Description

Technical Field

[0001] The utility model relates to the field of compressed air dryer equipment, in particular to an air flow diffuser. Background Art

[0002] During the operation of the adsorption dryer, the adsorbent in the adsorption tower is subjected to frequent impacts of pressure, water vapor and heat for most of the time, and is easily mechanically broken. On the other hand, the rapid pressure reduction during frequent switching of the drying tower will also cause the adsorbent to move greatly in the tower and rub against each other and become powder. At this time, if the adsorbent is not replenished in time, a significant space will appear in the upper part of the adsorption tower. When compressed air enters the lower part of the adsorption tower, the adsorbent will be rapidly displaced in a short period of time under the impact of the airflow, causing the adsorbent to collide and rub against each other and hit the wall of the adsorption tower, which will easily cause the adsorbent to further become powdered and ineffective.

[0003] At present, the solution to the above problem is to set a level switch on the top side of the adsorption tower to monitor the adsorption bed sedimentation state and prompt the user to add adsorbent to prevent the adsorbent from continuous powdering due to bed sedimentation. However, this method is costly and cannot effectively monitor the adsorbent level in the middle and accurately feedback the corresponding level sedimentation information. Utility Model Content

[0004] The utility model aims to provide an airflow diffuser which can timely and accurately display the material level sedimentation information of the adsorbent.

[0005] In order to solve the above technical problems, the utility model provides an air flow diffuser, including a diffuser body, a base arranged on one side of the diffuser body, and an end cover arranged on the other side of the diffuser body. A pressure plate is provided on the side of the end cover away from the base, and a sliding rod is connected to one side of the pressure plate. The sliding rod can move relative to the end cover, a static contact is provided on the inner side of the end cover, and a moving contact matching the static contact is provided on one side of the sliding rod. When the moving contact contacts the static contact, material level settlement information is output.

[0006] Furthermore, an auxiliary elastic member is provided between the pressing plate and the end cover and is arranged around the circumference of the sliding rod.

[0007] Furthermore, a sealing ring is provided at the connection between the sliding rod and the end cover.

[0008] Furthermore, a fixing rod is connected between the end cover and the base.

[0009] Furthermore, a plurality of through-hole structures are provided on the pressing plate.

[0010] Furthermore, the moving contact and the slide bar are in movable cooperation.

[0011] Furthermore, the moving stroke of the moving contact relative to the sliding rod is greater than 5 cm.

[0012] Furthermore, the moving contact is in line contact with the static contact.

[0013] Furthermore, the sliding rod is a sliding variable resistor.

[0014] Furthermore, the diameter of the through hole structure is 1.5 mm-2.5 mm.

[0015] The beneficial effects of the utility model are:

[0016] 1. The pressure plate is pressed against the upper surface of the adsorbent. When the adsorbent level drops, the auxiliary elastic member and the pressure plate drop synchronously, so that after the adsorbent level drops to the warning position, the moving contact and the static contact contact and output the level settlement information to ensure that the user can know it accurately and timely.

[0017] 2. The moving contact can be moved relative to the slide bar, so that the user can adaptively adjust the distance between the moving contact and the static contact according to different material level settlement height requirements.

[0018] 3. The through-hole structure can ensure that the airflow can enter the diffuser body through the pressure plate position, thereby reducing the impact of the pressure plate on the airflow distribution. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0022] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0023] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0024] like Figure 1 The utility model provides an air flow diffuser, including a diffuser body 1, a base 2 arranged on one side of the diffuser body 1, and an end cover 3 arranged on the other side of the diffuser body 1. A pressure plate 4 is provided on the side of the end cover 3 away from the base 2, and a slide rod 5 is connected to one side of the pressure plate 4. The slide rod 5 can move relative to the end cover 3. A static contact 6 is provided on the inner side of the end cover 3, and a moving contact 7 matching the static contact 6 is provided on one side of the slide rod 5. When the moving contact 7 contacts the static contact 6, the material level settlement information is output.

[0025] Among them, the diffuser body is similar to the existing airflow diffuser, airflow distributor and other structures, allowing the airflow to enter the diffuser from the opening position at the end cover and diffuse the airflow through the metal mesh surrounding the outer periphery of the diffuser.

[0026] It is worth mentioning that when the moving contact contacts the static contact, a signal is output to the outside to remind the user that the adsorbent sedimentation position is low and the adsorbent needs to be replenished in time.

[0027] When installing the air diffuser of the present solution, the air diffuser is installed at the top air outlet of the adsorption tower to ensure that the compressed air flows toward the air diffuser after passing through the adsorbent inside the adsorption tower.

[0028] The adsorbent in this scheme can be activated alumina or molecular sieve.

[0029] Preferably, an auxiliary elastic member 8 is provided between the pressing plate 4 and the end cover 3 and is circumferentially arranged around the sliding rod 5 .

[0030] Specifically, when the adsorbent level is high, the pressure plate is squeezed by the adsorbent surface, so that the pressure plate is close to the end cover. When the adsorbent level decreases, the pressure plate drops with the level. At this time, the pressure plate is pushed down by the auxiliary elastic member, which can effectively ensure the stability of the descent of the pressure plate.

[0031] Wherein, the auxiliary elastic member adopts a damping spring.

[0032] Preferably, a sealing ring is provided at the connection between the sliding rod 5 and the end cover 3 to ensure relative sealing between the sliding rod and the end cover.

[0033] In one embodiment of the present solution, the sealing ring adopts an O-type structure.

[0034] Preferably, a fixing rod 9 is connected between the end cover 3 and the base 2 .

[0035] Specifically, the end cover, the base and the diffuser body are supported by fixing rods to ensure the stability of the overall structure of the airflow diffuser.

[0036] In one embodiment of the present solution, the fixing rod is a single-start screw rod equipped with a stop nut.

[0037] Preferably, a plurality of through-hole structures are provided on the pressing plate 4 so as to reduce the influence of the pressing plate on the airflow distribution.

[0038] In one embodiment of the present solution, the diameter of the through hole structure is 1.5 mm-2.5 mm.

[0039] It is worth mentioning that the diameter of the through-hole structure is slightly larger than the particle diameter of the adsorbent to avoid the adsorbent clogging the through-hole structure.

[0040] Preferably, the movable contact 7 and the slide rod 5 are in movable cooperation.

[0041] Specifically, the movable contact can be moved relative to the slide bar, so that the user can adaptively adjust the distance between the movable contact and the static contact according to different material level settlement height requirements.

[0042] Among them, the moving contact and the sliding rod can be matched in a manner that a sliding groove is opened on the side of the sliding rod along the height direction, and the moving contact is movably installed in the sliding groove. When the moving contact moves to a specified position relative to the sliding groove, the moving contact is fixed to the sliding groove through connecting parts such as threads.

[0043] In a preferred embodiment of the present solution, the moving stroke of the movable contact 7 relative to the sliding rod 5 is greater than 5 cm.

[0044] Preferably, the moving contact 7 is in line contact with the stationary contact 6 to ensure the stability of the signal output when the moving contact is in contact with the stationary contact.

[0045] Preferably, the slide bar 5 is a sliding variable resistor, so that when the slide bar moves relative to the end cover, its output resistance value changes synchronously with the distance between the pressure plate and the end cover, thereby displaying the material level information in real time.

[0046] The present utility model is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all those having the same or similar technical solutions as the present application fall within the protection scope of the present utility model.
