Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electric power petrochemicals, in particular to a circular coke water filtering device. Background Art
[0002] In the electric power and petrochemical fields, dehydration bins are used to filter ash water to fully utilize the water. There are two problems in the filtration and recovery of ash water using filter nets. First, when the filter net is too dense, the ash is easily stuck on the filter net. Second, when the ash is partially attached to the filter net for a short time, although the ash is easily swept away by the subsequent water flow, during the blockage process, the water flow rate into the recovery device is slowed down due to the obstruction of the ash, reducing the overall equipment utilization efficiency. Utility Model Content
[0003] The technical problem to be solved by the present invention is to provide a circular tar water filtering device in view of the above-mentioned technical deficiencies. The outer end and the inner end of the baffle are matched to achieve the outer end to block the larger ash residue. At the same time, due to the narrowing setting from the outer end to the inner end, when the special-shaped ash residue is partially located on the inner side of the outer end, due to the narrowing of the distance, the part of the special-shaped ash residue will not be engaged with these positions, thereby ensuring the efficient operation of the filter screen. At the same time, the narrowing from the outer end to the inner end also makes it possible for a gap to remain between the baffle bars on both sides when part of the ash residue is located on the inner side of the outer end, thereby avoiding the problem of affecting the wastewater recovery efficiency when the ash residue has not been washed away.
[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: it includes a hollow cylindrical cylinder; an upper connecting ring is arranged at the upper end of the cylinder; a lower connecting ring is arranged at the lower end of the cylinder; the lower end of the cylinder is connected to the filtered water outlet through the lower connecting ring; a filter is arranged on the side wall of the cylinder; the filter includes baffles arranged circumferentially; the baffles are arranged at equal intervals along the axial direction of the cylinder; the baffles include an outer end arranged close to the radial outer side of the cylinder and an inner end close to the radial inner side of the cylinder; the outer end is arranged with a width along the axial direction of the cylinder that is greater than the inner end.
[0005] To further optimize the technical solution, the cylinder is axially fixed by a support ring arranged around the outside of the filter screen.
[0006] To further optimize the technical solution, the baffle is arranged to be uniformly narrowed and inclined along both sides from the outer end to the inner end.
[0007] To further optimize the technical solution, a gap portion is formed between two adjacent baffles; the axial spacing of the gap portion located on one side of the outer end is smaller than the width of the outer end.
[0008] To further optimize the technical solution, the axial spacing of the gap portion located on one side of the inner end is set to be greater than the sum of the widths of the two inner ends.
[0009] To further optimize the technical solution, a circular head is fixedly provided on the upper part of the cylinder through an upper connecting ring.
[0010] To further optimize the technical solution, the circular head is arranged in a semicircular closed shape.
[0011] Compared with the prior art, the utility model has the following advantages: 1. The outer end and the inner end of the baffle cooperate with each other, and this structure advantageously ensures that the outer end blocks the larger ash residue. At the same time, due to the narrowing setting from the outer end to the inner end, when the special-shaped ash residue is partially located on the inner side of the outer end, due to the narrowing of the distance, the special-shaped ash residue will not be engaged with these positions, thereby ensuring the efficient operation of the filter screen; 2. The narrowing from the outer end to the inner end, this structure advantageously ensures that when part of the ash residue is located on the inner side of the outer end, there is still a gap between the baffle bars on both sides, avoiding the problem of affecting the wastewater recovery efficiency when the ash residue has not been washed away.

[0015] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.
[0016] Specific implementation method: Combination Figure 1-2As shown, it comprises a hollow cylindrical body 1; an upper connecting ring 2 is arranged at the upper end of the body 1; a lower connecting ring 3 is arranged at the lower end of the body 1; the lower end of the body 1 is connected to the filtered water outlet 4 through the lower connecting ring 3; a filter screen 5 is arranged on the side wall of the body 1; the filter screen 5 comprises a circumferentially arranged baffle; the baffles 6 are arranged at equal intervals along the axial direction of the body 1; the baffles 6 comprise an outer end 7 arranged near the radial outer side of the body 1 and an inner end 8 near the radial inner side of the body 1; the outer end 7 has a width greater than the axial width of the body 1 The cylinder 1 is axially fixed by a support ring 9 arranged around the outside of the filter screen 5; the baffle 6 is uniformly narrowed and inclined along both sides from the outer end 7 to the inner end 8; a gap 10 is formed between two adjacent baffles 6; the axial spacing of the gap 10 located on the side of the outer end 7 is smaller than the width of the outer end 7; the axial spacing of the gap 10 located on the side of the inner end 8 is greater than the sum of the widths of the two inner ends 8; the cylinder 1 is fixedly provided with a circular head 11 at the upper part through the upper connecting ring 2; the circular head 11 is semicircular and closed.
[0017] Combination Figure 1-2 As shown, when in use, when the ash enters the gap between the two outer ends 7 along the gap portion 10 during filtering, it first passes through a smaller spacing to avoid excessive ash from entering and getting stuck between the two adjacent outer ends 7. When smaller special-shaped ash enters the gap between the two outer ends 7, the inner side of the outer end 7 gradually narrows toward the inner end 8, thereby avoiding the problem of special-shaped ash entering the inner part of the two outer ends 7 and getting stuck with the retaining bars 6 on both sides, thereby improving the purification efficiency. At the same time, when the special-shaped ash enters the gap between the two outer ends 7, although it will be washed away in the end, when the ash stops here, the gap portion 10 is gradually widened from the outside to the inside, so that even if the ash has not been washed away, it still cannot completely block the water flow, thereby avoiding the problem of affecting the recovery efficiency due to the untimely washing away of the ash.
