Description

Technical Field

[0001] This utility model relates to the field of organic fertilizer storage and fermentation technology, and more specifically, it relates to an organic fertilizer mixing and storage tank. Background Technology

[0002] In the field of organic fertilizer storage and fermentation, the fermentation of fertilizer in a sealed tank will continuously produce gases such as methane and carbon dioxide, which will cause the pressure inside the tank to rise. Existing storage tank pressure relief devices mostly use fixed threshold pressure relief valves or manual periodic venting. Fixed threshold pressure relief valves cannot adjust the pressure relief according to different fertilizer formulas and fermentation stages. Manual venting requires frequent inspections and is difficult to control the pressure accurately. At the same time, the existing adjustable pressure relief devices have a complicated adjustment process, requiring tools to disassemble parts and reset parameters. The adjustment efficiency is low, and the lack of an effective fixing structure after adjustment makes it easy for parameters to deviate in a vibration environment.

[0003] Regarding the structural reliability of pressure relief devices, existing adjustment mechanisms mostly use threaded advancement to change the spring preload. After long-term use, the threads are prone to wear, leading to a decrease in adjustment accuracy. The adjustment components lack an axial guide structure, which can easily cause skew and jamming during operation, affecting the smoothness of adjustment. After adjustment, they rely solely on threaded self-locking or a single fastener for fixation, lacking a reliable circumferential positioning and locking mechanism. Under tank vibration or external force, they are prone to loosening, causing changes in the pressure relief threshold and affecting storage safety and fermentation process stability.

[0006] The present invention is further configured such that a guide block is fixedly provided on the inner side of the adjusting sleeve, and a guide groove is provided on the outer wall of the outer sleeve. Multiple sets of the guide block and the guide groove are provided and slidably connected to ensure that the adjusting sleeve slides smoothly along the axial direction of the outer sleeve without deviation or jamming.

[0007] The present invention is further configured such that the multiple sets of movable blocks and the outer side of the arc groove are all arc-shaped and slidably connected, making the process of the arc groove pushing the movable blocks smoother and less strenuous.

[0008] The present invention is further configured such that push springs are connected between the multiple sets of positioning blocks and the outer wall of the positioning sleeve, so that the positioning blocks automatically extend outward and engage with the positioning holes to achieve self-locking.

[0009] The present invention is further configured such that the top surface of the multiple sets of positioning blocks and the inner side of the positioning holes are all arc-shaped, so as to facilitate the smooth sliding of the positioning blocks into the positioning holes to achieve quick engagement.

[0010] The present invention is further configured such that a support is fixedly provided on the top surface of the tank, a motor is fixedly provided on the top surface of the support, a rotating rod is fixedly provided at the output end of the motor, the rotating rod is rotatably connected to the tank, and a stirring rack is fixedly provided on the outer wall of the rotating rod. Multiple sets of stirring racks are provided to fully stir and mix the fertilizer in the tank to improve the uniformity of fermentation.

[0011] The present invention is further provided that the bottom surface of the tank is connected to a discharge pipe, which facilitates the discharge of fertilizer after the mixing and storage are completed.

[0012] The present invention is further provided that the top surface of the tank is connected to a feed pipe, which facilitates the addition of organic fertilizer raw materials into the tank.

[0013] (III) Beneficial Effects Compared with the prior art, the present invention provides an organic fertilizer mixing and storage tank, which has the following beneficial effects: 1. This utility model achieves automatic pressure relief by sliding a sealing block inside the outer sleeve on the top surface of the tank in conjunction with a pressure relief pipe. When the pressure of the fermentation gas inside the tank exceeds the preset elastic force of the pressure spring, the gas automatically pushes the sealing block upward and discharges excess gas from the gap between the outer sleeve and the pressure relief pipe. The sliding sleeve slides along the groove on the outer wall of the pressure relief pipe to guide the movement of the sealing block and ensure smooth movement. After the pressure decreases, the pressure spring automatically pushes the sealing block downward to reset and reseal. Automatic pressure regulation can be achieved without manual inspection and intervention, effectively solving the problems of poor adaptability and low efficiency of manual venting of traditional fixed threshold pressure relief valves.

[0014] 2. This utility model uses the rotating sleeve to push the movable block along the inner wall of the arc groove, causing the adjusting sleeve to slide along the outer sleeve axis. This changes the compression amount of the spring between the adjusting sleeve and the sliding sleeve, thereby adjusting the pressure threshold required for pressure relief. The guide block slides along the guide groove of the outer sleeve to guide the movement of the adjusting sleeve and prevent it from deviating or getting stuck. The arc-shaped design of the movable block and the outer side of the arc groove makes the pushing process smooth and effortless. Compared with the traditional screw-in adjustment method, it is more convenient to operate and avoids the decrease in accuracy caused by thread wear. The pressure relief parameters can be quickly adjusted according to the fermentation characteristics of different fertilizers.

[0015] 3. This utility model uses multiple sets of positioning blocks on the outer wall of the positioning sleeve to automatically extend outward under the action of a push spring and engage with the positioning holes of the fixing plate to perform circumferential positioning of the rotating sleeve. This effectively prevents the rotating sleeve from rotating under vibration, which would cause a change in the pressure relief threshold. The top surface of the positioning block and the inner side of the positioning hole are both set in an arc shape so that the positioning block can slide in smoothly to achieve quick engagement and positioning. When releasing the positioning, pressing the positioning block will cause it to retract into the positioning sleeve for easy readjustment. This forms a reliable self-locking positioning mechanism to ensure long-term stability of the adjustment parameters. Attached Figure Description

Multiple sets of positioning holes 15 abut against multiple sets of positioning blocks 13 respectively.

[0022] A bracket 19 is fixedly installed on the top surface of the tank body 1, a motor 20 is fixedly installed on the top surface of the bracket 19, a rotating rod 21 is fixedly installed at the output end of the motor 20, the rotating rod 21 is rotatably connected to the tank body 1, and a stirring rack 22 is fixedly installed on the outer wall of the rotating rod 21. Multiple sets of stirring racks 22 are provided.

[0023] A discharge pipe 23 is connected to the bottom surface of the tank body 1.

[0024] The top surface of tank 1 is connected to a feed pipe 24.

[0025] In this embodiment, organic fertilizer raw materials are added into the tank 1 through the feed pipe 24. The motor 20 drives the rotating rod 21 to drive multiple sets of stirring racks 22 to stir and mix the fertilizer in the tank 1. During the storage process, the fertilizer ferments and produces gas, causing the pressure inside the tank to gradually increase. When the pressure inside the tank exceeds the preset elastic force of the pressure spring 8, the gas pushes the sealing block 6 to slide upward along the outer sleeve 2. The sliding sleeve 5 slides along the sliding groove 4 on the outer wall of the pressure relief pipe 3 to guide the movement of the sealing block 6. After the sealing block 6 moves upward, the gas inside the tank is discharged from the gap between the outer sleeve 2 and the pressure relief pipe 3 to achieve automatic pressure relief. After the pressure decreases, the pressure spring 8 pushes the sliding sleeve 5 to drive the sealing block 6 to slide downward to reset and reseal the outer sleeve 2. After the stirring and storage are completed, the fertilizer is discharged through the discharge pipe 23.

[0026] Please see Figures 3-5 As a further implementation of the overall equipment: a guide block 16 is fixedly provided on the inner side of the adjusting sleeve 7, and a guide groove 17 is provided on the outer wall of the outer sleeve 2. Multiple sets of guide blocks 16 and guide grooves 17 are provided and slidably connected.

[0027] The outer sides of the multiple sets of movable blocks 11 and the arc-shaped groove 10 are all set to be arc-shaped and slidably connected.

[0028] Push springs 18 are provided between the multiple sets of positioning blocks 13 and the outer wall of the positioning sleeve 12.

[0029] The top surface of multiple positioning blocks 13 and the inner side of positioning holes 15 are all set to be arc-shaped.

[0030] More specifically, when the pressure relief threshold needs to be adjusted according to the different fertilizer fermentation characteristics, the rotating sleeve 9 is rotated. The inner wall of the arc groove 10 pushes the movable block 11, causing the adjusting sleeve 7 to slide along the outer sleeve 2 axially. The guide block 16 slides along the guide groove 17 to guide the movement of the adjusting sleeve 7 and prevent it from deviating. The arc-shaped design of the movable block 11 and the outer side of the arc groove 10 makes the sliding process smooth. The adjusting sleeve 7 moves up and down to change the compression of the compression spring 8 between it and the sliding sleeve 5, thereby adjusting the pressure threshold required for pressure relief. After the adjustment is in place, multiple sets of positioning blocks 13 extend outward under the action of the push spring 18 and are inserted into the positioning hole 15 of the fixing plate 14 to perform circumferential positioning of the rotating sleeve 9 to prevent it from rotating. The arc-shaped design of the top surface of the positioning block 13 and the inner side of the positioning hole 15 makes it easy for the positioning block 13 to be inserted smoothly and achieve rapid positioning.

[0031] In summary, during the use or operation of the overall equipment: organic fertilizer raw materials are added into the tank 1 through the feed pipe 24. The motor 20 drives the rotating rod 21 to drive multiple sets of stirring frames 22 to stir and mix the fertilizer in the tank 1. During the storage process, the fertilizer ferments and produces gas, causing the pressure inside the tank to gradually increase. When the pressure inside the tank exceeds the preset elastic force of the pressure spring 8, the gas pushes the sealing block 6 to slide upward along the outer sleeve 2. The sliding sleeve 5 slides along the sliding groove 4 on the outer wall of the pressure relief pipe 3 to guide the movement of the sealing block 6. After the sealing block 6 moves upward, the gas inside the tank is discharged from the gap between the outer sleeve 2 and the pressure relief pipe 3 to achieve automatic pressure relief. After the pressure decreases, the pressure spring 8 pushes the sliding sleeve 5 to drive the sealing block 6 to slide downward to reset and reseal the outer sleeve 2. After the stirring and storage are completed, the fertilizer is discharged through the discharge pipe 23.

[0032] When adjusting the pressure relief threshold according to the different fertilizer fermentation characteristics, the rotating sleeve 9 is rotated. The inner wall of the arc groove 10 pushes the movable block 11, causing the adjusting sleeve 7 to slide along the outer sleeve 2 axially. The guide block 16 slides along the guide groove 17 to guide the movement of the adjusting sleeve 7 and prevent it from deviating. The arc-shaped design of the movable block 11 and the outer side of the arc groove 10 makes the sliding process smooth. The adjusting sleeve 7 moves up and down to change the compression of the compression spring 8 between it and the sliding sleeve 5, thereby adjusting the pressure threshold required for pressure relief. After the adjustment is in place, multiple sets of positioning blocks 13 extend outward under the action of the push spring 18 and are inserted into the positioning hole 15 of the fixing plate 14 to perform circumferential positioning of the rotating sleeve 9 to prevent it from rotating. The arc-shaped design of the top surface of the positioning block 13 and the inner side of the positioning hole 15 makes it easy for the positioning block 13 to be inserted smoothly and achieve rapid positioning.
