Description

Technical Field

[0001] The invention relates to the technical field of mechanical equipment, in particular to a strip steel acid-free descaling water filtering and sewage discharge device. Background Art

[0002] Compared with the traditional pickling and descaling technology, the main feature of acid-free descaling technology is that it does not use acid liquid, there is no acid pollution in the production process, and there is no acid waste liquid discharge. It is a green and environmentally friendly production process. At present, the acid-free descaling system based on abrasive water jet has been put into production, but in actual application, this technology also faces several problems. One of them is that the water circulation filtration system is always in a high-load state. The cleanliness and water volume of the water are difficult to meet the requirements of the descaling operation, so the production line has very high requirements for the sewage filtration system.

[0003] The current principle of sewage filtration is to guide sewage through the filter, which will block impurities and allow cleaner water to pass through. Obviously, larger particles of dirt and impurities will be retained at the sewage inlet and block the filter, thereby affecting the amount of filtered water. In terms of technology to prevent filter blockage, some scholars have proposed the use of a rotating filter to prevent debris from clogging the mesh; some scholars have also suggested using periodic backwash water to flush the blockage on the filter back into the sewage pool. However, these methods are only temporary solutions and only temporarily remove the dirt that blocks the mesh from the filter. As the water filtration system continues, these dirt will inevitably attach to the filter again.

[0004] Traditional sewage filtration systems are difficult to meet the water volume and water purity requirements of acid-free descaling systems based on abrasive water jets, and they need to be shut down frequently to remove dirt and impurities on the sewage inlet side, which seriously affects the production capacity and system stability. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a strip steel acid-free descaling water filtering and sewage discharge device to solve the problem that the traditional sewage filtration system is difficult to meet the requirements of the acid-free descaling system based on abrasive water jet on water volume and water purity, and it is necessary to stop the machine frequently to remove dirt and impurities on the sewage inlet side, which seriously affects the production capacity and system stability.

[0008] The first mudguard structure includes a first mudguard plate and a first support beam, and the second mudguard structure includes a second mudguard plate and a second support beam.

[0009] Wherein, the first fender and the second fender are both semicircular, the radius of the first fender is greater than the radius of the second fender, and the dirt scooping filter has a taper.

[0010] Wherein, the sewage outlet is located on the first fender and is fan-shaped, and the outer arc of the sewage outlet is the same arc as the outer arc of the first fender.

[0011] Wherein, a rotating shaft is provided at the end of the first support beam and the second support beam, and a line connecting the centers of the first fender and the second fender is parallel to the rotating shaft.

[0012] Wherein, the rotating shaft is arranged horizontally, and the plurality of sewage scooping and discharge buckets are distributed symmetrically along the rotating shaft.

[0045] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0046] like Figures 1 to 8 As shown, an embodiment of the present invention provides a strip steel acid-free descaling water filtering and sewage discharge device, including a sewage scoop and sewage discharge hopper 1, wherein the sewage scoop and sewage discharge hopper 1 includes a first mud retaining structure 101 and a second mud retaining structure 102 which are arranged in parallel, and a sewage scoop filter net 103 is provided between the first mud retaining structure 101 and the second mud retaining structure 102, and the sewage scoop filter net 103 is in the shape of a tapered curved surface; a sewage outlet 101B is provided on the first mud retaining structure 101 to discharge the dirt 7A filtered out of the sewage 7.

[0047] like Figure 3 As shown, the first mudguard structure 101 includes a first mudguard plate 101A and a first support beam 101C, and the second mudguard structure 102 includes a second mudguard plate 102A and a second support beam 102B.

[0048] The first fender 101A and the second fender 102A are both semicircular, and the radius of the first fender 101A is greater than the radius of the second fender 102A. Both ends of the dirt filter 103 are respectively connected to the arc edges of the first fender 101A and the second fender 102A, so the dirt filter 103 has a taper.

[0049] The sewage outlet 101B is located on the first fender 101A and is fan-shaped, and the outer arc of the sewage outlet 101B is the same arc as the outer arc of the first fender 101A.

[0050] like Figure 3 As shown, a rotating shaft 2 is provided at the ends of the first support beam 101C and the second support beam 102B, and a line connecting the centers of the first fender 101A and the second fender 102A is parallel to the rotating shaft 2 .

[0051] like Figure 2 As shown, the rotating shaft 2 is arranged horizontally, and the plurality of sewage scooping and discharge buckets 1 are distributed symmetrically along the rotating shaft 2 .

[0052] Among them, the number of the sewage scooping and discharge buckets 1 is 4.

[0053] like Figure 1 As shown, the rotating shaft 2 is connected to the motor 5 via the reducer 4 , and the motor 5 drives the rotating shaft 2 to rotate via the reducer 4 , so as to drive the four sewage scooping and discharge buckets 1 to rotate around the rotating shaft 2 .

[0054] A base 6 is provided below the motor 5 and the reducer 4 to raise the height of the motor 5 to prevent accidents during production from causing sewage 7 to splash into or flow into the motor 5 .

[0055] The strip steel acid-free descaling water filtering and sewage discharge device further comprises a slag bucket 3, which is arranged on a side close to the sewage outlet 101B and is used to receive dirt and impurities discharged from the sewage outlet 101B.

[0056] like Figure 8 The strip steel acid-free descaling water filtering and sewage discharge device can also be used in combination on the production line, and the sewage discharge capacity will be enhanced. Two groups of the strip steel acid-free descaling water filtering and sewage discharge device are set along the flow direction of the sewage 7. The first group of strip steel acid-free descaling water filtering and sewage discharge devices on the left and the second group of strip steel acid-free descaling water filtering and sewage discharge devices on the right perform sewage discharge operations in turn, more effectively collecting the dirt 7A separated from the sewage 7 into the slag bucket 3, and effectively improving the sewage removal and sewage discharge capacity of the system.

[0057] The working process of the strip steel acid-free descaling water filtering and sewage discharge device provided by the present invention is as follows:

[0058] like Figure 2 As shown, the four sewage scooping and discharging buckets 1 perform sewage scooping and discharging operations in a cycle in sequence as the rotating shaft 2 rotates.

[0059] S1. Figure 4 As shown, one of the sewage scooping and discharge buckets 1 is at a point P farthest from the rotating shaft 2 and begins to contact the sewage 7. As the rotating shaft 2 continues to rotate, the sewage 7 gradually enters the sewage scooping and discharge bucket 1.

[0060] S2. Figure 5 As shown, as the shaft 2 rotates, the sewage scooping and discharge bucket 1 moves away from the farthest point P of the shaft 2 and begins to leave the sewage 7. At this time, the sewage scooping and discharge bucket 1 completes its sewage scooping work;

[0061] S3. With the continued movement of the rotating shaft 2, the sewage scoop 1 gradually leaves the sewage 7, and the sewage enclosed in the sewage scoop 1 begins to be filtered, wherein most of the water flows out through the sewage scoop filter 103 under its own gravity, while the larger particle size sewage 7A and part of the water remain in the sewage scoop 1 in a muddy state;

[0062] S4. With further rotation around the rotating shaft 2, the sewage scoop 1 will be discharged, such as Figure 6 As shown, when the sewage surface MN intersects with point N of the sewage outlet 101B, the sewage discharge operation begins;

[0063] S5. Figure 7As shown, since the scooping filter 103 has a taper and forms a certain angle with the horizontal plane, the mud formed by the dirt 7A and a small amount of water mixed on the side of the scooping filter 103 near the second fender 102A will gradually slide toward the first fender 101A under the action of gravity. As the scooping and discharge hopper 1 rotates, the mud accumulated at the first fender 101A will slide into the slag bucket 3 through the discharge port 101B, completing the discharge operation.

[0064] like Figure 8 As shown, the sewage 7 with most of the dirt 7A treated by the strip steel acid-free descaling water filtering and sewage discharge device flows into the subsequent sewage filter 8 for filtration, and the filtered water enters the acid-free descaling system for recycling.

[0065] In the above scheme, the sewage hopper is used to circulate to separate dirt and impurities from the sewage, thereby reducing the blockage at the filter inlet and achieving efficient operation of the water filtration system, effectively reducing the number of shutdowns for sewage discharge, and greatly improving the stability of the acid-free descaling system.

[0066] The above is a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. It should be noted that the strip steel acid-free descaling water filtering and drainage device is mainly used in acid-free descaling systems, and its application in other fields such as car washing, urban sewage treatment, etc. is also protected.
