Description

Technical Field

[0001] The utility model relates to the technical field of fly ash slurry, and specifically, to a device for detecting the spread of fly ash slurry. Background Art

[0002] Fly ash is the most common filling raw material in the process of concrete production. Practice shows that fly ash can effectively improve the fluidity of the filling slurry. The fluidity of fly ash slurry refers to the smoothness of the fly ash slurry flowing under the action of its own weight or external force. The better the fluidity of the slurry, the less likely the slurry is to block the transportation pipeline, and it can reduce pipeline wear and is conducive to pumping. The spread of fly ash slurry is an important index to measure the fluidity of fly ash slurry, and accurately measuring the spread of fly ash slurry is of great significance.

[0003] After retrieval, the Chinese patent publication number CN 203405392 U discloses a "rapid detection device for the spread of fly ash slurry, including two discs with scales marked on two mutually perpendicular diameters and a cylinder with both ends open. The diameter of the disc is 5-9 times the diameter of the cylinder. The utility model has fast detection speed, accurate detection data, no sticking and deformation, simple operation, standard steps, high work efficiency and low labor intensity".

[0004] The above patent is deformed: using stainless steel thin plate as the material, with a smooth surface, clear scales and accurate readings. However, in the above patent, since the detection can only be carried out in groups during the detection process, the detection speed is slow, and the detection data also has contingency. In addition, since the above patent lacks a fly ash recovery device, after the detection process is over, the staff may directly discard the fly ash used for detection, further causing waste of resources. Summary of the Utility Model

[0005] The utility model provides a device for detecting the spread of fly ash slurry, which solves the problem that it is difficult for single fibers to independently penetrate through the filter holes in the prior art.

[0006] The technical solution of the utility model is as follows: A device for detecting the spread of fly ash slurry, including a bottom plate. Four uniformly distributed recovery boxes are installed at the upper end of the bottom plate, and two symmetrically distributed detection plates are installed at the upper end of the recovery boxes. Two symmetrically distributed rotating rods are installed at the upper end of the recovery boxes. Moving rods are respectively installed on the lower surfaces of the two detection plates, and the two moving rods are symmetric to each other. A connecting rod is installed at the lower end of the moving rod, and a linkage rod is installed on the connecting rod. The other end of the linkage rod is installed with a motor. An installation plate is installed on the inner wall of the lower end of the recovery box, and the motor is installed on the outer wall of the installation plate. A sliding rod is installed at the upper end of the recovery box, and a plurality of uniformly distributed brushes are fixedly connected to the lower surface of the sliding rod. A pull rod is fixedly connected to the front end of the sliding rod; Two symmetrically distributed electric push rods are installed on the upper surface of the bottom plate, and connection blocks are fixedly connected to the upper ends of the two electric push rods. A connection sleeve is fixedly connected between the two connection blocks, and a dispersion pipe is installed inside the connection sleeve. The upper end of the dispersion pipe is communicated with a feed funnel.

[0007] Preferably, a sliding groove is opened at the inner wall of the upper end of the recovery box, and the sliding rod is slidably installed inside the sliding groove. By moving the sliding rod on the upper surface of the detection plate, the brush can clean the fly ash slurry remaining on the upper surface of the detection plate, further avoiding waste of resources.

[0008] Preferably, a chute is opened on the outer wall of the front end of the recovery box, and the pull rod is slidably installed inside the chute. By pushing the pull rod, the sliding rod can move on the upper surface of the detection plate, and the brush on the lower surface of the sliding rod can clean the upper surface of the detection plate, further avoiding waste of fly ash slurry.

[0009] Preferably, horizontal and vertical scale lines are engraved on the upper surface of the detection plate, and sealing strips are fixedly connected to the outer walls of the two groups of detection plates close to each other. The setting of the scale lines facilitates the measurement and calculation of the spread of fly ash slurry. The setting of the sealing strips can effectively prevent the fly ash slurry from leaking into the recovery box, effectively ensuring the accuracy of the detection data.

[0010] Preferably, both groups of detection plates are slidably sleeved outside the rotating rods. The detection plates start to rotate into the recovery box under the action of the moving rods, further enabling the fly ash slurry to enter the recovery box for recycling after the detection is completed, effectively avoiding waste of resources.

[0011] Preferably, one end of each of the two sets of moving rods is hingedly connected to the lower surface of the detection plate, and the other end of each of the two sets of moving rods is hingedly connected to the connecting rod. Under the action of the moving rods, the detection plate can be operated to close and open. At this time, the fly ash slurry enters the inside of the recovery box as the detection plate opens, so that the fly ash slurry can be collected.

[0012] Preferably, the linkage rod is hingedly connected to the connecting rod. By starting the motor, the motor drives the linkage rod to start rotating. Further, under the action of the connecting rod, the linkage rod drives the two sets of moving rods to move, and finally the collection of the fly ash slurry can be completed, effectively improving the utilization rate of the fly ash slurry.

[0013] Preferably, a discharge port is provided on the outer wall of the recovery box, and a sealing plug is installed inside the discharge port. The setting of the discharge port enables the fly ash slurry inside the recovery box to be discharged after a certain amount is filled.

[0014] The technical effects and advantages of the present utility model: By installing a dispersion pipe at the upper end of the detection plate, the upper end of the dispersion pipe is connected to a feed hopper. When starting to detect the spread of the fly ash slurry, first introduce the fly ash slurry from the feed hopper. Under the action of the dispersion pipe, the fly ash slurry will be evenly dispersed on the detection plates at different positions. The lower end of the dispersion pipe is initially close to the upper end of the detection plate. When starting the detection, the electric push rod can be started. Under the action of the connecting block and the connecting sleeve, the dispersion pipe will be driven to slowly move upward. Further, the fly ash slurry will start to slowly spread on the detection plate. After a period of time when the fly ash slurry spread ends, the value on the detection plate can be read. By simultaneously conducting four groups of detection tests, the detection speed and data accuracy of the fly ash slurry spread can be effectively improved. In addition, an installation plate is installed inside the recovery box, and a motor is installed on the installation plate. After completing the detection test of the fly ash slurry spread, the motor can be started. The motor drives the two sets of moving rods to move through the linkage rod and the connecting rod. Further, the two detection plates will start to slowly rotate downward under the action of the moving rods. At this time, the fly ash slurry on the upper surface of the detection plate will slowly flow into the inside of the recovery box. After all the fly ash slurry flows into the recovery box, start the motor to restore the two detection plates to the initial close position. Then push the sliding rod so that the multiple brushes at the lower end of the sliding rod can clean the fly ash slurry remaining on the upper surface of the detection plate. Also, because there is a gap between the left side of the detection plate and the left inner wall of the recovery box, the remaining fly ash slurry can enter the recovery box from the gap, so that the recovery of the fly ash slurry can be completed, effectively avoiding waste of resources.

Four uniformly distributed recovery boxes 2 are installed at the upper end of the bottom plate 1, and two symmetrically distributed detection plates 3 are installed at the upper end of the recovery box 2. A sliding groove is provided at the inner wall of the upper end of the recovery box 2, and a sliding rod 11 is slidably installed inside the sliding groove.

A chute is provided on the front outer wall of the recovery box 2, and a pull rod 13 is slidably installed inside the chute. By pushing the pull rod 13, the sliding rod 11 can move on the upper surface of the detection plate 3, and the brush 12 on the lower surface of the sliding rod 11 can clean the upper surface of the detection plate 3, further avoiding the waste of fly ash slurry. Horizontal and vertical scale lines are engraved on the upper surface of the detection plate 3, and sealing strips 4 are fixedly connected to the outer walls of the two ends of the two detection plates 3 close to each other. The setting of the scale lines facilitates the measurement and calculation of the spread of fly ash slurry, and the setting of the sealing strips 4 can effectively prevent the fly ash slurry from leaking into the recovery box 2, effectively ensuring the accuracy of the detection data; both detection plates 3 are slidably sleeved outside the rotating rod 5, and the detection plates 3 start to rotate into the recovery box 2 under the action of the moving rod 6, further enabling the fly ash slurry to enter the recovery box 2 for recovery after the detection is completed, effectively avoiding the waste of resources. An outlet 14 is provided on the outer wall of the recovery box 2, and a sealing plug is installed inside the outlet 14. The setting of the outlet 14 enables the fly ash slurry inside the recovery box 2 to be discharged after a certain amount is filled;

[0026] Refer to Figure 1 , 4 , 5, 6 and Figure 7, two symmetrically distributed rotating rods 5 are installed at the upper end of the recycling bin 2. Moving rods 6 are respectively installed on the lower surfaces of the two detection plates 3, and the two moving rods 6 are symmetric to each other. One ends of the two groups of moving rods 6 are hinged to the lower surfaces of the detection plates 3, and the other ends of the two groups of moving rods 6 are hinged to a connecting rod 7. Under the action of the moving rods 6, the detection plates 3 can be operated to close and open. At this time, the fly ash slurry enters the interior of the recycling bin 2 as the detection plates 3 open, so that the fly ash slurry can be collected. A connecting rod 7 is installed at the lower end of the moving rod 6, and a linkage rod 8 is installed on the connecting rod 7. The linkage rod 8 is hinged to the connecting rod 7. By starting the motor 9, the motor 9 drives the linkage rod 8 to start rotating. Further, under the action of the connecting rod 7, the linkage rod 8 drives the two groups of moving rods 6 to move, and finally the collection of the fly ash slurry can be completed, effectively improving the utilization rate of the fly ash slurry. The other end of the linkage rod 8 is installed with a motor 9. An installation plate 10 is installed on the inner wall of the lower end of the recycling bin 2, and the motor 9 is installed on the outer wall of the installation plate 10. A sliding rod 11 is installed at the upper end of the recycling bin 2, and a plurality of uniformly distributed brushes 12 are fixedly connected to the lower surface of the sliding rod 11. A pull rod 13 is fixedly connected to the front end of the sliding rod 11;

[0027] Refer to Figure 1 and Figure 8 , two symmetrically distributed electric push rods 19 are installed on the upper surface of the bottom plate 1, and connecting blocks 18 are fixedly connected to the upper ends of the two electric push rods 19. A connecting sleeve 17 is fixedly connected between the two connecting blocks 18, and a dispersion pipe 15 is installed inside the connecting sleeve 17. The upper end of the dispersion pipe 15 is communicated with a feed hopper 16.

[0028] Working principle of the utility model: When starting the detection of the slump flow of fly ash slurry, first introduce the fly ash slurry from the feed hopper 16. Under the action of the dispersion pipe 15, the fly ash slurry will be evenly dispersed onto the detection plates 3 at different positions. The initial position of the lower end of the dispersion pipe 15 is closely attached to the upper end of the detection plate 3. When starting the detection, the electric push rod 19 can be started. Under the action of the connecting block 18 and the connecting sleeve 17, it will drive the dispersion pipe 15 to start moving slowly upward, which will further cause the fly ash slurry to start spreading slowly on the detection plate 3. After a period of time when the spreading of the fly ash slurry ends, the value on the detection plate 3 can be read. When the slump flow detection test of the fly ash slurry is completed, the motor 9 can be started. The motor 9 drives the two groups of moving rods 6 to start moving through the linkage rod 8 and the connecting rod 7. Further, the two groups of detection plates 3 will start to rotate slowly downward under the action of the moving rods 6. At this time, the fly ash slurry on the upper surface of the detection plate 3 will slowly flow into the interior of the recovery box 2. After all the fly ash slurry has flowed into the interior of the recovery box 2, start the motor 9 again to restore the two groups of detection plates 3 to the initial closely attached position. Then push the sliding rod 11 so that the multiple brushes 12 at the lower end of the sliding rod 11 can clean the residual fly ash slurry on the upper surface of the detection plate 3. Also, because there is a gap between the left side of the detection plate 3 and the left inner wall of the recovery box 2, the residual fly ash slurry can enter the recovery box 2 from the gap, thus completing the recovery work of the fly ash slurry.

[0029] The above is only the preferred embodiment of the utility model and is not intended to limit the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
