Description

Technical Field

[0001] This utility model relates to the field of evaporation crystallization technology, and in particular to a low-temperature evaporation crystallization device with an anti-clogging structure. Background Technology

[0002] The working principle of low-temperature evaporation crystallization equipment is mainly to heat the solution to a certain temperature to make it evaporate, and then condense the evaporated gas to make it into a solid, thereby separating the solute. It is widely used in many industries such as chemical, pharmaceutical, food, and metallurgy.

[0003] Low-temperature evaporation crystallization equipment uses crystallization tanks for crystallization and discharge operations during production. Traditional crystallization tanks are prone to clogging during discharge. Due to the lack of auxiliary mechanisms for discharge and the different crystallization characteristics, crystals tend to accumulate at the pipe opening. Therefore, there is an urgent need for a low-temperature evaporation crystallization equipment with an anti-clogging structure. Utility Model Content

A rotating seat is assembled in the middle of the crystallization discharge pipe through an installation ring. Multiple flow dividers are inclinedly arranged on the inner wall of the rotating seat, and one end of the flow divider extends out of the rotating seat.

[0010] Furthermore, in a preferred configuration, a slot is provided on one side of the crystallization discharge pipe to assemble the mounting ring, and a mating groove is provided on the inner side of the mounting ring to mate with the rotating seat.

[0011] Furthermore, in a preferred configuration, the outer wall of the mounting ring is provided with an external toothed ring, one side of which meshes with a drive gear. The drive gear is driven to rotate by a drive motor, which is installed on the outside of the crystallization discharge pipe.

[0012] In addition, a preferred structure is that a second discharge pipe is provided on one side of the bottom of the crystallization discharge pipe, and the second discharge pipe is connected to the inside of the crystallization discharge pipe to discharge the material.

[0013] In addition, a preferred structure is that a limiting ring is provided on one side of the inside of the crystallization discharge pipe, and a rotating seat is provided on the side away from the limiting ring.

[0014] In addition, a preferred structure is that an air inlet pipe is provided on one side of the upper part of the crystallization discharge pipe, one end of the air inlet pipe is connected to the air passage, and the other end of the air passage is connected to the inside of the limiting ring. The inside of the limiting ring is hollow, and multiple air outlet holes are provided on the side of the limiting ring facing the discharge pipe.

[0015] In addition, a preferred structure is that a cylinder is provided on one side of the crystallization discharge pipe, the telescopic end of the cylinder extends into the crystallization discharge pipe and is connected to a block, the block moves horizontally within the crystallization discharge pipe to control the discharge of the crystallization discharge pipe.

[0016] The beneficial effects of this utility model are as follows:

[0017] I. In this utility model, the rotating seat inside the crystallization discharge pipe is driven by a drive motor to rotate at a uniform speed.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-5 A low-temperature evaporation crystallization device with an anti-clogging structure includes a low-temperature evaporation crystallization tank 1. One end of the low-temperature evaporation crystallization tank 1 is connected to a crystallization discharge pipe 2. A rotating seat 7 is assembled in the middle of the crystallization discharge pipe 2 through an installation ring 8. Multiple diverting plates 6 are inclinedly arranged on the inner wall of the rotating seat 7. One end of the diverting plate 6 extends out of the rotating seat 7.

[0027] Furthermore, a plurality of snap-fit ​​strips 71 are provided on one outer wall of the rotating seat 7, and one end of the rotating seat 7 is limited and locked in the locking groove 83 opened in the inner wall of the mounting ring 8 by the snap-fit ​​strips 71.

[0028] Furthermore, a magnetic pad 10 is provided at one end of the rotating seat 7 facing the mounting ring 8, and a magnetic absorbing piece 9 is provided on the side of the mounting ring 8 facing the rotating seat 7. The magnetic absorbing piece 9 and the magnetic pad 10 are magnetically connected to each other to realize the mutual connection between the rotating seat 7 and the mounting ring 8.

[0029] Furthermore, the mounting ring 8 is driven to rotate by the drive motor 13, and the mounting ring 8 synchronously drives the rotating seat 7 to rotate.

[0030] A slot is provided on one side of the crystallization discharge pipe 2 to assemble the mounting ring 8, and a mating groove 82 is provided on the inner side of the mounting ring 8 to mate with the rotating seat 7.

[0031] An external toothed ring 81 is provided on the outer wall of the mounting ring 8. One side of the external toothed ring 81 is meshed with the drive gear 131. The drive gear 131 is driven to rotate by the drive motor 13, which is installed on the outside of the crystallization discharge pipe 2.

[0032] A discharge pipe 4 is provided on one side of the bottom of the crystallization discharge pipe 2. The discharge pipe 4 is connected to the inside of the crystallization discharge pipe 2 to discharge the material.

[0033] A limiting ring 11 is provided on one side of the inside of the crystallization discharge pipe 2, and a rotating seat 7 is provided on the side away from the limiting ring 11.

[0034] A gas inlet pipe 5 is provided on one side of the upper part of the crystallization discharge pipe 2. One end of the gas inlet pipe 5 is connected to the gas channel 51, and the other end of the gas channel 51 is connected to the inside of the limiting ring 11. The inside of the limiting ring 11 is hollow, and multiple air outlets 12 are provided on the side of the limiting ring 11 facing the discharge pipe 4.

[0035] Among them, the gas inlet pipe 5 is connected to an external gas source to introduce gas.

The telescopic end of the cylinder 3 extends into the crystallization discharge pipe 2 and is connected to a block 31. The block 31 moves horizontally within the crystallization discharge pipe 2 to control the discharge of the crystallization discharge pipe 2.

[0037] In this embodiment, by controlling the extension and retraction of the cylinder component 3 to drive the block block 31 to move, the block block 31 disengages from the limiting ring 11, allowing the material to flow and be discharged. During this process, the drive motor 13 drives the mounting ring 8 to rotate, and simultaneously drives the rotating seat 7 to rotate. The multiple diversion plates 6 set in the rotating seat 7 can divert and guide the material to prevent it from accumulating together, and further improve the anti-blocking effect under the action of rotation.

[0038] An external gas source device sends gas into the gas inlet pipe 5 and into the limiting ring 11 through the gas channel 51. The limiting ring 11 is hollow inside and the gas is discharged through the gas outlet 12 on one side. The gas discharge direction is the same as the material discharge direction, which plays a role in assisting material discharge and preventing material from accumulating and adhering to the pipe wall.

[0039] Meanwhile, with prolonged use, in order to prevent material from adhering to the rotating seat 7 and the diverter plate 6, the rotating seat 7 is pulled outward to disengage the locking strip 71 from the locking groove 83 inside the mounting ring 8, and the magnetic suction plate 9 and the magnetic pad 10 are disengaged accordingly, thereby enabling quick maintenance of the rotating seat 7.

[0040] It is worth noting that the specific operation mode and structural composition of the low-temperature evaporation crystallization equipment are existing technologies, and those skilled in the art are familiar with its working principle, so they will not be explained in detail.
