Description

[Technical field]

[0001] The invention relates to the field of storage batteries, and in particular to a special high-temperature, high-humidity and high-pressure curing chamber. [Background technology]

[0002] Plate curing is a key process in the production of lead-acid batteries. It requires physical and chemical changes in the positive and negative lead pastes under high temperature and high humidity conditions, so that the lead sulfate, lead oxide, and water in the lead paste recrystallize into basic lead sulfate. The buoyancy between the grid and the lead paste and the cohesion between the lead pastes are increased, the mechanical properties of the plate are improved, and the electrochemical properties of the plate are fully utilized. In the existing technology, the gas circulation in the original plate curing room is insufficient, the temperature difference between the upper and lower parts of the room is large, the moisture difference is large, and the performance consistency of the cured plate is poor; the curing time is long, the drying time is long, and the labor intensity and time of product transfer are increased.

[0003] Patent No.: CN105322139A discloses an automatic temperature-controlled battery plate curing chamber, including a curing chamber body, a circulating fan and a steam heating box, the air outlet of the circulating fan is connected to the steam heating box and is arranged on one side of the curing chamber body, and a humidity controller, a circulating fan frequency converter and a circulating air temperature setting instrument are also arranged on the other side of the curing chamber body, and the circulating fan frequency converter is connected to the circulating fan; however, when the curing chamber is used, high pressure cannot be formed inside the curing chamber.

[0004] Patent No.: CN204348851U discloses an improved structure of a lead-acid battery curing chamber, including a curing chamber body, an inner shell is arranged in the curing chamber body, the two ends of the inner shell are in contact with the back plate and the door plate respectively, and are separated from the side plate and the top plate to form a sandwich cavity, air inlets and movable dampers matching the air inlets are arranged at the bottom of both sides of the inner shell, a dehumidification pipe is installed on the inner side of the inner shell, one end of the dehumidification pipe passes through the back plate and is installed with a dehumidification fan, and a plurality of through holes are arranged on the dehumidification pipe on the inner side of the inner shell; an air inlet is arranged at the lower part of the curing chamber body, and an air inlet cylinder is installed. However, when spraying water in the curing chamber, the uneven moisture content during the coating process leads to large moisture differences when the plates are heated after entering the kiln, which easily leads to poor consistency of the plates.

[0005] The present invention is proposed in view of the deficiencies in the prior art. [Summary of the invention]

[0006] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide a special high-temperature, high-humidity and high-pressure curing chamber.

[0007] The present invention can be implemented by the following technical solutions:

A circulating air collecting pipe is fixed on the inner wall between the steam nozzle and the corresponding tap water cooling water pipe, and a plurality of air collecting ports are evenly fixed on the circulating air collecting pipe. A plurality of inner circulating air ducts are fixedly connected between two circulating air collecting pipes, and a circulating fan is fixed on the inner circulating air duct above the curing chamber body. A plurality of pressure relief pipes connected to the interior of the curing chamber body are fixed on the curing chamber body, and a pressure control valve connected to the pressure sensor inside the curing chamber body is fixed on the pressure relief pipe. A plurality of curing vehicle tracks are also fixed inside the curing chamber body.The curing chamber body is made of reinforced concrete. The electrode plates after coating are placed on a trolley. The trolley on the curing trolley track is pushed into the interior of the curing chamber body. When the curing chamber body is full, the door on the curing chamber body is closed to form a sealed environment inside the curing chamber body. High-temperature steam is sprayed into the interior of the curing chamber body through a steam nozzle. At the same time, heated pure water is sprayed out through a pure water nozzle. High-temperature pure water is sprayed on the electrode plates through the pure water nozzle for 10-15 minutes. The circulating fan is started, and the wind is sucked in from the circulating air collecting duct on one side of the interior of the curing chamber body and then sprayed out from the circulating air collecting duct on the other side after passing through the inner circulating air duct. The wind flows clockwise when passing through the inner circulating air duct, and is set to M minutes. After M minutes, the flow direction of the wind is changed by the circulating fan. The wind speed in the inner circulating air duct is set to 10-30 meters / minute. When the internal temperature of the curing chamber body reaches the process set value, the steam nozzle stops spraying steam. When the temperature exceeds the set value, the external tap water pipe is opened, and the tap water cooling water pipe begins to flow toward The inner wall of the curing chamber body at the corresponding position is sprayed with water for cooling. When the humidity is lower than the set value, the pure water spray head continues to spray pure water while the steam spray pipe continues to spray steam into the curing chamber to ensure that the humidity inside the curing chamber body is 99%-100%. When the plate is curing, the condensed water on the top of the curing chamber body is drained by the condensed water drainage plate and flows down through the two side walls of the curing chamber body. When the pressure inside the curing chamber body reaches 0.1KG, the pressure control valve opens, the pressure relief in the curing chamber body begins, and the internal gas is discharged through the pressure discharge pipe. When the pressure inside the curing chamber is lower than 0.1Kg, the pressure control valve closes, forming a high temperature, high humidity and high pressure environment in the curing chamber body. The positive electrode curing can be completed in as short as 6 hours, and the negative electrode curing can be completed in at least 4 hours. After the plate is cured, the moisture content of the plate is 8-8.5%, and it is transferred to the oxidation drying chamber. After the plate in the curing chamber body is emptied, the tap water cooling water pipe is opened to cool the inside of the curing chamber body. When the temperature drops to 35-45℃, the plate is put in again and the curing chamber is reused.

[0009] Preferably, the tap water cooling water pipe is evenly fixed with a plurality of spray holes facing the inner wall of the curing chamber body at corresponding positions.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] By spraying the electrode plates with the device, the electrode plates are cured in a high temperature, high pressure and high humidity environment. The curing time is short, the curing chamber operates efficiently, and the cured electrode plates have good consistency. There is less stratification on the surface of the cured and dried electrode plates, which achieves the effect of energy saving and environmental protection. The water generated by the curing can be reused without worrying about water waste.
