[0022] Figure 4 This is a picture of an existing digester.
[0023] The components include: digester body 10, digestion tank 11, positioning cover 20, support plate 21, moving plate 30, ball screw module 31, lifting plate 40, lifting cylinder 41, guide rod 42, crossbeam plate 43, pressure sensor 50, suction head 60, air chamber box 61, hose 62, air pump 63, positioning plate 70, positioning hole 71, baffle 80, limit hole 81, and controller 90. Detailed Implementation
[0024] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.
[0025] like Figure 1-3In this first embodiment, a water quality online detection and digestion device includes...
[0026] The digester body 10 has several digestion grooves 11 on its upper surface;
[0027] The positioning cover 20 is disposed on the upper surface of the digester body 10 with its opening facing downward. The digestion groove 11 is located within the range of the positioning cover 20, and the side wall of the positioning cover 20 has an opening.
[0028] The support plate 21 is L-shaped, and its horizontal end is connected to the upper end of the side wall where the opening of the positioning cover 20 is located;
[0029] The movable plate 30 is movably mounted on the horizontal plate of the support plate 21 and can enter and exit through the opening;
[0030] The lifting plate 40 is mounted on the movable plate 30 in a height-adjustable manner.
[0031] Pressure sensor 50 is fixedly connected to the lower surface of lifting plate 40;
[0032] The air chamber 61 is disposed on the stress surface of the pressure sensor 50;
[0033] Several suction heads 60 are respectively disposed on the lower end wall of the air chamber box 61, and each suction head 60 has an individual solenoid valve;
[0034] Positioning plate 70 and baffle 80 are respectively set on the vertical plate of baffle 80. Positioning plate 70 is provided with positioning hole 71 corresponding to the position of each suction head, and baffle 80 is provided with limit hole 81 corresponding to the position of positioning hole 71.
[0035] This embodiment is implemented as follows:
[0036] In use, the test tube is first placed on the baffle 80 through the positioning hole 71. Since the limiting hole 81 allows a portion of the bottom of the test tube to enter, the test tube is kept vertical and cannot pass through the limiting hole 81. Then, the moving plate 30 drives the lifting plate 40 to move, which in turn drives the suction head 60 to move and rise, allowing the suction head 60 to move downwards and contact the stopper of the test tube. At this time, the pressure sensor 50 senses the pressure. When the pressure exceeds the set value, the lifting plate 40 stops moving, and the suction head 60 can then hold the stopper. The lifting plate 40 then moves upwards, causing the suction head 60 to move the test tube away from the positioning hole 71 and send the test tube into the digestion tank 11. Since the suction head 60 in this application has a solenoid valve, it can be used to open and close different solenoid valves to control which suction heads 60 can grip the test tube.
[0037] Please see Figure 1 , 2A ball screw module 31 is provided between the side wall of the positioning cover 20 and the vertical plate of the support plate 80. The ball screw of the ball screw module 31 is threadedly connected to the moving plate 30. The horizontal plate of the support plate 21 is flush with the upper wall of the positioning cover 20. The moving plate 30 slides in contact with the horizontal plate of the support plate 21 and the upper wall of the positioning cover 20.
[0038] The ball screw module 31 provided in this application can drive the moving plate 30 to move along the lower surface of the upper end wall of the positioning cover 20 and the lower surface of the horizontal plate of the support plate 21.
[0039] Please see Figure 2 The movable plate 30 is provided with a U-shaped crossbeam plate 43, and a lifting cylinder 41 is provided on the crossbeam plate 43. The output end of the lifting cylinder 41 is fixedly connected to the lifting plate 40. The lifting plate 40 is provided with a number of guide rods 42 that slide through the crossbeam plate 43.
[0040] This application uses a lifting cylinder 41 to drive the lifting plate 40 to move vertically, and the guide rod 42 can increase the stability of the vertical movement of the lifting plate 40.
[0041] Please see Figure 2 An air pump 63 is provided on the side wall of the vertical plate of the support plate 80. The air pump 63 is connected to the air chamber box 61 through a hose 62.
[0042] This application uses an air pump 63 to work with a hose 62 to adjust the air pressure inside the air chamber box 61, enabling the suction head 60 to grip and release.
[0043] Please see Figure 1 , 2 The upper wall of the positioning cover 20 is equipped with a controller 90, which is electrically connected to the air pump 63, the ball screw module 31, the suction head 60, the digester body 10, the lifting cylinder 41, and the pressure sensor 50. The controller 90 has a speaker.
[0044] The controller in this application includes a PLC controller, a touch screen display, and a speaker. The PLC controller can control the opening and closing of electrical components, the touch screen display can be used for testing personnel to input command information, and the speaker can emit prompt sounds to remind testing personnel.
[0045] A programmable logic controller (PLC) is a digital electronic system specifically designed for industrial applications. It uses a programmable memory to store instructions for performing logical operations, sequential control, timing, counting, and arithmetic operations, controlling various types of machinery or production processes through digital or analog inputs and outputs.
[0046] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
