Description

Technical Field

[0001] The utility model belongs to the field of mercury detection equipment, in particular to an automatic thiol cotton enrichment device. Background Art

[0002] Mercury is one of the important global pollutants and has attracted widespread attention. Mercury has different forms and different toxicities. Among them, methylmercury and ethylmercury have the strongest organic toxicity. For example, methylmercury is lipophilic, bioaccumulative, and has a macro-amplification effect. Its toxicity is hundreds of times that of inorganic mercury. Therefore, the determination of methylmercury in the environment, water quality, soil, food, and air has attracted attention; the content of methylmercury in the environment cannot be directly determined, and it is necessary to use thiol gauze for pre-enrichment and thiol cotton for secondary enrichment, and then measure it. The State Intellectual Property Office issued an authorization announcement on November 25, 2022, with the authorization announcement number CN217901350U: "A device for enriching organic mercury in the environment with thiol gauze". In the equipment disclosed in the patent, the thiol gauze is fixed on the corresponding fixed frame, and each fixed frame needs to be equipped with a corresponding motor to control its rotation and stirring to complete the enrichment of mercury, but the price of the motor is relatively high. Each thiol gauze is equipped with a motor, which increases the equipment cost, and the motor is inconvenient to repair after a failure, and the maintenance cost is high. Therefore, we designed an automatic thiol cotton enrichment device. Utility Model Content

[0018] Specifically, as shown in the figure, the lifting mechanism described in this embodiment includes a screw rod 20, and screw rods 20 are respectively provided on both sides of the control cabinet 1. The two screw rods 20 are sequentially located on the left and right sides of the control cabinet 1 and are arranged vertically and parallelly. The two ends of the screw rod 20 are respectively rotatably connected to the fixing plate 21, and the two ends of the screw rod 20 are respectively connected to the bearings on the bearing seat, and the bearing seat is fixedly installed on the corresponding fixing plate 21. The screw rod 20 is coaxially arranged with the corresponding bearing seat, and the fixing plate 21 is fixedly installed in the control cabinet 1. The screw rod 20 is respectively threadedly matched with a coaxial nut 22, and the nut 22 is fixedly installed on the lifting platform 4.

The second motor 24 is mounted on the corresponding fixing plate 21, and the second motor 24 is also fixedly mounted on the U-shaped plate 12. The output shaft of the second motor 24 passes through the avoidance hole on the U-shaped plate 12 and is fixedly connected to the second coupling 23. The U-shaped plate 12 is fastened to the corresponding fixing plate 21 by several bolts, and coaxial synchronous wheels 27 are fixedly mounted on the screw rods 20, respectively, and the synchronous wheels 27 are connected through the same synchronous belt 28. The second motor 24 is controlled to run, and the second motor 24 drives the second coupling 23 and the corresponding screw rod 20 to rotate, and then drives another screw rod 20 to rotate synchronously through the transmission of the synchronous wheel 27 and the synchronous belt 28. The rotation of the screw rod 20 causes the nut 22 to move upward or downward along the corresponding screw rod 20, thereby driving the lifting platform 4 to move. The moving direction of the nut 22 and the lifting platform 4 can be changed by the forward and reverse rotation of the second motor 24.

By pulling the lifting switch 50 upward or downward, the forward and reverse rotation of the second motor 24 can be controlled, thereby controlling the rise or fall of the lifting platform 4. The speed of the second motor 24 can be controlled by the speed regulator 51, thereby controlling the rise or fall speed of the lifting platform 4. The timer 54 can control the running time of the first motor 11. After adjusting the timer 54, the first motor 11 is operated by pressing the start button 53, thereby controlling the rotation of the stirring plate 7.

[0022] Furthermore, as shown in the figure, the cabinet door 3 described in this embodiment is a double-door, and the control cabinet 1 and the cabinet door 3 are equipped with a push-open lock 60, which is an existing mature technology and is not described in detail. The lower side of the cabinet door 3 is provided with an acrylic window 61, which is a transparent material, and the control cabinet 1 adopts an easy-open structure. Through the acrylic observation window 61, it is convenient to detect the internal reagent situation, and the push-open lock 60 is adopted, and the door opening and closing action is more convenient. The control cabinet 1 adopts an easy-open structure, which is more convenient for maintenance.

[0023] Furthermore, as shown in the figure, the lifting platform described in this embodiment is fixedly connected to one end of the accordion cover 70 on one side close to the cabinet door 3, and the other end of the accordion cover 70 is fixedly connected to the control cabinet 1. A partition 71 is fixedly installed in the control cabinet 1, and the upper end of the accordion cover 70 is fixedly connected to the bottom side of the partition 11.
