Description

Technical Field

[0001] The utility model relates to the technical field of concrete pouring equipment, in particular to a drag reducing, washing and draining recovery device for high-rise concrete pump pipes. Background Art

[0002] At present, high-rise buildings are mostly poured with a truck-mounted pump + floor concrete distributor + pump pipe. After the concrete is poured, concrete remains in the pump pipe, and the pump pipe and concrete distributor need to be cleaned in time. In the cleaning operation of the existing technology, most of the cleaned waste is directly discharged, or driven into a hopper, and then lifted away by a tower crane.

[0003] Since there are many recyclable aggregates in the waste, the direct scattering method is relatively wasteful and easy to pollute the environment. The method of pumping into the hopper is not convenient for the recovery of aggregates, which increases the workload and leads to low cleaning efficiency of high-rise concrete pump pipes. At the same time, due to the high height of the pump pipe, the impact force of the waste after cleaning is large, which is easy to cause splashing, is not conducive to civilized construction, and also has certain safety hazards. Therefore, it is necessary to provide a drag reduction, washing and recovery device for high-rise concrete pump pipes, which can solve the problems of low cleaning efficiency of high-rise concrete pump pipes, large downward impact force of waste materials, and inability to recover aggregates in the prior art. Summary of the invention

[0004] The utility model aims to provide a drag-reducing, washing and recovery device for high-rise concrete pump pipes, which can solve the problems of low cleaning efficiency of high-rise concrete pump pipes, large downward impact force of waste materials and inability to recover aggregates in the prior art.

[0007] The area of ​​the drag reducing balancing screen is smaller than the radial cross-sectional area of ​​the connecting pipe, so that the drag reducing balancing screen divides the connecting pipe into a screening channel and a non-screening channel, and the non-screening channel at the upper layer of drag reducing balancing screen is located directly above the screening channel at the lower layer of drag reducing balancing screen.

[0008] The screening channel and the non-screening channel equally divide the radial cross section of the connecting pipe.

[0012] The bottom edge of the sub-screening barrel is formed with a convex portion, and the top edge of the sub-screening barrel and the top edge of the bottom barrel are both formed with concave portions, and the convex portion can be matched and inserted into the concave portion, so that two adjacent sub-screening barrels are stacked vertically.

[0022] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] Please see attached Figure 1 To Attachment Figure 4 A drag reduction, washing and recovery device for a high-rise concrete pump pipe comprises a connecting pipe 1, a drag reduction balance screen 2 and a graded recovery bucket; the connecting pipe 1 is connected to the bottom of the high-rise concrete pump pipe and is vertically arranged just above the graded recovery bucket, a plurality of drag reduction balance screens 2 are arranged in the connecting pipe 1 along the axial direction of the connecting pipe 1, and the setting directions of two adjacent drag reduction balance screens 2 are opposite to each other, forming a bidirectional balance screen structure; a drainage hole 301 is formed at the bottom of the graded recovery bucket.

[0024] The high-rise concrete pump pipe can be cleaned by conventional cleaning methods. After cleaning, the waste enters the connecting pipe 1, and multi-stage bidirectional screening is achieved through the bidirectional balanced screen structure to filter out most of the aggregates in the waste, and at the same time, the impact force of the waste flowing downward can be greatly reduced. The number, mesh density and arrangement spacing of the drag-reducing balance screen 2 and the length of the connecting pipe 1 can be adaptively adjusted according to the actual screening requirements to ensure the step-by-step screening and sufficient filtration of the aggregates. The mesh size of each drag-reducing balance screen 2 can be the same or gradually reduced from top to bottom.

[0025] Please see attached Figure 2 The area of ​​the drag reducing balancing screen 2 is smaller than the radial cross-sectional area of ​​the connecting pipe 1, so that the drag reducing balancing screen 2 separates the connecting pipe 1 into a screening channel and a non-screening channel, and the non-screening channel at the upper layer of the drag reducing balancing screen 2 is located directly above the screening channel at the lower layer of the drag reducing balancing screen 2.

[0026] The screening channel ensures the screening and filtering of aggregates in the waste, and the non-screening channel ensures the downward flow of the waste, reduces the flow resistance of the waste, ensures the smooth flow of the connecting pipe 1, and avoids clogging caused by excessive accumulation of aggregates on the upper part of the connecting pipe 1.

[0027] At the same time, due to the provision of the non-screening channel, it is convenient to pour out the screened aggregate in the connecting pipe 1 for recycling at a later stage.

[0028] Please see attached Figure 2 , the screening channel and the non-screening channel equally divide the radial cross section of the connecting pipe 1. Preferably, the drag reduction balance screen 2 is a semicircular screen structure, and the radial cross section of the connecting pipe 1 is a circular structure, that is, the cross sections of the screening channel and the non-screening channel are both semicircular structures.

[0029] The size and shape of the drag-reducing balancing screen 2 can be adaptively adjusted according to actual screening requirements. The drag-reducing balancing screen 2 occupies half of the radial cross-section of the connecting pipe 1, so that the screening channel and the non-screening channel are staggered in the connecting pipe 1, taking into account both the screening effect and the drag-reducing circulation effect.

[0030] Please see attached Figure 2 The drag-reducing balancing screen 2 is provided with a balancing weight rod 201, and the balancing weight rod 201 is arranged in the non-screening channel.

[0031] The balancing weight rod 201 can be used to balance the force on the drag-reducing balancing screen 2 to prevent the aggregate from frequently colliding with the drag-reducing balancing screen 2 and causing deformation and damage to the drag-reducing balancing screen 2 .

[0032] Please see attached Figure 2 The balancing weight rod 201 is arranged along the radial direction of the connecting tube 1, and the length of the balancing weight rod 201 is smaller than the radius of the connecting tube 1.

[0033] The balancing weight rod 201 extends from the cross-sectional center of the connecting tube 1 to the inner wall near the connecting tube 1, which can have a certain deceleration effect on the aggregates in the waste passing through the non-screening channel, which is beneficial to the non-screening channel formed by the next layer of balancing weight rods 201 to effectively screen the aggregates in the waste.

[0034] Please see attached Figure 3 and attached Figure 4 The grading recovery barrel includes a sieve barrel 302, a bottom barrel 303 and a support column 304; a plurality of sieve barrels 302 are vertically stacked on the bottom barrel 303, and the bottom of the sieve barrel 302 is a screen structure, so that two adjacent sieve barrels 302 are connected through the screen; the drainage hole 301 is located at the bottom of the bottom barrel 303, and a plurality of support columns 304 are respectively arranged at the bottom of the bottom barrel 303 and around the drainage hole 301.

[0035] Preferably, the number of screening barrels 302 and the mesh density of the screen structure at the bottom can be adaptively adjusted according to actual screening needs. Due to the multi-stage filtration of the balancing weight rod 201, the aggregate particle size and quantity in the wastewater falling into the screening barrel 302 are relatively small, and the screening barrel 302 with a smaller mesh size can be selected. The mesh size of the screening barrel 302 gradually decreases from top to bottom to ensure the screening effect.

[0036] After the screening is completed, the final wastewater flows into the bottom bucket 303 and is discharged through the drain hole 301. The support column 304 can play a supporting role and at the same time raise the bottom bucket 303 to facilitate the setting and drainage of the drain hole 301.

[0037] Please see attached Figure 3A convex portion 305 is formed at the bottom edge of the sub-screening barrel 302, and a concave portion (not shown in the figure) is formed at the top edge of the sub-screening barrel 302 and the top edge of the bottom barrel 303. The convex portion 305 can be matched and inserted into the concave portion, so that two adjacent levels of sub-screening barrels 302 are vertically stacked.

[0038] The cross-section of the protrusion 305 and the recess can be a rectangular structure, and the protrusion 305 and the recess can be arranged at intervals or circumferentially to facilitate the vertical stacking stability of two adjacent screening barrels 302 and the last screening barrel 302 and the bottom barrel 303, so as to prevent them from tipping over.

[0039] Please see attached Figure 3 and attached Figure 4 A handle 306 is provided on the outer wall of the screening barrel 302 to facilitate the disassembly and assembly of the screening barrel 302.

[0040] Please see attached Figure 1 To Attachment Figure 4 , the usage method and working principle of the utility model are:

[0041] Connect the connecting tube 1 to the bottom of the pump tube and clean the pump tube. The pump tube is cleaned in a conventional manner, which will not be described in detail here.

[0042] After the waste material washed by the pump pipe flows into the connecting pipe 1, it is filtered in multiple stages through the screening channel formed by the drag-reducing balance screen 2. At the same time, the drag is reduced through the non-screening channel to ensure the downward flow of the waste material and reduce the impact force. The aggregate after multi-stage filtration remains on the drag-reducing balance screen 2, and the filtered wastewater enters the graded recovery barrel below.

[0043] The wastewater is subjected to secondary multi-stage screening through the multi-stage screening barrel 302 to improve the screening effect and the cleanliness of the wastewater. The wastewater from the secondary multi-stage screening is discharged to a designated location or recycled through the drain hole 301.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
