Description

Technical Field

[0001] This utility model relates to a device for indicating and alarming the material level in a dust collection silo, belonging to the technical field of dust collection silo equipment. Background Technology

[0002] Dust silos are critical equipment for storing dust, and accurate monitoring of their levels is essential. Currently used dust silo level monitoring devices have several problems. For example, some devices using mechanical contact detection methods are prone to frequent malfunctions due to dust erosion and mechanical wear, resulting in high maintenance costs. Other devices employ complex electronic sensing principles, which are not only expensive but also lack stability in high-dust-concentration and complex operating environments, easily leading to false alarms or missed alarms. This results in the silo being full without timely notification to staff for ash release, causing dust overflow, polluting the production environment, affecting the normal operation of production equipment, and potentially even posing safety hazards. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a material level indicator and alarm device for a dust removal ash silo. This indicator and alarm device can provide a full silo signal when the dust removal ash silo is full, reminding employees to release ash in time to prevent the ash silo from overflowing. It has the advantages of easy implementation and installation, stable status and rapid response, and can effectively ensure the normal operation of the dust removal ash silo.

[0004] The technical solution to the above technical problem is:

[0005] A material level indicator and alarm device for a dust collector hopper includes a material elastic push plate, a movable trigger plate, a compression spring, a proximity switch fixing plate, a connecting rod, a proximity switch, a relay, and an alarm. The upper side wall of the dust collector hopper has a monitoring hole. The material elastic push plate is an elastic rubber plate, and its edge is fixed around the monitoring hole to seal it. A movable trigger plate is fixed to the outer wall of the material elastic push plate. One end of the compression spring is fixedly connected to the movable trigger plate, and the other end is connected to the proximity switch fixing plate. The proximity switch fixing plate is parallel to the outer wall of the dust collector hopper. The lower end of the proximity switch fixing plate is fixed to the outer wall of the dust collector hopper via the connecting rod. The proximity switch is fixed to the proximity switch fixing plate, and its front end is opposite to the movable trigger plate fixed to the outside of the material elastic push plate. The proximity switch is connected to the relay coil via a control line, and the relay is connected to the alarm.

[0006] The material level indicator alarm device of the above-mentioned dust removal ash silo has a circular monitoring hole on the side wall of the dust removal ash silo, and a circular elastic rubber plate for the material elastic push plate. The circular elastic rubber plate of the material elastic push plate has an arc, and the convex direction of the arc faces the inner cavity of the dust removal ash silo. The circumference of the material elastic push plate is fixedly connected to the circumference of the monitoring hole of the dust removal ash silo by multiple bolts.

[0007] In the aforementioned dust removal ash silo level indicator alarm device, the movable trigger plate and the proximity switch fixing plate are identical circular plates. One end of each of the two compression springs is fixedly connected to both sides of the movable trigger plate, and the other end of each of the two compression springs is fixedly connected to both sides of the proximity switch fixing plate. The proximity switch fixing plate has a circular hole in the center, and the proximity switch is fixed to the center of the proximity switch fixing plate through the circular hole.

[0008] The material level indicator alarm device of the above-mentioned dust removal ash silo has an L-shaped connecting rod. The two short rods of the L-shaped rod are located in a vertical position and a horizontal position, respectively. The vertical short rod is connected to the lower end of the proximity switch fixing plate and is parallel to the plate surface of the proximity switch fixing plate. The outer end of the horizontal short rod is vertically fixedly connected to the outer wall of the dust removal ash silo.

[0009] The beneficial effects of this utility model are:

[0010] The dust collection hopper of this invention has a monitoring hole on the upper side wall. A material elastic push plate is installed on the monitoring hole. When the material reaches the position of the material elastic push plate, it can push the material elastic push plate outward, and the elastic rubber plate of the material elastic push plate can bulge outward. The moving trigger piece moves outward with the material elastic push plate to the outside of the dust collection hopper. When the moving trigger piece moves outward, it can trigger a proximity switch. The proximity switch will trigger an alarm through a relay and an alarm. When the material has not reached the position of the material elastic push plate, the compression spring can push the material elastic push plate to the inside of the dust collection hopper and maintain its original position.

[0011] This utility model has a simple structure, is easy to use and manufacture, and greatly reduces procurement and maintenance costs. It adopts a mechanical non-contact triggering principle, which is not affected by complex working conditions such as dust concentration and humidity. It is not prone to false alarms or missed alarms, and can reliably monitor the full status of the ash silo. At the same time, the installation position is flexible, which facilitates daily inspection, maintenance and replacement of parts, and will not interfere with the normal operation of the dust removal ash silo.

Proximity switch fixing plate; 7. Connecting rod; 8. Proximity switch; 9. Relay; 10. Alarm; 11. Material. Detailed Implementation

[0015] This utility model consists of a material elastic push plate 3, a moving trigger plate 4, a compression spring 5, a proximity switch fixing plate 6, a connecting rod 7, a proximity switch 8, a relay 9, and an alarm 10.

[0016] Figure 1 As shown, in order to monitor the material level in the dust removal silo 1, a monitoring hole 2 is provided on the upper side wall of the dust removal silo 1. This utility model is installed outside the monitoring hole 2 on the upper part of the dust removal silo 1.

[0017] Figure 1 , 2 The monitor hole 2 on the side wall of the dust collector hopper 1 is circular, and the material elastic push plate 3 is a circular elastic rubber plate with an arc. The convex direction of the arc faces the inner cavity of the dust collector hopper 1. The circumference of the material elastic push plate 3 is fixedly connected to the circumference of the monitor hole 2 of the dust collector hopper 1 by multiple bolts, thus sealing the monitor hole 2. When the material 11 reaches the position of the material elastic push plate 3, due to the concave and convex shape of the material elastic push plate 3, the material can squeeze the material elastic push plate 3 outward, and the elastic rubber plate of the material elastic push plate 3 can bulge outward. The elastic rubber plate of the material elastic push plate 3 can sense the change in the material level in the dust collector hopper 1, and its tension changes with the increase of the material 11.

[0018] Figure 1 , 2 The display shows that a movable trigger plate 4 is fixed on the outer wall of the material elastic push plate 3. The movable trigger plate 4 is a circular plate. When the material elastic push plate 3 protrudes outward, the movable trigger plate 4 moves outward accordingly.

[0019] Figure 1 , 2 The display shows that one end of each of the two compression springs 5 ​​is fixedly connected to both sides of the movable trigger plate 4, and the other end of each of the two compression springs is fixedly connected to both sides of the proximity switch fixing plate 6. The proximity switch fixing plate 6 is a circular plate, parallel to the outer wall of the dust collection hopper 1, and the lower end of the proximity switch fixing plate 6 is fixed to the outer wall of the dust collection hopper 1 via a connecting rod 7.

[0020] Figure 1 , 2 The display shows that the connecting rod 7 is an L-shaped rod, with the two short rods of the L-shaped rod located in the vertical and horizontal positions respectively. The vertical short rod is connected to the lower end of the proximity switch fixing plate 6 and is parallel to the plate surface of the proximity switch fixing plate 6. The outer end of the horizontal short rod is vertically fixed to the outer wall of the dust collector 1.

[0021] Figure 1 , 2The display shows that the proximity switch mounting plate 6 has a circular hole in the center, and the proximity switch 8 is fixed to the center of the proximity switch mounting plate 6 through the circular hole. The front end of the proximity switch 8 is opposite to the movable trigger piece 4 fixed on the outside of the material elastic push plate 3. The proximity switch 8 is connected to the coil of the relay 9 through the control line. After the relay 9 opens and closes, it triggers the alarm 10 to provide an alarm prompt.

[0022] The usage process of this utility model is as follows:

[0023] When material 11 (dust collector ash) 11 reaches the position of the material elastic push plate 3, due to the concave and convex shape of the material elastic push plate 3, material 11 can squeeze the material elastic push plate 3 outward, causing the elastic rubber plate of the material elastic push plate 3 to bulge outward. At this time, the movable trigger piece 4 fixed on the material elastic push plate 3 will be displaced accordingly. When the movable trigger piece 4 approaches the proximity switch 8 fixed at the front end of the proximity switch fixing plate 6, the proximity switch 8 senses the movable trigger piece 4 and closes, generating an electrical signal to trigger the relay 9 to engage. The relay 9 issues a full hopper alarm through the alarm 10, reminding the staff to empty the dust collector ash hopper 1.

[0024] When the material level 11 (dust collector ash) is lower than the material elastic push plate 3, the compression spring 5 will squeeze the material elastic push plate 3 to return to normal. The moving trigger plate 4 on the material elastic push plate 3 will move away from the proximity switch 8. The proximity switch 8 will disconnect because it does not sense the moving trigger plate 4, the corresponding relay 9 will be released, and the alarm signal will disappear.

[0025] An embodiment of this utility model is as follows:

[0026] The material elastic push plate 3 has a diameter of 250mm, a thickness of 8mm, and a distance of 30mm between its protruding outer end and the plane.

[0027] The diameter of the movable trigger piece 4 is 150mm and the thickness is 3mm;

[0028] The compression spring 5 has a length of 250mm, a mean diameter of 10mm, and a wire diameter of 1.2mm.

[0029] The diameter of the proximity switch mounting plate 6 is 200mm and the thickness is 5mm;

[0030] The connecting rod 7 has a diameter of 15mm and a length of 250mm (L-shaped rod, 150mm horizontal section and 100mm vertical section) made of 45# steel;

[0031] The proximity switch 8 is model Omron E2E-X5ME1 (detection distance 10-15mm).

[0032] The model of relay 9 is Omron MY4N 220V;

[0033] The model of alarm 10 is SND-TG-220V, an audible and visual alarm.
