Description

Technical Field

[0001] The utility model relates to the technical field of pulp molding, in particular to a device for detecting liquid level. Background Art

[0002] Pulp molded products are formed in a mold forming machine with a filter screen by adding a certain concentration of pulp and appropriate chemical additives. In the mold forming machine, the fiber pulp is evenly distributed on the mold surface by vacuum or pressure, thereby forming a wet paper mold with a predetermined geometric shape and size. After further dehydration, demoulding, drying and finishing, a paper product with a specific geometric cavity structure and a certain compressive buffering capacity is finally formed. The pulp molding machine can automatically complete the process of grouting, suction filtration, cold pressing and shaping, heat transfer, drying, demoulding, etc. Among them, the grouting and suction filtration process requires the use of a pulp box and a pulp return pool. This process requires the installation of a liquid level detector to detect the liquid level, so as to accurately control the pulp inlet and outlet. However, most of the liquid level detection devices on the market need to contact the liquid to detect, which is easy to be damaged by short circuit and difficult to repair. Utility Model Content

[0003] The technical problem to be solved by the utility model is that, in view of the above-mentioned defects of the prior art, a device for detecting the height of a liquid is provided. By installing the detector on the side of a plexiglass connecting tube, liquid is prevented from contacting the detector, thereby reducing the risk of damage, reducing the difficulty of maintenance, and facilitating later inspection and maintenance.

[0004] In order to solve the above technical problems, the technical solution of the utility model is:

[0005] A device for detecting liquid level, comprising a first device mounting interface, a second device mounting interface, an organic glass connecting tube, a hollow steel ball and a detector, wherein the organic glass connecting tube is respectively connected to the first device mounting interface and the second device mounting interface, the detector is mounted on the side of the organic glass connecting tube, the hollow steel ball is arranged in the organic glass connecting tube, and the first device mounting interface and the second device mounting interface are sequentially mounted on the outside of a quantitative barrel from top to bottom.

[0006] Preferably, the detector comprises a housing, a liquid level sensor and a PLC controller, the liquid level sensor and the PLC controller are both installed in the housing, and the liquid level sensor is electrically connected to the PLC controller.

[0007] Preferably, the liquid level sensor includes a first liquid level sensor and a second liquid level sensor, and both the first liquid level sensor and the second liquid level sensor are electrically connected to the PLC controller.

[0008] Preferably, a snap-fit ​​buckle is provided on the side of the shell, and the snap-fit ​​buckle is sleeved on the outer side of the organic glass connecting tube.

[0009] Preferably, the first device installation interface and the second device installation interface are both connected to the interior of the quantitative barrel.

[0010] Preferably, the PLC controller is provided with an upper limit feedback port and a lower limit feedback port, and the upper limit feedback port and the lower limit feedback port are electrically connected to the first liquid level sensor and the second liquid level sensor respectively.

[0011] By adopting the above technical scheme, the utility model provides a device for detecting the height of liquid level, which has the following beneficial effects: the plexiglass connecting tube in the device for detecting the height of liquid level is respectively connected with the first device installation interface and the second device installation interface, the detector is installed on the side of the plexiglass connecting tube, and the hollow steel ball is arranged in the plexiglass connecting tube. The first device installation interface and the second device installation interface are sequentially installed on the outside of the quantitative barrel from top to bottom. When liquid is added to the quantitative barrel, the liquid flows into the plexiglass connecting tube from the second device installation interface. At this time, after the hollow steel ball rises to the position of the detector through buoyancy, the detector detects the height of the hollow steel ball and feeds back a signal to the control system, thereby realizing liquid level detection. By installing the detector on the side of the plexiglass connecting tube, liquid is prevented from contacting the detector, thereby reducing the risk of damage, reducing the difficulty of maintenance, and facilitating later inspection and maintenance.

[0020] like Figure 1-4 As shown, the liquid level detection device includes a first device installation interface 1, a second device installation interface 2, an organic glass connecting tube 3, a hollow steel ball 4 and a detector 5. The organic glass connecting tube 3 is connected to the first device installation interface 1 and the second device installation interface 2 respectively. The detector 5 is installed on the side of the organic glass connecting tube 3. The hollow steel ball 4 is arranged in the organic glass connecting tube 3. The first device installation interface 1 and the second device installation interface 2 are sequentially installed on the outside of the quantitative barrel 8 from top to bottom. It can be understood that the first device installation interface 1 and the second device installation interface 2 can both be pipe installation interfaces, etc., the organic glass connecting tube 3 can be a universal organic glass tube, etc., and the hollow steel ball 4 is a hollow structure so as to float on the liquid surface.

[0021] Specifically, the detector 5 includes a shell 6, a liquid level sensor and a PLC controller K1, the liquid level sensor and the PLC controller K1 are both installed in the shell 6, and the liquid level sensor is electrically connected to the PLC controller K1; the liquid level sensor includes a first liquid level sensor B1 and a second liquid level sensor B2, the first liquid level sensor B1 and the second liquid level sensor B2 are both electrically connected to the PLC controller K1; a snap buckle 7 is provided on the side of the shell 6, and the snap buckle 7 is sleeved on the outside of the organic glass connecting tube 3; the first device installation interface 1 and the second device installation interface 2 are both connected to the interior of the quantitative barrel 8; an upper limit feedback port X0 and a lower limit feedback port X1 are provided on the PLC controller K1, and the upper limit feedback port X0 and the lower limit feedback port X1 are electrically connected to the first liquid level sensor B1 and the second liquid level sensor B2 respectively. It can be understood that during operation, when liquid is added to the metering barrel 8, the liquid flows from the second device installation interface 2 into the plexiglass connecting tube 3. At this time, the hollow steel ball 4 rises to the position of the detector 5 through buoyancy, and the first liquid level sensor B1 and the second liquid level sensor B2 respectively feedback the liquid level information to the PLC controller through the upper limit feedback port X0 and the lower limit feedback port X1. That is to say, the detector 5 detects the height of the hollow steel ball 4 and feeds back the signal to the control system, thereby realizing liquid level detection.
