[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] The equipment is mainly used for the production of raw materials such as PA6 / PP0, glass fiber reinforced nylon composite materials, and polyphenylene ether. The self-circulation function of the utility model mainly relies on two sets of dilute phase pneumatic conveying systems. When conveying materials through the first dilute phase pneumatic conveying system and the second dilute phase pneumatic conveying system, it is necessary to use a Roots blower or an air compressor to generate compressed air or gas as the power source of the two sets of dilute phase pneumatic conveying systems, and feed the materials into the feed pipe 2 or the feed pipe 7, and then use the flow of gas to transport the materials to the destination, thereby ensuring the self-circulation function of the self-circulating finished product warehouse.

[0038] like Figure 1 - Figure 5 As shown, the utility model provides a technical solution: a self-circulating finished product warehouse, including a finished product warehouse main body 1, a first dilute phase pneumatic conveying system is connected to the upper left of the finished product warehouse main body 1, which is used to convey materials generated in the production process to the finished product warehouse main body 1 for storage, the first dilute phase pneumatic conveying system includes a feed pipe 2, a separation tank 3 and an external feeder connected to the feed pipe 2, and a second dilute phase pneumatic conveying system is connected to the upper right of the finished product warehouse main body 1, which is used to convey materials stored inside the finished product warehouse main body 1 to the production equipment, and the second dilute phase pneumatic conveying system includes a feed tank 5, an air supply pipe 6 connected to the air source and a feed pipe 7 connected to the production equipment.

[0039] By setting up a first dilute phase pneumatic conveying system and a second dilute phase pneumatic conveying system, the first dilute phase pneumatic conveying system is used to convey the powder or granular materials generated in the production process to the finished product warehouse body 1 for storage and subsequent processing, and the second dilute phase pneumatic conveying system is used to convey the materials to the production equipment, so that the finished product warehouse has a self-circulation function, so that the equipment can realize continuous and efficient transportation and recycling of materials, improve production efficiency and resource utilization, and reduce energy consumption and environmental pollution

[0040] The separation tank 3 includes a cover body 31, an upper tank body 32 and a lower tank body 33. The cover body 31 and the upper tank body 32, and the upper tank body 32 and the lower tank body 33 are detachably connected and fixed by locking parts, so as to facilitate cleaning and maintenance of the interior of the separation tank 3.

[0041] The top of the cover body 31 is connected to the feed pipe 2, and a spiral feed conduit 311 is welded and fixed on the inner top wall of the cover body 31. An integrally formed exhaust pipe 321 is provided on the side wall of the upper tank body 32 and near the upper right corner. A spiral plate 322 is installed on the inner side of the upper tank body 32 and below the exhaust pipe 321.

[0042] The feed conduit 311 allows the airflow containing the material to enter the separation tank 3 tangentially. With the cooperation of the feed conduit 311 and the spiral plate 322, the airflow can move downward along the spiral plate 322 and generate centrifugal force. Under the action of the centrifugal force, the heavier solid particles are thrown to the wall of the device and move downward along the wall, and finally fall into the collection bucket 331 at the bottom. At the same time, the lighter gas will be discharged to the outside through the exhaust pipe 321.

[0043] A collecting bucket 331 is installed on the inner side of the lower tank body 33 and near the top. A herringbone plate 332 is welded and fixed to the inner side of the lower tank body 33 and below the collecting bucket 331. A cone 333 is provided at the top center of the herringbone plate 332. The collecting bucket 331 and the cone 333 cooperate with each other to prevent the gas below the collecting bucket 331 from flowing upward and to prevent the separated materials from being carried away by the air. At the same time, the herringbone plate 332 can further restrict and guide the materials, facilitating the materials to enter the interior of the finished product warehouse body 1 while preventing the materials in the finished product warehouse body 1 from escaping upward.

[0044] like Figure 2 As shown, the first dilute phase pneumatic conveying system also includes a feed branch pipe 4 arranged on the top of the finished product warehouse body 1, the top of the feed branch pipe 4 is sleeved with a hose 41 connected to the exhaust pipe 321, the left side of the feed branch pipe 4 is connected to an outlet pipe 42, and a bag dust collector 43 is installed at the end of the outlet pipe 42.

[0045] The separated gas inside the separation tank 3 flows to the inside of the feed branch pipe 4 through the exhaust pipe 321 and the hose 41, and flows to the outlet pipe 42 under the guidance of the outlet pipe 42, and is further separated and filtered by the bag dust collector 43, so that the tiny material particles mixed in the gas fall into the finished product warehouse body, thereby improving the utilization efficiency of the material products.

[0046] like Figure 4 and Figure 5 As shown, the feed tank 5 is fixedly connected to the external steel frame structure through a fixing frame. The feed tank 5 consists of three parts: a cover body, an upper tank body and a lower tank body. The cover body and the upper tank body, and the upper tank body and the lower tank body are detachably connected and fixed by locking parts, which is convenient for cleaning and maintenance of the interior of the feed tank 5.

[0047] A suction pipe 51 extending to the interior of the finished product warehouse body 1 is installed at the bottom of the supply tank 5. The suction pipe 51 is a hose structure, which is convenient for sucking materials in the finished product warehouse body 1. A suction head 511 is installed at the bottom of the finished product warehouse body 1. A sleeve 52 is installed at the bottom of the supply tank 5 and on the outside of the suction pipe 51. The bottom of the sleeve 52 is fixedly connected to the finished product warehouse body 1. The sleeve 52 plays a protective role on the outside of the suction pipe 51. At the same time, it can be supported and fixed between the finished product warehouse body 1 and the supply tank 5.

[0048] The air supply pipe 6 is arranged at the lower right corner of the supply tank 5 and extends to the interior of the supply tank 5. A conical cover 61 is welded and fixed on the top of the air supply pipe 6. The supply pipe 7 is fixedly connected to the top of the supply tank 5. A collection cover 71 is installed at the bottom end of the supply pipe 7 and located inside the supply tank 5.

[0049] The air supply pipe 6 is connected to a Roots blower or an air compressor, and can continuously deliver high-pressure airflow to the air supply pipe 6. After being guided by the conical cover 61, a continuously upward-flowing airflow can be formed inside the supply tank 5, and a negative pressure suction force is generated at the bottom end of the supply tank 5, so that the suction pipe 51 and the suction head 511 cooperate to suck the material in the finished product warehouse body 1 into the supply tank 5, and under the drive of the airflow and the guidance of the collection cover 71, the material is brought into the supply pipe 7.

[0050] Working principle: the feed pipe 2 and the air supply pipe 6 are both connected to the external air source. When the material generated in the production process enters the feed pipe 2, the material enters the interior of the separation tank 3 under the drive of the airflow. Under the cooperation of the feed conduit 311 and the spiral plate 322, the airflow moves downward along the spiral plate 322 and generates centrifugal force. Under the action of the centrifugal force, the heavier solid particles are thrown to the wall of the device. After that, the collecting bucket 331, the herringbone plate 332 and the cone 333 cooperate with each other to make the solid material fall into the finished product bin body 1 for storage. At the same time, the lighter gas flows into the feed branch pipe 4 through the exhaust pipe 321 and the hose 41. After further filtration by the bag dust collector 43, the lighter material falls into the finished product bin body 1.

[0051] Furthermore, high-pressure air flows into the air supply pipe 6, and is guided by the conical cover 61 to form a continuously upward-flowing airflow inside the supply tank 5, so that the suction pipe 51 and the suction head 511 cooperate to suck the material in the finished product warehouse body 1 into the supply tank 5. Driven by the airflow and guided by the collecting cover 71, the material is brought into the supply pipe 7, so that the finished product warehouse has a self-circulation function, so that the equipment can realize continuous and efficient transportation and recycling of materials, improve production efficiency and resource utilization, and reduce energy consumption and environmental pollution.

[0052] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
