Description

Market pot

Technical field

This utility model is related to smelting furnace manufacturing technology field, especially a kind of market pot for melting lead pig.

Background technology

Lead or metal are the raw materials of lead-acid accumulator, the Hydrocerussitum (Ceruse) in lead-acid storage battery production engineering is manufactured, grid is cast, The links such as pole group casting need lead pig is cast after market pot fusing again；There is a kind of conventional market pot, the market pot bag Body of heater is included, is had a lead pump with lead liquid outlet pipe stretched in the body of heater, is provided with into lead in the top of the body of heater side Mouthful；The closure is connected with sweep-up pipe.There are the following problems in process of production for this market pot：1st, body of heater is close to and opens wide Formula, lead liquid surface are completely exposed in atmosphere, and the lead atom in molten state has extremely strong reproducibility, in this process The lead or metal solution and air contact of molten state, can produce the lead of lead oxide, lead monoxide and middle complexity valence state Oxide and complex；Calculated with the production scale for producing the lead-acid accumulator of 5,000,000 kVAh per year, have 80-100 tons every year Lead or metal are slatterned in the form of lead skim, about 15000 yuan/ton of the price of lead, can be extrapolated by produced by lead skim Production cost is：120 150 ten thousand yuan, it is seen that the generation of lead skim is greatly had significant effect to the production cost of lead-acid accumulator； 2nd, the actually substantial amounts of air drawn by sweep-up pipe, the lead fume that most of molten lead is produced cannot be extracted by sweep-up pipe, Efficiency is low and processes incomplete, high energy consumption.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of market pot, to solve with existing market pot molten lead Production cost is high, the problem that high energy consumption and lead fume collection efficiency are low.

This utility model solve the technical scheme that adopted of technical problem for：This market pot includes body of heater and with lead liquid The lead pump of outlet pipe, the body of heater are divided into molten lead chamber and the lead pump chamber that bottom is connected by dividing plate inner space, described Lead pump chamber is built-in with the lead pump, and the lead liquid outlet pipe of the lead pump is stretched out outside the upper shed of the lead pump chamber, Yu Jin Lead fume suction pipe is provided with the upper shed of the lead pump chamber；Closure is provided with the molten lead chamber, on the closure Nitrogen inlet duct is provided with, the nitrogen inlet duct is connected with nitrogen gas generator by expansion drum；The molten lead chamber is provided with and stretches into Lead pipe is entered in its underpart, it is described enter lead pipe be provided with sweep-up pipe in stretching out the pipeline section outside the molten lead chamber.

In above-mentioned market pot technical scheme, more specifically technical scheme can also be：Aerofluxuss are provided with the closure Valve, the sealing are placed on the molten lead chamber side and are provided with sealing thermal insulation cotton.

As a result of above-mentioned technical proposal, this utility model is had the advantages that compared with prior art：1. by Molten lead chamber and the lead pump chamber that bottom is connected is divided into by dividing plate in body of heater, and lead pump is placed on into lead pump chamber, enter lead Pipe stretches into molten lead chamber lower portion, when molten lead is carried out, nitrogen gas generator by trachea to molten lead within the chamber nitrogen injection, now, Between the lead liquid liquid level of molten lead within the chamber and closure formed a chamber room filled with nitrogen, effectively can completely cut off fusion of lead with Oxygen in air is combined, and reduces the oxidation of fusion of lead, is reduced the generation of lead oxidation slag, is reduced production cost；In addition, only Lead pump chamber opening is revealed in atmosphere, makes lead fume processing region reduce more than 80%, effectively reduces the energy that environmental protection equipment processes lead fume Consumption, at the same except the effect of lead fume it is more preferable；2nd, lead fume purification vacuum exhaust equipment be provided with connect into lead pipe sweep-up pipe and be provided with position Lead fume suction pipe at nearly lead pump chamber opening, convulsion area are little, and effective rate of utilization is high, and lead fume process is more comprehensively；3rd, seal closure Sealing thermal insulation cotton is provided with molten lead chamber side, seal closure can be opened, easy cleaning molten lead chamber.

Description of the drawings

Fig. 1 is the structural representation of this utility model embodiment.

Specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail：

Market pot as shown in Figure 1 includes body of heater 9 and the lead pump 2 with lead liquid outlet pipe 2-1, and body of heater 9 is by dividing plate 9-2 handles Inner space is divided into molten lead chamber 9-3 and the lead pump chamber 9-1 that bottom is connected, and lead pump chamber 9-1 is built-in with lead pump 2, Lead liquid outlet pipe 2-1 of lead pump 2 is stretched out outside the upper shed of lead pump chamber 9-1, is provided with the upper shed of nearly lead pump chamber 9-1 Lead fume suction pipe 5, lead fume suction pipe 5 are connected with lead fume purification vacuum exhaust equipment；Furnace wall on molten lead chamber 9-3 is hinged with Closure 3 is opened by closure 3 with facilitating, and clears up lead skim；Air bleeding valve 4-1 is housed on closure 3, closure 3 is in molten lead Chamber 9-3 sides are equipped with sealing thermal insulation cotton；Nitrogen inlet duct 4 is housed on closure 3, nitrogen inlet duct 4 by expansion drum 7 with Nitrogen gas generator 8 connects；Molten lead chamber 9-3 to be provided with and enter lead pipe 6 from what sidewall slope stretched into its underpart, enters lead pipe 6 molten in stretching out Sweep-up pipe 1 is connected with pipeline section outside lead chamber 9-3, and 1 lead fume purification vacuum exhaust equipment of sweep-up pipe is connected.

During molten lead, a chamber room filled with nitrogen is formed between the lead liquid liquid level of molten lead within the chamber and closure, can be had The isolation fusion of lead of effect is combined with the oxygen in air, reduces the oxidation of fusion of lead, is reduced the generation of lead oxidation slag, is reduced life Produce cost.
