Description

Technical Field

[0001] The invention relates to the technical field of hollow brick firing, in particular to equipment for firing hollow bricks sintered from building solid waste. Background Art

[0002] The construction solid waste sintered hollow brick firing equipment is a production line specially used to process construction waste (such as concrete, bricks, mortar, etc.) into hollow bricks. It mainly includes a crushing device, a brick blank forming device and a firing shaping device.

[0003] The crushing device on the existing hollow brick firing equipment is mostly equipped with an impurity filtering component to filter impurities such as thin films and large-volume wood blocks in the crushed construction solid waste. In order to facilitate the thorough and effective unblocking of the filtering component, the filtering component is often arranged in a form that can be directly taken out from the crushing device without disassembly. In addition, some equipment directly performs light unblocking on the filtering component inside the crushing device to extend the frequency of taking out the filtering component for thorough cleaning, and often arranges the filtering component in a form that can vibrate to unblock. However, in the existing equipment, the active removal operation of the filtering component during thorough unblocking and the vibration operation during light unblocking need to be driven and implemented by two different sets of driving mechanisms respectively, which causes the equipment to be equipped with two sets of driving mechanisms for the above two operations respectively, which is not conducive to simplifying the structure of the equipment and reducing the cost. Summary of the invention

[0004] In view of this, the present invention provides a sintering hollow brick firing device for construction solid waste to solve the problem that the movable removal operation implemented when the filter component is completely unblocked and the vibration operation implemented when the blockage is lightly unblocked need to be driven and implemented separately by two different drive mechanisms. This causes the equipment to be equipped with two sets of drive mechanisms for the above two operations respectively, which is not conducive to simplifying the structure of the equipment and reducing the cost.

[0005] The technical solution proposed by the present invention is: a construction solid waste sintered hollow brick firing equipment, specifically comprising: a crushing device, the crushing device as a whole is composed of a crushing drum and a rotating crushing frame rotatably arranged inside the crushing drum;

[0006] An interception filter assembly is installed in the bottom side space inside the crushing cylinder in the form of swing plug-in. The interception filter assembly is located below the rotating crushing frame and is composed of an outer retaining ring and a metal filter covering the inside of the retaining ring. An L-shaped rotating shaft is welded to the outer periphery of the retaining ring. A positioning sleeve is welded to the outer periphery of the crushing device at an adjacent position above the interception filter assembly. The vertical shaft section of the L-shaped rotating shaft rotates and slides with the positioning sleeve in a penetrating manner. The crushing cylinder peripheral wall is provided with a metal filter assembly at the same height as the interception filter assembly. An arc-shaped slot is provided through the position, and the intercepting filter assembly is inserted into the crushing barrel through the arc-shaped slot; a slide groove connected with the arc-shaped slot is provided on the top of the arc-shaped slot near one end of the L-shaped rotating shaft; when the intercepting filter assembly is inserted into the crushing barrel, the retaining ring is completely removed from the arc-shaped slot; when the intercepting filter assembly is inserted into the crushing barrel, the bottom horizontal part of the L-shaped rotating shaft is aligned with the slide groove up and down, and in this state, the bottom horizontal part of the L-shaped rotating shaft slides upward with the L-shaped rotating shaft and cooperates with the slide groove.

[0007] Furthermore, a horizontally supported L-shaped mounting rod is welded to the top of the L-shaped rotating shaft, and a hexagonal plug shaft positioned by spring pushing is slidably installed between the upright part of the L-shaped mounting rod and the top part of the L-shaped rotating shaft;

[0008] A positioning ear block is welded to the top of the positioning sleeve at one side of the L-shaped rotating shaft, and one end of the hexagonal plug shaft protruding from the L-shaped rotating shaft is plugged into and matched with the positioning ear block;

[0009] The half of the hexagonal plug shaft away from the positioning ear block is bent toward the crushing device.

[0010] Furthermore, the outer periphery of the retaining ring is welded with an arc-shaped cover plate spaced apart from the retaining ring, and when the intercepting filter assembly is inserted into the crushing barrel, the arc-shaped cover plate abuts against and blocks the outer peripheral opening of the arc-shaped slot;

[0011] There are multiple connection blocks welded around the arc-shaped cover plate and the retaining ring, and a semi-annular slide groove is formed between the arc-shaped cover plate and the retaining ring. When the arc-shaped cover plate slides upward following the interception filter assembly, the semi-annular slide groove slides with the peripheral wall of the crushing cylinder located at the top of the arc-shaped slot.

[0012] The height of the arc-shaped cover plate is greater than the height of the arc-shaped slot. When the arc-shaped cover plate slides upward along with the interception filter assembly, the portion of the arc-shaped cover plate below the connection block slides to cover the open space between the retaining ring and the bottom side of the arc-shaped slot.

[0013] When the intercepting filter assembly is in a downward sliding state, the connecting block abuts against the bottom side of the arc-shaped slot.

[0014] Furthermore, one end of the arc-shaped cover plate is in abutment contact with the bottom horizontal portion of the L-shaped rotating shaft;

[0015] A vertically supported hexagonal positioning shaft is welded on the outer periphery of the crushing barrel near the L-shaped rotating shaft, and two arc-shaped shielding plates positioned by spring push are symmetrically slidably installed on the hexagonal positioning shaft. The two arc-shaped shielding plates are arranged on the upper and lower sides of the horizontal part of the bottom side of the L-shaped rotating shaft and are both in contact with the horizontal part of the bottom side of the L-shaped rotating shaft.

[0016] The arc-shaped shield plate on the upper side blocks and covers the slide groove, and a rod sleeve is welded to the tail end of the arc-shaped shield plate. A tightening bolt is screwed through the peripheral wall of the rod sleeve, and the head end of the tightening bolt is in contact with the hexagonal positioning shaft.

[0017] Furthermore, a driving device is fixedly provided at the center position of the top opening of the crushing barrel, and the driving device is connected to the rotating crushing frame for transmission through a coupling.

[0018] Furthermore, a ground-contacting support frame is welded to the bottom side portion of the outer periphery of the crushing barrel.

[0019] Furthermore, it also includes a forming device and a first conveyor belt, wherein the first conveyor belt is arranged between the crushing device and the forming device, and one end of the first conveyor belt extends below the discharge port at the bottom of the crushing drum, and the other end extends to the feed port of the forming device.

[0020] Furthermore, it also includes a firing device and a second conveyor belt, wherein the second conveyor belt is arranged between the molding device and the firing device, and one end of the second conveyor belt extends to the discharge port of the molding device, and the other end extends to the feed port of the firing device.

[0021] The construction solid waste sintered hollow brick firing equipment provided by the present invention has the following beneficial effects:

[0022] 1. The intercepting filter assembly is slidably installed through an L-shaped rotating shaft. The intercepting filter assembly can be driven to vibrate at a high frequency directly inside the crushing barrel by simply reciprocating the L-shaped rotating shaft up and down, so as to implement vibration clearing of impurities blocked on the metal filter of the intercepting filter assembly. Compared with the existing technology that directly fixes the intercepting filter assembly inside the crushing barrel and needs to remove the intercepting filter assembly from the inside of the crushing barrel for clearing, this can save the tedious steps of frequently removing the intercepting filter assembly for clearing, and the clearing operation of the intercepting filter assembly is simpler and more efficient.

[0023] 2. The intercepting filter assembly is installed by swinging through an L-shaped shaft. The intercepting filter assembly can be driven to swing out of the crushing barrel by twisting the L-shaped shaft clockwise (refer to the figure), so as to implement thorough and effective unblocking of the intercepting filter assembly. Compared with the existing technology of directly fixing the intercepting filter assembly inside the crushing barrel, this can save the trouble of disassembling the crushing device as a whole to remove the intercepting filter assembly for thorough unblocking. The operation is simple and time-saving, which helps to improve the efficiency of thorough unblocking of the intercepting filter assembly.

[0024] 3. Since the vibration clearing operation of the intercepting filter assembly is relatively simple, the intercepting filter assembly can be frequently vibrated to perform light clearing of the intercepting filter assembly. Relatively frequent light clearing of the intercepting filter assembly can effectively extend the time it is completely blocked, reduce the frequency of swinging it out for thorough clearing, reduce the workload of workers in dealing with complex thorough clearing operations, reduce the occupation of normal production time of equipment by thorough clearing operations, and indirectly improve the production efficiency of equipment.

[0025] Fourth, the swinging and disengaging action performed by the intercepting filter assembly during the thorough clearing operation and the high-frequency vibration action performed during the light clearing operation can both be driven by the L-shaped shaft, which allows the above two operations to be driven by a common L-shaped shaft. Compared with the existing technology, it is unnecessary to configure a driving mechanism similar to the L-shaped shaft for the above two operations respectively, which helps to simplify the overall structure of the crushing device and the firing equipment and reduce its cost.

DETAILED DESCRIPTION

[0041] Please refer to Figures 1 to 10 ;

[0042] Embodiment 1:

[0043] The present invention provides a construction solid waste sintered hollow brick firing device, comprising: a crushing device 1, the crushing device 1 as a whole is composed of a crushing cylinder 101 and a rotating crushing frame 104 rotatably arranged inside the crushing cylinder 101;

[0044] An interception filter assembly 105 is installed in the bottom space inside the crushing barrel 101 in the form of swing plug-in. The interception filter assembly 105 is located below the rotating crushing frame 104, and the whole is composed of an outer retaining ring and a metal filter covering the inside of the retaining ring; an L-shaped rotating shaft 1052 is welded to the outer periphery of the retaining ring; a positioning sleeve 1011 is welded to the outer periphery of the crushing device 1 at an adjacent position above the interception filter assembly 105, and the vertical shaft section of the L-shaped rotating shaft 1052 rotates and slides with the positioning sleeve 1011 in a penetrating manner; an arc-shaped slot 1014 is opened on the peripheral wall of the crushing barrel 101 at a position at the same height as the interception filter assembly 105. , the intercepting filter assembly 105 is inserted into the crushing barrel 101 through the arc-shaped slot 1014; a slide groove 1013 connected to the arc-shaped slot 1014 is opened on the top of the arc-shaped slot 1014 near one end of the L-shaped shaft 1052; when the intercepting filter assembly 105 is inserted into the crushing barrel 101, the retaining ring is completely removed from the arc-shaped slot 1014; when the intercepting filter assembly 105 is inserted into the crushing barrel 101, the bottom horizontal part of the L-shaped shaft 1052 is aligned with the slide groove 1013 up and down, and in this state, the bottom horizontal part of the L-shaped shaft 1052 slides upward with the L-shaped shaft 1052 and slides with the slide groove 1013;

[0045] The interception filter assembly 105 is used to intercept and filter impurities such as thin films and large wood blocks in the construction solid waste fragments formed by the rotating crushing frame 104. Intercepting and filtering impurities can prevent impurities from being mixed with the construction solid waste fragments, which requires additional filtering and sorting later; the interception filter assembly 105 is slidably installed by the L-shaped rotating shaft 1052. Only by reciprocating the L-shaped rotating shaft 1052 up and down can the interception filter assembly 105 be driven to vibrate directly at a high frequency inside the crushing cylinder 101, and the impurities blocked on the metal filter of the interception filter assembly 105 are vibrated and cleared. Compared with directly fixing the interception filter assembly 105 The existing technology that is placed inside the crushing barrel 101 and needs to remove the intercepting filter assembly 105 from the crushing barrel 101 to implement the blockage removal can save the cumbersome steps of frequently removing the intercepting filter assembly 105 to implement the blockage removal, and the blockage removal operation of the intercepting filter assembly 105 is simpler and more efficient; the high-frequency vibration implemented by the intercepting filter assembly 105 can slightly clear the blockage of its body to cope with the working condition where the blockage is not serious; the intercepting filter assembly 105 is installed by swinging through the L-shaped rotating shaft 1052, and only by twisting the L-shaped rotating shaft 1052 clockwise, the intercepting filter assembly 105 can be driven to swing out of the crushing barrel 101 (refer to Figure 4), the interception filter assembly 105 is thoroughly and effectively cleared, which can save the trouble of disassembling the crushing device 1 to remove the interception filter assembly 105 for thorough clearing compared with the prior art of directly fixing the interception filter assembly 105 inside the crushing barrel 101, and is easy to operate and time-saving, which helps to improve the efficiency of thorough clearing of the interception filter assembly 105;

[0046] It is worth noting that: when the interception filter assembly 105 is completely cleared, the interception filter assembly 105 needs to be swung out from the inside of the crushing cylinder 101, and the arc-shaped slot 1014 will be exposed and opened, causing the solid waste blocks of the building to be leaked. Therefore, when the interception filter assembly 105 is completely cleared, the equipment needs to be temporarily shut down;

[0047] Since the vibration clearing operation of the intercepting filter assembly 105 is relatively simple, the intercepting filter assembly 105 can be vibrated frequently to perform light clearing of the intercepting filter assembly 105. Relatively frequent light clearing of the intercepting filter assembly 105 can effectively extend the time it is completely blocked, reduce the frequency of swinging it out to perform thorough clearing, reduce the workload of workers in dealing with complex thorough clearing operations, reduce the occupation of the normal production time of the equipment by the thorough clearing operation, and indirectly improve the production efficiency of the equipment.

[0048] The swinging and disengaging action performed by the intercepting filter assembly 105 during the thorough blockage clearing operation and the high-frequency vibration action performed during the light blockage clearing operation can both be driven by the L-shaped rotating shaft 1052, which allows the above two operations to be driven and implemented by sharing the L-shaped rotating shaft 1052. Compared with the prior art, it is unnecessary to configure a driving mechanism similar to the L-shaped rotating shaft 1052 for the above two operations respectively, which helps to simplify the overall structure of the crushing device 1 and the firing equipment and reduce their cost.

[0049] Based on the first embodiment, the second embodiment:

[0050] Preferably, a horizontally supported L-shaped mounting rod 1053 is welded to the top of the L-shaped rotating shaft 1052, and a hexagonal plug shaft 1054 positioned by spring pushing is slidably installed between the vertical part of the L-shaped mounting rod 1053 and the top part of the L-shaped rotating shaft 1052; a positioning ear block 1012 is welded to the top of the positioning sleeve 1011 at one side of the L-shaped rotating shaft 1052, and one end of the hexagonal plug shaft 1054 protrudes from the L-shaped rotating shaft 1052 and is plugged into the positioning ear block 1012; the half of the hexagonal plug shaft 1054 away from the positioning ear block 1012 is bent toward the crushing device 1;

[0051] When the protruding portion of the head end of the hexagonal plug shaft 1054 is plugged into the positioning ear block 1012, the intercepting filter assembly 105 can be positioned in a state of sliding down and inserted into the crushing barrel 101, and the L-shaped rotating shaft 1052 can be twisted and driven to slide up and down through the hexagonal plug shaft 1054.

[0052] Preferably, the outer periphery of the retaining ring is welded with an arc-shaped cover plate 1051 spaced apart from the retaining ring. When the intercepting filter assembly 105 is inserted into the crushing cylinder 101, the arc-shaped cover plate 1051 abuts against and blocks the outer periphery opening of the arc-shaped slot 1014. When the intercepting filter assembly 105 is in a downwardly sliding stationary state, the arc-shaped cover plate 1051 completely blocks the outer periphery opening of the arc-shaped slot 1014, thereby preventing the construction solid waste fragments in the crushing cylinder 101 from jumping out through the outer periphery opening of the arc-shaped slot.

[0053] There are multiple connection blocks 1055 welded around the arc cover plate 1051 and the retaining ring. A semi-annular slide groove is formed between the arc cover plate 1051 and the retaining ring. When the arc cover plate 1051 slides upward following the interception filter assembly 105, the semi-annular slide groove slides with the peripheral wall of the crushing cylinder 101 at the top of the arc slot 1014.

[0054] The height of the arc cover plate 1051 is greater than the height of the arc slot 1014. During the high-frequency vibration clearing process, when the arc cover plate 1051 slides upward following the intercepting filter assembly 105, the part of the arc cover plate 1051 below the connecting block 1055 slides to cover the open space between the retaining ring and the bottom side of the arc slot 1014, thereby preventing the fragments of solid construction waste inside the crushing barrel 101 from jumping out through the open space above; when the intercepting filter assembly 105 is in a sliding state, the connecting block 1055 is in contact with the bottom side of the arc slot 1014.

[0055] Preferably, one end of the arc-shaped cover plate 1051 is in contact with the bottom horizontal part of the L-shaped rotating shaft 1052; a vertically supported hexagonal positioning shaft 1015 is welded near the outer periphery of the crushing barrel 101 and the L-shaped rotating shaft 1052, and two arc-shaped shielding plates 1016 positioned by spring pushing are symmetrically slidably installed on the hexagonal positioning shaft 1015, and the two arc-shaped shielding plates 1016 are arranged on the upper and lower sides of the bottom horizontal part of the L-shaped rotating shaft 1052 and are in contact with the bottom horizontal part of the L-shaped rotating shaft 1052; the upper arc-shaped shielding plate 1016 blocks and covers the slide groove 1013, and a rod sleeve is welded at the tail end of the arc-shaped shielding plate 1016, and a tightening bolt 1017 is screwed through the peripheral wall of the rod sleeve, and the head end of the tightening bolt 1017 is in contact with the hexagonal positioning shaft 1015;

[0056] When the interception filter assembly 105 is in a downward sliding and stationary state, the upper arc-shaped shield plate 1016 is completely blocked on the slide groove 1013, which can prevent the construction solid waste fragments inside the crushing cylinder 101 from jumping out through the slide groove 1013; through the upward sliding pushing effect of the interception filter assembly 105 and the rebound pushing effect of the upper spring on the hexagonal positioning shaft 1015, when the interception filter assembly 105 is performing high-frequency vibration clearing, the bottom horizontal part of the L-shaped rotating shaft 1052 can be used to push and drive the upper arc-shaped shield plate 1016 to slide up and down synchronously. In this process, the upper arc-shaped shield plate 1016 can be in real time in contact with the upper side edge of the slide groove 1013 and the protection The slots between the holding rings are constantly changing in size, and the slots that are constantly changing in size are adapted to be blocked; through the downward push effect of the interception filter assembly 105 and the rebound push effect of the upper and lower springs of the hexagonal positioning shaft 1015, the interception filter assembly 105 can be pushed by the bottom horizontal part of the L-shaped rotating shaft 1052 to drive the lower arc shield 1016 to slide up and down when performing high-frequency vibration clearing. In this process, the lower arc shield 1016 can be attached to the vacant slot that is constantly changing in size formed between the bottom horizontal part of the L-shaped rotating shaft 1052 and the bottom opening of the slide slot 1013 in real time, and the vacant slot that is constantly changing in size is adapted to be blocked;

[0057] The two arc-shaped shield plates 1016 are used together with the arc-shaped cover plate 1051, and when the intercepting filter assembly 105 is subjected to high-frequency vibration clearing, the sliding groove 1013 and the arc-shaped slot 1014 of constantly changing size are blocked, so as to prevent the building solid waste fragments inside the crushing cylinder 101 from jumping out through the two grooves and affecting the normal use of the crushing device 1. This makes it possible for the high-frequency vibration clearing operation to not interfere with the normal use of the crushing device 1, so that the intercepting filter assembly 105 can be operated to perform high-frequency vibration clearing without shutting down the crushing device 1, which can avoid the high-frequency vibration clearing operation from occupying the normal production time of the crushing device 1, and is helpful to indirectly improve the production and use efficiency of the crushing device 1 and the firing equipment as a whole;

[0058] It is worth noting that: when the two arc-shaped shields 1016 are respectively kept in the upward sliding and downward sliding states, space can be left for the horizontal part of the bottom side of the L-shaped rotating shaft 1052 to swing and move. When the intercepting filter assembly 105 is swung out for thorough clearing, the two arc-shaped shields 1016 need to be kept in the above state, and the two tightening bolts 1017 can respectively keep the two arc-shaped shields 1016 in the above state.

[0059] Preferably, a driving device 103 is fixedly provided at the center position of the top opening of the crushing barrel 101, and the driving device 103 is connected to the rotating crushing frame 104 for transmission via a coupling.

[0060] Preferably, a ground contact support frame 102 is welded to the bottom side of the outer periphery of the crushing barrel 101 .

[0061] Preferably, it also includes a forming device 2 and a first conveyor belt 4, the first conveyor belt 4 is arranged between the crushing device 1 and the forming device 2, and one end of the first conveyor belt 4 extends to below the bottom discharge port of the crushing drum 101, and the other end extends to the feed port of the forming device 2.

[0062] Preferably, it also includes a firing device 3 and a second conveyor belt 5, the second conveyor belt 5 is arranged between the molding device 2 and the firing device 3, and one end of the second conveyor belt 5 extends to the discharge port of the molding device 2, and the other end extends to the feed port of the firing device 3.

[0063] It is worth noting that: the forming device 2 is a conventional forming device on the market that can manufacture the blank into a hollow brick wet blank, the firing device 3 is specifically a conventional kiln on the market, and the first conveyor belt 4 and the second conveyor belt 5 are both conventional conveyor belts on the market. Therefore, the above equipment belongs to the prior art, and its structure, function and working principle will not be elaborated here.

[0064] The working principle of this embodiment is as follows: when in use, the construction solid waste is added into the crushing barrel 101 through the top opening of the crushing barrel 101. After entering the crushing barrel 101, the construction solid waste is crushed into small particles by the high-speed rotating crushing frame 104. The small particles are discharged downward through the metal filter screen inside the interception filter screen assembly 105, and discharged through the bottom opening of the crushing barrel 101. The volume impurities mixed in the small particles, such as wood blocks and films, are retained at the top of the metal filter screen. The impurities filtered and retained at the top of the metal filter screen are removed from the crushing barrel 101 by swinging the interception filter screen assembly 105 to be cleaned and discharged. The height of the arc-shaped slot 1014 is greater than the height of the interception filter screen assembly 105, which can ensure that the trapped impurities can smoothly pass through it and normally escape from the inside of the crushing barrel 101.

[0065] The fragments of solid construction waste discharged from the bottom opening of the crushing drum 101 are conveyed to the forming device 2 by the first conveyor belt 4, and are manufactured and formed into hollow brick wet blanks inside the forming device 2. After the hollow brick wet blanks are manufactured and formed, they are conveyed to the firing device 3 by the second conveyor belt 5 for high-temperature firing and shaping, and finally form hollow brick finished products.
