DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0026] Please refer to Figures 1-6 , in the embodiments of the utility model, a plastic particle remote wind force conveying device, including spiral feeder 1, be equipped with blanking box 2 at the discharge end of spiral feeder 1, the bottom of blanking box 2 is fixed with blowing pipe 3,

[0027] One end of blowing pipe 3 is connected with feeding fan 4, the other end is connected with Y type flange 6, and the other two ports of Y type flange 6 are connected with elbow 7, and each elbow 7 is connected with one feeding pipe 8, and one branch pipe valve 9 is connected in series on each feeding pipe 8.

[0028] Specifically, two feeding pipes 8 are arranged side by side and clamped on pipe support 10, and pipe support 10 is fixed on the ground. The blowing pipe 3 and the Y type flange 6 are also connected in series with the total valve 5.

[0029] By adopting the above technical scheme, two feeding pipes 8 are arranged side by side and connected with the feeding port of the same material using equipment. During use, when one of the pipelines has a problem, the switching of the working state of the two feeding pipes 8 can be realized by controlling the opening and closing of the branch pipe valve 9. After switching, the other pipeline can be repaired without stopping the machine, without affecting the normal operation of the equipment, so that the equipment can work without stopping. For enterprises, it reduces the loss.

[0030] As a further illustration of the embodiment, the branch valve 9 and the total valve 5 can adopt a manual control butterfly valve or an electric butterfly valve; to realize the pipeline on-off as the main.

[0031] In addition to the above-mentioned can realize the device without stopping work, but also has other ways of use;

[0032] Specific example one:

[0033] When the material equipment can only connect one feeding pipe, two feeding pipes 8, one of which is connected with the feeding port of the material equipment; The other feeding pipe does not need to be too long, when emergency stop feeding is needed, close the feeding of the screw feeder 1, close the pipe valve 9 in the feeding state, and open the pipe valve 9 in the idle state of the feeding pipe, so that the material remaining in the pipe can be blown out to the collection box or negative pressure tank; In this way, the existence of accumulated material is avoided.

[0034] When there is accumulated material in the pipe, it is difficult to transport the material deposited in the pipe at the moment the device is started; The power of the device increases sharply, which may cause the device to be overloaded and burned out; Therefore, through the above scheme, such problems can be avoided.

[0035] Specific example two:

[0036] Two feeding pipes 8 can also be connected with different two material equipment, so that one air conveying device can supply material for two material equipment, and the working state of two feeding pipes 8 can be switched at will, thereby reducing the number of feeding equipment in use, thereby reducing the production cost of enterprises.

[0037] In the embodiment, the screw feeder 1 includes a feeder shell 11, and a feeding screw 13 is arranged inside the feeder shell 11; One end of the feeding screw 13 is matched with a chain wheel 14, and the chain wheel 14 is drivenly connected through a chain and another chain wheel installed on the output shaft of a motor 15; The motor 15 is fixed on the top of the feeder shell 11.

[0038] Specifically, the feeding screw 13 is provided with two feeding screws 13, both ends of the two feeding screws 13 are matched and connected with the feeder shell 11 through bearings. The feeder shell 11 is provided with a discharge port at one end of the bottom, and a discharge tank 2 is fixedly installed below the discharge port;

[0039] A hopper 12 is fixedly installed above the end of the feeder shell 11 away from the discharge port; The feeder shell 11 is fixed on a rack body 16.

[0040] By adopting the above technical solution, when in use, plastic granules are put into the hopper 12, and then the motor 15 drives the two feeding screws 13 to rotate under the cooperation of the sprocket 14 and the toothed chain, thereby spirally pushing the plastic granules into the feeding box 2 from the discharge port; thus realizing the feeding of plastic granules.

[0041] The feeding method using the feeding screw 13 can precisely control the feeding amount, preventing plastic granules from accumulating in the feeding box 2 and thus preventing them from being conveyed by the pneumatic system. Secondly, in the event of an emergency shutdown, it can prevent plastic granules from accumulating in the pipeline, thus affecting the speed of restarting the subsequent equipment, and also prevent excessive starting power from causing the material to be unable to be conveyed normally.

[0042] The working principle of this utility model is as follows: When in use, plastic granules are put into the hopper 12. Then, the motor 15 drives the two feeding screws 13 to rotate under the cooperation of the sprocket 14 and the toothed chain, thereby spirally pushing the plastic granules into the feeding box 2 from the discharge port. The feeding blower 4 inputs high-pressure gas into the blowing pipe 3 to blow the falling plastic granules and transport them along the pipeline.

[0043] Two feed pipes 8 are arranged in parallel and connected to the feed port of the same material-using equipment. During use, when one of the pipes has a problem, the working state of the two feed pipes 8 can be switched by controlling the opening and closing of the branch valve 9. After switching, the other pipe can be repaired without stopping the machine or affecting the normal operation of the equipment, thus achieving uninterrupted operation of the equipment and reducing the losses for the enterprise.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0045] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
