Description

Technical Field

[0001] The utility model relates to the technical field of water reducing agent preparation, in particular to equipment for preparing polycarboxylic acid water reducing agent. Background Art

[0002] Water reducing agent refers to an admixture that can reduce the amount of mixing water and improve the strength of concrete while keeping the workability and cement dosage unchanged, or save cement dosage while keeping the workability and strength unchanged. It is widely used in projects such as roads, bridges, dams, tunnels and high-rise buildings.

[0003] When preparing polycarboxylic acid water-reducing agent, the existing production equipment usually stirs by simple stirring blades in the polymerization reactor. The stirring method is single and the stirring effect is poor, and the materials cannot be mixed together quickly and thoroughly. To this end, we propose a device for preparing polycarboxylic acid water-reducing agent. Utility Model Content

[0004] In view of the shortcomings of existing production equipment, such as a single stirring mode, poor stirring effect, and inability to quickly and thoroughly mix the materials together, the utility model provides a device for preparing polycarboxylic acid water reducer, which has the advantages of fully mixing the water reducer raw materials and ensuring the preparation yield, thereby solving the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] A device for preparing a polycarboxylate water-reducing agent comprises a reactor rotatably connected between two supports, the supports are vertically connected to the top of a base, a sealing cover is sealed at the top of the reactor, the bottom of the reactor is sealed by a bottom cover, a plurality of feed pipes are arranged at the top of the sealing cover, and a discharge pipe is connected to the lower end of the reactor;

[0007] An annular seat is connected to the outer wall of the reactor through a bearing, and a first connecting seat and a second connecting seat are symmetrically connected to the annular seat. The first connecting seat and the second connecting seat are rotatably connected to the support through a rotating shaft. A first motor is fixedly connected in the first connecting seat, and a gear is fixedly connected to the output end of the first motor. A plurality of tooth plates are connected to the outer wall of the reactor along the circumferential direction, and the gears and the tooth plates are meshingly connected.

[0008] Optionally, a second motor is fixedly connected to the outer wall of one of the supports, and a sprocket is fixedly connected to the rotating shaft connected to the second connecting seat and the output end of the second motor, and the two sprockets are connected by a chain.

[0009] Optionally, a connecting shaft is rotatably connected between the sealing cover and the bottom cover, the upper end of the connecting shaft extends to the top of the sealing cover and is fixedly connected to a third motor, and the upper end of the connecting shaft located in the reactor is fixedly connected to a stirring rod.

[0010] Optionally, a spiral blade is fixedly connected to the connecting shaft at the lower end of the reactor.

[0011] Optionally, the first connecting seat is a C-shaped seat and the second connecting seat is an L-shaped seat.

[0012] Optionally, a control box is fixedly connected to the outer wall of one of the supports, a controller is disposed in the control box, and the first motor, the second motor, and the third motor are all connected to the controller.

[0013] Compared with the prior art, the utility model can drive the reactor to rotate circumferentially in the annular seat and reciprocate between the supports through the simultaneous rotation of the third motor, the first motor and the second motor. Moreover, since the circumferential rotation directions of the stirring rod and the reactor are opposite, the internal raw materials can be effectively mixed. The spiral blades can improve the discharge effect and improve the practicability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1 to Figure 2 The utility model provides a technical solution: an apparatus for preparing polycarboxylic acid water-reducing agent, comprising a reactor 7 rotatably connected between two supports 4, the supports 4 being vertically connected to the top of a base 15, a sealing cover 13 being sealed at the top of the reactor 7, the bottom of the reactor 7 being sealed by a bottom cover 8, and a plurality of feed pipes 2 being arranged at the top of the sealing cover 13, and a discharge pipe 9 being connected at the lower end of the reactor 7.

[0019] like Figure 2 As shown, a second motor 11 is fixedly connected to the outer wall of one of the supports 4, and a sprocket 12 is fixedly connected to the rotating shaft 20 connected to the second connecting seat 10 and the output end of the second motor 11. The two sprockets 12 are connected by a chain. The rotation of the second motor 11 drives the two sprockets 12 to rotate simultaneously, and then drives the reactor 7 to reciprocate between the two supports 4, thereby achieving the effect of mixing the raw materials in the reactor 7.

[0020] like Figure 1 , 2 As shown, in order to further improve the mixing efficiency of the raw materials inside the reactor 7, an annular seat 6 is connected to the outer wall of the reactor 7 through a bearing, and a first connecting seat 1 and a second connecting seat 10 are symmetrically connected to the annular seat 6, the first connecting seat 1 is a C-shaped seat and the second connecting seat 10 is an L-shaped seat, the first connecting seat 1 and the second connecting seat 10 are rotatably connected to the support 4 through a rotating shaft 20, a first motor 5 is fixedly connected in the first connecting seat 1, a gear 3 is fixedly connected to the output end of the first motor 5, a plurality of tooth plates 16 are connected to the outer wall of the reactor 7 along the circumferential direction, the gear 3 and the tooth plate 16 are meshed and connected, and the first motor 5 rotates to realize the rotation of the reactor 7 in the annular seat 6, and at the same time, with the cooperation of the second motor 11, the raw materials can be further fully mixed.

[0021] At the same time, in order to ensure that the raw materials inside the reactor 7 are stirred and mixed, Figure 2 As shown, a connecting shaft 19 is rotatably connected between the sealing cover 13 and the bottom cover 8, the upper end of the connecting shaft 19 extends to the top of the sealing cover 13 and is fixedly connected to the third motor 14, the upper end of the connecting shaft 19 located in the reactor 7 is fixedly connected to a stirring rod 18, and the connecting shaft 19 located at the lower end of the reactor 7 is fixedly connected to a spiral blade 17, a control box 21 is fixedly connected to the outer wall of one of the supports 4, a controller is arranged in the control box 21, the first motor 5, the second motor 11, and the third motor 14 are all connected to the controller.

At the same time, the stirring rod 18 rotates in the opposite direction to the circumferential direction of the reactor 7, which can effectively achieve sufficient mixing of the internal raw materials. In actual use, a solenoid valve is installed on the discharge pipe 9, and at the same time, the spiral blade 17 can improve the discharge effect, thereby effectively improving the practicability of the device.
