Description

Technical Field

[0001] The utility model relates to the technical field of polycarboxylate water reducer production, in particular to a polycarboxylate water reducer compounding production feeding device. Background Art

[0002] Polycarboxylate superplasticizer is a high-performance water reducer and a cement dispersant used in cement concrete. It is widely used in projects such as highways, bridges, dams, tunnels, and high-rise buildings. During production, raw materials and additives are fed into the production equipment through a feeding device. The raw materials are then processed into polycarboxylate superplasticizer using reactors and other production equipment.

[0003] During the production and feeding process of existing polycarboxylate water-reducing agents, measured materials, additives, and auxiliary agents are generally added all at once. If solid granular raw materials are present, large-scale one-time feeding can easily lead to the solid raw materials piling up in one place, resulting in greater resistance and increased load during subsequent mixing, and making subsequent mixing prone to incomplete. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a polycarboxylate water-reducing agent compounding production feeding device to solve the technical problems mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a polycarboxylate water-reducing agent compounding production feeding device, comprising a reactor and a device body, a motor is installed on the top of the device body, and a stirring shaft is connected to the output end of the motor, a turntable is sleeved on the outside of the stirring shaft, and a sealing gasket and a through hole are respectively provided on the top of the turntable, an anti-edge ring is connected to the bottom of the turntable, and a material storage cavity is opened on both sides of the inside of the device body, and a guide ring is fixed at the bottom of the material storage cavity.

[0006] By adopting the above technical solution, the motor drives the stirring shaft to rotate and mix the materials, additives or auxiliary agents, driving the turntable to rotate. The rotation of the turntable drives the sealing gasket and the through-hole to rotate. When the through-hole rotates to the bottom of a storage chamber, the materials, additives or auxiliary agents in the storage chamber are affected by gravity and pass through the through-hole into the reactor for mixing reaction. At the same time, the setting of the guide ring facilitates the material, additives or auxiliary agents in the storage chamber to be guided to the through-hole, reducing the residue in the storage chamber. The setting of the sealing gasket prevents the material, additives or auxiliary agents from filling the gap between the turntable and the device body, and prevents the material, additives or auxiliary agents from entering the gap between the turntable and the device body to cause blockage and waste. When liquid material, additives or auxiliary agents flow out of the through-hole, the anti-edge ring is set to prevent the liquid material, additives or auxiliary agents from dripping and will not flow along the bottom of the turntable.

[0007] Furthermore, the turntable is rotatably connected to the device body, and the sealing gasket is in contact with the bottom of the device body.

[0008] By adopting the above technical solution, the turntable rotates while driving the sealing gasket and the through hole to rotate. When the through hole rotates to the bottom of a storage cavity, the material, additives or auxiliary agents in the storage cavity are affected by gravity and pass through the through hole into the reactor for mixing reaction. The setting of the sealing gasket prevents the material, additives or auxiliary agents from filling the gap between the turntable and the device body, and prevents the material, additives or auxiliary agents from entering the gap between the turntable and the device body to cause blockage and waste.

[0009] Furthermore, two of the turntable and the sealing gasket are provided, and the turntable is detachably connected to the stirring shaft by bolts, and the device body is detachably connected to the reactor by bolts.

[0010] By adopting the above technical solution, the staff removes the bolts between the reactor and the device body, and then the staff can remove the device body from the top of the reactor. The staff removes the bolts between the turntable and the stirring shaft, and then the staff separates the turntable and the sealing gasket in half, and then the staff can replace the turntable and the sealing gasket.

[0011] Furthermore, the cross section of the anti-edge ring is a double triangle.

[0012] By adopting the above technical solution, the anti-edge ring is provided to prevent the liquid material, additive or auxiliary agent from dripping and flowing along the bottom of the turntable.

[0013] Furthermore, a discharge port is provided at the bottom of the reactor, and feed ports are connected to both sides of the device body.

[0014] By adopting the above technical solution, the measured raw materials are fed into the storage cavity through the feeding port by the feeding device, and after mixing, the materials are fed into the conveying device through the discharge port through the reactor.

[0015] Furthermore, the feed port, material storage cavity, guide ring, anti-edge ring and through hole are provided in plurality, and the plurality of feed ports, material storage cavity, guide ring, anti-edge ring and through hole are distributed in a ring array.

[0016] By adopting the above technical solution, since a plurality of feed ports, material storage chambers, guide rings, anti-edge rings and through holes are provided, it is convenient to feed a variety of materials, additives or auxiliary agents.

[0017] Furthermore, plugs are connected to both sides of the bottom of the turntable, and the plugs pass through the through holes.

[0018] By adopting the above technical solution, a number of plugs are installed in multiple through holes to adjust the speed of interval feeding. Assuming that there are six through holes and five plugs, only one through hole can be used for feeding. Therefore, the material, additive or auxiliary agent in each storage cavity is fed into the reactor once every time the turntable rotates one circle; assuming that there are six through holes and three plugs, only three through holes can be used for feeding. Therefore, the material, additive or auxiliary agent in each storage cavity is fed into the reactor three times every time the turntable rotates one circle.

[0019] Furthermore, a plurality of plugs are provided, and the plurality of plugs are detachably connected to the turntable via bolts.

[0020] By adopting the above technical solution, if the staff wants to adjust the number of plugs, the staff can directly install the plugs at the bottom of the turntable through the bolts, or remove the bolts on the plugs and then remove the plugs from the turntable, thereby completing the adjustment of the number of plugs.

[0021] Furthermore, a groove is provided on the top of the plug, and the anti-edge ring is adapted to the groove.

[0022] By adopting the above technical solution, since a groove is provided on the top of the plug, it is avoided that the plug is prevented from being pressed by the anti-edge ring during installation, which causes the plug to be unable to be installed.

[0023] In summary, the present invention has the following beneficial effects:

[0024] 1. The utility model is provided with a material storage chamber, a guide ring, a turntable, a sealing gasket, an anti-edge ring and a through hole. When the motor drives the stirring shaft to rotate and mixes the materials, additives or auxiliary agents, the turntable is driven to rotate. When the turntable rotates, the sealing gasket and the through hole are driven to rotate. When the through hole rotates to the bottom of a material storage chamber, the materials, additives or auxiliary agents in the material storage chamber are affected by gravity and fall through the through hole into the reactor for mixing reaction. At the same time, the material, additives or auxiliary agents in the material storage chamber are conveniently guided to the through hole by the setting of the guide ring, thereby reducing the amount of material, additives or auxiliary agents in the material storage chamber. The sealing gasket is provided to prevent materials, additives or auxiliary agents from filling the gap between the turntable and the device body, thereby preventing materials, additives or auxiliary agents from entering the gap between the turntable and the device body and causing blockage and waste. When liquid materials, additives or auxiliary agents flow out of the through-hole, the anti-edge ring is provided to prevent the liquid materials, additives or auxiliary agents from dripping and flowing along the bottom of the turntable. The material can be fed continuously at intervals to avoid excessive feeding at one time, which causes large resistance and uneven mixing, and no additional actuators such as motors are required to reduce costs.

[0025] 2. The utility model adjusts the speed of interval feeding by setting a plug and installing a plurality of plugs in a plurality of through holes. Assuming that there are six through holes and there are five plugs, only one through hole can be used for feeding. Therefore, the material, additive or auxiliary agent in each storage cavity is fed into the reactor once for each rotation of the turntable. Assuming that there are six through holes and there are three plugs, only three through holes can be used for feeding. Therefore, the material, additive or auxiliary agent in each storage cavity is fed into the reactor three times for each rotation of the turntable. This facilitates the adjustment of the feeding interval speed and increases flexibility. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] 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. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0034] The following describes an embodiment of the present invention based on its overall structure.

[0035] Example 1:

[0036] A polycarboxylate water reducer compounding production feeding device, such as Figures 1-6When the stirring rod 5 is rotated, the stirring rod 5 is rotated, and the stirring rod 5 is rotated, and the stirring rod 5 is rotated. When the stirring rod 5 is rotated, the stirring rod 5 is rotated, and the sealing gasket 9 and the through hole 11 are rotated. There are two rotating discs 8 and sealing gasket 9, and the rotating disc 8 is connected to the stirring shaft 5 by bolts. When the staff needs to replace the rotating disc 8 or the sealing gasket 9, the staff removes the bolts between the rotating disc 8 and the stirring shaft 5, and then the staff separates the rotating disc 8 and the sealing gasket 9 in half. After that, the staff can replace the rotating disc 8 and the sealing gasket 9; the top of the rotating disc 8 is respectively provided with a sealing gasket 9 and a through hole 11, and the rotating disc 8 drives the sealing gasket 9 and the through hole 11 to rotate. When the through hole 11 rotates to the bottom of a storage chamber 6, the material, additive or auxiliary agent in the storage chamber 6 is affected by gravity and passes through the through hole 11 into the reactor 1 for mixing reaction; the sealing gasket 9 is fitted with the bottom of the device body 2. The setting of the sealing gasket 9 prevents the material, additive or auxiliary agent from filling the gap between the turntable 8 and the device body 2, and prevents the material, additive or auxiliary agent from entering the gap between the turntable 8 and the device body 2 to cause blockage and waste; the bottom of the turntable 8 is connected to an anti-edge ring 10, and the cross-section of the anti-edge ring 10 is a double triangle. When liquid material, additive or auxiliary agent flows out of the through hole 11, the setting of the anti-edge ring 10 prevents the liquid material, additive or auxiliary agent from dripping and will not flow along the bottom of the turntable 8; the device body 2 is provided with storage chambers 6 on both sides, and a guide ring 7 is fixed at the bottom of the storage chamber 6. The setting of the guide ring 7 facilitates the material, additive or auxiliary agent in the storage chamber 6 to be guided to the through hole 11, thereby reducing the residue in the storage chamber 6.

[0037] See Figure 1 、 Figure 2 、 Figure 3 and Figure 6 In the above embodiment, a discharge port is provided at the bottom of the reactor 1. After mixing, the material is fed into the conveying device through the discharge port through the reactor 1, and then the mixed material is fed into the next process through the conveying device; feed ports 3 are connected to both sides of the device body 2, and the measured raw materials are fed into the storage chamber 6 through the feed port 3 through the feeding device; there are multiple feed ports 3, storage chamber 6, guide ring 7, anti-edge ring 10 and through hole 11, and the multiple feed ports 3, storage chamber 6, guide ring 7, anti-edge ring 10 and through hole 11 are distributed in a ring array, which is convenient for feeding a variety of materials, additives or auxiliary agents; the device body 2 is connected to the top of the reactor 1, and the device body 2 is detachably connected to the reactor 1 by bolts; it is convenient for disassembly and maintenance.

[0038] Example 2:

[0039] On the basis of the above embodiment 1, in order to facilitate the adjustment of the feeding interval speed and increase flexibility, the following settings are now adopted.

[0040] See Figure 2 、 Figure 3 and Figure 5 In the above embodiment, plugs 12 are connected to both sides of the bottom of the turntable 8, and the plugs 12 pass through the through holes 11. There are multiple plugs 12. When the turntable 8 drives the through holes 11 to rotate for interval feeding, a number of plugs 12 are installed in the multiple through holes 11 to adjust the speed of interval feeding. Assuming that there are six through holes 11 and there are five plugs 12, only one through hole 11 can be used for feeding. Therefore, the material, additives or auxiliary agents in each storage cavity 6 are added into the reactor 1 once every time the turntable 8 rotates one circle; multiple plugs 12 are detachably connected to the turntable 8 by bolts, and a groove is provided on the top of the plug 12, and the anti-edge ring 10 is adapted to the groove. The staff can directly install the plug 12 at the bottom of the turntable 8 by bolts, or remove the bolts on the plug 12 and then remove the plug 12 from the turntable 8, thereby completing the adjustment of the number of plugs 12.

[0041] The implementation principle of the present utility model is as follows: first, the staff connects the feeding device with the feeding port 3, and then connects the conveying device with the discharge port at the bottom of the reactor 1. After that, the staff uses the feeding device to feed the measured raw materials into the storage chamber 6 through the feeding port 3. After that, the staff turns on the motor 4. After the motor 4 starts, the output end drives the stirring shaft 5 to rotate;

[0042] When the stirring shaft 5 rotates, the turntable 8 is driven to rotate, and the turntable 8 is driven to rotate while the sealing gasket 9 and the through hole 11 are rotated. When the through hole 11 rotates to the bottom of a storage chamber 6, the material, additive or auxiliary agent in the storage chamber 6 is affected by gravity and passes through the through hole 11 and falls into the reactor 1 for mixing reaction. At the same time, the setting of the guide ring 7 facilitates the material, additive or auxiliary agent in the storage chamber 6 to be guided to the through hole 11, thereby reducing the residue in the storage chamber 6, and the setting of the sealing gasket 9 prevents the material, additive or auxiliary agent from filling the space between the turntable 8 and the device body 2. The gap between the turntable 8 and the main body 2 of the device is formed to prevent the material, additive or auxiliary agent from entering the gap between the turntable 8 and the device body 2 to cause blockage and waste. When the liquid material, additive or auxiliary agent flows out of the through hole 11, the anti-edge ring 10 is provided to prevent the liquid material, additive or auxiliary agent from dripping and flowing along the bottom of the turntable 8. Then, the material, additive and auxiliary agent put into the reactor 1 are mixed and reacted by the rotating stirring shaft 5. After the mixing is completed, the material is sent to the conveying device through the discharge port of the reactor 1, and then the mixed material is sent to the next process by the conveying device;

[0043] When the turntable 8 drives the through holes 11 to rotate for intermittent feeding, a plurality of plugs 12 are inserted into the through holes 11 to adjust the speed of intermittent feeding. Assuming that there are six through holes 11 and five plugs 12, only one through hole 11 can be used for feeding. Therefore, the material, additive or auxiliary agent in each storage cavity 6 is fed into the reactor 1 once for each rotation of the turntable 8. Furthermore, assuming that there are six through holes 11 and three plugs 12, only three through holes 11 can be used for feeding. Therefore, the material, additive or auxiliary agent in each storage cavity 6 is fed into the reactor 1 three times for each rotation of the turntable 8.

[0044] When it is necessary to adjust the number of plugs 12 or replace a worn structure, the staff removes the bolts between the reactor 1 and the device body 2, and then the staff can remove the device body 2 from the top of the reactor 1. If the staff wants to adjust the number of plugs 12 at this time, the staff can directly install the plugs 12 at the bottom of the turntable 8 through the bolts, or remove the bolts on the plugs 12 and then remove the plugs 12 from the turntable 8, thereby completing the adjustment of the number of plugs 12; when the staff needs to replace the turntable 8 or the sealing gasket 9, the staff removes the bolts between the turntable 8 and the stirring shaft 5, and then the staff separates the turntable 8 and the sealing gasket 9 in half, and then the staff can replace the turntable 8 and the sealing gasket 9. After the replacement is completed, the staff fits the turntable 8 split in half and puts it on the outside of the stirring shaft 5, and then the staff screws in the bolts to limit the turntable 8. Finally, the staff puts the device body 2 back on the top of the reactor 1 and screws in the bolts to tighten the limit.

The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
