Description

Automatic hammer crusher capable of automatically starting and stopping

Technical Field

The utility model relates to the technical field of crushers, in particular to an automatic hammer crusher capable of automatically starting and stopping.

Background

Hammer mills are a common industrial crushing apparatus which is used primarily for crushing, pulverizing or fine crushing larger materials with rotating hammers or cutters. It generally consists of a rotating spindle and a hammer or cutter mounted on the spindle. When the material is fed into the feed port of the pulverizer, the rotating spindle causes the hammer or cutter to rotate at high speed to produce impact and shear forces. The material is impacted and broken into smaller particles by contact with a rotating hammer or cutter through a feed system. These hammers or cutters may be mounted on the disk of the spindle and fixed to the edge of the disk or mounted directly on the spindle. Hammer mill is widely used in metallurgical, chemical, building materials, mine and other industries for treating various solid materials, such as ore, rock, timber, waste, etc. Their efficacy typically includes crushing, fine grinding, granulation, recycling, and the like. The existing rotor for the novel pulverizer and the novel pulverizer (publication number: CN 206519206U) at least expose the following defects in use:

1. when an operator carries out manual feeding, the feeding of materials needs to be controlled and monitored manually. This increases the complexity and labor costs of operation and may lead to reduced production efficiency, difficulty in achieving accurate material delivery control, and may lead to unsatisfactory comminution results or failure to meet the processing requirements of the particular material. Manual feeding may present a certain safety risk, especially for some larger or potentially dangerous materials. The operator needs to access the rotating hammer blade and the running equipment, increasing the risk of injury. Therefore, there is a need for a hammer mill that can be automatically charged and started and stopped.

2. Because of the inability to detect failure of the internal spindle, operators often cannot immediately know when a problem occurs with the spindle. This may result in continued operation of the device in the fault condition, further damaging the device, increasing repair and maintenance costs. If the inner spindle fails, maintenance or replacement is required. Because the fault cannot be detected in time, the operator may take more time and effort to troubleshoot the cause of the fault and determine maintenance measures. This can result in extended production downtime, increasing repair and maintenance costs. Continued operation may increase the safety risk of the device if the internal spindle fails but is not timely detected. Failure of the spindle may cause abnormal operation, sway or unbalance of the apparatus, thereby causing vibration, noise or even breakage of the apparatus, which may present a hazard to the operator and the surrounding environment. Therefore, there is a need for a hammer mill that automatically alarms for spindle failure.

3. Excessive or unstable vibrations can cause additional loads to the structure and components of the device, resulting in fatigue failure and damage. Vibration has long been a potential for reducing the life of equipment and increasing the frequency and cost of repair and replacement of parts. Vibration can influence effective contact and collision between hammer leaf and the material, and then influences crushing effect. Excessive vibration may result in uneven material distribution and crushing, reducing consistency in quality and specification of the produced material. The large amplitude of vibration is transmitted to the environment surrounding the device, causing noise and vibration. This can have a negative impact on the health and comfort of the staff and even on the stability of the surrounding equipment or structures. Excessive vibration may cause the device to loosen or become unbalanced, increasing the risk of accidents. For example, shifting, falling or tipping of the device may cause injury to operators and maintenance personnel. Therefore, there is a need for a vibration-damped hammer mill.

Examples

Referring to fig. 1-4, the present utility model provides a technical solution:

automatic change hammer mill that stops from opening, including crusher housing 1, its characterized in that: install spindle 2 in the pulverizer housing 1, install rotational speed detector 3 on the spindle 2, install disc 4 on the spindle 2, install hammer mounting bearing 5 on the disc 4, install hammer 6 on the hammer mounting bearing 5, spindle 2 installs rotation motor 20 on the pulverizer housing 1, pulverizer housing 1 internally mounted material detector 7, pulverizer housing 1 upper portion is connected feed channel 8, feed channel 8 is inside to have conveyer belt 9, conveyer belt 9 below installation transmission control module 21 and transport motor 22, pulverizer housing 1 externally mounted alarm 10 and alarm control module 11, pulverizer housing 1 and feed channel 8's junction installation control valve 12, pulverizer housing 1 lower part installation ejection of compact baffle 13, pulverizer housing 1 lower part has support 14 to support, support 14 below installation bumper shock absorber 15.

The rotation speed detector 3 is externally provided with a protective shell 31, and the rotation speed detector 3, the rotating motor 20 and the alarm control module 11 are connected with the alarm 10 through wires and a power supply.

The material detector 7, the conveying control module 21 and the conveying motor 22 are connected with the conveying belt 9 through wires.

The hammer mounting bearing 5 is mounted on the disc 4 by screws 16.

The feed channel 8 is connected with the pulverizer housing 1 via a mounting plate 17 and a mounting screw 18.

Four damping springs 19 are arranged inside the damper 15.

In this embodiment, the material detector 7 is installed inside the crusher housing 1, the upper portion of the crusher housing 1 is connected with the feeding channel 8, the conveyor belt 9 is disposed inside the feeding channel 8, the transmission control module 21 and the transmission motor 22 are installed below the conveyor belt 9, and the material detector 7, the transmission control module 21, the transmission motor 22 and the conveyor belt 9 are connected through wires. When the material is small, if automatic feeding is not performed, an operator needs to manually add the material, which may cause a reduction in downtime and productivity. And through automatic feeding, the downtime can be reduced, and the production efficiency is improved. The traditional manual material adding method requires operators to monitor and intervene, and after automatic feeding is adopted, the dependence on operators can be reduced, human resources are saved, and incorrect operation caused by human factors is avoided. For example, if the manual addition of material takes 10 minutes per hour, which would save about 80 minutes of working time if working for 8 hours per day. The automatic feeding can accurately control the supply quantity of materials, and avoid the occurrence of excessive or insufficient conditions, thereby reducing the waste and loss of the materials and the running cost. Assuming that a 30 minute clean up is required per equipment jam shutdown per normal operating conditions, which occurs on average 3 times a week, a 90 minute clean up time per week can be saved. The conveyor belt automatic feeding can avoid operators from contacting dangerous equipment such as a crusher and the like in the production process, so that accident risks are reduced, and the working safety is improved.

In this embodiment, the main shaft 2 is installed in the pulverizer housing 1, the rotation speed detector 3 is installed on the main shaft 2, the alarm 10 and the alarm control module 11 are installed outside the pulverizer housing 1, the protective housing 31 is installed outside the rotation speed detector 3, and the rotation speed detector 3, the rotation motor 20, and the alarm control module 11 are connected with the alarm 10 through wires and a power supply. The rotational speed detector may monitor the rotational speed of the spindle. Upon occurrence of a fault or abnormal condition, such as an excessive or insufficient rotational speed, the rotational speed detector is immediately able to sense and trigger an alarm device. Therefore, faults can be found in time, further damage to equipment is avoided, and maintenance cost is reduced. Abnormal spindle speeds may lead to unbalance, breakage or other serious malfunction of the equipment, even causing dangerous accidents. By activating the alarm device, an operator or related personnel can be informed in time to take necessary measures, such as shutdown maintenance or emergency maintenance, to avoid potential equipment accidents and personal injuries. Too high or too low a rotational speed of the spindle may cause additional loads and wear on the components of the apparatus, shortening the life of the apparatus. Through timely finding the fault and stopping for repair, the equipment can be prevented from running continuously at abnormal rotating speed, the service life of the equipment is effectively prolonged, and the cost of maintaining and replacing parts is reduced. When a fault occurs, the alarm device is started in time to rapidly stop and maintain, so that the production stopping time is reduced, and the production efficiency is improved. Avoiding energy waste and production loss caused by long-time ineffective operation. Too high or too low rotational speed may indicate mechanical failure or failure, and the activation of the alarm device may allow an operator to stop the operation of the apparatus in time, preventing a possible safety accident. According to statistics, the industrial case caused by equipment failure accounts for about 20% of all industrial cases. The abnormal condition of the machine can be timely detected and repaired through the rotating speed detector, and equipment damage caused by incorrect operation or long-time running due to faults is prevented. For example, the average cost of equipment damage per repair is 3000 yuan, and the equipment damage is required to be repaired 2 times a year, so 6000 yuan of equipment maintenance cost can be saved each year. Because the fault can be found and repaired in time, long-time shutdown and repair time are avoided, and the production efficiency is improved. For example, if an average of 2 hours is required for a plant failure to be repaired every time a shutdown, and an average of 12 failures occur a year, 24 hours of plant downtime can be saved each year. The equipment failure can produce unqualified or dangerous materials, can timely detect and stop, and can protect subsequent equipment and procedures. This will reduce the risk and cost of the overall production line.

In this embodiment, the lower part of the pulverizer housing 1 is supported by a support 14, a damper 15 is installed below the support 14, and four damper springs 19 are arranged inside the damper 15. The shock absorber is an ALJ-01 type damping spring shock absorber of An Lijing. The damping spring shock absorber adopts the design of combining the spring and the damper, can generate relatively large damping effect, and absorbs the vibration energy of a mechanical system, thereby playing a good role in damping. Compared with the common spring shock absorber and the common hydraulic shock absorber, the damping spring shock absorber has more excellent shock absorption effect. The damping spring shock absorber is made of high-strength metal or steel generally, has good durability and corrosion resistance, is not easy to damage or malfunction in long-term use, and effectively protects the stability and normal operation of mechanical equipment. The damping spring damper has small volume, light weight and simple installation, and is suitable for damping of a plurality of light mechanical devices. The vibration damper is effective in reducing vibration of the pulverizer from being transmitted to the ground or other equipment. They absorb and disperse vibration energy, reducing the range of noise and vibration propagation, and reducing interference with the surrounding environment and other equipment. After the shock absorber is arranged at the bottom of the pulverizer, the stability of equipment can be improved. They act as a buffer, dampen vibrations, and stabilize the position of the device during operation, thereby reducing the problem of shaking and instability of the device due to vibrations. The use of vibration dampers reduces the transmission of vibrations of the mill to surrounding structures and foundations, reducing the risk of damage to the building or equipment structure. Meanwhile, the shock absorber also provides a more stable working platform, reduces the vibration influence of operators in the working process, and improves the safety of the working environment. The shock absorber can effectively absorb shock generated when the equipment is operated, and the potential mechanical failure risk can be reduced. Assuming that the equipment failure caused by vibration is 4 times per year on average, the repair cost is 3000 yuan each time, and after the shock absorber is used, the failure rate is reduced by 50%, which means that 6000 yuan can be saved in the annual repair cost. The equipment vibration is reduced, the comfort level and the work performance of operators can be improved, and the health problem risk caused by long-time exposure of workers to high-intensity vibration environments is reduced. Assuming that the loss of working period due to health problems is 80 hours per year and the working cost per hour is 100 yuan, the cost of working period per year can be saved by 8000 yuan. The vibration damper also plays a role in reducing noise, so that the working environment of an operator is improved, noise pollution to the surrounding environment can be avoided, and noise treatment cost is reduced. One study showed that the shock absorber reduced vibration noise by about 10 db.

The automatic hammer crusher is used as an automatic starting and stopping hammer crusher, and the material detector and the conveyor belt are adopted, so that the downtime can be reduced, the production efficiency can be improved, and the risk and the cost of the whole production line can be reduced; by installing the alarm, the fault can be found in time, further damage to equipment is avoided, and the maintenance cost is reduced; through installing the bumper shock absorber, can reduce potential mechanical failure risk, reduce the cost of administering the noise.

The foregoing has shown and described the basic principles and main features of the present utility model and the advantages of the present utility model. It will be understood by those skilled in the art that the present utility model is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present utility model, and various changes and modifications may be made without departing from the spirit and scope of the utility model, which is defined in the appended claims.
