Description

A quantitative feeding device and feeding control method for refractory brick forming

Technical Field

The invention mainly relates to the field of refractory brick forming, and in particular to a quantitative feeding device and a feeding control method for refractory brick forming.

Background Art

Refractory bricks are formed by pressing refractory materials in a forming mold through a pressure machine. Before pressing and forming, it is necessary to drive the silo to fill the forming mold through an extension mechanism. The molding quality of refractory bricks is affected by the pressure of the pressure machine and the amount of filler. The density of refractory materials in different areas will be different during the mixing, transportation and storage process. Especially when forming larger refractory bricks, after the refractory materials are introduced into the forming mold, although the filling volume in the cavity of each forming mold is consistent, the density of the refractory materials may be inconsistent, resulting in a large quality error after the refractory bricks are pressed and formed.

Moreover, in the forming process of refractory bricks, if the size of the refractory bricks is large, it is usually necessary to prepare a deeper forming mold, or to continue to add refractory materials after preliminary preforming of the refractory materials in the forming mold. This leads to a large filling error of the refractory materials, thus affecting the consistency of the final forming size of the refractory bricks.

Summary of the invention

In order to solve the deficiencies of the prior art, the present invention provides a quantitative feeding device and a feeding control method for refractory brick molding, which can more accurately control the quality of refractory materials for refractory brick molding and improve the product consistency of refractory bricks.

In order to achieve the above object, the present invention is implemented through the following technical solutions:

The fixed mold cavity corresponds to the sliding mold cavity one by one, and both sides of the silo are slidably connected to the upper slide rails, an upper driving cylinder is arranged between the support frame and the silo, a lower bearing platform is arranged on the rear side of the top surface of the fixed mold, and an upper bearing platform is arranged on the rear side of the top surface of the sliding mold, the bottom surface of the sliding mold cooperates with the lower bearing platform, and the bottom surface of the silo cooperates with the upper bearing platform. A pressure frame is arranged on the pressure platform, and a plurality of lifting sleeves are linearly arranged on the pressure frame. Sliding rods corresponding to the fixed mold cavities are slidably arranged in the lifting sleeves, and a clamping head is arranged at the bottom of the sliding rod. A clamping cylinder for pushing the sliding rod to reciprocate and lift is arranged on the pressure frame, and each of the clamping heads has the same pressure on the refractory material in the corresponding fixed mold cavity, and the size of the clamping head is smaller than the size of the fixed mold cavity; a pushing mechanism is arranged on the outer rear side of the support frame.

The present invention adopts a structure in which a fixed mold, a sliding mold and a silo cooperate to complete the feeding. The silo is used as a receiving component for refractory materials, the fixed mold is used as a quantitative component for refractory materials, and the sliding mold is used to remove excess refractory materials, thereby ensuring that the volume of refractory materials in the fixed mold is constant. The clamping head controls the clamping pressure to make the density of refractory materials in multiple fixed mold cavities consistent, thereby ensuring the overall quality is constant, making the error of refractory materials smaller, and improving the quality consistency of refractory brick products.

Guide sleeves that are slidably matched with the guide rails are arranged on both sides of the support frame. When the support frame is pushed to the far end by the extension hydraulic cylinder, the support frame is a cantilever structure.

Each of the slide bars is equipped with a clamping cylinder, which is an air cylinder. The pressure of the clamping head applied to the refractory material in each of the fixed mold cavities is made consistent by adjusting the air source pressure.

By adjusting the air source pressure, it can be ensured that the refractory material compression of each fixed mold cavity remains constant each time, thereby ensuring the consistency of the refractory brick molding quality.

A connecting plate is arranged on the top of the plurality of slide bars, a buffer sleeve corresponding to the slide bars one by one is arranged on the connecting plate, a ring platform is arranged on the slide bar, a buffer spring is arranged between the ring platform and the buffer sleeve, and the clamping cylinder has one, and the clamping cylinder is used to drive the connecting plate to rise and fall.

The buffer spring balances the downward pressing distance to a certain extent, thereby ensuring the downward pressing distance of the clamping head when the filling amounts in different fixed cavities are inconsistent, thereby making the pressure on the refractory materials in multiple fixed cavities relatively consistent.

A transition platform is arranged on the front side of the top surface of the sliding mold, and the bottom surface of the silo matches with the transition platform.

The outer wall of the pressing head is provided with a skirt, the skirt is in contact with the inner wall of the fixed mold cavity, and a breathable gap is provided on the skirt.

The air-permeable gap can ensure that when the pressing head presses the refractory material, the air in the refractory material can be discharged smoothly, thereby facilitating the compaction of the refractory material.

The skirt edge is a metal edge, and the air permeable gap is a slit grille evenly arranged on the metal edge.

The skirt is a rubber edge or densely arranged bristles.

A feeding control method for a quantitative feeding device for refractory brick forming comprises the following steps:

The refractory material is injected into the overlapping fixed mold cavity and the sliding mold cavity through the hopper, and then the hopper is moved backward, and the refractory material in the sliding mold cavity and the fixed mold cavity is compacted by pressing down with the clamping head. The pressure on the refractory material in each fixed mold cavity is consistent, and then the sliding mold cavity is moved backward, and the supporting frame is moved forward as a whole to make the fixed mold cavity overlap with the refractory brick forming mold, and the refractory material in the fixed mold cavity is introduced into the refractory brick forming mold.

When the pressing head is pressed down to compact the refractory material, the highest position of the refractory material is located in the sliding mold cavity.

Compared with the prior art, the beneficial effects of the present invention are:

The present invention adds a fixed mold and a sliding mold under the silo, and cooperates with a compacting head to achieve pre-compaction of the refractory material before filling, so that the density of the refractory material in the fixed mold cavity exceeds the maximum density area that may exist in the refractory material during mixing, transportation and storage. By controlling the pressure of each compacting head to be consistent each time, the density of the refractory material in the fixed mold cavity is ensured to be constant, and then the quality of the refractory material in the fixed mold cavity is ensured to be constant, thereby ensuring the quantitative feeding of the refractory material into the forming mold.

The present invention has a simple structure and is easy to operate. The pre-compacting action of the refractory material is carried out synchronously during the forming process of the refractory bricks, and will not affect the forming efficiency of the refractory bricks. The refractory material is pre-compacted in a chamber composed of a sliding mold cavity and a fixed mold cavity, and the sliding mold moves backward after compaction, thereby ensuring that the refractory material in the fixed mold cavity is parallel to the cavity to determine the filling volume of the refractory material. By dual determination of the density and volume of the refractory material, the filling quality of the refractory material is guaranteed to be constant.

When pre-compacting the refractory material, the present invention ensures that the thickness of the compacted refractory material is about four times that of the refractory brick. In this state, the density of the refractory material has exceeded the maximum regional density that may be reached during the configuration, transportation and storage of the refractory material. At the same time, the refractory material will not be too compacted to affect the subsequent introduction of the refractory material into the forming mold.

DETAILED DESCRIPTION

The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art may make various changes or modifications to the present invention, and these equivalent forms also fall within the scope limited by the present application.

As shown in Fig. 1-10, a quantitative feeding device for forming refractory bricks of the present invention comprises a pressing table 8, a support frame 1 and a power mechanism 2. The top of the pressing table 8 is a pressing frame, on which a hydraulic mechanism is installed, and a forming mold 9 is provided on the pressing table 8. The pressing head is pressed into the forming mold 9 by the hydraulic mechanism to complete the pressing and forming of the refractory bricks.

The power mechanism 2 includes a pair of guide rails 21 and an extension hydraulic cylinder 22 arranged on the pressing table 8. Specifically, the pressing table 8 has guide rail frames on both sides, and the guide rails 21 are installed above the guide rail frames. The support frame 1 is slidably connected to the guide rails 21, and the extension hydraulic cylinder 22 is used to push the support frame 1 to slide back and forth along the guide rails 21. Guide sleeves 13 that slide with the guide rails 21 are arranged on both sides of the support frame 1. When the support frame 1 is pushed to the far end by the extension hydraulic cylinder 22, the support frame 1 is a cantilever structure. This structural design prevents the guide rails 21 from extending below the hydraulic mechanism, thereby avoiding interference with the pressing mechanism.

The support frame 1 is used as the installation position of each packing component to provide stable support for the packing component. A fixed mold 3 is installed at the bottom of the support frame 1, and the bottom surface of the fixed mold 3 is in contact with the top surface of the pressing table 8. A plurality of fixed mold cavities 31 are linearly arranged in the fixed mold 3, and the fixed mold cavities 31 correspond to the forming mold 9 one by one. The size of the fixed mold cavity 31 is slightly smaller than the size of the forming mold 9, so as to ensure that the material in the fixed mold cavity 31 is completely introduced into the forming mold 9.

A sliding mold 4 is arranged above the fixed mold 3, and the bottom surface of the sliding mold 4 is in contact with the top surface of the fixed mold 3. A silo 5 is arranged above the sliding mold 4, and the bottom surface of the silo 5 is in contact with the top surface of the sliding mold 4. The silo 5 serves as a uniform receiving component for refractory materials, and guides the refractory materials into the sliding mold 4 and the fixed mold 3 below. A pair of lower slide rails 11 and a pair of upper slide rails 12 are arranged on both sides of the support frame 1, and both sides of the sliding mold 4 are slidably connected to the lower slide rails 11, and a lower driving cylinder 42 is arranged between the support frame 1 and the sliding mold 4. Sliding mold cavities 41 corresponding to the fixed mold cavities 31 are arranged in an array in the sliding mold 4, and the size of the sliding mold cavities 41 is completely consistent with the size of the fixed mold cavities 31. The lower driving cylinder 42 is used to push the sliding mold 4 to move relative to the fixed mold 3, and when the lower driving cylinder 42 is fully extended, the sliding mold cavity 41 completely overlaps with the fixed mold cavity 31. When the lower driving cylinder 42 contracts, the sliding mold cavity 41 no longer overlaps with the fixed mold cavity 31, so that the fixed mold cavity 31 is completely exposed.

Both sides of the silo 5 are slidably connected to the upper slide rails 12, and an upper driving cylinder 51 is arranged between the support frame 1 and the silo 5. The upper driving cylinder 51 is used to push the silo 5 to move relative to the fixed mold 3. When the lower driving cylinder 42 is fully extended and the upper driving cylinder 51 is fully extended, the bottom discharge port of the silo 5 coincides with the sliding mold cavity 41, and the refractory material is introduced into the mold cavity composed of the sliding mold cavity 41 and the fixed mold cavity 31. When the upper driving cylinder 51 is retracted, the silo 5 is out of the range of the fixed mold 3.

Furthermore, in order to ensure that the refractory material in the silo 5 and the sliding mold 4 does not leak too much when they are contracted, a lower bearing platform 32 is provided at the rear side of the top surface of the fixed mold 3, and an upper bearing platform 43 is provided at the rear side of the top surface of the sliding mold 4. The bottom surface of the sliding mold 4 cooperates with the lower bearing platform 32, and when the lower driving cylinder 42 contracts, the bottom of the sliding mold cavity 41 is blocked by the lower bearing platform 32. The bottom surface of the silo 5 cooperates with the upper bearing platform 43, and when the upper driving cylinder 51 contracts, the bottom discharge port of the silo 5 is blocked by the upper bearing platform 43.

A pressure frame 6 is arranged on the pressure platform 8. The pressure frame 6 is a gantry structure, and the support frame 1 is allowed to pass under the pressure frame 6. The lower part of the pressure frame 6 serves as the compaction position of the refractory material in the fixed mold 3. When the support frame 1 moves to the lower part of the pressure frame 6 and pauses, the pressure assembly installed on the pressure frame 6 completes the preliminary compaction of the refractory material in the fixed mold 3. A plurality of lifting sleeves 62 are linearly arranged on the pressure frame 6, and a slide bar 61 corresponding to the fixed mold cavity 31 is slidably arranged in the lifting sleeve 62. A clamping head 63 is arranged at the bottom of the slide bar 61, and the clamping head 63 corresponds to the fixed mold cavity 31. By pressing down the clamping head 63, the refractory material in the chamber composed of the sliding mold cavity 41 and the fixed mold cavity 31 can be compacted. A clamping cylinder 64 is provided on the pressure frame 6 for pushing the slide rod 61 to move up and down. Each clamping head 63 applies consistent pressure to the refractory material in the corresponding fixed mold cavity 31, so that the density of the refractory material in each fixed mold cavity 31 is consistent, thereby ensuring the consistent quality of the refractory material filling and reducing the quality error of the refractory bricks after forming.

Specifically, the size of the pressing head 63 is smaller than the size of the fixed mold cavity 31, so that there is a gap between the pressing head 63 and the fixed mold cavity 31, which is convenient for the discharge of air during the compaction of the refractory material. More specifically, a skirt 69 is provided on the outer wall of the pressing head 63, and the skirt 69 contacts the inner wall of the fixed mold cavity 31, and a permeable gap is provided on the skirt 69. The permeable gap on the skirt 69 satisfies the discharge of air in the refractory material when the refractory material is compacted.

Specifically, the skirt 69 is a metal edge, and the air permeable gap is a slit grid evenly arranged on the metal edge. The metal skirt 69 can ensure the compaction of the refractory material at the edge, but the metal skirt 69 is easy to bring the refractory material away from the fixed mold cavity 31.

In another embodiment, the skirt 69 is a rubber edge or densely arranged bristles. The soft structure of the skirt 69 can reduce the amount of drag-out during the compaction of the refractory material, but the durability of the rubber, bristles and other structures is poor and they are easy to fall off and contaminate the refractory bricks. Therefore, after comprehensive consideration, the metal skirt 69 is selected as the optimal structure, and the setting of the sliding mold 4 can still ensure the consistency of the quality of the refractory material in the fixed mold cavity 31.

A pushing mechanism 7 is arranged at the rear side of the outer portion of the support frame 1. The pushing mechanism 7 is used to push the formed refractory bricks away from the conveying device. Specifically, the pushing mechanism 7 can be an inclined pushing plate or a clamp.

Specifically, in order to ensure that the density of the refractory material in each fixed mold cavity 31 is consistent, each slide rod 61 is equipped with a clamping cylinder 64, which is an air cylinder. The pressure of the clamping head 63 is adjusted to ensure that the refractory material in each fixed mold cavity 31 is subjected to the same pressure. Under the condition of ensuring the consistency of pressure, the density of the refractory material can be ensured to be consistent, and then by controlling the volume, the quality of the refractory material in each fixed mold cavity 31 is almost constant, thereby reducing the error of the molding quality of the refractory bricks and making the product quality consistency of the refractory bricks higher.

In another embodiment, in order to reduce the number of clamping cylinders 64, a connecting plate 65 is provided on the top of multiple slide bars 61, a buffer sleeve 66 corresponding to the slide bars 61 is provided on the connecting plate 65, a ring platform 67 is provided on the slide bar 61, a buffer spring 68 is provided between the ring platform 67 and the buffer sleeve 66, and a limit platform is installed on the top of the slide bar 61, and the diameter of the limit platform is greater than the diameter of the buffer sleeve 66. The clamping cylinder 64 has one, and the clamping cylinder 64 is used to drive the connecting plate 65 to rise and fall. Through the pressing of the connecting plate 65, all the slide bars 61 can be driven to perform synchronous downward pressing action, and when the clamping cylinder 64 lifts the connecting plate 65, the connecting plate 65 drives the limit platform to make all the slide bars 61 rise synchronously. Through the setting of the buffer spring 68, when the clamping cylinder 64 is pressed down, the downward pressing depth in different fixed mold cavities 31 can be balanced, and the density in each fixed mold cavity 31 can be relatively consistent to a certain extent.

This device ensures the quality of refractory filling by compacting the refractory material with pressure to ensure that the density of the refractory material in the fixed mold cavity 31 is consistent. The pressing head 63 is pressed into the cavity composed of the sliding mold cavity 41 and the fixed mold cavity 31 to ensure that the density of the refractory material in each cavity is consistent. Subsequently, the sliding mold 4 is driven backward by the lower driving cylinder 42 to remove the excess refractory material in the sliding mold 4, thereby ensuring that the volume of the refractory material in the fixed mold 3 is consistent. By determining the density and volume, the quality of the refractory material in each fixed mold cavity 31 is guaranteed to be consistent, and ultimately the weight error of the formed refractory bricks is smaller, and the quality consistency of the refractory brick products is higher.

Furthermore, a transition platform 44 is provided on the front side of the top surface of the sliding mold 4, and the bottom surface of the silo 5 cooperates with the transition platform 44. The provision of the transition platform 44 enables the silo 5 to slide back and forth under the drive of the upper driving cylinder 51, and injects the refractory material therein into each sliding mold cavity 41 more evenly through vibration, ensuring that after the silo 5 moves backward, the refractory material is flush with the top surface of the sliding mold cavity 41, and ensuring the compaction effect of the subsequent pressing head 63 on the refractory material.

Specifically, the quantitative feeding device for forming refractory bricks is used to feed the forming refractory bricks, and the feeding control method includes the following steps:

First, the support frame 1 is moved backward by contracting the extension hydraulic cylinder 22, and the refractory material is introduced into the silo 5 by a spiral feeding device or a belt feeding device. Then, the support frame 1 is moved toward the molding die 9 by the initial extension of the extension hydraulic cylinder 22, and stops just below the clamping head 63. During this period, the silo 5 reciprocates to fill the refractory material into the chamber composed of each sliding cavity 41 and the fixed cavity 31. After the support frame 1 is paused, the silo 5 moves backward under the contraction of the upper driving cylinder 51, exposing the upper part of the sliding cavity 41. Then, the clamping cylinder 64 drives multiple slide bars 61 to descend, and the refractory material in the sliding cavity 41 and the fixed cavity 31 is compacted by the clamping head 63, and the pressure on the refractory material in each fixed cavity 31 is consistent. When the clamping head 63 presses down to compact the refractory material, the highest position of the refractory material is located in the sliding cavity 41, thereby ensuring the volume of the refractory material in the fixed cavity 31. Then the sliding mold cavity 41 moves backward to remove the excess refractory material, so that the refractory material in the fixed mold cavity 31 is parallel to its top surface. The extension hydraulic cylinder 22 is extended for a second time to push the support frame 1 forward as a whole, so that the fixed mold cavity 31 overlaps with the refractory brick forming mold 9, and the refractory material in the fixed mold cavity 31 is introduced into the refractory brick forming mold 9.
