Description

Technical Field

[0001] The utility model relates to the technical field of composite brick cooling, in particular to a cooling device used for composite brick production. Background Art

[0002] Composite bricks are a type of building bricks. They consist of an inner core and an outer shell. The inner core is a solid body made of low-strength materials, such as cement expanded perlite; the outer shell is made of high-strength materials, such as cement mortar. After being fired, composite bricks need to be cooled by a cooling device during production to make them a processable product.

[0003] The Chinese patent "A rapid cooling device for light refractory composite bricks" authorization announcement number "CN 215571434U" uses multiple sets of blowers at the top and bottom to blow air to the top and bottom of the composite bricks that have just been washed and cooled, accelerating the air flow and allowing the moisture on the surface of the composite bricks to evaporate quickly.

[0004] However, the water droplets at the bottom of the composite bricks will enter the blower at the bottom. The water droplets entering the blower may cause corrosion or short circuit of the motor and other electrical components, thereby damaging the internal structure of the blower, affecting its normal operation, and further affecting the cooling effect on the composite bricks.

[0005] Therefore, a cooling device for composite brick production is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a cooling device for composite brick production in order to solve the above-mentioned problem, thereby improving the problem that water drops at the bottom of the composite bricks will enter the bottom blower, thereby reducing the service life of the blower.

[0007] The utility model achieves the above-mentioned purpose through the following technical solutions. A cooling device for composite brick production comprises: a working frame, both sides of the inner wall of the working frame are rotatably connected with pulleys, and the surface of the working frame is provided with a blocking mechanism; wherein the blocking mechanism comprises a blower fixedly connected to the rear end of the working frame, one end of the blower is connected with a conveying pipe, and one end of the conveying pipe is connected with two air jet pipes, one of which has a one-way valve on its surface, and a driving assembly is provided at the front end of the working frame, and the air jet pipe interacts with the one-way valve to block water droplets at the bottom of the composite brick from flowing into the blower, thereby ensuring the service life of the blower and the cooling effect on the composite brick.

[0008] Preferably, the driving assembly includes a driven gear fixedly connected to one end of one of the air jet pipes, the surface of the driven gear is meshingly connected with a rack, and the reciprocating movement of the rack drives the corresponding air jet pipe to swing back and forth through the driven gear. The air jet pipe reduces the amount of water droplets at the bottom of the composite brick flowing into the air jet pipe during the reciprocating swing, avoids the air outlet of the air jet pipe pointing vertically upward, and increases the amount of water droplets flowing into the air jet pipe.

[0009] Preferably, one side of the rack is fixedly connected to a slide, and a reciprocating screw is provided at the front end of the working frame, and the surface of the reciprocating screw is provided on the inner wall of the slide, and one end of one of the pulleys is fixedly connected to a first bevel gear, and one end of the first bevel gear is meshingly connected to a second bevel gear, and one end of the second bevel gear is fixedly connected to one end of the reciprocating screw, and the rotation of the corresponding pulley drives the reciprocating screw to rotate through the first bevel gear and the second bevel gear, and the rotation of the reciprocating screw can drive the corresponding air spray pipe to swing back and forth through the slide, the rack and the driven gear.

[0010] Preferably, a sliding rod is provided at the front end of the working frame, and the inner wall of the slide is slidably connected to the surface of the sliding rod. The sliding rod limits the moving slide to prevent the reciprocating screw from rotating and causing the slide to move back and forth and cause deviation.

[0011] Preferably, the front end of the working frame is fixedly connected to a fixed block, one end of the sliding rod is fixedly connected to one side of the fixed block, one end of the reciprocating screw is rotatably connected to the inner wall of the fixed block, and the fixed block is used to support and limit the reciprocating screw and the sliding rod to ensure that the reciprocating screw can rotate normally and the sliding rod can limit the slide normally.

[0012] Preferably, a sealed bearing is fixedly connected to the inner wall of one of the air jet pipes, and the inner edge of the sealed bearing is fixedly connected to the surface of the conveying pipe. The sealed bearing ensures that the corresponding air jet pipe will not drive the conveying pipe to rotate during rotation, thereby reducing the wear rate of the conveying pipe.

[0013] The beneficial effects of the utility model are:

[0014] The air generated by the blower is transported to two air jet pipes through the conveying pipes. One of the pulleys rotates through the first bevel gear, the second bevel gear, the reciprocating screw, the slide, the rack and the driven gear to drive the corresponding air jet pipe to swing back and forth and dry the bottom of the composite brick. The air jet pipe reduces the amount of water droplets at the bottom of the composite brick flowing into the air jet pipe during the reciprocating swing, avoids the air outlet of the air jet pipe pointing vertically upward, and increases the amount of water droplets flowing into the air jet pipe. The air jet pipe interacts with the one-way valve to prevent the water droplets at the bottom of the composite brick from flowing into the blower, thereby ensuring the service life of the blower and the cooling effect on the composite brick.

[0015] The slide rod limits the moving slide to prevent the reciprocating screw from causing the slide to deviate during reciprocating movement. The fixed block is used to support and limit the reciprocating screw and the slide rod to ensure that the reciprocating screw can rotate normally. The slide rod can limit the slide normally. The sealed bearing ensures that the corresponding air spray pipe will not drive the conveying pipe to rotate during rotation, thereby reducing the wear rate of the conveying pipe.

The reciprocating screw 3054 is in the form of two thread grooves with the same pitch and opposite rotation directions, and the two ends are connected by a transition curve. Through the rotation of the screw, the side of the spiral groove pushes the slide 3053 placed in the spiral groove to make axial reciprocating motion.);

[0024] When it is necessary to dry the top and bottom of the moving composite brick, start the blower 303. The blower 303 generates wind, which is transported to the two air injection pipes 301 through the conveying pipe 302. The rotation of one of the pulleys 2 drives the first bevel gear 3056 to rotate. The rotation of the first bevel gear 3056 drives the second bevel gear 3055 to rotate slowly (the diameter of the second bevel gear 3055 is several times the diameter of the first bevel gear 3056. The specific gear diameter ratio is selected according to actual conditions). The rotation of the second bevel gear 3055 drives the reciprocating screw 3054 to rotate.
