Description

Technical Field

[0001] This utility model belongs to the field of animal feed production technology, and in particular relates to a post-oil spraying and weighing cabinet device. Background Technology

[0002] In the current increasingly competitive feed industry, feed mills are committed to reducing raw material costs while ensuring product quality standards are met. As a key energy source in feed, oils typically need to be added at a rate of 8% in fattening feed (i.e., 80 kg of oil per ton of finished feed). Based on an annual output of 150,000 tons of finished feed, the annual oil consumption would reach as high as 12,000 tons. Currently, most feed producers use soybean oil as an added oil. However, soybean oil prices fluctuate frequently due to international trade conditions, which undoubtedly brings uncertainty to feed production costs. With the continuous advancement of feed formulation technology, more and more new types of oils are being applied to feed to improve its nutritional composition or palatability. This demand has led to the development of oil spraying and weighing cabinet devices.

[0003] Existing oil spraying and weighing cabinet devices have revealed many problems in practical applications. First, in the oil weighing process, the accuracy of oil ratio in these devices is difficult to guarantee. Because air bubbles are easily generated during the mixing of various oils, these air bubbles occupy a certain space, causing a deviation between the measured oil weight and the actual weight. In the actual production process, the accuracy of the amount of oil added directly affects the nutritional composition and quality stability of the feed. Second, the oil filtration effect is poor. The oil used in feed production may contain various impurities, such as solid particles and fibers. If these impurities are not effectively filtered and directly enter the subsequent processes, they will affect the uniform mixing of the oil, reduce the oil quality, and thus affect the quality and palatability of the feed. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the prior art by providing a grease post-spraying weighing cabinet device.

[0005] To achieve the above objectives, the utility model adopts the following technical solution: a grease post-spray weighing cabinet device, including a cabinet frame, a mixing oil tank inside the cabinet frame, a mixing component on the mixing oil tank, several oil inlet pipes installed on the mixing oil tank, filters and flow meters respectively installed on the several oil inlet pipes, a first shut-off valve at the discharge end of the mixing oil tank, an oil storage tank installed at the other end of the first shut-off valve, a stirring device installed on the oil storage tank, supports on the outer periphery of the mixing oil tank and the oil storage tank respectively, a pressure sensor connected to the cabinet frame on the support, an electric heater on the oil storage tank, and a spray pump connected to the oil discharge end of the oil storage tank on the cabinet frame.

[0006] By adopting the above technical solution, with the cabinet frame as support, the mixing tank and mixing components work together to ensure that various oils are fully and evenly mixed; the oil inlet pipe is equipped with a filter and flow meter to filter impurities and determine whether the filter is clogged; the first shut-off valve controls the discharge of oil to the storage tank, and the stirring device maintains its uniformity; the pressure sensor weighs in real time to monitor the use and remaining status of oil; the electric heater regulates the oil temperature to meet process requirements; and the oil injection pump achieves accurate post-spraying.

[0013] Optionally, the oil inlet pipe is equipped with a second shut-off valve and a manual valve, and the outer periphery of the oil inlet pipe is provided with a pipe seat, and the pipe seat is provided with a fixing seat connected to the cabinet frame.

[0014] By adopting the above technical solution, the second shut-off valve and the manual valve installed on the oil inlet pipeline can achieve dual control. The second shut-off valve controls the flow of grease, and the manual valve serves as a backup or auxiliary control method. It can be manually operated when needed to ensure the reliability and safety of oil inlet. The pipe seat and the fixed seat firmly fix the oil inlet pipeline on the cabinet frame to prevent the pipeline from shaking during the flow of grease.

[0015] Optionally, the outer periphery of the oil inlet pipe is provided with a plurality of oil holes, and the plurality of oil holes are located inside the mixing tank.

[0016] By adopting the above technical solution, the opening of several oil holes on the outer periphery of the oil inlet pipe allows the grease to be sprayed evenly from multiple positions when it enters the mixing tank through the oil inlet pipe. This increases the contact area between the grease and other greases in the tank, which is conducive to the rapid mixing and dispersion of the grease, improves the mixing efficiency, makes the mixing more uniform, and further improves the quality of the grease.

[0017] Optionally, the filter element includes a filter box connected to the oil inlet end of the oil inlet pipe. An end cap is installed on the upper surface of the filter box, and a filter screen cylinder is provided on the lower surface of the end cap.

[0018] By adopting the above technical solution, the filter screen on the filter element can filter the incoming grease and remove impurities. The connecting pipe and docking seat connect the oil supply pipe to the filter box, facilitating the entry of grease into the filtration system. The impeller rotates under the flow of grease, synchronously driving the rotating shaft. The rotation of the rotating shaft drives the cleaning component to rotate as well, thereby cleaning the inner wall of the filter screen, preventing impurities from clogging the filter screen, ensuring the filtration effect, extending the service life of the filter screen, reducing the number of equipment maintenance, and improving production efficiency.

[0019] Optionally, the cleaning component includes a mounting sleeve installed on the outer periphery of the rotating shaft, the outer periphery of the mounting sleeve is provided with a connecting rod, and the other end of the connecting rod is provided with a cleaning brush.

[0020] By adopting the above technical solution, the mounting sleeve of the cleaning component is installed on the outer periphery of the rotating shaft, and the connecting rod connects the cleaning brush to the mounting sleeve, so that the cleaning brush can rotate with the rotating shaft. During the rotation, the cleaning brush cleans the inner peripheral wall of the filter screen cylinder, effectively removing impurities attached to the filter screen cylinder, preventing impurities from accumulating and affecting the filtration effect, ensuring that the filter screen cylinder always maintains good filtration performance, and ensuring the purity of the grease entering the mixing oil tank.

[0021] Compared with the prior art, the beneficial effects of this utility model are: 1. Through the coordinated operation of the mixing tank and mixing components, a variety of oils can be thoroughly and evenly mixed within the tank. Furthermore, by equipping the mixing tank with mixing components, after each type of oil is discharged, the stirring action allows air bubbles entrained in the oil to escape fully, eliminating weighing errors caused by cavitation. This ensures precise oil ratios and weights after mixing, with minimal error.

[0022] 2. The oil inlet pipe is equipped with a filter element, which can effectively filter impurities in the grease, ensuring the purity of the grease entering the mixing tank and avoiding the adverse effects of impurities on subsequent equipment and processes. At the same time, the design of the impeller, shaft and cleaning components in the filter element can realize automatic cleaning of the inner wall of the filter screen, preventing impurities from clogging the filter screen, extending the service life of the filter screen, reducing the number of equipment maintenance, improving production efficiency, and ensuring the continuous and stable filtration effect.

[0023] 3.

[0030] The mixing tank 2 is equipped with a mixing assembly 3, which includes a motor 31 mounted on the surface of the cover plate 22. The output end of the motor 31 is equipped with a drive shaft 32 extending into the tank body 21. A mixer 33 is mounted on the outer periphery of the drive shaft 32. Several mounting holes 34 are provided on the outer periphery of the drive shaft 32 for mounting the mixer 33. The motor 31 provides power to the drive shaft 32, which drives the mixer 33 to rotate. During the rotation, the mixer 33 thoroughly stirs and mixes the various oils in the tank body 21, so that the oils can be mixed evenly, improving the consistency of oil quality and ensuring the accuracy of oil addition in subsequent feed production. At the same time, it allows air bubbles entrained in the oil to escape fully, eliminating weighing errors caused by cavitation.

[0031] The mixing tank 2 is equipped with several oil inlet pipes 4. The oil inlet pipes 4 are equipped with a second shut-off valve 41 and a manual valve 42. The outer periphery of the oil inlet pipes 4 is provided with a pipe seat 43. The pipe seat 43 is provided with a fixed seat 44 that is connected to the cabinet frame 1.

The pipe seat 43 and the fixing seat 44 firmly fix the oil inlet pipe 4 to the cabinet frame 1 to prevent the pipe from shaking during the flow of grease and avoid problems such as loose connections and leakage caused by pipe shaking, thus ensuring the normal operation of the device. The oil holes 45 on the outer periphery of the pipe allow the grease to be sprayed evenly from multiple positions when it enters the mixing oil tank 2 through the oil inlet pipe 4, increasing the contact area between the grease and other greases in the tank, which is conducive to the rapid mixing and dispersion of the grease, improving the mixing efficiency and making the mixing more uniform.

[0032] A filter element 5 and a flow meter 6 are respectively installed on several of the oil inlet pipes 4. The filter element 5 includes a filter box 51 connected to the oil inlet end of the oil inlet pipe 4. An end cover 52 is installed on the upper surface of the filter box 51. The filter box 51 is connected to the end cover 52 by a threaded ring 521. A sealing gasket 522 is installed on the lower surface of the end cover 52.

The connecting pipe 54 and the docking seat 55 connect the oil supply pipe to the filter box 51, facilitating the entry of grease into the filtration system. The impeller 57 rotates under the drive of the grease flow, which in turn drives the rotating shaft 56 to rotate. The rotating shaft 56 drives the cleaning component 58 to clean the inner circumferential wall of the filter cylinder 53, effectively removing impurities attached to the filter cylinder 53, preventing the accumulation of impurities from affecting the filtration effect, ensuring that the filter cylinder 53 always maintains good filtration performance, ensuring the purity of the grease entering the mixing tank 2, extending the service life of the filter cylinder 53, reducing the number of equipment maintenance times, and improving production efficiency. The flow meter 6 is installed between the filter element 5 and the second shut-off valve 41. The flow meter 6 can accurately measure the amount of grease entering the mixing tank 2. When the flow rate of grease entering the mixing tank 2 decreases, it indicates that the filter element 5 is blocked and needs to be disassembled and cleaned.

[0033] The discharge end of the mixing tank 2 is provided with a first shut-off valve 7, and the other end of the first shut-off valve 7 is provided with an oil storage tank 8. The oil storage tank 8 is provided with a stirring device 9. The outer periphery of the mixing tank 2 and the oil storage tank 8 are respectively provided with a support 10. The support 10 is provided with a pressure sensor 11 connected to the cabinet frame 1. The oil storage tank 8 is provided with an electric heater 12. The first shut-off valve 7 controls the discharge of mixed oil from the mixing tank 2 to the storage tank 8. The storage tank 8 is used to store the uniformly mixed oil. The stirring device 9 continuously stirs the oil in the storage tank 8 to ensure the uniformity of the oil and prevent sedimentation or stratification. The pressure sensor 11 monitors the weight change of the storage tank 8 in real time, which can accurately determine the amount of oil used and the remaining amount. The pressure sensor 11 on the mixing tank 2 can monitor the weight of the oil poured in. The electric heater 12 can heat the oil in the storage tank 8 according to different process requirements to meet the oil temperature requirements of different feed production.

[0034] The cabinet frame 1 is equipped with an oil injection pump 13 connected to the oil discharge end of the oil storage tank 8. The oil injection pump 13 can accurately spray the oil stored in the oil storage tank 8 to realize the post-oil injection operation, ensuring the accuracy and uniformity of oil addition, improving the quality of feed products, and meeting the process requirements for oil addition in the feed production process. The cabinet frame 1 is equipped with a cabinet door, on which an observation window and a control panel are installed. The observation window allows operators to observe the internal working status of the device at any time and promptly detect any potential problems. The control panel centralizes various control buttons and display interfaces of the device. Operators can conveniently operate and set various functions of the device through the control panel to achieve intelligent control of the entire device, improving the convenience of operation and production efficiency.

[0035] The working principle of the above embodiments is as follows: According to the formula set by the user, the external independent control device opens the oil drain valves of the two oil drain pipes respectively to inject oil into the device, and at the same time sends an oil injection signal to the weighing cabinet control system. After receiving the oil injection signal, the weighing cabinet control system opens the second shut-off valve 41 on the corresponding oil inlet pipe 4, and the grease is evenly sprayed into the mixing oil tank 2 through the oil hole 45 on the oil inlet pipe 4. During the grease injection process, the filter cylinder 53 filters the incoming grease, removes impurities, and ensures the purity of the grease. The impeller 57 rotates under the influence of the grease flow, which in turn drives the rotating shaft 56 to rotate. The cleaning parts 58 on the rotating shaft 56 clean the inner wall of the filter cylinder 53 to prevent the accumulation of impurities from affecting the filtration effect. Meanwhile, the flow meter 6 monitors the flow rate of grease entering the mixing tank 2 in real time and feeds the data back to the weighing cabinet control system. When the grease flow rate decreases, it indicates that the filter element 5 is severely clogged, and the weighing cabinet control system issues an alarm, prompting the operator to disassemble and clean the filter element 5. The pressure sensor 11 on the mixing tank 2 continuously detects the increase in the weight of the grease in the tank and feeds back the weight data to the weighing cabinet control system in real time. When the weight of the grease in the mixing tank 2 reaches the preset target value for the first pipeline, the weighing cabinet control system closes the second shut-off valve 41 on the pipeline and sends a stop oil injection signal to the external control device. The external control device stops discharging oil into the first pipe, and then opens the second pipe to inject oil according to the formula requirements. The second pipe repeats the working process of the first pipe until the total weight of the oil in the mixing tank 2 reaches the set target value. The weighing cabinet control system closes the second shut-off valve 41 on the second oil pipe and sends the end oil discharge signal to the external control device. After the oil filling is completed, the weighing cabinet control system turns on the motor 31 in the mixing component 3. The motor 31 drives the transmission shaft 32 to rotate. The mixer 33 on the transmission shaft 32 thoroughly stirs and mixes the various oils in the mixing tank 2, so that the air bubbles entrained in the oil can escape completely, eliminating the weighing error caused by cavitation. After the stirring is completed, the weighing cabinet control system turns off the motor 31. The weighing cabinet control system opens the first shut-off valve 7 at the discharge end of the mixing tank 2, and puts all the evenly mixed grease into the storage tank 8. The pressure sensor 11 on the storage tank 8 records the total weight of the grease. The stirring device 9 on the oil storage tank 8 continuously stirs the oil stored in the tank to ensure the uniformity of the oil. According to different process requirements, the electric heater 12 heats the oil in the oil storage tank 8 to prevent the oil from solidifying and to meet the temperature requirements of feed production for oil. When feed production requires the addition of oil, the weighing cabinet control system controls the start and stop of the oil injection pump 13 motor 31 group to start the oil injection pump 13 and accurately spray the oil stored in the oil storage tank 8 to realize the post-oil injection operation. During the oil spraying process, the weighing cabinet control system calculates the amount of oil that has been delivered and the amount of oil remaining in the oil storage tank 8 by checking the weight data of the pressure sensor 11 in the oil storage tank 8 in real time, providing accurate data support for production.
