Description

Technical Field

[0001] The invention relates to the field of coal mine wastewater treatment, and in particular to real-time coal mine wastewater treatment equipment. Background Art

[0002] After the coal mine wastewater completes sedimentation, it continues to flow backwards for the next step of treatment. The next step is to intercept the fine suspended matter and some soluble substances in the coal mine wastewater. When the fine suspended matter and some soluble substances in the coal mine wastewater are intercepted, the flow rate of the wastewater is affected and the wastewater treatment efficiency is reduced.

[0003] As the amount of fine suspended matter and partially soluble substances retained by the filter element increases, the filter element is blocked by the retained fine suspended matter and partially soluble substances, the flow rate of wastewater decreases, and the wastewater treatment needs to be stopped and the unused filter element replaced, which again affects the wastewater treatment efficiency. Summary of the invention

[0004] In order to overcome the disadvantages that the filter element is blocked by intercepted fine suspended matter and some soluble substances, the flow rate of wastewater is reduced, the treatment of wastewater needs to be stopped and unused filter elements need to be replaced, which again affects the treatment efficiency of wastewater, the present invention provides a real-time treatment device for coal mine wastewater.

[0005] The technical implementation scheme of the present invention is: a real-time treatment equipment for coal mine wastewater, including a wastewater treatment pool I, a wastewater treatment pool II, a conveying pipeline I, a conveying pipeline II and a connecting pipeline; a wastewater treatment pool II is installed on the wastewater treatment pool I; a conveying pipeline I is connected to the wastewater treatment pool I; a conveying pipeline II is connected to the wastewater treatment pool II; the wastewater treatment pool I and the wastewater treatment pool II are commonly connected by a connecting pipeline; also including a conveying channel, a filter layer, a connecting belt and a filter plate; the wastewater treatment pool I and the connecting pipeline are commonly installed with a conveying channel, a plurality of through grooves I are opened on the conveying channel, the through grooves I are located in the connecting pipeline, and a plurality of through grooves II are opened on the conveying channel; the connecting pipeline and the conveying channel are commonly installed with a filter layer; a connecting belt is arranged in the conveying channel; a plurality of filter plates are detachably connected to the connecting belt.

[0006] Optionally, it also includes a driving motor and a rotating wheel; a groove is opened on the inner ring surface of the connecting belt; a plurality of driving motors are installed on the conveying channel; all the driving motor output shafts are installed with a rotating wheel, and the rotating wheel is provided with convex teeth, and the convex teeth on the rotating wheel mesh with the grooves on the connecting belt.

[0007] Optionally, it also includes a mounting ring and an interception net; all filter discs are fixedly connected to the interception net; all interception nets are fixedly connected to the mounting ring, the mounting ring is installed on the connecting belt, and the filter disc, the mounting ring and the interception net form a storage frame.

[0008] Optionally, the middle portion of the filter tray protrudes into the storage frame.

[0009] Optionally, a net cover is also included; all the mounting rings are detachably connected with the net cover.

[0010] Optionally, the middle portion of the net cover protrudes into the storage frame.

[0011] Optionally, a water bag is also included; all the mounting rings are equipped with a water bag, and the water inlet of the water bag is flush with the surface of the mounting ring.

[0012] Optionally, all water bags are provided with water holes, and the water holes on the water bags face the center of the mounting ring.

[0013] Optionally, a cleaning assembly is also included; a cleaning assembly is installed on the conveying channel; the cleaning assembly includes a DD motor, a connecting rod and an adsorption plate; a DD motor is fixedly connected to the wastewater treatment tank I; a connecting rod is installed on the rotating part of the DD motor; and the adsorption plate is connected to the connecting rod.

[0014] Optionally, a deformation portion is provided at the bottom of the adsorption plate.

[0015] The beneficial effect of the present invention is that the present invention filters the wastewater flowing into the conveying channel through the filter disk on the connecting belt, and the wastewater in the conveying channel is filtered by multiple filter disks, while not affecting the flow rate of the wastewater, ensuring the filtering effect of the wastewater, and then the wastewater flows from the through groove II below to the wastewater treatment tank I.

[0016] The present invention adds a driving motor and a rotating wheel to the conveying channel, and the convex teeth on the rotating wheel mesh with the grooves on the connecting belt. The driving motor is started to drive the rotating wheel to rotate, and the connecting belt is driven by the rotating wheel to rotate counterclockwise from the front to the back. The filter disc follows the movement, and the filter disc closest to the through slot I moves upward. The filter disc below replaces the filter disc closest to the through slot I to continue filtering the wastewater, thereby avoiding a reduction in the flow rate of the wastewater, and the wastewater treatment efficiency is affected again.

[0017] The present invention can replace the filter disc by manually removing the filter disc from the connecting belt and installing the unused filter disc at the position. The filter disc can also be replaced when the wastewater is filtered without affecting the filtering effect of the wastewater.

[0018] The present invention adds a mounting ring and an interception net on the filter disc, and the filter disc, the mounting ring and the interception net form a storage frame. Before filtering the wastewater, a mesh bag filled with activated carbon is tied to the storage frame. The mesh bag filled with activated carbon is referred to as the mesh bag below to prevent the mesh bag from falling out of the storage frame when the storage frame moves downward. The mesh bag increases the area for intercepting fine suspended matter and some soluble substances, thereby reducing the replacement frequency.

[0019] The present invention adds a mesh cover on the mounting ring, and shields the mesh bag through the mesh cover, so that the mesh bag in the storage frame will not fall out, and there is no need to bundle and fix it, which is convenient for subsequent replacement of the mesh bag in the storage frame. By setting the middle part of the mesh cover to bulge into the storage frame, the activated carbon in the mesh bag is squeezed and fixed through the middle part of the mesh cover bulging into the storage frame, so that the activated carbon in the mesh bag fills the space in the storage frame, thereby preventing the activated carbon in the mesh bag from moving in the storage frame and affecting the filtering effect on wastewater.

[0020] The present invention adds a water bag on the mounting ring. When wastewater is transferred downward, the wastewater enters the water bag, and the water bag begins to expand. The expanded water bag fills the gap, thereby preventing the wastewater from transferring downward between the gaps and affecting the filtration of the wastewater. By opening a water hole on the water bag, the water hole on the water bag faces the center of the mounting ring, so that the possibility of backwashing of the wastewater entering the water bag is reduced, and the gap is filled more stably.

[0021] The present invention controls the DD motor to drive the connecting rod and the adsorption plate to rotate 180 degrees counterclockwise from left to right, and then controls the DD motor to drive the connecting rod and the adsorption plate to rotate 360 ​​degrees clockwise from left to right, so that the adsorption plate rotates one circle around the storage frame, and the adsorption plate adsorbs the fine suspended matter and partially soluble matter remaining on the storage frame. By setting the bottom of the adsorption plate as a deformation part, the adsorption plate can better fit with the storage frame, better adsorb the remaining fine suspended matter and partially soluble matter, and avoid the fine suspended matter and partially soluble matter in the wastewater from being transferred to the wastewater treatment tank I, affecting the treatment effect of the wastewater.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0025] Example 1 A real-time treatment device for coal mine wastewater, such as Figure 1-Figure 7 As shown, it includes a wastewater treatment pool Ⅰ1, a wastewater treatment pool Ⅱ2, a delivery pipeline Ⅰ3, a delivery pipeline Ⅱ4 and a connecting pipeline 5; the wastewater treatment pool Ⅰ1 is installed with the wastewater treatment pool Ⅱ2; the wastewater treatment pool Ⅰ1 is connected with the delivery pipeline Ⅰ3; the wastewater treatment pool Ⅱ2 is connected with the delivery pipeline Ⅱ4; the wastewater treatment pool Ⅰ1 and the wastewater treatment pool Ⅱ2 are connected with the connecting pipeline 5; It also includes a conveying channel 6, a filter layer 7, a connecting belt 8 and a filter plate 11; the wastewater treatment tank Ⅰ1 and the connecting pipe 5 are jointly equipped with a conveying channel 6, three through grooves Ⅰ61 are opened on the conveying channel 6, the through grooves Ⅰ61 are located in the connecting pipe 5, and two through grooves Ⅱ62 are opened on the conveying channel 6; the connecting pipe 5 and the conveying channel 6 are jointly equipped with a filter layer 7; a connecting belt 8 is arranged in the conveying channel 6; and a number of filter plates 11 are detachably connected to the connecting belt 8.

[0026] It also includes a driving motor 9 and a rotating wheel 10; the inner ring surface of the connecting belt 8 is provided with a groove; two driving motors 9 are installed on the conveying channel 6; all the output shafts of the driving motors 9 are installed with a rotating wheel 10, and the rotating wheel 10 is provided with convex teeth, and the convex teeth on the rotating wheel 10 mesh with the grooves on the connecting belt 8.

[0027] It also includes a mounting ring 101 and an interception net 102; all filter discs 11 are fixedly connected to the interception nets 102; all interception nets 102 are fixedly connected to the mounting ring 101, the mounting ring 101 is installed on the connecting belt 8, and the filter disc 11, the mounting ring 101 and the interception net 102 form a storage frame.

[0028] The middle part of the filter disc 11 protrudes into the storage frame, so that the activated carbon in the middle of the mesh bag is transferred toward the interception net 102, and the activated carbon in the mesh bag is more evenly distributed.

[0029] It also includes a mesh cover 103; all the mounting rings 101 are detachably connected with the mesh cover 103.

[0030] The middle part of the mesh cover 103 protrudes into the storage frame to squeeze and fix the activated carbon in the mesh bag, thereby preventing the position of the activated carbon in the mesh bag from shifting and affecting the filtration.

[0031] It also includes a water bag 104 ; all the mounting rings 101 are mounted with the water bag 104 , and the water inlet of the water bag 104 is flush with the surface of the mounting ring 101 .

[0032] All water bags 104 are provided with water holes, and the water holes on the water bags 104 face the center of the mounting ring 101 to fill the gaps more stably.

[0033] Before using the present invention, the conveying pipe II4 is connected to the wastewater conveying device, and the pre-precipitated wastewater flows from the conveying pipe II4 to the wastewater treatment tank II2. The water level of the wastewater in the wastewater treatment tank II2 begins to rise, and the conveying pipe I3 ​​is connected to the disinfection device. After the wastewater water level in the wastewater treatment tank II2 is flush with the surface of the connecting pipe 5, the wastewater in the wastewater treatment tank II2 flows into the connecting pipe 5, and the wastewater flowing into the connecting pipe 5 falls onto the filter layer 7. The filter layer 7 filters the wastewater and intercepts fine suspended matter and some soluble substances in the wastewater. Then the filtered wastewater passes through the filter layer 7 and falls into the wastewater treatment tank I1. The wastewater falling into the wastewater treatment tank I1 flows into the conveying pipe I3, and finally the wastewater flows from the conveying pipe I3 ​​to the disinfection device.

[0034] Considering that the filter layer 7 filters the wastewater, the filter layer 7 will affect the flow rate of the wastewater, so that the water inflow per unit time of the connecting pipe 5 is greater than the water outflow per unit time, reducing the treatment efficiency of the wastewater, and the wastewater gradually accumulates in the connecting pipe 5. By adding a conveying channel 6 in the wastewater treatment tank Ⅰ1 and the connecting pipe 5, the conveying channel 6 is provided with a through groove Ⅰ61 and a through groove Ⅱ62, and the through groove Ⅰ61 is located in the connecting pipe 5. As the wastewater accumulates in the connecting pipe 5, the water level of the wastewater in the connecting pipe 5 begins to increase. When the water level of the wastewater in the connecting pipe 5 increases to be flush with the through groove Ⅰ61, the wastewater in the connecting pipe 5 flows from the through groove Ⅰ61 to the conveying channel 6, and the wastewater flowing into the conveying channel 6 is filtered by the filter disc 11 on the connecting belt 8. The wastewater in the conveying channel 6 is filtered by multiple filter discs 11, and the filtering effect of the wastewater is ensured without affecting the flow rate of the wastewater. Then the wastewater flows from the through groove Ⅱ62 below to the wastewater treatment tank Ⅰ1.

[0035] After the wastewater is filtered for a certain period of time, the fine suspended matter and partially soluble substances retained on the filter disc 11 closest to the through slot I 61 increase, and the filter disc 11 is blocked by the retained fine suspended matter and partially soluble substances, and the flow rate of the wastewater decreases. It is necessary to stop the treatment of the wastewater and replace the unused filter disc 11, which affects the treatment efficiency of the wastewater again. By adding a driving motor 9 and a rotating wheel 10 to the conveying channel 6, the convex teeth on the rotating wheel 10 are engaged with the grooves on the connecting belt 8, and the driving motor 9 is started to drive the rotating wheel 10 to rotate. The connecting belt 8 is driven by the rotating wheel 10 to rotate counterclockwise from the front to the back. The filter disc 11 follows the movement, and the filter disc 11 closest to the through slot Ⅰ 61 moves upward. The filter disc 11 below replaces the filter disc 11 closest to the through slot Ⅰ 61 to continue filtering the wastewater, so as to avoid a reduction in the flow rate of the wastewater, which will affect the wastewater treatment efficiency again. When the filter disc 11 with fine suspended matter and some soluble substances is moved to the upper through slot Ⅱ 62, the filter disc 11 is manually removed from the connecting belt 8, and the unused filter disc 11 is installed at this position. The replacement of the filter disc 11 can be completed, and it can also be replaced when the wastewater is being filtered, and it will not affect the filtering effect of the wastewater.

[0036] Considering that the filter disc 11 has a limited area for intercepting fine suspended matter and some soluble substances, the filter disc 11 is frequently replaced, and it is troublesome to frequently replace it manually. By adding a mounting ring 101 and an interception net 102 to the filter disc 11, the filter disc 11, the mounting ring 101 and the interception net 102 form a storage frame. Before filtering the wastewater, a mesh bag filled with activated carbon is tied to the storage frame. The mesh bag filled with activated carbon is referred to as a mesh bag hereinafter to prevent the mesh bag from falling out of the storage frame when the storage frame moves downward. The mesh bag increases the interception of fine suspended matter and some soluble substances. The area of ​​soluble substances is reduced, and the replacement frequency is reduced. A mesh cover 103 is added to the mounting ring 101, and the mesh bag is shielded by the mesh cover 103, so that the mesh bag in the storage frame will not fall out, and there is no need to bundle and fix it, which is convenient for the subsequent replacement of the mesh bag in the storage frame. The middle part of the mesh cover 103 is set to bulge into the storage frame, and the activated carbon in the mesh bag is squeezed and fixed by the middle part of the mesh cover 103 protruding into the storage frame, so that the activated carbon in the mesh bag fills the space in the storage frame, thereby preventing the activated carbon in the mesh bag from moving in the storage frame and affecting the filtering effect on the wastewater.

[0037] Taking into account that after using the filter disc 11 and the mounting ring 101 for a period of time, the filter disc 11 and the mounting ring 101 continue to rub against the inner wall of the conveying channel 6, and a gap gradually appears between the filter disc 11 and the mounting ring 101 and the inner wall of the conveying channel 6, some wastewater will be transferred downward from the gap, resulting in the filtration of the wastewater being affected. By adding a water bag 104 to the mounting ring 101, when the wastewater is transferred downward, the wastewater enters the water bag 104, and the water bag 104 begins to expand. The expanded water bag 104 fills the gap to prevent the wastewater from transferring downward from the gap, resulting in the filtration of the wastewater being affected. By opening a water hole in the water bag 104, the water hole on the water bag 104 faces the center of the mounting ring 101, so that the possibility of recoil of the wastewater entering the water bag 104 is reduced, and the gap is filled more stably.

[0038] Example 2 On the basis of Example 1, Figure 4-Figure 5 As shown, a cleaning assembly is also included; a cleaning assembly is installed on the conveying channel 6; the cleaning assembly includes a DD motor 110, a connecting rod 111 and an adsorption plate 112; the DD motor 110 is fixedly connected to the wastewater treatment tank Ⅰ1; the connecting rod 111 is installed on the rotating part of the DD motor 110; the adsorption plate 112 is connected to the connecting rod 111.

[0039] A deformation portion 1121 is provided at the bottom of the adsorption plate 112 to better adsorb impurities on the storage frame.

[0040] Considering that when replacing the mesh bag in the storage frame, the mesh cover 103 is manually removed from the mounting ring 101, the mesh bag in the storage frame is taken out, the unused mesh bag is placed in the storage frame, and the mesh cover 103 is installed on the mounting ring 101 again, the replacement of the mesh bag in the storage frame can be completed, but the fine suspended matter and some soluble substances remaining on the storage frame will be transferred to the wastewater treatment tank Ⅰ1, affecting the treatment effect of the wastewater, by adding a cleaning component to the conveying channel 6, the connecting rod 111 is connected to the external vacuum generator, and the connecting rod 111 and the adsorption plate 112 begin to generate adsorption force. In the process of replacing the mesh bag, after the mesh bag is taken out of the storage frame, the DD motor 110 is controlled to drive the connecting rod 111 and the adsorption plate 112 It rotates 180 degrees counterclockwise from left to right, and then controls the DD motor 110 to drive the connecting rod 111 and the adsorption plate 112 to rotate 360 ​​degrees clockwise from left to right, so that the adsorption plate 112 rotates around the storage frame. The adsorption plate 112 adsorbs the fine suspended matter and partially soluble matter remaining on the storage frame. By setting the bottom of the adsorption plate 112 as the deformation part 1121, the adsorption plate 112 can better fit with the storage frame, better adsorb the remaining fine suspended matter and partially soluble matter, and avoid the fine suspended matter and partially soluble matter in the wastewater from being transferred to the wastewater treatment tank Ⅰ1, affecting the treatment effect of the wastewater. The fine suspended matter and partially soluble matter remaining in the wastewater on the mesh cover 103 are cleaned manually.

[0041] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
