Description

Technical Field

[0001] This utility model relates to the field of shield tunneling mud sample preparation, specifically a drying, curing and crushing device for shield tunneling mud sample preparation. Background Technology

[0002] Shield tunneling mud is a special liquid mixture used in shield tunnel construction. It serves multiple functions, including supporting the excavation face, cooling the cutting tools, removing soil, and maintaining tunnel stability. It typically consists of water, clay, chemical additives, and other fillers (such as bentonite, lime, and other polymers). When preparing shield tunneling mud samples, the samples need to be dried, solidified, and broken down. This helps in better analyzing its mineral composition and physical properties, and also provides finer, more uniform samples for experiments.

[0003] However, existing shield tunneling mud cannot be quickly removed from the inside of the tunnel body after drying and solidification, which can easily affect the efficiency of subsequent crushing work. In addition, most existing crushing methods only use single crushing, resulting in poor crushing effect and affecting the thickness detection of shield tunneling mud samples.

[0004] Therefore, those skilled in the art have provided drying, solidification, and crushing devices for shield tunneling mud sample preparation to solve the problems mentioned in the background art. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-5 This utility model provides a technical solution for a drying, curing, and crushing device for shield tunneling mud sample preparation: it includes a drying and curing box 1 and a crushing box 3 set below the drying and curing box 1. The front surface of the drying and curing box 1 is provided with a box door 2. The rear surface of the box door 2 is connected to a placement plate 21 inside the drying and curing box 1. A connecting rod 71 is provided through the rear surface of the drying and curing box 1. The rear end of the connecting rod 71 is connected to the connecting plate 7. A heating box 6 is provided on the upper surface of the drying and curing box 1. A heating pipe 62 is provided inside the heating box 6. An exhaust pipe 64 is symmetrically arranged on the lower surface of the heating box 6. The lower end of the exhaust pipe 64 is connected to a U-shaped pipe 65. A spray hole 651 is opened on the inner side of the U-shaped pipe 65.

[0018] In this embodiment: a sample preparation tank 22 for storing shield tunneling mud is provided on the upper surface of the placement plate 21. The shield tunneling mud is poured into the sample preparation tank 22. The drying and curing box 1 is closed by moving the box door 2, so that the shield tunneling mud is dried and cured inside the drying and curing box 1. At the same time, the heating pipe 62 inside the heating box 6 can heat the incoming air, thereby heating the inside of the drying and curing box 1 to achieve drying and curing.

[0019] Please refer to this carefully. Figure 4As shown, the upper surface of the crushing box 3 is provided with a feed inlet 31, and a first motor 4 is symmetrically arranged on the outer side of the crushing box 3. The drive end of the first motor 4 is connected to the first crushing roller 41. A second motor 5 is also symmetrically arranged on the front surface of the crushing box 3. The drive end of the second motor 5 is connected to the second crushing roller 51 inside the crushing box 3. This arrangement allows the first crushing roller 41 to rotate and crush the dried and solidified shield slurry by the operation of the first motor 4, and the second crushing roller 51 can be rotated by the second motor 5 to crush the slurry again, thereby improving its crushing effect.

[0020] Please refer to this carefully. Figure 1 , Figure 2 and Figure 5 As shown, the front end of the connecting rod 71 is fixed to the rear surface of the box door 2, and the rear end of the connecting rod 71 is fixed to the front surface of the connecting plate 7. A cylinder 72 is also installed on the rear surface of the drying and curing box 1, and the telescopic end of the cylinder 72 is connected to the middle position of the front surface of the connecting plate 7.

[0021] In this embodiment: the operation of the cylinder 72 causes the connecting plate 7 to move back and forth behind the drying and curing box 1, and is guided by the connecting rod 71. This facilitates the removal of the dried and cured shield slurry from the sample preparation groove 22 on the placement plate 21, thereby facilitating subsequent crushing.

[0022] Please refer to this carefully. Figure 2 As shown, the upper surface of the heating box 6 is provided with an air inlet 61, and two sets of exhaust pipes 64 are symmetrically arranged on the lower surface of the heating box 6. The heating box 6 is also equipped with an exhaust fan 63. This arrangement utilizes the exhaust fan 63 inside the heating box 6 to allow external air to enter the heating box 6 through the air inlet 61 and be heated by the heating pipe 62 after entering, so as to facilitate the subsequent drying and curing of the shield tunneling slurry in the drying and curing box 1. The hot air entering the drying and curing box 1 can be discharged outward through the exhaust pipe provided on its outside, and the exhaust pipe can be equipped with a valve for control.

[0023] Please refer to this carefully. Figure 4 As shown, a feeding plate 32 is inclinedly arranged on the inner side of the crushing box 3. One end face of the feeding plate 32 is positioned above the second crushing roller 51. This arrangement allows the feeding plate 32 to be inclined so that after the first crushing roller 41 crushes the dried and solidified shield slurry, it can be fed above the two second crushing rollers 51. In this way, the shield slurry can be crushed again by the two second crushing rollers 51.

[0024] Please refer to this carefully. Figure 1As shown, a recovery chamber is provided on the lower surface of the crushing box 3, and a recovery frame is slidably installed inside the crushing box 3 below the recovery chamber. This arrangement utilizes the sliding of the recovery frame inside the recovery chamber to achieve the purpose of recovering and testing the crushed shield slurry.

[0025] In this embodiment: When using the drying, curing, and crushing device for shield tunneling mud sampling of this utility model, the shield tunneling mud sample to be sampled is poured into the sampling trough 22 opened on the placement plate 21. It should be noted that the mud level in the sampling trough 22 does not exceed the height of the sampling trough 22, so that there will be no leakage. Furthermore, a baffle can be set on the inner side of the sampling trough 22 to block the mud. After extraction, there will be a gap between the dried and cured mud and the sampling trough 22, which facilitates the removal of the dried shield tunneling mud sample. During drying and curing, the device is activated... When the cylinder on the rear surface of the drying and curing chamber 1 is activated, the connecting plate 7 moves backward. During this movement, the door 2 moves into the drying and curing chamber 1 via the connecting rod 71 to seal it. At this time, the external air is drawn in by the exhaust fan 63 inside the heating chamber 6 and heated through the heating pipe 62. After heating, the air enters the U-shaped pipe 65 through the exhaust pipe 64 and is finally sprayed out through the spray hole 651 to dry and cure the shield tunneling mud inside the drying and curing chamber 1. Temperature sensors can be installed inside the drying and curing chamber 1 and the heating chamber 6 to monitor the temperature.

[0026] Simultaneously, after drying and curing, the cylinder can be used to move the door 2 away from the drying and curing box 1, so that the shield slurry in the sample preparation groove 22 on the placement plate 21 can be taken out. After taking it out, the first motor 4 and the second motor 5 are started, and the removed shield slurry can enter the crushing box 3 from the feed port 31. After entering, it will be crushed by two first crushing rollers 41. After crushing, the shield slurry will fall between two second crushing rollers 51 through the feed plate 32 for a second crushing. This achieves the purpose of efficient crushing of the shield slurry. After crushing, the shield slurry will fall into the recycling box for recycling, so as to facilitate subsequent testing.

[0027] All electrical devices used in this invention are existing and known, and are connected to an external main controller and power supply. The main controller can be a conventional and known device such as a computer, and can be purchased and used directly on the market. Its structure, circuit and control principle are all existing and known technologies. Therefore, the structure, circuit and control principle of the device are not described in detail here.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
