Description

Technical Field

[0001] This utility model relates to the field of circulating spraying technology, specifically to a fountain-type watering device. Background Technology

[0002] In the solid-state fermentation process for vinegar, the traditional method involves mixing raw materials such as wheat bran, koji, rice husks, and grain mash before loading them into a fermentation tank. A false bottom is installed in the tank to achieve solid-liquid separation. Liquid from the bottom of the tank is periodically pumped out and poured onto the surface of the upper material layer, allowing the sprayed liquid to penetrate to the bottom. This controls the temperature, oxygen concentration, and distribution of fermenting bacteria during fermentation to meet the process requirements of solid-state vinegar fermentation. After fermentation is complete, the raw vinegar is first extracted, then primary vinegar, secondary vinegar, and water are sprayed onto the surface of the material layer in sequence to displace the vinegar within the layer. Finally, a crane grab bucket is used to remove the vinegar residue, the fermentation tank is cleaned, and the next batch of production begins.

[0003] However, the existing process has significant technical defects: First, the pouring operation relies on manual operation of a rubber hose on the surface of the material layer, requiring operators to work continuously in a specific manner, which is labor-intensive and inefficient; Second, manual operation makes it difficult to accurately control the pouring force and range, resulting in poor pouring uniformity, high dispersion of fermentation data in different fermentation tanks, and difficulty in ensuring product quality stability; Third, if a self-rotating pouring device is used, it needs to be installed at the center of the top of the tank. During the feeding into the tank and discharging of the vinegar mash, the equipment needs to be moved frequently to avoid affecting the normal operation of the overhead grab bucket, which not only increases the complexity of operation but also easily leads to equipment damage and safety hazards. Utility Model Content

[0004] The purpose of this utility model is to provide a fountain-type spraying device. This device arranges the spraying components circumferentially along the inner side of the fermentation container opening, leaving a material inlet and outlet space at the center of the fermentation container. This ensures that the operation of the grab bucket is not affected during material inlet and outlet. At the same time, by controlling the components, the flow rate of each part flowing through the spraying components is different, realizing automatic circulation spraying of liquid material, significantly reducing labor intensity, reducing labor input, and saving production costs.

[0005] This utility model is achieved through the following technical solution:

[0006] A fountain-type watering device includes:

[0007] A spraying assembly is arranged circumferentially along the inner side of the fermentation container opening, and the nozzles connected to the spraying assembly spray liquid towards the center of the fermentation container.

[0008] The liquid supply assembly includes a main pipe and multiple branch pipes. One end of the main pipe is connected to the bottom of the fermentation vessel, and the other end of the main pipe is connected to all the branch pipes through a valve assembly. The other ends of the branch pipes are evenly distributed and connected to the spray assembly.

[0009] A control component, electrically connected to the valve assembly, causes the flow rate in the branch pipe to alternately decrease from high to low.

[0010] In this solution, the spraying assembly is arranged circumferentially along the inner side of the fermentation container opening. Together with nozzles that spray liquid towards the center of the container, the liquid can evenly cover the material surface. The liquid supply assembly draws liquid from the bottom of the fermentation container and delivers it to the spraying assembly. At the same time, the control assembly and valve assembly are electrically connected to allow the flow rate of the branch pipelines to change alternately, enabling the spraying assembly to achieve automatic circulating spraying similar to a fountain. This not only solves the problems of high labor intensity and poor uniformity of traditional manual watering, but also avoids affecting the grab bucket's feeding and discharging operations by leaving space in the center of the container. Ultimately, it achieves the effects of reducing labor intensity, reducing labor input, and saving production costs.

[0011] As a further embodiment of the watering device, the spraying assembly includes multiple independent main spray pipes, and the branch pipes are correspondingly matched and connected to one of the main spray pipes.

[0012] In this solution, by setting up multiple independent spray mains and matching and connecting them with corresponding branch pipes, the liquid supply to the spray mains in different areas can be controlled separately. When the fermentation situation in a certain area requires adjustment of the spray volume or spray frequency, it can be operated separately by controlling the valves on the corresponding branch pipes without affecting other areas, thus improving the accuracy and flexibility of watering. Furthermore, multiple independent spray mains can more meticulously cover the inside of the fermentation container, ensuring that the entire surface of the fermentation material is evenly watered.

[0013] As a further embodiment of the irrigation device, each of the branch pipes is connected to a pipe filter.

[0014] In this solution, during the solid-state vinegar fermentation process, although a false bottom is installed at the bottom of the fermentation tank, it is still difficult to prevent fibers and particulate matter from entering the liquid through the false bottom. If these impurities enter the spraying system with the liquid, they can easily clog the nozzles, affecting the normal spraying process and causing uneven spraying. This, in turn, affects the distribution of temperature, oxygen, and fermentation bacteria during fermentation, ultimately impacting the quality and yield of the vinegar. The pipeline filter effectively removes these fibers and particulate matter from the liquid, ensuring the purity of the liquid entering the main spray pipe and nozzles.

[0015] As a further embodiment of the irrigation device, each of the branch pipes is connected to a ball valve.

[0016] In this solution, since the spraying requirements vary at different stages of fermentation, the ball valve can be manually adjusted to flexibly adjust the flow rate and pressure of the liquid in the branch pipeline. By adjusting the opening of the ball valve, it can be ensured that the pressure of the nozzle is appropriate, so that the spraying distance of the spray liquid reaches the ideal state, such as just covering the center of the fermentation tank, while avoiding excessive pressure that causes the spray liquid to exceed the range of the fermentation tank, resulting in waste or environmental pollution.

[0017] As a further embodiment of the watering device, the nozzle is an omnidirectional, direct-projection, adjustable fountain nozzle.

[0018] In this solution, the omnidirectional adjustable fountain nozzle can be adjusted to create different spray patterns and ranges for the liquid material. Combined with the control components, this achieves an alternating spray effect similar to a fountain, simulating the dynamic process of natural spraying and ensuring that the fermentation material can fully contact the liquid at different locations.

[0019] As a further embodiment of the watering device, the spraying assembly includes a left spray main pipe and a right spray main pipe, and the branch pipes include a left branch pipe and a right branch pipe.

[0020] The left and right spray main pipes are laid sequentially along the inner circumference of the fermentation container opening, and the left and right spray main pipes are respectively connected to the left branch pipe and the right branch pipe.

[0021] In this solution, by controlling the liquid supply on the left and right sides respectively, the spray volume and spray time of different areas can be flexibly adjusted according to the fermentation requirements, thereby improving the accuracy of watering. Moreover, the design of the dual-sided spray main pipe helps to achieve an alternating spray mode similar to a fountain in conjunction with the control components, enhancing the dynamic effect of spraying and improving the contact effect between the liquid and the material.

[0022] As a further embodiment of the irrigation device, the valve assembly is an electric three-way valve, and the outlet of the electric three-way valve is connected to the left branch pipe and the right branch pipe respectively.

[0023] In this design, a control component allows the electric three-way valve to automatically adjust the opening of the two outlets, causing the liquid supply to the left and right branch pipes to alternate. For example, at one moment, the liquid supply to the left spray main is increased, causing the liquid ejected from the left nozzles to gradually extend in a parabolic trajectory from the tank edge towards the center, while simultaneously the liquid supply to the right spray main is reduced, causing the liquid ejected from the right nozzles to gradually recede from the tank center back to the tank edge; the next moment, the opposite occurs. This cycle repeats, creating a fountain-like spraying effect.

[0024] As a further embodiment of the irrigation device, the liquid supply component also includes a liquid supply pump, which performs work on the liquid in the main pipeline to draw the liquid from the bottom of the fermentation tank to the top for spraying.

[0025] As a further improvement to the watering device, the electric three-way valve is electrically connected to the control component to further optimize the spraying effect.

[0026] As a further embodiment of the watering device, the nozzle has a flat outlet.

[0027] In this design, the flat outlet allows the sprayed liquid to form a fan-shaped surface rather than a non-linear shape, greatly increasing the area covered by a single spray.

[0028] In summary, compared with the prior art, this utility model has the following main advantages and beneficial effects:

[0029] 1. This utility model arranges the spraying components circumferentially along the inner side of the fermentation container opening, leaving a space for material inlet and outlet in the center of the container. This avoids the trouble of frequent relocation during material inlet and outlet of traditional self-rotating spraying devices, making the grab bucket run smoothly, and making the operation of the feeding conveyor and the grab bucket grabbing operation more convenient and efficient. This reduces the complexity of operation, reduces equipment wear and safety hazards.

[0030] 2. This utility model, through the cooperation of control components and valve components, enables the flow rate through the branch pipeline to circulate alternately, allowing the liquid to uniformly cover the material surface in a fan shape, effectively solving the problem of poor uniformity in manual pouring.

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0039] Example 1

[0040] This embodiment 1 provides a fountain-type watering device, such as Figures 1-2 As shown, it includes a spray assembly, a liquid supply assembly, and a control assembly;

[0041] Please refer to Figure 2 As shown, the spray assembly includes multiple independent spray main pipes, and the liquid supply assembly includes a main pipe and multiple branch pipes. The multiple independent spray main pipes are arranged circumferentially along the inner side of the opening of the fermentation container 15, and each spray main pipe is connected to a branch pipe. The other end of all branch pipes is connected to the main pipe through a valve assembly, and the other end of the main pipe is connected to the bottom of the fermentation container 15.

[0042] Specifically, in this embodiment, the spray assembly includes a left spray main pipe 1 and a right spray main pipe 6. Both the left spray main pipe 1 and the right spray main pipe 6 are made of stainless steel. They are designed as semi-circular ring pipes (for circular tanks) or straight branch pipes (for square tanks) according to the shape of the fermentation container 15 (circular or square). The pipe diameter is slightly smaller than the diameter of the fermentation tank. They are fixed to the inner edge of the opening of the fermentation container 15, without occupying the central space of the tank, ensuring unobstructed loading and unloading of the crane grab bucket. The left spray main pipe 1 has mounting holes for fixing the left adjustable nozzle 2, and the right spray main pipe 6 has several mounting holes for fixing the right adjustable nozzle 7. All nozzles spray liquid towards the center of the fermentation container 15. Figures 3-4As shown, both the left adjustable nozzle 2 and the right adjustable nozzle 7 are omnidirectional direct-injection adjustable fountain nozzles. The omnidirectional direct-injection adjustable fountain nozzle consists of three parts: a fixed end, a spherical interface, and an adjusting end. One end of the fixed end is welded to the mounting hole of the main spray pipe, and the other end is connected to a large hollow sphere with an opening. One end of the adjusting end is welded to a small hollow sphere, and the other end is a flat liquid outlet. The spherical interface achieves 360° movement through the nesting of the large and small hollow spheres. Moving the adjusting end up and down can adjust the upward spray angle θ1 of the outlet, and moving the adjusting end left and right can adjust the spray angle θ2 of the outlet tilting to the left or right. After each nozzle is calibrated, the sprayed liquid will cover the entire material layer. This is existing technology and will not be described in detail.

[0043] At the same time, such as Figure 1 As shown, the above-mentioned branch pipelines include a left branch pipeline 5 and a right branch pipeline 10. The left spray main pipe 1 and the right spray main pipe 6 are connected to the left branch pipeline 5 and the right branch pipeline 10, respectively. A left pipeline filter 4 and a left ball valve 3 are installed on the left spray main pipe 1 in sequence. Similarly, a right pipeline filter 9 and a right ball valve 8 are installed on the right branch pipeline 10 in sequence. The pipeline filters intercept fibers and particles that may pass through the false bottom in the liquid to prevent nozzle blockage. The ball valves are used to manually adjust the branch flow rate to ensure that the spray liquid reaches the center of the pool at the farthest distance.

[0044] Please refer to the following: Figure 1 As shown, the liquid supply assembly includes a liquid supply pump 13, which is a pipeline centrifugal pump. The inlet is connected to the liquid outlet at the bottom of the fermentation container 15 through the main pipeline 14, and the outlet is connected to the valve assembly inlet through the pump outlet pipeline 12. The pump extracts and pressurizes the liquid at the bottom of the tank to provide power for spraying.

[0045] Here, the valve assembly is an electric three-way valve 11 with three ports (one inlet and two outlets). The outlets are connected to the left branch pipe 5 and the right branch pipe 10, respectively. The electric three-way valve 11 is connected to the control component via an electrical signal. When adjustment is required, the valve core is driven to rotate by the built-in micro motor of the electric three-way valve 11, thereby achieving alternating adjustment of the opening of the two outlets. When the left outlet gradually opens, the right outlet gradually closes simultaneously, and the pressure of the left branch increases, causing the spray liquid to extend from the edge of the pool to the center. Conversely, when the right outlet opens, the left outlet closes, and the spray liquid retreats from the center back to the edge of the pool, forming a fountain-like watering effect.

[0046] In some embodiments, the control component is a PLC control system, which is connected to the electric three-way valve 11 and the liquid supply pump 13 via electrical signals to achieve full-process automation.

[0047] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
