Description

High-efficient material feeding unit

Technical Field

The invention belongs to the technical field of vibration conveying and conveying equipment, and particularly relates to a high-efficiency feeding device.

Background

The waste lead storage batteries contain a large amount of recyclable resources such as lead and copper, and thus are recycled after the lead storage batteries are damaged or the consumption of the stored electric energy is completed. The recovery of lead in the lead storage battery mainly comprises the working procedures of crushing, impurity removal, smelting, furnace placing, precipitation impurity removal and forming, and during smelting, lead particles and lead plaster obtained after impurity removal are required to be placed into the smelting furnace. The traditional lead shot feeding mode is manual operation, but the highest temperature in the smelting furnace can reach 1300 degrees, and manual operation is very easy to cause burn, so that the material is usually fed by using a feeding device, the existing feeding device comprises a base, an installation frame and a feeding bin arranged on the installation frame, springs are arranged between the top of the feeding bin and the installation frame, and springs are also arranged between the installation frame and the base; the two side walls of the feeding bin are provided with vibrators which are transversely arranged, and the front end of the feeding bin is provided with a feeding chute. During the use, start the vibrator for the vibrator vibration gives the power of the material vibration in the pay-off storehouse, and through setting up the spring, at the in-process of vibrator vibration, makes pay-off storehouse also take place vibration and displacement, and gives the material a power of throwing forward and sending, thereby accomplishes the pay-off. Set up the spring simultaneously, can play a buffering, avoid the feeding bin direct to take place to strike the feeding bin that causes impaired with the mounting bracket.

However, the inventor finds that the feeding needs 3-4 hours to complete the feeding of a smelting furnace by using the existing feeding device in the actual operation process, and the feeding efficiency is low; through the investigation of the feeding devices on the market, the feeding efficiency of the feeding devices in the whole industry is found to be almost the same, but the time of the whole recovery process is long due to the low feeding efficiency. And the temperature in the smelting furnace is higher, if shut down after, heat again and can consume a large amount of energy to smelting temperature, in whole recovery process, the smelting furnace is continuous operation, if pay-off efficiency is low, can lead to the smelting furnace empty time of burning long, causes the waste of the energy, and the cost of whole processing is higher moreover. Therefore, the inventor develops and improves the existing feeding device to form a high-efficiency feeding device.

Disclosure of Invention

The invention aims to provide an efficient feeding device to solve the problem that the existing feeding device is low in feeding efficiency.

In order to achieve the purpose, the invention provides the following technical scheme that the efficient feeding device comprises a base, an installation frame and a feeding bin arranged on the installation frame, wherein the feeding bin is communicated with a feeding chute, two side walls of the feeding bin, which are positioned at two sides of the feeding chute, are provided with vibrators, the two vibrators are parallel to each other and are positioned at the same position on the side walls of the feeding bin; the vibrator is obliquely arranged, and the inclination angle between the vibrator and the horizontal plane is 25-35 degrees; four groups of spring groups are arranged between the top of the feeding bin and the top of the mounting frame, and the four groups of spring groups are respectively positioned at four top corners of the feeding bin; the mounting bracket is fixed on the base.

In the process of actual production, the inventor finds that the feeding efficiency of the existing feeding device is low, and therefore the improvement is carried out based on the existing feeding device. When the inventor's first improvement, replaced the vibrator, chooseed the vibrator that vibration efficiency is higher for the vibrator takes place great vibration, with the pay-off efficiency that improves the material. But when using, because the amplitude grow of vibrator, the amplitude of pay-off storehouse also grow, the pay-off storehouse easily takes place the pine with the mounting bracket and takes place great striking, produces very big noise, and simultaneously, the promotion of pay-off efficiency is also not obvious.

Therefore, the inventor carries out research and development again, on the basis of the existing research and development, in order to realize efficient feeding, the inventor carries out inclined arrangement on the feeding bin, and when the vibrator is started, materials in the feeding bin can quickly fall along the inclined feeding bin, so that feeding is completed. However, a large amount of materials fall into the smelting furnace at the same time, so that the materials are tightly stacked in the smelting furnace, and the smelting effect is poor; and a large impact is generated on the smelting furnace, so that the smelting furnace is easy to damage.

Then, the inventor finds that the feeding efficiency is improved after the setting position of the vibrator is adjusted in the research and development process, researches are carried out on the position adjustment of the vibrator, the setting angle of the vibrator is determined, and the feeding effect is obviously improved when the inclination angle of the vibrator is set to be 25-35 degrees; and at the in-process of research and development, the inventor gets rid of the spring of bottom to test the damping effect, at the in-process of test, the discovery is compared original upper and lower position and all is set up the spring, only sets up the spring in upper portion, and the effect of pay-off can obtain great promotion.
