With the advancement of cement production technology, clinker conveying equipment is also undergoing continuous technical improvements and innovations to improve conveying efficiency, reduce energy consumption, enhance equipment stability and safety, and reduce maintenance costs. Screw conveyors are enclosed conveying equipment that can effectively prevent the spillage and dusting of cement clinker.

[0003] The existing spiral conveying technology of cement clinker has slow heat dissipation and the waste heat of cement clinker is not fully utilized. The utility model solves the above problem. Utility Model Content

[0004] The utility model provides cement clinker conveying equipment in order to solve the technical problems in the prior art that the heat dissipation of cement clinker in spiral conveying is slow and the residual heat of cement clinker is not fully utilized.

[0005] The cement clinker conveying equipment includes: a conveying chamber, the bottom surface of the conveying chamber is a semicircular cross-section, a spiral hole is opened in the semicircular bottom surface, the upper part of the spiral hole is connected to a spiral tube, the spiral tube is connected to the inner wall of the conveying chamber, all the spiral holes and the spiral tube form a spiral channel, the spiral channel is connected to the inlet pipe and the outlet pipe at both ends, a feed port is opened on the top wall of the conveying chamber at the inlet pipe end, a conveying shaft is rotatably connected to the side wall of the conveying chamber, a stirring blade is connected to the conveying shaft, a hole is provided on the stirring blade, the stirring blade is a spiral blade and the pitch is greater than the length of the conveying chamber, the conveying shaft, the spiral channel and the semicircular bottom surface of the conveying chamber are concentrically arranged, and a discharge port is opened on the side of the conveying chamber.

[0006] Furthermore, the top wall of the conveying chamber is provided with an air inlet, and multiple groups of air inlets are provided along the length of the conveying chamber. A wind hood is fastened to the outside of each group of air inlets, and the wind hood is connected to the top wall of the conveying chamber. The wind hood is connected to the air inlet pipe, and the air inlet pipe is connected to the fan.

[0007] Furthermore, the air inlet is opened obliquely from top to bottom toward the discharge port.

[0008] Beneficial effects of the utility model:

[0009] The cement clinker is transported by the spiral stirring blades in conjunction with the conveying chamber. Since the stirring blade pitch is greater than the conveying chamber length and is provided with holes, the stirring blade drives the cement clinker to turn evenly while conveying. Cooling water flows through the spiral channel, and the heat of the evenly turned clinker is taken away by the cooling water, achieving simultaneous cooling during conveying. The hot water that absorbs the waste heat can also be used in industry and daily life.

[0010] The air inlet is tilted toward the discharge port to blow air, which helps to improve the cooling effect while conveying. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] The rotational connection described in this device refers to the process of baking the bearing on the shaft, providing a spring retaining ring groove on the shaft or the shaft hole, and clamping the elastic retaining ring in the retaining ring groove to achieve axial fixation of the bearing and realize rotation; the articulation refers to a connection method that is achieved by performing activities on connecting parts such as hinges, pins and short shafts.

[0017] The present invention will be described in detail below with reference to the accompanying drawings. Example

[0018] The following is combined with Figure 1 -Description of the cement clinker conveying equipment of this embodiment, comprising: a conveying chamber 1, the bottom surface of the conveying chamber 1 is a semicircular cross-section, a spiral hole 2 is opened in the semicircular bottom surface, the upper part of the spiral hole 2 is connected to a spiral tube 3, the spiral tube 3 is connected to the inner wall of the conveying chamber 1, all the spiral holes 2 and the spiral tube 3 form a spiral channel, the spiral channel is connected to a liquid inlet pipe 4 and a liquid discharge pipe 5 at both ends, a feed port 6 is opened on the top wall of the conveying chamber 1 at the end of the liquid inlet pipe 4, a conveying shaft 7 is rotatably connected to the side wall of the conveying chamber 1, a stirring blade 8 is connected to the conveying shaft 7, a hole is provided on the stirring blade 8, the stirring blade 8 is a spiral blade and the pitch is greater than the length of the conveying chamber 1, the conveying shaft 7, the spiral channel and the semicircular bottom surface of the conveying chamber 1 are concentrically arranged, and a discharge port 9 is opened on the side of the conveying chamber 1;

[0019] The cement clinker discharged from the rotary kiln enters the conveying chamber 1 through the feed port 6. The power of the conveying shaft 7 is turned on, and the conveying shaft 7 drives the stirring blade 8 to move. Since the stirring blade 8 is a spiral blade and the pitch is greater than the length of the conveying chamber 1, the stirring blade 8 can flip the clinker while conveying the clinker. Since there are holes on the stirring blade 8, the flipped clinker falls through the stirring blade 8, making the clinker on the stirring blade 8 gradually thinner, slowing down the conveying speed while fully contacting with the air to reduce the temperature. Cooling water is injected through the liquid inlet pipe 4, and the cooling water enters the spiral channel formed by the spiral hole 2 and the spiral tube 3, taking away the heat in the air and the bottom wall of the conveying chamber 1, and discharged through the drain pipe 5 to cool the cement clinker. The hot water that absorbs the waste heat is also used in industry and life.

[0020] An air inlet 10 is provided on the top wall of the conveying chamber 1. There are multiple groups of air inlets 10 along the length of the conveying chamber 1. A wind cover 11 is fastened to the outside of each group of air inlets 10. The wind cover 11 is connected to the top wall of the conveying chamber 1. The wind cover 11 is connected to the air inlet pipe 12, and the air inlet pipe 12 is connected to the fan.

[0021] Air is blown through the air inlet pipe 12 of the fan box, and the external air enters the conveying chamber 1 through the air cover 11 and the air inlet 10 to blow toward the cement clinker, taking away the heat of the clinker.

[0022] The air inlet 10 is opened from top to bottom in an inclined direction toward the discharge port 9;

[0023] External air is sprayed out obliquely through the air inlet 10, guiding the clinker toward the discharge port 9. Since there is no need to worry about clinker backflow, the fan can be turned on at a higher power, resulting in a better cooling effect.
