Description

Technical Field

[0001] This utility model relates to a polycarboxylate superplasticizer processing equipment for concrete, specifically a polycarboxylate superplasticizer processing equipment for concrete, belonging to the technical field of polycarboxylate superplasticizer processing equipment. Background Technology

[0002] Polycarboxylate superplasticizer is a high-performance water-reducing agent and a cement dispersant used in cement concrete. It is widely used in highway, bridge, dam, tunnel, and high-rise building projects. This product is environmentally friendly, non-flammable, non-explosive, and safe for transport by train and truck.

[0003] Existing polycarboxylate superplasticizer processing equipment has the following disadvantages: 1. During continuous processing, the raw materials are stirred and mixed, and some raw materials adhere to the inner surface or bottom of the inner shell, resulting in uneven mixing; 2. When the external temperature is low, the mixing effect of the raw materials is not good. Therefore, improvements are made to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a polycarboxylate superplasticizer processing device for concrete in order to solve the above problems. The suction pipe extracts the raw material from the bottom of the inner shell and then transports it to the top. The rotating scraper can make the raw material evenly mixed. The components inside the outer shell can heat and keep the polycarboxylate superplasticizer in the inner shell.

[0005] This utility model achieves the above-mentioned objectives through the following technical solution: a polycarboxylate superplasticizer processing equipment for concrete, comprising an inner shell, an outer shell installed on the outside of the inner shell, a heat insulation pad adhered inside the outer shell, the heat insulation pad being located outside the heat insulation pad, the heat insulation pad being located outside the heating wire, the heating wire being wound around the outer surface of the inner shell, a rotating shaft rotatably connected to the inner shell, a suction tube installed on the rotating shaft, an opening at the bottom end of the suction tube, a stirring rod installed on the rotating shaft, the suction tube communicating with the rotating shaft, the rotating shaft being connected to a pipe through a rotary joint, a pump body installed on the pipe, the pump body communicating with a ring pipe, and the ring pipe being installed inside the inner shell.

[0006] Preferably, the inner shell is equipped with a material box, and a temperature sensor is installed at the top inner side of the inner shell.

[0007] Preferably, the pump body is mounted at the top of the inner shell, and the annular tube is fitted with a nozzle.

[0008] Preferably, a motor is installed at the bottom of the inner shell, and a rotating shaft is fixedly connected to the output end of the motor.

[0009] Preferably, a vertical groove is provided inside the rotating shaft, and the vertical groove is connected to the straw.

[0010] Preferably, the rotating shaft is equipped with a scraper, and the scraper is slidably connected to an inner shell.

[0011] Preferably, the pump body, temperature sensor, heating wire, and motor's current input terminals are electrically connected to an external power source via wires.

[0012] The beneficial effects of this utility model are:

[0013] The suction tube extracts the raw material from the bottom of the inner shell and transports it upwards. Working in conjunction with the rotating scraper, it ensures uniform mixing. The polycarboxylate superplasticizer raw material is fed into the inner shell through a hopper. The motor rotates, driving the suction tube and stirring rod connected to the rotating shaft to mix the raw material. Simultaneously, the scraper connected to the rotating shaft continuously scrapes the inner surface and bottom of the inner shell, separating the raw material adhering to the bottom and inner shell surface. During continuous mixing, the pump starts. The pump body is connected to the rotating shaft via a rotary joint. The rotating shaft has vertical grooves that communicate with the suction tube. Multiple openings at the bottom of the suction tube generate suction, drawing the raw material from the bottom of the inner shell into the vertical grooves. The material is then pumped into the ring pipe and sprayed downwards through nozzles at the bottom of the ring pipe. The stirring rod then further mixes the material, continuously transporting it upwards for mixing, resulting in excellent mixing.

[0014] The internal components of the outer shell work together to heat and insulate the polycarboxylate superplasticizer inside the shell. When the outside temperature is low, the temperature sensor inside the shell detects the temperature of the raw material. When the detected temperature is lower than the set temperature, the heating wire wrapped around the outside of the shell is energized to generate heat. The generated heat is transferred outward to heat the polycarboxylate superplasticizer raw material inside the shell. The motor continuously drives the stirring rod on the rotating shaft to stir and mix the raw material. The heating wire is located inside the heat insulation pad, which is made of alumina fiber. The heat insulation pad has low thermal conductivity and low heat melt, and good thermal insulation performance, which can reduce the heat loss from the heating wire. The heat insulation pad is located inside the insulation pad, which is made of aluminum silicate fiber. It has low thermal conductivity, excellent thermal stability and chemical stability, and good thermal insulation performance, which can provide a good insulation effect. The polycarboxylate superplasticizer raw material can be stirred at a suitable temperature by the combination of the heating wire, heat insulation pad and insulation pad. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please refer to Example 1 Figure 1-4 As shown, a polycarboxylate superplasticizer processing device for concrete includes an inner shell 4, with an outer shell 3 installed on the outside of the inner shell 4. The outer shell 3 can fix the position of the inner shell 4. A thermal insulation pad 8 is adhered inside the outer shell 3. Both the thermal insulation pad 8 and the heat insulation pad 9 have good heat insulation effects. The thermal insulation pad 8 is located outside the heat insulation pad 9, and the heat insulation pad 9 is located outside the heating wire 10. The heating wire 10 is wound around the outer surface of the inner shell 4. When the heating wire 10 is energized, it can heat the polycarboxylate superplasticizer inside the inner shell 4. The inner shell 4 is rotatably connected to a rotating shaft 14, and a suction tube 11 is installed on the rotating shaft 14. The rotation drives the connected straw 11 to rotate. The bottom end of the straw 11 has an opening 17. The straw 11 can extract the polycarboxylate superplasticizer at the bottom end of the inner shell 4. The rotating shaft 14 is equipped with a stirring rod 13. The rotation of the rotating shaft 14 drives the connected stirring rod 13 to rotate. The straw 11 and the rotating shaft 14 are interconnected. The rotating shaft 14 is connected to the pipe 5 through a rotary joint. The pipe 5 is equipped with a pump body 2. The pump body 2 extracts the polycarboxylate superplasticizer through the rotating shaft 14 connected to the pipe 5. The pump body 2 is interconnected with the ring pipe 6. The ring pipe 6 is installed inside the inner shell 4 and at the top of the inner shell 4.

[0022] Specifically, the inner shell 4 is equipped with a material box 1, through which raw materials are conveyed into the inner shell 4. A temperature sensor 7 is installed at the top inner side of the inner shell 4, which can detect the temperature inside the inner shell 4.

[0023] Specifically, the pump body 2 is installed at the top of the inner shell 4, and the inner shell 4 can fix the position of the pump body 2. The annular pipe 6 is equipped with a nozzle 15, and the polycarboxylate superplasticizer in the annular pipe 6 is sprayed out through the nozzle 15.

[0024] Specifically, a motor 12 is installed at the bottom of the inner shell 4, and a rotating shaft 14 is fixedly connected to the output end of the motor 12. The rotation of the motor 12 drives the connected rotating shaft 14 to rotate.

[0025] Specifically, a vertical groove 16 is provided inside the rotating shaft 14. The vertical groove 16 facilitates the flow of polycarboxylate superplasticizer. The vertical groove 16 is interconnected with the suction tube 11, and the polycarboxylate superplasticizer in the suction tube 11 is transported into the vertical groove 16.

[0026] Specifically, the current input terminals of the pump body 2, temperature sensor 7, heating wire 10 and motor 12 are electrically connected to an external power source through wires, and the external power source provides power to the pump body 2, temperature sensor 7, heating wire 10 and motor 12.

[0027] Example 2: Please refer to Figure 1-2 The difference between this embodiment and embodiment 1 is that: the rotating shaft 14 is equipped with a scraper 18, and the scraper 18 is slidably connected to the inner shell 4. The rotation of the rotating shaft 14 drives the connected scraper 18 to rotate, scraping the inner surface of the inner shell 4.

[0028] In use, the polycarboxylate superplasticizer raw material is fed into the inner shell 4 through the material box 1. The motor 12 rotates, driving the suction pipe 11 and stirring rod 13 connected to the rotating shaft 14 to rotate, mixing the raw material. At the same time, the scraper 18 connected to the rotating shaft 14 continuously scrapes the inner surface and bottom of the inner shell 4, separating the raw material adhering to the bottom and the surface of the inner shell 4 from the inner shell 4. During the continuous stirring process, the pump body 2 starts. The pipe 5 connected to the pump body 2 is connected to the rotating shaft 14 through a rotary joint. The rotating shaft 14 has a vertical groove 16, which is interconnected with the suction pipe 11. That is, the suction force generated at the multiple openings 17 at the bottom of the suction pipe 11 can draw the raw material at the bottom of the inner shell 4 into the vertical groove 16 and transport it into the ring pipe 6 through the pump body 2. It is then sprayed downward through the nozzle 15 at the bottom of the ring pipe 6 and can be stirred and mixed again by the stirring rod 13. The raw material at the bottom can be continuously transported upward for stirring, resulting in good mixing effect. When the ambient temperature is low, the temperature sensor 7 inside the inner shell 4 detects the temperature of the raw material inside the inner shell 4. When the detected temperature is lower than the set temperature, the heating wire 10 wrapped around the outer side of the inner shell 4 is energized to generate heat. The generated heat is transferred outward to heat the polycarboxylate superplasticizer raw material inside the inner shell 4. The motor 12 continuously drives the stirring rod 13 on the rotating shaft 14 to rotate and stir the raw material. The heating wire 10 is located inside the heat insulation pad 9. The heat insulation pad 9 is made of alumina fiber, which has low thermal conductivity and heat melt, and good heat insulation performance, which can reduce the heat loss of the heating wire 10. The heat insulation pad 9 is located inside the insulation pad 8. The insulation pad 8 is made of aluminum silicate fiber, which has low thermal conductivity, excellent thermal stability and chemical stability, and good heat insulation performance, which can play a good heat preservation effect. The polycarboxylate superplasticizer raw material can be stirred at a more suitable temperature by the combination of the heating wire 10, the heat insulation pad 9 and the insulation pad 8.
