Description

Technical Field

[0001] This utility model relates to the field of feed production and processing technology, specifically to a steam generator for feed production. Background Technology

[0002] Experiments have shown that feed pelleting increases the surface area of ​​the pellets, improves the digestibility of dry matter, protein, and energy, and facilitates nutrient absorption by animals. Steam generators used in feed processing are primarily used for heating and humidifying during pelleting. Steam exchanges heat with the materials in the conditioning drum, raising the temperature and cooking the feed. The high-quality steam system created by steam generators is a crucial measure to ensure safe and efficient production in feed mills. Aquatic feed steam generators are specialized equipment used in aquatic feed processing, primarily providing heating and humidification during pelleting. The steam generated by the generator exchanges heat with the feed ingredients in the conditioning drum, raising the feed temperature and cooking it. This process helps increase the surface area of ​​the feed pellets, improving the digestibility of dry matter, protein, and energy, thus facilitating nutrient absorption by aquatic animals. Aquatic feed steam generators create a high-quality steam system, making them one of the essential pieces of equipment for ensuring safe and efficient production in feed mills.

[0003] For example, the prior art, publication number CN217826678U, discloses a vertical feed steam generator, belonging to the field of feed production and processing. It includes a generator body, with a combustion chamber at the lower end, a steam chamber in the middle, and a reaction chamber at the upper end. A dustproof plate is installed inside the steam chamber, and support plates are symmetrically arranged at both ends of the generator body. Limiting blocks are symmetrically arranged at the upper and lower ends of both sides of the dustproof plate. This vertical feed steam generator has a removable dustproof plate inside the steam chamber, which effectively blocks smoke and dust from entering the reaction chamber and adhering to the feed surface, thus affecting the feed's quality, taste, and color. Simultaneously, the feed steam generator has a reaction box inside, which can be used to hold feed. The reaction box can be pulled out with its opening facing outwards, making it convenient to pour out the processed feed. It is simple to operate and convenient to use.

[0004] However, in the aforementioned prior art, feed processing is achieved by using steam generated from the combustion material in the combustion chamber. Although a dust filter is used to filter the smoke and impurities generated by the combustion steam, continuous combustion is required to ensure a continuous output of steam, which leads to excessive wear and tear on the dust filter. The dust filter needs to be replaced frequently to ensure the purity of the steam, resulting in high operating costs. Utility Model Content

[0005] The purpose of this invention is to provide a steam generator for feed production to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steam generator for feed production, comprising a reaction chamber and a steam generating assembly. The steam generating assembly is disposed on the side wall of the reaction chamber. The steam generating assembly includes a steam box, a steam chamber within which a steam chamber is formed. An electric heating rod is fixedly installed within the steam chamber. An installation groove is formed on the upper surface of the steam box, and a vacuum pump is fixedly installed within the installation groove. An extraction pipe is provided at the extraction end of the vacuum pump, and the other end of the extraction pipe is connected to the steam chamber. A guide hole communicating with the installation groove is formed on the side wall of the steam box. A pipe hole corresponding to the guide hole is formed on the side of the reaction chamber opposite to the steam box. An inner conveying pipe is disposed within the pipe hole, and the other end of the inner conveying pipe is fixedly connected to an outer conveying pipe within the reaction chamber. A gas distribution cylinder is fixedly installed in the inner wall of the reaction chamber. The end of the external conveying pipe opposite to the inner conveying pipe is connected to the gas distribution cylinder. A water injection pipe is inserted into the side wall of the steam box. Holes No. 1, No. 2, No. 3, and No. 4 are opened on the side wall of the reaction chamber. Limiting grooves are opened on both sides of the inner wall of holes No. 2, No. 3, and No. 4. A combustion frame, a dust-blocking filter plate, and a reaction frame are respectively installed in holes No. 2, No. 3, and No. 4. Limiting sliders matching the limiting grooves are set on both sides of the combustion frame, the dust-blocking filter plate, and the reaction frame. A wire mesh is set at the lower end of the inner wall of the reaction frame. A perforated plate is fixedly installed on the inner wall of the reaction chamber between the combustion frame and the dust-blocking filter plate. An exhaust hole is opened on the upper surface of the reaction chamber. An exhaust pipe is fixedly installed in the exhaust hole. Feed is placed in the reaction frame inside the reaction chamber, and water is injected into the evaporation chamber inside the steam chamber through the water injection pipe. Then, the electric heating rod is controlled to heat the water in the evaporation chamber to the boiling point and convert it into steam. Afterward, the vacuum pump in the installation slot transports the hot steam to the distribution cylinder through the guide hole, inner conveying pipe and outer conveying pipe. The distribution cylinder distributes the hot steam evenly in the reaction chamber and sprays it upward. Since the hot steam is generated by water reaching its boiling point, the steam is smokeless and relatively clean. While ensuring the processing effect of the feed, it reduces the wear of the dust filter screen due to smoke and impurities, effectively reducing the operating cost of steam filtration. When no water is available, the combustion material can be placed in the combustion frame, so that the reaction chamber can simultaneously carry out water steam processing and combustion steam processing, enabling the reaction chamber to have multiple processing modes for feed.

[0007] Preferably, the sidewalls of the combustion frame, dust filter plate, and reaction frame are slidably connected to the inner walls of holes No. 2, No. 3, and No. 4, respectively. By making the sidewalls of the combustion frame, dust filter plate, and reaction frame slidably connected to the inner walls of holes No. 2, No. 3, and No. 4, respectively, the combustion frame, dust filter plate, and reaction frame can be slidably removed along the inner walls of holes No. 2, No. 3, and No. 4, respectively.

[0008] Preferably, a door panel is connected to the hinge inside the first hole, and handles are fixedly installed on the side walls of the reaction frame, door panel, combustion frame, and dust filter plate. The door panel allows workers to disassemble and maintain the gas distribution cylinder from the reaction chamber, and the handles facilitate the removal of the reaction frame, combustion frame, dust filter plate, and opening of the door panel.

[0009] Preferably, multiple steam nozzles are fixedly inserted into the upper end face of the steam distribution cylinder, and a cleaning hole is provided on the upper end face of the steam box. The cleaning hole is connected to the steam chamber, and a cover plate is slidably installed inside the cleaning hole. By setting multiple steam nozzles, hot steam can be evenly sprayed upwards by multiple steam nozzles when it enters the steam distribution cylinder. The cover plate and the cleaning hole allow the interior of the steam box to be opened, allowing personnel to inspect and maintain the internal components and clean the inner wall of the steam box to ensure the purity of the water in the steam chamber.

[0010] Preferably, a temperature sensor and a liquid level sensor are fixedly installed on the inner wall of the steam tank, and a digital display central control module is fixedly installed on the side wall of the steam tank. Both the temperature sensor and the liquid level sensor are electrically connected to the digital display central control module. By setting up the temperature sensor and the liquid level sensor, the temperature sensor can monitor the steam temperature to control the heating temperature of the electric heating rod, and the liquid level sensor can monitor the remaining water in the steam tank to ensure normal steam generation. The digital display central control module can centrally display the data monitored by the temperature sensor and the liquid level sensor, facilitating the operator to control the heating temperature of the electric heating rod and replenish the water in the steam tank.

[0011] Preferably, an external power supply is provided outside the reaction chamber. The power supply terminal of the external power supply is electrically connected to the power terminals of the electric heating rod, vacuum pump, temperature sensor, liquid level sensor, and digital display central control module. By providing an external power supply, the electric heating rod, vacuum pump, temperature sensor, liquid level sensor, and digital display central control module can all be powered by the external power supply to ensure normal operation.

[0012] Preferably, the sidewalls of the plurality of limiting sliders are slidably connected to the inner walls of the matching limiting grooves. Magnets are provided at the front ends of the reaction frame, combustion frame, and dust filter plate, and the front ends of the reaction frame, combustion frame, and dust filter plate are magnetically connected to the inner wall of the reaction chamber via magnets. By slidably connecting the sidewalls of the plurality of limiting sliders to the inner walls of the matching limiting grooves, the plurality of limiting sliders can slide horizontally along the inner walls of the matching limiting grooves. Simultaneously, the magnets ensure that the front sidewalls of the reaction frame, combustion frame, and dust filter plate are magnetically attached to the inner wall of the reaction chamber when they enter the reaction chamber through the limiting sliders and limiting grooves on both sides, preventing the reaction frame, combustion frame, and dust filter plate from shifting out of the reaction chamber.

[0013] In summary, this application includes the following beneficial technical effects: This invention incorporates a steam generating assembly. After the feed is placed in the reaction chamber, water is injected into the steam chamber. An electric heating rod heats the water to its boiling point, converting it into hot steam. A vacuum pump then transports the hot steam through a guide hole, an inner conveying pipe, and an outer conveying pipe to a steam distribution cylinder. The steam distribution cylinder then sprays the hot steam upwards within the reaction chamber. Because the hot steam is generated from water reaching its boiling point, it is smokeless and relatively clean. This ensures the processing effect on the feed while reducing the wear and tear on the dust filter screen caused by smoke and impurities, effectively reducing the operating costs of steam filtration.

[0014] This invention incorporates a digital display central control module, a temperature sensor, and a liquid level sensor. The liquid level sensor monitors the remaining water level in the steam chamber, while the temperature sensor monitors the steam temperature inside the steam chamber. The digital display central control module can centrally display the data from both sensors, allowing staff to more intuitively observe the data inside the steam chamber and adjust the water level and temperature based on the monitored data.
