Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of secondary lead smelting production, and in particular relates to a special ash unloading device for a surface cooler and a surface cooler. Background Art
[0002] In the secondary lead smelting industry, waste lead-acid batteries are crushed and sorted to obtain lead paste and other components. Lead paste is generally smelted in an oxygen-enriched side-blown furnace. During the smelting process, high-temperature flue gas is generated. Generally, a cooling device of a waste heat boiler + surface cooler is used; the flue gas will cool down and the smoke dust will settle after passing through the surface cooler. At present, after the smoke ash settles, it is collected by a conical bucket and discharged by a star-shaped ash discharge valve. Because the smoke is rich in moisture, the smoke ash is wet after the surface cooler cools down. When passing through the ash discharge valve, the gap of the ash discharge valve is squeezed tightly, resulting in the inability to discharge the ash. Summary of the invention
[0003] The utility model aims to solve the shortcomings in the prior art and proposes a special dust unloading device for a surface cooler and a surface cooler.
[0004] The utility model solves the technical problem by adopting the following technical solution: a special ash unloading device for a surface cooler, comprising a connecting rod, a regulator, a bearing, and an ash baffle plate arranged at the lower ash opening of the ash unloading hopper;
[0005] The connecting rod includes an inner rod portion placed in the inner cavity of the ash unloading hopper and an outer rod portion connected to the inner rod portion and placed outside the ash unloading hopper; the inner rod portion of the connecting rod has an ash baffle corresponding to the lower ash opening of the ash unloading hopper, the outer rod portion is inserted in the bearing, the rear part of the outer rod portion of the connecting rod has a thread, and the adjuster can be detachably mounted on the outer rod portion through the thread.
[0006] The dust baffle is welded to the inner rod portion of the connecting rod, and the outer rod portion of the connecting rod is welded to the inner ring of the bearing.
[0007] The outer ring of the bearing is fixed on the support.
[0008] The regulator is heavier than the ash baffle plate, and the weight difference between the ash baffle plate and the regulator does not exceed 15%. The lower ash opening of the ash discharge hopper is sealed by the deadweight of the regulator.
[0009] The distance from the bearing to the end of the outer rod is L, and the thread length on the connecting rod is ≥ L*60%, so as to actually adjust the weight balance of the dust baffle and the regulator.
[0010] A surface cooler comprises a surface cooler body B, an ash discharge hopper connected to the surface cooler body B, and a surface cooler-specific ash discharge device as described above, which is placed at the ash discharge port of the ash discharge hopper.
[0011] The outer ring of the bearing is fixed to the outer wall of the ash discharge hopper via a support.
[0012] The regulator described in the technical solution of the utility model is connected to the connecting rod through threads and can be adjusted forward and backward.
[0013] In the technical solution of the utility model, the connecting rod can rotate around the bearing. The ash baffle rotates under the drive of the connecting rod, sinks after a certain amount of ash accumulates to complete the ash discharge, and then returns to the original position under the action of the regulator. Under normal circumstances, the deadweight of the regulator can seal the ash discharge port. When the ash reaches a certain weight and is heavier than the regulator, the ash baffle rotates around the bearing to discharge the ash and then returns.
[0014] The beneficial effects of the ash unloading device dedicated to the surface cooler of the utility model are:
[0015] 1. During normal production, dust accumulation rarely occurs;
[0016] 2. The equipment has a simple structure, which is easy to disassemble, clean, maintain and replace later;
[0017] 3. Use the equipment's own weight to balance through gravity without consuming energy. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 2 for Figure 1 A partial schematic diagram of
[0020] In the figure: 1. regulator, 2. thread, 3. bearing, 4. connecting rod, 5. ash baffle, 6. ash discharge hopper. DETAILED DESCRIPTION
[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0022] Figure 1 In the figure, one side of the cooler body B is the inlet channel A, and the other side is the outlet channel. Below the cooler body B is the ash discharge hopper 6, and the ash discharge port of the ash discharge hopper 6 is provided with a special ash discharge device for the cooler.
[0023] Figure 2In the invention, a ash unloading device for a surface cooler is disclosed, which includes a connecting rod 4, a regulator 1, a bearing 3, an ash baffle plate 5 and other devices. The connecting rod 4 is an integral structure, which is connected to the regulator 1 through a thread 2, and is welded to the inner ring of the bearing 3 in the middle; an ash baffle plate 5 is welded to the other end. The regulator 1 is heavier than the ash baffle plate 5, and the weight difference between the ash baffle plate 5 and the regulator 1 does not exceed 15%. The ash outlet of the ash unloading hopper is sealed by the deadweight of the regulator 1. The distance from the bearing 3 to the end of the outer rod is L, and the thread length on the connecting rod 4 is ≥L*60%. During actual use, it is necessary to adjust the position of the regulator 1 so that the ash baffle plate 5 can bear a certain weight of accumulated ash.
[0024] Under normal use, the connecting rod 4 can rotate around the bearing 3; the ash baffle 5 just blocks the passage of the ash hopper 6 as needed. When the ash accumulates to a certain weight, the ash baffle rotates around the bearing 3 to complete the ash unloading operation; and under the action of the regulator 1, the ash baffle 5 rotates around the bearing 3 to complete the ash unloading operation and return to the state of blocking the ash outlet of the ash unloading hopper 6. This operation is repeated over and over again to achieve the ash unloading and sealing effects.
[0025] The above-mentioned embodiment is only a preferred method of the invention of the utility model, and does not limit the utility model in any form. At the same time, this patent is not limited to surface cooling dust collectors. There are other variants and modifications without exceeding the technical solutions recorded in the claims. It should be pointed out that the specific embodiments described are only used to explain the present invention, and are not used to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
