Description

Technical Field

[0001] The utility model belongs to the technical field of lead-acid battery raw material production equipment and relates to a dust removal device for lead powder. Background Art

[0002] Lead powder is an important raw material for lead-acid batteries. In the production process of lead powder, the lead powder airflow is filtered and dusted. The dust collector in the existing technology is for filtering mass industrial production. A small amount of lead powder is discharged into the atmosphere with the mixed air flow. If the trace dust such as wood chips and iron meets the national emission standards, the impact on the human body and the environment can be ignored. However, due to the unique toxic chemical properties of lead powder, even a trace amount of lead powder dust will have an adverse effect on the physical and mental health of workers. The long-term accumulation of trace lead powder emissions will pollute the surrounding environment. For this reason, we have launched a dust removal device for lead powder. Utility Model Content

[0011] like Figure 1-2 As shown, the following are specific embodiments of the utility model and combined with the accompanying drawings, the technical scheme of the utility model is further described, but the utility model is not limited to these embodiments. A dust removal device for lead powder, the dust removal device includes a tank body 1, the outer wall of the tank body 1 is provided with an air inlet pipe 2 along the tangential direction, the top of the tank body 1 is provided with a water supply pipe 3, the waist of the tank body 1 is provided with a sieve plate 400 for cutting large bubbles, the bottom of the tank body 1 is provided with a collecting chamber 101 for collecting lead powder, the collecting chamber 101 is provided with a valve, a conical cavity 102 is provided between the collecting chamber 101 and the tank body 1, the inner wall of the conical cavity 102 is provided with a plurality of baffles 5, the outer wall of the conical cavity 102 is provided with a drain pipe 6, and the top of the tank body 1 is provided with an air outlet 7.

[0012] Preferably, a fixed frame 8 is provided on the outer side of the tank body 1 .

[0013] Preferably, the sieve plate 400 is evenly and densely distributed with a plurality of sieve holes 401 for cutting large bubbles and weakening the kinetic energy of the lead powder when the bubbles escape.

[0014] In this embodiment, when the utility model is applied, the valve of the water adding pipe 3 is first opened to add water to the inner cavity of the tank body 1, and the water addition is stopped after the water surface overflows the sieve plate 400.

[0015] The lead powder mixed air flow discharged from the lead powder sorting device is discharged into the inner cavity of the tank body 1 from the air inlet pipe 2. The lead powder mixed air flow rotates along the inner wall of the tank body 1. The water in the tank body 1 forms a vortex. The mixed air flow is affected by the resistance of the water, which reduces its kinetic energy. At the same time, it diffuses along the inner wall of the tank body 1 into the water in the central area, and then overflows to the water surface. The generated bubbles are cut into multiple small bubbles by the sieve holes 401 of the sieve plate 400, and then overflow to the water surface and are discharged into the atmosphere from the air outlet 7.

[0016] When the lead powder rotates on the inner wall of the tank body 1 with the mixed air flow, the water in the tank body 1 forms a vortex. Since the density of the lead powder is greater than that of the air, the resistance of the lead powder in the water is also greater than that of the air. Due to the effect of inertia, the lead powder breaks away from the entrainment of the air flow and sinks downward. The lead powder slides from the conical cavity 102 to the collection chamber 101. After an operation cycle, the lead powder sorting device is shut down, the air intake pipe 2 stops intake, and the valve of the drain pipe 6 is opened to drain the water. After the water is drained, the valve of the collection chamber 101 is released, and the lead powder in the collection chamber 101 slides from the collection chamber 101 to the collection container.

[0017] Compared with the traditional technology, the air intake pipe of the traditional technology is directly inserted into the water, and the lead powder mixed air flow violently hits the inner wall of the tank body to generate large bubbles. When the large bubbles burst, the escaping air flow will entrain part of the lead powder from the water surface. The utility model inserts the air intake pipe tangentially along the inner wall of the tank body, and the mixed air flow entrains the lead powder to rotate along the inner wall of the tank body. Compared with the violent impact of direct insertion, the resistance of the mixed air flow is relatively reduced, and the energy of the air flow escaping from the water surface entraining the lead powder is also relatively reduced. A mesh screen is added to divide the large bubbles, further weakening the energy of the air flow escaping from the water surface entraining the lead powder. Secondly, the multiple baffles added to the conical cavity have a certain slowing effect on the rotating vortex, which is beneficial to the sinking and collection of the lead powder.

[0018] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
