Description

Technical Field

[0001] The present invention relates to the technical field of coal feeders, in particular to a push rod type vibrating coal feeder and a cleaning method thereof. Background Art

[0002] An invention is disclosed in the prior art, with the authorization announcement number CN205328119U, the authorization announcement date of June 22, 2016, and the name of an anti-self-flow activation coal feeder. It has a vertical cylindrical feeding box. Above the feeding box is the feeding port. The bottom of the feeding box has elastic supports. An electric vibrator is connected to the side of the feeding box. Above the feeding box inside, there is a shunt plate. Below the shunt plate, there is a curve groove. The bottom of the curve groove is the discharge port. Between the opposite sides at the discharge port of the feeding box, there are two to six horizontal through holes respectively. Straight rods are inserted into the through holes. The activation coal feeder in the prior art organically combines the feeding function and the function of activating materials, effectively eliminating the problems of bulking and blocking of the bin. However, there are still the following problems: Due to different coal qualities and different water contents, the coal in the coal bin will stick into lumps. When the coal feeder feeds, although the materials will automatically fall while being loosened by vibration, due to the lumping of the materials, the materials cannot be loosened in time and effectively, resulting in a delay in feeding.

[0003] Then, another invention is disclosed in the prior art, with the authorization announcement number CN204896699U, the authorization announcement date of December 23, 2015, and the name of an activated belt coal feeder, including a motor frame, vibration springs, a motor frame, a feeding curve groove, a coal dropping pipe, vibration isolation springs, and a bracket. An activation block is arranged in the middle inside the motor frame and above the feeding curve groove. The longitudinal section of the activation block is an isosceles trapezoid. The two sides of the activation block are attached to the side walls of the motor frame. The activation block is fixed to the motor frame with bolts. At the center of the top of the activation block, there is an activation rod, and the top end of the activation rod is a disc-shaped rod head. In the prior art, under the action of the vibration motor, the activation rod can extend into the materials to strengthen the disturbance of the materials, making the materials fully loosened and activated. Although the prior art improves the activation to a certain extent through the activation rod, for coal with a high water content, the materials are lumped very tightly, and it is difficult to fully activate the materials with the activation rod. There are still a large number of lumped coal materials easily generated. Moreover, the disturbance degree of the activation rod is slow, and the disturbance range is small, which cannot achieve the effect of rapid activation. The coal materials are easy to block and accumulate in the conveying pipe. After the accumulation occurs, since the coal conveying bottom plate below cannot be opened for cleaning, the staff can only clean by knocking and flushing from the top. However, during the cleaning process, it is impossible to directly clean the blocked part at the bottom of the coal conveying pipe. Summary of the Invention

[0004] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0005] In view of the fact that the above-mentioned existing coal is prone to blockage and accumulation in the conveying pipe, after accumulation occurs, the coal conveying bottom plate below cannot be opened for cleaning, and the staff can only clean it by knocking and top flushing. However, during the cleaning process, it is impossible to directly clean the blockage at the bottom of the coal conveying pipe, so the present invention is proposed.

[0006] The purpose of the present invention is to provide a push rod type vibrating coal feeder, which aims to solve the problem that when some models of coal feeders are blocked, they cannot be cleaned because the bottom material conveying pipeline is closed when the blockage occurs, and during the cleaning process, the blocked part of the coal feeder cannot be cleaned directly.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1

[0031] Reference Figure 1 , which is the first embodiment of the present invention, and provides a push rod type vibrating coal feeder, including a discharge assembly 100, which includes a hopper 101, a conveying pipe 102 connected to the output end of the hopper 101, a collecting bin 103 receiving and cooperating with the output end of the conveying pipe 102, and a plug plate 104 cooperating with the conveying pipe 102, a movable assembly 200, which cooperates with the bottom of the conveying pipe 102 to form a closed material transfer, and includes a fixed frame 201 fixedly connected to the side wall of the conveying pipe 102 and a movable bin 202 cooperating with the bottom of the conveying pipe 102 to transfer materials.

[0032] Furthermore, the feed pipe 102 includes a drainage section 102a and a bottom section 102b; a notch is provided on one side of the drainage section 102a to cooperate with the plug plate 104, the cross-section of any part of the bottom section 102b is U-shaped, and the opening direction is downward, the plug plate 104 includes a fixed end 104a and a telescopic end 104b, the fixed end 104a is connected to the inner wall of the fixed frame 201, and the telescopic end 104b is driven by a motor to cooperate with the notch of the drainage section 102a, and a limit plate 201a is symmetrically arranged at the bottom end of the fixed frame 201, and an arc groove 201a-1 is provided at the bottom of the limit plate 201a.

[0033] Specifically, the opening end of the hopper 101 is set to be relatively large to receive pulverized coal over a larger range. After the pulverized coal enters the interior of the conveying pipe 102 through the hopper 101, it slides down along the diversion section 102a of the conveying pipe 102. The inclination angle of the diversion section 102a is set within the range of 60° to 75°. Within this range, when the pulverized coal passes through the diversion section 102a, it is not easy to adsorb on the side wall of the diversion section 102a due to the too large inclination angle. In principle, the larger the inclination angle, the less likely the pulverized coal is to adsorb on the side wall of the diversion section 102a. However, when the inclination angle is too large, the pulverized coal will fall at a relatively fast speed, and some pulverized coal may even directly fall on the bottom surface of the movable bin 202 without passing through the diversion section 102a. When the impact force is large, the stronger the adhesion of the pulverized coal adsorbed on the bottom section of the hopper. Therefore, when the inclination angle is large, the pulverized coal passing through the diversion section 102a will not produce a certain buffer, and the pulverized coal directly falling on the bottom section 102a without passing through the diversion section 102a will adhere to the bottom section 102a with stronger adsorption, which will accelerate the accumulation of pulverized coal on the bottom surface of the movable bin 202. Therefore, the inclination angle of the diversion section 102a of the present invention is set between 60° and 75°, so as to not only improve the conveying rate of the pulverized coal, but also prevent the situation of pulverized coal adhering to the bottom surface of the movable bin 202 from getting worse. Finally, the pulverized coal slides down along the output end of the movable bin 202 into the collection bin 103. During this process, the control of the plug plate 104 can be realized by a motor. The plug plate 104 can control the coal conveying amount. When the telescopic end 104b of the plug plate 104 completely closes the notch of the diversion section 102a, the pulverized coal can no longer be conveyed.

[0034] Embodiment 2

[0035] Refer to Figures 1 to 6 , which is the second embodiment of the present invention. Different from the previous embodiment, it further includes four groups of hydraulic cylinders 201b symmetrically arranged on the side wall of the fixed frame 201. The bottom of the hydraulic cylinder 201b is connected with a hook 201b-1. Any cross-section in the length direction of the movable bin 202 is U-shaped, and the opening direction is upward and cooperates with the bottom section 102b to form a closed bottom. Two groups of displacement columns 202a and four groups of pull rings 202b are symmetrically arranged on the side wall of the movable bin 202.

[0036] Furthermore, the contact end of the hole in the pull ring 202b with the hook 201b-1 is set as a plane. The plane distance of the contact end of the pull ring 202b is equal to the transverse displacement length of the arc-shaped groove 201a-1. The displacement column 202a slides in the arc-shaped groove 201a-1. A vibration member 202c is arranged at the bottom of the movable bin 202 in cooperation with the pull ring 202b and the hook 201b-1. The vibration member 202c is driven by a motor.

[0037] Specifically, a partial square plane is provided at the connection between the hopper 101 and the material conveying pipe 102, and the fixing frame 201 is fixed on the square plane, so as to ensure the overall stability of the device. A limiting plate 201a is provided at the bottom of the fixing frame 201, and an arc-shaped groove 201a-1 is formed on the limiting plate 201a. The lateral displacement distance of the arc-shaped groove 201a-1 is set depending on the separation distance between the movable bin 202 and the material conveying pipe 102. The lateral displacement distance of the arc-shaped groove 201a-1 can be set according to the on-site situation, and the distance between the movable bin 202 and the material conveying pipe 102 can be opened to (the maximum may be limited by the surrounding devices at the work site), which is more convenient for cleaning.

[0038] Specifically, four hydraulic cylinders 201b are arranged on the fixing frame 201, and a hook 201b-1 is arranged at the lower mating end of the hydraulic cylinder 201b. The hook cooperates with the pull ring 202b on the movable bin 202. Here, the pull ring 202b is different from the conventional one. Most ordinary pull rings are set as arc-shaped and the fixed end of the pull ring 202b is set as a rotational connection. When the part of the hook 201b-1 connected to the hydraulic cylinder 201b contacts and displaces with the conventional pull ring, the force application point will change, resulting in a large loss of the hydraulic cylinder 201b. Therefore, in our invention, the inner ring surface where the pull ring 202b contacts the hook 201b-1 is set as a horizontal plane, and the length of the horizontal plane of the pull ring 202b is equal to the lateral displacement distance of the arc-shaped groove 201a-1, so as to ensure that the maximum displacement distances of the two are the same and the pull ring 202b and the hook 201b-1 are not on the same horizontal plane, which may cause deviation in the force application angle of the output end of the hydraulic cylinder 201b, resulting in wear.

[0039] In summary, when it is necessary to clean the pulverized coal in the movable bin 202 after the pulverized coal conveying is completed, the hydraulic cylinder 201b can be controlled to extend and retract downward. When the hook 201b-1 displaces downward, the displacement column 202a displaces along the arc surface of the arc-shaped groove 201a-1, so as to realize displacement downward and in the direction perpendicular to the bottom section 102b of the material conveying pipe 102, ensuring that the opening sizes at each position are the same after the movable bin 202 is opened, which is more convenient for cleaning. The vibrating member 202c can vibrate during the operation of the coal feeder and can also vibrate during cleaning, which can increase the cleaning efficiency of the pulverized coal adsorbed on the bottom of the movable bin 202.

[0040] Embodiment 3

[0041] Refer to Figures 1 to 6 , which is the third embodiment of the present invention. This embodiment further provides a cleaning method. It includes a cleaning component 300, which is arranged on the side of the movable bin 202 away from the collection bin 103, and includes a bracket 301 and a water gun 302 clamped to the bracket.

[0042] Furthermore, the water gun 302 flushes the surface of the movable bin 103, and both the coal material and water enter the collection bin 103. The water is pumped out through a water pump after screening, thus realizing the recycling of wastewater.

[0043] Specifically, the bracket 301 is arranged on the right - hand - side for easier use. The water gun 302 can be hung on the bracket 301 for convenient storage and use.

[0044] Specifically, the hydraulic cylinder 201b is controlled to open the movable bin 202. After the movable bin 202 is opened, the inner wall of the movable bin 202 is cleaned by the water from the water gun. The water supply of the water gun 302 comes from the on - site water source, and the pressure of the water gun 302 is set to 1 mpa. This not only achieves a better cleaning effect but also saves water. Since the movable bin 202 moves along a direction perpendicular to the bottom section 102b of the feeding pipe 102 when it is opened, after opening, the output end of the movable bin 202 can still flush the coal material and water into the collection bin 103, thus realizing the reuse of wastewater.

[0045] In the process of coal wastewater recycling, chemical precipitation or physical centrifugation can be used to separate the coal wastewater from the coal residue. Finally, the water is pumped out by a pump for recycling.

[0046] In addition, to provide a concise description of the exemplary embodiments, not all features of the actual embodiments may be described (i.e., those features that are not relevant to the currently considered best mode of implementing the present invention or those features that are not relevant to implementing the present invention).

[0047] It should be understood that in the development of any actual implementation, as in any engineering or design project, a large number of specific implementation decisions may be made. Such development efforts may be complex and time - consuming, but for those of ordinary skill in the art who benefit from this disclosure, without excessive experimentation, such development efforts will be a routine task of design, manufacturing, and production.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
