Description

Technical Field

[0001] The utility model relates to the technical field of material concentration, in particular to an automatic adding device for preventing overflow of a pot and defoaming agent. Background Art

[0002] In the chemical industry, biopharmaceuticals and other fields, when materials need to be concentrated to a concentration suitable for the production of products, as the water evaporates from the concentrated materials, it is often easy to overflow the pot. Defoamers are usually added to eliminate foam to avoid overflow.

[0003] When adding reagents manually, the amount of on-site work is large; when there is a sudden change in the working condition or a large amount of foaming, it is very easy for the slurry to overflow due to the untimely reaction of the personnel, which can easily cause harm to the operators and easily cause impact and damage to the environment, causing irreparable losses to the enterprise.

[0004] Therefore, it is necessary to propose an automatic adding device for preventing overflow of defoaming agent to solve the above problems. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] The purpose of the utility model is to provide an accurate and rapid automatic adding device for preventing overflow of defoaming agent without manual control, so as to solve the problems raised in the above-mentioned background technology.

The valve stem is slidably connected to the valve body and is driven to slide by a hollow float through a transmission mechanism.

[0010] Furthermore, when the hollow float rises, the hollow float drives the sealing plug away from the convergence hole; when the hollow float descends, the hollow float drives the sealing plug close to the convergence hole.

[0011] Furthermore, the valve stem passes through the convergence hole, and the diameter of the convergence hole is larger than the diameter of the valve stem.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] See also Figure 1-4 As shown, an automatic adding device for anti-overflow defoaming agent comprises a metering barrel 1, the bottom end of the metering barrel 1 is connected to a pipe 3, a flow valve 2 and a manual valve 4 are arranged on the pipe 3, and a float valve 5 is connected to the end of the pipe 3 away from the metering barrel 1. The float valve 5 is configured such that when a hollow float 16 rises, the float valve 5 opens, and when the hollow float 16 falls, the float valve 5 closes.

[0028] The flow rate of pipeline 3 can be controlled by setting flow valve 2. A large amount of foam generated during the concentration process pushes the hollow float 16 up, and the float valve 5 opens, so that the defoaming agent stored in the metering barrel 1 falls into the concentrated material through pipeline 3. The defoaming agent eliminates the foam, and the hollow float 16 loses support and falls, causing the float valve 5 to close.

[0029] In order to enable the float valve 5 to satisfy the function of opening the float valve 5 when the hollow float 16 rises and closing the float valve 5 when the hollow float 16 falls, the float valve 5 includes a valve body 6, a liquid inlet 17 and a liquid outlet 9 are provided on the valve body 6, a convergence hole 8 is provided between the liquid outlet 9 and the liquid inlet 17, a sealing plug 7 driven by a valve stem 10 to move is provided on the side of the convergence hole 8 close to the liquid inlet 17, the valve stem 10 is slidably connected to the valve body 6 and is driven to slide by the hollow float 16 through a transmission mechanism.

[0030] When the hollow float 16 is pushed up by the foam, the hollow float 16 drives the sealing plug 7 to move away from the focusing hole 8, the defoaming agent passes through the focusing hole 8 and is discharged from the liquid outlet 9, and the float valve 5 opens; when the foam is eliminated by the defoaming agent, the hollow float 16 loses its support and falls due to gravity, the hollow float 16 drives the sealing plug 7 to move close to the focusing hole 8, and seals the focusing hole 8 through the sealing plug 7, and the float valve 5 closes.

[0031] Specifically, the valve stem 10 passes through the convergence hole 8 . To ensure that the defoaming agent can smoothly pass through the convergence hole 8 , the diameter of the convergence hole 8 is greater than the diameter of the valve stem 10 .

[0032] In order to improve the sealing effect, the valve stem 10 is provided with a sealing plug 7, one end of which is fixedly connected with a pressing block 18. When the float valve 5 is closed, the pressing block 18 presses the sealing plug 7 at the convergence hole 8 to prevent liquid leakage at the convergence hole 8.

[0033] In some embodiments, the transmission mechanism includes a transmission rod 12 and a float rod 13, the middle section of the transmission rod 12 is rotatably connected to the valve body 6, one end of the transmission rod 12 is hinged to the valve stem 10, and the other end of the transmission rod 12 is fixedly connected to the float rod 13, and the hollow float 16 is fixedly connected to the end of the float rod 13 away from the transmission rod 12.

[0034] When the hollow float 16 rises, the float rod 13 and the transmission rod 12 drive the valve stem 10 to drive the sealing plug 7 away from the focusing hole 8. When the hollow float 16 descends, the float rod 13 and the transmission rod 12 drive the valve stem 10 to drive the sealing plug 7 close to the focusing hole 8. At the same time, a longer float rod 13 is used as a power arm to obtain power sufficient to drive the valve stem 10 to move back and forth.

[0035] Specifically, a strip hole 11 is provided at the hinged portion between the transmission rod 12 and the valve stem 10. By providing the strip hole 11, the relative displacement between the transmission rod 12 and the end of the valve stem 10 can be satisfied when the transmission rod 12 rotates.

[0036] In some embodiments, in order to facilitate the adjustment of the relative height of the hollow float 16, the float rod 13 is connected to the transmission rod 12 through the U-shaped block 15, and the transmission rod 12 is plugged into the U-shaped block 15 and fixed by the locking bolt 14. When adjusting, the locking bolt 14 is loosened, the float rod 13 is rotated relative to the transmission rod 12 to a pre-adjusted height, and then the locking bolt 14 is tightened to make the U-shaped block 15 produce elastic deformation to clamp the transmission rod 12.

[0037] Preferably, the inner side of the U-shaped block 15 is provided with anti-skid grooves, and by providing the anti-skid grooves, the friction between the transmission rod 12 and the float rod 13 is increased, thereby preventing the float rod 13 and the transmission rod 12 from rotating relative to each other.

[0038] Working principle: When in use, the device is installed on the concentration equipment, and the initial position of the hollow float 16 is above the liquid level. Defoaming agent is added to the metering barrel 1, and the flow rate of the pipeline 3 is adjusted through the flow valve 2. The manual valve 4 is opened. When a large amount of foam is generated during the concentration process, the foam pushes the hollow float 16. The hollow float 16 pushes the strip hole 11 to slide along the valve body 6 through the float rod 13 and the transmission rod 12, driving the sealing plug 7 away from the convergence hole 8. At this time, the float valve 5 is opened, and the defoaming agent in the metering barrel 1 flows to the concentration equipment through the pipeline 3. The foam is eliminated by the defoaming agent to avoid overflow. The hollow float 16 loses the foam support and falls, thereby driving the sealing plug 7 to approach the convergence hole 8 to seal it. At this time, the float valve 5 is closed, thereby realizing the automatic addition of defoaming agent.

[0039] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
