Description

Technical Field

[0001] This utility model relates to the field of low-temperature fermentation technology, specifically to a material crushing device for low-temperature fermentation. Background Technology

[0002] Corn stalks and cow dung are both common agricultural wastes, but they have different carbon-to-nitrogen ratios. Corn stalks are high in carbon, while cow dung is high in nitrogen. Mixing them can adjust the carbon-to-nitrogen ratio, which is beneficial for microbial activity. By properly controlling the ratio and fermentation conditions, low-temperature fermentation of corn stalks and cow dung can efficiently transform waste, achieving both ecological and economic benefits.

[0003] Low-temperature fermentation technology has been widely used in recent years. Low-temperature fermentation typically refers to the fermentation process at 15-30℃, primarily relying on the activity of mesophilic and pyrophilic microorganisms. Mixing corn stalks (high carbon) with cow manure (high nitrogen) and adjusting the carbon-to-nitrogen ratio (C / N) provides a suitable nutrient environment for microorganisms. Therefore, low-temperature fermentation has gradually become an important process. Its advantages lie in its ability to effectively inhibit the growth of certain harmful microorganisms while simultaneously increasing the yield and activity of certain target products. However, low-temperature fermentation places high demands on material processing, especially the pre-fermentation crushing process, which needs to ensure uniformity and appropriate particle size to facilitate microbial growth and metabolic activities.

[0004] Because existing material crushing devices cannot effectively control the equipment temperature during the crushing process, the heat generated cannot be dissipated in a timely manner. This temperature rise may adversely affect materials fermented at low temperatures. First, heat-sensitive components may degrade under high temperatures, leading to a decrease in the quality of fermentation raw materials and even affecting the growth and metabolism of microorganisms, thus reducing the fermentation effect. Second, excessively high temperatures may also damage the cellular structure of the crushed materials, affecting their particle uniformity and dispersibility, thereby affecting the utilization rate of materials by microorganisms during fermentation, and reducing the yield and quality of the final product. In addition, unstable equipment temperature may increase the risk of mechanical failure, such as accelerated wear of bearings, cutters, and other components due to overheating, thus shortening the service life of the equipment. Under long-term continuous operation, crushing devices lacking effective temperature control may also experience overheating, resulting in energy waste and reduced production efficiency.

[0005] Therefore, a material crushing device for low-temperature fermentation is proposed. Utility Model Content

[0006] The main objective of this invention is to provide a material crushing device for low-temperature fermentation, so as to overcome or improve at least one technical problem of the prior art, or to provide a useful alternative.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A material crushing device for low-temperature fermentation includes a base plate, a cooling component, and a crushing mechanism;

[0009] A collection box is fixedly connected to the top left side of the base plate, and a crushing cylinder is fixedly connected to the top of the base plate and above the collection box.

[0010] The cooling assembly includes a liquid storage tank, which is fixedly connected to the right side of the top of the base plate. Two sets of fixedly connected brackets are installed on both the left and right sides of the liquid storage tank's inner cavity, and each set of brackets has a filter screen attached to its inner cavity. A fixedly connected cooling rod is installed in the middle of the liquid storage tank's inner cavity. A fixedly connected first water pump is installed on the back side of the liquid storage tank, and the output end of the first water pump is connected to a cooling pipe that surrounds the surface of the pulverizing cylinder. A fixedly connected second water pump is installed on the top of the liquid storage tank, and the input end of the second water pump is connected to the end of the cooling pipe furthest from the first water pump.

[0011] The crushing mechanism includes a servo motor, which is fixedly connected to the middle of the top of the crushing cylinder.

[0012] Furthermore, the output end of the second water pump extends to the top of the inner cavity of the storage tank, and the input end of the first water pump extends to the bottom of the back side of the inner cavity of the storage tank. A guide plate is inclinedly provided at the bottom of the storage tank.

[0013] Furthermore, a collection box is placed at the bottom of the inner cavity of the collection box, and fixed connecting slots are installed on the bottom of the left and right sides of the inner wall of the collection box. Fixed connecting plates are installed on the left and right sides of the collection box, and the plates are engaged in the inner cavity of the collection box.

[0014] Furthermore, a vibration spring is fixedly connected to all four sides of the inner cavity of the collection box, a sieve box is fixedly connected to the top of the vibration spring, and a vibration motor is fixedly connected to the left side of the sieve box.

[0015] Furthermore, a feed pipe is connected to the left side of the top of the crushing cylinder, and a connecting pipe for material transfer is connected between the bottom of the crushing cylinder and the top of the collecting box.

[0016] Furthermore, a turntable is fixedly connected to the output end of the servo motor, and connecting rods are fixedly connected to both the left and right sides of the turntable. A guide block is fixedly connected to the bottom of the connecting rod, and a rotating rod is fixedly connected to the middle of the top of the guide block. Crushing blades are fixedly connected to both the connecting rod and the rotating rod.

[0017] Furthermore, a scraper is fixedly connected to the outer side of the connecting rod, and the outer side of the scraper contacts the inner wall of the crushing cylinder.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The first water pump draws in coolant from the storage tank by generating suction at its input end. The output end of the first water pump then transfers the coolant to a cooling pipe, which cools the grinding drum. Simultaneously, the second water pump draws in coolant from the cooling pipe at its input end. The output end of the second water pump returns the coolant to the storage tank, where it is filtered through a screen and then cooled a second time by a cooling rod. This cycle repeats continuously, maintaining the temperature inside the grinding drum. This effectively controls the heat generated during grinding, keeps the material temperature stable, prevents degradation of heat-sensitive components or reduction in microbial activity, ensures material quality and uniformity, improves fermentation efficiency, reduces equipment failure risks, extends equipment lifespan, and thus optimizes the overall production process.

[0020] By setting a mounting bracket, the filter screen can be disassembled for cleaning or replacement. By setting a guide plate, coolant can be prevented from accumulating in the inner cavity of the reservoir. The output end of the servo motor drives the turntable to rotate, the turntable drives the connecting rods on both sides to rotate, the connecting rods drive the guide block to rotate, the guide block drives the rotating rod to rotate, and the connecting rod and the rotating rod simultaneously drive the crushing blades on their surface to rotate, which can effectively improve the crushing effect and crushing efficiency of materials. By setting a scraper, materials can be prevented from adhering to the inner wall of the crushing cylinder.

[0021] By setting up a screening box, the crushed material can be collected. The vibration motor generates vibration and drives the screening box to vibrate. At the same time, the vibration spring increases the vibration amplitude of the screening box, which can screen the crushed material and the fine material. The fine material is screened into the inner cavity of the collection box for collection. By setting up slots and plates, the collection box can be easily fixed or disassembled.

The input end of the first water pump 403 extends to the bottom of the back side of the inner cavity of the storage tank 401. A guide plate 408 is inclinedly provided at the bottom of the storage tank 401.

After crushing, the material falls into the inner cavity of the screening box 11 through the connecting pipe. The vibration motor 12 generates vibration and drives the screening box 11 to vibrate.
