Description

Technical Field

[0001] The invention relates to the technical field of material cooling and conveying machinery, in particular to a steel belt type material cooling and conveying machine with a numerically controlled automatic deviation correction function. Background Art

[0002] A large number of high-temperature liquid molten products are produced in the production process of petrochemical refining and petrochemical industries, such as molten liquid sulfur recovered from desulfurization devices, molten liquid paraffin made from distillation devices, molten liquid petroleum resin made from high temperature and high pressure, and extracted high-temperature molten rosin resin, etc., all need to be cooled and formed into solid products that are convenient for storage and transportation. The cooling and forming of such products needs to be completed by steel belt cooling conveyors, in which the steel belt plays two key roles in this process: one is to cool the high-temperature molten liquid products into solid materials with relatively low temperatures, and the other is to transport the materials from one end of the conveyor to the other. Therefore, the working stability and reliability of the steel belt cooling conveyor and the effective working life of the steel belt are closely related to the production efficiency, product quality, daily maintenance workload and production cost of the granulator, and the closed-loop steel belt maintains a constant and appropriate tension on the drum and does not deviate from the position, which is the basic guarantee to ensure the continuous, stable and reliable operation of the steel belt conveyor. However, due to the load fatigue of the steel belt due to long-term work, the influence of the high-temperature material cooling on the steel belt itself, and the thermal expansion and contraction of the steel belt itself, the length of the steel belt will change to a certain extent and the length of the left and right sides will be unequal, which will cause the running position of the closed-loop steel belt on the drum to change accordingly. When the steel belt is heated, the length becomes longer, causing uneven speed, slippage and even displacement of the steel belt. When the steel belt is cooled and the temperature becomes lower, the length shortens, and the tension of the steel belt will be too large, causing plastic deformation of the steel belt and even displacement, affecting the normal operation of the material cooling conveyor and interfering with the automatic operation process of the steel belt material cooling conveyor. In recent years, a type of machine has appeared on the market that adds a manual tension adjustment mechanism with on-demand manual adjustment control function to the existing steel belt material cooling conveyor. Its basic structure is as follows: Figure 1As shown, the main body includes a frame 1, a drum 2 including a front driven drum 21 and a rear driving drum 22, a closed-loop steel belt 3 tightly sleeved on the drum 2, a right drum bearing seat 41 and a right bearing seat guide rail 51, and a left drum bearing seat 42 and a left bearing seat guide rail 52 symmetrically fixedly arranged on the left and right side frames of the frame 1 for limiting the installation of the left and right ends of the main shaft of the front driven drum 2 and guiding the displacement, respectively, a steel belt tensioning force right side adjusting mechanism 61 and a steel belt tensioning force left side adjusting mechanism 62 with the same structure symmetrically arranged between the right drum bearing seat 41 and the left drum bearing seat 42 of the front driven drum 21 and the left and right side frames of the frame, and a movable crossbeam 63 arranged between the steel belt tensioning force right side adjusting mechanism 61 and the steel belt tensioning force left side adjusting mechanism 62, wherein: the steel belt tensioning force right side adjusting mechanism 61 includes a limited position pressing plate A 611, a spring unit A 612 with a compression spring therein, and a main body extending through the spring unit A 612, one end of which is fixedly provided with the limit pressure plate A611, the middle part is screwed with a clamping nut A613, and the other end is supported by a threaded screw A614 on the right drum bearing seat 41; the left side adjustment mechanism 62 of the steel belt tensioning force comprises a limit pressure plate B621, a spring unit B622 with a compression spring, a main body extending through the spring unit B622, one end of which is fixedly provided with the limit pressure plate B621, the middle part is screwed with a clamping nut B623, and the other end is supported by a threaded screw B614 on the left drum bearing seat 42. 624; During operation, the operator can adjust the tension of the steel belt as needed according to the position of the steel belt. First, manually move the steel belt to the center position, and then adjust the position of the clamping nut A / B as needed, change the compression and elastic force of the spring unit A / B, and drive the elastic force to change the thrust of the threaded screw A / B on the left / right drum bearing seat, so that the left / right drum bearing seat is driven to shift forward and backward on the left / right bearing seat guide rail, thereby changing the relative position of the axis of the left / right drum bearing seat, and causing the axis position of the front driven drum 21 to shift, thereby realizing the lateral position adjustment control of the steel belt mounted on the front driving drum 21, and limiting the closed-loop steel belt 3 to the middle position of the front driven drum 21 under the traction of the moving crossbeam 65, which has certain practicality.However, it is found in practice that since the elastic force generated by the spring unit is non-constant under any limit condition, the tension of the steel belt generated after adjustment is only limited to the rated design range. The length and tension of the steel belt will change due to thermal expansion and contraction during operation. Although the thrust between the threaded screw and the drum bearing seat will also change accordingly, and the compression and elastic force of the spring unit will be changed accordingly, when the steel belt is long and the temperature of the steel belt changes too much, the length and expansion of the steel belt will often change greatly. At this time, the spring elastic force alone will not play any role. Manual intervention and real-time adjustment of the position of the clamping nut A / B are required to keep the steel belt within the rated range. Therefore, the operator needs to pay attention at all times, and the responsibility pressure is relatively high. Once the operator is not careful and fails to find that the steel belt is deviating, slipping, or wrinkling in time, it will still cause damage to the steel belt, affect the normal operation of the steel belt material cooling conveyor, increase the system shutdown maintenance frequency, workload and economic investment, and also affect the overall production efficiency of the automated operation system using the steel belt material cooling conveyor. Therefore, even if the existing steel belt material cooling conveyor is equipped with a manual tension adjustment mechanism, it still has many disadvantages such as unscientific and unreasonable structure, low degree of automation, poor working stability, large workload of daily maintenance, high cost of use and high pressure on operators. It is difficult to meet the continuous, stable, efficient and low-cost use requirements of the automated assembly line system. From the perspective of practicality and economy, it is less than ideal.
