Description

[0001] The invention relates to the technical field of cooling tower detection equipment, and in particular to a scale detection device for a cooling tower. Background Art

[0002] A cooling tower is a device used to cool hot water to a lower temperature. A cooling tower generally includes components such as a water tank, a water pump, a piping system, and fillers. The fillers, pipes, and water tanks of a cooling tower are prone to scale.

[0003] The cooling tower filler increases the contact area between water and air to improve heat exchange, thereby achieving a cooling effect. The thermal conductivity of scale is low, so when scale adheres to the cooling tower filler, the heat exchange efficiency of the cooling tower is reduced, affecting the cooling effect;

[0004] In the prior art, the detection of scale in cooling tower packing generally includes visual inspection and the use of chemical reagents to detect the concentration of calcium and magnesium ions in water samples; cooling tower packing is usually arranged in a honeycomb shape, and the deeper parts of the cooling tower packing cannot be detected using the above methods, which causes limitations.

[0030] A lifting groove 17 is provided on the fixed block 11; the mounting block 12 is slidably connected in the lifting groove 17; a lifting motor 18 is fixedly connected in the lifting groove 17; a screw rod which is threadedly matched with the mounting block 12 is fixedly connected to the output end of the lifting motor 18; the detection block 13 is installed on the mounting block 12; a telescopic groove 2 is provided on the detection block 13; a telescopic rod 21 is slidably connected in the telescopic groove 2, and a telescopic electric push rod 22 is fixedly connected in the telescopic groove 2; the output end of the telescopic electric push rod 22 pushes the telescopic rod 21 to slide; a telescopic block 23 is installed on the telescopic rod 21; a contact cover 24 is installed on the telescopic block 23, and a pair of detection electrodes 25 and a discharge pipe 26 are installed on the telescopic block 23; a storage chamber 27 is provided in the detection block 13; a detection water pump 28 is fixedly connected in the storage chamber 27; the discharge pipe 26 and the detection water pump 28 are connected through a connecting pipe; a scale-dissolving solvent, such as acetic acid, is stored in the storage chamber 27.

[0031] In the present invention, a contact slot 3 is formed on the telescopic rod 21; the telescopic block 23 is slidably connected in the contact slot 3; a contact spring 31 is fixedly connected between the telescopic block 23 and the contact slot 3; and a spring switch 32 is fixedly connected in the contact slot 3.

[0032] In the present invention, a recovery chamber 33 is provided in the detection block 13; a recovery water pump 34 is fixedly connected in the recovery chamber 33; a recovery pipe 35 is fixedly connected to the telescopic block 23; and the input end of the recovery water pump 34 is connected to the recovery pipe 35.

[0033] In the present invention, a mounting groove 4 is provided on the mounting block 12; a support block 41 is stored in the mounting groove 4; the support blocks 41 are rotatably connected to each other head to tail, and a support groove 42 is provided on the support block 41; a clamping block 43 is slidably connected in the support groove 42; a clamping spring 44 is fixedly connected between the clamping block 43 and the support groove 42; the support block 41 close to the detection block 13 is fixedly connected to the detection block 13, and the support block 41 farthest from the detection block is rotatably connected to the mounting groove 4; a fixed frame 45 is fixedly connected to the fixed block 11; an adjusting block 46 is slidably connected to the fixed frame 45; an adjusting electric push rod 47 is connected between the adjusting block 46 and the fixed frame 45; a pushing electric push rod 48 is fixedly connected to the adjusting block 46; a pushing rod 49 is fixedly connected to the output end of the pushing electric push rod 48; the pushing rod 49 can push the clamping block 43 on the support block 41 in the fixed frame 45 to move.

[0034] In the present invention, the lateral moving block 1 is installed beside the cooling tower filler. When it is necessary to detect scale in the cooling tower filler, the lateral moving motor 15 on the lateral moving block 1 drives the corresponding screw to rotate, so that the longitudinal moving block 14 moves laterally with the fixed block 11, the mounting block 12 and the detection block 13. The motor on the longitudinal moving block 14 drives the corresponding screw to rotate, so that the fixed block 11 moves longitudinally with the mounting block 12 and the detection block 13, thereby controlling the movement of the detection block 13.

[0035] The lifting motor 18 drives the corresponding screw rod to rotate, so that the installation block 12 moves up and down. Since the fixing frame 45 is fixed on the fixing block 11, when the installation block 12 moves up and down, the support block 41 in the installation block 12 extends out of the fixing frame 45, pushes the adjustment electric push rod 47 to pull the adjustment block 46 and the electric push rod 48 downward, so that the push rod 49 moves downward and is located on the left side of the locking block 43, and then pushes the electric push rod 48 to pull the push rod 49, so that the push rod 49 pushes the locking block 43 to move rightward in the support groove 42 and inserts it into the support groove 42 on the right side of the support block 41, so that the support blocks 41 are connected, and then the push rod 49 presses the locking block 43 downward, so that the locking block 43 is locked with the support groove 42; when it is necessary to release the connection between the support blocks 41 so that the detection block 13 returns to its original position, the push rod 49 pulls the locking block 43 upward, so that the locking spring 44 pushes the locking block 43 to reset;

[0036] The support block 41 pushes the detection block 13 and extends into the gap of the cooling tower filler. Then the telescopic electric push rod 22 pushes the telescopic rod 21 to move, so that the contact cover 24 on the telescopic block 23 contacts the cooling tower filler, and the telescopic block 23 squeezes the contact spring 31 and the spring switch 32. The spring switch 32 is connected to the controller, so that the telescopic electric push rod 22 stops pushing. Then the detection water pump 28 fills the solvent stored in the storage chamber 27 into the discharge pipe 26. After the solvent enters the contact cover 24 and contacts the cooling tower filler, it dissolves the scale on the cooling tower filler, so that the scale is dissolved in the solvent, and the free ions in the solvent increase, thereby increasing the conductivity. The detection electrode 25 is connected to the controller circuit, and the conductivity between the two detection electrodes 25 increases, so that the detected current increases. Therefore, the present invention detects that there is scale on the cooling tower filler, and the present invention detects the amount of scale according to the size of the current change.

[0037] The present invention sets a contact cover 24 in contact with the cooling tower filler, and fills the contact cover 24 with a solvent to dissolve scale, so that the conductivity of the solvent increases, thereby increasing the current passing between the detection electrodes 25, so that the present invention detects the presence of scale in the cooling tower filler.

[0038] Embodiment 2: Based on embodiment 1, in the present invention, the support blocks 41 are fixedly connected with a same flexible belt 5 ; the fixing frame 45 is fixedly connected with an auxiliary motor 51 ; the output end of the auxiliary motor 51 is fixedly connected with a roller 52 in contact with the flexible belt 5 .

[0039] Refer to the instruction manual Figure 5 and 6 In the present invention, an auxiliary groove 6 is provided on the detection block 13; an auxiliary electric push rod 61 is fixedly connected in the auxiliary groove 6; an auxiliary rod 62 is fixedly connected to the output end of the auxiliary electric push rod 61; and a rolling wheel 63 is installed at the top of the auxiliary rod 62.

[0040] In the present invention, a rolling groove 64 is formed at the top of the auxiliary rod 62 ; a rolling block 65 is slidably connected in the rolling groove 64 ; a rolling spring 66 is fixedly connected between the rolling groove 64 and the rolling block 65 ; and a spring switch 32 is also fixedly connected in the rolling groove 64 .

[0041] In the present invention, when the support block 41 extends out of the fixed frame 45, the auxiliary motor 51 drives the roller 52 to rotate, so that the roller 52 drives the flexible belt 5 to pull the support block 41 to move, thereby preventing the support block 41 in the installation groove 4 from getting stuck during the upward rotation when moving to the position of the fixed frame 45;

[0042] In the present invention, an auxiliary rod 62 and a rolling wheel 63 are provided on the detection block 13, and the auxiliary electric push rod 61 pushes the auxiliary rod 62 to extend out of the auxiliary groove 6, so that the rolling wheel 63 contacts the cooling tower filler. Therefore, when the detection block 13 moves in the cooling tower filler, the rolling wheel 63 rolls, and the auxiliary rod 62 is supported on the cooling tower filler to support the support block 41 and the detection block 13, so as to prevent the support block 41 and the detection block 13 from being supported by only one side, thereby preventing the locking block 43 from being damaged.
