Description

Technical Field

[0001] The utility model relates to the technical field of sodium sulfide calcination, in particular to a hammer device for sodium sulfide calcination. Background Art

[0002] When preparing sodium sulfide, coal powder reduction method is a common preparation method. In coal powder reduction method, mirabilite and coal powder are mixed in a ratio of 100: (21-22.5) (weight ratio) and calcined and reduced at a high temperature of 800-1100℃. After cooling, the product is dissolved into liquid with dilute alkali solution. After standing and clarifying, the upper concentrated alkali solution is concentrated to obtain solid sodium sulfide. After the transfer tank and flaking (or granulation), the sodium sulfide product in flake (or granule) form is obtained.

[0003] During the calcination process, a hammer device is needed to hammer the calcined material. The hammer mechanism in the traditional hammer device on the market is a single-pole hammer shaft. This design has the following disadvantages:

[0004] Single-axis hammering has poor hammering effect, which makes the calcined material large and difficult to melt, thus easily blocking the feed port. In addition, the hot melt extraction effect of large calcined material is poor, which affects the production quality of sodium sulfide to a certain extent, and is not conducive to its promotion and use.

[0005] Therefore, how to provide a hammer device for sodium sulfide calcination with good hammer effect has become a technical problem to be solved by those skilled in the art. Utility Model Content

[0006] The technical problem to be solved by the utility model is how to provide a hammering device for calcining sodium sulfide with good hammering effect.

[0007] To achieve the above-mentioned purpose, the utility model provides a hammer device for calcining sodium sulfide, comprising: a heat melter and a hammer mechanism. The left and right sides of the heat melter are open structures, correspondingly forming an input end and an output end of the calcined material. The hammer mechanism is arranged at the input end of the heat melter, and is used to perform a hammering process on the calcined material. Two hammer mechanisms are correspondingly arranged at the input end of the heat melter, and are vertically arranged between the two hammer mechanisms to form a double-axis spiral hammer function.

[0008] The hot melter adopts the existing structure on the market in this field, and is used to perform the hot melt extraction process on the calcined material. The calcined material enters the hot melter after the hammering process by the hammering mechanism. The two vertically arranged hammering mechanisms form a double-axis spiral hammering function, thereby improving the hammering effect of the device.

[0009] Preferably, the cross section of the output end of the hot fuser is a conical structure.

[0010] The inner wall of the output end of the conical structure of the hot melt is inclined, thereby forming a gathering and guiding function, and the output end of the hot melt is preset with two output ports (not shown in the figure), one of which is used to output the calcined material after hot melting, and the other is used to output the heat energy generated during calcination. This method is common knowledge and will not be repeated here.

[0011] Preferably, the output end of the hot melt device is connected with a connecting pipe.

[0012] The connecting pipe is used to discharge the heat energy generated during calcination and is also used to discharge the dust collected by the dust collection component.

[0013] Preferably, the hammer mechanism is a hammer shaft, and one end of the hammer shaft is connected to a preset driving source on the hot melter.

[0014] The driving source is composed of a motor and a reducer, which are not shown in the figure, and are used to drive the hammer shaft to rotate forward and reverse. This method is common knowledge and will not be described in detail.

[0015] Preferably, the hammer shaft is provided with hammer dices, and the hammer dices are symmetrically arranged at equal intervals on the hammer shaft.

[0016] The hammer dagger cooperates with the hammer shaft to hammer the calcined material, and the large pieces of calcined material are evenly broken into small pieces.

[0017] Preferably, the hammer shank and the hammer shaft are welded.

[0018] The welding design ensures the stability of the fixed connection between the hammer butt and the hammer shaft, which increases the service life of the hammer mechanism.

[0019] Preferably, the dust collecting assembly includes a dust collecting hood and a dust collecting duct.

[0020] The dust collecting component collects the dust generated when the hammer mechanism breaks and calcines the material, thus preventing the dust from flying everywhere, which reflects the environmental protection of the device.

[0021] Preferably, the dust collecting hood is installed at the input end of the hot melter, and the cross section of the dust collecting hood is a conical structure.

[0022] The dust collecting hood is fixedly connected to the input end of the hot melter, and the conical structure of the dust collecting hood allows dust to enter the hood body in the shape of the dust collecting hood, thereby greatly improving the dust collecting effect.

[0023] Preferably, the dust collecting pipe is installed on the top of the dust collecting hood, and the other end of the dust collecting pipe is connected to the connecting pipe.

[0024] The dust enters the connecting pipe through the dust collecting pipe, and is then discharged to the outside through the connecting pipe for subsequent processes.

[0025] The beneficial effects of the utility model are:

[0026] 1. When the utility model is in use, the two hammer mechanisms are arranged vertically to form a double-axis spiral hammer function, so that large pieces of calcined materials are evenly broken into small pieces by hammering, which greatly improves the hammer breaking efficiency. It not only avoids the problem of blockage, but also has a higher hot melt extraction effect of small pieces of calcined materials, thereby improving the production quality of sodium sulfide to a certain extent, which is conducive to its promotion and use.

[0027] 2. When the utility model is in use, the dust collecting assembly formed by the dust collecting hood and the dust collecting duct is used to collect the dust generated when the hammer mechanism is used to break and calcine the material, thereby preventing the dust from flying everywhere, which reflects the environmental protection of the device and complies with the existing environmental protection concept.
