Description

TECHNICAL FIELD

[0001] The utility model relates to ash detection technical field, concretely is a coal ash rapid detection device. BACKGROUND

[0002] Coal ash refers to solid residues left after coal is completely combusted, and these residues are almost all from minerals in coal. When coal is combusted, organic substances in it are oxidized and decomposed, while minerals are not completely combusted and remain as ash, and this part of residues is referred to as coal ash.

[0003] In order to evaluate the use efficiency, environmental protection and economic benefits of coal, it is often necessary to detect coal ash by using a rapid continuous ash determination instrument.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0026] Please refer to Figures 1-4The utility model relates to a coal ash rapid detection device, including the detection appearance base 1, install the detection box 2 on the detection appearance base 1 upper end, install four supports 3 at the both ends of detection box 2 and install the conveying mesh belt 4 in the detection appearance base 1 with the inside of detection box 2, between the two supports 3 of detection box 2 export end fixedly connected with the U -shaped frame 5, the one end fixedly connected with the stacking box 6 of U -shaped frame 5 away from the support 3, the upper end of U -shaped frame 5 middle part is connected with rotating mechanism, the output of rotating mechanism is connected with monitoring mechanism, the other end of monitoring mechanism is connected with moving mechanism, the other side of moving mechanism is connected with two symmetrical clamping assemblies, and two clamping assemblies are located just above the conveying mesh belt 4.

[0027] As Figures 1-4 The coal ash rapid detection device in the utility model when using, only need to place the sample to be detected together with the container on the conveying mesh belt 4 at the import end of detection box 2, then normally through detection appearance base 1, detection box 2, support 3 and conveying mesh belt 4 to detect sample, and the sample and container will be transmitted from the export end of detection box 2 after detection, and the container will be monitored immediately by monitoring mechanism after moving out, and when the container reaches the set range, the electrical signal is transmitted to the processor in the detection appearance base 1, then the moving mechanism is started by controller, and the two clamping assemblies are controlled to move to the middle after the moving mechanism is started, so that the container on the conveying mesh belt 4 can be clamped, then the rotating mechanism is started by controller, and the moving mechanism, clamping assembly and container are rotated together, and when the container is rotated 180, the container is located just above the stacking box 6, then the two clamping assemblies are gradually released by controller, and the container will slide into the stacking box 6 for temporary storage due to the lack of greater extrusion force, and then the moving mechanism and clamping assembly are returned by rotating mechanism, and the second container and sample are transmitted, so that two detections can be carried out without stopping and human intervention.

[0028] Here needs to be explained specially:

[0029] 1, the above-mentioned detection appearance base 1, detection box 2, support 3 and conveying mesh belt 4 are all prior art in the present model "JZ-KH-10000A type rapid ash determination appearance", so the positional relationship, connection relationship, working principle etc. are not described in detail.

[0030] 2, the above-mentioned sample container is also prior art, and its appearance can be seen in Figure 1 , which is not described in detail here.

[0031] 3, the above-mentioned processor and controller are also prior art, which is not described in detail here.

[0032] As Figures 1-4As shown, the rotating mechanism comprises a rotating motor 11 and a rotating rod 12, the outer wall of the rotating motor 11 is fixedly connected with the upper surface of the middle part of the U-shaped frame 5, the output shaft of the rotating motor 11 is fixedly connected with the lower end of the rotating rod 12, and the other end of the rotating rod 12 is connected with the monitoring mechanism.

[0033] More specifically, when it is needed to control the rotating of the moving mechanism, the rotating motor 11 can be started by the controller, and the output shaft of the rotating motor 11 can drive the rotating rod 12 to rotate, so that the rotating of the monitoring mechanism and the moving mechanism can be controlled.

[0034] As shown, Figures 1-4 the monitoring mechanism comprises a rotating block 7, a supporting block 13 and a monitoring sensor 14, one end of the rotating block 7 is sleeved and fixedly connected with the outer wall of the rotating rod 12, the other end of the rotating block 7 is connected with the moving mechanism, the upper surface of the rotating block 7 is fixedly connected with the bottom surface of the supporting block 13, and the monitoring sensor 14 is fixedly connected with the inner wall of the upper end of the supporting block 13, and the monitoring end of the monitoring sensor 14 faces the detection box 2.

[0035] More specifically, when the rotating rod 12 starts to rotate, the rotating block 7 can rotate together, and then the rotating block 7 can drive the supporting block 13 and the monitoring sensor 14 connected above to rotate.

[0036] In addition, when the rotating block 7 does not rotate with the rotating rod 12, the monitoring sensor 14 can continuously monitor the direction of the conveying mesh belt 4 under the action of the supporting block 13, and when it is monitored that a container approaches, the information can be transmitted to the processor through wired or wireless signals, and then the moving mechanism can be started by the controller.

[0037] It should be particularly pointed out that the monitoring sensor 14 mentioned above can be an infrared sensor or a displacement sensor or other sensors with the same effect, and the specific model is not limited.

[0038] As shown, Figures 1-4 the moving mechanism comprises a clamping box 8, a clamping motor 9 and a bidirectional screw rod 10, the middle part of one side of the clamping box 8 is fixedly connected with the end of the rotating block 7 away from the rotating rod 12, the other side of the clamping box 8 is connected with two clamping assemblies, one end of the clamping box 8 is fixedly connected with the outer wall of the clamping motor 9, the output shaft of the clamping motor 9 is fixedly connected with one end of the bidirectional screw rod 10, and the end part of the bidirectional screw rod 10 penetrates through the two clamping assemblies. The side of the clamping box 8 away from the rotating block 7 is provided with a sliding groove 15, the ends of the two clamping assemblies away from the detection box 2 are located in the sliding groove 15, the end of the bidirectional screw rod 10 away from the clamping motor 9 is located in the sliding groove 15, the outer wall of the bidirectional screw rod 10 is rotationally connected with the inner wall of the penetration part of the clamping box 8, and the ends of the bidirectional screw rod 10 and the two clamping assemblies located in the sliding groove 15 are connected.

[0039] More specifically, when the container needs to be clamped, just start the clamping motor 9, the output shaft of the clamping motor 9 can rotate with the bidirectional screw rod 10, and then the bidirectional screw rod 10 can move the two clamping assemblies in the sliding groove 15 towards the middle at the same time, so that the container above the conveying mesh belt 4 can be clamped during the movement.

[0040] In addition, when the rotating rod 12 rotates, the clamping box 8 can be rotated with the rotating block 7, so that the two clamping assemblies and the container can be rotated above the stacking box 6.

[0041] As shown in Figures 1-4 The clamping assembly includes a clamping jaw 16 and a sliding block 17, one end of the clamping jaw 16 is fixedly connected with one end of the sliding block 17, the other end of the sliding block 17 is located in the sliding groove 15, the outer wall of the sliding block 17 is slidably connected with the inner wall of the sliding groove 15, and the sliding block 17 is sleeved and threadedly connected on the bidirectional screw rod 10. The side adjacent to the two clamping jaws 16 is arc-shaped, and the inner wall of the clamping jaw 16 arc surface is provided with a non-slip pad.

[0042] More specifically, when the bidirectional screw rod 10 rotates, the sliding block 17 can be controlled to move in the sliding groove 15, and then the sliding block 17 can move with the clamping jaw 16, so that the other clamping jaw 16 can clamp the container from both sides of the container. By providing a non-slip pad on the inner side of the clamping jaw 16, the probability of loosening and falling off of the container can be reduced.

[0043] It should be particularly noted that a pressure sensor can also be provided on the inner side of the clamping jaw 16 to sense the clamping pressure in real time, so that the container can be clamped more accurately and stably. Of course, the clamping pressure can also be programmed in the controller in advance according to the diameter of the container (i.e. the distance of the sliding block 17 moving in the sliding groove 15), and the programmable controller is also prior art, which will not be described in detail here. The specific implementation is not limited.

[0044] As shown in Figures 1-4 The depth of the stacking box 6 is not less than the height between the conveying mesh belt 4 and the top of the inner wall of the detection box 2, and the side of the stacking box 6 away from the detection box 2 is designed as an opening.

[0045] More specifically, in order to facilitate the movement of the container inside the detection box 2 and facilitate the heating of the sample inside the container by the high temperature in the detection box 2, the height of the container is certainly less than the height between the conveying mesh belt 4 and the top of the inner wall of the detection box 2. Therefore, at this time, the depth of the stacking box 6 is set to be not less than the height between the conveying mesh belt 4 and the top of the inner wall of the detection box 2, so that after the container is placed in the stacking box 6 by the clamping jaw 16, the collision between the clamping jaw 16 and the container can be avoided, and the normal return of the clamping jaw 16 is not affected.

[0046] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
