Description

Technical Field

[0001] The utility model relates to the technical field of dilute acid filtration, in particular to a divertable dilute acid filtration structure. Background Art

[0002] Dilute acid is a liquid acid. Inorganic acids include sulfuric acid, nitric acid, and hydrochloric acid. Dilute acid refers to a solution with less solute and more solvent. In the current acid production process, the purification process of dilute acid in the purification section is an important link affecting production. With the continuous increase in environmental pressure, the requirements for the purification and treatment of dilute acid in the acid production process are becoming more and more stringent, so the burden of dilute acid filtration is also becoming heavier.

[0003] The existing patent with the authorization announcement number "CN206152436U" discloses a dilute acid filter, which includes a horizontally arranged cylinder and a filtrate collection pipe shaft fixedly installed at the central axis of the cylinder. A spray pipe is fixedly installed horizontally at the upper end of the cylinder. Filter discs are fixedly installed longitudinally at the left, middle and right ends of the filtrate collection pipe shaft and are sleeved on the filtrate collection pipe shaft. The spray pipe is externally connected to the cleaning water inlet. The filtrate collection pipe shaft is fixedly installed inside the cylinder through a flange sleeve at the left end, a middle suspension rod in the middle and an end suspension rod at the right end. The left end of the filtrate collection pipe shaft is the filtrate outlet and extends to the outside of the cylinder. The right side of the cylinder is fixedly connected to the front end cover via a suspension rod set on the outside of the cylinder. Its advantages are: the utility model has a reasonable design and is a high-efficiency, easy-to-clean precision clarification equipment;

[0004] However, there are the following deficiencies in this device:

[0005] 1. When filtering dilute acid, it is inevitable that the filter screen will be clogged. When the above device is in use, the dilute acid is filtered through one channel, which not only makes it difficult to meet the filtration load of the dilute acid, but also makes it impossible to continue filtering the dilute acid after the filter screen is clogged, resulting in increased pressure on the purification process and affecting the overall production efficiency.

[0006] 2. When the filter of the above device is clogged, it is difficult to remind the staff in time, which may result in the staff failing to deal with the equipment blockage in time, which may easily cause equipment damage and affect production results. Utility Model Content

[0021] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-3The utility model provides an embodiment of a divertable dilute acid filtering structure, comprising a filter box 1, a diverter box 13 is provided in the middle of the top of the filter box 1, a feed pipe 12 is provided in the middle of the top of the diverter box 13, fixed pipes 15 are provided on both sides of the top of the filter box 1, sleeves 6 are sleeved on the outer sides of the two fixed pipes 15, springs 16 are sleeved on the outer sides of the two groups of fixed pipes 15 near the bottom of the sleeve 6, a filter plate 17 is hinged to the bottom of the sleeve 6, and diverter pipes 10 connected to the fixed pipes 15 are provided on both sides of the top of the diverter box 13;

[0023] Two sets of gears 4 are sleeved in the middle of one end of the interior of the filter box 1, and guide rods 14 are sleeved on both sides of the bottom of the diverter box 13. The tops of the two sets of guide rods 14 are provided with sealing plugs 11 that cooperate with the diverter pipe 10. The sealing plug 11 is in the shape of a truncated cone, which can ensure the sealing effect of the diverter pipe 10. The bottoms of the two sets of guide rods 14 extend to the interior of the filter box 1 and are provided with racks A3 that mesh with the gear 4. The two sets of sleeves 6 are close to one side and are provided with racks B5 that mesh with the gear 4. Alarm components are provided on both sides of the top of the filter box 1, and discharge pipes are provided at the bottoms of both sides of the filter box 1 to discharge the dilute acid solution after diversion and filtration. A partition plate 2 is provided in the middle of the bottom of the interior of the filter box 1, and triangular guide plates are provided on both sides of the bottom of the interior of the filter box 1 to guide the dilute acid so that the dilute acid after diversion is discharged smoothly.

[0024] Furthermore, the alarm component includes an electric contact block A7, an electric contact block B8 and a warning light 9. Warning lights 9 are provided on both sides of the top of the filter box 1, and electric contact blocks A7 are provided on the tops of both sides inside the filter box 1. Electric contact blocks B8 that engage with the electric contact blocks A7 are provided on the tops of the two groups of sleeves 6 away from each other. When the filter plate 17 is blocked, the corresponding warning light 9 can be automatically started to remind the staff.

[0025] Furthermore, a threaded hole is provided on one side of the bottom of the sleeve 6, and a bolt that matches the threaded hole is provided on one side of the bottom of the filter plate 17. An inspection door is provided at one end of the filter box 1. When the filter plate 17 is blocked, the inspection door can be opened, the bolt can be rotated out of the threaded hole, and the filter plate 17 can be opened for cleaning.

[0026] Working principle: When filtering dilute acid, the dilute acid can be transported into the diverter box 13 through the feed pipe 12. When the diverter box 13 is filled with dilute acid, the dilute acid can maintain the same pressure and enter the two groups of diverter pipes 10 to divert the dilute acid, reducing the filtration load. The diverted dilute acid is transported through the diverter pipe 10 into the fixed pipe 15, and then enters the sleeve 6. The dilute acid is filtered by the filter plate 17 and can be discharged through the discharge pipe.

[0027] If one set of filter plates 17 is clogged, the dilute acid in the sleeve 6 cannot be filtered smoothly, and gravity will continue to increase. At this time, the sleeve 6 can overcome the elastic force of the spring 16 and move downward. The sleeve 6 drives the rack B5 downward, which can drive the meshing gear 4 to rotate, thereby driving the rack A3 upward, pushing the sealing plug 11 upward to block the diverter pipe 10, preventing the dilute acid from continuing to enter the clogged sleeve 6 and interfering with subsequent cleaning and maintenance work. At this time, the dilute acid in the diverter box 13 can all pass through the other set of diverter pipes 10;

[0028] And when the sleeve 6 moves downward, it can also drive the electric contact block B8 to move downward. When the sealing plug 11 blocks the shunt pipe 10, the electric contact block B8 can contact the electric contact block A7, and automatically start the warning light 9 to remind the staff so that the staff can deal with the abnormal situation in the sleeve 6 in time.
