Description

Technical Field

[0001] The utility model relates to the technical field of feed production, in particular to a feed head and tail collection system. Background Art

[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] As people's awareness of food safety and breeding safety gradually increases, the feed quality control system is constantly improving, and the requirements for feed quality and safety are also increasing. In the process of feed production, due to reasons such as downtime and material number conversion, it is inevitable that there will be head and tail materials. Head and tail materials refer to the waste and residual materials generated in the process of feed production.

[0004] After evaluation, it is found that the quality of the raw materials and tail materials is controllable in most cases and can be put into use again to reduce material loss. According to quality requirements, the raw materials can be put into use in the same batch of the same material number, and the tail materials must be put into use in the next batch of the same material number to ensure that the quality risk is controllable. The number of material numbers determines the type of tail materials, and the output of the material number affects the storage time of the tail materials. Therefore, the management of tail materials at the production site cannot be ignored. If you are not careful, it may bring quality risks into the production line.

[0005] In the existing automatic feed production system, an elevator is used to transport the head and tail materials to the semi-finished product warehouse for processing. However, the head and tail materials are collected at the packaging port and then transported together. The transportation is not timely, the transportation efficiency is low, and the feed storage amount in the silo is not monitored in real time, which makes it inconvenient for operators to understand the storage situation of the head and tail materials in time, and the collection efficiency is low.

[0006] In addition, dust is easily generated during the production process of feed, and dust pollution can easily block the feed delivery pipeline, causing transportation difficulties. Utility Model Content

Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0042] As introduced in the background technology, the material head and tail collection system in the prior art cannot collect the material head and tail in real time during the material conveying process, and the material head and tail collection efficiency is low. In order to solve the above technical problems, the utility model proposes a material head and tail collection system.

The feed port of the pneumatic tee 3 is connected with the discharge port of the finished product flow pipe 1. One discharge port of the pneumatic tee 3 is connected with the normal finished product production line 2 through a feed pipe; the other discharge port of the pneumatic tee 3 is connected with the feed port of the rotary distributor 5 through a feed pipe. Four discharge ports are opened below the rotary distributor 5.

[0044] The feed port of the rotary distributor 5 is connected to a dust collector 4, and a negative pressure environment is formed inside the rotary distributor 5 and the silo 6 through the dust collector 4 to remove dust from the transported feed to avoid particle blockage. An upper level device is installed at the upper part of the silo 6 along the height direction (the highest level of feed in the silo 6), and a lower level device is installed at the bottom of the silo 6 along the height direction (the lowest level of feed in the silo 6). The upper level device and the lower level device are electrically connected to the control unit, and the control unit is electrically connected to the rotary distributor 5, the first discharge valve, the second discharge valve and the pneumatic tee 3 respectively.

[0046] The working process of this embodiment is as follows:

[0047] During the feed transportation process, when it is necessary to collect the head and tail of the feed, the operator closes the pneumatic valve of the pneumatic tee 3 corresponding to the normal finished material production line 2 through the PLC controller, and starts the pneumatic valve of the rotary distributor 5 corresponding to the pneumatic tee 3. The feed flows out from the finished product flow pipe 1 and flows into the rotary distributor 5 through the pneumatic tee 3. The rotary distributor 5 selects the designated bin position through the travel switch, and the feed enters the corresponding silo 6 according to the designated bin position. When the material in the silo 6 reaches the upper level device, the upper level device sends an electrical signal to the control unit, and the control unit controls the rotary distributor 5 to change bins until the collection of the head and tail of the feed is completed.

[0048] When the head and tail of the material are put into use, the PLC controller sends an electrical signal to the second discharge valve and the first discharge valve of the corresponding silo 6 to open the first discharge valve and the second discharge valve.

The PLC controller is electrically connected to the coil of the intermediate relay, the audible and visual alarm is electrically connected to the normally open switch of the intermediate relay, and the normally open switch of the intermediate relay is electrically connected to the power supply.

[0051] When the material level of the feed in any silo 6 reaches the height of the upper material level device, the upper material level device sends an electrical signal to the coil of the intermediate relay, the coil is energized, the normally open switch is closed, and the sound and light alarm sounds an alarm, thereby prompting the operator.

[0052] As an implementation mode, a silo wall vibrator is installed on the side wall of the silo 6, and the silo wall vibrator is used to prevent the feed from being accumulated in the silo 6, thereby improving the circulation rate of the feed.
