Description

Technical Field

[0001] This utility model relates to the technical field of drying equipment for finished water-reducing agents, specifically a fast screening and drying equipment for finished water-reducing agents. Background Technology

[0002] Water-reducing agents are concrete admixtures that reduce the amount of mixing water while maintaining a relatively constant concrete slump. Most are anionic surfactants, including lignin sulfonates, naphthalene sulfonates, and formaldehyde polymers. The finished water-reducing agent (usually a liquid or paste that has undergone preliminary dehydration) needs to be dried to reduce moisture content (typically ≤3%) and then sieved to achieve particle size classification (e.g., 80-200 mesh).

[0003] However, traditional processes suffer from problems such as separate drying and screening operations and low efficiency. Therefore, a fast screening and drying device for water-reducing agent products is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a fast sieving and drying device for finished water-reducing agents. This device achieves the drying process of the finished water-reducing agent during the forward pushing process by the back-and-forth swing of the sieve plate mechanism in conjunction with the blower mechanism, realizing continuous drying and sieving operation. Under the action of the up-and-down vibrating sieve plate structure, not only is the sieving operation of the sieve plate structure accelerated, but the drying efficiency of the finished water-reducing agent is also accelerated.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid sieving and drying device for finished water-reducing agents, comprising: a frame; a blower mechanism and a vibrating screen mechanism disposed on and below the frame for drying the finished water-reducing agent; wherein the vibrating screen mechanism includes a base plate fixed to the lower part of the frame, a plurality of vibrating supports disposed on the base plate; and a sieve plate structure installed on the plurality of vibrating supports, wherein under the vibration action of the vibrating supports moving back and forth and up and down, the plurality of sieve plate structures can drive the finished water-reducing agent placed on them to rapidly sieve and convey it forward.

Detailed Implementation

[0023] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. The various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0024] Example 1

[0025] Please see Figures 1 to 6The present invention preferably provides the following technical solution: a rapid sieving and drying device for finished water-reducing agents, comprising: a frame 111; a blower mechanism and a vibrating sieve mechanism disposed on and below the frame 111 for drying the finished water-reducing agent; wherein, the vibrating sieve mechanism includes a base plate 311 fixed to the lower part of the frame 111, a plurality of vibrating supports disposed on the base plate 311; and a sieve plate structure mounted on the plurality of vibrating supports, wherein under the vibration action of the vibrating supports, the plurality of sieve plate structures can drive the finished water-reducing agent placed on them to be rapidly sieved and conveyed forward.

[0026] In this embodiment, the frame 111 has a blower mechanism and a vibrating screen mechanism installed at its upper and lower parts, respectively. Figure 2 , 3 As shown in Figure 5, when the finished water-reducing agent is placed on the surface of the vibrating screen mechanism, the vibrating support of the vibrating screen mechanism causes the screen plate structure to swing back and forth. The back and forth swing allows the screen plate structure to push the finished water-reducing agent forward. At this time, the blower mechanism can dry the finished water-reducing agent. On the other hand, the vibrating support synchronously drives the screen plate structure to vibrate up and down. This process not only accelerates the screening operation of the screen plate structure, but also accelerates the drying efficiency of the finished water-reducing agent.

[0027] Furthermore, a recycling frame 112 is installed in front of the frame 111 along the direction of the finished water-reducing agent product's movement, for receiving the finished water-reducing agent product, in conjunction with... Figure 1 , 5 As shown.

[0028] Furthermore, each set of vibration supports includes a pneumatic lifting structure mounted on the base plate 311, with a U-shaped frame 313 mounted on the telescopic end of the pneumatic lifting structure; several crossbars 314 telescopically mounted on both sides of the U-shaped frame 313; and an assembly frame 315 fixed to the opposite ends of the two sets of crossbars 314. Each of the crossbars 314 has a first spring 316 sleeved on its outer periphery, and both ends of each first spring 316 are fixed to the opposite surfaces of the assembly frame 315 and the base plate 311. Several vertical rods 317 are also fixed to both sides of the assembly frame 315. A transmission block 318 is sleeved between the two sets of vertical rods 317. Each vertical rod 317 has a second spring 319 sleeved at both its upper and lower ends, and both ends of each second spring 319 are fixed to the opposite surfaces of the assembly frame 315 and the transmission block 318. The assembly also includes a cam transmission assembly mounted on the transmission block 318 for driving the transmission block 318 to rotate eccentrically.

[0029] Furthermore, the cam transmission assembly includes a transmission shaft 320 rotatably mounted in the middle of the transmission block 318, wherein one end of the transmission shaft 320 is fixed to the cam body 321, and the other end passes through a through hole opened in the side wall of the frame 111 and is fixed to the motor output end provided in the side wall of the frame 111.

[0030] like Figure 5 ,6 As shown, the assembly frame 315 is fixed to the opposite ends of several horizontal bars 314 respectively arranged on both sides of the U-shaped frame 313, while the transmission block 318 is sleeved on the vertical bars 317 respectively arranged on both sides of the assembly frame 315. In conjunction with the first spring 316 sleeved on the horizontal bars 314 and the second spring 319 sleeved on the vertical bars 317, when the cam transmission assembly in the middle of the transmission block 318 is running—specifically, when the cam body 321 where the cam transmission assembly is located rotates—it can drive the transmission block 318 to move longitudinally on the several vertical bars 317, and simultaneously drive the assembly frame 315 to move laterally on the several horizontal bars 314. This achieves vibration operation of the transmission block 318 in four directions (up, down, left, and right), thereby driving the sieve plate structure connected to the transmission block 318 to vibrate in the up and down direction and in the forward and backward direction (same direction as above). Figure 6 The swinging process (shown in the left and right directions).

[0031] Example 2

[0032] As another embodiment of this utility model, the sieve plate structure includes a sieve frame 324, and a mounting part 323 is provided at the bottom of the sieve frame 324 corresponding to a plurality of vibration supports; and a transmission rod 322 rotatably mounted on each mounting part 323, wherein the transmission rod 322 is connected to the middle of the transmission block 318 where its corresponding vibration support is located; further, a plurality of sieve holes 325 are provided on the sieve frame 324.

[0033] The preferred vibrating supports of this application are two sets, and the two mounting parts 323 at the bottom of the screen frame 324 are rotatably mounted to the transmission rods 322 on the transmission blocks 318 where the two vibrating supports are located. When the transmission blocks 318 vibrate in four directions (up, down, left, and right), the screen frame 324 can be synchronously driven to vibrate up and down and swing back and forth. The up and down vibration, combined with the several screen holes 325 opened on the screen frame 324, can accelerate the screening operation. Figure 5 As shown, the back-and-forth swinging motion can push the water-reducing agent product placed on the screen frame 324 toward the recycling frame 112.

[0034] Example 3

[0035] As another embodiment of the present invention, the pneumatic lifting structure includes a cylinder 312 mounted on the surface of the base plate 311.

[0036] Combination Figure 5 , 6 As shown, in order to adjust the wind force received by the finished water-reducing agent, this application adjusts the distance between the screen frame 324 and the blower structure to match the shape of the assembly box 211. Under the rotation characteristics of the cylinder 312, the transmission rod 322 and the mounting part 323, the slope of the screen frame 324 is adjusted.

[0037] Example 4

[0038] As another embodiment of this utility model, the blower mechanism includes an assembly box 211 fixed on the upper part of the frame 111, and a plurality of air outlets 213 are provided at the bottom of the assembly box 211 aligned with the screen frame 324; and an air supply device 212 installed on the top of the assembly box 211 for supplying air to the plurality of air outlets 213; furthermore, a plurality of air guide plates 214 are also provided at the bottom of the assembly box 211, wherein the plurality of air guide plates 214 and the plurality of air outlets 213 are distributed at intervals.

[0039] The gas supply device 212 provided in this embodiment is a mature existing technology and will not be described in detail here.

[0040] Combination Figure 2 , 3 As shown in Figure 5, the air supply device 212, the assembly box 211, and the air outlet 213 are connected in sequence. When the air supply device 212 is running, the air outlets 213 can blow hot air onto the water-reducing agent finished product on the surface of the sieve frame 324 to realize the drying process of the water-reducing agent finished product. In order to increase the circulation time of hot air, this application provides an air guide plate 214 between adjacent air outlets 213 to extend the drying time.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Among these, there are various methods of detachable installation, such as using a combination of plug-in and snap-fit, or using bolt connections, etc.
