Description

Technical Field

[0001] The invention belongs to the technical field of concrete residual material separation, and in particular relates to a concrete pump pipe residual material separation and collection device. Background Art

[0002] Concrete pump pipes are pipe systems used to transport concrete, usually made of special wear-resistant and pressure-resistant materials such as high-strength steel or special polymers. They are mainly used in concrete pouring projects to transport concrete from the mixer truck to the specific pouring location, such as the floor, wall or column of the construction site.

[0003] In the Chinese patent with publication number CN117358569B, the first-level filter cover, the second-level screening bucket and the second-level filter cover are used to scrape the filtered residual materials on each of them during the rotation process, so that the residual materials are turned over, so as to facilitate the filtering of the residual materials, and avoid the problem that the residual materials are not fully filtered and cause blockage; and when discharging, the first-level filter cover, the second-level screening bucket and the second-level filter cover are used to block the residual materials on each of them during the rotation process, and the residual materials are blocked at the corresponding discharge port 1 and discharge port 2, so that the separated residual materials can be discharged completely, and the separated residual materials are prevented from accumulating in the separation cylinder and affecting the next operation of the separation cylinder, achieving the effect of one machine with two uses;

[0004] However, the above device has the following problems during use: first, the gravel in the concrete residue is left on the secondary screening bucket, and the outer surface of the secondary screening bucket is inclined from the middle to both sides. During the filtering process, the gravel will slide down to the bottom area of ​​the secondary screening bucket under the action of its own gravity. During the rotation of the secondary screening bucket, there is not enough thrust between it and the scattered gravel, so the speed of pushing the gravel to the lever area is slow, resulting in a slow discharge speed of the gravel, and the discharge of the gravel is more time-consuming;

[0005] Secondly, the gravel accumulates in the bottom area of ​​the secondary screening bucket, and part of the gravel at the bottom will be stuck in the filter holes in the secondary screening bucket. When these gravel collides with the gear lever, the gravel stuck in the filter holes will damage the filter holes, causing damage to the filter holes, resulting in the need for frequent replacement of the screening components used to intercept the gravel. Summary of the invention

[0006] The object of the present invention is to provide a concrete pump pipe residual material separation and collection device to solve the problems of time-consuming stone collection, easy damage and high replacement frequency of the screening parts intercepting the stones proposed in the above background technology.

The lower end surface of the cross plate fits the upper surface of the filter plate. Grooves are provided on both sides of the cross plate. A protective sleeve that is engaged with the grooves is installed on the upper side of the cross plate. An arc-shaped portion is provided on the upper side of the protective sleeve. A protective cap is threadedly connected to the upper side of the drive seat.

[0012] Preferably, an L-shaped blocking ring is fixedly mounted on the outer plate of the filter assembly, the protective sleeve abuts against the inner wall of the inner circle of the blocking ring, and the upper end surface of the cross plate inserted into the inner part of the blocking ring abuts against the outer wall of the blocking ring.

[0013] Preferably, the material discharge component includes at least two working states, wherein the two working states are a horizontal filtering state and an inclined material discharge state, respectively. The material discharge component includes a material discharge plate, one end of which is rotatably installed in the sewage trough through a rotating shaft, and a guide groove is arranged in the material discharge plate, and a plurality of through holes penetrate the material discharge plate, and an arc-shaped embedded groove is arranged at the bottom of the through hole.

[0014] Preferably, when the blanking assembly is in an inclined blanking state, the lower end surface of the blanking plate abuts against the inner wall of the track groove in the solid discharge track, and the solid discharge track penetrates the outer wall of the separation shell.

[0015] Preferably, an inclined plate is rotatably installed at one end of the unloading plate away from the rotating shaft, and the other end of the inclined plate is rotatably connected to a hook plate, and the hook plate is fixedly connected to a lifting block, and the lifting block is slidably connected to a lifting track fixedly installed on the inner wall of the separation shell, and the lifting block is connected to a lead screw through a thread, and the lead screw is connected to a power motor for driving it to rotate forward and reverse.

[0016] Preferably, the gravel filter hole protection mechanism includes two main protection plates, which are respectively located on both sides of the intermediate shaft, and the two main protection plates are connected to a retractable and retractable assembly for driving the two-way rotation thereof.

[0017] Preferably, the retractable assembly is connected to a cylinder for driving it to move up and down, the main protective rod is fixedly mounted on the main protective plate, and the main protective rods on the two main protective plates correspond one to one with the filter holes of the filter plate in the gravel filter.

[0018] Preferably, a blanking plate guard plate is provided at a position on one of the main guard plates corresponding to the blanking assembly, and a plurality of slave guard rods corresponding to the through holes are fixedly mounted on the upper side of the blanking plate guard plate, and a hemispherical portion is provided on the top of the slave guard rod, and the blanking plate guard plate is inserted into a parallel groove in the parallel frame, and the parallel groove is parallel to the blanking plate in the blanking assembly in the inclined blanking state, and a calibration spring is installed between the inner wall of the parallel frame and the blanking plate guard plate.

[0019] Compared with the prior art, the beneficial effects of the present invention are: 1. The filter plate in the filter assembly of the present invention is arranged horizontally, and the stones intercepted by the filter plate in the stone filter will not accumulate in a certain area. When the filter plate cleaning assembly drives the stones to rotate, it always keeps in contact with the filter plate and can obtain the vertical support force provided by the filter plate. Therefore, the filter plate cleaning assembly pushes the stones more smoothly.

[0020] 2. The material discharge component of the present invention has two working states: a horizontal filtering state and an inclined material discharge state. When discharging, the material discharge plate therein tilts downward, and the stones pushed by the filter plate cleaning component fall into the guide groove in the material discharge plate under the action of gravity, and then are discharged along the solid discharge track. There is no obstruction in the process of stone discharge, and the stone discharging speed is faster.

[0021] 3. The present invention sets a gravel filter hole protection mechanism on the lower side of the gravel filter. When it is in the protection state, the main protection rod inside it is inserted into the filter hole in the gravel filter to push out the gravel in the filter hole. When the gravel is pushed by the filter plate cleaning component, it will not collide with the filter hole, and the filter hole that intercepts the gravel is not easily damaged.

[0022] 4. The internal gravel filter of the present invention is also provided with a feed plate protection plate and a secondary protection rod at the feed plate. When the main protection rod is inserted into the filter hole, the through hole in the feed plate is blocked, which can prevent the through hole from hindering the sliding of the gravel and eliminate the obstruction of the gravel sliding in the feed plate.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Reference Figure 1-Figure 4 A device for separating and collecting excess concrete from a concrete pump pipe comprises a separation shell 1, a concrete pump pipe 2, and a filter assembly 3. The concrete pump pipe 2 is connected to the separation shell 1 to feed excess concrete into the separation shell 1. The two can be connected by plugging or by assembling. Figure 1 As shown, the filter assembly 3 is connected by bolts. It should be noted that the filter assembly 3 is installed inside the concrete pump pipe 2, and at least two filter assemblies 3 are provided, and the two filter assemblies 3 are respectively a gravel filter 301 and a sand filter 302. It should be noted that the gravel filter 301 is closer to the concrete pump pipe 2 than the sand filter 302. The gravel filter 301 is used to intercept gravel in the concrete residue, and the sand filter 302 is used to intercept sand in the concrete residue after the gravel is screened out. The remaining water in the concrete residue flows out from the bottom of the separation shell 1 after passing through the sand filter 302;

[0040] Specifically, the filter assembly 3 includes a filter plate in the middle with a square shape, and an outer plate with a circular outer shape and an inner square hole. The filter plate is inserted into the square hole in the outer plate. The filter holes of the filter plates in the gravel filter 301 and the sand filter 302 are different in size. The filter holes in the gravel filter 301 are larger, and a single filter hole can allow multiple sands to pass through at the same time, but the above-mentioned filter holes do not allow gravel to pass through, so the gravel is left on the upper side of the filter plate. The two filter assemblies 3 are arranged in sequence from top to bottom to separate gravel and sand in the concrete residue.

[0041] In a further embodiment, Figure 5 , 6As shown, a filter plate cleaning component 4 is installed on the filter component 3. The filter plate cleaning component 4 on the gravel filter 301 is used to push the intercepted gravel into the corresponding unloading component 5. The filter plate cleaning component 4 connected to the sand filter 302 is used to push the intercepted sand into the unloading component 5 connected thereto; the filter plate cleaning component 4 can rotate around the center point of the filter plate in the filter component 3, gather the gravel or sand accumulated on the upper surface of the filter plate, and push it into the unloading component 5. When used together with the unloading component 5, the material on the upper surface of the filter component 3 can be pushed away, completing the cleaning of the upper surface of the filter plate;

[0042] Specifically, the filter plate cleaning assembly 4 includes a drive seat 401 and a drive mechanism. The drive mechanism is connected to the intermediate shaft in a transmission manner. The intermediate shaft is detachably connected to the drive seat 401. A transverse plate 402 is fixedly installed on the drive seat 401. The lower end surface of the transverse plate 402 is in contact with the upper surface of the filter plate. Grooves 403 are provided on both sides of the transverse plate 402. A protective sleeve 404 engaged with the groove 403 is installed on the upper side of the transverse plate 402. An arc portion is provided on the upper side of the protective sleeve 404. A protective cap 405 is connected to the upper side of the drive seat 401 through a thread. The protective sleeve 404 is located at the protective cap 405. On the upper side, it should be noted that the protective sleeve 404 is made of rubber material, and the top of the protective sleeve 404 and the protective cap 405 are both set to an arc shape, so that the concrete residue falls from the top to the bottom and can flow to the lower side along the arc structure of the outer surface thereof, and during the rotation of the horizontal plate 402, its rotational force can separate the concrete residue with less adhesion on the top from it, so as to avoid excessive accumulation of concrete residue on the upper end surface of the filter plate cleaning assembly 4, so that a large amount of concrete residue will not remain on the upper end surface of the filter plate cleaning assembly 4, and it is more labor-saving when the driving mechanism drives it to rotate;

[0043] It should be noted that the filter plate is set to be square in shape, and the horizontal plate 402 rotates around the center point of the filter plate during rotation. The area cleaned is larger than the area of ​​the filter plate. The outer plate to which the filter plate is plugged is the area where the horizontal plate 402 rotates. During the rotation of the horizontal plate 402, its rotational force will cause part of the concrete residue to be thrown away. In order to avoid this situation, Figure 5 As shown, an L-shaped blocking ring is fixedly installed on the outer plate of the filter assembly 3, the protective sleeve 404 is against the inner wall of the inner ring of the blocking ring, and the upper end surface of the part of the horizontal plate 402 inserted into the blocking ring is against the outer wall of the blocking ring; the blocking ring is used to limit the horizontal plate 402 to prevent the concrete residue from being thrown away, and similarly, the rotation of the horizontal plate 402 can be limited to play a guiding and buffering role, so as to prevent it from shaking violently due to collision with stones during the rotation process;

[0044] In a further embodiment, Figure 5 , Figure 7 , Figure 8As shown, the material discharge assembly 5 is installed in the sewage trough in the filter assembly 3, and the material discharge assembly 5 includes at least two working states, wherein the two working states are respectively a horizontal filtering state and an inclined material discharge state; in the horizontal filtering state, the material discharge plate 501 in the material discharge assembly 5 is parallel to the filter plate to intercept stones or sand, and in the inclined material discharge state, the material discharge plate 501 in the material discharge assembly 5 is inclined downward to discharge stones or sand pushed by the filter plate cleaning assembly 4 from the filter plate;

[0045] Specifically, the material discharge assembly 5 includes a material discharge plate 501, one end of which is rotatably installed in the sewage trough through a rotating shaft, and a guide groove 502 is arranged in the material discharge plate 501, and the guide groove 502 can play a role of diversion. When the material discharge assembly 5 is in an inclined material discharge state, gravel or sand moves along the guide groove 502, which can prevent gravel or sand from falling from both sides. A plurality of through holes 503 are penetrated in the material discharge plate 501, and the through holes 503 have the same size as the filter holes at the corresponding filter plates. When the material discharge assembly 5 is in a horizontal filtering state, the through holes 503 and the filter holes filter the concrete residue together, and an arc-shaped embedded groove is arranged at the bottom of the through hole 503, and the arc-shaped embedded groove is arranged to be gradually expanded from top to bottom, so as to facilitate the insertion of the protection rod 606 in the subsequent gravel filter hole protection mechanism 6;

[0046] More specifically, when the material discharging assembly 5 is in an inclined material discharging state, the lower end surface of the material discharging plate 501 abuts against the inner wall of the track groove in the solid material discharging track 504, and the solid material discharging track 504 penetrates the outer wall of the separation shell 1. In order to realize the transition of the two states of the material discharging assembly 5, an inclined plate 505 is rotatably installed at one end of the material discharging plate 501 away from the rotating shaft, and the other end of the inclined plate 505 is rotatably connected to the hook plate 506, and the hook plate 506 is fixedly connected to the lifting block 507, and the lifting block 507 is slidably connected to the lifting track 508 fixedly installed on the inner wall of the separation shell 1, and the lifting block 507 is connected to the lead screw through a thread, and the lead screw is connected to the power motor used to drive it to rotate forward and reverse;

[0047] In a further embodiment, if Figure 9-12As shown, in order to allow the sand to pass quickly through the filter plate in the gravel filter 301, the aperture of the filter hole in the filter plate needs to be larger than the size of multiple grains of sand, that is, a single filter hole can allow multiple grains of sand to pass through at the same time, and some gravel in the concrete residue will be stuck in the filter hole. When cleaning the filter plate, the filter plate cleaning component 4 directly pushes the gravel on the filter plate. During the pushing process, the gravel stuck in the filter hole will violently collide with the inner wall of the filter hole (the volume of sand is small and relatively smooth, and the damage to the filter hole caused by it when being pushed by the filter plate cleaning component 4 is small). , therefore, the problem of damage to the filter holes in the sand filter 302 is not considered), which will cause the filter holes to be enlarged. After long-term use, the filter holes will not be able to intercept stones. In order to protect the filter holes in the filter plate, a stone filter hole protection mechanism 6 is set in the separation shell 1. The stone filter hole protection mechanism 6 has at least two states including a protection state and a contraction state. When the stone filter hole protection mechanism 6 is in the protection state, the main protection rod 604 therein is inserted into the filter hole in the filter plate of the stone filter 301, and the stone stuck in the filter hole can be pushed out;

[0048] In this way, when the filter plate cleaning assembly 4 cleans the stones intercepted on the upper surface of the filter plate, the stones will not directly rub against the inner wall of the filter hole, thereby better protecting the filter hole. When the stone filter hole protection mechanism 6 is in a contracted state, all the components therein are not located below the filter hole in the stone filter 301, thereby preventing the concrete residue from being blocked by the stone filter hole protection mechanism 6.

[0049] Specifically, the stone filter hole protection mechanism 6 includes two main protection plates 601, which are respectively located on both sides of the intermediate shaft. The two main protection plates 601 are connected to a retractable assembly 602 for driving the two-way rotation thereof. When the stone filter hole protection mechanism 6 is turned into a retracted state, the retractable assembly 602 is required to rotate the main protection plates 601 to a vertical downward direction so as not to hinder the filter hole from filtering stones normally. The retractable assembly 602 is connected to a cylinder 603 for driving the up and down movement thereof. The main protection rod 604 is fixedly mounted on the main protection plates 601. The main protection rods 604 on the two main protection plates 601 correspond one by one to the filter holes of the filter plate in the stone filter 301.

[0050] More specifically, a blanking plate guard plate 605 is provided at a position corresponding to the blanking assembly 5 on one of the main guard plates 601, and a plurality of slave guard rods 606 corresponding to the through holes 503 are fixedly installed on the upper side of the blanking plate guard plate 605, and a hemispherical portion is provided on the top of the slave guard rod 606. The blanking plate guard plate 605 is inserted into a parallel groove in the parallel frame 607, and the parallel groove is parallel to the blanking plate 501 in the blanking assembly 5 in the inclined blanking state, that is, the blanking plate guard plate 605 can only move up and down in a direction parallel to the blanking plate 501, and a calibration spring 608 is installed between the inner wall of the parallel frame 607 and the blanking plate guard plate 605;

[0051] When the material discharging assembly 5 is in an inclined material discharging state, the filter plate cleaning assembly 4 needs to be used to clean the intercepted stones. In order to prevent the stones from damaging the filter holes, the stone filter hole protection mechanism 6 needs to be lifted to a height at which the main protection rod 604 is inserted into the filter hole, so that the stones can be pushed by the filter plate cleaning assembly 4, fall into the inclined guide groove 502, and be discharged along the solid discharge track 504. In order to prevent the stones from getting stuck in the through holes 503 in the material discharging plate 501, a material discharging plate protection plate 605 is set on one of the main protection plates 601, and the main protection rod 604 moves in a vertically upward direction, while the main protection rod 604 moves in a vertically upward direction. The protection rod 606 needs to be moved in alignment with the through hole 503, and the movement directions of the two are not exactly the same. In order to allow the two to be respectively plugged into the corresponding channels, a parallel frame 607 parallel to the blanking plate 501 is set at the blanking plate protection plate 605. The blanking plate protection plate 605 and the secondary protection rod 606 can move up and down in a direction parallel to the blanking plate 501, and a hemispherical portion is set on the top of the secondary protection rod 606, and an arc-shaped embedded groove is set at the bottom of the through hole 503. The two guide each other, so that the secondary protection rod 606 can be inserted into the corresponding through hole 503, so that the stones can be unloaded without being blocked by the through hole 503.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
