Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of biological enzyme preparation spraying devices, specifically to biological enzyme preparation spraying devices. Background Technology
[0002] Bioenzyme preparations are a class of proteins or RNA produced by living cells with catalytic functions. They can efficiently accelerate specific chemical reactions and play a crucial role in many fields such as industry, food, and medicine. Their core value lies in their high efficiency, specificity, and environmental friendliness, making them an important cornerstone of modern biotechnology applications. Using bioenzymes to treat pulping raw materials can significantly reduce pulping energy consumption and the amount of papermaking chemicals used. When using bioenzymes to pretreat pulping raw materials (such as wood chips, bamboo chips, and straw), the highly concentrated bioenzyme preparation needs to be diluted 1000-2000 times with water (one kilogram of bioenzyme preparation added to one to two tons of water) before being sprayed onto the pulping raw material pile.
[0003] A search revealed, for example, a Chinese patent application with publication number CN218291428U discloses a biological enzyme preparation spraying device. Through the configuration of a mixing pipe and movable wheels, the device can be moved on the ground, allowing it to be easily moved above the raw material pile. A flow control valve controls the water output from the storage tank, and an enzyme preparation delivery pump controls the material output from the storage tank. A three-way valve allows water and enzyme preparation to flow together into the mixing pipe. As the material flows, the spiral corrugations cause the water and enzyme preparation to tumble during the flow, ensuring thorough mixing and more efficient dilution. The diluted enzyme preparation is then sprayed onto the raw material pile through nozzles, making the biological enzyme treatment of the raw material pile more convenient and improving the efficiency of the treatment.
[0004] However, in actual use, mixing is achieved solely by the T-junction and the spiral corrugations of the mixing pipe. But if the flow rates of water and enzyme preparation fluctuate (such as instantaneous changes when adjusting the control valve / transfer pump), the initial ratio of the two at the T-junction is easily unbalanced. The mixing effect of the spiral corrugations is limited by the pipe length and flow rate, making it difficult to compensate for the initial ratio deviation. This may result in local enzyme concentrations that are too high or too low, affecting the spraying effect. Utility Model Content

By setting up an electromagnetic flow meter and a volumetric flow meter, the device ensures the stability of water and enzyme flow and guarantees the accuracy of enzyme concentration.

At the same time, during the enzyme injection process, some will enter the collection chamber, but will flow out from the through channel.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0024] This utility model provides, for example Figure 1-7 The biological enzyme preparation spraying device shown includes a storage tank 1, the interior of which is used to store raw materials.
[0025] In order to make the spraying mechanism 3 spray the raw materials more evenly, the outer wall of the storage box 1 is provided with a transmission mechanism 2 for moving on the top of the storage box 1.
[0026] like Figure 2-3 As shown, the transmission mechanism 2 includes two symmetrically arranged slide rails 21. The outer wall of the slide rail 21 is fixedly connected to the top of the outer wall of the storage box 1. A gearbox 24 is provided on the back of the slide rail 21. A sliding seat 23 is slidably connected inside the slide rail 21.
[0027] To move the sliding seat 23, a lead screw 22 is rotatably connected inside the slide rail 21 via bearings. One end of the lead screw 22 is fixedly sleeved with a synchronous pulley 25 inside the gearbox 24. The two synchronous pulleys 25 are connected by a synchronous belt. A first servo motor 26 is fixedly connected inside the gearbox 24. The output end of the first servo motor 26 is fixedly connected to one end of the lead screw 22. The two lead screws 22 have the same structure, and the first servo motor 26 is fixedly connected to one of the lead screws 22. When the first servo motor 26 rotates, it will rotate the lead screw 22 connected to it. The rotation of the lead screw 22 will cause the synchronous pulley 25 sleeved on its surface to rotate. The rotation of the synchronous pulley 25 will cause the other synchronous pulley 25 to rotate through the synchronous belt. The rotation of the other synchronous pulley 25 will cause the other lead screw 22 to rotate. Thus, the rotation of the first servo motor 26 drives the rotation of the two lead screws 22, thereby driving the movement of the sliding seat 23.
[0028] The first servo motor 26 enables the lead screw 22 to rotate in both directions. In order to spray the raw materials more evenly, the sliding seat 23 needs to move back and forth.
[0029] In order to spray the raw materials evenly, a spraying mechanism 3 is provided on the top of the sliding seat 23 for spraying the raw materials inside the storage box 1.
[0030] like Figure 4 As shown, the spraying mechanism 3 includes a mixing tank 305, inside which a stirring assembly 306 is provided. A connecting water pipe 303 and a connecting medicine pipe 304 are fixedly connected to the top two sides of the mixing tank 305, respectively. A water storage tank 301 and a medicine storage tank 302 are fixedly connected to one end of the connecting water pipe 303 and the connecting medicine pipe 304, respectively. The bottom of the mixing tank 305, the water storage tank 301, and the medicine storage tank 302 are fixedly connected to the top of the sliding seat 23.
[0031] In order to extract water located inside water tank 301 and enzymes located inside drug storage tank 302, such as Figure 4 As shown, an electromagnetic flow meter 307 and a water pump 308 are sequentially fixedly connected to the surface of the water pipe 303. The water pump 308 is fixedly connected to the top of the mixing tank 305, and the electromagnetic flow meter 307 is located outside the water pump 308. An enzyme preparation delivery pump 309 and a volumetric flow meter 310 are sequentially fixedly connected to the surface of the medicine pipe 304. The enzyme preparation delivery pump 309 is fixedly connected to the top of the mixing tank 305, and the volumetric flow meter 310 is located outside the water pump 308. When extraction is required, the operator starts the water pump 308 and the enzyme preparation delivery pump 309. The water inside the water storage tank 301 and the enzyme inside the medicine storage tank 302 will be injected into the mixing tank 305 through the water pipe 303 and the medicine pipe 304, respectively.
[0032] Meanwhile, the electromagnetic flowmeter 307 can accurately measure the real-time water flow rate. Considering the viscosity of the enzyme, a volumetric flowmeter 310 is installed on the surface of the connecting tube 304. This is suitable for the above environment and can accurately measure the real-time enzyme flow rate. Staff can accurately determine the water-to-enzyme ratio based on experience, ensuring a stable concentration of the mixture.
[0033] It should be noted that both water pump 308 and enzyme preparation delivery pump 309 are variable frequency pumps, which can automatically adjust the flow rate and pressure according to different working conditions.
[0034] In order to spray the raw materials, such as Figure 4As shown, a water outlet pipe 312 is fixedly connected to the bottom center of the mixing tank 305. The bottom end of the water outlet pipe 312 is connected to a spray box 313 via a flange. A filter screen is snapped onto the surface of the water outlet pipe 312 to filter impurities in the mixture and prevent clogging of the spray nozzles 314. At the same time, the flange connection allows the spray box 313 to be easily removed, and the filter screen to be easily removed for cleaning. Multiple spray nozzles 314 are fixedly connected to the surface of the spray box 313. The spray nozzles 314 are fan-shaped nozzles (spray angle of 60°). By superimposing the spray angles of the nozzles, the coverage area is expanded by 2 times, so that the surface of the raw material pile can be sprayed.
[0035] To ensure a stable spray flow rate, such as Figure 4 As shown, a diaphragm-type pressure regulating valve 311 is fixedly sleeved on the surface of the water outlet pipe 312 to reduce pressure attenuation caused by liquid level drop and control the initial pressure fluctuation within ±5%. During the reciprocating movement of the sliding seat 23, the diaphragm-type pressure regulating valve 311 is opened, and the mixed liquid inside the mixing tank 305 flows from the water outlet pipe 312 into the spraying tank 313 and is finally sprayed out from the nozzle 314.
[0036] In order to mix the water and enzymes located inside the mixing tank 305, such as Figure 5 As shown, the stirring assembly 306 includes a second servo motor 3061, which is fixedly connected to the top of the mixing chamber 305. The output end of the second servo motor 3061 is fixedly connected to a stirring shaft 3062. The surface of the stirring shaft 3062 is provided with multiple stirring blades 3063. A notch 3064 is opened at the top center of the stirring blades 3063. A collection chamber 3065 is provided at the bottom of the notch 3064. Multiple through grooves 3066 are opened on the outer wall of the collection chamber 3065. A blockage 3067 is provided inside the through grooves 3066. During the rotation of the second servo motor 3061, the stirring shaft 3062 will be rotated. The rotation of the stirring shaft 3062 will rotate the stirring blades 3063, thereby stirring the inside of the mixing chamber 305. The mixing chamber 305 is made of tempered glass, which makes it convenient for the staff to observe the flow path.
[0037] To remind staff whether the enzyme addition rate is accurate, such as Figure 7As shown, the plugging component 3067 includes a fixed shaft 30672, which is fixed to the surface of the notch 3064. A plugging plate 30671 is sleeved on the surface of the fixed shaft 30672. The top and bottom of the plugging plate 30671 are symmetrically provided with movable grooves 30673. The thickness of the plugging plate 30671 is adapted to the height of the through groove 3066. The movable grooves 30673 are located at the top and bottom of both sides of the through groove 3066. Meanwhile, the size of the notch 3064 is adapted to the outlet of the connecting tube 304. The size of the inlet is matched, so it can be ensured that the small amount of enzyme added will enter the collection chamber 3065. During the stirring process of the stirring plate 3063, the enzyme will pass through the moving tank 30673 and finally flow out from the through tank 3066, thus forming a flow path. If the enzyme flows in too fast, a large amount of enzyme will form a flow path, making the flow path obvious enough. The staff can know the rate of enzyme addition by checking whether the flow path is obvious. If the rate is too fast, the enzyme preparation delivery pump 309 needs to be properly maintained.
[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
