Description

Technical Field

[0001] The invention relates to the technical field of fermentation tanks, and in particular to a fermentation tank that is convenient for detection. Background Art

[0002] With the increasing depletion of fossil energy, biomass energy represented by straw waste has been widely favored due to its renewable and environmentally friendly advantages. The annual crop straw waste is about 600 million tons. The rational and effective use of straw is of great significance to the construction of a conservation-oriented society. Straw is the general name for the stems, leaves and spikes of mature crops. Straw fertilizer is rich in organic matter, with relatively balanced nitrogen, phosphorus and potassium nutrients. It also contains various trace elements. It is a common fertilizer suitable for various crops and various soils, and has a significant effect of improving product quality and increasing output. The production of straw organic fertilizer requires the fermentation of straw materials. Organic fertilizers need to be aerobically fermented to be made into fertilizers. The fermentation tank is the place where organic fertilizers are fermented. The fermentation tank provides a relatively closed environment for the fermentation of organic fertilizers.

[0003] For example, the patent with the announcement number CN 21773299 U discloses a new type of compost fermentation tank, including a fermentation tank body, a motor is fixedly installed at the top of the fermentation tank body, a stirring rod is installed at the output end of the motor, a feed pipe is connected to the top of the fermentation tank body, a discharge pipe is connected to the bottom of the fermentation tank body, a pressure gauge is fixedly installed at the top of the fermentation tank body, and a sliding groove is provided on the top surface of the fermentation tank body near the pressure gauge. However, it still has the following problems: during the fermentation process, the gas in the tube cannot be sealed and tested. When testing, the tank body needs to be opened, which easily leads to the entry of external air, affecting the fermentation environment in the tube and causing inaccurate test results. Summary of the invention

[0004] In order to solve the above problems in the prior art, a fermentation tank that is convenient for detection is provided.

[0005] The technical solution adopted by the present invention to solve its technical problem is: The present invention proposes a fermentation tank that is convenient for detection, including a tank body, wherein the tank body is provided with a detection port, the detection port is slidably connected to a detection tube, and the detection tube is slidably connected to a floating plate that can float on the material; an air suction box is arranged in the detection tube, and the air suction box is provided with an air intake pipe that is in a blocked state in an initial state; when the floating plate contacts the material and the detection tube continues to descend, the air intake pipe can be opened.

[0006] Preferably, a sealing ball is arranged in the air inlet pipe, and the air inlet pipe includes an air inlet cavity and a blocking cavity, and the air inlet cavity is located above the blocking cavity.

[0007] Preferably, the suction box is slidably connected to a push rod, the push rod is located directly below the sealing ball, the push rod is connected to the suction box via a compression spring, and the lower end of the push rod passes through the suction box.

[0008] Preferably, when the sealing ball is located in the blocking cavity, the sealing ball blocks the air inlet pipe. When the sealing ball moves into the air inlet cavity, a gap is left between the sealing ball and the air inlet cavity for gas to pass through. The gravity of the air suction box is greater than the elastic force of the compression spring.

[0009] Preferably, the suction box is provided with a slot, the detection tube is slidably connected with a limit pin which can slide into the slot, the limit pin is connected with a pull rope, and the other end of the pull rope is connected to the floating plate.

[0010] Preferably, the floating plate is fixedly connected to a support rod, and the support rod is rotatably connected to a guide wheel, and the guide wheel is located between a connection point between the pull rope and the limit pin and a connection point between the pull rope and the floating plate.

[0011] Preferably, the detection tube is provided with an air inlet hole, and a sealing plug is slidably connected in the air inlet hole to block the air inlet hole in an initial state, and the sealing plug is fixedly connected to a limit pin.

[0012] Preferably, the air intake pipe is slidably connected with a blocking plate, the limit pin is connected to the detection tube via a spring, and the blocking plate is located on one side of the limit pin.

[0013] Preferably, the air intake pipe is slidably connected with a baffle, the baffle is fixedly connected with a pull rod, the limit pin is provided with a pull groove for the pull rod to slide into, and the limit pin is connected to the detection tube via a tension spring.

[0014] Preferably, a piston is slidably connected in the detection port, the piston and the detection tube are fixedly connected, the piston is provided with an exhaust hole, and a one-way valve is arranged in the exhaust hole; a sealing plate is slidably connected to the bottom end of the detection port, and a vertical rod is rotatably connected to the tank body, and the vertical rod can drive the sealing plate to move, thereby opening the lower end of the detection port.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present application is provided with a detection port. In the initial state, the piston and the sealing plate make the detection port in a closed state. At this time, the detection tube is located in the detection port, and the detection port can be evacuated through the suction hole, so that the excess air in the detection port is sucked away, thereby preventing the gas in the fermentation tank from mixing with the gas in the detection port during the subsequent detection process, which affects the efficiency and quality of the detection. The operation is convenient. During the fermentation process, the fermentation state in the fermentation tank can be detected at any time, so as to monitor the fermentation process in real time, which is conducive to the fermentation work.

[0016] 2. The present application is provided with an air suction box, which is located in the detection tube. After the float plate contacts the material, as the detection tube continues to descend, the pull rope hung on the guide wheel can move the limit pin out of the slot, and the air suction box can fall into the detection tube. After the push rod contacts the bottom of the detection tube, the push rod can lift the sealing ball upward, and the air inlet pipe opens. At the same time, the limit pin drives the air inlet hole to open, allowing the gas above the material to enter, thereby realizing the collection of the gas above the material. The subsequent analysis of the gas composition is convenient for real-time monitoring of the fermentation process.

[0017] 3. The present application is provided with a blocking plate. When the detection tube is pulled out, the pull rope returns to its original length, and the spring drives the limit pin to reset. At this time, under the elastic force of the spring, the limit pin can continue to move a greater distance, which can just move the blocking plate to make the air inlet pipe in a blocked state, thereby allowing the air suction box to re-form a sealed space to prevent the entry of external gas, thereby realizing automatic sealing of the air suction box after suction, and facilitating subsequent detection work.

DETAILED DESCRIPTION

[0020] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0021] Embodiment 1 like Figure 1-Figure 5 As shown, this embodiment proposes a fermentation tank that is convenient for detection, including a tank body 1, the tank body 1 is provided with a detection port 2, the detection port 2 is slidably connected to a detection tube 7, the detection tube 7 is fixedly connected to a handle 3, the detection tube 7 is slidably connected to a floating plate 8 that can float on the material 10, the detection tube 7 is fixedly connected to a limit block for limiting the floating plate 8, the floating plate 8 is located above the limit block, and the floating plate 8 can only move above the limit block, thereby preventing the floating plate 8 from detaching from the detection tube 7.

[0022] The bottom end of the detection tube 7 is a conical head. When the detection tube 7 descends, it can drive the floating plate 8 to descend at the same time. The floating plate 8 is elliptical in shape. When the size of the floating plate 8 is suitable, when the detection tube 7 drives the floating plate 8 to descend and encounters the material 10, the floating plate 8 can be suspended on the material 10 and cannot descend, while the detection tube 7 continues to descend under the action of the conical head and penetrates into the material 10.

[0023] An air suction box 18 is arranged in the detection tube 7. The air suction box 18 has an air inlet pipe 12 which is in a blocked state in the initial state. When the floating plate 8 and the material 10 are in contact and the detection tube 7 continues to descend, the air inlet pipe 12 can be opened. In the initial state, there is a certain gap between the air suction box 18 and the bottom end of the detection tube 7.

[0024] A sealing ball 13 is arranged in the air inlet pipe 12. The air inlet pipe 12 includes an air inlet cavity 27 and a blocking cavity. The air inlet cavity 27 is located above the blocking cavity. The sealing ball 13 is connected to the air inlet pipe 12 through a return spring. The width of the air inlet cavity 27 is greater than the diameter of the sealing ball 13, while the width of the blocking cavity is less than the diameter of the sealing ball 13.

[0025] The air suction box 18 is slidably connected with a push rod 19, which is located directly below the sealing ball 13. The push rod 19 is connected to the air suction box 18 through a compression spring 20. The lower end of the push rod 19 passes through the air suction box 18. The compression spring 20 is sleeved on the push rod 19. The compression spring 20 is located outside the air suction box 18. The upper end of the compression spring 20 is connected to the air suction box 18, and the lower end of the compression spring 20 is connected to the push rod 19.

[0026] In the initial state, under the action of the return spring, the sealing ball 13 is located in the blocking cavity. When the sealing ball 13 is located in the blocking cavity, the sealing ball 13 puts the air inlet pipe 12 in a blocked state. When the push rod 19 is pushed upward to move the sealing ball 13 into the air inlet cavity 27, a gap is left between the sealing ball 13 and the air inlet cavity 27 for gas to pass through.

[0027] The gravity of the air suction box 18 is greater than the elastic force of the compression spring 20. Therefore, when the limit on the air suction box 18 is released, the air suction box 18 performs free fall motion under the action of gravity, the air suction box 18 descends, and the push rod 19 contacts the bottom end of the detection tube 7. At this time, the push rod 19 cannot continue to move, and the air suction box 18 continues to descend. Finally, the push rod 19 can push the sealing ball 13 into the air intake cavity 27, which is convenient for the air suction box 18 to intake air.

[0028] The suction box 18 is provided with a slot, and both ends of the detection tube 7 are slidably connected with a limit pin 14 that can slide into the slot. The limit pin 14 is connected to a pull rope 17, and the other end of the pull rope 17 is connected to the floating plate 8. In the initial state, the limit pin 14 slides into the slot, and the suction box 18 is supported at this time. There is a certain gap between the suction box 18 and the bottom end of the detection tube 7, and the pull rope 17 is in a relaxed state at this time.

[0029] The floating plate 8 is fixedly connected to a support rod, and the support rod is rotatably connected to a guide wheel 16. The guide wheel 16 is located between the connection point of the pull rope 17 and the limit pin 14 and the connection point of the pull rope 17 and the floating plate 8. The pull rope 17 can be hung on the guide wheel 16. When the floating plate 8 cannot continue to move, the detection tube 7 continues to descend. The pull rope 17 is non-retractable, so the pull rope 17 can pull the limit pin 14 out.

[0030] The detection tube 7 is provided with an air inlet hole 26, in which a sealing plug 21 is slidably connected, which blocks the air inlet hole 26 in an initial state. The sealing plug 21 and the limit pin 14 are fixedly connected. In the initial state, the sealing plug 21 blocks the air inlet hole 26, and a relatively closed space is formed in the detection tube 7. When the limit pin 14 is pulled out, the sealing plug 21 can be pulled out at the same time, and the air inlet hole 26 is opened.

[0031] The air intake pipe 12 is slidably connected with a blocking plate 11, a limit pin 14 is connected to the detection tube 7 through a spring 15, the blocking plate 11 is located on one side of the limit pin 14, the spring 15 is sleeved on the limit pin 14, one end of the spring 15 is connected to the limit pin 14, and the other end of the spring 15 is connected to the detection tube 7. In the initial state, under the elastic force of the spring 15, the limit pin 14 is located in the slot, and the blocking plate 11 does not block the air intake pipe 12.

[0032] The blocking plate 11 is of L-shaped design. When the air suction box 9 drives the limit pin 14 to rise, the blocking plate 11 is still located on one side of the limit pin 14, so that when the subsequent spring 15 drives the limit pin 14 to reset, the limit pin 14 can drive the blocking plate 11 to move, so that the intake pipe 12 is blocked.

[0033] When the detection tube 7 is pulled out, the pull rope 17 returns to its original length, and the spring 15 drives the limit pin 14 to reset. At this time, under the elastic force of the spring 15, the limit pin 14 can be reset and then continue to move a greater distance, which can just move the blocking plate 11 to the air inlet pipe 12 in a blocked state, so that the suction box 18 can re-form a sealed space to prevent the entry of external gas, thereby realizing the automatic blocking work of the suction box 18 after suction, and facilitating the subsequent detection work.

[0034] A piston 4 is slidably connected inside the detection port 2, and the piston 4 and the detection tube 7 are fixedly connected. The piston 4 is provided with an exhaust hole 5, and a one-way valve is arranged inside the exhaust hole 5, and the one-way valve can only let out air; a sealing plate 9 is slidably connected to the bottom end of the detection port 2, and a vertical rod 6 is rotatably connected to the tank body 1, and the vertical rod 6 can drive the sealing plate 9 to move, thereby opening the lower end of the detection port 2.

[0035] The vertical rod 6 is arranged in the vertical direction, and the sealing plate 9 is arranged in the horizontal direction. The detection port 2 is rotatably connected with a gear, and a rack is connected to one side of the sealing plate 9. One end of the sealing plate 9 having the rack is located outside the detection port 2, and the gear and the rack are meshed with each other. The vertical rod 6 is fixedly sleeved with a first bevel gear, and the gear is fixedly connected with a second bevel gear. The first bevel gear and the second bevel gear are meshed with each other, so that when the vertical rod 6 rotates, it can drive the sealing plate 9 to move horizontally.

[0036] A method for using a fermentation tank that is convenient for detection, using the above-mentioned fermentation tank that is convenient for detection, comprises the following steps: S1: Put the detection tube 7 into the detection port 2, at this time the piston 4 slides in the detection port 2, the sealing plate 9 makes the bottom of the detection port 2 in a blocked state, and the gas in the detection port 2 is exhausted through the exhaust hole 5. After the exhaust is completed, the vertical rod 6 is rotated, and the vertical rod 6 drives the sealing plate 9 to move, so that the lower end of the detection port 2 is opened; S2: Move the detection tube 7 downward. When the floating plate 8 contacts the material 10 in the tank body 1, the floating plate 8 stops descending. As the detection tube 7 continues to descend, the pull rope 17 is hung on the guide wheel 16, and then drives the detection tube 7 to descend. The pull rope 17 drives the limit pin 14 to move out of the slot, releases the limit on the suction box 18, and at the same time, the limit pin 14 drives the sealing plug 21 to move out of the air inlet hole 26; S3: The push rod 19 falls on the bottom end of the detection tube 7. As the suction box 18 continues to descend, the push rod 19 drives the sealing ball 13 to move into the air inlet cavity 27. At this time, the gas above the material 10 enters the suction box 18 through the air inlet hole 26 and the air inlet pipe 12. S4: After the air intake is completed, the detection tube 7 is pulled upwards. At this time, the pull rope 17 no longer pulls the limit pin 14, and the spring 15 drives the limit pin 14 to reset. Due to the elastic force of the spring 15, the limit pin 14 on the right side moves to the initial position and then continues to move to the left. The limit pin 14 drives the blocking plate 11 to move, thereby blocking the air intake pipe 12.

[0037] In S1, both the vacuum box 18 and the detection tube 7 are provided with a vacuum port, and a one-way valve is provided in the vacuum port. The one-way valve allows the vacuum port to only allow air to escape but not to allow air to enter. When the vacuum box 18 is placed in the detection tube 7, air is firstly vacuumed through the vacuum port of the vacuum box 18 to extract the residual gas in the vacuum box 18, and then the vacuum box 18 is placed in the detection tube 7. After the installation of the detection tube 7 is completed, air is vacuumed through the vacuum hole of the detection tube 7 to extract the residual gas in the detection tube 7, and then the detection tube 7 is moved to the detection port 2.

[0038] Embodiment 2 Reference Figure 6-Figure 7 The other structures are the same as those in the first embodiment, except that the blocking problem of the air intake pipe is taken into consideration in this embodiment.

[0039] The air intake pipe 12 is slidably connected with a baffle plate 22, and the baffle plate 22 is fixedly connected with a pull rod 23. The limit pin 14 is provided with a pull groove 24 for the pull rod 23 to slide into. The limit pin 14 is connected to the detection tube 7 through a tension spring 25. The tension spring 25 is sleeved on the limit pin 14, one end of the tension spring 25 is connected to the detection tube 7, and the other end of the tension spring 25 is connected to the limit pin 14.

[0040] The length and depth of the groove 24 are suitable enough to facilitate the pull rod 23 to slide into the groove 24. In the initial state, the position of the baffle 22 makes the upper end of the intake pipe 12 in an open state, and the tension spring 25 makes the limit pin 14 slide into the groove. By setting the tension spring 25, the limit pin 14 will not continue to move after moving to the initial position.

[0041] The difference from Example 1 is that in S3, when the air suction box 18 falls to the bottom of the detection tube 7, the pull rod 23 falls into the pull groove 24. In S4, when the air suction box 18 is sealed, after the air intake is completed, the detection tube 7 is pressed downward, and the pull rope 17 drives the limit pin 14 to continue to move outward. The limit pin 14 pulls the baffle 22, and the baffle 22 blocks the air intake pipe 12. Then the detection tube 7 is pulled upward. At this time, the pull rope 17 no longer pulls the limit pin 14, and the tension spring 25 drives the limit pin 14 to reset. At this time, the pull rod 23 slides in the pull groove 24, and the baffle 22 does not move.

[0042] When the gas in the suction box 18 is subsequently detected, the detection mechanism used specifically includes a carbon dioxide sensor, a temperature and humidity sensor, a particle sensor, a biosensor, etc. The sensor can be adjusted according to the actual situation. Through gas detection, the operator can observe the fermentation situation in time to understand whether the environment required by the fermentation process is suitable and to what extent the entire fermentation process has proceeded, so as to grasp the fermentation situation.

[0043] The particle sensor is based on the principle of laser scattering and monitors the concentration of particles in the air in real time. The biosensor is an instrument that is sensitive to biological substances and converts their concentration into electrical signals for detection. It is an analytical tool or system composed of fixed biological sensitive materials as identification elements (including enzymes, antibodies, antigens, microorganisms, cells, tissues, nucleic acids and other biologically active substances), appropriate physical and chemical transducers (such as oxygen electrodes, photosensitive tubes, field effect tubes, piezoelectric crystals, etc.) and signal amplification devices.

[0044] By detecting the gas composition, we mainly detect the C02 concentration, temperature, humidity, impurity particles and bacteria at that location. Through the above differences, we can judge whether the fermentation is normal at this time. At the same time, we can compare it with the standard fermentation situation to understand whether the environment required by the fermentation process is suitable, and to what extent the entire fermentation process has proceeded, so as to judge the fermentation situation.

[0045] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
