Description

Technical Field

[0001] This utility model relates to the field of dryer technology, specifically to an automatic dehumidification device for a static chamber dryer. Background Technology

[0002] According to research, the static dryers currently on the domestic market are used to dry grains. During the grain drying process, the moisture in the grains evaporates into the machine. In order to remove the high-temperature and humid air from the dryer, the dehumidification method commonly used is for the dehumidification fan to work continuously.

[0003] In the actual use of a static grain dryer, humidity sensors are mainly used to detect the air humidity inside the dryer to measure the degree of grain drying. Therefore, using continuous dehumidification will affect the accuracy of detecting the degree of grain drying; at the same time, it will exhaust the hot air used for drying grain inside the dryer, and the exhaust high-temperature gas needs to be continuously replenished, resulting in a large amount of fuel waste. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the purpose of this invention is to provide an automatic dehumidification device for a static chamber dryer, solving the technical problem of reducing fuel waste while improving the detection effect of grain drying degree.

[0005] This utility model is achieved through the following technical solution:

[0006] An automatic dehumidification device for a static chamber dryer includes a controller, a humidity sensor, a dehumidifying fan, a mounting frame, a baffle, and a cylinder. The four corners of the mounting frame and the cylinder body are fixed to the dryer housing. The mounting frame has two through slots: a circular through slot and a receiving through slot. The circular through slot is aligned with an exhaust port on the dryer housing. The dehumidifying fan is bolted to mounting holes around the circular through slot. A through hole is provided on the side wall of the mounting frame, through which the telescopic end of the cylinder passes and connects to the mounting plate. The bracket is fastened to the edge of the baffle with bolts. A groove is formed on the middle of the wall of the circular through groove and the middle of the wall of the receiving through groove. A slot is formed between the circular through groove and the receiving through groove to connect them. The slot and the groove together form a sliding groove a, which allows the baffle to move horizontally on the sliding groove a. When the extension rod of the cylinder extends, it can push the baffle to completely cover the circular through groove. When the extension rod of the cylinder retracts, it can pull the baffle to completely withdraw from the circular through groove. The controller is electrically connected to the humidity sensor, the dehumidifier, and the cylinder.

[0007] Preferably, the mounting bracket is an elastic clip, and its connecting part has a hole for vertical installation with the telescopic end of the cylinder. After the elastic clip clamps the edge of the baffle, its clamping arm has a hole that corresponds to the hole on the edge of the baffle. Bolts are passed through the holes in sequence, and then the fastening nuts are tightened.

[0008] Preferably, the fastening bolt is a flange bolt, and the fastening nut is a flange nut.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This invention features an installation frame between the dryer's exhaust vent and the dehumidifying fan. The frame is divided into a circular channel and a receiving channel. The circular channel aligns with the exhaust vent, and a baffle slides within the receiving channel, extending onto the circular channel. A cylinder is connected to the side of the baffle, automatically controlling its movement in and out of the circular channel. When the high-temperature, high-humidity gas inside the dryer reaches a set value, the cylinder receives a signal and automatically pulls out the baffle in the circular channel, simultaneously opening the dehumidifying fan to expel the accumulated hot and humid air. Conversely, when the cylinder receives a signal, it automatically pushes the baffle in the receiving channel, simultaneously shutting off the dehumidifying fan. This cycle repeats until the grain drying process is complete, thus solving the technical problem of reducing fuel waste while improving the detection effect of grain drying degree.

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings. To solve the technical problem of reducing fuel waste while improving the detection effect of grain drying degree, such as... Figure 1-6 An automatic dehumidification device for a static chamber dryer was designed, including a controller, a humidity sensor, a dehumidifying fan, a mounting frame 1, a baffle 2, and a cylinder 3. The four corners of the mounting frame 1 and the cylinder body of the cylinder 3 are fixed to the dryer housing. Two through slots are provided inside the mounting frame 1: a circular through slot 101 and a receiving through slot 102. The circular through slot 101 is aligned with the exhaust port on the dryer housing. The dehumidifying fan is bolted to the mounting hole 1011 around the circular through slot 101. A through hole 103 is provided on the side wall of the mounting frame 1. The telescopic end of the cylinder 3 passes through the through hole 103 and connects to... There is a mounting bracket 4, which is fastened to the edge of the baffle 2 by bolts. A groove is formed on the middle of the wall of the circular through groove 101 and the middle of the wall of the receiving through groove 102. A slot is formed between the circular through groove 101 and the receiving through groove 102 to open them up. The slot and the groove together form a sliding groove a, which allows the baffle 2 to move horizontally on the sliding groove a. When the telescopic rod of the cylinder 3 extends, it can push the baffle 2 to completely cover the circular through groove 101. When the telescopic rod of the cylinder 3 retracts, it can pull the baffle 2 to completely withdraw from the circular through groove 101. The controller is electrically connected to the humidity sensor, the dehumidifier, and the cylinder 3. When the high-temperature, high-humidity gas inside the dryer reaches the set value, cylinder 3 receives a signal and automatically pulls out the baffle 2 located in the circular channel 101, and the exhaust fan simultaneously turns on to expel the accumulated hot and humid air. Conversely, when cylinder 3 receives a signal, it automatically pushes the baffle 2 located in the receiving channel 102 until it covers the circular channel 101, and the exhaust fan simultaneously turns off. This cycle repeats until the grain drying is complete, thus solving the technical problem of reducing fuel waste while improving the detection effect of grain drying degree.

[0021] It is worth mentioning that the aforementioned controller is equipped with a control system. For details of the specific technology, please refer to the published patent document with patent number 201621046440.1 and patent title "An Intelligent Control System for a High-Efficiency Dryer". This is prior art. Those skilled in the art can rely on the feedback data of the humidity sensor to control the movement of the cylinder's extension and retraction end, which will not be elaborated here.

[0022] Because the repeated extension and retraction of the cylinder 3 pushes the mounting bracket 4, it affects the stability of the connection between the mounting bracket 4 and the baffle 2. Therefore, if Figure 5 The mounting bracket 4 is set as an elastic clamp, and its connecting part 401 has a hole for vertical installation with the telescopic end of the cylinder 3. After the elastic clamp is used to clamp the edge of the baffle 2, the clamping arm 402 has a hole that corresponds to the hole on the edge of the baffle 2. Bolts are passed through the holes in sequence, and then the fastening nuts are tightened to strengthen the connection between the mounting bracket 4 and the baffle 2.

[0023] To facilitate quick installation and disassembly of the mounting bracket 4 and the baffle 2, such as Figure 6 The fastening bolts are flange bolts, and the fastening nuts are flange nuts.

[0024] The working principle of this utility model:

[0025] When the dehumidification device is turned off, the dehumidification fan is also off. At this time, as hot air continuously enters the dryer and moisture evaporates from the grain inside, high-temperature, high-humidity gas forms at the top of the dryer due to the continuous upward flow of hot air. This high-temperature, high-humidity gas not only heats and dries the grain at the top but also maintains stable humidity inside the dryer to a certain extent, reducing grain breakage and improving the quality of the dried grain. Figure 1 When the high-temperature, high-humidity gas inside the dryer reaches the set value, the dehumidification device receives a signal and automatically opens, and the dehumidification fan also turns on simultaneously to expel the accumulated hot and humid air. When the internal high-temperature, high-humidity gas is detected to have reached the preset value, the dehumidification device receives a signal and automatically closes. This cycle repeats until the grain drying is complete. The automatic dehumidification device solves the problem of current static chamber dryers on the market, which continuously expel large amounts of high-temperature gas while expelling moisture, requiring continuous replenishment of the expelled high-temperature gas and resulting in significant fuel waste.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
