Description

Technical Field

[0001] The utility model relates to the technical field of shield machine quarrying and screening, in particular to a slag and stone separation and collection device. Background Art

[0002] The description in this section merely provides background information related to the disclosure of the present utility model and does not constitute prior art.

[0003] In the field of slurry shield technology, the slurry pipeline of the shield machine is used to transport slurry and slag and other devices generated during the excavation process. Therefore, there will be slag and rocks of different sizes in the slurry discharge pipeline. However, the slurry pump in the slurry pipeline has limited passing capacity, and the slag and rocks of different sizes generated during the excavation process cannot pass through completely. Therefore, there will be a certain amount of slag stuck in the pipe or slag stuck in the pump. In order to avoid such pipe sticking and thus affecting production safety and stability, screening devices and quarrying devices are usually installed in front of the slurry discharge pipeline to separate the slag and rocks with too large a diameter in advance, and prevent the slag and rocks that are too large from entering the slurry discharge pipeline, ensuring the safe operation of the shield machine and reducing the situation of downtime for maintenance.

[0004] At present, the screening and quarrying devices used in the industry mainly include two categories. One is the active screening device, which uses centrifugal force or stirring to achieve the purpose of screening. However, in the construction environment of the shield machine, the conditions are generally harsh. The power structure in the active screening device is easily stuck by slag, causing damage to the power shaft or leakage of the pipeline seal. In addition, it is not easy to find a maintenance technician during the construction process, which will affect the overall progress of the construction. The second type is the non-powered type. The non-powered type does not have the ability of active screening, so the structural design of the passive screening is very critical. Specifically, the screening structure used in the existing passive screening device is too simple, and it is easy to cause the filter structure to be blocked. It needs to be shut down for maintenance and cleaning of slag frequently, resulting in low overall construction efficiency; and it does not have the ability to use different screening degrees for different strata for screening.

[0005] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solutions of the utility model and for the convenience of understanding by those skilled in the art. It cannot be considered that the above technical solutions are well known to those skilled in the art simply because these solutions are described in the background technology section of the utility model.

There is no specific restriction on the structural setting method of the multiple stone quarrying chambers 14.

[0050] In a specific embodiment, Figure 1 and Figure 7 As shown, the filter plate mechanism 2 has at least one first filter plate 21 and at least one second filter plate 22 connected to each other, at least one first filter plate 21 is arranged at one end close to the slurry inlet 12, and at least one second filter plate 22 is arranged at one end close to the quarrying cavity 14.

[0051] The slag and rock separation and collection device provided by the utility model can replace the grille models of the first filter plate 21 and the second filter plate 22 according to actual filtering needs through the arrangement of the first filter plate 21 and the second filter plate 22; at the same time, the structural design of the two filter plates ensures the flow capacity of the mud and also ensures that the filtering capacity of the filter plate mechanism 2 is not affected, thereby avoiding clogging by slag and rock.

[0052] Specifically, in the present embodiment, a first filter plate 21 and a second filter plate 22 are combined to form the filter plate mechanism 2. In other embodiments, a plurality of first filter plates 21 and a plurality of second filter plates 22 may form the filter plate mechanism 2. There is no specific restriction on the number of the first filter plates 21 and the second filter plates 22. In the present embodiment, one end of a first filter plate 21 is arranged close to the slurry inlet 12. The first filter plate 21 is responsible for the main filtering and is responsible for filtering out most of the slag in the mud. In other embodiments, two first filter plates 21 may be symmetrically arranged in the filter chamber 11, and the slurry inlet 12 is arranged above the mutual connection between the two first filter plates 21. There is no specific restriction on this. In the present embodiment, the number of the second filter plate 22 is one, and one end of the second filter plate 22 is connected to the first filter plate 21. The second filter plate 22 is responsible for filtering the mud overflowing from the first filter plate 21, and also provides the mud filtered out from the first filter plate 21. The second filter plate 22 in this embodiment is detachably connected to the first filter plate 21, that is, the first filter plate 21 and the second filter plate 22 can select different grille models according to the specifications of the slag to be filtered and screened, and the selectable grille models include square hole filter grilles, circular hole filter grilles, diamond hole filter grilles, etc., and there is no specific restriction on the grille model used for the filter plate; in other embodiments, the first filter plate 21 is fixedly connected to the second filter plate 22, and the grille model can be replaced as a whole, and there is no specific restriction on the connection relationship between the first filter plate 21 and the second filter plate 22; in this embodiment, the inclination angle of the second filter plate 22 toward the quarrying cavity 14 is different from the inclination angle of the first filter plate 21 toward the quarrying cavity 14, so as to facilitate the rolling of the filtered slag; in other embodiments, the inclination angle of the second filter plate 22 toward the quarrying cavity 14 is the same as the inclination angle of the first filter plate 21 toward the quarrying cavity 14, and there is no specific restriction on this.

[0053] In a specific embodiment, Figure 1 , Figure 2 and Figure 7 As shown, the first filter plate 21 and the second filter plate 22 are both one, one end of the first filter plate 21 is connected to the inner wall of the filter slurry bin 1, and the other end is connected to the second filter plate 22, and the inclination angle of the first filter plate 21 toward the quarrying cavity 14 is smaller than the inclination angle of the second filter plate 22 toward the quarrying cavity 14.

[0054] The slag separation and collection device provided by the utility model is convenient for the filtered slag to roll off the filter plate mechanism 2 more easily by setting the inclination angle of the first filter plate 21 toward the quarrying cavity 14, and the inclination angle of the second filter plate 22 toward the quarrying cavity 14, so as to avoid the slag to accumulate on the filter plate mechanism 2. At the same time, since the first filter plate 21 undertakes the main filtering task, the inclination angle of the first filter plate 21 toward the quarrying cavity 14 is smaller than the inclination angle of the second filter plate 22 toward the quarrying cavity 14, so that most of the mud can be filtered on the first filter plate 21. At the same time, the slag filtered out on the first filter plate 21 can gradually roll onto the second filter plate 22 under the scouring of the mud, and accelerate to roll into the quarrying cavity 14 on the second filter plate 22.

[0055] Specifically, the first filter plate 21 and the second filter plate 22 in this embodiment are both one, and one end of the first filter plate 21 connected to the inner wall of the filter pulp bin 1 is arranged near the pulp inlet 12, and one end of the second filter plate 22 is arranged toward the quarrying cavity 14. In other embodiments, one end of the second filter plate 22 can also be connected to a plate of the filter pulp bin 1 isolated between the quarrying cavity 14 and the pulp outlet cavity 112, and there is no specific limitation to this; the inclination angle of the first filter plate 21 toward the quarrying cavity 14 is the angle between the first filter plate 21 and the horizontal plane, and the inclination angle of the second filter plate 22 toward the quarrying cavity 14 is the angle between the second filter plate 22 and the horizontal plane.

In other embodiments, the plate changing port 15 can also be arranged at the top or front of the filter pulp bin 1 to achieve convenient replacement as a specific requirement, and the opening shape of the plate changing port 15 is matched with the position of the plate change, and the specific structural form of the plate changing port 15 is not limited; further, in this embodiment, Figure 7 As shown, handles 23 are provided on the side of the first filter plate 21 and the side of the second filter plate 22, so as to facilitate replacement from the side of the first filter plate 21 or the side of the second filter plate 22 when extracting.

[0060] The filter slurry bin 1 provided by the utility model is convenient for sealing the plate changing port 15 by arranging a sealing baffle 3 at the plate changing port 15, thereby preventing mud and slag from overflowing the filter chamber 11 from the plate changing port 15. At the same time, the sealing protrusion 31 of the sealing baffle 3 is also arranged to be sealed and clamped with the filter plate mechanism 2, so that the sealing baffle 3 can fix the filter plate mechanism 2, thereby preventing the filter plate mechanism 2 from vibrating and shifting due to the impact of mud in the filter chamber 11.

[0061] Specifically, the shape of the sealing baffle 3 is matched with the shape of the plate changing port 15. In this embodiment, the sealing baffle 3 is a combination of two-stage rectangular baffles, and the sealing baffle 3 can be disassembled into two baffles.

[0062] In a specific embodiment, Figure 1 and Figure 8 As shown, the sealing stopper 3 comprises a first stopper 32 and a second stopper 33 which are detachably connected. The first stopper 32 is sealed and clamped with the first filter plate 21 , and the second stopper 33 is sealed and clamped with the second filter plate 22 .

[0063] The sealing baffle 3 provided by the utility model realizes the effect of separate opening and replacement for the first filter plate 21 and the second filter plate 22 by setting it as a detachably connected first baffle 32 and a second baffle 33, thereby avoiding the need to remove the entire sealing baffle 3 when only the first filter plate 21 or the second filter plate 22 is replaced, resulting in a problem of low overall replacement efficiency; and also avoids the problem of increased risk of structural damage caused by multiple disassembly of the sealing baffle 3.

[0065] In a specific embodiment, Figures 1 to 6 As shown, the filter pulp bin 1 is further provided with a quarrying opening 16 and a first monitoring device 4 . The quarrying opening 16 is connected to at least one quarrying cavity 14 . The first monitoring device 4 is arranged in the quarrying cavity 14 .

[0066] The filter pulp bin 1 provided by the utility model realizes monitoring of the amount of slag contained in the quarrying cavity 14 through the setting of the quarrying opening 16 and the first monitoring device 4, so as to avoid the problem of excessive accumulation of slag in the quarrying cavity 14 leading to difficulty in cleaning. Specifically, the first monitoring device 4 in this embodiment is arranged on the inner wall of the filter pulp bin 1, and the height of the first monitoring device 4 arranged in the filter pulp bin 1 is the warning height of the quarrying cavity 14, and the quarrying opening 16 is arranged at the lower part of the filter pulp bin 1 and is connected to the quarrying cavity 14; when the first monitoring device 4 detects that the accumulation height of the slag reaches the warning height, the first monitoring device 4 issues an alarm, and at this time, the construction personnel can open the quarrying opening 16 for quarrying.

[0067] In a specific embodiment, Figures 1 to 4 As shown, a first flushing port 171 is further provided at the upper portion of the filter pulp bin 1 , and the opening direction of the first flushing port 171 is arranged toward the end of the filter plate mechanism 2 close to the pulp inlet 12 .

[0068] The filter pulp bin 1 provided by the utility model can realize that when too much slag is accumulated on the filter plate mechanism 2 and the slag cannot be actively cleaned, the first flushing port 171 is used to inject liquid into the pulp inlet cavity 111 for jet flow, so as to flush the slag accumulated on the filter plate mechanism 2 into the quarrying cavity 14, so as to realize the cleaning operation of the filter plate mechanism 2. Specifically, the first flushing port 171 in this embodiment is arranged on the inner wall of the upper part of the filter pulp bin 1, and the opening direction of the first flushing port 171 is arranged toward the end of the first filter plate 21 close to the pulp inlet 12, so as to maximize the impact force and avoid the slag that cannot be flushed; in other embodiments, the opening direction of the first flushing port 171 can also be arranged toward the middle position of the first filter plate 21, and there is no specific limitation on this.

[0069] In a specific embodiment, Figures 2 to 4 As shown, a second monitoring device 5 is further provided on the upper portion of the filter pulp bin 1 , and the second monitoring device 5 is arranged close to the end of the filter plate mechanism 2 away from the quarrying cavity 14 .

[0070] The filter pulp bin 1 provided by the utility model is provided with a second monitoring device 5 to monitor whether the slag and stone accumulated on the filter plate mechanism 2 has reached the warning amount. If the amount of slag and stone accumulated on the filter plate mechanism 2 is too much, it will affect the normal screening function of the slag and stone separation and collection device. Specifically, the second monitoring device 5 is installed on the inner wall of the upper part of the filter pulp bin 1, and the height of the second monitoring device 5 set on the filter pulp bin 1 is the warning height of the pulp inlet cavity 111; when the second monitoring device 5 detects that the accumulation height of the slag and stone reaches the warning height of the pulp inlet cavity 111, the second monitoring device 5 issues an alarm, and at this time, the construction personnel can use the flushing port 17 to flush the slag and stone accumulated on the filter plate mechanism 2.

[0071] In a specific embodiment, Figure 3 and Figure 6 As shown, an observation window 18 and an inspection port 19 are further provided at the lower portion of the slurry filter bin 1 . The observation window 18 is provided corresponding to the slurry discharge chamber 112 , and the inspection port 19 is communicated with the slurry discharge chamber 112 .

[0072] Because the mud contains some fine slag, it will settle at the bottom of the cavity under the influence of gravity. Long-term accumulation will gradually accumulate into an excessively high sand layer. The filter slurry bin 1 provided by the utility model is convenient for checking the accumulation of the sand layer in the slurry discharge cavity 112 at any time by setting an observation window 18 and an inspection port 19, so as to avoid the excessively accumulated sand layer affecting the normal slurry discharge of the slurry discharge port 13. Specifically, the observation window 18 of this embodiment is arranged at the lower part of the filter slurry bin 1, and the observation window 18 is a closed observation window 18 to avoid leakage of mud. The inspection port 19 is arranged on the side of the lower part of the filter slurry bin 1, so that the construction personnel can observe the sand layer in the slurry discharge cavity 112 and stop the machine in time to open the inspection port 19 for inspection.
