Description

Technical Field

[0001] An energy-saving cement pipe manufacturing device involved in this invention, particularly an energy-saving cement pipe manufacturing device applied to the field of cement pipe manufacturing. Background Art

[0002] The essence of cement pipe manufacturing is to process concrete raw materials (such as cement, aggregate, water, etc.) into pipes with specific shapes through physical forming processes. Its core steps include raw material mixing, mold forming, densification treatment, and curing and shaping. Different processes achieve uniform distribution and structural strengthening of concrete through mechanical actions (such as centrifugal force, roller pressure, extrusion);

[0003] The forming mechanism of centrifugal pipe manufacturing is as follows: The mold rotates at high speed (usually driven by a motor), and the concrete in the pipe mold is thrown towards the inner wall of the mold under the action of centrifugal force, forming a uniform pipe wall structure. Combined with roller pressing and vibration assistance, the concrete is further compacted to improve density and compressive strength. The technical characteristics are: wide applicable pipe diameter range (inner diameter 200–1200mm), capable of producing various joint forms such as plain ends and socket ends, short production cycle, suitable for large projects such as municipal drainage and highways.

[0004] When the existing cement pipe manufacturing device takes out the cement pipe, the powdery materials on the outer end and inner wall of the cement pipe will fall off from the cement pipe and spill around the device, thus causing waste of materials. It is not only less energy-saving but also makes the device and its surrounding area rather messy and dirty, which is not convenient for personnel to use when manufacturing cement pipes. Summary of the Invention

[0005] Aiming at the above-mentioned prior art, the technical problem to be solved by this invention is that when taking out the cement pipe, the powdery materials on the outer end and inner wall of the cement pipe will fall off from the cement pipe and spill around the device, thus causing waste of materials.

[0006] To solve the above problems, the present invention provides an energy-saving cement pipe manufacturing device, including a base. An installation groove is opened at the upper end of the base. A first motor is fixedly connected inside the installation groove. A mold cylinder is fixedly connected to the output end of the first motor. An electric push rod is fixedly connected to the inner bottom wall of the mold cylinder. A material taking block is fixedly connected to the telescopic end of the electric push rod. A pair of moving blocks are hinged to the outer end of the mold cylinder. A fitting ring is fixedly connected to the upper end of the moving block. A sponge ring is fixedly connected to the inner wall of the fitting ring. A first lifting plate and a second lifting plate are placed in a fitting manner on the upper end of the base. Collection grooves are opened at the upper ends of the first lifting plate and the second lifting plate. An adjustment groove is opened at the upper end of the first lifting plate. An adjustment plate is rotatably connected inside the adjustment groove through a rotating shaft. A sealing cover is fixedly connected to the upper end of the adjustment plate. A second motor is fixedly connected to the end of the sealing cover far from the mold cylinder. A plurality of fan blades are fixedly connected to the output end of the second motor. A pair of installation pipes are threadedly connected inside the first lifting plate. A pair of threaded holes threadedly connected to the installation pipes are opened at one end of the second lifting plate close to the first lifting plate.

[0007] In the above-mentioned energy-saving cement pipe manufacturing device, it can not only improve the convenience of taking out the cement pipe and scrape the inner wall of the mold cylinder to improve its inner wall cleanliness, but also reduce the amount of material waste and is relatively energy-saving.

[0008] As a further improvement of the present application, grooves adapted to the mold cylinder are opened at one end of the first lifting plate and the second lifting plate close to each other. A rubber base is fixedly connected to the lower end of the base.

[0009] As a further improvement of the present application, the output end of the second motor penetrates the sealing cover and is rotatably inserted inside the sealing cover. A disassembly and assembly block is fixedly connected to the end of the installation pipe far from the first lifting plate. A T-shaped groove is opened at the upper end of the adjustment plate. A T-shaped block slidably connected to the T-shaped groove is fixedly connected to the outer end of the sealing cover.

[0010] As a further improvement of the present application, a plurality of reinforcing frames are fixedly connected to the lower ends of the first lifting plate and the second lifting plate. A suction cup is fixedly connected to the lower end of the reinforcing frame. The lower end of the suction cup is flush with the lower end of the rubber base.

[0011] As a further improvement of the present application, the outer diameter of the material taking block is equal to the inner diameter of the mold cylinder, and the outer end of the material taking block is in contact with the inner wall of the mold cylinder.

[0012] As a further improvement of the present application, a magnetic coating one is applied to the side end of the fitting ring, and a magnetic coating two magnetically connected to the magnetic coating one is applied to the upper end of the mold cylinder.

[0013] As a further improvement of the present application, a plurality of arc-shaped grooves are opened on the inner wall of the groove. A plurality of arc-shaped rubbers are fixedly connected inside the arc-shaped grooves. The side end of the arc-shaped rubber is flush with the inner wall of the groove.

[0014] As another improvement of the present application, a watering can is fixed to one end of the sealing cover away from the mold cylinder. A spray head is fixedly connected to the side end of the watering can. The end of the spray head away from the watering can does not contact the fan blade. Filter holes are formed in the inner bottom wall of the collection tank. Storage grooves are formed at the mutually remote ends of the first lifting plate and the second lifting plate.

[0016] 1. After processing the cement pipe, by moving the material taking block upward, the cement pipe can be pushed out of the mold cylinder, thereby improving the convenience of taking out the cement pipe and scraping the inner wall of the mold cylinder to improve its inner wall cleanliness. During the process of taking out the cement pipe, a pair of sponge rings are used to wipe the adhered and loose materials on the outer end of the cement pipe so that the cement pipe is separated from the materials. Then, the first lifting plate and the second lifting plate are installed on the mold cylinder as a material receiving mechanism. At the same time, the sealing cover is sleeved on the mold cylinder to prevent the materials from spreading in the air when collecting the materials.

To improve the speed at which the materials gather into the collection tank, the operator can start the water pump to spray the water in the watering can to wet the materials. Then, the materials will be mixed with the water mist and quickly fall into the collection tank, thereby reducing the speed at which the materials fall into the collection tank and improving the processing efficiency. Then, the mixture of the materials and water is filtered through the filter holes, and the water passes through the filter holes and drops into the water box.

[0028] The following will make a detailed description of the two embodiments of the present application with reference to the accompanying drawings.

[0029] First embodiment:

[0030] Figures 1-7 An energy-saving cement pipe making device is shown, including a base 1. An installation groove is opened at the upper end of the base 1. A first motor 2 is fixedly connected inside the installation groove. A mould cylinder 3 is fixedly connected to the output end of the first motor 2. An electric push rod 4 is fixedly connected to the inner bottom wall of the mould cylinder 3. A material taking block 5 is fixedly connected to the telescopic end of the electric push rod 4. A pair of moving blocks 6 are hinged to the outer end of the mould cylinder 3. A fitting ring 7 is fixedly connected to the upper end of the moving block 6. A sponge ring 8 is fixedly connected to the inner wall of the fitting ring 7;

[0031] A first lifting plate 9 and a second lifting plate 10 are placed in a fitting manner on the upper end of the base 1. Collection grooves 11 are opened at the upper ends of the first lifting plate 9 and the second lifting plate 10. An adjustment groove 12 is opened at the upper end of the first lifting plate 9. An adjustment plate 13 is rotatably connected inside the adjustment groove 12 through a rotating shaft. One end of the adjustment plate 13 close to the rotating shaft is a conical surface structure so that the adjustment plate 13 can rotate in the adjustment groove 12. A sealing cover 14 is fixedly connected to the upper end of the adjustment plate 13;

[0032] One end of the sealing cover 14 away from the die cylinder 3 is fixedly connected with a second motor 15. A plurality of fan blades 16 are fixedly connected to the output end of the second motor 15. A pair of mounting pipes 17 are threadedly connected inside the first lifting plate 9. A pair of threaded holes threadedly connected with the mounting pipes 17 are provided at one end of the second lifting plate 10 close to the first lifting plate 9;

[0033] Grooves adapted to the die cylinder 3 are provided at one end of the first lifting plate 9 and the second lifting plate 10 close to each other. A rubber base is fixedly connected to the lower end of the base 1. When the first motor 2 rotates to generate vibration, the rubber base can improve the stability of the base 1 on the ground or platform. The output end of the second motor 15 penetrates the sealing cover 14 and is rotatably inserted inside the sealing cover 14. A disassembly and assembly block is fixedly connected to one end of the mounting pipe 17 away from the first lifting plate 9. A T-shaped groove is provided at the upper end of the adjusting plate 13. A T-shaped block slidably connected with the T-shaped groove is fixedly connected to the outer end of the sealing cover 14. After the sealing cover 14 and the adjusting plate 13 are turned up by ninety degrees, when the sealing cover 14 is moved downward, the T-shaped block will move in the T-shaped groove. The T-shaped block and the T-shaped groove can prevent the sealing cover 14 from separating from the adjusting plate 13 and limit the height of the sealing cover 14, so that there is a gap between the fan blades 16 and the sponge ring 8 and the fitting ring 7;

[0034] A plurality of reinforcing frames are fixedly connected to the lower ends of the first lifting plate 9 and the second lifting plate 10. A suction cup is fixedly connected to the lower end of the reinforcing frame. The lower end of the suction cup is flush with the lower end of the rubber base. The outer diameter of the material taking block 5 is equal to the inner diameter of the die cylinder 3, and the outer end of the material taking block 5 is in contact with the inner wall of the die cylinder 3;

[0035] A first magnetic coating 18 is provided on the side end of the fitting ring 7. A second magnetic coating 19 magnetically connected to the first magnetic coating 18 is provided on the upper end of the die cylinder 3. A plurality of arc-shaped grooves are provided on the inner wall of the groove. A plurality of arc-shaped rubbers 20 are fixedly connected inside the arc-shaped grooves. The side end of the arc-shaped rubber 20 is flush with the inner wall of the groove. After the first lifting plate 9 and the second lifting plate 10 are sleeved on the die cylinder 3, the arc-shaped rubber 20 will abut against the die cylinder 3, and the friction force between the two will increase, thereby improving the stability of the first lifting plate 9 and the second lifting plate 10 on the die cylinder 3.

[0036] When this application is used, it is divided into the following steps:

[0037] Step 1: When in use, place the material for producing the cement pipe in the die cylinder 3, and then use an external sealing device to seal the upper end of the die cylinder 3 to prevent the material from being thrown out of the die cylinder 3 during processing;

[0038] Then start the first motor 2, and its output end drives the die cylinder 3 to rotate rapidly. Under the action of centrifugal force, the material is thrown towards the inner wall of the die cylinder 3, so that it is formed and adheres to the inner wall of the die cylinder 3;

[0039] Step 2: When removing the formed cement pipe, the sealing device at the upper end of the mold cylinder 3 needs to be removed from it. Then, turn up the moving block 6, the fitting ring 7, and the sponge ring 8 so that the side end of the fitting ring 7 contacts the upper end of the mold cylinder 3 (as shown in combination with Figure 4 ). At this time, the first magnetic coating 18 will be adsorbed to the second magnetic coating 19, and thus when the moving block 6, the fitting ring 7, and the sponge ring 8 are subjected to an external force, they are not easily moved. After aligning the side ends of the pair of sponge rings 8, the two will form a ring, and the inner diameter of the formed ring is slightly smaller than the inner diameter of the mold cylinder 3;

[0040] Start the electric push rod 4 so that its telescopic end pushes the material taking block 5 upward. When the material taking block 5 moves upward, it will push the cement pipe upward, and thus the cement pipe is pushed out of the mold cylinder 3, greatly improving the convenience when personnel remove the formed cement pipe;

[0041] Step 3: Align the first lifting plate 9 and the second lifting plate 10, sleeved on the mold cylinder 3, and move them upward on the mold cylinder 3 to adjust the distances between the first lifting plate 9 and the second lifting plate 10 and the upper end of the mold cylinder 3. Then, install the installation pipe 17 in the first lifting plate 9 and the second lifting plate 10 to fixedly combine the first lifting plate 9 and the second lifting plate 10 on the mold cylinder 3;

[0042] While the cement pipe moves upward, its outer end will squeeze the pair of sponge rings 8, generating friction with the inner wall of the sponge ring 8. Use the sponge ring 8 to wipe off the materials adhered to the outer end of the cement pipe and the loose materials. Most of the wiped-off materials will fall on the sponge ring 8, the fitting ring 7, and the mold cylinder 3, and a small part will fall into the collection groove 11 on the first lifting plate 9 and the second lifting plate 10;

[0043] After completely moving the cement pipe out of the mold cylinder 3, continue to make the electric push rod 4 push the material taking block 5 upward until the upper end of the material taking block 5 is flush with the upper end of the sponge ring 8. Using the material taking block 5 can not only push the cement pipe out of the mold cylinder 3, but also scrape the inner wall of the mold cylinder 3, improve the cleanliness inside the mold cylinder 3, and push the scraped materials out of the mold cylinder 3;

[0044] Step 4: Turn up the adjusting plate 13 upward so that it drives the sealing cover 14 to rotate upward by ninety degrees together. At this time, the sealing cover 14 will be located directly above the mold cylinder 3. Then, move the sealing cover 14 downward and sleeve it on the mold cylinder 3 (as shown in combination with Figure 7 ). At the same time, the lower end of the mold cylinder 3 will be inserted into the collection groove 11, and its outer end is in close contact with the inner wall of the collection groove 11;

[0045] Start the second starting motor 15, and drive the fan blade 16 at its output end to blow downward, so as to blow away the materials accumulated on all the mechanisms of the material taking block 5 and the die cylinder 3, so that the materials quickly fall into the collection tank 11. Finally, remove the first lifting plate 9 and the second lifting plate 10 from the die cylinder 3, and take out the materials collected therein for use.

[0046] In summary, after processing the cement pipe, by moving the material taking block 5 upward, the present invention can push the cement pipe out of the die cylinder 3, thereby improving the convenience of taking out the cement pipe and scraping the inner wall of the die cylinder 3 to improve the cleanliness of its inner wall. During the process of taking out the cement pipe, a pair of sponge rings 8 are used to wipe the adhered and loose materials at the outer end of the cement pipe, so that the cement pipe is separated from the materials. Then, the first lifting plate 9 and the second lifting plate 10 are installed on the die cylinder 3 as a material receiving mechanism. At the same time, the sealing cover 14 is sleeved on the die cylinder 3 to prevent the materials from spreading in the air during the collection of materials. Finally, the materials are blown into the collection tank 11, and then the materials are taken out from the collection tank 11 for use, thereby reducing the amount of material waste and being more energy-saving.

[0047] The second embodiment:

[0048] On the basis of the first embodiment, the following structure is newly added, and the rest is the same as the first embodiment, specifically as follows:

[0049] Figure 6 With Figure 8 It is shown that a water spray kettle 21 is fixed at one end of the sealing cover 14 far from the die cylinder 3. A spray head 22 is fixedly connected to the side end of the water spray kettle 21. The end of the spray head 22 far from the water spray kettle 21 does not contact the fan blade 16. A filter hole 23 is opened on the inner bottom wall of the collection tank 11. Storage grooves are opened at the ends of the first lifting plate 9 and the second lifting plate 10 away from each other. A water box 24 is movably inserted into the storage groove. The water box 24 communicates with the filter hole 23. A water pump is fixedly connected inside the water spray kettle 21;

[0050] The water outlet end of the water pump penetrates through the sealing cover 14 and is fixedly connected to the side end of the spray head 22. A water adding pipe is fixedly connected to the end of the water spray kettle 21 far from the sealing cover 14. The water adding pipe communicates with the water spray kettle 21. A pipe cap is movably sleeved on the end of the water adding pipe far from the water spray kettle 21.

[0051] After the materials fall from all the mechanisms at the upper end of the die cylinder 3, the materials will fly up in the space surrounded by the sealing cover 14 and a pair of collection tanks 11. To improve the speed of the materials gathering into the collection tank 11, the operator can start the water pump to spray the water in the water spray kettle 21 to wet the materials. Then, the materials will be mixed with the water mist and quickly fall into the collection tank 11, thereby reducing the speed of the materials falling into the collection tank 11 and further improving the processing efficiency;

[0052] Afterwards, the mixture of materials and water is filtered by the filter holes 23, enabling the water to pass through the filter holes 23 and drop into the water box 24. Finally, the water box 24 is taken out, and the water inside is taken out for purification and processing for recycling use.

Taking the perspective of the observer as the standard, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
