Description

Technical Field

[0001] This utility model belongs to the field of sulfate-resistant cement production technology, and relates to a rotary hammer crusher for sulfate-resistant cement production. Background Technology

[0002] The existing sulfur-resistant cement production equipment suffers from drawbacks in rotary hammer crushing, primarily manifested in severe equipment wear, high energy consumption, high maintenance costs, and low production efficiency. These shortcomings stem from the high hardness and abrasiveness of sulfur-resistant cement raw materials, as well as limitations in the design of rotary hammer crushers, such as rotor speed, hammer material, and structural design, which fail to adequately meet the crushing requirements of high-hardness materials. Conventional solutions include using wear-resistant materials for hammers, increasing rotor speed to enhance crushing force, and regularly replacing and maintaining crusher components. However, these methods have drawbacks. While using wear-resistant materials can extend hammer lifespan, it is costly; increasing rotor speed, while improving crushing efficiency, also increases energy consumption and equipment wear, potentially affecting equipment stability and safety, reducing production efficiency, and increasing labor and time costs. Therefore, a rotary hammer crushing device for sulfur-resistant cement production is urgently needed to address these issues. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a rotary hammer crusher for sulfate cement production, thereby solving the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a rotary hammer crusher for the production of sulfate-resistant cement, comprising: a feed shell and a support frame, wherein the feed shell is provided with two sets of distribution chambers for introducing sulfate-resistant cement abrasive, the lower end of the distribution chamber is provided with a set of shells, the shells are provided with a set of crushing chambers for crushing sulfate-resistant cement abrasive, and the crushing chambers are provided with two sets of crushing components for crushing sulfate-resistant cement.

[0005] The crushing component includes a pulley and a movable chain. A set of rotating shafts is provided on the rear side of the pulleys. Several sets of connecting discs for connecting and fixing to the movable chain are provided on the outer side of the rotating shafts. The connecting discs are connected and fixed to the outer side of the rotating shafts by long bolts, and their positions are fixed by fixing nuts.

[0006] In a preferred embodiment, the front cross-section of each set of connecting discs is a circular structure, and several sets of movable chains for connecting and fixing to the rotating hammer are evenly distributed on the outer side of each set of connecting discs.

[0007] In a preferred embodiment, each set of movable chains is equipped with a set of rotating hammers for crushing sulfate-resistant cement abrasive. The rear side of the rotating shaft is equipped with a set of connectors for connecting to the motor. The outer side of the rotating hammers is equipped with an anti-abrasion coating. The operator needs to introduce the sulfate-resistant cement raw material through the feeding chamber and into the crushing chamber. Then, the operator starts two sets of motors, which drive a set of rotating shafts to rotate. The two sets of rotating shafts rotate in the same direction or rotate in opposite directions after the connecting belt is disconnected, thereby crushing the sulfate-resistant cement. The crushed material is fed into the conveyor belt through the bottom trough and is then led out by the conveyor belt. The rotating hammers and movable chains can change the crushing position, thereby achieving sulfate-resistant cement crushing operations at different sizes and positions.

[0008] In a preferred embodiment, a set of motors for driving the rotating shaft is provided on the rear side of the connector, and a set of bottom grooves for dropping sulfate-resistant cement abrasive fragments is provided at the lower end of the two sets of crushing components.

[0009] In a preferred embodiment, the lower end of the bottom trough is provided with a set of transmission belts for guiding sulfate-resistant cement abrasive fragments. The lower end of the crushing chamber is connected to the inside of the bottom trough. The outside of the motor is also provided with a set of fixing clips for maintaining its position.

[0010] In a preferred embodiment, the connecting discs inside the two sets of crushing components are staggered, and the outer sides of the pulleys of the two sets of crushing components are connected by several sets of connecting belts. The lower ends of the fixing clips on the front and rear sides are provided with a set of support frames for connecting and supporting them.

[0011] In a preferred embodiment, the outer side of the pulley is provided with a set of fixing clips for limiting its outer position. The lower end of the fixing clips is provided with a set of inner bearings for maintaining the stable rotation of the pulley. The material distribution chamber is provided with two sets, and the interior of both sets of material distribution chambers is interconnected with the interior of the shell. Since the low torque is relatively large during the crushing process of sulfate-resistant cement, when the motor drives the rotating shaft to rotate, the fixing clips can effectively limit the stability of the pulley and the motor, thereby reducing the impact of the hammer body on the crushing effect of sulfate-resistant cement by limiting the vibration during the crushing process.

[0012] In a preferred embodiment, the housing is composed of multiple metal plates joined together and fixed by bolts and several sets of latches. The left and right sides of the housing are each provided with four sets of latches for connection and fixation.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are as follows: the workers need to introduce the sulfate-resistant cement raw material through the feed chamber and into the crushing chamber. Then, the workers start two sets of motors, which drive a set of rotating shafts to rotate. The two sets of rotating shafts rotate in the same direction or disconnect the belt and rotate in opposite directions to carry out the sulfate-resistant cement crushing process. The crushed material is fed into the conveyor belt through the bottom trough and is led out by the conveyor belt. The rotating hammer and the movable chain can change the crushing position, thereby achieving sulfate-resistant cement crushing operations at different sizes. Because the low torque is large during the sulfate-resistant cement crushing process, the fixing clip can effectively limit the stability of the pulley and motor when the motor drives the rotating shaft to rotate, thereby reducing the vibration of the rotating hammer during the sulfate-resistant cement crushing process and affecting the crushing effect of the sulfate-resistant cement.
