Description

Technical Field

[0001] The invention relates to the technical field of digestion detection equipment, and in particular to a digestion colorimetric detection device. Background Art

[0002] As people's living standards continue to improve, water quality maintenance has also received increasing attention. Water pollution not only affects industrial production, increases equipment corrosion, affects product quality, and even makes production impossible, but more importantly, water pollution also affects people's lives, destroys the ecology, and directly endangers human health, causing great damage. Water quality testing is a direct way to grasp the degree of water pollution and provides important data support for decision-making and governance. During the water testing process, some specific pollution factors need to be digested in a high-temperature, high-pressure, sealed environment, and then color development and colorimetric measurements are performed to further calculate the content of the measured factors.

[0003] At present, in order to monitor water quality in real time and reduce workload, online detectors are often used to process and detect water samples. The digestion unit and colorimetric unit of the online detector are integrated structures with compact structure. Low cost and fast measurement speed, but the position of colorimetric detection is fixed and cannot be adjusted. In colorimetric detection, the liquid level of the test agent must exceed the height of the colorimetric detection optical path. The colorimetric device with a fixed detection position height has the following disadvantages: (1) The injection volume of each reagent needs to be accurately calculated to meet the total volume requirements after mixing, and the calculation and operation are complicated; (2) Even if a small amount of reagent is required for the reaction, it must be scaled up in proportion to meet the total volume requirements, which wastes reagents and causes serious secondary pollution; (3) Layered extraction reaction is not conducive to adjusting the optimal detection position; (4) Different instruments need to replace different detection positions, and compatibility and interchangeability are poor. Summary of the invention

[0004] In view of the above problems, the purpose of the present invention is to provide a new digestion and colorimetric detection device, which integrates high-temperature digestion and colorimetric detection functions. The detection position can be adjusted up and down, and the operation detection has high detection accuracy. It has good compatibility with instruments with different parameters, meets the optimal ratio of reaction reagents, reduces the amount of reagents used, and reduces secondary pollution.

In the present invention, the cross section of the digestion assembly seat 1 is a "U"-shaped structure, the digestion cup is arranged inside the digestion assembly seat 1, and a pair of sliders 1 4 are symmetrically arranged on both side surfaces of the digestion assembly seat 1, the receiving light channel 2 and the emitting light channel 3 pass through the sliders 1 4, and a pair of fixing plates 5 are horizontally symmetrically arranged on both side surfaces of the digestion assembly seat 1, and a slider 2 6 is respectively arranged on the fixing plates 5, and the slider 2 6 is connected to the slider 1 4 through a connecting rod 7, and the two ends of the connecting rod 7 are respectively hinged and fixed on the slider 1 4 and the slider 2 6, and when the slider 2 6 moves left and right, the connecting rod 7 drives the slider 1 4 to move up and down.

[0020] The working principle of the present invention is as follows: the receiving light channel and the transmitting light channel are fixed on the slider one, the slider one can slide up and down to drive the receiving light channel and the transmitting light channel (i.e., the detection point) to move up and down, the slider two can move horizontally and is connected to the slider one through a connecting rod, and when the slider two moves horizontally, the slider one is driven to move up and down through the connecting rod. When the slider two is located above the slider one, when the slider two is close to the side of the digestion group seat, the slider one moves downward, that is, the detection point moves downward, otherwise, the slider one moves upward, that is, the detection point moves upward; when the slider two is located below the slider one, when the slider two is close to the side of the digestion group seat, the slider one moves upward, that is, the detection point moves upward, otherwise, the slider one moves downward, that is, the detection point moves downward. In the present invention, the movement of the slider two can be manually controlled.

[0021] In this embodiment, the fixed plate 5 is located above the slider 1 4, and a groove is provided in the middle of the front and rear sides of the slider 2 6 along the length direction of the fixed plate 5. A rectangular hole is provided in the middle of the fixed plate 5, and the middle of the slider 2 6 is stuck in the rectangular hole and slides left and right along the rectangular hole. The hinge point between the connecting rod 7 and the slider 2 6 is located below the slider 2 6 and close to one end of the side of the digestion assembly seat 1. In this embodiment, the slider 2 6 is arranged at the top in combination with the rectangular hole and the groove. On the one hand, it is convenient to observe and ensure the symmetry of the position of the slider 2 6, and on the other hand, it is convenient to adjust the movement of the slider 2 6.

[0022] In this embodiment, we also provide a screw rod 8, one end of which is rotatably fixed on the digestion assembly seat 1, and the other end is fixed on the fixed plate 5, specifically, it can be fixed on the fixed plate 5 through a fixed block. The screw rod 8 passes through the slider 2 6 and can drive the slider 2 6 to slide by rotating.

[0023] In this embodiment, a nut 9 is fixedly arranged at one end of the screw rod 8 which is arranged on the fixed plate. The nut 9 is fixed to the end of the screw rod 8. When the nut 9 is turned, the screw rod 8 rotates together and the position of the nut 9 on the screw rod 8 remains unchanged. Anti-slip grooves are arranged horizontally and parallelly on the outer circumference of the nut 9. The clamping device is an arc-shaped clamping ring 10 matching the nut 9. The interior of the clamping ring 10 is arranged with stripes horizontally and parallelly. A spring 11 is arranged on the outer side of the arc-shaped clamping ring 10. The other end of the spring 11 is fixedly arranged on the fixed plate 5. Similarly, the spring 11 can be fixed on the fixed plate 5 by a fixing block. The arc-shaped clamping ring 10 is provided with a spring 11. The bottom of the clamping ring 10 can slide along the upper surface of the fixed plate. Specifically, a sliding groove can be set on the fixed plate, and the lower end of the arc-shaped clamping ring slides along the sliding groove. The arc-shaped clamping ring 10 clamps the screw rod 8 under the action of the spring 11. When adjusting, you only need to manually turn the clamping ring 10 to compress the spring 11, and the clamping ring 10 is disengaged from the nut 9. The screw rod can be manually rotated to make adjustments. After the adjustment is completed, loosen the clamping ring 10. The clamping ring 10 will be against the outer peripheral surface of the nut under the action of the spring 11. The setting of the stripes can better ensure the clamping effect.

[0024] In this embodiment, a scale 13 is also provided on the upper surface of the fixed plate 5. The scale 13 is parallel to the length direction of the rectangular hole and is arranged on the outside of the slider 2 6, so as to facilitate the adjustment of the consistency of the position of the slider 2 6, thereby ensuring the correspondence between the receiving light channel 2 and the transmitting light channel 3.

[0025] In this embodiment, a groove is provided in the middle of the front and rear sides of the slider 4 along the vertical direction, and rectangular holes are provided on the two side surfaces of the digestion assembly seat 1. The slider 4 is clamped in the rectangular hole through the groove and slides up and down along the rectangular hole. The hinge point between the connecting rod 7 and the slider 4 is located on the upper surface of the slider 4.
