Description

A sewage automatic pumping wet concrete recycling and screening machine and its application method

technical field

The invention belongs to the technical field of wet concrete recycling, and in particular relates to a wet concrete recycling and screening machine for automatically pumping sewage and a use method thereof.

Background technique

Concrete refers to the cement concrete that uses cement as the cementitious material, sand and stone as the aggregate; it is mixed with water in a certain proportion, and is obtained by mixing, molding and curing. Concrete is a widely used material in construction.

With the wide application of commercial concrete, cement concrete mixing stations produce a large amount of waste residue and waste water while producing commercial concrete. The main sources of these waste residues and waste water are: cleaning discharges from concrete production such as mixing plants, mixer trucks, pump trucks, etc., and discarded concrete that is redundantly ordered by the project. Because these wastewater and waste residues are strongly alkaline, with a pH value of about 12, and contain a large amount of insoluble matter such as cement and sand, if they are not treated and discharged randomly, it will bring disaster to farmland water conservancy, block municipal facilities, and seriously affect environment.

Because of the country's environmental protection requirements for concrete enterprises and the needs of enterprises themselves, concrete needs to be recycled.

The current concrete recovery sewage treatment system mainly recovers the remaining concrete in the concrete mixing plant, the concrete delivery truck, the concrete pump truck and the residual concrete after cleaning by the mixing machine. At present, the common problems of the wet concrete sand separation sewage recovery system at home and abroad are as follows:

1. At present, the screening machines in the wet concrete recovery system at home and abroad all use the overflow port to overflow the sewage in the screening machine. Sewage concrete is poured into the car wash tank, and then a 3kW to 4.5kW water pump is used to wash the concrete in the car wash tank. After the concrete is rushed into the screening machine, the screening process begins. The brought water source forms a huge flood-like water inflow. This huge flood-like water inflow flows into the screening machine, and immediately overflows like a flood from the sewage overflow outlet outside the screening machine, which makes it difficult to drain the water Separated from the sand, resulting in a large amount of sand in the sewage pool, which is not conducive to the subsequent utilization of sewage.

2. In some screening machines, there is also a water pump for washing the screen at the screen, which increases the equipment investment.

3. The huge amount of water inflow, although it eventually returns to the sewage pool, and can also be recycled by car washing, flushing, etc., but the problem of automatic and clean cleaning of the car wash tank and screen has not been completely solved, and manual cleaning is still required. Grooves and screens.

4. The huge influent overflows out of the screening machine, which will bring a very high content of fine sand into the sewage tank.

5. Because the screen cloth of the sewage overflow port of the existing screening machine is in a fixed position, it is easy to be blocked by sand and building fibers, and the overflow port must be cleaned every day.

6. Some wet concrete screening machine manufacturers do not set screens inside the screening machine, and sand and stone are scraped out of the screening machine by the spiral blades. When the stone material is scraped out of the screening machine by spiral blades, there will be no problem if some sand enters the screening machine when the screening machine is idling. Once the screening machine enters the stone material, it will start to affect the current of the driving motor of the screening machine, because the stone material is easy to The screw blade of the screening machine is stuck, which often causes the stuck problem. In severe cases, the driving motor will be burned. Even if it is not stuck, it will cause large stone material conveying resistance, which will lead to problems such as large starting current of the driving motor and unstable voltage. , large power consumption.

7. The motor of the screening machine is installed at the end of the shaft. The inner tank of the screening machine is generally large in volume. It is very difficult for the drive to be set at the end of the central shaft. The required reduction motor has a large power and consumes more power.

8. The management personnel of the batching plant have great opinions on the power consumption of the international and domestic wet concrete recycling systems, because the gain outweighs the loss, that is, the value of the recovered concrete is far less than the value of the consumed electricity. According to a station manager of a mixing station, if there is no car wash in a day for a concrete recycling sewage treatment system, the equipment must be powered on 24 hours a day, and the whole system must run 24 hours a day. It consumes 1,000 kilowatt-hours of electricity every day. When the work is busy, the car will be washed continuously, which consumes more than 4,000 kilowatt-hours of electricity a day. The value of the sand and gravel washed out by the concrete recycling sewage treatment system is less than a fraction of the value of the electricity consumed.

A method for using a wet concrete recovery and screening machine for automatically pumping sewage, comprising the following steps:

a. Feeding: After adding wet concrete and sewage for washing the wet concrete into the car washing tank, the wet concrete will automatically gather at the bottom of the car washing tank, and the sewage will enter the screening machine. The bottom of the car washing tank is higher than the bottom of the screening machine. After the sewage exceeds the height of 500mm, it is the same as the water level at the bottom of the car wash tank, and the sewage submerges the wet concrete in the car wash tank;

b. Pre-mixing conveying: Wet concrete flexible screw conveying, wet concrete flexible conveying screw blade has a small diameter at the bottom and a large diameter at the top, and the material is transported upwards inclined, the discharge port is lower than the feed port, and the material is naturally transformed into a High in and low out, to convey wet concrete materials;

c. Sewage transportation: The water supply spiral pipe is inclined upward to transport the sewage drawn from the spiral sewage pump. When the screening machine is running, the spiral sewage pump follows the rotation of the water supply spiral pipe, and the sewage naturally enters the spiral sewage pump from the water inlet of the water pump. From the water outlet of the water pump into the inside of the water delivery spiral pipe;

d. Sewage, sand and stone screening: When the screening machine is running, the fine sand filter screen cleaner follows the rotation of the water supply spiral pipe, and the sewage is conveyed along the sewage to the spiral blade, and the fine sand passing through each fine sand filter screen cleaner At the water inlet of the filter screen cleaner, if there is fine sand, it will leak from the fine sand filter outlet of the fine sand filter screen cleaner and leak onto the screen. The sewage that has not been leaked from the fine hourglass material port of the sand filter screen cleaner continues to flow out of the water supply spiral pipe along the sewage conveying spiral blade;

e. Screening of stone and sand: The concrete conveyed by the screw blades of the screening machine falls on the screen of the screening system, passes through the screening screw blades to follow the rotation of the screening machine, and is cleaned by the sewage in the screening machine , the sand falls from the sieve into the shell of the screening machine. After the wet concrete sand, stones, and cement are separated, the screening screw blades continue to transport the stones on the screen, and the sieved sand is scraped by the sand to the screw blades. Continue to convey to the outside of the screening machine; the stones after sifting the wet concrete sand through the screening screw blades are transported to the stone conveying screw blades, and the stone conveying spiral blades can keep the stones at the discharge port of the screening system frame, which is more stable out of stone;

f. Sand material conveying: through the sand material scraping screw blade, the sand material transported to the sand material outlet, through the reverse path sand material scraping screw blade, scrapes the sand material into the designated discharge trough of the screening machine for sand material discharge in the slot.

History of invention: The invention lasted more than one year. The inventor has rich working experience in concrete mixing plants, so he has a clear understanding of the shortcomings of modern concrete recovery systems. The screening system of wet concrete recovery systems at home and abroad All of them use the overflow port to overflow the sewage in the screening machine, which requires a lot of water resources to wash, which will make the separation of sand and sewage incomplete, and the overflow port needs to be manually cleaned, so the inventor thought of inventing an automatic screen filter. Cleaning equipment and complete separation of waste water and wet concrete recycling and screening series of sand and stones.

The invention was originally inspired by screw conveyors. Many aspects are inseparable from the technical meaning of the spiral pipe. In the current screening machine, there is flood-like sewage overflowing from the overflow port, although there is an overflow screen to block it. Floods of sewage wash the sand out of the sifters. want to change this situation. The first thought of the present invention is to use the spiral conveying method to convey the sewage out of the screening machine, which is the sewage water conveying device spiral sewage water conveyer of the present invention. The central point of the helical blade of the spiral sewage water feeder considered by the inventor at first has a shaft, and along with the step-by-step advancement of the present invention, the helical blade is set to have a large bottom surface diameter and a small top surface diameter, and the helical blade has a large diameter. The cutting surface maintains the height of the cutting surface consistent up and down. Then think of the fine sand filter screen cleaner, but the combined use of these two inventions has no way to combine with any screening machine at home and abroad at all. The reason why it cannot be combined is that there is no way to extract the sewage at the lowest position in the sieving machine. At this time, the present invention encountered the first bottleneck, and it took a long time without breaking through, until the steel ring on the bicycle was seen once. With the steel wire, inspiration came suddenly, combined with our ancient water digging technology, the first thing that comes to mind is a semicircular water pump, such as the water digging blade of the water wheel, isn’t it just the lowest water that can be dug in the river? Later along with the continuous advancement of the present invention, it is considered that setting the profile of the present invention should be inclined upwards to transport the results more ideally. According to the technical requirement that the water delivery system device of the present invention is tilted upward, at that time I felt that the semicircular water digger could barely be used, but I was not very satisfied with the semicircular water pump, and I always felt that it was better than the semicircular Shaped water pumps are more suitable for water pumps. At that time, I considered various angles to install the semicircular water pump, that is, it should form a 90-degree right angle with the spiral sewage water feeder, or should it be more appropriate to maintain a 45-degree oblique angle, or should it exceed Install at a right angle of 90 degrees, or design the angle at which the semicircular water pump is installed on the shell of the spiral sewage water feeder with the change of the inclination angle of the spiral sewage water feeder. Among them, many water pumps close to semicircle have been considered, and triangular, square pipes, etc. have been considered. After my continuous advancement of the present invention and further understanding of the spiral aspect, in the case of the inclined upward appearance of the spiral sewage water feeder, I thought of the water pump that is most suitable for digging and extracting the sewage in the screening machine in an inclined upward direction. Just should have only the pipeline that uses helical path, and this is the helical pattern sewage digging type water pump that the present invention extracts sewage in the screening machine. Its spiral-style sewage excavation pump is installed in the case of extracting sewage from the shell of the inclined upward sewage water feeder, and its sewage transmission angle is smoother than that of a semicircular water pump to extract sewage in the screening machine. When the spiral path sewage excavation pump is installed on the spiral sewage water feeder, there is no need to consider what angle should be used for installation. When the spiral sewage digging type water pump is installed on the spiral sewage water feeder shell, Just use the same angle as the spiral sewage water feeder to install. After thinking of the spiral pipe to extract the sewage in the sieving machine, there was no breakthrough in the technology of excavating and extracting sewage, that is, there was no further consideration of whether there is a water digger that can better excavate the sewage in the sieving machine.

The present invention has the sewage conveying spiral blade, the fine sand filter screen cleaning device, and the spiral style sewage digging type water pump, and the inventor has confidence in the whole set of wet concrete recovery system. It is difficult for the sewage conveying spiral blade, fine sand filter screen cleaning device, and spiral sewage excavator of the present invention to be combined and installed in any wet concrete recovery system screening machine at home and abroad at present and play a role. The reason is that the shape of the spiral sewage water feeder of the present invention, its sewage outlet pipe, and the sewage outlet must be at the central point of the screening machine, so the present invention has run into the second bottleneck.

According to the unique basic appearance and characteristics of the spiral sewage water feeder, the fine sand filter screen cleaner, and the spiral sewage excavation style water pump of the present invention, the inventor began to set the screening device.

At the beginning, the present invention only thought of using four parts consisting of the casing bracket of the screening system, the screening screw conveying blade, the screen mesh, and the sand material scraping blade. The prototype of the screening system of the present invention had very huge problems at the beginning. . The main problem is that it appears in the two parts of the sand discharge port and the stone discharge port. A spiral sewage water feeder is installed at the central part of the screening machine of the present invention. Restriction of its shape The sand material outlet and the stone material outlet of the prototype of the screening system of the present invention are all super large, so large that no customer will accept it. Here it is the second bottleneck of the present invention.

Later, the inventor thought of setting a set of anti-path sand material scraping screw blades at the sand material outlet of the prototype of the screening system of the present invention to control the sand material in the designated discharge trough, and the sand material is discharged from the discharge port. . The number of the screw blade for stone conveying in the present invention is (32) the screw blade for stone conveying. The outer diameter of the bottom surface of the screw blade is 1060mm, the inner diameter of the bottom surface is 860mm, the outer diameter of the top surface is 800mm, and the inner diameter of the top surface is 740mm. The thickness of the spiral cutting surface is 5mm to 10mm, the number of spiral turns is 1.1, the spiral length is 1100mm, and the pitch is 1000mm. ) The cutting surface is 30mm to 50mm, the blade thickness is 5mm; 2 pieces of annular array; to control the stone can basically keep the stone at the lowest part of the stone discharge port. Screening system of the present invention just can be used. By this time, the second bottleneck of the present invention has almost been broken through. The inventors have great confidence in the invention.

When the inventor has great confidence, that is, when the inventor encounters a bottleneck for the third time, it is the most difficult time for the inventor to advance the invention. Among them thought to use many ways to do the feeding system of the screening machine of the present invention. Incorporating into the screening system of the present invention, the feed system of no screening machine is suitable for the present invention. The reason why the feeding system of other family's screening system is not suitable to be installed in the screening system of the present invention as the feeding system is because the screw sewage water feeder of the present invention is installed at the central point of the screening machine of the present invention. The problem is mainly in feeding and connecting with the screening machine. I have not found a method suitable for the feeding system of the present invention, but others are using it. The diameter of the bottom surface of the shell of the screening machine set by the inventor is 2200mm, and the diameter of the bottom of the spiral shell of the sewage water delivery of the present invention is set to be 900mm to 1000mm. The diameter of the bottommost position of the screen installation position of the screening system frame is 2000mm, and the outer side of the screening system frame is equipped with sand conveying screw blades, and the inner side of the screening system frame is installed with screening screw blades. The inner diameter of the spiral blade is 1800mm, and the inner diameter of the sieving spiral blade provided by the present invention and the maximum outer diameter of the bottom of the spiral sewage water feeder of the present invention have only a distance of about 400mm, and the distance of 400mm and the distance is set The feed pipe must also have a certain distance so as not to collide with the screening machine system. Its invention is to design the design inclined upwards. Inclined upward design, the inner diameter of the screening helical blade provided in its present invention of the present invention and the bottom outer diameter maximum of the spiral sewage water feeder of the present invention have only about 400mm. The available space for slanting upwards is even smaller. Proportionally speaking, the present invention uses a feed pipe with a diameter of 300mm, which must go deep into the screening machine of the present invention, and also maintain some distances, which cannot be compared with the screening system frame. bump. In the case of non-spiral conveying of the pipeline, the material must be fed at an inclined downward angle. To enter the position of the spacing 400mm of the screening system of the present invention. If the screening machine is tilted downward, the 300mm pipe can go deep without touching the shell, but for the tilted upward screening system, the 400mm spacing can go deep into the feed pipe, and the distance that can be maintained becomes smaller on the contrary. up. This third bottleneck has bothered me for a long time. After a long time, I thought of using a screw for conveying. It is not ideal to use the screw to convey the wet concrete containing stones again. The reason is that ordinary spirals are easy to jam the spiral blades. After a long time later, it was thought of using the small diameter of the lower surface, the large diameter of the top surface, and the conical screw to convey the wet concrete containing stones. The tapered screw feed port is small and the discharge port is large. It should be very easy to transport wet concrete containing stones. Until the inventor thought of using a flexible conveying screw to convey the feed and set a bottom diameter at the bottom of the screening system frame, the diameter of the top is the same as the diameter of the screening system frame, and the feed receiving pipe docked with the screening system frame , feed the inside of the material receiving pipe, and then install the material receiving and conveying screw blade, the inventor has thoroughly passed the third bottleneck of the present invention. Completed the design of the whole system.

(3) Beneficial effects:

1. When washing the car, it can reduce the amount of pumping water to rinse the car wash tank. The materials can be automatically concentrated to the bottom of the car wash tank and sent to the screening machine. The car wash does not need to be flushed by the tank water pump, and the inside and outside of the car wash tank can also be kept clean.

2. Use wet concrete flexible feed screw feed, in the case of the spiral conveying material inclined upward, generally speaking, the screw conveying material is conveyed from low to upward, the wet concrete flexible feeding screw of the present invention has a small bottom diameter and a small top The diameter of the surface is large, and the material is conveyed obliquely upward. The wet concrete of the full pipe becomes half-pipe material after the wet concrete is conveyed to the discharge port of the flexible conveying feeding screw during the transportation of the wet concrete flexible conveying feeding screw blade. , the wet concrete with less than half of the pipe material, the wet concrete is lower than the feed inlet at the screw outlet, and the material is naturally transformed into a high-in and low-out conveying mode to convey wet concrete materials, which can be easily conveyed Wet concrete, the way it is conveyed.

3. The spiral sewage pump is used to extract the sewage in the wet concrete recycling screening machine, which can extract the sewage to the lowest water level in the screening machine, which is suitable for sewage extraction at any water level in the screening machine. The sewage in the wet concrete screening machine uses an overflow port There is no way to control the amount of sewage overflowing out of the overflowing sewage. When the water intake of the screening machine is large, the overflowing sewage from the overflow port is too slow. When there is wet concrete in the screening machine that has not been screened clean, the water inflowing into the screening machine is small Sometimes, there will be not enough sewage to clean the wet concrete. When the screening machine is washing the car, sometimes two or even three tankers pour sewage into the screening machine at the same time. Using the overflow method, the large amount of sewage water will also Flush the sand with a huge content in the sewage out of the screening machine, and use the water pump to extract the sewage in the wet concrete screening machine. The water pump is not allowed to continuously extract the sewage in the screening machine when there is sewage in the screening machine. Indirect The extraction is not ideal. Using overflow and water pumps, neither overflow nor extraction can control the problem that there is enough suitable sewage in the screening machine to clean the wet concrete, and control the problem that the sewage will not overflow out of the screening machine. A spiral sewage pump is used. To extract the sewage from the wet concrete recycling screening machine, it can not only control enough sewage in the screening machine to clean the wet concrete, but also ensure that the sewage in the screening machine will not be too full, the screening machine is inclined upward, and the spiral path of the spiral sewage pump Install 30-60 pieces on the water supply spiral pipe. The sewage water level in the screening machine is high. If the sewage in the screening machine can be excavated, there will be more spiral sewage pumps, which is to quickly extract sewage.
