Description
Technical Field
The utility model relates to a liquid level detection technical field especially relates to a retrieve filter liquid level detection device.
Background
PTA is pure terephthalic acid, which is white crystal or powder at normal temperature, low toxicity and easy combustion. The mother liquor needs to be recycled and filtered in the manufacturing process. In the prior art, a tuning fork liquid level switch is usually installed on the top of the recovery filter to detect the liquid level in the recovery filter, and corresponding instructions are made according to the height of the liquid level. However, in the actual use process, the program is stopped in the middle of execution, so that the normal filtration process cannot be completed. In order not to affect the continuous production of the equipment, the mother liquor in the recovery filter is led away from the bypass. So that a large amount of mother liquor enters the sewage tank, and finally, the wastewater treatment is difficult.
The reason for this is that the tuning fork is attached with the slurry. The regular alkali washing of the device does not wash away the slurry attached to the tuning fork, thereby causing false alarm information of high and low liquid level.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a retrieve filter liquid level detection device has and washs the thick liquids on the tuning fork, reduces the liquid level and reports high and the advantage of low newspaper.
In order to realize the purpose, the utility model discloses a technical scheme is: a liquid level detection device for a recovery filter comprises a recovery filter body, a mounting pipe and a tuning fork switch, wherein the mounting pipe and the tuning fork switch are arranged at the top of the recovery filter body;
the lateral wall that washes the ring runs through and has seted up the feed liquor hole, the lateral wall that washes the ring still is provided with the connector that is used for with the pipe connection, the feed liquor hole is located the axis position department of connector.
Preferably, the two liquid inlet holes are coaxially arranged, and the connectors are correspondingly arranged at the two liquid inlet holes.
Preferably, rubber gaskets are respectively clamped between the flushing ring and the upper flange plate and between the flushing ring and the lower flange plate.
Preferably, the flush ring is made of stainless steel.
Compared with the prior art, the utility model has the advantages of:
the structure is simple, and the transformation process is convenient;
secondly, arranging two liquid inlet holes to enable all surfaces of the tuning fork switch tuning fork part to be washed by alkali liquor;
and thirdly, the flushing ring is made of stainless steel, so that the alkali resistance is better, and the service life of the flushing ring is longer.
Drawings
FIG. 1 is a schematic view of the overall structure of the present embodiment;
fig. 2 is a schematic structural view of the flushing ring of the present embodiment.
In the figure: 1. recovering the filter body; 2. installing a pipe; 3. a tuning fork switch; 4. a lower flange plate; 5. an upper flange plate; 6. flushing the ring; 61. a connector; 62. a liquid inlet hole; 7. a rubber gasket.
Detailed Description
The present invention will be further explained below.
Example (b):
as shown in figure 1, the liquid level detection device of the recovery filter comprises a recovery filter body 1, a mounting pipe 2 arranged at the top of the recovery filter body 1, a tuning fork switch 3 and a flushing ring 6. The lower extreme of installation pipe 2 sets up with the top intercommunication of retrieving filter body 1, and the top welding of installation pipe 2 is provided with lower flange 4. An upper flange 5 is arranged on the tuning fork switch 3.
As shown in fig. 1, a flushing ring 6 made of stainless steel material is sandwiched between the upper flange 5 and the lower flange 4, rubber gaskets 7 are disposed on both upper and lower sides of the flushing ring 6, and the upper flange 5 is connected to the lower flange 4 by bolts. The impact ring made of stainless steel has better alkali resistance, so that the service life of the flushing ring 6 is longer, and the frequency of replacing the flushing ring 6 is reduced.
As shown in fig. 1 and 2, two liquid inlet holes 62 are formed through the outer side wall of the flushing ring 6, and the two liquid inlet holes 62 are coaxially arranged. So that all surfaces of the tuning fork part of the tuning fork switch 3 can be washed by lye. The outer side wall of the flushing ring 6 is further provided with two connectors 61 for connection with pipes, and the liquid inlet hole 62 is located at the axial position of the connectors 61.
During installation, place a rubber packing ring 7 on lower ring flange 4, will wash ring 6 and place on rubber packing ring 7 afterwards to be used for to wash the inside pipeline and the connector 61 of pouring into the buck of ring 6, the connected mode is threaded connection in this embodiment, and the junction twines many circles of raw rubber belt, takes place in order to prevent the condition of weeping. Then another rubber pad is placed on the upper surface of the washing ring 6, then the tuning fork part of the tuning fork switch 3 is aligned with the inner ring of the washing ring 6 and inserted, so that the lower surface of the upper flange 5 is in contact with the rubber gasket 7, and at the moment, the tuning fork position of the tuning fork switch 3 is positioned below the liquid inlet hole 62, so that alkali liquor entering from the liquid inlet hole 62 can be poured on the tuning fork part conveniently, and the slurry attached to the tuning fork part can be cleaned. The operator then adjusts the position of the upper flange 5 to align it with the lower flange 4 and adjusts the position of the rinse ring 6 so that the pipe connected to the rinse ring 6 does not interfere with the bolts connecting the upper flange 5 to the lower flange 4. And finally, an operator can complete the whole installation process by connecting the upper flange 5 and the lower flange 4 through bolts. The rubber gasket 7 seals the gap between the flushing ring 6 and the lower flange plate 4, and prevents the alkali liquor from leaking from the joint of the flushing ring 6 and the lower flange plate 4 in the process of filling the alkali liquor. The rubber gasket 7 protects the contact surface of the wash ring 6 with the upper flange 5 and prevents a rigid contact between the upper flange 5 and the wash ring 6.
After the installation is finished, an operator only needs to convey alkali liquor into the pipeline at regular time to independently perform alkali washing on the tuning fork part of the tuning fork switch 3. Therefore, false alarm information of high and low liquid level reports is reduced.
The principle and the implementation of the present invention are explained herein by using specific examples, and the above description of the embodiments is only used to help understand the method and the core idea of the present invention; while the invention has been described in terms of specific embodiments and applications, it will be apparent to those skilled in the art that numerous variations and modifications can be made without departing from the spirit and scope of the invention as defined in the appended claims.
