Description

TECHNICAL FIELD

[0001] The utility model relates to the field of decomposition filter, especially a decomposition filter translation structure and isolator. BACKGROUND

[0002] The existing sterilization system is mainly applied to the overall sterilization treatment of the isolator cavity to ensure the sterile state of the cavity environment. However, these systems generally have a significant problem that the sterilization process takes too long, which directly affects the production efficiency and operation cycle of the equipment. In the prior art, the structure design of the sterilization system has some deficiencies. In particular, in the residual discharge stage, the decomposition filter needs to be translated to below the return air outlet to complete the residual discharge process. However, due to the insufficient design of the cylinder guide rail to withstand a large pressure, it is easy to cause the guide rail to bend during operation, thereby shortening the service life of the equipment and requiring frequent replacement of the cylinder. In addition, the design of such a decomposition filter requires a large space area, so it is difficult to apply in situations where the space is small or the cavity is narrow.

[0003] On the other hand, some existing technical solutions have another problem in the sterilization stage. During the process of the fan pumping hydrogen peroxide into the cavity, the decomposition filter will block in the air duct, so that the hydrogen peroxide needs to pass through the surface of the decomposition filter in a large area. This situation can cause the concentration of hydrogen peroxide to be greatly reduced when passing through the decomposition filter, so that the required sterilization concentration cannot be reached, affecting the sterilization effect and not meeting the strict sterilization requirements.

[0004] Therefore, there is an urgent need in the market for a new sterilization system structure that can shorten the sterilization time, improve the production efficiency of the equipment, and at the same time have better structural stability, be suitable for cavities of different sizes, and ensure that the concentration requirements of the sterilization process are met.

Therefore, the following description should be understood as widely known by those skilled in the art, and not as a limitation on the present application.

[0026] It should be noted that in this paper, relationship terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between the entities or operations. Moreover, the terms "include", "contain" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment.

[0027] The following paragraphs describe the present invention in more detail by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the drawings are greatly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention.

[0028] First, as Figure 1 As shown, the utility model provides a decomposition filter translation structure, including two slide rails 1, a filter assembly and a push assembly;

[0029] The slide rails 1 are respectively placed on two opposite sides of the filter assembly, and the filter assembly can move along the slide rails 1;

[0030] The pushing assembly includes a cylinder 2 and a transmission member 5. The cylinder 2 is fixedly placed on the lower surface of one of the slide rails 1. The transmission member 5 is sleeved on the cylinder 2, and one end of the transmission member is fixedly connected to the side wall of the filter assembly through a connecting member 6 to drive the filter assembly to move along the slide rail 1.

[0031] Furthermore, the connector 6 is connected to the filter assembly via threads.

[0032] Specifically, the slide rails 1 are guide rails installed on both sides of the filter assembly, providing a defined path for the filter assembly. The slide rails 1 ensure that the filter assembly maintains a straight line during movement, preventing deviation. The filter assembly is the main component of the filter, responsible for completing the filtration process. As needed, the filter assembly may need to be removed or repositioned for maintenance or replacement.

[0033] The pushing assembly includes a cylinder 2 and a transmission member 5, which is the power source for moving the filter assembly along the slide rail 1. The cylinder 2 pushes or pulls the object connected to it through telescopic movement. In this structure, the cylinder 2 is fixed to the lower surface of one of the slide rails 1 to provide a driving force. The transmission member 5 is an intermediate component connecting the cylinder 2 and the filter assembly. It is sleeved on the piston rod of the cylinder 2 and transmits the movement of the cylinder 2 to the filter assembly. The connecting member 6 is a component used to fix the transmission member 5 to the side wall of the filter assembly. In the present utility model, the connecting member 6 is connected to the filter assembly by a threaded connection, and the fastening between the components is achieved by the spiral structure of the thread. In this structure, one end of the transmission member 5 is connected to the side wall of the filter assembly by a threaded connection. This connection method allows the connection to be tightened or loosened by rotating the connecting member 6, thereby achieving quick and reliable fixation.

[0034] With this design, when the cylinder 2 is in action, the transmission member 5 will move accordingly, and in turn drive the filter assembly to translate along the slide rail 1 through the threaded connection. The advantage of this structure is that it can achieve the automatic or semi-automatic movement of the filter assembly, improving the production efficiency and the convenience of equipment maintenance. At the same time, the reliability of the threaded connection ensures the stability and safety of the entire system during operation.

[0035] Further, a sensor is arranged between the pushing assembly and the slide rail 1, which is used to detect whether the filter box assembly is pushed or retracted to a preset position.

[0036] Specifically, the sensor monitors the position state of the filter box assembly. When the filter box assembly is pushed to a preset pushing position, the sensor detects and sends a signal to inform the control system that the filter box assembly has reached the specified position. Similarly, when the filter box assembly is retracted to a preset retracted position, the sensor also detects and sends a signal. In this embodiment, the sensor is provided with two, i.e. a first sensor 3 and a second sensor 4, please refer to Figure 2 and Figure 3 , which are schematic diagrams of the translation structure in two states.

[0037] In one possible embodiment of the present application, the sensor can be set as a limit switch, which will be closed or opened when the filter box assembly contacts the limit switch, thereby generating a signal.

[0038] Or if there is a mark on the filter box assembly that can block the light beam, the sensor can be set as a photoelectric sensor, which detects whether the light beam is blocked to confirm the position of the filter box assembly.

[0039] Or the sensor can be set as a magnetic induction sensor, which can detect the existence of a magnetic field to determine the position of the assembly by installing a magnet on the filter box assembly.

[0040] When the filter box assembly reaches the preset position, the control system receives the signal of the sensor and commands the pushing assembly to stop working. If the filter box assembly does not reach the expected position, the sensor can trigger an error signal, and the control system can handle the error accordingly. The sensor can also be used to indicate the current state of the system, such as whether the filter box assembly is in the working position.

[0041] Further, the cylinder 2 is a magnetic coupling cylinder 2.

[0042] Specifically, the magnetic coupling cylinder 2 utilizes the principle of magnetic coupling to transfer power through magnetic interaction, rather than traditional mechanical connection. This allows for no direct physical contact between the piston portion of the cylinder 2 and the output shaft. Due to the absence of mechanical contact, the magnetic coupling cylinder 2 has less wear and tear, requires less maintenance, and has a longer service life. At the same time, the magnetic coupling cylinder 2 can provide high-precision position control, which is very important for applications that require precise movement of the filter box assembly.

[0043] Further, the filter assembly includes a mounting box 9, a primary filter 10 and a manganese dioxide filter 8, the primary filter 10 and the manganese dioxide filter 8 are placed in the mounting box 9, and the manganese dioxide filter 8 is placed on the primary filter 10, and the mounting box cover 7 is also provided on the primary filter 10.

[0044] Further, a plurality of openings are provided on the mounting box cover 7 for the filtered gas to pass out after passing through the primary filter 10 and the manganese dioxide filter 8.

[0045] Specifically, the mounting box 9 is a container for containing and fixing the filter, usually made of solid material to ensure the stability of the structure. The design of the mounting box 9 should facilitate the installation and replacement of the filter. The primary filter 10 is the first layer of the filter assembly, mainly used to intercept larger particles such as dust, pollen, hair, etc. The primary filter 10 usually has a larger pore size and lower resistance, facilitating air flow. The manganese dioxide filter 8 is usually used to remove harmful gases, odors and fine particles in the air. The manganese dioxide filter 8 has good chemical adsorption performance and can effectively purify the air. The mounting box cover 7 is a component that covers the mounting box 9, used to seal the filter assembly to prevent unfiltered air from directly entering the downstream of the filter, while protecting the internal filter from external pollution.

[0046] The multiple openings on the mounting box cover 7 are designed to ensure that the filtered gas can pass out of the filter assembly smoothly after passing through the primary filter 10 and the manganese dioxide filter 8. These openings should be large enough to avoid unnecessary resistance to air flow, while also being small enough to prevent unfiltered air from passing directly through. The openings are usually evenly distributed on the mounting box cover 7 to ensure that the air can be evenly distributed outside the filter assembly after passing through the filter, which helps to improve the overall filtering efficiency and uniformity of air flow distribution. The position and shape of the openings may be specially designed to guide the air flow to follow a predetermined path, which can optimize the flow characteristics of the gas, reduce vortex and pressure drop, and improve energy efficiency.

[0047] Further, please refer to Figure 4The sliding assembly is arranged on the filter assembly, and comprises a mounting seat 13 and a limiting pulley 12.

[0048] The contact between the limiting pulley 12 and the inner wall of the sliding rail 1 ensures the stability of the filter assembly during movement, reduces friction and vibration, and improves the accuracy of operation. Through the design of the limiting pulley 12, the movement distance and position of the filter assembly can be accurately controlled, which is particularly important when maintaining and replacing the filter. The sliding assembly makes the movement of the filter assembly easier, reduces the work intensity of the operator, and improves the work efficiency. The limiting pulley 12 can prevent the filter assembly from falling off or being damaged due to external force during movement, thereby improving the safety of the system. The design of the sliding assembly facilitates the quick disassembly and reinstallation of the filter assembly, simplifying the maintenance process.

[0049] In order to stabilize, a gasket 11 is arranged between the limiting pulley 12 and the mounting seat 13, which limits and prevents abrasion.

[0050] Further, the sliding rail 1 is made of stainless steel.

[0051] In a second aspect, the utility model also provides an isolator, which comprises an isolator body and the decomposition filter translation structure as claimed in any one of the above, the body has a return air inlet; the pushing member in the decomposition filter translation structure can push the filter box assembly to be placed in the return air inlet, so as to decompose hydrogen peroxide gas in the isolator body.

[0052] Further, the hydrogen peroxide gas in the isolator body passes out of the filter box assembly in a top-down direction.

[0053] When it is necessary to process hydrogen peroxide gas, the air cylinder 2 in the pushing assembly is activated, and the filter box assembly is moved along the sliding rail 1 through the transmission member 5 and the connecting member 6 until the filter box assembly is completely placed in the return air inlet. Hydrogen peroxide gas is decomposed and purified by the primary filter 10 and the manganese dioxide filter 8. The primary filter 10 is responsible for removing larger particulate matter, while the manganese dioxide filter 8 is used to decompose hydrogen peroxide gas, which may be converted into water and oxygen through catalytic action. The purified gas then flows out of the opening on the mounting box cover 7 back into the environment in the isolator body, or is discharged to the external environment.

[0054] The above application of specific examples to the utility model is described, which is only used to help understand the utility model, and does not limit the utility model. For the skilled person in the technical field to which the utility model belongs, according to the idea of the utility model, a number of simple deductions, deformations or substitutions can be made.
