Description

Technical Field

[0001] This utility model belongs to the field of drying equipment technology, specifically relating to a blower-regenerated adsorption dryer. Background Technology

[0002] A dryer is a device used to remove moisture from materials and is widely used in various industries such as chemical, food, pharmaceutical, and agriculture. Based on different working principles, dryers can be classified into several types. According to operating pressure, dryers are divided into atmospheric pressure dryers and vacuum dryers. Based on operating pressure, they can be divided into atmospheric pressure dryers and vacuum dryers.

[0003] Authorized publication number "CN220257629U" discloses an adsorption-type air dryer, including a support frame and a buffer mechanism. Two drying towers are symmetrically and fixedly connected to the upper end face of the support frame. An air inlet pipe is fixedly connected to the lower end face of the two drying towers, and an air outlet pipe is fixedly connected to the upper end face of the two drying towers. A processing box is fixedly connected to the upper end of the air outlet pipe. An activated carbon filter is slidably connected to the inner wall of the processing box. A fixing block is fixedly connected to the right side of the processing box, and a groove is formed on the right side of the fixing block. In operation, air enters through the air inlet pipe, is dried by the drying towers, and then discharged into the processing box through the air outlet pipe. The activated carbon filter adsorbs odors, thus preventing the release of air with unpleasant odors into the air and avoiding environmental pollution.

[0004] The aforementioned new activated carbon filter can adsorb odors, thereby preventing air with unpleasant smells from being released into the air and avoiding environmental pollution. However, the aforementioned new airflow filter will affect the airflow speed. When the device needs to quickly dry the environment, the airflow speed of the device will be accelerated, and the airflow speed affected by the filter will affect the air drying efficiency in emergency situations. Utility Model Content

[0005] The purpose of this invention is to provide a blower-type regenerative adsorption dryer, which aims to solve the problem in the prior art where, when the device needs to quickly dry the environment, the increased airflow caused by the filter affects the airflow speed and thus reduces the drying efficiency in emergency situations.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A blower-type regeneration adsorption dryer includes:

[0008] Adsorption dryer body;

[0009] A ventilation duct is fixedly connected to the upper end of the adsorption dryer body;

[0010] The primary purification assembly comprises two sets. Each set includes a support ring, a spring sleeve, a sliding groove, a closing ring, a purification cylinder, a sliding rod, and a return spring. Two spring sleeves, sliding grooves, sliding rods, and return springs are provided. The support ring is fixedly connected to the inner circumference of the ventilation duct. Both spring sleeves are fixedly connected to one side of the support ring. Two sliding grooves are respectively opened on one side of the two spring sleeves. Two sliding rods are slidably connected within the two sliding grooves. Two return springs are respectively fixedly connected to one side of the inner wall of the two spring sleeves and one side of the two sliding rods. The closing ring is fixedly connected to one side of the two sliding rods. The purification cylinder is fixedly connected to one side of the closing ring.

[0011] As a preferred embodiment of this utility model, the purification cylinder is provided with multiple purification channels, and all of the multiple purification channels are spiral-shaped.

[0012] In a preferred embodiment of this utility model, an air inlet pipe is fixedly connected to the upper end of the ventilation pipe, and a fan is fixedly connected inside the air inlet pipe.

[0013] As a preferred embodiment of this utility model, the ventilation pipe is provided with two thickened pipes, and the two thickened pipes are respectively matched with the positions of the two purification cylinders.

[0014] As a preferred embodiment of this utility model, the adsorbent in the adsorption dryer is active alumina with high environmental resistance, and the gas flow rate is controlled at 40-45 Ft / min.

[0015] As a preferred embodiment of this utility model, the height of the adsorption dryer body is two meters, and the top and bottom of the adsorption dryer body are equipped with airflow distribution devices.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In this solution, when the adsorption dryer needs to increase its drying power, the pressure difference on both sides of the closed ring will create a thrust on one side of the closed ring, causing the return spring to be compressed and contracted. This opens the closure between the closed ring and the support ring, allowing air to directly enter the adsorption dryer through the gap between the support ring and the closed ring, thereby improving air circulation efficiency and preventing the filtration system of the purification cartridge from affecting the air drying efficiency in emergency situations.

[0018] 2. In this solution, through this device, when air enters the adsorption dryer through the purification channel, impurities rotate within the spiral purification channel and come into full contact with the inner wall of the purification channel. The impurities are adsorbed onto the inner wall of the purification channel, thereby improving the air purification efficiency. Attached Figure Description

[0025] 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.

[0026] Example

[0027] Please see Figure 1-Figure 4 The present invention provides the following technical solution:

[0028] A blower-type regeneration adsorption dryer includes:

[0029] Adsorption dryer body 1;

[0030] Ventilation pipe 2 is fixedly connected to the upper end of adsorption dryer body 1;

[0031] The primary purification component consists of two sets. Each set includes a support ring 3, a spring sleeve 4, a sliding groove 5, a closing ring 6, a purification cylinder 7, a sliding rod 8, and a return spring 9. Two spring sleeves 4, sliding grooves 5, sliding rods 8, and return springs 9 are provided. The support ring 3 is fixedly connected to the inner circumference of the ventilation duct 2. Both spring sleeves 4 are fixedly connected to one side of the support ring 3. Two sliding grooves 5 are respectively opened on one side of the two spring sleeves 4. Two sliding rods 8 are slidably connected within the two sliding grooves 5. Two return springs 9 are respectively fixedly connected to one side of the inner wall of the two spring sleeves 4 and one side of the two sliding rods 8. The closing ring 6 is fixedly connected to one side of the two sliding rods 8. The purification cylinder 7 is fixedly connected to one side of the closing ring 6.

[0032] In a specific embodiment of this utility model, the adsorption process of this device is the same as that of a conventional regeneration dryer, proceeding from bottom to top. The adsorption dryer body 1 is equipped with two heating and cooling towers. The ventilation pipe 2, which connects the two cooling towers, contains two sets of primary purification components for preliminary purification of the air at the dryer's air inlet. The two sets of primary purification components are located at the air inlet of the two purification towers. The support ring 3 supports the closing ring 6. The return force of the return spring 9 pushes the sliding rod 8 to close the closing ring 6 with the support ring 3. At this time, if air wants to flow from the ventilation pipe 2, it must flow from the purification cylinder 7 into the purification tower of the adsorption dryer body 1. Impurities in the air flowing from the purification cylinder 7 are purified. The adsorption of air by the adsorption cylinder 7 allows the adsorption dryer 1 to purify airborne particles and small airborne matter while drying the air, thus improving air purification efficiency. When the adsorption dryer 1 needs to increase its drying power, the wind speed in the ventilation pipe 2 increases. If the wind speed is high and the airflow speed in the channel of the purification cylinder 7 is slow, the pressure difference on both sides of the sealing ring 6 will create a thrust on one side of the sealing ring 6, which will push the return spring 9 to be squeezed and contracted, thereby opening the closed joint between the sealing ring 6 and the support ring 3. At this time, air can directly enter the adsorption dryer 1 from the gap between the support ring 3 and the sealing ring 6, thereby improving airflow efficiency and preventing the filtration system of the purification cylinder 7 from affecting the air drying efficiency in emergency situations.

[0033] Please refer to the details. Figure 1-Figure 4 The purification cylinder 7 has multiple purification channels 10, all of which are spiral-shaped.

[0034] In this embodiment, the purification channel 10 is located on one side of the purification cylinder 7, and its inner wall is made of activated carbon material. When air enters the adsorption dryer 1 through the purification channel 10, impurities rotate in the spiral purification channel 10 and come into full contact with the inner wall of the purification channel 10, and are adsorbed on the inner wall of the purification channel 10, thereby improving the air purification efficiency.

[0035] Please refer to the details. Figure 1-Figure 4 The upper end of the ventilation pipe 2 is fixedly connected to the air inlet pipe 12, and the air inlet pipe 12 is fixedly connected to the fan 13.

[0036] In this embodiment: the air inlet pipe 12 is located in the middle of the ventilation pipe 2 for air intake, and the fan 13 is located at the upper opening of the air inlet pipe 12. When the fan 13 is running normally to dry the air, the air passes through the channel of the purification channel 10 to filter impurities. When high-power air drying is required, the fan 13 operates under load to improve the air intake efficiency in the adsorption dryer body 1.

[0037] Please refer to the details. Figure 1-Figure 4 Two thickened pipes 11 are provided inside the ventilation pipe 2, and the two thickened pipes 11 are respectively matched with the positions of the two purification cylinders 7.

[0038] In this embodiment: the thickened pipe 11 is installed in the ventilation pipe 2 as a thickened channel. When the closing ring 6 and the support ring 3 are no longer closed, the air in the ventilation pipe 2 flows into the adsorption dryer body 1 from the thickened end of the thickened pipe 11 to improve the air circulation speed.

[0039] Please refer to the details. Figure 1-Figure 4 The adsorbent in the body 1 of the adsorption dryer is made of activated alumina with high environmental resistance, and the gas flow rate is controlled at 40-45 Ft / min.

[0040] In this embodiment: the activated alumina dryer can quickly remove moisture from the material, improve drying efficiency, and complete the drying process at a lower temperature, effectively protecting the physical and chemical properties of activated alumina and preventing activity loss due to high temperature. The gas flow rate is 40-45 Ft / min under normal conditions, which avoids tunneling effect, prevents boiling wear in the desiccant tower, and reduces pressure loss due to resistance flowing through the tower.

[0041] Please refer to the details. Figure 1-Figure 4 The height of the adsorption dryer body 1 is two meters, and the top and bottom of the adsorption dryer body 1 are equipped with airflow distribution devices.

[0042] In this embodiment: the height of the straight section of the tower is guaranteed to ensure that the desiccant is in full contact with the air medium. The top and bottom of the tower are equipped with airflow distribution devices to ensure that the airflow is evenly distributed across the cross-section of the tower. This is especially effective for equipment with a large tower diameter, preventing the tunneling phenomenon of airflow.

[0043] It should be noted that the adsorption dryer 1 used in this device is existing technology and will not be described in detail here.

[0044] The working principle and usage process of this utility model: The adsorption process of this device is the same as that of a conventional regeneration dryer, proceeding from bottom to top. The adsorption dryer body 1 is equipped with two heating and cooling towers. The ventilation pipe 2, which connects the two cooling towers, contains two sets of primary purification components for preliminary purification of the air at the dryer's air inlet. The two sets of primary purification components are located at the air inlet of the two purification towers. The support ring 3 supports the closing ring 6. The return force of the return spring 9 pushes the sliding rod 8 to close the closing ring 6 with the support ring 3. At this time, if air wants to flow through the ventilation pipe 2, it must flow into the purification tower of the adsorption dryer body 1 through the purification cylinder 7. The air flowing through the purification cylinder 7 contains impurities. Adsorbed by the purification cylinder 7, the adsorption dryer 1 purifies airborne particles and small airborne matter while drying the air, improving air purification efficiency. When the adsorption dryer 1 needs to increase its drying power, the wind speed in the ventilation pipe 2 increases. If the wind speed is high and the airflow speed in the channel of the purification cylinder 7 is slow, the pressure difference on both sides of the sealing ring 6 will create a thrust on one side of the sealing ring 6, and push the return spring 9 to be squeezed and contracted, thereby opening the closed joint between the sealing ring 6 and the support ring 3. At this time, air can directly enter the adsorption dryer 1 from the gap between the support ring 3 and the sealing ring 6, thereby improving airflow efficiency and preventing the filtration system of the purification cylinder 7 from affecting the air drying efficiency in emergency situations.

[0045] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
