Technical Field

[0001] The utility model relates to the technical field of foundry sand production, in particular to a quartz sand foundry sand bucket elevator for fracturing. Background Art

[0002] Fracturing quartz sand is a filling material used in fracturing operations, commonly found in the field of oil and gas extraction. During the fracturing process, high-pressure liquid (usually water) is injected into the rock layer to create cracks and increase permeability, and fracturing quartz sand is used to fill these cracks to maintain pressure and stabilize the rock layer. In order to effectively lift granular materials such as quartz sand, cast sand bucket elevators are often used in fracturing operations. This equipment can improve production efficiency, reduce labor costs, ensure continuous feeding, and adapt to various harsh environmental conditions, so it is widely used in fracturing operations.

[0003] Photoelectric sensors are used to determine the operating status and speed of the elevator, so that the material can avoid product quality problems and blockage at the bottom. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a quartz sand casting sand bucket elevator for fracturing, aiming to improve the device to realize remote monitoring of the operating status, reduce the occurrence of production line shutdowns due to faults, and reduce the occurrence of waste; and through remote monitoring communication with other equipment, it also reduces the characteristics of personnel settings.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a quartz sand casting sand bucket elevator for fracturing, comprising an upper end mechanism, wherein the upper end mechanism is connected with an intermediate section mechanism, a lower end mechanism and a transmission mechanism;

[0006] The upper end mechanism includes a dust collecting hood at the upper end of the bucket elevator; a dust outlet for connecting the dust removal duct; a main driving wheel, which is wrapped with rubber with a thickness of 1 cm to increase the service life; a feeding port; a bearing bracket assembly for fixing the driving wheel; a photoelectric sensor for monitoring the operating status, and a convex point required for detecting the photoelectric sensor; a driving device including a driving reducer, which uses a JZQ350 cylindrical gear reducer, a roller chain coupling for connecting the main driving wheel and the driving reducer, and a driving device for providing power to the reducer, and a pulley 2 is connected to a pulley 1 with a B-type V-belt, and the reducer is driven to rotate under the action of the driving device and then drives the driving wheel to rotate.

[0007] Furthermore, the lower end mechanism includes a lower tail wheel, which adopts a "basket-type" design, and its design can reduce its weight. At the same time, when the plate belt rotates, the material will not be introduced between the plate belt and the wheel, causing the plate belt to deviate; two bearing bracket assemblies for fixing the lower tail wheel; two photoelectric sensors for monitoring the operating status, and two detection convex points required by the photoelectric sensor.

[0008] Furthermore, a second feeding port is provided on one side of the lower end mechanism.

[0009] Furthermore, the conveying mechanism includes a conveying belt and a nylon hopper.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1 - Figure 5 The utility model provides an embodiment: a quartz sand casting sand bucket elevator for fracturing, including an upper end mechanism 18, the upper end mechanism 18 is connected with an intermediate section mechanism 25, a lower end mechanism 19 and a transmission mechanism 20; the upper end mechanism 18 includes a dust collecting cover 1 at the upper end of the bucket elevator; a dust outlet 2 for connecting the dust removal pipeline; a main driving wheel 3, the main driving wheel 3 is wrapped with a rubber 10 with a thickness of 1 cm, which can increase the service life; a feed port 6; a bearing bracket assembly 11 for fixing the driving wheel; a photoelectric sensor 13 for monitoring the operating status, and a detection convex point 12 required for the photoelectric sensor 13; a driving device 17 includes a driving reducer 15, the reducer uses a JZQ350 cylindrical gear reducer, and is used to connect the roller chain coupling 14 between the main driving wheel 3 and the driving reducer 15, to provide the reducer The driving device 17 for power supply, the pulley 21 and the pulley 1 16 are connected by a B-type V-belt, and the reducer 15 is driven to rotate under the action of the driving device 17, and then the driving wheel is driven to rotate; the lower end mechanism 19 includes a lower tail wheel 9, and the lower tail wheel 9 adopts a "flower basket" design, which can reduce its weight, and at the same time, when the plate belt rotates, the material will not be derived between the plate belt and the wheel, causing the plate belt to deviate; a bearing bracket assembly 24 for fixing the lower tail wheel 9; a photoelectric sensor 22 for monitoring the operating status, and a detection convex point 23 required for the photoelectric sensor 22; a discharge port 28 is set on one side of the lower end mechanism 19; the conveying mechanism 20 includes a conveying plate belt 7 and a nylon hopper 5; the intermediate section mechanism 25 is made according to the actual situation, and is used to connect the upper end mechanism 18 and the lower end mechanism 19 to form a whole;

[0023] Specifically, the photoelectric sensor 22 of the lower tail wheel 9 and the photoelectric sensor 13 of the main drive wheel 3 are used in series, and then connected to the control system in the control room with a special cable. If one of the sensors cannot detect the running signal, the tachometer in the electric control cabinet will take corresponding action, stop the operation of the front-end process equipment and issue an audible and visual alarm. At the same time, the electrical control system will make a judgment, record the time when the fault occurs, the time when the fault is relieved, and which device specifically fails. When selecting the photoelectric sensor 13 and the photoelectric sensor 22, first select the NPN type 3-wire DC 24V. The purpose of selecting DC 24V is that it has a high safety factor and will not cause leakage and electric shock. Secondly, it is also necessary to select a bump detection function, and the detection distance needs to be 1 cm, so that it can be reasonably installed according to the on-site conditions. When installing the photoelectric sensor 13 and the photoelectric sensor 22, first weld a 1 cm high protrusion on the shaft of the main drive wheel 3 and the lower tail wheel 9, and the top area must meet 1 square centimeter. Secondly, the photoelectric sensor 13 and the photoelectric sensor 2 22 are fixed with a bracket on the opposite side of the protrusion. The distance should not exceed 1 cm, but should not be less than 5 mm. If the distance is too high, the signal cannot be detected. If the distance is too low, the bucket elevator shaft will swing during operation, causing damage to the photoelectric sensor 13 and the photoelectric sensor 2 22. The drive device 17 to which the upper end mechanism 18 belongs adopts a JZQ350 cylindrical gear reducer. The drive reducer 15 has the characteristics of large torque, simple maintenance, and low maintenance cost. The coupling is installed using a roller chain coupling 14, which has a long service life and is easy to maintain. The drive motor uses a 4-stage 4-kilowatt drive reducer 15 to rotate through a pulley and a V-belt. The pulleys all use the B-type 3-groove form. Since the main drive wheel 3 is made of steel, the conveyor belt 7 will directly contact and rub, which will shorten the service life. Now it is wrapped with a rubber 10 with a thickness of 1 cm to increase the service life of the conveyor belt 7. The lower part of the lower end mechanism 19 adopts an arc design, which can reduce the accumulation of materials and avoid the mixing of materials due to too many types, which may lead to product quality problems. At the same time, when there are too many materials, the hopper is easily blocked at the bottom of the elevator. The conveying mechanism 20 uses a conveyor belt 7 with a thickness of 8 mm, a steel wire inside, and a width of 400 mm. The hopper uses an appropriate nylon hopper 5 according to the hourly production volume. The nylon hopper 5 has the characteristics of impact resistance, corrosion resistance, high strength, light weight, and smoothness. The nylon hopper 5 and the conveyor belt 7 are installed with special bucket nails. The main drive wheel 3 and the lower tail wheel 9 bearing assembly adopts the P310 model. The P series bearing has the advantages of simple maintenance and convenient disassembly and assembly. This device must have a dust removal pipeline, which must be connected to the dust collector.

[0024] Working principle: By starting the driving reducer 15, the main driving wheel 3 and the roller chain coupling 14 on one side are driven to transmit, and the main driving wheel 3 and the lower tail 9 cooperate to drive the V-belt to rotate synchronously. When the V-belt moves, the conveyor belt 7 is driven by the V-belt to transmit, and at the same time, the photoelectric sensor 13 and the photoelectric sensor 2 22 cooperate to detect the information of the material passing, thereby achieving the effect of transmitting specific values.

[0025] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
