Description

Technical Field

[0001] This utility model relates to a dryer, specifically a plate heat exchanger dryer, and belongs to the field of dryer technology. Background Technology

[0002] Plate heat exchanger dryers, also known as plate-fin refrigerated dryers, work on the principle of refrigeration dehumidification. The plate heat exchanger dryer uses an internal heat exchanger to efficiently exchange heat between the refrigerant and the air, which significantly lowers the air temperature. As a result, the moisture in the air condenses into water droplets, which are then completely separated from the air by a separator, thus achieving the dehydration and drying of the air.

[0003] Over time, the heat exchangers in plate heat exchanger refrigerated dryers become contaminated with dust, oil, and other pollutants from the air. These contaminants adhere to the surface of the heat exchangers, causing scaling on the heat exchange plates, severely hindering heat transfer and reducing heat exchange efficiency. This not only affects the cooling effect of the refrigerated dryer but also increases energy consumption and even impacts the overall performance of the dryer. Furthermore, dust can enter critical components such as the compressor through the air inlet, causing wear and blockage to the compressor, affecting its lifespan and performance. Dust entering the dryer's interior also pollutes the dried air, affecting air quality. To address these issues, we propose a plate heat exchanger dryer. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model discloses a plate heat exchanger dryer, such as... Figure 1-5As shown, the device includes a housing 1, a heat exchanger 2 is installed inside the housing 1, a fan 4 is fixedly installed on the side wall of the housing 1, and a dustproof filter mechanism 3 is provided between the heat exchanger 2 and the fan 4. The dustproof filter mechanism 3 includes a filter plate 301, an L-shaped fastener 302, a fixing bolt 303, a wedge block 304, a pressure plate 305, and a spring 306.

[0020] The filter plate 301 is slidably connected inside the housing 1. The L-shaped fastener 302 is fixedly connected to the end of the filter plate 301. The fixing bolt 303 is rotatably connected to the top of the L-shaped fastener 302. The wedge block 304 is movably engaged with the bottom of the filter plate 301. The pressure plate 305 is fixedly connected to the bottom of the wedge block 304. The end of the spring 306 is fixedly connected to the bottom of the pressure plate 305. The wedge block 304 is fixedly connected to the pressure plate 305. The pressure plate 305 is fixedly connected to the spring 306. When the pressure plate 305 is pressed down, the wedge block 304 moves down synchronously, and the spring 306 tightens. When the pressure plate 305 is released, under the reaction action of the spring 306, the pressure plate 305 and the wedge block 304 move upward synchronously, realizing the locking and unlocking of the end of the filter plate 301, which facilitates the replacement of the filter plate 301.

[0021] See attached document Figure 4 As shown, an upper fixing block 307 is fixedly installed on the top of the inner side of the housing 1, and a lower fixing block 308 is fixedly installed on the bottom of the inner side of the housing 1. The bottom of the fixing bolt 303 abuts against the bottom of the upper fixing block 307. The other end of the spring 306 is fixedly connected to the lower fixing block 308. An L-shaped fixing piece 302 is fixedly installed on the end of the filter plate 301. The fixing bolt 303 is rotated and tightened at the end of the L-shaped fixing piece 302, so that the position of the filter plate 301 is fixed. A hole is opened at the bottom of the filter plate 301. When the filter plate 301 is fully pushed into the housing 1, the wedge block 304 will directly jam into the interior of the filter plate 301 under the reaction force of the spring 306. With the combined use of the wedge block 304 and the fixing bolt 303, the position of the filter plate 301 can be fixed, ensuring that the filter plate 301 will not shift its position during use and affect the normal use of the device.

[0022] See attached document Figure 4 As shown, guide grooves 309 are provided at the bottom of the upper fixing block 307 and the top of the lower fixing block 308. The filter plate 301 is slidably connected inside the guide grooves 309. The guide grooves 309 inside the upper fixing block 307 and the lower fixing block 308 are used to guide the movement of the filter plate 301, so that the filter plate 301 can be quickly positioned and the filter plate 301 can be quickly replaced, which greatly shortens the time required to replace the filter plate and does not affect the normal use of the device.

[0023] See attached document Figure 5 As shown, a sliding groove 311 is provided inside the lower fixing block 308.

[0024] See attached document Figure 5 As shown, a slider 310 is fixedly connected to the end of the pressure plate 305. The slider 310 is slidably connected inside the slide groove 311. The slider 310 at the end of the pressure plate 305 slides inside the slide groove 311. The slider 310 provides guidance for the movement of the pressure plate 305, so that the pressure plate 305 will not sway left and right when it moves, thus affecting the normal use of the pressure plate 305.

[0025] Working principle:

[0026] This type of plate heat exchanger dryer works by having the fan 4 draw air into the casing 1 during startup. The refrigerant circulates within the heat exchanger 2 through pipes, lowering the temperature of the guide plates. The drawn air enters the heat exchanger 2, where its heat is absorbed by the refrigerant, further reducing its temperature. Simultaneously, moisture is separated by the separator. The dried air is then discharged through an exhaust port on the other side of the casing 1. When the dust filter 3 inside the casing 1 is in use, the fan 4 draws the air to be processed into the casing 1, blowing it into the filter plate 301. Dust and other impurities carried by the air are adsorbed by the filter plate 301, and the purified air enters the heat exchanger 2. When the filter plate 301 needs to be replaced, the fan 4 grasps the back of the casing 1... Turn the handle over to open the protective cover, unscrew the fixing bolt 303 at the end of the L-shaped fastener 302, press the pressure plate 305 down to drive the wedge block 304 out of the filter plate 301, grab the filter plate 301 and take it out, align the end of the new filter plate 301 with the guide groove 309 inside the upper fixing block 307 and the lower fixing block 308 and insert it. The wedge block 304 at the end of the lower fixing block 308, with its arc surface abutting against the filter plate 301, is pushed into the lower fixing block 308, and the filter plate 301 is completely pushed into the housing 1. The wedge block 304 will automatically push into the hole at the bottom of the filter plate 301 under the reaction force of the spring 306. Tighten the fixing bolt 303, close the protective cover, and the replacement of the filter plate 301 is completed.

[0027] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
