[0029] like Figure 1As shown, this embodiment provides a suction device, which includes a silo 1, an air suction mechanism 2, a filter mechanism 3, a back-blowing mechanism 4 and a discharge mechanism 5. A accommodating chamber 11 is provided inside the silo 1, a discharge port 12 is provided on the silo 1, the accommodating chamber 11 is connected to the outside through the discharge port 12, a suction pipe 13 connected to the accommodating chamber 11 is provided at one end of the silo 1, and the other end is connected to the output end of the air suction mechanism 2, the filter mechanism 3 is arranged between the suction pipe 13 and the air suction mechanism 2, the back-blowing mechanism 4 is used to clean the filter mechanism 3, and the discharge mechanism 5 includes a discharge driver 51 and a discharge door 52, and the discharge driver 51 can drive the discharge door 52 to move to open or close the discharge port 12.

[0030] In this embodiment, a receiving chamber 11 is provided inside the silo 1 for receiving materials. A discharge port 12 is provided on the silo 1, and the receiving chamber 11 is connected to the outside through the discharge port 12, so that the materials in the receiving chamber 11 can be discharged through the discharge port 12. A suction pipe 13 connected to the receiving chamber 11 is provided at one end of the silo 1, and the other end is connected to the output end of the exhaust mechanism 2. Through the operation of the exhaust mechanism 2, negative pressure can be generated inside the silo 1, so that the materials are sucked from the outside into the receiving chamber 11 through the suction pipe 13, thereby improving the working efficiency and preventing the materials from being scattered and causing dust storms. The filtering mechanism 3 is arranged between the suction pipe 13 and the exhaust mechanism 2, so that the materials are filtered by the filtering mechanism 3 and retained in the receiving chamber 11, so as to prevent the materials from entering the exhaust mechanism 2 and being damaged. The back-blowing mechanism 4 is used to clean the filter mechanism 3. The reverse airflow generated by the back-blowing mechanism 4 can blow off the material accumulated on the filter mechanism 3, so that the material can be discharged through the discharge port 12, which not only ensures the normal operation of the filter mechanism 3, but also improves the material transportation efficiency and quality. The discharge mechanism 5 includes a discharge driver 51 and a discharge door 52. The discharge driver 51 can drive the discharge door 52 to move to open or close the discharge port 12, and can accurately control the discharge of the material. Through the above-mentioned settings, the suction device of this embodiment can efficiently and conveniently realize the suction and transportation of materials, and the transportation effect is better.

[0031] Specifically, Figure 1 As shown, the silo 1 is provided with an openable and closable maintenance port 14 , and the accommodating chamber 11 is connected to the outside through the maintenance port 14 , so that the operator can conveniently clean and maintain the inside of the silo 1 .

[0032] More specifically, if Figure 1As shown, the suction device also includes a cover body 6, which can be set on the maintenance port 14. When the operator needs to maintain or repair the silo 1, he only needs to open the cover body 6, which is easier to operate. A sealing member is sandwiched between the cover body 6 and the maintenance port 14, ensuring that the cover body 6 can form a good seal with the silo 1 when the maintenance port 14 is closed, effectively preventing the entry of dust, moisture or other impurities. In addition, the sealing member can be a rubber ring or a rubber strip to ensure the sealing of the accommodating chamber 11.

[0033] Specifically, Figure 1 As shown, the air extraction mechanism 2 includes a fan 21 and an air extraction pipe 22. The output end of the fan 21 is connected to the accommodating chamber 11 through the air extraction pipe 22. The negative pressure generated by the fan 21 can be transmitted to the accommodating chamber 11 through the air extraction pipe 22, thereby forming a strong suction force inside the silo 1, thereby ensuring that the material can be quickly and effectively sucked into the silo 1 through the feed pipe, thereby improving the suction efficiency. In addition, those skilled in the art are aware of the specific working principle of the fan 21, which will not be repeated here.

[0034] Specifically, Figure 1 As shown, the filter mechanism 3 includes a support frame 31 and a filter element 32. The support frame 31 is connected to the accommodating chamber 11 and serves as a carrier for installing the filter element 32. The filter element 32 is arranged on the support frame 31 to ensure that the filter element 32 can operate stably in the accommodating chamber 11. The filter element 32 can separate the accommodating chamber 11 into a material chamber 111 and an air chamber 112. The material chamber 111 is used to temporarily accommodate the material sucked by the device, while the air chamber 112 is used to accommodate flowing air to ensure the normal operation of the suction mechanism 2. Through the above arrangement, the filter element 32 can intercept the material so that the material can be discharged and transported through the discharge port 12 in time, and can also prevent the material from entering the suction mechanism 2 to cause wear and corrosion to the internal parts, thereby extending the service life of the suction mechanism 2.

[0035] More specifically, if Figure 1 As shown, the support frame 31 includes a plurality of partitions 311, and the plurality of partitions 311 are arranged at intervals from the suction pipe 13 to the air suction mechanism 2, and a material placement chamber 111 is formed between two adjacent partitions 311, and an air storage chamber 112 is formed between the air suction mechanism 2 and its adjacent partition 311, so that after the material enters the storage chamber 11, it will be separated in the material placement chamber 111, and the gas will enter the air storage chamber 112 through the filter element 32 and be extracted by the air suction mechanism 2. Such an arrangement prevents the material and the gas from interfering with each other, thereby improving the filtering effect. In addition, by setting a plurality of partitions 311, the storage chamber 11 is divided into a plurality of material placement chambers 111, which helps to disperse the accumulation of materials, prevent excessive accumulation of materials in a certain area and cause blockage, ensure the smoothness of material flow, and improve the working efficiency of the suction device.

[0036] More specifically, the filter element 32 is made of polyester fiber and has a honeycomb structure. Since the polyester fiber has the characteristics of wear resistance and light weight, the filter element 32 can maintain stable performance during use. Moreover, the honeycomb structure makes the filter element 32 have a higher specific strength and specific stiffness, which can effectively reduce the weight of the structure and improve the load-bearing capacity.

[0037] Specifically, Figure 1 As shown, the back-blowing mechanism 4 includes an air tank 41 and a back-blowing driver 42. The output end of the back-blowing driver 42 is connected to the air tank 41, and can control the air tank 41 to blow air to the filter mechanism 3. Specifically, the filter element 32 will reduce the filtering effect after being used for a period of time. At this time, the back-blowing driver 42 will control the compressed air (or other gas) in the air tank 41 to blow air to the filter element 32 in the filter mechanism 3. Through the high-speed and high-pressure gas flow, the residue on the filter element 32 can be effectively blown off, so that it can restore the filtering function, and the material on the filter element 32 can be dropped in time, thereby improving the material conveying effect. Through the above-mentioned settings, the automatic cleaning of the filter element 32 is realized, which can not only improve the filtering effect and extend the service life of the filter element 32, but also reduce the maintenance cost and improve the production efficiency.

[0038] More specifically, in this embodiment, the backflush driver 42 is a pulse backflush valve, which has the advantages of simple operation, good cleaning effect, and long service life, and is very suitable for use in industrial production. In other embodiments, the backflush driver 42 can be a solenoid valve or a pneumatic valve, as long as it can achieve the above functions, and no further limitation is made here.

[0039] Specifically, Figure 1 As shown, the discharge port 12 is arranged to be inclined downward so that the material can be discharged in time under the action of its own weight, thereby improving the conveying efficiency.

[0040] More specifically, in order to achieve accurate and adjustable material discharge, in this embodiment, the discharge driver 51 uses an electric cylinder and a push rod, and the electric cylinder drives the push rod to extend and retract, thereby driving the discharge door 52 to move on the slide rail, thereby achieving the opening and closing of the discharge port 12. In other embodiments, the discharge driver 51 uses a hydraulic cylinder, and the output end of the hydraulic cylinder is connected to the discharge door 52, which can drive the discharge door 52 to move back and forth, thereby achieving controllable opening and closing of the discharge door 52, thereby improving the operating efficiency and operability of the device.

[0041] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
