Abstract
Description
Technical Field
[0001] The utility model relates to a material discharging screener for a suspension calcining system. Background Art
[0002] In recent years, with the popularization of new dry cement production technology, the core suspension calcination technology has gradually begun to be applied in other inorganic salt industries. Different from the traditional rotary kiln calcination system with long reaction time and low thermal efficiency, the suspension calcination technology grinds the material and uses the fan to drive the material to be fully dispersed in the calcination furnace, which greatly increases the reaction area and greatly improves the reaction speed in the furnace. The suspension calcination technology is mainly composed of a multi-stage suspension preheater, a suspension calcination furnace, and a multi-stage suspension cooler. The materials output by the suspension calcination system are mainly powdered materials, but there are block materials such as detached furnace crust, sintered agglomerate materials, and burner coke in the system. In order to ensure the quality of the finished product, the calcination system output needs to be sorted.
[0003] Since the materials in the suspension calcining system are dispersed by the airflow, there is basically no sintering, which is suitable for processes that do not require sintering reactions. Since the materials are basically not sintered, the system discharges mainly powder materials, so a layer of grid plate can be added at the discharge port to achieve the purpose of separating powder materials and lump materials.
[0004] Although a simple layer of grid plate can separate powder and block materials, it lacks cleaning means and is prone to clogging the discharge port due to a large amount of block materials in a short period of time. Summary of the invention
[0005] In view of the above reasons, the utility model provides a discharging screener for a suspension calcining system, which redesigns the discharging device and changes the horizontally arranged screen to an inclined arrangement, thereby increasing the screen area and facilitating the discharge of intercepted block materials.
[0006] The technical solutions adopted in this utility model are:
[0007] A discharge screener for a suspended calcining system comprises a shell and a sieve plate, wherein the shell is provided with a feed port and two discharge cavities, wherein one discharge cavity is arranged vertically and the other discharge cavity is arranged obliquely, the sieve plate is obliquely plugged into the shell and placed in the vertical discharge cavity, the end of the sieve plate extends into the inclined discharge cavity, a monitoring port is provided on the outer wall of the shell, and the outer end of the sieve plate is placed in the monitoring port.
[0008] Furthermore, the sieve plate includes a rectangular frame and sieve rods, a plurality of sieve rods are fixed in parallel in the rectangular frame, an insert rib is provided on the outer wall of the rectangular frame, and a slot matched with the insert rib is provided on the inner wall of the shell.
[0009] Furthermore, a step surface for positioning the screen plate is provided on the cavity wall of the inclined discharge cavity.
[0010] Furthermore, a notch protruding outward is provided on the outer wall of the shell, the notch forms a monitoring port, and a sealing plate is fixed at the outer opening of the monitoring port.
[0011] The utility model has the following beneficial effects:
[0012] The utility model has a simple structure and good separation effect. The mixed material is fed from the upper part of the screener, the screen plate intercepts the block material and falls into the discharge port on one side, and the powder material continues to go down and enters the finished product conveying equipment. If the screen plate is damaged after a period of use, it is only necessary to open the sealing plate and remove the screen plate 2 to remove the damaged screen plate and replace it. Due to the inclined design of the screen plate, the intercepted block material will not stay on the screen plate but will roll down to the other side outlet along the screen plate under the action of gravity, which ensures the smooth passage of the material inside the screener to the greatest extent. At the same time, the screen plate is arranged obliquely to prevent the material from arching. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The utility model is further described below in conjunction with the accompanying drawings.
[0018] like Figures 1 to 4 The utility model discloses a discharge screener for a suspended calcining system, comprising a shell 1 and a sieve plate 2. The shell 1 is provided with a feed port and two discharge chambers, one of which is arranged vertically and the other is arranged obliquely. The sieve plate 2 is obliquely plugged into the shell 1 and placed in the vertical discharge chamber. The end of the sieve plate 2 extends into the inclined discharge chamber. A monitoring port 3 is provided on the outer wall of the shell 1, and the outer end of the sieve plate 2 is placed in the monitoring port 3.
[0019] The sieve plate 2 in the utility model comprises a rectangular frame 21 and sieve rods 22. A plurality of sieve rods 22 are fixed in parallel in the rectangular frame 21. To facilitate the stable insertion of the sieve plate 2 in the housing 1, a dowel 23 is provided on the outer wall of the rectangular frame 21, and a slot matching the dowel 23 is provided on the inner wall of the housing 1. To facilitate the positioning of the sieve plate 2 on the housing 1, a step surface for positioning the sieve plate 2 is provided on the wall of the inclined discharge cavity.
[0020] An outwardly protruding notch is provided on the outer wall of the housing 1, and the notch forms a monitoring port 3, and a sealing plate is fixed at the outer opening of the monitoring port 3. The sieve plate 2 is sealed in the monitoring port 3, which is safer to use.
[0021] The sieve plate is inserted into the screener through the monitoring port (also called the inspection port) on one side of the shell. The sieve plate is easy to replace. Due to the inclined arrangement of the sieve plate, the block material will roll along the sieve plate to the discharge port on one side, and the powder material will fall vertically into the discharge port on the other side.
[0022] The utility model has a simple structure and good separation effect. The mixed material is fed from the upper part of the screener, the screen plate intercepts the block material and falls into the discharge port on one side, and the powder material continues to go down and enters the finished product conveying equipment. If the screen plate is damaged after a period of use, it is only necessary to open the sealing plate and remove the screen plate 2 to remove the damaged screen plate and replace it. Due to the inclined design of the screen plate, the intercepted block material will not stay on the screen plate but will roll down to the other side outlet along the screen plate under the action of gravity, which ensures the smooth passage of the material inside the screener to the greatest extent. At the same time, the screen plate is arranged obliquely to prevent the material from arching.
[0023] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be regarded as within the protection scope of the present invention.
