Description

Technical Field

[0001] The invention relates to desert and saline-alkali land treatment, and in particular to a desert and saline-alkali land treatment system and method. Background Art

[0002] Desertification and salinization are serious environmental challenges facing the world today, which seriously affect ecological balance, land resource utilization, agricultural production and human life. Due to the sparse vegetation, poor soil water and fertilizer retention capacity, and frequent wind and sand activities in desert areas, the land is gradually degraded and its usable value is extremely low; while salinization has too high salt content in the soil, which inhibits the normal growth of plants, making large areas of land barren and crop yields sharply reduced, posing a major threat to food security.

[0003] Traditional desert and saline-alkali land management methods have many limitations. For example, in desert management, simple afforestation is often restricted by factors such as water shortage and insufficient soil fertility, with low survival rates and difficulty in forming stable vegetation communities. Physical sand control measures such as setting up sand barriers can slow down the flow of wind and sand to a certain extent, but the long-term effect on improving soil quality and ecological environment is not ideal. In the management of saline-alkali land, commonly used water conservancy improvement methods (such as irrigation and drainage) consume a large amount of freshwater resources, and over time, soil salt return is more common. Chemical improvement methods may introduce new chemical substances, which may have a potential negative impact on the soil ecological environment, and the cost is high, making it difficult to promote and apply on a large scale.

[0004] Gangue is a solid waste generated during coal mining and washing. Its large accumulation not only occupies land resources, but also causes problems such as dust pollution, soil pollution and groundwater pollution to the surrounding environment. However, gangue itself has some characteristics that make it have the potential to be used in desert and saline-alkali land management. Gangue contains a certain amount of mineral elements such as silicon, aluminum, iron, calcium, magnesium, etc. These elements can provide nutrients to the soil and improve the fertility of the soil after proper treatment; its particle structure is relatively stable, which can increase the porosity of the soil, improve the air permeability and water permeability of the soil, and help the penetration and retention of water, thereby improving the poor soil physical properties of deserts and saline-alkali lands to a certain extent.

[0005] Therefore, those skilled in the art are committed to developing a system and method for utilizing coal gangue to control desertification and coal gangue. Summary of the invention

[0010] Further, the towing hose is installed on one side of the trenching and spreading vehicle through a swivel joint.

[0011] Furthermore, the remote transmission hard pipe system is provided with a flushing pipe in parallel beside the solid-liquid mixed fluid transmission pipe, and a flushing branch pipe connecting the solid-liquid mixed fluid transmission pipe and the flushing pipe is provided at a certain interval between the two, and a flushing valve is provided on the flushing branch pipe.

[0012] Furthermore, the flushing valve is equipped with a driving mechanism that can realize instantaneous movement of the valve core: the driving mechanism includes a motor; the output gear of the motor cooperates with the large gear; the outer end of the coil spring is fixed on the large gear; the inner end of the coil spring is fixedly connected to the shaft of the worm; the worm cooperates with the pinion; one end of the pinion is connected to the valve core, and the other end is connected to the rocker arm; the rocker arm has four rod heads spaced 90° apart; the driving mechanism also includes at least one limit block, on which a limit groove for accommodating the rod head is provided; the limit groove has front and rear protrusions on both sides, and the height of the rear protrusion is greater than that of the front protrusion.

[0013] The present invention also provides a method for treating deserts and saline-alkali land, comprising the following steps:

[0014] (1) preparing coal gangue near the coal mine into a coal gangue solid-liquid mixture;

[0015] (2) Transporting the solid-liquid mixture of coal gangue to deserts or saline-alkali lands;

[0016] (3) Spreading coal gangue powder on the surface of desert or saline-alkali land;

[0017] In step (2), a remote transport hard pipe system is used to remotely transport the coal gangue solid-liquid mixture. In step (3), a hose is used to connect the hard pipe and the pressure-retracting and unwinding device, and the hose is connected to the trenching and spreading vehicle as a towing hose.

[0018] Furthermore, in step (2), a flushing pipe is arranged in parallel beside the solid-liquid mixed fluid conveying pipe in the remote conveying hard pipe system, and a flushing branch pipe connecting the solid-liquid mixed fluid conveying pipe and the flushing pipe is arranged at a certain interval between the two, and a flushing valve is arranged on the flushing branch pipe; the flushing valve is equipped with a driving mechanism that can realize instantaneous action of the valve core: the driving mechanism includes a motor; the output gear of the motor cooperates with the large gear; the outer end of the coil spring is fixed on the large gear; the inner end of the coil spring is fixedly connected to the shaft of the worm; the worm cooperates with the pinion; one end of the pinion is connected to the valve core, and the other end is connected to the rocker; the rocker has four rod heads spaced 90° apart; the driving mechanism also includes at least one limit block, and the limit block is provided with a limit groove for accommodating the rod head; the limit groove has a front protrusion and a rear protrusion on both sides, and the height of the rear protrusion is greater than the front protrusion.

[0019] Furthermore, in step (3), during spreading, the trenching and spreading vehicle performs reciprocating operation between the upper working mark m and the lower working mark n along the working direction w; at the same time, the reel of the pressure-reeling and rewinding device rotates so that the length of the towing hose and the stroke of the trenching and spreading vehicle are kept synchronized; in addition, the towing hose is installed on one side of the trenching and spreading vehicle through a swivel joint.

The present invention can be embodied in many different forms of embodiments, and the protection scope of the present invention is not limited to the embodiments mentioned in the text.

[0048] The use of coal gangue to control deserts and coal gangue mainly includes three steps: preparing coal gangue into a coal gangue solid-liquid mixture near the coal mine, transporting the coal gangue solid-liquid mixture to the desert or saline-alkali land remotely, and spreading coal gangue powder on the surface of the desert or saline-alkali land.

[0049] Preparation of solid-liquid mixture of coal gangue

[0050] like Figure 1As shown, in this embodiment, in the first workshop 100, the excavator 104 digs the gangue from the gangue pile 101 and puts it into the crusher 103. The crusher 103 crushes the gangue to obtain the gangue powder pile 102. The excavator 104 adds the gangue powder to the upper bin 106. The gangue powder in the upper bin 106 is then transported to the storage tank 111 through the conveyor belt 107. At the same time, a plurality of reagents 105 are transported to the reaction tank 110 for mixed reaction and then transported to the storage tank 111. The groundwater collected by the deep water well lifting equipment 108 is lifted to the reservoir 109. The water in the reservoir 109 is transported to the storage tank 111 to form a solid-liquid mixture of gangue. In other embodiments, water can also have other sources, such as industrial water. A plurality of storage tanks 111 can be provided, and a stirring device can be provided in the storage tank. The first workshop 100 is preferably arranged near a coal mine. The coal gangue solid-liquid mixture prepared in the first workshop 100 is remotely transported to the second workshop 200 via a transport pump 112 and a transport pipe system 300 .

[0051] Long-distance transportation of solid-liquid mixture of coal gangue

[0052] In order to prevent the problem of sediment accumulation in the coal gangue solid-liquid mixture during long-distance transportation through the transportation pipe system 300, the present invention also provides a method as follows: Figure 2-5 The anti-deposition coal gangue solid-liquid mixed fluid transportation pipeline system and method shown in.

[0053] like Figure 2-3 As shown, according to the anti-deposition coal gangue solid-liquid mixed fluid conveying pipeline system of the present invention, a flushing pipe 2 is arranged next to the solid-liquid mixed fluid conveying pipe 1. The flushing pipe 2 is preferably arranged in parallel with the solid-liquid mixed fluid conveying pipe 1, and contains a fluid for flushing, generally water. A flushing branch pipe 3 is arranged at a certain interval between the solid-liquid mixed fluid conveying pipe 1 and the flushing pipe 2. A one-way stop valve 4 is arranged between the solid-liquid mixed fluid conveying pipe 1 and the flushing pipe 2. The one-way stop valve 4 is maintained in a normally closed state by a torsion spring 6. A flushing valve is arranged on the flushing branch pipe 3. In the embodiment shown in the figure, the flushing valve has a valve core 5, and the valve can be opened and closed by rotating the valve core 5 by 90°.

[0054] like Figure 4-5As shown, in order to ensure the impact of the flushing water flow, the present invention is equipped with a driving mechanism for the flushing valve that can realize the instantaneous action of the valve core 5. The driving mechanism includes a motor 7. The output gear 8 of the motor 7 cooperates with the large gear 9. The outer end of the coil spring 10 is fixed to the large gear 9. The inner end of the coil spring 10 is fixedly connected to the shaft of the worm 11. The worm 11 cooperates with the pinion 12. One end of the pinion 12 is connected to the valve core 5, and the other end is connected to the swing rod 13. In this embodiment, the swing rod 13 has four rod heads 21 spaced 90° apart. The driving mechanism also includes at least one limit block 14, but it is preferred that two limit blocks 14 are arranged symmetrically at 180° as in this embodiment. A limit groove 22 for accommodating the rod head 21 is provided on the limit block 14. The limit groove 22 is flanked by a front protrusion 15 and a rear protrusion 16, and the height of the rear protrusion 16 is greater than that of the front protrusion 15. The stopper 14 is telescopically mounted on the stopper seat 19 by a spring 18 and a screw knob 17. The compression degree of the spring 18 can be adjusted by the screw knob 17, thereby adjusting the elastic force that needs to be overcome to retract the stopper 14.

[0055] When flushing is required, the motor 7 rotates to drive the large gear 9 to rotate. When the large gear 9 rotates, the coil spring 9 is tightened and stored, and torque is applied to the worm 11 at the same time. The worm 11 transfers the torque to the swing rod 13 through the pinion 12. When the coil spring 9 stores power to generate torque sufficient to enable the rod head 21 to overcome the resistance of the rear protrusion 16 of the limit groove 22, the rod head 21 escapes from the limit groove 22, the swing rod 13 rotates 90°, and the rod head 14 overcomes the resistance of the front protrusion 15 and enters the limit again. At the same time, the pinion 12 drives the valve core 5 to rotate 90° as well, so that the valve core 5 opens quickly, so that the flushing water flow of the flushing pipe 2 flushes the one-way stop valve 4 into the solid-liquid mixed fluid delivery pipe 1 to form an impact water flow, and flushes the solid sediment therein. When the worm 11 rotates, the coil spring 9 is also released. When the motor 7 continues to rotate, the above process occurs again, and the rod head 14 rotates 90° again, so that the valve core 5 is closed. Due to the self-locking of the worm 11, the drive mechanism will not reverse. The rotation of the motor 7 is controlled by the controller and cleaned regularly. The controller is connected to the network and can be centrally controlled by a remote control room. The drive mechanism can be powered by a solar panel 20. The intermittent switching valves of multiple flushing branches 3 can flush the sediment in the conveying pipe without significantly affecting the proportion of the conveyed medium. The coal gangue solid-liquid mixed fluid conveying pipe 1 and the flushing pipe 2 of the conveying pipe system 300 are preferably hard pipes because they need to complete long-distance transmission tasks.

[0056] Spreading of solid-liquid mixture of coal gangue

[0057] Continue to see Figure 1 , see also Figure 6After the solid-liquid mixed fluid of coal gangue is remotely transported to the second factory 200 via the conveying pipe system 300, it is transported by replacing the hard pipe with a hose 204. The second factory 200 is generally set near the area to be treated in the desert and saline-alkali land. The hose 204 is connected to the trenching and spreading vehicle 202 through a pressure-reeling and unreeling device 201 that can be reeled and unreeled when conveying the solid-liquid mixed fluid, as its towing hose 205. The trenching and spreading vehicle 202 carries the towing hose 205 to perform trenching and spreading operations, and spreads the solid-liquid mixed fluid of coal gangue pumped in the hose 204 by the booster pump 203 on the surface of the desert or saline-alkali land.

[0058] like Figure 1 , 6 As shown in , during spreading, the trenching and spreading vehicle 202 performs reciprocating operation between the upper working line m and the lower working line n along the working direction w. At the same time, the pressure-reeling and reeling device 201 rotates the reel at the same time, so that the length of the towing hose and the stroke of the trenching and spreading vehicle 202 are synchronized. In addition, the towing hose 205 is installed on one side of the trenching and spreading vehicle 202 through a swivel joint. In order to avoid the hose 204 carried by it from getting entangled or damaging the working area during the reciprocating operation, the trenching and spreading vehicle 202 makes a 180° turn each time it reaches the upper working line m or the lower working line n, so that the running direction of the towing hose 205 in the treatment area is always consistent with the reciprocating direction of the trenching and spreading vehicle 202, thereby reducing the friction of the pipeline and minimizing the impact on the ground. The pressure-reeling and reeling device 201 can also move in the working direction w as the trenching and spreading vehicle 202 works.

[0059] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
