Description

Single machine crushing production line

The invention relates to the field of mining machinery technology, and more particularly to a single machine crushing production line.

Background technique

At present, due to the increasing cost of explosives and labor in the exploitation of raw materials, in order to reduce the mining cost, the size of the raw materials is getting larger and larger, but the required size of the finished material is getting smaller and smaller, so between the raw materials and the finished materials. The crushing ratio is getting bigger and bigger, and the crushing task is no longer completed by a single machine, but a "broken production line" is needed.

There are two types of prior art crushing lines:

The first type of crushing production line is "multi-machine expansion crushing production line" (as shown in Figure 1, Figure 2, Figure 3). There are "level crushing", "secondary crushing" and "three-stage crushing" production lines, and even more crushing production lines. At present, the three-stage crushing production line is the most common.

Figure 1 shows a typical three-stage crushing line (expanded) in the prior art, consisting of eight independent equipment.

The raw material is fed to the first-stage crusher 222 by the feeder 111 at a constant speed for coarse section crushing, and after being discharged, it is sent to the second-stage crusher 444 through the conveyor 333 for fine-stage crushing, and is finely broken and then sent to the second through the conveyor 555. The tertiary crusher 888 is broken and then fed to the tail screen 666 via conveyor 777.

There are two practical requirements for the crushing line: The above is the first type, that is, the three pieces of crushing, the finer the material is broken, such as the crushing of the mining industry (the purpose of crushing is to grind it after grinding). Powder), can directly break the "powder" to be more happy. The process of this production line is "feeding + rough breaking + breaking + fine breaking + screening".

There is also a second practical requirement, that is, the material is not broken as fine as possible, and there is a certain size. (If the stone in the construction industry is broken, the finished material is basically 2~4 cm). After the second stage is crushed, the material is first sieved. The material that has reached the specification size exits the crushing chamber to avoid over-crushing. The material on the sieve enters the third stage of crushing (the crushing after sieving is also called uniform crushing); (The process of this production line is "feeding + coarse breaking + medium breaking + sifting + all breaking + screening")

Fig. 2 is a schematic view of the above-mentioned three-stage crushing production line (expanded type) containing "sieving" in the prior art, which is composed of ten independent devices.

The raw material is fed into the first-stage crusher 222 by the feeder 111 at a constant speed for coarse section crushing, and after being discharged, it is sent to the second-stage crusher 444 through the conveyor 333 for fine-stage crushing, and after being finely broken, the vibration is sent through the conveyor 555. The sieve 666 is sieved, and the sieve top material (large material) is sent to the third-stage crusher 888 through the conveyor 777, and is uniformly crushed, and then sent to the tail sieve 010 through the conveyor 999.

The above "expanded" crushing production lines have the following problems:

(1) The conveyor must be transported by conveyor between each section of the crushing operation, which increases the input cost and operating power consumption of the conveying equipment.

( 2 ) The floor space is large, because the conveyor has a conveying upper angle (generally <18 °, the angle is over the blank), and the crusher equipment and the base have a certain height, so each conveyor length Up to 20_35m. The entire production line of the crushing line is very large.

(3) The equipment is installed and operated at a distance, which is not convenient for unified management.

The second type of crushing production line is "multi-machine centralized crushing production line".

In order to solve the problem that the above-mentioned crushing production line occupies a large area and the use management is inconvenient, people also design a "multi-machine centralized crushing production line", also called "mobile crushing station" (refer to patent ZL200720072195. 6), which is to integrate equipment together. (Generally concentrated on one or several large carts, removable).

Because "multi-machine centralized crushing production line" needs to solve the close distance between the devices set on the same vehicle The technical difficulty of logistics problems is very high, so the structure is very complicated, the cost is also high, and the economy is poor. So far, except for the use of key projects, it has not been widely used.

In order to overcome the above deficiencies, the applicant previously filed the invention patent "single machine crushing production line" (application number is ZL201110092031. 0, see Figure 4). The invention is unique in its ability to replace "independent equipment" with "functional endogenous", that is, one device replaces the above eight devices (see Figure 3). This is a big-span technological advancement! However, the fly in the ointment is that the functions (equipment) contained in the "single-machine crushing production line" are "starting" and not "final". The so-called beginning, because it has a feeding function, the feeding operation is the source of the crushing production line, is the initial process; the so-called endless, because the final broken material is not sieved, and the broken product must pass After "screening" can be achieved, it is the end process.

Disclosure of invention

The object of the present invention is to overcome the defects of the "single-machine crushing production line" having the function of "starting" and "final", and to provide a single-machine crushing production line with complete functions, small floor space, high centralized management and high production efficiency.

In order to achieve the above object, the present invention is achieved by the following technical solutions: A single machine crushing production line, comprising: a crushing mechanism, a base, a vibrating car body and a gantry, wherein the pedestal is disposed in a set by an elastic supporting mechanism On the shelf; the crushing mechanism, the base and the vibrating body are integrated from top to bottom;

The vibrating car body is directly fixed under the base, and the inlet of the vibrating car body is adapted to the crushing chamber outlet of the crushing mechanism, and a screen mesh is arranged in the vibrating body.

The resilient support mechanism includes a spring assembly vertically supported between the base and the gantry and a spring assembly laterally constrained between the base and the gantry;

The spring assembly includes two spring seats. The spring seat further includes a spring mounting head and a mounting head base. The spring mounting head and the mounting head base are hingedly connected, and a spring is connected between the two spring mounting heads.

The crushing mechanism comprises a crusher and a motor, and the crusher is a jaw crusher, a counter crusher, a hammer Crusher or roller crusher.

A feeding compartment is further disposed on the upper side of the base, and the feeding compartment outlet is adapted to the crushing chamber inlet of the crushing mechanism.

The invention has three main structural features:

1. The frame (crusher), the base and the vibrating body are integrated from top to bottom, that is, the frame and the vibration box are respectively connected above and below the base;

2. The feeding car body is arranged above the crusher;

3. The base is connected to the gantry by an elastic support mechanism;

The innovative idea of the invention is:

(1) Three sets of equipment for feeding, crushing and sieving are important equipments for continuous operation in the crushing production line, and the core components all contain "eccentric shaft". It is envisaged that the three equipments of feeding, crushing and sieving together will be used together with the "eccentric shaft", and the functions of "feeding, crushing and sieving" will be combined in the same equipment, using the same "eccentric shaft".

(ie, by a single machine) Complete the whole process of feeding, crushing, and screening.

(2) Using the side cavity and bottom cavity structure space of the jaw crusher, it is envisaged to set up a multi-stage crushing cavity or a screening function in the crushing. As a result, the work originally implemented by "multiple devices" is changed to "single machine".

The above innovative ideas can be summarized by "functional endogenous". The prior art is a "functional" to create an "independent device"; the invention is designed in the same device, through the innovative design of the structure, to give it a variety of required functions.

The core technology of the invention is to replace the conventional "independent equipment" multi-machine combination design idea with the idea of "functional endogenous" innovative design.

That is to use the "single-machine multi-functional endogenous" crushing production line design to replace the existing technology, the conventional "multi-machine combination expansion type" or "multi-machine combination centralized" crushing production line. Its "functional endogenous" has two major technical measures:

First, the "eccentric shaft" in the crushing equipment and the "exciting shaft" in the feeder and vibrating screen equipment are designed as "coaxial", and the "eccentric shaft" in the same equipment is used, that is, the feeding is completed by a single machine. The whole process of crushing and sieving. Its technical measures are:

The crusher is placed above the base by providing a base. Then: 1. Put the core components of the feeder

The "vibrator" is removed, and the remaining "feeding box" is placed above the crusher (the feed box outlet is connected to the crusher feed port); 2. The core part of the vibrating screen is "vibrator" Also removed, the remaining "vibration box" is placed under the base (the vibrating screen discharge port is connected with the upstream end of the vibrating screen), so that the feeding car body, the crusher and the vibrating car body are integrated into one.

In this way, the "eccentric shaft" of the crusher (whether single or double) is also the "exciting shaft" of the feeder and the vibrating screen. It has the same "feeding", "crushing" and "sieving". The functions required for the job.

The second is to make the crusher a multi-functional design, that is, to achieve multi-stage crushing of the same equipment. Its technical measures are:

1. Double-axis double-crank rocker mechanism crusher (referred to as "double-axis breaking"), the structural feature has a machine-level secondary crushing function; (patent number 201110092031. 0)

2, hammer crusher (referred to as "hammer burst"), the structural feature is to set the crushing cavity at the bottom of the moving jaw, the crushing force is large; (patent number 201110336889. 7)

3. "Double-axis breaking" plus "hammer breaking", combining the above two items, designed into a three-stage breaking function of "rough breaking + medium breaking + fine breaking" and "rough breaking + breaking + screening + all broken" "The sifting function is included.

The invention has a number of technical highlights:

1. One of the highlights, the feeder of the original line at the beginning of the production line and the vibrating screen at the end of the production line are pulled together (one upper and lower structure), and the structure of the present invention is compact; 2, the second highlight, the realization of the diversification of the crusher, such as smashing, roller breaking or counter-breaking, etc. can be the structural combination of the present invention, forming a multi-functional, multi-purpose crushing production line;

3, the third highlight, the realization of the multi-functional development of the crusher, with two-stage, three-stage crushing function and mid-way screening function;

4. The fourth highlight, since all the functions of the present invention are endogenous in the same equipment, the logistics are completed in one go, and the conveyor is eliminated, and all the conveyors between the functions are eliminated;

5. Highlight 5: Significant energy saving. The two functions of feeding and screening in the present invention do not consume electricity, but use the residual energy of the crusher, especially the jaw crusher.

The most notable feature of the invention is "energy saving". It is not energy saving in the conventional sense, it is very special energy saving. It completely eliminates the energy consumption of feeding, conveying and screening, and it is a great energy saving!

Energy saving mechanism analysis of the invention:

On the surface, the present invention appears to combine the three functions of feeding, crushing and sieving, but this is not the case in nature. Because:

1. The so-called feeder, crusher and vibrating screen are combined into one. However, the feeder and vibrating screen remove the core component of the exciter, and only the "car" is not a feeder and a vibrating screen in the sense of equipment;

2. The so-called crushing function is combined with the feeding and sieving functions, but it is not. The "feeding" and "sieving" of the present invention not only does not consume work, but also helps the crusher "vibrate".

The highlight of the technical innovation of the present invention is that it becomes "profit" to "profit". The "eccentric" movement of the eccentric shaft of the crusher, while generating the crushing "stroke" to complete the crushing operation, also produces the "vibration" drawback, and people try their best to overcome this "disadvantage". The invention utilizes the "disadvantages" to complete the feeding and sieving "work", and the disadvantages are beneficial.

From the perspective of mechanics, its "energy saving" mechanism is clearer. There are two vibration sources for the jaw crusher. One is the eccentric rotating inertia force caused by the eccentric shaft; the other is the oscillating inertial force caused by the dynamic swaying.

It is easy to overcome the eccentric rotation inertia force, and the eccentric balance can be used. In reality, the balance block is usually added to the flywheel to balance. The self-balancing eccentric shaft technology invented by the Applicant is a new approach (Patent No.: Application No. 201110092031. 0).

It is difficult to overcome the oscillating inertial force. It should follow the law of conservation of momentum of mechanics. The equilibrium formula is

Mlvl=m2v2 o where ml is the dynamic mass, vl is the dynamic speed; m2 is the rack quality, and v2 is the rack speed. The above formula is deformed to _V 2 = ml _V l/m2. From this formula, it is known that the vibration force (ie, the rocking force) is to make the frame speed v2 small. The measure is nothing more than 1. Make the moving mass l become smaller; 2. Or let the moving speed vl become smaller; 3. Or make the frame mass m2 larger.

If the moving speed vl is small, it means that the crushing work becomes smaller and affects the crushing efficiency; the moving mass ml becomes smaller, and the dynamic need to have sufficient strength, rigidity and quality, can not be too small; only the frame mass m2 Being bigger is the way to be realistic and effective.

The technical measure of the invention is to increase the frame quality m2. On the one hand, increasing the mass m2 of the frame can effectively reduce vibration and reduce vibration (ie, reduce v2); on the other hand, the moving jaw reciprocates, and the frame reciprocates (ie, vibrates), which generates vibration damping. Helps reduce vibration. In the present invention, sieving not only does not consume work, but rather helps to dampen vibration. It is an innovation in energy-saving technology in the field of broken technology to use it as a way to create "profit".

It is an innovation in energy-saving technology in the field of broken technology to use it as a way to create "profit". The design of "single crushing production line" is a new exploration of technological progress in the technical field of crushing production lines! Because of its remarkable energy-saving effect, it is also a major energy-saving technology innovation!

Preferably, the lower side of the feeding compartment is erected on the base by a support rod, and the lower side is erected on the gantry by a combination of a support rod and a spring.

Crushing and feeding are important equipment for connection operation in the crushing line, both of which have an "eccentric axis". The crushing equipment uses the eccentric shaft to generate the crushing stroke to complete the crushing operation; the feeder uses the eccentric shaft to generate the exciting motion to complete the feeding operation. It is envisaged that the feeding equipment will be parasitized to the crusher, and the feeding and screening operation will be completed by the "eccentric shaft" side effect (exciting force) of the crusher.

The invention provides a base for carrying the crusher, supports the base through an elastic support mechanism, and then mounts the feeding car body on the base (the feed car outlet should be carried on the base) The crusher inlet is adapted to the inlet), and the vibrating car body is parasitic under the base (the crusher outlet of the crusher carried on the base should be adapted to the inlet of the vibrating car body), and the feeder and the vibrating screen are integrated. , using the crusher to break the side of the movement (crusher eccentric shaft excitation force) to complete the feeding and screening operations.

Preferably, the lower side of the feeding car body is hinged to the crushing mechanism drive shaft concentrically or eccentrically by a support rod, and the other side is erected on the gantry by a combination of a support rod and a spring.

The invention fully utilizes the actual condition that the feeding machine and the main machine of the crusher are fixedly installed and used synchronously, and the exciter of the feeding machine itself is eliminated, and the independent power device driving is not required, but the additional device is added. A "universal connecting link device - concentric articulated or eccentric articulated" that allows it to be connected to different crushers to complete the feeding operation with the excitation function generated by the main unit (crusher) drive , greatly simplifying the structure of the feeder.

The invention skillfully utilizes the realistic condition that the feeder and the crusher are "depending on fixed installation and synchronous operation", removes the vibration exciter and adds a "connecting link device", and completes by means of the power device of the crusher. Feeding operation. In this way, the feeder becomes very compact, lightweight, easy to use and economical. In comparison, the cost of manufacturing a docking linkage is relatively insignificant relative to the manufacture of an exciter. In summary, the invention greatly saves the investment and operation cost of the crushing production line, and facilitates the use and management of the equipment.

The transmission device includes a front transmission gear, a rear transmission gear and a transmission wheel.

Through the two-axis double-crank rocker mechanism, the "lower force" of the front lower jaw is changed to "enhanced force", and the stroke that is originally in the discharge function (referring to the horizontal movement of the lower part of the front) is changed to have the breaking function. The stroke, and the discharge function is also naturally completed during the crushing process (both the crushing stroke and the discharge stroke). The front crank rocker mechanism mainly solves the crushing work in the upper part of the front moving jaw, and the rear crank rocker mechanism mainly solves the crushing work and the discharge material in the lower part of the front moving jaw. Make a crusher equivalent to a secondary crush ability.

The moving hammer itself is the ideal hammer hammer (because of the large mass); c. The rotary motion of the hammer has completed the lifting movement of the hammer hammer, 2 Integral, save power; d. Because the hammer is broken, it is suitable for large crushing than fine material, and the broken broken cavity is connected with the broken broken cavity.

The mechanism of the invention utilizing the dynamic gravity to participate in the crushing is also one of the important features of the present invention. The gravity mentioned here refers to the gravity of the vertical center of the earth (not the weight of the parts involved in the crushing, the weight of the parts involved in the crushing is very common, such as broken smashing, hammered hammer, counter-breaking hammer and many more) . This feature is unique among all crushers.

(1) Punching principle, the structure of the crusher of the present invention is a crank-link mechanism from the mechanical principle, the crank drive shaft is a crank, the weight is a connecting rod, and the crank is good at a small angular position when the work is broken, using " The small angle enhances the "mechanical principle, which can amplify the crushing force. For example, the punching machine in the machine tool uses the principle of crank "small angle boosting force", so that a block of only a few hundred kilograms can generate hundreds of tons of momentum to complete the punching process.

(2) The principle of the air hammer, the structure of the crusher of the present invention is essentially an air hammer from the principle of dynamics. Due to the large mass of the hammer, when the crank pulls the hammer up to the point, the mass of the hammer The potential energy is obtained. When the crank pulls the hammer down to the point, the potential energy releases a huge kinetic energy, which is several times the mass of the weight. This kinetic energy (plus the weight of the weight itself) is used as the breaking force. It is very advantageous. It can be seen from the above that the two forces, impulse and kinetic energy, already have a large crushing force on their own, and the two together are even larger, so the hammer crusher can be said to be super large in the crusher. The leader of the crushing force.

The bottom crushing chamber uses the mechanism of gravity to participate in the crushing. The gravity here refers to the gravity of the vertical center of the earth (not the weight of the parts is involved in the crushing, and the weight of the parts is very common, such as breaking the hammer and breaking the hammer. Hammerhead, counterattack broken hammer board, etc.). This feature is unique among all crushers.

1. Simplified equipment and reduced manufacturing costs (removal of feeder and vibrating shaker and its power After the matching, the weight of the feeder and vibrating screen is reduced by about 3 (Γ40%, and the cost is reduced by about 5 (Γ60%).

2. Save equipment self-consumption. Feeder and vibrating screen set the exciter device to make the structure huge (large material), its own weight, self-consumption work accounted for about 20%, after removing the exciter, in addition to saving 20%, it also omitted two Input cost and operating power consumption of the conveying equipment.

3. Simplify the process of crushing the production line for easy installation, maintenance and maintenance. About 90% of the failure of the feeder and shaker occurs in the exciter assembly. After the exciter is removed (the rest is mainly the car), there is almost no mechanical failure except for the replacement of the wear parts.

4. It is convenient to transform old products.

5. Small footprint.

6. Function centralized, stand-alone operation, easy to use and manage. DRAWINGS
