Description

Technical Field

[0001] This utility model belongs to the field of mining equipment technology, specifically relating to a mine tailings dam flood discharge device. Background Technology

[0002] Tailings dams are industrial waste storage sites constructed by damming valleys or enclosing land. They are primarily used to store tailings and other waste discharged after mineral processing in metal or non-metal mines, and also serve as a water reuse facility. As a high-potential man-made hazard, tailings dams pose a risk of collapse; therefore, they are equipped with spillways as their drainage systems. Gold mine tailings dams also have spillways for drainage. During drainage operations, the gates of gold mine tailings dams are opened, and water from the tailings dam, mixed with mineral sands and waste, enters the spillway. The impact and speed of the water entering the spillway are significant, making it difficult to effectively separate and temporarily store the mixed impurities during the drainage process, which is detrimental to long-term drainage operations. Summary of the Invention

[0003] This utility model provides a mine tailings dam flood discharge device, which has the feature of improving flood discharge efficiency.

[0004] This utility model provides the following technical solution: It includes a gate, with a fixed mesh frame fixedly connected to the rear of the gate. A separation and temporary storage assembly is provided inside the fixed mesh frame. The separation and temporary storage assembly includes a vertical mesh plate, side mesh plates, a collection mesh frame, and a baffle. There are two side mesh plates. The vertical mesh plate, the collection mesh frame, the baffle, and the two side mesh plates are fixed sequentially to form a rectangular structure inside the fixed mesh frame. A blocking and separation assembly is provided inside the separation and temporary storage assembly. The blocking and separation assembly includes a horizontal screen plate, a first inclined screen plate, and a second inclined screen plate. The first inclined screen plate and the second inclined screen plate are respectively fixed to the front and rear ends of the horizontal screen plate and are fixed between the two side mesh plates by the horizontal screen plate.

[0005] Two side mesh plates are symmetrically fixed to the top of the collection mesh frame, the collection mesh frame is snapped into the inner side of the fixed mesh frame, the side mesh plates are tightly attached to the corresponding inner side wall of the fixed mesh frame, and the side mesh plates are screwed to the fixed mesh frame.

[0006] The vertical mesh plate is located in front of the side mesh plate and the collection mesh frame. The back of the vertical mesh plate is fixedly connected to the two side mesh plates, and the back of the vertical mesh plate is close to the front end of the collection mesh frame.

[0007] The baffle is fixedly connected to the rear end of the collection mesh frame and is snapped between the two side mesh plates.

[0008] The transverse screen plate, the first inclined screen plate, and the second inclined screen plate are all snapped together between the two side mesh plates, and the transverse screen plate is screwed to the side mesh plate.

[0009] The first inclined sieve plate has its higher end pressed against the back of the vertical mesh plate, and the second inclined sieve plate has its higher end pressed against the front of the baffle.

[0010] An inclined block is fixedly connected to the front of the gate, and a guide platform is fixedly connected to the front of the vertical screen plate. The top of the guide platform is aligned with the high end of the first inclined screen plate.

[0011] The beneficial effects of this utility model are: This invention, by setting a fixed mesh frame, positions the separation and storage component and the blocking and separation component behind the gate. The vertical mesh plate, the collecting mesh frame, the baffle, and the two side mesh plates are fixed in sequence, forming an independent rectangular structure inside the fixed mesh frame. Water discharged after the gate is opened enters this rectangular structure, where the blocking and separation component in the middle of the rectangular structure performs the first round of blocking and screening. Water and some impurities pass through the blocking and separation component and enter the collecting mesh frame below for the second round of blocking and screening. This effectively performs multiple rounds of blocking and impurity separation of the discharged water, reducing the impact and flow velocity of the water. At the same time, the fixed mesh frame, side mesh plates, and collecting mesh frame discharge water outward from both sides, further reducing the drainage speed and improving the separation effect of mixed impurities in the discharged water, thereby improving the flood discharge effect and facilitating long-term flood discharge operations.

[0015] Please see Figures 1-4The present invention provides the following technical solution: it includes a gate 1, a fixed mesh frame 2 fixedly connected to the rear of the gate 1, a separation and temporary storage component 3 provided inside the fixed mesh frame 2, the separation and temporary storage component 3 including a vertical mesh plate 31, a side mesh plate 32, a collection mesh frame 33 and a baffle 34, the number of side mesh plates 32 is two, the vertical mesh plate 31, the collection mesh frame 33, the baffle 34 and the two side mesh plates 32 are fixed in sequence to form a rectangular structure inside the fixed mesh frame 2, the separation and temporary storage component 3 is provided with a blocking separation component 4 inside the separation and temporary storage component 3, the blocking separation component 4 including a horizontal screen plate 41, a first inclined screen plate 42 and a second inclined screen plate 43, the first inclined screen plate 42 and the second inclined screen plate 43 are respectively fixed to the front end and the rear end of the horizontal screen plate 41, and are fixed between the two side mesh plates 32 through the horizontal screen plate 41.

[0016] In this implementation scheme: Gate 1 is located at the spillway inlet, and Gate 1 is opened for flood discharge operations. A ramp 11 is fixedly connected to the front of Gate 1, and the ramp 11 is used to guide underwater debris through Gate 1. A fixed mesh frame 2 is fixed behind Gate 1, and the fixed mesh frame 2 is used to connect the separation and storage assembly 3 and the blocking and separation assembly 4, thereby positioning the separation and storage assembly 3 and the blocking and separation assembly 4 behind Gate 1.

[0017] The separation and temporary storage component 3 is set inside the fixed mesh frame 2. The separation and temporary storage component 3 consists of a vertical mesh plate 31, a side mesh plate 32, a collection mesh frame 33, and a baffle 34. There are two side mesh plates 32, which are symmetrically fixed on the top of the collection mesh frame 33. The vertical mesh plate 31 is located in front of the side mesh plates 32 and the collection mesh frame 33. The back of the vertical mesh plate 31 is fixedly connected to the two side mesh plates 32. The back of the vertical mesh plate 31 is close to the front end of the collection mesh frame 33. The baffle 34 is fixedly connected to the rear end of the collection mesh frame 33. The baffle 34 is engaged between the two side mesh plates 32, stably connecting the vertical mesh plate 31, the side mesh plates 32, the collection mesh frame 33, and the baffle 34. The collecting mesh frame 33 is snapped onto the inside of the fixed mesh frame 2. The side mesh plate 32 is tightly attached to the corresponding inner wall of the fixed mesh frame 2 and screwed to the fixed mesh frame 2. This securely fixes the separation and temporary storage component 3 to the inside of the fixed mesh frame 2, facilitating the installation and removal of the separation and temporary storage component 3 inside the fixed mesh frame 2. The vertical mesh plate 31, collecting mesh frame 33, baffle 34, and two side mesh plates 32 are sequentially fixed together to form an independent rectangular structure. This rectangular structure is used for the temporary storage and treatment of discharged water behind the gate 1.

[0018] The blocking and separating component 4 is located inside the separating temporary storage component 3. The blocking and separating component 4 consists of a transverse screen plate 41, a first inclined screen plate 42, and a second inclined screen plate 43. The first inclined screen plate 42 and the second inclined screen plate 43 are respectively fixed to the front end and the rear end of the transverse screen plate 41. The transverse screen plate 41, the first inclined screen plate 42, and the second inclined screen plate 43 are all snapped together between two side mesh plates 32. The transverse screen plate 41 is screwed to the side mesh plates 32 to fix the blocking and separating component 4 inside the separating temporary storage component 3. This allows for convenient fixed-point installation and disassembly of the blocking and separating component 4 inside the separating temporary storage component 3.

[0019] The fixed mesh frame 2 positions the separation and storage component 3 and the blocking and separation component 4 behind the gate 1. The vertical mesh plate 31, the collecting mesh frame 33, the baffle 34, and the two side mesh plates 32 are sequentially fixed together and as a whole inside the fixed mesh frame 2, forming an independent rectangular structure behind the gate 1. This allows the water discharged after the gate 1 is opened to pass through the vertical mesh plate 31 and enter this rectangular structure. The blocking and separation component 4, located in the middle of the rectangular structure, first contacts the discharged water, and the higher end of the first inclined screen plate 42 is pressed tightly against the vertical mesh plate 31. On the back, the higher end of the second inclined screen plate 43 is pressed against the front of the baffle 34. The horizontal screen plate 41, the first inclined screen plate 42, and the second inclined screen plate 43 work together to completely cover the open area of ​​the collection frame 33 from above. This allows the discharged water, carrying impurities, to sequentially contact the horizontal screen plate 41, the first inclined screen plate 42, and the second inclined screen plate 43. The baffle 34 blocks the water and impurities mixed in the water from behind the separation assembly 4. The horizontal screen plate 41, the first inclined screen plate 42, and the second inclined screen plate 43 perform the first round of blocking and screening of impurities in the water. At the same time, the water impacts the horizontal screen plate 41, the first inclined screen plate 42, and the second inclined screen plate 43, which can effectively reduce the water impact and slow down the water discharge speed, thereby improving the separation effect of impurities in the water. The vertical screen plate 31 has a large aperture, allowing water carrying impurities to pass through the vertical screen plate 31 and enter the inner position of the separation storage assembly 3 and the blocking separation assembly 4 for subsequent impurity separation operations. Water and some impurities pass through the blocking and separating assembly 4 and enter the collection frame 33 below. The blocking screens on the sides of the collection frame 33 and the two side screen plates 32 perform a second round of blocking and screening of impurities in the water, effectively performing multiple rounds of blocking and impurity separation in the discharged water, reducing water impact and flow velocity. Water is discharged outwards from both sides by the fixed frame 2, side screen plates 32, and collection frame 33, further reducing the drainage speed and improving the separation effect of mixed impurities in the discharged water, thereby improving the flood discharge effect and facilitating long-term flood discharge operations. A guide platform 35 is fixedly connected to the front of the vertical screen plate 31. The top of the guide platform 35 is aligned with the high end of the first inclined screen plate 42. The guide platform 35 guides underwater debris through the vertical screen plate 31 and directly into the inner area of ​​the blocking and separating assembly 4.
