Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of building material production equipment, specifically designs a kind of rotary kiln for new building material production. BACKGROUND

[0002] With the increasingly high requirement of low-carbon environmental protection for industrial production, how to treat carbon dioxide in industrial flue gas has become a key problem, the applicant uses a new material that can react with carbon dioxide to produce building materials, which can react and absorb carbon dioxide during the process of processing into finished building materials to improve the quality of building materials. Using this material to produce building materials can not only obtain high-quality products, but also consume a large amount of carbon dioxide, so that the carbon dioxide in industrial flue gas is effectively treated, and the carbon dioxide emission in the air is reduced. The above-mentioned material is in powder form, and during the processing process, it is necessary to maximize the reaction of the powder material under the pressure of +60kpa of water and carbon dioxide, and it is necessary to reach the clay state that meets the shaping conditions. Therefore, slow and soft kneading is required during mixing, and sufficient contact between water, carbon dioxide and material is required. At present, there is no equipment for this process in the existing equipment.

[0003] Therefore, a device for fully mixing powder material and carbon dioxide under positive pressure is needed. CONTENT OF THE UTILITY MODEL

[0004] To solve the above problems, the utility model provides a kind of rotary kiln for new building material production, including:

[0005] Kiln body, kiln body includes rotating mechanism, rotating mechanism inside is provided with the material cavity for containing material, the both ends of rotating mechanism are connected with sealing mechanism, sealing mechanism covers and seals the both ends of rotating mechanism and is fixed relative to ground;Rotating mechanism can be the open-ended cylindrical container, and the space in the cylinder is the material cavity;

[0006] Material conveying assembly, material conveying assembly includes feed inlet, feed inlet is connected with sealing mechanism, material conveying assembly further includes water channel and flue gas channel, water channel and flue gas channel are connected with sealing mechanism and are fixed relative to sealing mechanism, water channel and flue gas channel are connected with material cavity;

[0007] Rotary assembly, rotary assembly is connected with rotating mechanism, for driving rotating mechanism to rotate around its own center axis;

[0008] Pressure sensor is arranged in material cavity, pressure sensor is connected with control assembly, gas outlet is arranged on sealing mechanism, valve is arranged on gas outlet, valve is connected with control assembly, and valve is electric valve, and valve can be flow valve.

[0009] The rotating assembly drives the rotating mechanism to rotate slowly, which is used to knead the material. The sealing mechanism remains stationary, and the sealing mechanism and the feeding assembly connected to the sealing mechanism do not rotate with the rotating mechanism. The slow rotation is to make the material always roll at the bottom of the rotating mechanism. The water channel and the flue gas channel continuously introduce water and flue gas slowly, and the pressure increases to about +60kpa. When the pressure sensor exceeds +65kpa, the control assembly opens the valve of the gas outlet. When the pressure reaches about +60kpa, the valve is closed again. The material and water slowly mix and react with the carbon dioxide in the flue gas until the material is kneaded into clay.

[0010] The discharge of water and flue gas is controlled by the control assembly. The amount of material, water, and flue gas entering is discharged according to the set program. This is a well-known technology in the field, and therefore will not be described here.

[0011] Preferably, the sealing mechanism includes a slewing bearing, one end of the slewing bearing is connected to the rotating mechanism, a slewing seal is provided at the connection between the slewing bearing and the rotating mechanism, and the other end of the slewing bearing is connected to a cover. The water channel and the flue gas channel are fixed to the cover. The slewing bearing can realize the fixation of the sealing mechanism when the rotating mechanism rotates, and the two are fixedly connected. The slewing seal ensures the air tightness in the material cavity.

[0012] Preferably, the water channel and / or the flue gas channel are arranged along the axis direction of the rotating mechanism. One end of the water channel and / or the flue gas channel is open for connecting the water source and / or the gas source. A plurality of nozzles are provided on the side wall of the water channel. The water in the water channel enters the material cavity through the nozzles. A plurality of through holes are provided on the side wall of the flue gas channel. The flue gas is discharged into the material cavity through the through holes. The water is uniformly sprayed onto the material through the nozzles. The water channel and the flue gas channel are always located above the material cavity. One end of the water channel / flue gas channel is connected to the gas source, and the other end is closed, which ensures that the water / flue gas is discharged into the material cavity through the nozzles / through holes.

[0013] Preferably, the two ends of the water channel and / or the flue gas channel are fixed to the sealing mechanisms at the two ends of the rotating mechanism. If the length of the rotating mechanism is too large, the length of the required water channel and flue gas channel will increase accordingly. At this time, fixing the two ends of the water channel and the flue gas channel to the sealing mechanisms can prevent the channel from bending, making the fixation more secure. It also makes the contact between the water channel and / or the flue gas channel and the sealing mechanism uniform, reducing the damage of the flue gas / water channel and the sealing mechanism.

[0014] Alternatively, one end of the water channel and / or the flue gas channel connected to the water source and / or the gas source is fixed to the sealing mechanism, and the other end is suspended. If the length of the rotating mechanism is relatively short, one end of the water channel and / or the flue gas channel can be fixed to the sealing mechanism. The water channel / flue gas channel itself needs to have a certain hardness.

[0015] Preferably, the water channel and / or the flue gas channel is provided with a sealing element at the connection with the sealing mechanism, and the water channel and / or the flue gas channel can be connected with the sealing mechanism by a non-detachable connection such as welding, or a detachable connection which facilitates replacement of the water channel and / or the flue gas channel or disassembly for cleaning.

[0016] Preferably, the sealing element is a heat-resistant elastic sleeve structure such as a polyurethane sleeve, and the sealing element is used to seal the gap between the water channel and / or the flue gas channel and the sealing mechanism; since the flue gas entering is at a certain temperature, a sealing element that is not heat-resistant can be damaged by long-term heating and the sealing effect is weakened; the use of an elastic sealing element, which is fixed to the sealing mechanism, and the water channel and / or the flue gas channel are connected with the sealing element by interference fit, which is simple and has high air tightness.

[0017] Preferably, the inner wall of the rotating mechanism is provided with a plurality of stirring elements, which are beneficial to increase the uniform mixing of the material and carbon dioxide, but the edges of the stirring elements should be relatively smooth, and too sharp stirring elements can pierce into the material under the action of pressure, which is not conducive to the kneading of the clay into a brick embryo.

[0018] Preferably, the side of the rotating mechanism away from the feed inlet is provided with a discharge port, and the central axis of the rotating mechanism is inclined along the horizontal direction to the end with the discharge port, that is, the central axis of the rotating mechanism forms an angle with the horizontal direction, and the opening direction of the angle extends away from the discharge port. This arrangement facilitates the movement of the material in the kneading process towards the discharge port, and facilitates the discharge of the material after stirring is completed.

[0019] Preferably, the rotating assembly includes a motor connected with a driving gear, the outer wall of the rotating mechanism is provided with a driven gear, and the driving gear and the driven gear are connected by a chain; any other rotating assembly that can drive the rotating mechanism to rotate can also be used.

[0020] Preferably, the rotating mechanism is connected with a rotating wheel, and the rotating wheel can assist the rotation of the rotating mechanism; the rotating wheel is connected with a support, and the support is connected with universal wheels, which can facilitate the movement of the rotary kiln.

[0021] The beneficial effects of the present application are as follows:

[0022] 1. The sealing mechanism is provided at both ends of the rotating mechanism, so that the mixing process is always maintained in a positive pressure environment, providing the necessary conditions for the reaction of carbon dioxide and material, while producing high-quality building materials, consuming carbon dioxide in flue gas, and contributing to low-carbon environmental protection.

[0023] 2. The water channel and the flue gas channel are both arranged as point spray type, the sprayed flue gas and water are more fine, the contact area among the flue gas, water and material is increased, the carbon dioxide is reacted to the maximum extent, and the reaction effect is improved.

[0024] 3. The stirring piece is arranged as a triangular prism, and the inclined surface is beneficial to the material falling off from the stirring piece, and prevents the material from being taken to a high place by the stirring piece in the stirring process, if the material falls off from the high place, the kneaded material will be scattered again, which is not beneficial to the material forming.
