Description

Technical Field

[0001] This utility model relates to the field of drainage, and more specifically to a coal yard. Background Technology

[0002] In the process of coal production, storage, and transportation, coal yards are a crucial link, and their environmental conditions and operational efficiency have a vital impact on the entire coal industry. Among these issues, water accumulation in coal yards has long been a problem plaguing the industry. Water accumulation in coal yards occurs due to various reasons during daily operations. For example, during coal stacking and mining operations, water spraying is typically used to suppress dust and prevent coal ash pollution. This sprayed water, after flowing over the surface of the coal pile, can locally form coal ash water. If spontaneous combustion occurs after long-term storage in the coal yard, water is needed for firefighting, and this firefighting water, after flowing over the surface of the coal pile, can also form coal ash water. Furthermore, coal piles with high moisture content may release water. Particularly during seasons with increased rainfall, if the drainage facilities in the coal yard are inadequate, continuous rainfall can easily lead to severe water accumulation. Utility Model Content

[0003] The purpose of this invention is to overcome the problem of inefficient drainage in coal yards that exists in the existing technology.

[0004] To achieve the above objectives, this utility model provides a coal yard, comprising a stockpile, a water collection pool disposed in the stockpile, a sedimentation pool disposed at the edge of the stockpile, and an emergency drainage pipe assembly. The stockpile gradually decreases in height along its width direction, and multiple water accumulation points are formed in the stockpile. The water collection pool is adjacent to the end of the stockpile that is lower in height along its width direction. The inlet of the emergency drainage pipe assembly is disposed in the water collection pool and the water accumulation points, and the outlet of the emergency drainage pipe assembly is disposed in the sedimentation pool.

[0005] In some embodiments, the sedimentation tank is located at the end of the stockpile that is lower in the width direction and at a corner of the stockpile.

[0006] In some embodiments, the stockyard is provided with two sedimentation tanks and an internal drainage ditch connecting the two sedimentation tanks, the internal drainage ditch extending along the edge of the stockyard along its length.

[0007] In some embodiments, a plurality of water collection tanks are provided between the two sedimentation tanks, and the volume of the water collection tanks is smaller than that of the sedimentation tanks.

[0008] In some embodiments, a filter screen is provided in the water collection tank.

[0009] In some embodiments, a pressure pump is provided at the inlet of the emergency drain pipe assembly.

[0010] In some embodiments, a float is provided in the water collection tank.

[0011] In some embodiments, the float is associated with the pressure pump to turn on the pressure pump after the float reaches a predetermined liquid level.

[0012] In some embodiments, the pressure pump is a slurry pump.

[0013] In some embodiments, the system further includes an off-site drainage ditch for connecting the sedimentation tank to the wastewater treatment plant.

[0014] Through the above technical solution, the water collection tank can receive the water flowing out of the water accumulation point, and the emergency drainage pipe assembly can transport the water accumulation point to the sedimentation tank, ensuring that no water accumulation occurs in the storage yard.

Detailed Implementation

[0017] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0018] This solution provides a coal yard, which includes a stockpile 1, a water collection pool 2 located in the stockpile 1, a sedimentation pool 4 located at the edge of the stockpile 1, and an emergency drainage pipe assembly 5. The stockpile 1 gradually decreases in height in its width direction, and multiple water accumulation points 3 are formed in the stockpile 1. The water collection pool 2 is adjacent to the end of the stockpile 1 that is lower in height in its width direction. The inlet of the emergency drainage pipe assembly 5 is located in the water collection pool 2 and the water accumulation points 3, and the outlet of the emergency drainage pipe assembly 5 is located in the sedimentation pool 4.

[0019] The main structure of the storage yard 1 can be used for storing and transporting coal. It is roughly rectangular, and its height gradually decreases from one end to the other in the width direction, forming a high end and a low end, which facilitates the flow and collection of water from the high end to the low end.

[0020] Due to settlement and other reasons, multiple water accumulation points 3 inevitably form in the storage yard 1. Therefore, it is necessary to drain the water accumulated at these water accumulation points 3.

[0021] The water collection pool 2 is located at the lower edge of the storage yard 1, meaning that its location is at a lower height than the location of the water accumulation point 3. When the water accumulation at the water accumulation point 3 increases, the water can automatically flow to the nearby water collection pool 2, thus achieving automatic water collection.

[0022] In addition, an emergency drainage pipe assembly 5 is installed, which can transport water from water accumulation point 3 and water collection pool 2 to sedimentation pool 4. Especially in the case of large water accumulation, this can further ensure that water accumulation point 3 will not accumulate water.

[0023] In this solution, on the one hand, the water collection tank can receive the water flowing out from the water accumulation point, and on the other hand, the emergency drainage pipe assembly can transport the water accumulation point to the sedimentation tank to ensure that no water accumulation occurs in the storage yard.

[0024] In some embodiments, the settling tank 4 is located at the lower end of the stockpile 1 in the width direction and at a corner of the stockpile 1. The settling tank 4 is also located at the lower end of the stockpile 1, at the short edge of the stockpile 1, i.e., at a corner, reducing the impact on coal processing operations. Since the settling tank 4 is also located at the lowest point of the stockpile 1, some of the accumulated water will flow directly into the settling tank 4.

[0025] In some embodiments, the stockyard 1 is provided with two sedimentation tanks 4 and an internal drainage ditch 6 connecting the two sedimentation tanks 4. The internal drainage ditch 6 extends along the edge of the stockyard 1 along its length. The sedimentation tanks 4 are located at the lower edge of the stockyard 1, and correspondingly, the internal drainage ditch 6 is also located at the lower edge of the stockyard 1. A portion of the water accumulated in the stockyard 1 will automatically flow directly into the internal drainage ditch 6, and further flow in the internal drainage ditch 6 before entering the sedimentation tanks 4. It is understood that the depth of the internal drainage ditch 6 is less than the depth of the sedimentation tanks 4; therefore, the water in the internal drainage ditch 6 will flow into the sedimentation tanks 4.

[0026] In some embodiments, multiple water collection tanks 2 are provided between the two sedimentation tanks 4, and the volume of the water collection tanks 2 is smaller than that of the sedimentation tanks 4. (See reference) Figure 1 As shown, the water collection tank 2 occupies the space between the sedimentation tanks 4, so that the water in the storage yard 1 can flow into the corresponding water collection tank 2. The water collection tank 2 is a supplement to the sedimentation tanks 4, ensuring that water can be received in more locations.

[0027] In addition, in some embodiments, a filter grid 7 is provided in the water collection tank 2. The filter grid 7 can be arranged around the inlet of the emergency drain pipe assembly 5 to filter the accumulated water entering the emergency drain pipe assembly 5 and prevent large debris from entering the emergency drain pipe assembly 5.

[0028] In some embodiments, the inlet of the emergency drain pipe assembly 5 is provided with a pressure pump 8. The pressure pump 8 provides pumping power, allowing the accumulated water to be transported to the sedimentation tank 4. A filter screen 7 may be arranged around the pressure pump 8 to protect it from clogging by debris. The emergency drain pipe assembly 5 also includes a drain pipe for transporting accumulated water, with the pressure pump 8 connected to the inlet end of the drain pipe.

[0029] Additionally, in some embodiments, a float 9 is provided in the water collection tank 2. The float 9 can float on the accumulated water to monitor the liquid level in the water collection tank 2.

[0030] In some embodiments, the float 9 is associated with the pressure pump 8 to turn on the pressure pump 8 after the float 9 reaches a predetermined liquid level. The pressure pump 8 may be equipped with a sliding switch, and the float 9 is associated with this switch. As the float 9 moves up and down, it can open or close the sliding switch. For example, when the float 9 rises to the predetermined liquid level, it can open the sliding switch to turn on the pressure pump 8; when the float 9 falls below the predetermined liquid level, it can close the sliding switch to turn off the pressure pump 8. Through the cooperation of the float 9 and the pressure pump 8, the pressure pump 8 can automatically turn on and off according to the liquid level, improving the level of automation.

[0031] In some embodiments, the pressure pump 8 is a slurry pump.

[0032] In addition, the coal yard also includes an external drainage ditch 10 for connecting the sedimentation tank 4 to the wastewater treatment plant 11. The external drainage ditch 10 is located outside the stockpile 1, with one end connected to the sedimentation tank 4 and the other end connected to the wastewater treatment plant 11, which can transport the water in the sedimentation tank 4 to the wastewater treatment plant 11 for purification.

[0033] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, including combinations of various specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
