As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The utility model provides a pipe chain conveyor capable of recovering powder, which comprises:

the chain wheel 2, the tray 3 and the scraper 5; the chain wheel 2 is horizontally arranged in the case 1, the tray 3 is arranged below the chain wheel 2, a collecting groove 4 is formed on the tray 3, and the collecting groove 4 extends from an outlet of a belt material pipe 6 to an inlet of a return pipe 7 along a moving path of the scraper 5;

the chain wheel 2 which is horizontally placed can enable powder attached to the scraper 5 to fall into the collecting tank 4 under the action of gravity, the collecting tank 4 extends to the inlet of the return pipe 7 from the outlet of the material carrying pipe 6 along the moving path of the scraper 5, and the powder can fall into the collecting tank 4 as long as the powder falls off from the scraper 5 no matter where the scraper 5 moves; when powder in the collecting tank 4 is accumulated to a certain height, the scraper 5 can also scrape the powder and send the powder into the return pipe 7 to convey the dropped powder.

It should be noted that, since the sprocket 2 of the present apparatus is placed horizontally, a horizontal chassis is adopted.

Specifically, collecting vat 4 internal surface is the circular arc setting of indent, and such design can make the powder that drops in collecting vat 4 collect, and when the powder collects the take the altitude, scraper blade 5 scrapes away the powder and sends into in return stroke pipe 7, in this embodiment, collecting vat 4's width and return stroke pipe 7, take the width of material pipe 6 unanimously, and collecting vat 4 and return stroke pipe 7, take the junction of material pipe 6 seamless, avoid the powder to take place to leak by the collecting vat 4 in-process powder that gets into return stroke pipe 7 like this.

Specifically, the scraper 5 is suspended in the collecting tank 4, so that the scraper 5 is prevented from touching the collecting tank 4 in the moving process, and the scraper 5 is damaged and generates noise; the collecting groove 4 at least semi-surrounds the scraper 5, and the linear distance from the outer peripheral surface of the scraper 5 to the inner surface of the collecting groove 4 is smaller than the thickness of the chain 22, so that the collecting groove 4 can limit the scraper 5, and the chain 22 is prevented from being separated from the chain wheel 2.

In this embodiment, the linear distance between the scraper 5 and the collecting tank 4 is ten millimeters, and when the accumulated powder is more than ten millimeters thick, the scraper 5 can push the powder to convey the powder.

Specifically, the inner surface of the collecting tank 4 is smooth, so that the powder is prevented from being adhered to the inside of the collecting tank 4 after being accumulated.

Further, consider that current pipe chain conveyer when chain 22 drops sprocket 2, all need dismantle sprocket 2 or chain 22 and install, so in this embodiment, slide the support frame 9 with sprocket 2 place and set up in quick-witted case 1 to be connected with drive arrangement, through drive arrangement pulling sprocket 2, increase or reduce the distance between two sprockets 2 (current pipe chain conveyer all is two sprockets, driven sprocket of a drive sprocket), be convenient for install chain 22 that drops and the more loose chain 22 that rises.

Specifically, the sprocket 2 is installed on the rotating shaft 8 through a bearing, the rotating shaft 8 is fixedly arranged on the supporting frame 9, two opposite side walls in the case 1 are symmetrically provided with the U-shaped slide ways 10, the supporting frame 9 is slidably arranged in the U-shaped slide ways 10, in the embodiment, the supporting frame 9 is of a plate type structure, and two ends of the supporting frame 9 are inserted into the U-shaped slide ways 10.

Specifically, near one of them U-shaped slide 10 is provided with strip frame 12, has set firmly contact 13 on strip frame 12, install travel switch 11 that is used for responding to contact 13 on the support frame 9 for the moving range of restriction support frame 9 avoids support frame 9 to remove the super scope, causes the damage of chain 22.

Specifically, the supporting frame 9 is connected with a driving device, and the driving device can drive the supporting frame 9 to move back and forth along the U-shaped slide way 10.

Specifically, the driving device comprises a pressure spring 14 and a threaded rod 17;

the bottom of the pressure spring 14 is fixedly arranged on a pressure spring seat 15, the top of the pressure spring 14 is fixedly provided with a pressure spring sleeve (not shown in the figure), and a nut mounting rack 16 which is at least as high as the pressure spring 14 is constructed on the pressure spring seat 15;

the side edge of the first bolt 18 is fixedly arranged on the nut mounting frame 16, the side edge of the second bolt 19 is fixedly arranged on the support frame 9, a third bolt 20 is fixedly sleeved on the threaded rod 17, one end of the threaded rod 17 is in threaded connection with the first bolt 18, and the other end of the threaded rod 17 is in threaded connection with the second bolt 19, so that when the third bolt 20 rotates, the third bolt 20 drives the threaded rod 17 to abut against or be far away from the pressure spring sleeve;

when a chain 22 between two chain wheels 2 needs to be tensioned, a third bolt 20 is screwed in the forward direction, the third bolt 20 drives a threaded rod 17 to be in threaded connection with a first bolt 18, the threaded rod 17 moves in the direction close to a second bolt 19, the threaded rod 17 gradually does not extrude a pressure spring 14 through a pressure spring sleeve, the pressure spring 14 expands, as a pressure spring seat 15 is fixedly arranged on the side wall of a case 1 close to a material carrying pipe 6 and a return pipe 7, a support frame 9 moves in the direction far away from the pressure spring seat 15, the distance between the two chain wheels 2 is enlarged, the chain 22 is tensioned, but when the support frame 9 moves to the position close to a contact 13, a travel switch 11 on the support frame 9 senses the contact 13 and sends out warning through a buzzer or a warning lamp to prompt a worker to stop twisting the third bolt 20; similarly, when the chain 22 falls off, the third bolt 20 is twisted reversely.

Furthermore, a color indication paste can be pasted on the nut mounting frame 16 to prompt the movable limit position of the threaded rod 17, so that the situation that the threaded rod 17 excessively extrudes the compression spring 14 to cause damage to the spring 14 is avoided.

The working principle and the working process of the utility model are as follows:

the chain wheel 2 is horizontally arranged in the case 1, the tray 3 is arranged below the chain wheel 2, when the scraper 5 enters the case 1 from the material carrying pipe 6, the falling powder can fall into the collecting tank 4 on the tray 3 under the action of self weight, and when the powder in the collecting tank 4 is accumulated to a certain thickness, the powder accumulated in the collecting tank 4 is pushed into the return pipe 7 by the scraper 5 of the collecting tank 4, so that the purpose of recovering the powder is realized;

collecting vat 4 is at least half surrounding scraper blade 5, and the straight line distance of scraper blade 5 outer peripheral face to collecting vat 4 internal surface is less than the thickness of chain 22, can make collecting vat 4 play limiting displacement to scraper blade 5, prevents that chain 22 from breaking away from sprocket 2.

The embodiments of the present invention have been described in detail, but the description is only for the preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made within the scope of the present invention should be covered by the present patent.
