Description

Technical Field

[0001] This application relates to the technical field of cold dryers, and specifically discloses an exhaust device for a cold dryer. Background Art

[0002] A cold dryer is short for a refrigerated dryer. It adopts new technologies and belongs to the air source treatment components in the pneumatic system. Its working principle is to use the refrigerant to exchange heat with the compressed air and reduce the temperature of the compressed air to the dew point temperature in the range of 2 - 10°C.

[0003] Currently, the exhaust devices of most cold dryers are fan blade structures. The fan blade structure includes left and right fan blades and upper and lower fan blades. The upper and lower fan blades are driven as a whole by a motor to realize the up and down movement of the upper and lower fan blades. The left and right fan blades are externally placed outside the cold dryer and are manually moved left and right. Based on the cooperation of the up and down movement of the upper and lower fan blades and the left and right movement of the left and right fan blades, the exhaust direction of the cold dryer can be adjusted.

[0004] This mode is mature and stable, but there are still certain problems: Due to the use of the cold dryer, a large amount of dust will cover the blades of the upper and lower fan blades and the left and right fan blades. Although the left and right fan blades can be manually cleaned, there are still cleaning dead corners after being integrated with the cold dryer. Moreover, the upper and lower fan blades located deeper inside are more difficult to clean due to the influence of the structural position of the left and right fan blades. In view of this, the inventor proposes an exhaust device for a cold dryer. Utility Model Content

[0005] The purpose of the present utility model is to solve the problem that it is rather troublesome to clean the dust of the traditional exhaust device.

[0006] To achieve the above purpose, the present utility model provides the following basic solution:

[0007] An exhaust device for a cold dryer, including a cold dryer body, characterized in that: it further includes a plurality of card slots arranged on the exhaust end face of the cold dryer body and a quick-release exhaust component detachably connected to the card slots;

[0008] The quick-release exhaust component includes a frame body, a plurality of connecting rods arranged horizontally and evenly and detachably connected in the frame body, and swinging fan blades fixed on the connecting rods. The length of one side of the swinging fan blades exceeds the surface height of the frame body, and the height of the other side of the swinging fan blades is the same as the surface height of the other side of the frame body.

[0009] The principle and effect of this basic solution are as follows:

[0010] 1. Compared with the prior art, the structure of this device is simple and ingenious. The core of this device lies in quick disassembly. A quick-disassembly exhaust component is provided, which can be quickly separated from the main body of the refrigerant dryer and is screwless. When the quick-disassembly exhaust component is quickly separated from the main body of the refrigerant dryer, the electric drive fan blade components above and below inside the main body of the refrigerant dryer are directly exposed. And after the quick-disassembly exhaust component is disassembled, the swing fan blades are also directly exposed. The advantage of this design is that for cleaning, the electric drive fan blade components and the swing fan blades are independent of each other, making it convenient to clean the dust, and solving the problem that it is relatively troublesome to clean the dust of the traditional exhaust device.

[0011] 2. Compared with the prior art, this device is provided with a quick-disassembly exhaust component, and the installation and disassembly of the quick-disassembly exhaust component are very convenient and do not affect the normal use of the main body of the refrigerant dryer.

[0012] 3. Compared with the prior art, this device does not adopt the traditional structural design that can make the swing fan blades become the same plane after being closed, but adopts the design that the length of one side of the swing fan blade exceeds the surface height of the frame body, and the other side of the swing fan blade is at the same surface height as the other side of the frame body. The advantage of this design is that it is easier to clean the dead corners. The structural design of becoming the same plane has a cleaning blind area in the rotation dead corners. After adopting this device, all the main bodies of the swing fan blades are completely exposed, making it easier to clean the dust. And after the other side of the swing fan blade is at the same surface height as the other side of the frame body, in cooperation with the quick-disassembly exhaust component, since the other side of the swing fan blade is at the same surface height as the other side of the frame body, only overall wiping is needed for cleaning. Compared with the traditional structural design of becoming the same plane, cleaning the dust is simpler and easier.

[0013] 4. Compared with the prior art, a detachable connecting rod is adopted. The detachable connection of the connecting rod can realize the fine cleaning of the connecting rod and the swing fan blades, which is beneficial to better handle the dust on the swing fan blades. Furthermore, this device solves the problem that it is relatively troublesome to clean the dust of the traditional exhaust device.

[0014] Furthermore, the card slot adopts a right-angle slot, iron sheets are fixedly connected to the slot walls of the right-angle slot, a magnet block is fixedly connected to the position of the frame body corresponding to the right-angle slot, the magnet block adopts a right-angle block, and the magnet block is magnetically connected to the iron sheet.

[0015] Furthermore, symmetrically fixedly connected pull blocks are provided on the surface of the frame body.

[0016] Furthermore, angular surfaces are symmetrically arranged on the side of the swing fan blade that exceeds the surface height of the frame body.

[0017] Further, the connecting rod includes a rod body, an insertion rod fixedly connected to one end of the rod body, a cavity rod fixedly connected to the other end of the rod body, a spring disposed in the cavity rod, and a telescopic rod disposed at the free end of the spring. Grooves are formed in the inner walls of the frame body, and the telescopic rod and the insertion rod are inserted into the corresponding grooves. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, describe in detail the specific embodiments, structures, features, and effects of the present invention as follows.

[0023] The reference numerals in the accompanying drawings of the specification include: cold dryer body 1, quick-release exhaust assembly 2, frame body 201, magnet block 202, pull block 203, connecting rod 204, swing fan blade 205, insertion rod 206, cavity rod 207, spring 208, telescopic rod 209, and card slot 3.

[0024] Embodiments are as Figure 1 , Figure 2 and Figure 3 shown:

[0025] An exhaust device for a cold dryer includes a cold dryer body 1, and further includes a plurality of card slots 3 provided on the exhaust end face of the cold dryer body 1 and a quick-release exhaust assembly 2 detachably connected to the card slots 3;

[0026] The quick-release exhaust component 2 includes a frame body 201, a plurality of connecting rods 204 that are detachably connected inside the frame body 201 and arranged horizontally and evenly, and swinging fan blades 205 fixed on the connecting rods 204. The length of one side of the swinging fan blade 205 exceeds the surface height of the frame body 201, and the other side of the swinging fan blade 205 is at the same height as the other side surface of the frame body 201.

[0027] Specifically: The card slot 3 is a right-angle slot, and iron sheets are fixedly connected to the slot walls of the right-angle slot. A magnet block 202 is fixedly connected to the position of the frame body 201 corresponding to the right-angle slot. The magnet block 202 is a right-angle block, and the magnet block 202 is magnetically connected to the iron sheet. The magnetic connection is a fast quick-release structure and is screw-free, and the overall structure is highly concise. Pulling blocks 203 are symmetrically and fixedly connected to the surface of the frame body 201. The purpose of the pulling blocks 203 is to quickly help relevant personnel pull out the quick-release exhaust component 2, realize the separation of the quick-release exhaust component 2 from the cold dryer body 1, and is beneficial to subsequent cleaning steps.

[0028] Angular surfaces are symmetrically arranged on the side of the swinging fan blade 205 that exceeds the surface height of the frame body 201, which is convenient for the air flow to flow out along the angular surfaces. As Figure 3 shown, the connecting rod 204 includes a rod body, an insertion rod 206 fixedly connected to one end of the rod body, a cavity rod 207 fixedly connected to the other end of the rod body, a spring 208 arranged inside the cavity rod 207, and a telescopic rod 209 arranged at the free end of the spring 208. Grooves are opened on the inner walls of the frame body 201, and the telescopic rod 209 and the insertion rod 206 are inserted into the corresponding grooves.

[0029] Specifically: Utilize the compression characteristic of the spring 208 to change the length of the telescopic rod 209, so that the telescopic rod 209 and the insertion rod 206 are inserted into the corresponding grooves and realize the clamping connection between the connecting rod 204 and the grooves.

[0030] Specific implementation process:

[0031] In the first step, use the card block to quickly disassemble the quick-release exhaust component 2, so that the quick-release exhaust component 2 is separated from the cold dryer body 1. Since the quick-release exhaust component 2 is separated from the cold dryer body 1, the electric drive fan blade inside the cold dryer body 1 is directly exposed, and effective cleaning and dust removal can be carried out.

[0032] Second step, for the cleaning of the quick-release exhaust component 2, since the swinging fan blade 205 that swings manually is adopted, the swinging fan blade 205 can be directly swung, and there is no damage to the electric drive component. Moreover, the length of one side of the swinging fan blade 205 exceeds the surface height of the frame 201, and the other side of the swinging fan blade 205 is at the same surface height as the other side of the frame 201. Therefore, the cleaning of the swinging fan blade 205 becomes convenient. For the other side of the swinging fan blade 205, when wiping the frame 201, the other side of the swinging fan blade 205 can be cleaned incidentally.

[0033] Third step, if stubborn dust appears on the swinging fan blade 205, only by pressing down on the connecting rod 204 forcefully can the swinging fan blade 205 be separated from the frame 201, and then the refined dust removal and cleaning work on the swinging fan blade 205 can be carried out.

[0034] This device solves the problem that it is rather troublesome to clean the dust of the traditional exhaust device.

[0035] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
