gel. In this way, the utility model achieves graded filtration of the disinfection gel by providing the inner filter cartridge 230 and the outer filter cartridge 220, so that the filtration load is graded by the inner filter cartridge 230 and the outer filter cartridge 220, thereby ensuring the filtration efficiency of the inner filter cartridge 230 and the outer filter cartridge 220.

[0028] Moreover, the disinfection gel entering the inner filter cartridge 230 is controlled by its flow direction and will rush to the bottom of the conical filter cartridge 231 and the cylindrical filter cartridge 232 with a large impact force. The disinfection gel rushing to the conical filter cartridge 231 will flush the trapped large agglomerates downward along the inclined surface of the conical filter cartridge 231, avoiding large-scale clogging of the filter holes of the conical filter cartridge 231, ensuring the effective filtering area of ​​the conical filter cartridge 231, and improving the filtering efficiency.

[0029] On the one hand, the cylindrical filter cartridge 232 can gather and contain the larger agglomerates washed down from the conical filter cartridge 231, thereby ensuring the effective filtering area of ​​the conical filter cartridge 231; on the other hand, compared with the filter cartridge arranged along the flow cross section, the filtering surface of the conical filter cartridge 231 in the utility model is arranged at an angle with the flow cross section of the disinfection gel, thereby increasing the filtering area. Under the effect of the above two factors, the filtering efficiency of the disinfection gel filtering structure provided by the utility model is effectively guaranteed.

[0030] In order to facilitate cleaning or replacement of the filter assembly 200, the filter assembly 200 is detachably connected to the mounting tube 100 in the utility model. The connection between the filter assembly 200 and the mounting tube 100 is preferably a threaded connection. Specifically, an internal thread can be provided at the lower pipe opening of the mounting tube 100, and an external thread matching the internal thread is provided on the outer ring surface of the annular joint 210.

[0031] In order to facilitate the separation of the outer filter cartridge 220 and the inner filter cartridge 230, in the utility model, an outer cartridge support edge 221 is arranged around the edge of the cartridge mouth of the outer filter cartridge 220, and an inner cartridge support edge 233 is arranged around the edge of the cartridge mouth of the conical filter cartridge 231. The inner cartridge support edge 233 is superimposed on the top of the outer cartridge support edge 221, and the inner cartridge support edge 233 and the outer cartridge support edge 221 are jointly embedded in the card slot 211.

[0032] During installation, the outer filter cartridge 220 and the inner filter cartridge 230 are nested and placed in the slot 211 of the annular joint 210 , and then the annular joint 210 is rotated and tightened on the lower pipe opening of the installation pipe 100 .

[0033] In a preferred embodiment, the lower portion of the mounting tube 100 is configured as a stepped hole with an increased diameter, and an internal thread is disposed in the stepped hole.

[0034] Furthermore, when the inner cylinder support edge 233 and the outer cylinder support edge 221 are placed in the slot 211, the top surface of the inner cylinder support edge 233 is higher than the top surface of the annular joint 210. With this arrangement, when the annular joint 210 is tightened with the mounting pipe 100, the inner cylinder support edge 233 will be squeezed by the connecting step, thereby achieving the effect of fixing the outer filter cartridge 220 and the inner filter cartridge 230.

[0035] Typically, a connection flange 110 is fixed to the upper pipe opening of the installation pipe 100 to facilitate connection with a pipeline.
