Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic conveyors, in particular to a pressurized pneumatic conveyor. Background Art

[0002] Pneumatic conveyors are increasingly widely used in the transportation of various powders due to their advantages such as low loss and low energy consumption. A spiral pneumatic conveyor described in the patent with patent announcement number CN220055511U improves the material conveying efficiency by adding spiral shaft rotation, and at the same time adds a filter and a scraper device for cleaning the filter to the rear side of the Roots blower, thereby filtering the dust generated when the Roots blower generates airflow. However, if the scraper cleans the filter for a long time, dust will accumulate on the scraper itself, thereby affecting the working efficiency of the scraper. At the same time, the device is not designed with a booster component, which will affect the effect of pneumatic conveying and cause the conveyed items to accumulate and stay in the pipeline. A scraper that can be easily disassembled is now designed to clean the filter, and a booster component is also designed to pressurize the airflow, thereby increasing the effect of pneumatic conveying and preventing the conveyed items from accumulating in the pipeline.

[0003] Based on this, a pressurized pneumatic conveyor is now provided to eliminate the disadvantages of the existing devices. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0022] In one embodiment, Figure 1-Figure 3 As shown, a pressurized pneumatic conveyor includes a feed box 100, a storage box 101, a box cover 102, a feed pipe 103, a discharge pipe 104, an air inlet pipe 105, a motor 106 and a Roots blower 107. The top of the feed box 100 is provided with a box cover 102, the bottom of the feed box 100 is provided with a storage box 101, the bottom of the storage box 101 is provided with a feed pipe 103, the right side of the feed pipe 103 is connected to the discharge pipe 104, the Roots blower 107 is provided on the left side of the feed pipe 103, the air inlet pipe 105 is divided into a left air inlet pipe and a right air inlet pipe, the left side of the Roots blower 107 is connected to the left air inlet pipe, the Roots blower 107 is fixedly connected to the output end of the motor 106, the left air inlet pipe of the Roots blower 107 is further provided with a cleaning component 200, and the right side of the Roots blower 107 is provided with a boosting chamber 300;

[0023] During use, the box cover 102 is opened, and the articles to be transported by the pneumatic conveying device are poured into the feed box 100. The articles pass through the feed box 100 to the storage box 101, and then enter the delivery pipe 103 through the circular hole at the bottom end of the storage box 101. At this time, the motor 106 is started to make the Roots blower 107 start working. The Roots blower 107 draws air from the air inlet pipe 105 and then supplies air into the delivery pipe 103. Under the action of the air flow, the articles move forward in the delivery pipe 103, so that the articles are transported to the discharge pipe 104.

[0024] In one embodiment, Figure 2-Figure 3As shown, the cleaning assembly 200 includes an outer box 201, an ash collecting frame 202, a fixed shaft 203, a rotating shaft 204, a scraper 205, a sponge brush 206, a filter 207 and filter holes 208. The outer box 201 is connected to the left air inlet pipe, and the right air inlet pipe penetrates the outer box 201. The ash collecting frame 202 is arranged at the bottom end of the outer box 201, the fixed shaft 203 is arranged in the middle of the ash collecting frame 202, the rotating shaft 204 is arranged on the fixed shaft 203, and the rotating shaft 204 is provided with a scraper 205. The filter 207 is arranged on the left side of the right air inlet pipe, and the filter 207 is evenly provided with a plurality of filter holes 208.

[0025] When in use, the airflow sucked in by the Roots blower 107 through the air inlet pipe 105 passes through the cleaning component 200, and the airflow is filtered through the filter screen 207, so that the dust and debris in the airflow are retained on the filter screen 207. At the same time, when the airflow enters the outer box 201, it blows the scraper 205, so that the scraper 205 rotates on the filter screen 207, cleaning the dust and debris left on the filter screen 207 and the filter holes 208, so that the dust and debris fall into the ash collection frame 202. After the work is completed, the ash collection frame 202 can be removed from the outer box 201 to clean the dust and impurities in the ash collection frame 202 and replace the sponge brush 206 on the scraper 205. The fixed shaft 203 fixes the scraper 205 and the rotating shaft 204 in the ash collection frame 202, so that the scraper 205 can be dragged out together with the ash collection frame 202, thereby achieving the effect of cleaning the scraper 205 and reducing the impact of the scraper 205's own dust accumulation on the work efficiency slowdown.

[0026] In one embodiment, Figure 1-Figure 2 As shown, the boost chamber 300 is provided between the Roots blower 107 and the feed pipe 103. The air inlet on the left side of the boost chamber 300 is the same size as the air inlet pipe 105, and the air inlet on the right side of the boost chamber 300 is the same size as the feed pipe 103.

[0027] When in use, the airflow supplied by the Roots blower 107 to the conveying pipe 103 will first pass through the boosting chamber 300, so that the airflow is pressurized and then enters the conveying pipe 103, thereby improving the effect of pneumatic transportation and effectively reducing the impact of items staying in the conveying pipe 103 due to insufficient airflow.

[0028] In one embodiment, Figure 1-Figure 2 As shown, the diameter of the air inlet pipe 105 is larger than the diameter of the material delivery pipe 103;

[0029] When in use, the diameter of the air inlet pipe 105 is larger than the diameter of the material delivery pipe 103 , so that the air inlet of the pressurizing chamber 300 is larger than the air outlet, so that the air flow can be pressurized through the pressurizing chamber 300 .

[0030] In one embodiment, Figure 2As shown, a sliding door is provided on the front of the outer box 201 corresponding to the position of the dust collecting frame 202 , the top of the dust collecting frame 202 is flush with the bottom of the right air inlet pipe, and the top of the sliding door is flush with the top of the cleaning component 200 .

[0031] When in use, the dust collecting frame 202 can better collect the dust filtered by the filter 207. At the same time, the top of the sliding door is flush with the top of the cleaning component 200, so that when the dust collecting frame 202 is pulled out, the scraper 205 can also be pulled out together with the dust collecting frame 202, so that the dust on the scraper 205 can be cleaned and the sponge brush 206 on the scraper 205 can be replaced.

[0032] In one embodiment, Figure 3 As shown, the scraper 205 is provided with four pieces, namely, upper, lower, left and right pieces. Each of the four scrapers 205 is provided with a sponge brush 206. The four scrapers 205 are all made of plastic plates.

[0033] During use, the scraper 205 made of plastic material can better drive the rotating shaft 204 to rotate under the action of airflow. At the same time, the sponge brush 206 set on the scraper 205 can more effectively clean the dust and impurities remaining on the filter 207 and the filter hole 208, so that the filter 207 can be better cleaned and the service life of the filter 207 is improved.

[0034] In one embodiment, Figure 1-Figure 2 As shown, a circular opening is provided at the connection portion between the bottom end of the storage box 101 and the feed pipe 103, and the feed box 100 has a trapezoidal shape with a larger top and a smaller bottom.

[0035] When in use, the circular opening at the bottom of the storage box 101 is used for materials to enter the conveying pipe 103 from the storage box 101. At the same time, the trapezoidal shape of the feed box 100 with a larger top and a smaller bottom can make feeding the feed box 100 more convenient.

[0036] In one embodiment, Figure 2 As shown, the box cover 102 is provided with a rubber ring;

[0037] During use, the rubber ring on the box cover 102 can improve the sealing performance of the airflow conveying device, thereby preventing the entry of water vapor and the reduction of the conveying efficiency of the conveying pipe 103.

[0038] The working principle of the present invention is as follows: when in use, the box cover 102 on the feed box 100 is taken out, and the articles to be transported by the pneumatic conveying device are poured into the feed box 100. The articles will pass through the feed box 100 into the storage box 101, and then enter the delivery pipe 103 through the round hole at the bottom of the storage box 101. At the same time, the switch on the motor 106 is pressed to turn on the motor 106, so that the Roots blower 107 starts to work, and the Roots blower 107 draws air through the air inlet pipe 105. The airflow enters the outer box 201 through the left air inlet pipe, and then passes through the filter holes 208 on the filter screen 207. The dust and impurities in the airflow will be filtered onto the filter screen 207. At the same time, when the airflow passes through the scraper 205, the scraper 205 will start to rotate on the filter screen 207, so that the sponge brush 206 on the scraper 205 will clean the dust and impurities on the filter screen 207 and the filter holes 208, so that the dust and impurities on the filter screen 207 and the filter holes 208 are removed. Dust and impurities fall into the dust collecting frame 202 below. After the work is completed, you can open the sliding door and then pull the dust collecting frame 202 out of the outer box, and then clean the dust and impurities in the dust collecting frame 202. At the same time, you can clean the dust on the scraper 205 and replace the sponge brush 206, so as to extend the service life of the device and improve the use efficiency of the device. The air flow will enter the Roots blower 107 from the right air inlet pipe through the filter, and then enter the boost chamber 300. After passing through the boost chamber 300, the air flow will be pressurized and enter the feed pipe 103 to transport the items, and the items will be transported to the discharge pipe 104. The pressurized air flow will make the transportation of items more efficient, effectively reducing the items staying in the feed pipe 103 due to insufficient airflow, thereby reducing the efficiency of item transportation. After the item transportation is completed, you can press the switch again to turn off the motor 106 to stop the Roots blower 107.

[0039] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
