Description

Technical Field

[0001] The utility model relates to the field of material discharging, in particular to a dust-free ash discharging machine with a lifting function. Background Art

[0002] In some powder factories, such as factories that process powdery materials such as cement, lime or processed raw materials, large quantities of powders are transported by trucks to designated locations and need to be unloaded. The unloading is done by dust-free unloading machines, which can suppress dust.

[0003] However, the current dust-free dust unloader cannot automatically adjust the unloading height when adjusting the unloading height, and can only adjust the unloading height manually. The disadvantage of manually adjusting the unloading height is that the unloading point cannot be accurately controlled and cannot be automatically adjusted as the unloading height changes, which affects the unloading efficiency. Utility Model Content

[0004] (I) Purpose of the utility model

[0005] In view of this, the purpose of the utility model is to provide a dust-free ash discharger with a lifting function to achieve automatic adjustment of the discharge height.

[0006] (II) Technical solution

[0007] In order to achieve the above technical objectives, the utility model provides a dust-free dust unloading machine with a lifting function:

[0008] It includes: a fixed frame, the upper surface of which is fixed with a sealed feed port for feeding, and the lower surface of which is fixed with a sealed cloth bag for guiding the material; a hoisting motor fixed on the upper surface of the fixed frame; a winding wheel, rotatably connected to the fixed frame, and the winding wheel is linked to the output end of the hoisting motor; a steel cable, one end of which is wound on the winding wheel and the other end is fixedly connected to the sealed cloth bag, and the winding wheel controls the sealing cloth bag to adjust its height up and down by winding the steel cable to match the ash unloading operations at different heights; a pressure roller frame, rotatably connected to the upper surface of the fixed frame, and the steel cable is slidably connected to the pressure roller frame; a discharge position detection module, fixed on the upper surface of the fixed frame, and used to detect the pressure roller frame, and the hoisting motor stops working after the pressure roller frame is detected.

[0009] Preferably, a rigid expansion joint is fixed to the lower surface of the fixing frame.

[0010] Preferably, segmented frames are evenly fixed on the outer surface of the sealing cloth bag, and the steel cable passes through a plurality of segmented frames in sequence.

[0011] Preferably, a speed reduction commutator is fixed to the output end of the hoisting motor, and the hoisting motor is linked with the winding wheel via the speed reduction commutator.

[0012] Preferably, a guide wheel is fixed to the upper surface of the fixing frame, and the steel cable is slidably connected to the guide wheel.

[0013] Preferably, a negative pressure suction system is fixed on the fixing frame to extract dust from the sealed bag.

[0014] Preferably, a dust-free discharge head is fixed to the bottom of the sealed cloth bag.

[0015] Preferably, a material level detection component is mounted on the surface of the fixing frame, and the material level detection component comprises:

[0016] The material level switch is fixed on the outer surface of the fixing frame;

[0017] The blower is fixed to the outer surface of the fixing frame, and the blowing end is connected with the material level switch through the conduit;

[0018] The detection tube has two ends respectively fixed to the material level switch and the dust-free discharge head, and the material level switch is connected to the inner cavity of the dust-free discharge head through the detection tube.

[0019] It can be seen from the above technical solutions that the present application has the following beneficial effects:

[0020] 1. A sealed cloth bag is fixed on a fixed frame, and the sealed feed port is connected with the sealed cloth bag. The sealed cloth bag can be pulled up and down to adjust the height by winding the steel cable through the winding wheel, thereby controlling the discharge height.

[0021] 2. The roller frame is connected by rotating on the fixed frame, the roller frame is placed on the steel cable, and a discharge position detection module is installed on the side of the roller frame to detect the position of the roller frame. When the dust-free discharge head does not touch the discharge point, the dust-free discharge head sags due to its own weight, so that the sealing bag is stretched with the steel cable due to its own weight, and the steel cable can lift the roller frame away from the discharge position detection module. On the contrary, when the dust-free discharge head touches the discharge point, the discharge point provides support for the dust-free discharge head. At this time, the sealing bag will shrink, the steel cable is in a non-stretched state, and the height of the roller frame will drop to the same horizontal line as the discharge position detection module. The discharge position detection module detects the roller frame, and the winch motor can stop working to realize automatic adjustment of the discharge height. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, and use. It should be understood that in all of these figures, the same or similar reference numerals indicate the same or similar parts and features. The various drawings only schematically represent the concepts and principles of the embodiments of the present disclosure, and do not necessarily show the specific dimensions and proportions of the various embodiments of the present disclosure. Specific parts in specific drawings may be exaggerated to illustrate the relevant details or structures of the embodiments of the present disclosure.

[0028] Embodiment 1

[0029] See also Figure 1 and Figure 2 As shown, the dust-free dust unloading machine with lifting function described in this embodiment includes a fixed frame 1, a sealed feed port 2, a rigid expansion joint 3, a sealed cloth bag 4, an electric hoisting assembly, a negative pressure suction system 7 and a dust-free unloading head 8. The sealed feed port 2 is fixed to the upper surface of the fixed frame 1, and the external feed pipe can be connected to the sealed feed port 2 through a flange to ensure the sealing during feeding;

[0030] The rigid expansion joint 3 and the sealing bag 4 are both fixed on the lower surface of the fixed frame 1, facing the sealing feed port 2, and the sealing bag 4 is sleeved on the outside of the rigid expansion joint 3. The rigid expansion joint 3 is also called a steel expansion joint, which is a device connecting two devices or pipelines, and is used to absorb or reduce the displacement or deformation of pipelines and equipment caused by thermal expansion and contraction, mechanical vibration, etc.; the sealing bag 4 is connected to the fixed frame 1 through the rigid expansion joint 3, the sealing feed port 2 is connected to the sealing bag 4, and the bottom of the sealing bag 4 is connected to the dust-free discharge head 8. When unloading, the material passes through the sealing feed port 2, the rigid expansion joint 3, the sealing bag 4 and the dust-free discharge head 8 in sequence;

[0031] The negative pressure suction system 7 is fixed on the fixed frame 1, and the working part of the negative pressure suction system 7 is connected with the sealing bag 4 to extract the dust in the sealing bag 4. The sealing bag 4 can be retracted and folded to change the height of the dust-free discharge head 8. Figure 1 As shown, the electric winch assembly is used to control the telescopic and folding of the sealing bag 4.

[0032] Specifically, Figure 1 and Figure 2 As shown, the electric hoist assembly includes: a hoisting motor 5, fixed to the upper surface of the fixing frame 1; a winding wheel 52, rotatably connected to the fixing frame 1, and the winding wheel 52 is linked to the output end of the hoisting motor 5; a steel cable 53, one end of which is wound on the winding wheel 52, and the other end is fixedly connected to the sealing bag 4. The winding wheel 52 is driven to rotate by the hoisting motor 5, and the winding wheel 52 can control the height of the sealing bag 4 to adjust up and down by winding the steel cable 53, so as to match the ash unloading operation at different heights;

[0033] Furthermore, the electric winch assembly also includes: a pressure roller frame 55, which is rotatably connected to the upper surface of the fixed frame 1, and the steel cable 53 is slidably connected to the pressure roller frame 55; a discharge position detection module 9, which is fixed to the upper surface of the fixed frame 1 and is used to detect the pressure roller frame 55. After the pressure roller frame 55 is detected, the winch motor 5 stops working. For example, in this embodiment, the discharge position detection module 9 is a sensor that can detect the position of an object, such as a photoelectric switch or a distance detection sensor, which is not specifically limited here. When the dust-free discharge head 8 does not contact the discharge point, for example: the discharge point is a truck, the dust-free discharge head 8 sags due to its own weight, so that the sealing bag 4 is under its own weight and the steel cable 53 is stretched straight, and the steel cable 53 can lift the pressure roller frame 55 away from the discharge position detection module 9;

[0034] To ensure dust-free unloading, the bottom of the dust-free unloading head 8 needs to be against the bottom of the truck dump box, and the dust-free unloading head 8 needs to be lowered until it contacts the unloading point before stopping. The unloading point provides support for the dust-free unloading head 8. At this time, the sealing bag 4 will shrink, the steel cable 53 is in a non-straightened state, and the height of the pressure roller frame 55 will drop to the same horizontal position as the unloading position detection module 9. The unloading position detection module 9 detects the pressure roller frame 55, and the hoisting motor 5 can stop working, realizing automatic adjustment of the unloading height;

[0035] It is worth mentioning that the installation height of the unloading position detection module 9 is determined by technicians in this field based on the optimal height of the pressure roller frame 55. The specific electrical connection between the unloading position detection module 9 and the winch motor 5 is a known public technology and will not be elaborated on here.

[0036] Further, such as Figure 1 As shown, segmented frames 41 are evenly fixed on the outer surface of the sealing bag 4, which facilitates the sealing bag 4 to be folded and retracted according to the segmented frames 41. The steel cable 53 passes through multiple segmented frames 41 in sequence to guide the steel cable 53 and prevent it from deflecting.

[0037] Embodiment 2

[0038] See also Figure 1 and Figure 2 As shown, the electric hoist assembly also includes a speed reduction commutator 51, through which the hoisting motor 5 is linked with the winding wheel 52, and the speed reduction commutator 51 plays the role of changing the output direction and reducing speed;

[0039] The guide wheel 54 is fixed on the fixing frame 1 , and the steel cable 53 is slidably connected to the guide wheel 54 .

[0040] Embodiment 3

[0041] Based on the above embodiments, Figure 1 , Figure 2 and Figure 3 As shown, the surface of the fixing frame 1 is equipped with a material level detection component 6, and the material level detection component 6 includes:

[0042] The material level switch 61 is fixed on the outer surface of the fixing frame 1. The material level switch 61, also called the material level switch, is used to monitor and control the silo or material level of various powdery or granular materials; the blower 62 is fixed on the outer surface of the fixing frame 1, and the blowing end is connected to the material level switch 61 through a conduit; the detection tube 611, the two ends of which are respectively fixed to the material level switch 61 and the dust-free unloading head 8, and the material level switch 61 is connected to the inner cavity of the dust-free unloading head 8 through the detection tube 611.

[0043] Exemplarily, when the blower 62 is working, the airflow is blown into the dust-free discharge head 8 through the material level switch 61 and the detection tube 611 in sequence. During normal discharge, the powder is continuously circulated in the dust-free discharge head 8 and will not block the detection tube 611. Then, the wind pressure generated by the blower 62 on the material level switch 61 is within the normal threshold value; and when the powder receiving device is full, the powder will accumulate in the dust-free discharge head 8. At this time, the excess powder will block the detection tube 611, causing the wind pressure of the material level switch 61 to exceed the normal threshold value, and the material level switch 61 will be automatically triggered and send a stop command to stop further filling operations;

[0044] The purpose is to prevent material overflow or equipment damage due to overloading by automatically controlling the input of materials;

[0045] It is worth noting that the material level switch 61 of this embodiment can be implemented by a pressure sensor, and the normal threshold value of the material level switch 61 is determined by a technician in this field by collecting the wind pressure measured by the material level switch 61 during normal unloading as the normal threshold value.

[0046] The exemplary implementation scheme of the present disclosure is described in detail above with reference to the preferred embodiments. However, it can be understood by those skilled in the art that, without departing from the concept of the present disclosure, various modifications and variations can be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present disclosure can be combined in various ways without exceeding the protection scope of the present disclosure, which is determined by the attached claims.
