Description

Technical Field

[0001] This utility model belongs to the field of biodegradable material detection technology, specifically relating to a biodegradable material detection device. Background Technology

[0002] Biodegradable materials are a class of natural or synthetic biomedical materials that, within a living organism, are continuously degraded and absorbed by the body under the influence of bodily fluids, acids, and nucleic acids. Ultimately, the implanted material is completely replaced by new tissue. These include polymers such as peptides, polyamino acids, polyesters, polylactic acid, chitosan, and collagen / gelatin. The degradation efficiency of biodegradable materials is extremely important, therefore, testing is necessary.

[0003] Problems with existing technology:

[0004] In the prior art, the patent application CN211348250U, entitled "A Biodegradable Detection Device", describes the detection device as including an upper plastic shell, a lower plastic shell, and a reagent strip. The upper plastic shell is provided with an observation window and a sample application hole. A fixing protrusion is provided on the inner side of the upper plastic shell. A reagent strip slot and a boss are provided on the inner side of the lower plastic shell. A fixing groove is provided in the center of the boss. The boss surrounds the reagent strip slot. The reagent strip is installed in the reagent strip slot. The fixing protrusion is located in the fixing groove.

[0005] The aforementioned device only observes the degradation effect of biodegradable materials through an identification window to achieve the detection purpose. However, this method results in low detection efficiency due to the uneven mixing of biodegradable materials with soil. Furthermore, it is not suitable for the joint detection of multiple materials. In addition, the device is not convenient for placing and removing the degradation container during the detection process, which affects the detection efficiency. Utility Model Content

[0006] The purpose of this invention is to provide a biodegradable material detection device that can solve the problems of insufficient detection accuracy, inability to detect multiple materials simultaneously, and inconvenience in handling the degradation tanks used for detection in current biodegradable material detection devices.

[0007] The specific technical solution adopted by this utility model is as follows:

[0008] A biodegradable material testing device includes a cabinet and a connecting pipe. A testing box is installed on the top of the cabinet. An exhaust pipe is fixedly connected to the top of the testing box through a gas collecting shell. A lifting cylinder is installed inside the testing box. A carbon dioxide detector is installed on one side of the testing box.

[0009] The output end of the lifting cylinder is fixedly connected to a mixing mechanism, which is movably installed through the degradation tank and the rotating mechanism. A telescopic corrugated pipe is provided between the mixing mechanism and the gas collecting shell.

[0010] The mixing mechanism includes a first motor, a mounting bracket, and a sealing cover. The first motor drives the mixing rod fixedly connected to the bottom to rotate. The top of the sealing cover is fixedly connected to the mounting bracket, which is fixedly installed to the carrier plate via the first motor.

[0011] The rotating mechanism includes a support base and a second motor. The support base is used for rotating the base and the cabinet. The second motor is used to drive the drive gear to rotate. A driven gear is meshed with one side of the drive gear.

[0012] The carrier plate moves vertically inside the detection box via a lifting cylinder. The connecting pipe is inserted into the inside of the sealing cover and is fixedly connected to the gas collecting shell via a telescopic corrugated pipe.

[0013] The second motor is fixedly installed inside the cabinet, and the second motor drives the driven gear to rotate through the driving gear.

[0014] The bottom of the base is surrounded by ball bearings, which are used to rotatably connect the base to the detection box. The drive gear drives the support to rotate through the driven gear.

[0015] The mounting bracket is welded to the top of the sealing cover, and the mixing rod is rotatably mounted with the mounting bracket and the sealing cover.

[0016] The technical effects achieved by this utility model are as follows:

[0017] This invention utilizes a lifting cylinder installed inside the testing chamber to drive a mixing mechanism to move vertically. This movement moves the sealing cover to the top of the degradation tank and the mixing rod to the inside of the tank. Activating the first motor drives the mixing rod to rotate, thus uniformly mixing the soil and biodegradable materials inside the tank, accelerating the degradation rate and improving testing efficiency. Through connecting pipes, telescopic corrugated pipes, a gas collecting shell, and an outlet pipe, the carbon dioxide generated during degradation is sent to a carbon dioxide detector for concentration detection. The ratio of this concentration to the theoretical maximum release rate represents the biodegradation rate. Each degradation tank's connecting pipe is equipped with a solenoid valve, allowing for the simultaneous detection of multiple materials by controlling the valves' operation.

[0018] This invention utilizes a rotating mechanism installed inside the testing box. The second motor of the rotating mechanism drives the active gear to rotate. Since the active gear meshes with the driven gear, the support base can rotate. Because the degradation tank is movably mounted on the top of the base, the rotation of the base can cause the degradation tank to rotate synchronously, thus facilitating the placement and removal of the degradation tank.

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] like Figure 1-4 As shown, a biodegradable material detection device includes a cabinet 1 and a connecting pipe 10. A detection box 2 is installed on the top of the cabinet 1. An outlet pipe 4 is fixedly connected to the top of the detection box 2 through a gas collecting shell 3. A lifting cylinder 5 is installed inside the detection box 2. A carbon dioxide detector 11 is installed on one side of the detection box 2.

[0027] The output end of the lifting cylinder 5 is fixedly connected to the mixing mechanism 7. The mixing mechanism 7 is movably installed with the rotating mechanism 8 via the degradation tank 9. A telescopic bellows 6 is provided between the mixing mechanism 7 and the gas collecting shell 3.

[0028] The mixing mechanism 7 includes a first motor 72, a mounting bracket 73, and a sealing cover 74. The first motor 72 is used to drive the mixing rod 75, which is fixedly connected to the bottom, to rotate. The top of the sealing cover 74 is fixedly connected to the mounting bracket 73, which is fixedly installed to the carrier plate 71 through the first motor 72.

[0029] See attached document Figure 2 and Figure 4 In this embodiment, the rotating mechanism 8 includes a support base 82 and a second motor 85. The support base 82 is used for the base 81 to be rotatably mounted with the cabinet 1. The second motor 85 is used to drive the drive gear 84 to rotate. A driven gear 83 is meshed on one side of the drive gear 84.

[0030] In the above embodiment, the second motor 85 can drive the drive gear 84 to rotate, and the rotation of the drive gear 84 can drive the driven gear 83 meshing with it to rotate. The top of the base 81 is movably mounted with the degradation tank 9 through the mounting seat, and the support seat 82 at the bottom of the base 81 is rotatably mounted inside the cabinet 1.

[0031] The base 81 has three sets of mounting seats arranged around its top. The mounting seats can be made of magnetic material and can be started and stopped by electric control. At the same time, a metal plate can be installed at the bottom of the degradation tank 9. Therefore, the mounting seats can be used to install the degradation tank 9, making it more convenient to put the degradation tank 9 in and out.

[0032] More specifically, the second motor 85 is fixedly installed inside the cabinet 1. The second motor 85 drives the driven gear 83 to rotate through the drive gear 84, and the drive gear 84 drives the support base 82 to rotate through the driven gear 83. Since the support base 82 is fixedly connected to the bottom of the base 81, the degradation tank 9 can be driven to rotate when the support base 82 rotates, which facilitates the removal and placement of the degradation tank 9.

[0033] The bottom of the base 81 is surrounded by ball bearings, which are rotatably installed inside the base 81 and the bottom of the ball bearings is in contact with the detection box 2. Therefore, the base 81 and the detection box 2 can be rotatably connected by the ball bearings.

[0034] See attached document Figure 2 and Figure 3 In this embodiment, the carrier plate 71 moves vertically inside the detection box 2 via the lifting cylinder 5, and the connecting pipe 10 is inserted into the inside of the sealing cover 74. The connecting pipe 10 is fixedly connected to the gas collecting shell 3 via the telescopic corrugated pipe 6.

[0035] In the above embodiment, the lifting cylinder 5 can drive the carrier plate 71 to move vertically inside the detection box 2. The movement of the carrier plate 71 allows the mixing rod 75 to enter the degradation tank 9. Under the action of the first motor 72, the mixing rod 75 is driven to rotate to uniformly mix the biodegradable material and soil, thereby improving the degradation efficiency.

[0036] Furthermore, due to the action of microorganisms in the soil, the biodegradable material can be degraded inside the degradation tank 9. During the degradation process, the biodegradable material will produce carbon dioxide gas, which can be discharged from the inside of the degradation tank 9 through the connecting pipe 10.

[0037] A solenoid valve can be installed in the middle of the connecting pipe 10. By opening the solenoid valve, the carbon dioxide gas accumulated in the degradation tank 9 can enter the gas collecting shell 3 through the connecting pipe 10 and the telescopic corrugated pipe 6, and be sent to the carbon dioxide detector 11 for concentration detection under the action of the gas outlet pipe 4.

[0038] More specifically, the mounting bracket 73 is welded to the top of the sealing cover 74, and the first motor 72 fixedly mounted on the top of the mounting bracket 73 is fixedly mounted to the carrier plate 71. Therefore, the carrier plate 71 can drive the sealing cover 74 to move vertically through the first motor 72 and the mounting bracket 73. The mixing rod 75 is rotatably mounted to the mounting bracket 73 and the sealing cover 74, so the mixing rod 75 can be driven to rotate by the first motor 72.

[0039] Furthermore, a ring of fluorescent lamps can be installed inside the sealing cover 74 to simulate the natural environment inside the degradation tank 9. A spray structure can also be added inside the sealing cover 74 to simulate the humidity in the natural environment, thereby improving the detection accuracy of biodegradable materials.

[0040] The working principle of this utility model is as follows: After a specific amount of soil and biodegradable material is fed into the interior of the degradation tank 9, the degradation tank 9 is installed on the surface of the base 81. By starting the second motor 85, the drive gear 84 is rotated, and the driven gear 83 is driven to rotate the support base 82, so that the base 81 can rotate the degradation tank 9 to the bottom of the mixing mechanism 7.

[0041] By activating the lifting cylinder 5, the carrier plate 71 moves the mixing rod 75 down into the interior of the degradation tank 9. Simultaneously, the sealing cover 74 moves to the top of the degradation tank 9 and seals it. Then, the mixing rod 75 can be rotated by activating the first motor 72, thereby uniformly mixing the soil and biodegradable material. When the biodegradable material degrades under the action of microorganisms in the soil, carbon dioxide is generated. Since a solenoid valve is installed in the middle of the connecting pipe 10, the carbon dioxide will remain inside the degradation tank 9. By opening the solenoid valve, the carbon dioxide can enter the gas collection shell 3 through the connecting pipe 10 and the telescopic corrugated pipe 6. The carbon dioxide is sent to the carbon dioxide detector 11 through the gas outlet pipe 4 for concentration detection. The ratio of the concentration to the theoretical maximum release amount is used to represent the biodegradation rate of the material, thereby realizing the detection of the degradation effect of the biodegradable material.

[0042] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
