Description

Technical Field

[0001] The utility model relates to the technical field of gypsum board detection, in particular to a phosphogypsum board hardness detection device. Background Art

[0002] Phosphogypsum is typically grayish black or grayish white, with a lighter color, sometimes white. The primary phase of phosphogypsum is calcium sulfate dihydrate, and its crystals can occur in four forms: needle-shaped, monodisperse plate-shaped, polycrystalline, and dense, with plate-shaped crystals being the predominant. Phosphogypsum is primarily used in agriculture, industry, and construction. The technology used to produce building materials using phosphogypsum is relatively mature and has promising development prospects both domestically and internationally. Phosphogypsum is used to produce building materials such as gypsum board. After the gypsum board is produced, it must be hardness tested to see if the test results meet the relevant standards. If the phosphogypsum board meets the relevant standards, it is qualified and can be released to the market.

[0003] The existing gypsum board hardness tester manually adds a counterweight to the upper end of the guide column, so that the measuring steel ball at the lower end of the guide column is subjected to force to squeeze the surface of the gypsum board. The squeezing time is also specified. The timing starts from the placement of the counterweight to form a hemispherical pit. The depth of the hemispherical pit is then measured, and the hardness data is calculated based on the weight and depth.

[0004] However, when testing the hardness of gypsum boards, it is easy for fragments to remain on the testing equipment, and the testing equipment lacks a cleaning mechanism. As a result, the fragments remaining during the test not only affect the subsequent testing of other gypsum boards, but are also inconvenient for staff to clean up, seriously affecting the testing efficiency of the gypsum boards and failing to meet the use requirements. Therefore, a phosphogypsum board hardness testing device is proposed to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the utility model provides a phosphogypsum board hardness testing device, which has the advantages of strong practicality and easy cleaning of residual fragments during testing, solving the problem of inconvenience in cleaning gypsum board fragments remaining on the testing equipment.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a device for testing the hardness of a phosphogypsum board, comprising a test bench, a mounting bracket fixedly mounted on the outside of the test bench, and a testing device mounted on the mounting bracket for testing the hardness of the phosphogypsum board, the testing device comprising a hydraulic cylinder fixedly mounted on the mounting bracket, a mounting plate detachably mounted on the output end of the hydraulic cylinder, and a hardness testing head fixedly mounted on the lower surface of the mounting plate, the lower surface of the mounting plate being provided with an abutment structure, and the outside of the test bench being provided with a cleaning mechanism;

[0009] Furthermore, the hardness test head is located in the middle of the lower surface of the mounting plate, and the number of the abutting structures is four, and the four abutting structures are distributed in a rectangular shape on the lower surface of the mounting plate.

[0010] Furthermore, the dust collection structure includes a dust collection box fixedly mounted on the side of the vertical plate away from the test bench, a suction pipe arranged outside the mounting base, a plurality of suction nozzles fixedly connected to the lower surface of the suction pipe, and a connecting pipe fixedly connected between the dust collection box and the suction pipe.

[0011] Furthermore, a clamp for fixing the suction pipe is installed on the outside of the mounting seat through bolts, the connecting pipe is a hose, and a partition is slidably installed inside the dust collection box.

[0012] Furthermore, a collection box extending outward is slidably provided on the right side of the test bench, and a feeding port adapted to the collection box is provided on a side of the test bench away from the vertical plate.

[0013] Furthermore, a mounting groove communicating with the outside is provided on the right side of the test bench, and the mounting groove is communicated with the feed opening, and a connector for installing the collection box is installed in the mounting groove.

[0014] Furthermore, two guide rods symmetrically arranged and passing through the interior of the mounting frame are fixedly mounted on the upper surface of the mounting plate, and a support frame for support is welded to the lower surface of the test bench.

[0017] 2. The phosphogypsum board hardness testing device drives the hardness test head downward through the dynamic hydraulic cylinder.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-3 A device for testing the hardness of a phosphate gypsum board comprises a test bench 1, a mounting frame 2 fixedly mounted on the outside of the test bench 1, and a detection device mounted on the mounting frame 2 for detecting the hardness of the phosphate gypsum board. The detection device comprises a hydraulic cylinder 3 fixedly mounted on the mounting frame 2, a mounting plate 4 detachably mounted on the output end of the hydraulic cylinder 3, and a hardness testing head 5 fixedly mounted on the lower surface of the mounting plate 4. The lower surface of the mounting plate 4 is provided with an abutment structure, which comprises an elastic telescopic rod 6, a pressure block 7 fixedly mounted on the bottom end of the elastic telescopic rod 6, and a mounting block 8 welded to the top end of the elastic telescopic rod 6 and fixed to the lower surface of the mounting plate 4. The mounting block 8 is fixed to the mounting plate 4 by bolts, so that the abutment structure can be adjusted in displacement to better fix phosphate gypsum boards of different sizes.

[0024] It should be noted that the hardness test head 5 is located in the middle of the lower surface of the mounting plate 4. It has four abutment structures, distributed in a rectangular pattern across the lower surface of the mounting plate 4. A pressure sensor is installed within the hardness test head 5, and a controller is fixedly mounted on the exterior of the mounting frame 2. The installation of the pressure sensor and controller facilitates the display of the pressure measured by the hardness test head 5. Pressure sensors are conventional technology known in the art, so their specific structure and operating principles will not be elaborated upon in this article.

[0025] Two symmetrical guide rods are fixed to the upper surface of the mounting plate 4 and extend through the interior of the mounting frame 2. A support frame 21 is welded to the lower surface of the test bench 1. The installation of the two guide rods allows the mounting plate 4 to move linearly up and down, improving the hardness test of the phosphogypsum board.

[0026] In this embodiment, a cleaning mechanism is provided on the exterior of the test bench 1; the cleaning mechanism comprises a riser 9 fixedly mounted on the upper surface of the test bench 1, an electric push rod 10 fixedly mounted on the riser 9, a mounting base 11 fixedly mounted on the output end of the electric push rod 10, a cleaning brush 12 bolted to the lower surface of the mounting base 11, and a dust collection structure mounted on the riser 9 and the mounting base 11. The dust collection structure comprises a dust collection box 13 fixedly mounted on the side of the riser 9 away from the test bench 1, a suction pipe 14 provided on the exterior of the mounting base 11, a plurality of suction nozzles 15 fixedly connected to the lower surface of the suction pipe 14, and a connecting pipe 16 fixedly connected between the dust collection box 13 and the suction pipe 14.

[0027] In this embodiment, a clamp 17 is bolted to the exterior of the mounting base 11, securing the suction tube 14. The connecting tube 16 is a flexible tube, and its length matches the telescopic range of the electric actuator 10. A partition is slidably mounted within the dust collection box 13. The dust collection box 13 consists of a housing and a dust collection blower, which is mounted on the side of the housing away from the connecting end 16. The partition acts as a barrier to prevent debris from entering the dust collection blower.

[0028] In addition, when the hydraulic cylinder 3 is not working, the height of the hardness test head 5 is higher than the mounting seat 11, which will not affect the displacement of the mounting seat 11 driven by the electric push rod 10, thereby not affecting the cleaning of the cleaning brush 12.

[0029] A collection box 18 is slidably mounted on the right side of the test bench 1, extending outward. A discharge port 19, adapted for the collection box 18, is provided on the side of the test bench 1 away from the riser 9. A mounting slot, communicating with the outside, is also provided on the right side of the test bench 1. The mounting slot is connected to the discharge port 19, and a connector 20 for mounting the collection box 18 is mounted within the mounting slot. The connector 20 has a structure similar to that of a drawer in the prior art, enabling the collection box 18 to be removed from the mounting slot.

[0030] When this embodiment is in use, the electric push rod 10 is started, the cleaning brush 12 is displaced to push the fragments toward the lower feeding port 19 and discharge them into the collection box 18 from the lower feeding port 19. At the same time, the dust collection box 13 is started, the suction nozzle 15 sucks in the dust and transports it through the suction pipe 14 and the connecting pipe 16 to the dust collection box 13 for storage, thereby avoiding the generation of large dust when cleaning the fragments.

[0031] The working principle of the above embodiment is:

[0032] During use, the phosphogypsum board is placed under the hardness testing head 5, and the controller is operated to start the hydraulic cylinder 3 to drive the hardness testing head 5 to move downward. At this time, the pressure block 7 first contacts the phosphogypsum board and cooperates with the deformation of the elastic telescopic rod 6 to press it tightly, thereby fixing the phosphogypsum board, so that the hardness testing head can be tested stably. The hardness test of the phosphogypsum board can be performed by the pressure sensor on the hardness testing head 5 in conjunction with the controller for numerical display. After the test is completed, the phosphogypsum board is removed, the electric push rod 10 is started, and the cleaning brush 12 is displaced to push the fragments to the lower feeding port 19 and discharge them into the collection box 18 from the lower feeding port 19. At the same time, the dust collection box 13 is started, and the suction nozzle 15 sucks in dust and transports it to the dust collection box 13 for storage through the suction pipe 14 and the connecting pipe 16 to avoid generating large dust when cleaning the fragments.

[0033] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the present invention is controlled by the controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.
