Description

Technical Field

[0001] The invention relates to the technical field of cement preparation equipment, and in particular to cement production wastewater treatment equipment and a treatment process. Background Art

[0002] Cement is a powdery, hydraulic, inorganic cementitious material. After adding water and stirring, it becomes a slurry, which can harden in the air or in water, and can firmly bond sand, stone and other materials together. During the production process of cement, when the clinker is cooled, it needs to be cooled with water, and the cooling water becomes sewage after it is used up. During the cement calcination process, sewage is also generated when cleaning the exhaust gas, and sewage is also generated when cement is used to clean the equipment.

[0003] Therefore, sewage will be generated in all processes of cement production. In the process of cement production, the wastewater generated usually needs to be purified before it can be discharged. When treating the sewage generated during cement production, it is generally necessary to collect the sewage in a centralized manner, and then remove the sundries and organic matter in the sewage through neutralization reaction, sedimentation treatment, biological treatment, etc.;

[0004] In the prior art, when conducting neutralization reaction or precipitation treatment, sewage is generally first concentrated in a reaction tank, and then various adjusting solvents or flocculants are injected to make the debris clump and precipitate, and then salvage and filter.

[0016] A cement production wastewater treatment equipment and treatment process, using the cement production wastewater treatment equipment as described above, is characterized in that it includes the following steps:

[0017] S1: First, the cement production wastewater is discharged into the water collection tank, and then the multi-stage cylinder is controlled to drive the filter plate to sink into the water collection tank. During the sinking process, the filter plate scrapes the inner wall of the water collection tank. After contacting the guide block, the filter plate moves along the bottom of the water collection tank and scrapes the bottom of the water collection tank, and then the sediment at the bottom of the water collection tank can be scraped off;

[0019] S3: After the moisture in the sediment is removed, the filter plate is controlled to enter the dust collecting chamber, the first extrusion plate and the second extrusion plate are turned over, the surface of the filter plate is scraped, the adsorption force of the sediment on the top of the filter plate on the filter plate is reduced, and the sediment falls into the dust collecting chamber, and then the motor is controlled to drive the fan roller to rotate, generating wind force to clean the filter holes of the filter plate for subsequent use.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The cement production wastewater treatment equipment controls the filter plate, the first extrusion plate and the second extrusion plate to return when it is necessary to filter the sediment and flocculants. The first extrusion plate and the second extrusion plate perform preferential filtration during the return process. After the filtration is completed, the first extrusion plate and the second extrusion plate are controlled to flip relative to each other and contact each other, so that the first extrusion plate and the second extrusion plate remove the moisture in the flocculants, and then press down to contact the top of the filter plate, and then remove the moisture in the sediment on the top of the filter plate, thereby avoiding the waste of water resources and improving the filtering effect on the bottom of the water collection tank.

[0022] 2. The cement production wastewater treatment equipment scrapes off the sediment adhered to the surface of the filter plate through the contact of the first extrusion plate and the second extrusion plate with the filter plate, and then throws off the flocculants through its own rotation. During the cleaning process, the fan roller is driven by the motor to rotate to generate wind force, thereby improving the cleaning effect of the filter plate, the first extrusion plate and the second extrusion plate.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Embodiment 1:

[0037] See also Figure 1-11 A cement production wastewater treatment device includes a sewage pool 1 and a controller, characterized in that: a water collecting pool 11 is provided on one side of the inner cavity of the sewage pool 1, a dust collecting chamber 12 is provided on the side of the inner cavity of the sewage pool 1 away from the water collecting pool 11, a ceiling 13 is fixed on the top of the sewage pool 1, and a solvent box 14 is fixed on the side of the top of the ceiling 13 close to the water collecting pool 11;

[0038] Guide blocks 2 are fixed to the bottom of both sides of the water collection tank 11, and a driving motor 3 is fixed to the outside of the ceiling 13. The driving motor 3 is controlled by a controller, and a lead screw 31 is fixed to the outside of the output shaft of the driving motor 3, and one end of the lead screw 31 is rotatably connected to the ceiling 13. A salvage component is provided on the outside of the lead screw 31, and the salvage component is used to salvage sediment in the sewage;

[0039] The salvaging assembly includes a moving block 4, which is provided with two groups of moving blocks 4, each group of two. The moving block 4 is slidably connected to the lead screw 31, and a multi-stage cylinder 41 is fixed to the bottom of the moving block 4. The multi-stage cylinder 41 is controlled by a controller. A support plate 42 is fixed to the bottom of the output end of the multi-stage cylinder 41. Two support plates 42 are provided, which are respectively located below the two groups of multi-stage cylinders 41. The bottom of the support plate 42 is rotatably connected to a rubber belt 43, and the inner side of the rubber belt 43 is rotatably connected to a filter plate 44;

[0040] A first electromagnet 45 is fixed inside the filter plate 44 on the side away from the dust collecting chamber 12, an inner slide groove 46 is provided inside the filter plate 44 on the side close to the dust collecting chamber 12, a first spring 47 is fixed inside the inner slide groove 46, a connecting block 48 is fixed outside the end of the first spring 47 away from the dust collecting chamber 12, and the connecting block 48 is slidably connected to the inner slide groove 46, a second electromagnet 49 is fixed outside the end of the connecting block 48 close to the first electromagnet 45, and the first electromagnet 45 and the second electromagnet 49 have opposite magnetic properties;

[0041] During the specific operation, the sewage generated during cement production is first discharged into the water collection tank 11, and then the solvent and flocculant that need to be adjusted are injected into the sewage through the solvent box 14 to perform a neutralization reaction and flocculation. When the cement sewage is undergoing a neutralization reaction, the driving motor 3 is controlled by the controller to start, and the driving motor 3 drives the lead screw 31 to rotate, and the lead screw 31 drives the moving block 4 to move, so that the moving block 4 drives the multi-stage cylinder 41 to move to the top of the water collection tank 11, and then the multi-stage cylinder 41 is controlled by the controller to start, so that the multi-stage cylinder 41 drives the two support plates 42 to descend, so that the support plate 42 drives the rubber belt 43 and the filter plate 44 to descend, so that the filter plate 44 descends along the inner wall of the water collection tank 11;

[0042] During the descent process, the filter plate 44 performs a preliminary scraping operation on the inner wall of the water collection pool 11 to remove the sediment on the inner walls on both sides of the water collection pool 11, until one end of the filter plate 44 contacts the guide block 2, and is guided by the guide block 2 to make the filter plate 44 flip along the horizontal direction of the bottom of the water collection pool 11. As the multi-stage cylinder 41 controls the support plate 42 to continue to descend, the filter plate 44 scrapes the bottom of the water collection pool 11 and shovels the sediment at the bottom of the water collection pool 11 to the top of the filter plate 44;

[0043] As the multi-stage cylinder 41 continues to press downward, the two support plates 42 move in opposite directions until the two support plates 42 contact each other, and then the first electromagnet 45 and the second electromagnet 49 are energized through the controller, so that the first electromagnet 45 and the second electromagnet 49 are attracted to each other. Since the connecting block 48 is slidably connected with the inner slide groove 46, the bottom of the water collection tank 11 is covered with the first electromagnet 45, the connecting block 48, the second electromagnet 49 and the two filter plates 44. When the bottom of the water collection tank 11 is covered, the sediment produced by the sewage neutralization reaction and sedimentation treatment in the water collection tank 11 gradually falls to the top of the two filter plates 44, which then plays a role in collecting the sediment;

[0044] Furthermore, when the first electromagnet 45 and the second electromagnet 49 are attracted to each other after being energized, the first electromagnet 45 and the second electromagnet 49 emit heat during the process of energizing the first electromagnet 45 and the second electromagnet 49, and the heat diffuses in the cement sewage along with the flow of the cement sewage, thereby accelerating the neutralization reaction speed of the regulator and the flocculant, thereby improving the efficiency of cement sewage treatment;

[0045] After the neutralization reaction and precipitation treatment are completed, the multi-stage cylinder 41 can be controlled to return through the controller, and the multi-stage cylinder 41 drives the support plate 42, the rubber belt 43 and the filter plate 44 to return. Since the first electromagnet 45 and the second electromagnet 49 are in an adsorption state, the filter plate 44 can perform a salvage and filter operation on the surface of the cement sewage during the return process, and can filter and remove the floating objects on the surface of the cement sewage.

[0046] It should be particularly noted that the lengths of the inner walls of the water collecting pool 11 and the dust collecting chamber 12 are the same, and a drainage channel is provided at the bottom of the water collecting pool 11. There are four moving blocks 4, two of which are in a group, and the spacing between the two groups of moving blocks 4 corresponds to the lengths of the water collecting pool 11 and the dust collecting chamber 12. There are four multi-stage cylinders 41, two of which are in a group, and a support plate 42 is fixed to the bottom of each group of multi-stage cylinders 41, and the two support plates 42 are arranged opposite to each other, and the outer sides of the two support plates 42 are both in contact with the inner wall of the water collecting pool 11 or the dust collecting chamber 12, and the first electromagnet 45 and the second electromagnet 49 are both controlled by the controller to turn on and off the power.

[0047] Embodiment 2:

[0048] An electric telescopic rod 5 is fixed inside the support plate 42, a connecting plate 51 is fixed on the top of the output end of the electric telescopic rod 5, a connecting rod 52 is fixed on the bottom of one side of the connecting plate 51, the connecting rod 52 is located on the inner side of the support plate 42, an outer frame 53 is fixed on the bottom of the connecting rod 52, and mounting blocks 54 are fixed at the middle positions of both sides of the outer frame 53;

[0049] A first motor 6 is fixed inside one mounting block 54, and a first extrusion plate 61 is fixed outside the output shaft of the first motor 6; a second motor 62 is fixed inside another mounting block 54, and a second extrusion plate 63 is fixed outside the output shaft of the second motor 62; the first extrusion plate 61 and the second extrusion plate 63 are arranged opposite to each other; an end of the first extrusion plate 61 away from the first motor 6 is rotatably connected to the outer frame 53; an end of the second extrusion plate 63 away from the second motor 62 is rotatably connected to the outer frame 53; filter holes are formed on the surfaces of the filter plate 44, the first extrusion plate 61 and the second extrusion plate 63; and the filter holes between the filter plate (44) and the first extrusion plate (61) and the second extrusion plate (63) are arranged in a staggered manner;

[0050] During the specific operation, on the basis of the first embodiment, when the filter plate 44 enters the cement sewage in the sump 11 under the action of the multi-stage cylinder 41, the support plate 42 drives the electric telescopic rod 5 to also enter the cement sewage, and the electric telescopic rod 5 drives the connecting plate 51 and the connecting rod 52 to enter the cement sewage synchronously, so that the connecting rod 52 drives the outer frame 53 and the mounting block 54 to enter the cement sewage, so that the mounting block 54 drives the first motor 6, the first extrusion plate 61, the second motor 62 and the second extrusion plate 63 to enter the cement sewage synchronously;

[0051] When the first motor 6, the first extrusion plate 61, the second motor 62 and the second extrusion plate 63 enter the cement sewage, the first motor 6 and the second motor 62 are started by the controller, the first motor 6 drives the first extrusion plate 61 to flip in the cement sewage, and the second motor 62 drives the second extrusion plate 63 to flip in the cement sewage, and the cement sewage is agitated as the second extrusion plate 63 and the first extrusion plate 61 flip. When the solvent box 14 injects the regulator and the flocculant into the cement sewage, the neutralization reaction of the solvent and the cement sewage can be accelerated by flipping the first extrusion plate 61 and the second extrusion plate 63, and the heat emitted by the first electromagnet 45 and the second electromagnet 49 after being energized can be diffused, so that the heat is transferred more evenly in the cement sewage, and the speed and efficiency of the neutralization reaction of the regulator and the flocculant are further enhanced.

[0052] When the multi-stage cylinder 41 controls the support plate 42 to return, the support plate 42 drives the rubber belt 43 and the filter plate 44 to return synchronously, and the support plate 42 drives the electric telescopic rod 5 to return synchronously during the return process, and the electric telescopic rod 5 drives the connecting plate 51 and the connecting rod 52 to return synchronously, and the connecting rod 52 drives the outer frame 53 to return, and the outer frame 53 drives the mounting block 54 to return, and the mounting block 54 drives the first motor 6 and the second motor 62 to return, and the first motor 6 drives the first extrusion plate 61 to return, and the second motor 62 drives the second extrusion plate 63 to return;

[0053] When the first extrusion plate 61 and the second extrusion plate 63 follow the filter plate 44 on the return journey, they preliminarily salvage and filter the flocculants in the cement sewage and on the surface, and then the remaining flocculants salvaged by the first extrusion plate 61 and the second extrusion plate 63 continue to be filtered by the filter plate 44 until the filter plate 44 is completely separated from the surface of the cement sewage in the water collection tank 11. When the filter plate 44, the first extrusion plate 61 and the second extrusion plate 63 are separated from the surface of the cement sewage, the moisture of the top sediment and flocculants can be sieved into the interior of the water collection tank 11;

[0054] Further, when the filter plate 44 is completely separated from the surface of the cement sewage, the first motor 6 and the second motor 62 can be controlled by the controller, so that the first motor 6 drives the first extrusion plate 61 to rotate toward the ceiling 13, and the second motor 62 drives the second extrusion plate 63 to rotate toward the ceiling 13, so that the first extrusion plate 61 and the second extrusion plate 63 approach each other during the rotation process until the first extrusion plate 61 and the second extrusion plate 63 contact each other;

[0055] When the first extrusion plate 61 and the second extrusion plate 63 are turned over, the floccules on the top thereof are driven to turn over synchronously, and as the first extrusion plate 61 and the second extrusion plate 63 abut against each other, the floccules on the first extrusion plate 61 and the second extrusion plate 63 come into contact, and as the first extrusion plate 61 and the second extrusion plate 63 abut against each other and close, the floccules are squeezed, so that the water of the floccules between the first extrusion plate 61 and the second extrusion plate 63 is squeezed out, and after the water falls on the top of the filter plate 44, it is recovered into the inside of the water collection tank 11 through the filter holes of the filter plate 44, thereby preventing the cement wastewater from being discharged along with the floccules, reducing the water that can be treated, and then increasing the amount of water that can be reused later;

[0056] When the moisture of the flocculent between the first extrusion plate 61 and the second extrusion plate 63 is squeezed out, the controller controls the first motor 6 and the second motor 62 to drive the first extrusion plate 61 and the second extrusion plate 63 to reset. When the first extrusion plate 61 and the second extrusion plate 63 are reset, the controller starts the electric telescopic rod 5, and the electric telescopic rod 5 controls the return of the connecting plate 51. During the return process, the connecting plate 51 drives the connecting rod 52 to move toward the filter plate 44, and the connecting rod 52 drives the outer frame 53 and the mounting block 54 to move toward the filter plate 44. Then the mounting block 54 drives the first motor 6, the first extrusion plate 61, the second motor 62 and the second extrusion plate 63 to move toward the filter plate 44.

[0057] In the process of the outer frame 53, the first extrusion plate 61 and the second extrusion plate 63 moving toward the filter plate 44, the outer frame 53, the first extrusion plate 61 and the second extrusion plate 63 are respectively in contact with the two filter plates 44, and as the electric telescopic rod 5 continues to return, the pressure of the outer frame 53, the first extrusion plate 61 and the second extrusion plate 63 after contacting the filter plate 44 gradually increases, and then the sediment on the top of the filter plate 44 is squeezed by the outer frame 53, the first extrusion plate 61 and the second extrusion plate 63, so that the water in the sediment on the top of the filter plate 44 is squeezed out and drips into the water collection tank 11 through the filter plate 44. In this process, the water in the sediment is also recovered, which prevents the sediment from taking away the water when it is removed, thereby increasing the amount of reusable water;

[0058] It should be noted that the initial state of the electric telescopic rod 5 is the ejection state, that is, the initial state position of the electric telescopic rod 5 driving the connecting plate 51 and the connecting rod 52 is located above the filter plate 44, that is, the connecting rod 52 and the first extrusion plate 61 and the second extrusion plate 63 are located above the filter plate 44, and the filter holes staggered between the filter plate 44 and the first extrusion plate 61 and the second extrusion plate 63 can prevent moisture from flowing back to the top of the first extrusion plate 61 and the second extrusion plate 63, wherein the electric telescopic rod 5, the first motor 6, and the second motor 62 are all controlled by the controller.

[0059] Embodiment three:

[0060] A ventilation chamber 7 is provided inside the inner wall of the sewage pool 1 near the dust collecting chamber 12, and the bottoms of both sides of the ventilation chamber 7 are rotatably connected with fan blade rollers 71, and the external transmission of the fan blade roller 71 near one end of the first motor 6 is connected with a belt 72, and a motor 73 is fixed to the outside of the fan blade roller 71 near the water collecting pool 11, and the motor 73 is fixed to the outside of the sewage pool 1;

[0061] An air outlet is provided on the surface of the inner wall of the dust collecting chamber 12, a second spring 8 is fixed inside the ventilation chamber 7 near the water collecting pool 11, a first push rod 81 is fixed at one end of the second spring 8, and the first push rod 81 passes through the air outlet of the ventilation chamber 7, a third spring 82 is fixed inside the ventilation chamber 7 away from the water collecting pool 11, a second push rod 83 is fixed outside one end of the third spring 82, and the second push rod 83 passes through the air outlet of the ventilation chamber 7;

[0062] During the specific operation, after the water content of the flocculants and sediments on the top of the filter plate 44, the first squeezing plate 61 and the second squeezing plate 63 is suppressed and removed, the controller can be used to control the driving motor 3 to rotate in the reverse direction, so that the lead screw 31 rotates in the reverse direction, so that the lead screw 31 drives the salvaging assembly to move toward the dust collecting chamber 12 until the salvaging assembly moves to the top of the dust collecting chamber 12;

[0063] Then, the multi-stage cylinder 41 is controlled to start again, so that after the multi-stage cylinder 41 is pushed out, the support plate 42 is driven to descend, and the support plate 42 drives the rubber belt 43 and the filter plate 44 to descend, and the filter plate 44 is made to descend above the air outlet on the surface of the ventilation chamber 7, and then the first motor 6 and the second motor 62 are controlled, so that the first motor 6 drives the first extrusion plate 61 to flip toward the dust collecting chamber 12, and the second motor 62 drives the second extrusion plate 63 to flip toward the dust collecting chamber 12;

[0064] During the flipping process, the first extrusion plate 61 and the second extrusion plate 63 contact the two filter plates 44 respectively. During the flipping process, the first extrusion plate 61 abuts against the filter plate 44 below it and performs a scraping operation on the filter plate 44 below it to scrape off the sediment adhered to the top of the filter plate 44. Similarly, during the flipping process, the second extrusion plate 63 abuts against the filter plate 44 below it and performs a scraping operation on the filter plate 44 below it. With the continuous flipping of the first extrusion plate 61 and the second extrusion plate 63, the pressure of the first extrusion plate 61 and the second extrusion plate 63 on the two filter plates 44 gradually increases until the first electromagnet 45 and the second electromagnet 49 are released from the adsorption state. Under the action of the first extrusion plate 61 and the second extrusion plate 63, the two filter plates 44 quickly move toward the inner walls on both sides of the dust collecting chamber 12 and touch each other. When the filter plates 44 contact the inner walls of the dust collecting chamber 12, they vibrate, so that the sediment remaining adhered to the surfaces of the two filter plates 44 is shaken off into the interior of the dust collecting chamber 12.

[0065] Furthermore, when the filter plate 44 touches the inner wall of the dust collecting chamber 12, the two filter plates 44 contact the first push rod 81 and the second push rod 83 respectively, so that the second push rod 83 presses the third spring 82, and the first push rod 81 presses the second spring 8, and under the action of the second spring 8 and the third spring 82 returning, the first push rod 81 and the second push rod 83 shake in the air outlet of the ventilation chamber 7, and in the process of repeated shaking of the second push rod 83 and the first push rod 81, the two filter plates 44 are repeatedly vibrated, which further strengthens the separation of the sediment adhered to the surface of the filter plate 44, thereby preventing the filter plate 44 from bringing the remaining sediment residue into the treated water in the sump 11 again during the subsequent cement sewage treatment process, thereby improving the treatment quality of the cement sewage;

[0066] During the process of the sediment on the surface of the filter plate 44 vibrating and separating, the first extrusion plate 61 and the second extrusion plate 63 are continuously controlled to flip, so that the first extrusion plate 61 and the second extrusion plate 63 can throw away the flocculants adhering to the surface thereof, thereby preventing the flocculants from adhering to the surfaces of the first extrusion plate 61 and the second extrusion plate 63, and preventing the first extrusion plate 61 and the second extrusion plate 63 from bringing the residual flocculants into the treated water of the water collection tank 11 again, thereby improving the quality of cement wastewater treatment;

[0067] Furthermore, in the process of the filter plate 44 vibrating to separate the sediment and the first extrusion plate 61 and the second extrusion plate 63 throwing off the flocculants, the motor 73 is started by the controller, and under the action of the belt 72, the two blade rollers 71 are driven to rotate simultaneously, so that the wind force generated by the blade roller 71 is blown to the filter plate 44, the first extrusion plate 61 and the second extrusion plate 63 through the air outlet of the ventilation chamber 7. During the blowing process, the wind force of the blade roller 71 can perform air-blast cleaning operation on the filter holes on the surfaces of the filter plate 44, the first extrusion plate 61 and the second extrusion plate 63, thereby further improving the cleaning efficiency of the filter plate 44, the first extrusion plate 61 and the second extrusion plate 63 and the quality of subsequent treatment of cement wastewater;

[0068] As the first push rod 81 and the second push rod 83 continue to shake in the air outlet of the ventilation chamber 7, it can prevent sediment or flocculants from blocking the air outlet of the ventilation chamber 7, thereby ensuring the air outlet rate of the ventilation chamber 7, and further improving the efficiency of cleaning the filter plate 44, the first extrusion plate 61 and the second extrusion plate 63.

[0069] It should be noted that a sliding door is provided on the inner wall of the dust collecting chamber 12 for cleaning the debris inside the dust collecting chamber 12, and the motor 7 is controlled by a controller.

[0071] S1: First, the cement production wastewater is discharged into the water collection tank 11, and then the multi-stage cylinder 41 is controlled to drive the filter plate 44 to sink into the water collection tank 11. During the sinking process, the filter plate 44 scrapes the inner wall of the water collection tank 11. After contacting the guide block 2, the filter plate 44 moves along the bottom of the water collection tank 11 and scrapes the bottom of the water collection tank 11, and then the sediment at the bottom of the water collection tank 11 can be scraped off;

[0072] S2: When the two filter plates 44 are completely in contact with the bottom of the water collection tank 11, the first electromagnet 45 and the second electromagnet 49 are energized, so that the first electromagnet 45 adsorbs the second electromagnet 49, and then the two filter plates 44 are fixed, and then the multi-stage cylinder 41 is controlled to drive the filter plates 44 to return. When the filter plates 44 are separated from the sewage, the first extrusion plate 61 and the second extrusion plate 63 are driven to pre-salvage the sewage, and the outer frame 53 is controlled to descend, so that the first extrusion plate 61 and the second extrusion plate 63 squeeze and remove water from the sediment on the top of the filter plate 44, thereby reducing the moisture in the sediment;

[0073] S3: After the moisture in the sediment is removed, the filter plate 44 is controlled to enter the dust collecting chamber 12, the first extrusion plate 61 and the second extrusion plate 63 are turned over, the surface of the filter plate 44 is scraped, the adsorption force of the sediment on the top of the filter plate 44 on the filter plate 44 is reduced, and the sediment falls into the dust collecting chamber 12, and then the motor 73 is controlled to drive the fan roller 71 to rotate, generating wind force to clean the filter holes of the filter plate 44 with air for subsequent use.
