DETAILED DESCRIPTION

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] like Figure 1As shown, the existing animal harmless treatment equipment includes a raw material warehouse 1, a crusher 2, a chemical machine 3, a steam cylinder 4, a buffer warehouse 5, a dust collector 6, a condenser 7, a vacuum tank 8, and a cooling tower 9; the discharge port of the raw material warehouse 1 is arranged above the feed port of the crusher 2, a first conveying auger 10 and a feed valve 11 are arranged between the crusher 2 and the chemical machine 3, a steam inlet pipeline 12 and a steam inlet valve 13 are arranged between the steam cylinder 4 and the chemical machine 3, a discharge valve 19 and a second conveying auger 14 are arranged between the chemical machine 3 and the buffer warehouse 5, a pressure relief pipeline 15 and a pressure relief valve 16 are arranged between the chemical machine 3 and the dust collector 6, one pipeline of the condenser 7 is connected to the dust collector 6 and the vacuum tank 8, another pipeline of the condenser 7 is connected to the circulating pump 17 and the cooling tower 9, and the vacuum tank 8 is connected to the vacuum pump 18. Of course, the whole set of animal harmless treatment equipment also includes an oil press, a centrifuge for purifying the oil produced by the oil press, an oil clearing tank and other equipment. Since the operation of this part of the equipment mainly relies on manual control, this embodiment does not provide a detailed description of this part of the equipment. In addition, all of the above equipment and valves are controlled by a control system, thereby realizing intelligent control of the whole set of equipment.

[0020] Based on the above-mentioned animal harmless treatment equipment, this embodiment provides an intelligent control method for animal harmless treatment equipment, such as Figure 2 As shown, the following steps are included: Step 102, receiving the preparation start signal, closing the discharge valve, and opening the steam inlet valve to the set ratio; wherein, the preparation start signal can be triggered by the staff by clicking the button on the control terminal screen, and then the control system automatically controls the discharge valve of the chemical machine to close, and controls the steam inlet valve to open to 25%, so that the air pressure in the chemical machine gradually increases; since the chemical machine is in a low pressure state after the last round of discharge, this step is to restore the air pressure in the chemical machine to a certain extent, so as to ensure the normal feeding. Specifically, the pressure relief valve has a large pressure relief valve and a small pressure relief valve connected in parallel with each other, and both pressure relief valves need to be closed in this step. The steam inlet pipeline and the steam inlet valve also have two groups, and the two steam inlet valves are respectively the main shaft steam valve and the interlayer steam valve. In this step, both steam valves need to be opened by 25%.

[0021] Step 104, when the control system receives the signal to start preparing, it starts to monitor the air pressure in the chemical machine synchronously. When the air pressure in the chemical machine reaches the set air pressure range, the steam inlet valve is closed, and the first conveying auger and the feed valve are opened; after setting the delay time, the crusher is started and the feed port of the raw material bin is opened; wherein, the control system monitors the air pressure in the chemical machine through the air pressure sensor, and the set air pressure range is specifically 3bar-5bar; since the distance between the crusher and the chemical machine is relatively far, the first conveying auger has two end-to-end connected auger, and the two first conveying auger generally need to be opened at the same time, and the feed valve is located at the feed port of the chemical machine. The set delay time is generally 30s to ensure that when the crusher produces crushed materials, the first conveying auger and the feed valve are in a normal open state, ensuring that the crushed materials are normally output from the crusher to avoid the overflow of the raw materials in the crusher. In this way, after this step, the raw materials enter the crusher from the raw material bin, and the crushed materials produced by the crusher enter the chemical machine through the first conveying auger and the feed valve, completing the automatic feeding.

[0022] Step 106, receiving the feeding stop signal, closing the feed port of the raw material bin, and shutting down the crusher, the first conveying auger, and the feed valve in sequence according to the set interval time; wherein, the feeding stop signal can be triggered by the staff through the button on the screen, or by the material level sensor set in the chemical machine, that is, when the crushed material in the chemical machine reaches the set amount, the feeding is stopped, and the feed port of the raw material bin is immediately closed. However, since there will be residual crushed material in the first conveying auger, the set amount cannot be 100% to avoid excessive crushed material in the chemical machine and affect its normal operation. The set interval time needs to be greater than 2 minutes to ensure safety. First shut down the crusher, and the crusher will stop producing new crushed material; then, the first conveying auger continues to transport the remaining crushed material into the chemical machine; after the set interval time, it can be ensured that the crushed material in the first conveying auger has been fully output, and the first conveying auger can be shut down at this time; after the set interval time after the first conveying auger is shut down, it is ensured that no crushed material continues to enter the chemical machine through the feed valve, and the feed valve can be closed. In addition, as mentioned above, the first conveying augers have two connected in the first place, so when shutting down, the augers close to the crusher can be shut down first, and after a set interval time, the augers close to the chemical machine can be shut down to take into account both safety and energy saving.

[0023] Step 108, receiving the chemical start signal, and opening the steam inlet valve in stages according to the set time until 100%; wherein, the chemical start signal can be triggered by the staff through the button on the screen, or by the relevant signal of the previous step, for example, when the crushed material in the chemical machine reaches the set amount and the feed valve is closed, the chemical start signal is triggered. In order to make the temperature and pressure increase process in the chemical machine more stable and controllable, the steam inlet valve is opened in stages, specifically: 0-1min open 25%, 1-2min open 50%, 2-3min open 75%, 3-4min open 100%. The main shaft steam valve and the interlayer steam valve are synchronously opened in the above-mentioned opening manner.

[0024] Step 110, receiving the chemical process end signal, closing the steam inlet valve, and shutting down the chemical process machine at the same time; wherein, the chemical process end signal can be triggered by the staff through the button on the screen, or it can be automatically triggered after the set chemical process time. The chemical process start time can be when the steam inlet valve is opened to 100%. After the chemical process is completed, the steam inlet valve is automatically closed and the chemical process machine is shut down at the same time.

[0025] Step 112, receiving the pressure relief start signal, starting the circulation pump, the cooling tower, and opening the pressure relief valve in stages; wherein the pressure relief start signal can be triggered by the staff through the button on the screen, or it can be automatically triggered after the end of step 110. This step is mainly used to discharge the steam in the chemical processing machine for the drying process, and at the same time use the condenser, the circulation pump, and the cooling tower for heat exchange to recycle the moisture in the steam. In order to prevent the direct opening of the pressure relief valve from causing the material to block the pressure relief pipeline and ensure the safety of the equipment, the pressure relief valve adopts a proportional opening method, which can be specifically: 0-1min open 25%, 1-2min open 50%, 2-3min open 75%, 3-4min open 100%. In addition, the pressure relief valve includes a small pressure relief valve and a large pressure relief valve connected in parallel. Therefore, the small pressure relief valve can be opened proportionally to 100% first, and then the large pressure relief valve can be opened proportionally to 100% to further ensure safety.

[0026] Step 114, during the pressure relief process, monitor the air pressure and temperature in the chemical processing machine. When the air pressure and temperature in the chemical processing machine are lower than the set value and reach the set time, it is allowed to receive the drying start signal to ensure the balance of inlet and outlet air during the subsequent drying process.

[0027] Step 116, receiving the drying start signal, turning on the vacuum pump, opening the steam inlet valve in stages according to the set time until 100%, and turning on the chemical processing machine; wherein, the drying start signal can be triggered by the staff through the button on the screen, or it can be automatically triggered when the air pressure in the chemical processing machine is less than 0.01 bar in step 114. In order to make the heating process in the chemical processing machine more stable and controllable, the steam inlet valve is opened in stages, specifically: opening 25%, opening 50%, opening 75%, opening 100%, and automatically adjusting according to the set value. The main shaft steam valve and the interlayer steam valve adopt the above-mentioned opening method synchronously. Since the pressure relief valve is in an open state at this time, the steam in the chemical processing machine can be quickly discharged after turning on the vacuum pump, that is, the steam is quickly discharged after heat exchange with the crushed material, ensuring the drying efficiency of the crushed material.

[0028] Step 118, receiving the drying end signal, closing the steam inlet valve; wherein, the drying end signal can be triggered by the staff through the button on the screen, or it can be automatically triggered after the set drying time, that is, it is triggered after the set time in step 116. At this time, the steam inlet valve is closed, and steam is no longer charged into the chemical machine, while the pressure relief valve and the vacuum pump are still in the open state, that is, the chemical machine is continuously evacuated to discharge the remaining steam, which is conducive to the continued drying of the crushed material.

[0029] Step 120, receiving the discharge start signal, starting the second conveying auger and the buffer bin, and the chemical machine rotates forward and reverse in sequence according to the set time; wherein, the discharge start signal can be triggered by the staff through the button on the screen, and can also be triggered by the material level signal in the buffer bin, that is, when there is enough space in the buffer bin to receive the crushed material, and after step 118 is completed, the discharge start signal is triggered. Start the second conveying auger to transport the crushed material from the chemical machine to the buffer bin, and at the same time, the stirring mechanism in the buffer bin is activated to mix the received crushed material with the crushed material in the buffer bin. The chemical machine rotates forward and reversely to avoid the crushed material from being deposited in the chemical machine and to ensure the completeness of the crushed material discharge.

[0030] Step 122, after the chemical machine is reversed, the chemical machine, circulation pump, cooling tower, and vacuum pump are shut down, and the discharge is completed.

[0031] Afterwards, the staff can control the operation of equipment such as oil presses and centrifuges through the control system screen to complete the subsequent oil pressing process and obtain by-products.

[0032] like Figure 3 As shown, the embodiment of this specification also provides an intelligent control system for animal harmless treatment equipment, including: A preparation module is used to receive a preparation start signal, close the feed valve, and open the steam inlet valve to a set ratio; The feeding module is used to monitor the air pressure in the chemical processing machine. When the air pressure in the chemical processing machine reaches the set air pressure range, the steam inlet valve is closed, the first conveying auger and the feed valve are opened; after the set delay time, the crusher is started and the feed port of the raw material bin is opened; Receive the feeding stop signal, close the feed port of the raw material bin, and shut down the crusher, the first conveying auger, and the feed valve in sequence according to the set interval time; The chemical control module is used to receive the chemical control start signal and open the steam inlet valve in stages according to the set time until 100%; Receive the chemical system end signal, close the steam inlet valve, and shut down the chemical system at the same time; A pressure relief module is used to receive a pressure relief start signal, start a circulation pump and a cooling tower, and open a pressure relief valve in stages; Monitor the air pressure and temperature in the chemical machine. When the air pressure and temperature in the chemical machine are lower than the set value and reach the set time, it is allowed to receive the drying start signal; The drying module is used to receive the drying start signal, start the vacuum pump, open the steam inlet valve in stages according to the set time until 100%, and start the chemical processing machine; Receive the drying end signal and close the steam inlet valve; The discharging module is used to receive the discharging start signal, start the second conveying auger and the buffer bin, and the chemical processing machine rotates forward and reverse in sequence according to the set time; After the chemical machine is reversed, shut down the chemical machine, circulation pump, cooling tower and vacuum pump.
