The present invention relates to a belt conveyor cleaner device, and more particularly, by spraying a protective liquid on the belt surface of the belt conveyor to satisfy the lubrication function and the impurities removal function of the belt to the external damage and The present invention relates to a belt conveyor cleaner device that prevents tip cleaner wear and effectively removes residues from a shipment.

In general, the belt conveyor is wound by a pulley (pully) is driven by the power of the drive motor, the transport material carried on the belt has a composition of water and dirt mixed with the belt surface to remove these phenomena Normally, a cleaner was used.

As an example, in order to remove the foreign matter adhering to the belt B as in FIG. 1, the tip cleaner C installed at an inclination of about 10 to 15 degrees to the traveling direction of the belt has been used. In the belt rotating in the forward direction, cleaning was possible, but when it was installed in a reversible belt in which the forward and reverse rotations were repeated, the belt did not have a proper inclination angle. As a result, the foreign matters are not completely removed, and as in FIG. 1 (b), the belt is damaged by multiple reflections.

In addition, there was a risk that the belt would be cut if the cleaner dust occurred deeply on the belt surface.

In some cases, rubber type cleaners in which rubber is assembled to prevent such belt damage are replaced. However, the cleaning effect of the cleaner is insufficient, and foreign substances are transferred to the rollers, resulting in the continuous musk phenomenon of the belt. Suppressing the driving force is not able to properly play the role of the cleaner.

In addition, the cleaning on the forward rotation side can be processed by the lower chute (Chute), but the foreign matter that has not been removed is cleaned on the reverse rotation side as it is stagnant in the lower equipment, causing enormous damage to the interference equipment.

In order to solve the above problems, the cleaning device of the reversible belt conveyor of the Republic of Korea Utility Model Publication No. 1998-45952 proposed in the prior art is driven up and down according to the rotation direction of the belt belt belt cleaner to remove the foreign matter on the belt surface In the reversible cleaning device of the belt conveyor installed on each side, '□' type cleaner (1) in contact with the inner surface of the belt to move forward and backward by the friction force, but the shaft inserted through the guide plate (3) is coupled And a lever 6 coupled to the arm 4 connected to the '□' type cleaner 1, and a rotating shaft 5 driven by the arm 4 and a fixed jaw 9 are formed. And a tip-type cleaner 8 driven up and down along the rail 7 by the operation of the lever 6 is installed on both sides of the belt.

In the cleaning device of the reversible belt conveyor configured as described above, the '□' type cleaner (1) installed on the belt inner surface (B) is pushed back by the rotational and frictional force of the belt as the belt rotates in the forward direction. The arm 4 is moved by the operation of the '□' type cleaner 1 by the axis where the 'type cleaner 1 and the arm 4 are connected.

Therefore, the force by which the arm 4 moves through the rotary shaft 5 is transmitted to the lever 6 so as to pivot the lever 6 about the lever shaft.

That is, by turning the lever 6, the tip cleaner 8 is moved upward along the rail 7 to remove foreign substances adhering to the belt surface in contact with the belt.

However, the cleaning device of the conventional reversible belt conveyor is configured to move the tip cleaner up and down by receiving frictional force with the belt surface of the '□' type cleaner installed at the inner edge of the belt, thereby removing foreign substances on the belt surface. However, the life of the belt is shortened by friction between the belt and the tip-type cleaner, and in the case of a viscous moving object, there is a problem that it cannot be completely removed.

In addition, as shown in the Republic of Korea Patent Publication No. 2002-52894, the conveyor belt cleaning device is installed across the upper end of the support installed on each side of the lower belt of the conveyor belt and the rolling roller is in close contact with the lower portion of the belt; And a wheel connected to the rotary shaft of the rolling roller, a slide reciprocating linearly in the slide guide fixed to the support, a connecting rod having one end hinged to the wheel and the other end connected to the slide, and a semi-circular arc-shaped guide. A driving part formed of a guide having a groove formed on an upper surface thereof and communicating with the guide groove in a horizontal direction and fixed to the slide; A lever holder support shaft having one end rotatably inserted into a support bracket installed on the support, an upper lever holder having one end inserted into the lever holder support shaft and contacting the upper surface of the lower belt, and the lever holder One end is fixed to the lower lever holder, one end of which is inserted into the support shaft and the lower lever which is in contact with the lower surface of the lower belt, and the binding loader in which the other end of the upper lever holder and the lower lever holder are integrated, and the other end of which is And a scraper portion including a lever rod to be inserted and a guide roller inserted into the guide groove and fixed to the lever rod.

In the conveyor belt cleaning device configured as described above, when the lower belt 10 rotates, the rolling roller 64 in close contact with the lower belt 10 rotates, and the rotation is transmitted to the reducer 66 and rotated in the reducer 66. The speed is reduced. As the gear 66 rotates, the wheel 68 also rotates, and as a result, the connecting rod 70 also rotates along the wheel 68.

Then, the slide block 72 having the other end of the connecting rod 68 hinged is reciprocated linearly in the slide guide 74.

By this linear motion, the slide 76 and the guide 80 also make a reciprocating linear motion at the same time.

When the guide 80 moves in a straight line, the lever rod 32 reciprocates in the movement path 82 of the guide 80, whereby the upper lever holder 26 and the lower lever holder 28 simultaneously hold the lever holder. The support shaft 24 is rotated reciprocally.

As a result, the levers 26a and 28a in close contact with the upper and lower surfaces of the lower belt 10 wipe off the foreign matters and the like on the belt 10.

Conventional cleaners tend to be unable to remove the deposit completely, which is caused by the presence of fine grooves on the surface of the rubber belt, which cannot be completely removed by the cleaner. Falling drops occur. Or the cleaner further solidifies the attachment resulting in meandering of the belt.

In the case of washing or high-pressure washing in the water tank there was a problem that the secondary damage to the various equipment damage and fall.

In addition, the attachment of the belt acts as an abrasive between the belt and the cleaner, causing abrasion of the cleaner, and there are many methods to solve this by adjusting the adhesion of the cleaner. However, the wear of the cleaner accelerated and the function was not sufficiently exhibited.

Therefore, the main object of the present invention is to spray the protective liquid on the belt surface of the belt conveyor rotating in the track form to satisfy the lubrication function by the protective liquid, thereby preventing external damage to the belt and wear of the tip cleaner It's about making it happen.

In addition, another object of the present invention is to allow impurities remaining in the belt conveyor to be easily released through a protective liquid made of a silicone-based surfactant to maximize the impurity removal function of the belt conveyor.

In addition, another object of the present invention is to remove the protective liquid and air pressure impurities provided at the pressure set through the fluid pressure valve and the filter of the protective liquid injector by spraying a predetermined amount of the protective liquid on the belt surface of the belt conveyor even coating By making the thickness, it is possible to further prevent external damage of the belt by the package or the tip cleaner.

In addition, another object of the present invention is to install a pressure check valve in the protective fluid nozzle line to prevent the backflow of air when the clogging of the nozzle to prevent the air pressure to flow back to the fluid connection line more smooth injection function Is to make it possible.

The belt conveyor cleaner device of the present invention for achieving this object is a belt conveyor for transporting the goods through the belt rotating in an orbital manner by the driven roller and the driven roller and the return roller disposed in the space between the predetermined intervals. In the apparatus, the tip cleaner is disposed so as to be in close contact with the outer peripheral lower portion of the drive roller, but the rotation angle of the tip cleaner can be adjusted by engaging a rotating shaft fixed to a peripheral object in a coupling hole formed in the tip cleaner. And a cleaner unit for removing the residue of the transport object remaining after free fall, and the pneumatic and protection received from the outside by receiving the protective liquid from the tank filled with the protective liquid disposed between the cleaner unit and the return roller. A beam that coats the protective film on the belt by mixing the hydraulic pressure of the liquid and ejecting it to the belt. Characterized in that configured in the liquid ejection apparatus.

According to the present invention, the protective fluid injector is a tank filled with the protective liquid therein, and the protective liquid filled in the tank can be pumped at a constant pressure through a pump at a pressure set through the fluid pressure valve The depressurized or pressurized fluid and the constant pressure air supplied from the outside are pressurized parts which remove impurities contained through the filter and supply them to the outside, and air which is divided into a pair of air connection lines and fluid connection lines connected to the filter. It is characterized by consisting of a nozzle unit coupled to the nozzle line and the protective fluid nozzle line, respectively, to combine the protective fluid and air from the nozzle mounted in the nozzle line in the center to blow out to the outside.

The belt conveyor 10 has a belt in the orbital manner in the driven roller 11 and the driven roller 13 spaced at a predetermined interval, and the return roller 12 is installed in the lower portion of the belt to move the roller 11 And the return roller 12 is driven by a motor (not shown) to rotate the belt 14 in a caterpillar manner to move the transport object.

The removal unit 110 is disposed on the tip cleaner 111 to be in close contact with the outer peripheral lower portion of the circular roller 11, the rotary shaft fixed to the peripheral object in the coupling hole (111b) formed in the tip cleaner 111 Combining the (111a) to enable the angle of rotation of the tip cleaner 111 to freely drop the transport object to remove the remaining transport object residues.

Here, the tip cleaner 111 has one side in close contact with the belt conveyor 10 to form a sharp end in a triangular shape, but the width of the tip cleaner 111 is made to be the same size as the belt conveyor 10.

In addition, the protective fluid injector 120 is disposed between the removing unit 110 and the return roller 12 to receive the protective fluid from the tank 121 filled with the protective liquid, and to receive the hydraulic pressure from the pneumatic and protective fluid. The mixture is sprayed into the belt 14 to coat the protective film on the belt 14.

The protective liquid injector 120 allows the tank 121 filled with the protective liquid therein and the protective liquid filled in the tank 121 to be pressurized at a constant pressure through the pump 122c, but the fluid pressure The pressure reduced or increased by the pressure set through the valve 122a and the air of a constant pressure supplied from the outside are removed from the impurities contained through the filter 122b, and then the supply unit 122 for supplying to the outside, and the filter The air connection line 123b and the protection liquid connection line 123a connected to the 122b are respectively coupled to the air nozzle line 123d and the protection liquid nozzle line 123e branched in pairs to the nozzles 123d and 123e.

In addition, the nozzle unit 123 is provided with a pressure check valve 123f in the protective fluid nozzle line 123e to prevent backflow of air when the clogging phenomenon of the nozzle 123c occurs, so that the air pressure is connected to the protective fluid connection line ( 123a) to prevent backflow.

Then, the protective liquid is to apply a silicone oil-based surfactant to form a protective film on the surface of the belt (14).

In addition, the tip cleaner is preferably applied to a urethane material, and is not limited to the material.

Referring to the operation of the present invention constituted as follows.

The belt 14 rotates in a caterpillar form by the rotation of the driving roller 11 and the return roller 12 that receive the driving force of the motor, and transfers the transported goods to a predetermined area, and then falls in the direction of the driving roller 11. Let's do it.

At this time, the transport object or the residue of the transport product remaining in the belt 14 through the tip cleaner 111 of the removal unit 110 is removed from the belt 14 through the tip cleaner 111 and then the belt 14.
