Description

Technical Field

[0001] This invention relates to the field of high-pressure water jet crushing equipment technology, and in particular to an integrated high-pressure water jet crushing device. Background Technology

[0002] In scenarios such as building renovation, equipment maintenance, and infrastructure upgrades, it is often necessary to first break up and clean the surface of substrates such as concrete and metal (e.g., to remove aging coatings or damaged concrete layers). Traditional high-pressure water jet crushing equipment uses nozzles to spray high-pressure water jets to break up, remove rust, or remove coatings from the substrate surface. However, when crushing equipment is used to treat high-strength or dense surface substrates, it encounters problems such as difficulty in initial crack initiation and low crushing efficiency, making it difficult to meet the needs of efficient and high-quality renovations.

[0003] In addition, a large amount of debris is generated during the crushing operation. Currently, the debris is cleaned up manually after crushing is completed, which affects the progress of subsequent operations. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated high-pressure water jet crushing device, which at least partially solves one of the technical problems in related technologies.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A high-pressure water jet crushing integrated device includes an integrated working chamber, the bottom of which is set as an opening facing the working surface; The inner side of the integrated working chamber is equipped with a pretreatment component, which includes an impact block. The impact block is installed on a reciprocating motion mechanism. The reciprocating motion mechanism drives the impact block to make reciprocating linear motion in the vertical direction, so that the impact block impacts the working surface to achieve pretreatment. The integrated work chamber has a nozzle assembly on its inner top, which includes a nozzle seat and one or more nozzles mounted on the nozzle seat. The nozzles spray high-pressure water jets onto the work surface.

[0006] Based on the above, there are two types of nozzles: an inclined nozzle and a normal nozzle. The high-pressure water jet from the inclined nozzle is directed at an angle towards the working surface, while the high-pressure water jet from the normal nozzle is directed perpendicularly towards the working surface.

[0007] Based on the above, the reciprocating motion mechanism includes a slide rod extending in the vertical direction and a bushing fixedly connected to the integrated work cabin, wherein the slide rod and the bushing slide in the vertical direction; and an impact block is fixedly installed at the lower end of the slide rod. It also includes a turntable installed above the slide bar, which is rotatably mounted on the inner side panel of the integrated work cabin, and is connected to the drive motor outside the cabin; a connecting shaft is fixedly provided at the eccentric position of the turntable; It also includes an eccentric connecting rod, one end of which is rotatably connected to the connecting shaft, and the other end of which is rotatably connected to the upper end of the slide rod; During operation, the drive motor drives the turntable to rotate, which in turn drives the slide rod to reciprocate linearly along the bushing in the up and down direction via the eccentric connecting rod. The slide rod synchronously drives the impact block to move.

[0008] Based on the above, a pre-crushing cone is fixed to the bottom side of the impact block.

[0009] Based on the above, the outer side of the turntable is equipped with a work box, which is fixedly connected to the integrated work cabin. An opening is provided at the bottom of the work box, and a bushing is fixed at the opening.

[0010] Based on the above, the pretreatment component is located on the left or right side of the integrated work cabin.

[0011] Based on the above, the front side of the integrated working chamber is provided with a suction port, a filter screen is provided at the suction port, and the suction port is connected to a suction pipe outside the chamber.

[0012] Based on the above, it also includes a cleaning component for removing material from the filter screen.

[0013] Based on the above, the cleaning assembly includes a rotating rod, which is located on the front side panel inside the integrated work cabin and is arranged parallel to it. A rotating shaft is provided in the middle of the rotating rod, which is rotatably connected to the front side panel inside the cabin. A scraper is provided at one end of the rotating rod corresponding to the filter screen, and a sliding sleeve is slidably fitted at the other end of the rotating rod. It also includes a connecting rod, one end of which is fixedly connected to the slide rod, and the other end of which is fixedly connected to the sliding sleeve.

[0014] Based on the above, the bottom opening of the integrated work cabin is provided with a flexible skirt around it to seal the gap between the integrated work cabin and the work surface.

[0015] The beneficial effects of this invention are: This invention adds an impact-type pretreatment component and a multi-angle nozzle to work together. First, the impact-type pretreatment mechanism impacts the concrete surface to be crushed by high-pressure water jet at high frequency and high speed to create a large number of micro-cracks, stress concentration points and local crushing zones. Then, the high-pressure water jet is used for crushing through the nozzle, which enhances the crack initiation ability of high-strength and dense matrix, and simultaneously improves the crushing depth and operation efficiency, so as to improve the single crushing efficiency of high-strength concrete and eliminate the need for repeated operations.

[0016] This invention includes two types of nozzles: an inclined nozzle and a normal nozzle. The inclined nozzle first acts on the pre-treated surface, using tangential jet impact to cause the concrete to crack and peel off the surface layer. The normal nozzle then further deepens the crushing of the concrete along the same path, improving the crushing effect.

[0017] This invention also adds a suction component that can extract crushed water and mortar through the suction port and suction pipe, and then send them to the mud treatment component for processing, reducing the difficulty of subsequent operations. Through negative pressure suction and a closed chamber design, this invention achieves the discharge of debris and wastewater, meeting the requirements of green construction.

[0018] The invention also includes a cleaning component to scrape away concrete debris from the filter screen, preventing the screen from becoming clogged. Furthermore, the cleaning component works in conjunction with the pretreatment mechanism, reducing the complexity of the equipment. Attached Figure Description

[0020] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the invention. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] like Figures 1 to 5 As shown, this embodiment provides an integrated high-pressure water jet crushing device, including an integrated working chamber 1. The integrated working chamber 1 serves as a closed space for crushing and spraying operations, preventing the spillage of slag and spraying materials, and housing various functional modules. The integrated working chamber 1 is mounted on the linear moving component of the crushing equipment, which is mounted on the lifting component. The lifting component can drive the integrated working chamber 1 to move up and down, and the linear moving component can drive the integrated working chamber 1 to move along the working direction.

[0023] The bottom of the integrated working chamber 1 is open, facing the working surface. A flexible skirt 10 is provided around the bottom opening of the integrated working chamber 1 to seal the gap between the integrated working chamber 1 and the working surface, preventing air leakage during the suction process from affecting the negative pressure.

[0024] The inner top of the integrated work chamber 1 is equipped with a nozzle assembly, which includes a nozzle seat 2. The nozzle seat is fixed to the top of the integrated work chamber 1. An inclined nozzle 4 and a normal nozzle 3 are installed on the nozzle seat. The high-pressure water jet sprayed by the inclined nozzle 4 is inclined towards the work surface, and the high-pressure water jet sprayed by the normal nozzle 3 is perpendicular to the work surface.

[0025] A pretreatment component 5 is provided on the left or right side of the integrated working chamber 1. The pretreatment component 5 includes an impact block 57, which is installed on a reciprocating motion mechanism. The reciprocating motion mechanism drives the impact block 57 to make reciprocating linear motion in the up and down direction, so that the impact block 57 impacts the working surface to achieve pretreatment, create micro-cracks, and reduce the subsequent crushing resistance.

[0026] In this embodiment, the reciprocating motion mechanism includes a slide rod 56 extending in the vertical direction and a bushing 55 fixedly connected to the integrated work cabin. The slide rod 56 and the bushing 55 slide in the vertical direction. An impact block 57 is fixedly installed at the lower end of the slide rod 56. A turntable 52 is provided above the slide rod 56. The turntable 52 is rotatably installed on the inner side plate of the integrated work cabin 1, and the turntable 52 is connected to the drive motor 59 outside the cabin. A connecting shaft is fixedly provided at the eccentric position of the turntable 52.

[0027] An eccentric connecting rod 53 is provided between the turntable 52 and the slide rod 56. One end of the eccentric connecting rod 53 is rotatably connected to the connecting shaft of the turntable 52, and the other end of the eccentric connecting rod 53 is rotatably connected to the upper end of the slide rod 56.

[0028] To improve the pre-crushing effect, a pre-crushing cone 58 is fixed to the bottom side of the impact block 57.

[0029] In this embodiment, a work box 51 is provided on the outer side of the turntable 52. The work box 51 is fixedly connected to the integrated work chamber 1. An opening is provided at the bottom of the work box 51, and a bushing 55 is fixed at the opening. The work box 51 can provide protection and a mounting reference for the transmission structure of the pretreatment component 5.

[0030] A suction port 6 is provided on the front side of the integrated working chamber 1. A filter screen 7 is provided at the suction port 6. The suction port 6 is connected to a suction pipe 8 outside the chamber. The other end of the suction pipe 8 is connected to the mud treatment component.

[0031] To prevent the filter screen 7 from becoming clogged, this embodiment also includes a cleaning component 9 for removing material from the filter screen.

[0032] The cleaning component 9 includes a rotating rod 91, which is located parallel to the front side panel inside the integrated work cabin 1. The rotating rod 91 has a rotating shaft in the middle, which is rotatably connected to the front side panel inside the cabin. One end of the rotating rod 91 is provided with a scraper 92 at the position corresponding to the filter screen 7, and the other end of the rotating rod 91 is slidably fitted with a sliding sleeve 93.

[0033] The sliding sleeve 93 and the sliding rod 56 are connected by a connecting rod 94. One end of the connecting rod 94 is fixedly connected to the sliding rod 56, and the other end of the connecting rod 94 is fixedly connected to the sliding sleeve 93.

[0034] The working principle of this invention is as follows: (1) During operation, the lifting component moves the protective cover 1 to the flexible skirt 10 near the concrete to be broken, and the linear moving component drives the protective cover 1 to move along the working direction on the concrete surface.

[0035] (2) During the movement, the drive motor 59 drives the turntable 52 to rotate. The turntable 52 drives the slide rod 56 to make high-frequency reciprocating linear motion along the bushing 55 through the eccentric connecting rod 53. The slide rod 56, which makes high-frequency reciprocating linear motion, simultaneously drives the impact block 57 and the pre-crushing cone 58 to move at high frequency and high speed, so as to create a large number of micro-cracks, stress concentration points and local crushing areas on the concrete surface to be crushed by high-pressure water jet. Then the inclined nozzle 4 first acts on the pre-treated surface, and the concrete cracks and peels off the surface layer by tangential jet impact. The normal nozzle 3 then further deepens the crushing of the concrete along the same path.

[0036] (3) The suction pipe 8 is connected to the negative pressure suction assembly. After the inclined nozzle 4 and the normal nozzle 3 crush the concrete, the crushing water and mortar are pumped to the mud treatment assembly through the suction port 6 and the suction pipe 8. The filter screen 7 initially intercepts large-volume concrete blocks to prevent the suction pipe 8 from being blocked. At the same time, the high-frequency reciprocating linear motion of the slide rod 56 drives the connecting rod 94 to move up and down. The rotating rod 91 swings through the sliding sleeve 93, and the scraper 92 scrapes off the material on the filter screen 7 with the swing to prevent the filter screen 7 from being blocked.
