[0021] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0022] See also Figure 1 to Figure 2 As shown, a liquid methionine spraying device is used to spray liquid raw materials (including but not limited to: liquid methionine, acidulant, mildew inhibitor, liquid choline, etc.) into the inside of a mixer (not shown in the figure). The liquid methionine spraying device includes a frame 1, a ton barrel 2, a weighing hopper 3, a nozzle assembly 4, a plurality of nozzle assemblies 5, an air blowing assembly 6 and a controller 7. The frame 1 is fixed on the ground, the ton barrel 2 is fixed on the top of the frame 1, and the ton barrel 2 is used to hold liquid raw materials. The weighing hopper 3 is fixed inside the frame 1, and the input end of the weighing hopper 3 is connected to the output end of the ton barrel 2 through a pipeline 9. A first angle seat valve 31 is provided on the pipeline 9 between the weighing hopper 3 and the ton barrel 2. The first angle seat valve 31 is used to open or close the transmission channel between the weighing hopper 3 and the ton barrel 2.

[0023] The weighing hopper 3 is used to quantitatively weigh the liquid raw material in the mixer. In this embodiment, a plurality of weighing sensors 32 are fixedly arranged on the side wall of the weighing hopper 3, and the plurality of weighing sensors 32 are evenly arranged along the circumference of the weighing hopper 3. A plurality of suspension rods 33 are vertically fixedly arranged on the top wall of the frame 1, and the plurality of suspension rods 33 correspond to the plurality of weighing sensors 32 one by one, and are fixedly connected to the top of the weighing sensors 32, that is, the weighing hopper 3 is suspended inside the frame 1 through the weighing sensors 32 and the suspension rods 33.

[0024] Since the amount of liquid raw material output to the mixer each time is generally small, by setting the ton barrel 2 at the top of the frame 1, even if the ton barrel 2 is set above the weighing hopper 3, the liquid raw material can flow into the weighing hopper by gravity, and no additional liquid pump is needed to reduce enterprise costs. Preferably, a manual valve 21 is provided at the output end of the ton barrel 2. When the equipment is not started, the manual valve 21 can be closed to avoid accidental damage to the pipeline 9 during use, resulting in loss caused by the outflow of liquid raw materials. When the equipment needs to be started, the staff needs to open the manual valve 21 in advance.

[0025] In this embodiment, a diaphragm pump 8 is provided on one side of the frame 1, and the output end of the diaphragm pump 8 is connected to the inside of the ton barrel 2, so as to transport the bulk liquid raw materials to the ton barrel 2 for storage. Preferably, a high liquid level switch and a low liquid level switch (not shown in the figure) are provided in the ton barrel 2, wherein the high liquid level switch, the low liquid level switch and the diaphragm pump 8 are electrically connected to the controller 7 respectively. During implementation, the diaphragm pump 8 is started to pump the bulk liquid raw materials into the inside of the ton barrel 2. When the top surface of the liquid raw materials in the ton barrel 2 reaches the sensing height of the high liquid level switch, the controller 7 controls the diaphragm pump 8 to stop. When the top surface of the liquid raw materials in the ton barrel 2 is at the sensing height of the low liquid level switch, an alarm is sent to the controller 7 to prompt the staff to add liquid raw materials to the ton barrel 2, thereby facilitating the staff to monitor the stock of the liquid raw materials in the ton barrel 2. Preferably, the outer side of the ton barrel 2 is coated with an insulation layer to ensure that the liquid methionine has good fluidity.

[0026] One end of the nozzle assembly 4 is fixed inside the frame 1, the input end of the nozzle assembly 4 is connected to the output end of the weighing hopper 3, and the output end of the nozzle assembly 4 extends toward the mixer, and is used to provide liquid raw materials of a predetermined pressure to the inside of the mixer. In this embodiment, the nozzle assembly 4 includes a vane pump 41 and a plurality of connectors 44, wherein the vane pump 41 is fixed to the bottom surface inside the frame 1, the input end of the vane pump 41 is connected to the output end of the weighing hopper 3, the plurality of connectors 44 are arranged on the outside of the mixer, and the output end of the vane pump 41 is connected to the plurality of connectors 44 through a pipeline 9.

[0027] In this embodiment, a steel wire hose 34 is fixedly provided at the output end of the weighing hopper 3, and the input end of the vane pump 41 is connected to the steel wire hose 34. Since the weighing hopper 3 is suspended inside the frame 1, a soft connection between the vane pump 41 and the weighing hopper 3 can be achieved through the steel wire hose 34, thereby avoiding deviations in the weighing data of the weighing hopper 3 due to vibration of the vane pump 41.

[0028] Preferably, a pressure regulating valve 42 is provided between the input end and the output end of the vane pump 41 to control the flow rate and pressure of the liquid raw material, thereby maintaining the stability of the output pressure, wherein the pressure regulating valve 42 has a dial, which is convenient for the staff to manually adjust to the preset pressure position; preferably, an electronic pressure transmitter 43 is also provided between the vane pump 41 and the plurality of connectors 44, which is convenient for real-time monitoring of the output pressure of the vane pump 41. In this embodiment, a filter 45 is also provided between the vane pump 41 and the weighing hopper 3, which is used to filter impurities in the liquid raw material to prevent the impurities in the liquid raw material from damaging the vane pump 41. Furthermore, a second angle seat valve 46 is also provided between the input end of the vane pump 41 and the filter 45, which is used to open or close the transmission channel between the vane pump 41 and the weighing hopper 3.

[0029] A plurality of spray head assemblies 5 are fixedly arranged inside the mixer and are used to uniformly spray the liquid raw material into the mixer. A plurality of connectors 44 are respectively connected to the plurality of spray head assemblies 5 through pipelines 9. In this embodiment, each spray head assembly 5 includes a liquid inlet end 51, an air inlet end 52, and a nozzle 53 arranged between the liquid inlet end 51 and the air inlet end 52. A plurality of connectors 44 are respectively connected to each liquid inlet end 51 through pipelines 9. Preferably, a third angle seat valve 55 is further provided between the plurality of connectors 44 and the vane pump 41, which is used to open or close the transmission channel between the plurality of connectors 44 and the vane pump 41.

[0030] The air blowing assembly 6 is fixedly mounted on one side of the frame 1. The output end of the air blowing assembly 6 is connected to the air inlet end 52 to provide compressed air for the nozzle assembly 5. During implementation, the air blowing assembly 6 can output compressed air to the inside of the nozzle assembly 5, and the compressed air is mixed with the liquid raw material output from the liquid inlet end 51 and then sprayed into the mixer through the nozzle 53. It is to avoid that the liquid raw material is retained at the nozzle 53 or drips at the nozzle 53 due to the low pressure of the liquid raw material output from the liquid inlet end 51, and the direct contact between the drop-shaped liquid raw material and the material may cause the material to agglomerate, resulting in uneven stirring and affecting the production quality. Preferably, a gas check valve 54 is provided between the nozzle 53 and the air inlet end 52 to prevent the liquid raw material from flowing into the air blowing assembly 6. Preferably, the input end of the air blowing assembly 6 is connected to a fourth angle seat valve 61.

[0031] The controller 7 is electrically connected to the mixer, the nozzle assembly 4, the air blowing assembly 6 and the first angle seat valve 31, the second angle seat valve 46, the third angle seat valve 55, and the fourth angle seat valve 61, respectively. The controller 7 includes a frequency converter for adjusting the pressure of the nozzle assembly 4. The pipeline 9 between the ton barrel 2, the weighing hopper 3, and the nozzle assembly 4 can be separated by setting the first angle seat valve 31, the second angle seat valve 46, the third angle seat valve 55, and the fourth angle seat valve 61. When the corresponding pipeline 9 needs to be repaired, it is only necessary to close the corresponding first angle seat valve 31, the second angle seat valve 46, the third angle seat valve 55 or the fourth angle seat valve 61, so as to facilitate the staff to maintain the equipment.

[0032] It should be noted that the pipelines 9 of the present invention are connected by the chuck-type joints 91 of the prior art. The chuck-type joints 91 can be used to quickly connect the pipelines 9 and are easy to disassemble, thus shortening the production and maintenance time.

[0033] When the liquid methionine spraying device of the utility model is implemented, the diaphragm pump 8 is started to transport the bulk liquid raw material to the ton barrel 2 for storage. When a preset amount of liquid raw material is needed, the staff opens the manual valve 21, and the controller 7 starts the first angle seat valve 31, so that the liquid raw material can flow into the weighing hopper 3 by gravity. At the same time, the weighing hopper 3 weighs the liquid raw material through the weighing sensor 32.

[0034] In one embodiment of the utility model, the weighing hopper 3 adopts a weighing mode. When it is implemented, the first angle seat valve 31 is opened, and the liquid raw material in the ton barrel 2 flows into the weighing hopper 3 by gravity, and the weighing sensor 32 is weighed at the same time. When the liquid raw material in the weighing hopper 3 reaches a preset weight, the first angle seat valve 31 is closed, and the liquid raw material in the ton barrel 2 is no longer discharged into the weighing hopper 3. When it is necessary to spray the liquid raw material into the mixer, it is only necessary to empty the liquid raw material in the weighing hopper 3. When the value of the weighing hopper returns to zero, it means that the liquid spraying is completed.

[0035] In another embodiment of the present invention, the weighing hopper 3 adopts a weight reduction mode. When the mode is implemented, the first angle seat valve 31 is opened, and the liquid raw material in the ton barrel 2 flows into the weighing hopper 3 by gravity, until the weighing hopper 3 is filled with liquid raw materials and the first angle seat valve 31 is closed. When it is necessary to spray liquid raw materials into the mixer, the vane pump 41 is turned on, and the vane pump 41 extracts the liquid raw materials in the weighing hopper. At the same time, the weighing sensor 32 weighs the liquid raw materials in the hopper 3 in real time, and feeds the data back to the controller 7 in real time. When the total weight of the liquid raw materials in the weighing hopper reaches the preset value, that is, when the delivery amount of the liquid raw materials is completed, the controller 7 turns off the vane pump 41. In short, the weighing mode is to weigh a predetermined amount of liquid raw materials each time; and the weight reduction mode is to discharge only a predetermined amount of liquid raw materials each time.

[0036] The vane pump 41 adjusts the output pressure of the liquid raw material through the pressure regulating valve 42, and the vane pump 41 outputs the liquid raw material to the nozzle assembly 4 and the nozzle assembly 5 in sequence, and sprays the liquid raw material into the mixer through the nozzle 53 of the nozzle assembly 5, so that the liquid raw material is fully mixed with the material inside the mixer. When the liquid raw material is sprayed or is about to be sprayed, the air blowing assembly 6 is started, and the compressed air enters the air inlet and the nozzle 53 in sequence to discharge the remaining liquid raw material or the liquid remaining in the nozzle 53.

[0037] The air blowing component 6 is used to ensure that a predetermined amount of liquid raw material is fully discharged into the mixer, thereby preventing part of the liquid raw material from remaining in the nozzle component 5, resulting in inaccurate raw material addition. In addition, the compressed air of the air blowing component 6 allows the liquid raw material remaining in the nozzle 53 to be sprayed into the mixer with a certain pressure, thereby preventing dripping at the nozzle 53 and causing uneven mixing.

[0038] The liquid methionine spraying device of the utility model is highly integrated. By arranging the controller 7, the vane pump 41, the weighing hopper 3, and the ton barrel 2 inside and outside the frame 1, the space occupied is small, and the neatness and aesthetics of the equipment are increased. Preferably, a protective cover (not shown in the figure) is also provided on the outside of the frame 1, and the dustproof effect can be improved by the protective cover. By adopting the weighing type or the weight loss type to add the liquid raw material, the accuracy of the liquid raw material can be controlled within an error of 10-20 grams per batch.

[0039] The above description is only a preferred embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
