Abstract
The utility model discloses an asphalt tank liquid level detection and alarm device. The asphalt tank liquid level detection and alarm device comprises a floating ball or a buoy which is arranged in an asphalt tank and can fluctuate up and down along with the liquid level, wherein the floating ball or the buoy is fixedly connected to a rotatable shaft which penetrates through a seal head of the asphalt tank and is arranged in the tank through a plumbing bar; the rotating shaft extends out of the tank through a sealing shaft sleeve which is arranged on the seal head of the asphalt tank and is connected with a pointer; a liquid level dial plate which indicates three positions, namely an extremely high liquid level, a closed upper combustor on a low liquid level and an extremely low liquid level, corresponds to the pointer; three proximity switches which are respectively communicated with an alarm detector are respectively arranged on the outer side of the tail end of the pointer which corresponds to three positions, namely the extremely high liquid level, the closed upper combustor on the low liquid level and the extremely low liquid level; and induction pieces matched with the proximity switches are arranged at the tail end of the pointer. The asphalt tank liquid level detection and alarm device has the characteristics that manual monitoring is not required during operation, the labor resources are saved, potential safety hazard is reduced, and the automation degree is high, and the control is accurate.
Description
Technical field
The utility model relates to a kind of asphalt tank Level Detection and warning device of modified asphalt macadam synchronous chip sealer.
Background technology
The modified asphalt macadam synchronous chip sealer is that rubble that meets certain technical requirements and modified bitumen are sprinkled upon on the road surface shop synchronously, rolls through natural traffic bound or pneumatic-tired rollers and forms individual layer asphalt macadam wearing course.Asphalt coating makes the road surface have good water-impervious performance and cling property after punishing through synchronous surface dressing, can effectively cure diseases such as oil-poor, loose, the slight check crack in road surface, rut, depression, and prolonged about 10 years the service life of asphalt coating.
Present modified asphalt macadam synchronous chip sealer is fire tube and the phenomenon of fire tube dry combustion method or the too high or too low phenomenon of bitumen level liquid level in jar on causing on the ubiquity bitumen level is lower than in construction medium pitch jar; This just need manual observation in construction, does not have warning device.Understand following shortcoming like this: 1. need manual monitoring, lost labor's resource when working; 2. go up air in the fire tube dry combustion method jar, thereby a jar internal pressure increases and causes potential safety hazard.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that prior art exists; And provide a kind of can the realization that liquid level in the asphalt tank is monitored, and asphalt tank Level Detection and the warning device according to circumstances cutting off upper burner section or carry out the too high or too low warning of liquid level.
The purpose of the utility model is accomplished through following technical scheme; It comprises that one places in the pitch tank body ball float or the floating drum that can just rise and fall with liquid level; Described ball float or floating drum are connected in one through a plumbing bar and pass the asphalt tank end socket and place in the tank body in the rotating rotating shaft; Described rotating shaft is stretched out outside tank body through a sealing axle sleeve of installing on the asphalt tank end socket and the pointer that links to each other; Being provided with one corresponding to said pointer indicates at least the liquid level dial plate that liquid level is too high, the low upper burner section of liquid level is closed, liquid level is crossed low three positions is arranged; The pointer tail end outer fix that the low upper burner section of, liquid level too high corresponding to said liquid level is closed, liquid level is crossed low three positions be respectively arranged with each one be communicated with Alarm Detector near switch, and the pointer tail end be provided with near the supporting sensing chip of switch.
Described three near switch be installed in one place with pointer rotate round dot be the semicircular at center near on the switch mount pad, this semicircular radius near the switch mount pad rotates the distance of round dot to the pointer tail end greater than said pointer.
Described pointer is fixed on the end of rotating shaft, and the external side of asphalt tank that is positioned at sealing shroud in the rotating shaft disposes packing ring and nut, and at the inboard configuration of pitch tank body seal ring.
Described rotating shaft places the end in the tank body to be provided with the support channel-section steel, two gussets about also being connected with the plumbing bar joint in the rotating shaft.
The utility model and conventional artificial are observed relatively has following several advantage: 1. do not need manual monitoring when working, practice thrift manual resource; 2. prevent air in the fire tube dry combustion method jar, thereby a jar internal pressure increases and causes potential safety hazard.3. degree of automation is high, and control accurately.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is that the A of Fig. 1 is to view.
Fig. 3 is the described circuit system schematic diagram of the utility model.
The specific embodiment
To combine below accompanying drawing to the utility model make detailed introduction: Fig. 1, shown in 2; The utility model comprises that one places in the pitch tank body ball float 2 or the floating drum that can just rise and fall with liquid level; Described ball float 2 or floating drum are connected in one through a plumbing bar 3 and pass asphalt tank sidewall 1 and place in the tank body in the rotating rotating shaft 6; Described rotating shaft 6 is stretched out outside tank body through a sealing axle sleeve 7 of installing on the asphalt tank sidewall and the pointer 11 that links to each other; Corresponding to said pointer 11 be provided with one indicate at least have that liquid level is too high 15, the low upper burner section of liquid level closes 16, liquid level is crossed low 17 3 positions liquid level dial plate 12; The pointer tail end outer fix that the low upper burner section of, liquid level too high 15 corresponding to said liquid level closes 16, liquid level is crossed low 17 3 positions be respectively arranged with each one be communicated with Alarm Detector near switch 14, and the pointer tail end be provided with near the supporting sensing chip of switch.
Shown in Fig. 2 three near switch 14 be installed in one place with pointer rotate round dot be the semicircular at center near on the switch mount pad 13, this semicircular radius near switch mount pad 13 rotates the distance of round dot to the pointer tail end greater than said pointer.
Described pointer 11 is fixed on the end of rotating shaft 6, and the external side of asphalt tank that is positioned at sealing axle sleeve 7 in the rotating shaft 6 disposes packing ring 9 and nut 10, and at the inboard configuration of pitch tank body seal ring 8.
Described rotating shaft 6 places the end in the tank body to be provided with and supports channel-section steel 5, two gussets 4 about also being connected with plumbing bar 3 joints in the rotating shaft 6.
Shown in Figure 3; The working process of the utility model is: install near switch 14 at liquid level pointer 11 tail ends of asphalt tank; Identify respectively that the asphalt tank liquid level is too high, the asphalt tank liquid level is lower than upper burner section, upper burner section is closed, the asphalt tank liquid level is crossed low three positions.In the process of construction, the liquid level in the asphalt tank is along with the sprinkling of pitch reduces gradually, if the asphalt tank liquid level is lower than upper burner section (going up fire tube); Near the sensing chip of inductive switching to the pointer tail end; Upper burner section is closed, thereby realizes that the asphalt tank liquid level is lower than upper burner section, the effect that upper burner section is closed; Otherwise, upper burner operation; The asphalt tank liquid level is too high, reports to the police and stops filling, otherwise continue filling; The asphalt tank liquid level is low excessively, reports to the police and stops construction, otherwise works on.
