Description

Technical Field

[0001] The utility model relates to the technical field of car tippers, in particular to a residual material clearing device for car tippers. Background Art

[0002] The car tipper is a large-scale mechanical equipment specially used for unloading bulk materials from railway open wagons. It is a continuous and efficient unloading equipment. It has been widely used in ports with large transportation volumes, domestic and foreign power plants, steel, cement, chemical and other departments. Due to the diverse forms of unloaded materials and the inherent structural characteristics of the car tipper, there are still a lot of residual materials waiting to be cleaned up after the car tipper unloads. Due to the diversity of residual materials and the differences in seasonal forms, it will bring different difficulties to the cleaning of residual materials, especially the compacted materials in the rainy season. Because the open wagons are used to transport materials, the materials are humid and have a high water content. The bottom of the open wagons contains the most water. After long-distance transportation, the materials are compacted and compacted on the bottom and side panels of the open wagons. After the car tipping in the rainy season, the materials stick to the bottom of the open wagons and cannot be unloaded. The thickness of the residual materials can reach more than 10 cm.

[0003] Most of the current methods for cleaning residual materials have various drawbacks. If manual cleaning is performed, it will take a long time, have poor results, be labor-intensive, and require many operators, which will greatly affect the efficiency of unloading and cleaning and seriously increase the retention time of trains in the factory; if high-pressure water jets are used to clean the train, the humidity of the residual materials will increase; if high-pressure air is used to clean the train, dust problems will occur; even if intelligent equipment such as cleaning trolleys with rotating brush heads are used, it is difficult to deal with stubborn and hardened residual materials; and adding a special residual material cleaning link will bring serious losses in economic benefits. On the one hand, it reduces the unloading efficiency of the tipping machine, and on the other hand, the company will incur a considerable amount of fines due to long unloading stops.

[0004] In order to protect the health and safety of workers, recycle residual materials, improve the efficiency of open wagon use and take environmental protection into consideration, a residual material clearing device for a car tipper is urgently needed to solve the problems existing in the prior art.

[0030] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below, and preferred embodiments of the present invention are given. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0032] Example:

[0033] See also Figure 1-Figure 6 The present embodiment provides a residual material clearing device for a car tipping machine, which is arranged on the car tipping machine 1, and comprises a water pipe 6, N air pipes and N nozzles for spraying water mist jets into the interior of the car compartment 2 on the car tipping machine 1; the water pipe 6 is connected to the N nozzles at the same time, and the N air pipes are connected to the N nozzles one-to-one; the air pressures in the N air pipes are different, so that each nozzle can spray water mist jets with different pressures, and different types of residual materials in the car compartment 2 can be cleaned by using water mist jets with different pressures or by combining water mist jets with different pressures; N is a natural number greater than or equal to 2.

[0034] Furthermore, the residual material cleaning device also includes a camera 9, through which the internal conditions of the carriage 2 can be observed, and the operator can decide what pressure of water mist jet to use for cleaning according to the type of residual materials in the carriage.

[0035] Furthermore, the opening and closing of each nozzle is independently controlled (specifically, achieved through a valve), so that each nozzle can be opened or closed independently, thereby achieving the goal of the residual material cleaning device spraying a water mist jet of a target pressure alone or spraying a variety of water mist jets of different pressures at the same time.

[0036] Specifically, in this embodiment, N is equal to 2, that is, the present application includes two nozzles, namely a first nozzle 7 and a second nozzle 8, wherein the first nozzle 7 is supplied with compressed gas through the first air pipe 4, and the second nozzle 8 is supplied with compressed gas through the second air pipe 5, and cleaning water is supplied to the first nozzle 7 and the second nozzle 8 at the same time through the water pipe 6, wherein the air pressure in the first air pipe 4 is greater than the compressed air in the second air pipe 5, that is, the injection pressure of the first nozzle 7 is greater than that of the second nozzle 8. In this embodiment, the first nozzle 7 is a high-pressure nozzle, and the second nozzle 8 is a medium-pressure nozzle.

[0037] Generally, the residual material in the carriage 2 is either dry bulk residual material 11 or compacted residual material 10, or dry bulk residual material 11 and compacted residual material 10 exist at the same time, so the residual material cleaning device in this embodiment can cope with different types of residual materials well; when there is dry bulk residual material 11 in the carriage, this type of residual material only needs relatively low-pressure water mist to be cleaned, so only the second nozzle 8 needs to be turned on to complete the cleaning; when there is compacted residual material in the carriage, this type of residual material has high humidity and is compacted on the bottom or side wall of the car, so it is necessary to turn on the first nozzle 7 and use relatively high-pressure water mist to complete the cleaning; further, when there are both dry bulk residual material and compacted residual material in the carriage, the first nozzle and the second nozzle are turned on at the same time for cleaning.

[0038] Preferably, the nozzle in the residual material cleaning device of this embodiment is installed on the tipping machine by a bracket, and rotates together with the unloading action of the tipping machine, and cleans the carriage after the tipping machine turns over to unload the loaded material 3, such as Figure 1 and Figure 2 shown; Figure 2 This is a schematic diagram of the unloading of the car tipper. In this state, the opening of the car is located at the lower end, and a water mist jet is sprayed into the interior of the car. The residual material and water flow can flow out of the car freely with gravity, so as to achieve the purpose of cleaning the residual material; further, each nozzle can be installed on a bracket, or each can be independently installed through the bracket; further, in order to achieve the cleaning of the entire car, generally multiple nozzles with the same spray pressure need to be set, and the nozzles with the same spray pressure can be arranged in rows when setting. At the same time, in some embodiments, each nozzle can also achieve position and spray angle adjustment through the bracket. The specific setting depends on the actual structure of the car tipper and the cleaning requirements of the car.

[0039] Furthermore, in order to improve the dust suppression and cleaning effects, the nozzle in this embodiment includes a main nozzle 119 and M sub-nozzles 116 arranged around the main nozzle 119, wherein the spray direction of the main nozzle 119 intersects with the spray directions of each sub-nozzle 116 at one point, and M is a natural number greater than or equal to 2. The water mist sprayed by the main nozzle 119 intersects with the water mist sprayed by the sub-nozzle 116 at one point to achieve the effect of secondary atomization, and the secondary atomization makes the water particles finer, which is conducive to improving the dust suppression effect; in this embodiment, the secondary atomized water mist jet is used to impact the residual material in the open car, so as to achieve the purpose of removing the residual material and suppressing dust, which can save the unloading time and recover the residual material.

[0040] Preferably, the angle between the injection direction of the main nozzle 119 and the injection direction of the secondary nozzle 116 is 30°-90°, and the specific angle value can be set by personnel in this field according to actual conditions; at the same time, in some embodiments, the secondary nozzle may be set to an angle-adjustable structure, so that the angle between the main nozzle and the secondary nozzle can be adjusted according to needs in actual applications.

[0041] Preferably, each secondary nozzle 116 is evenly arranged around the circumference of the main nozzle 119; in this embodiment, M=3, three secondary nozzles 116 are evenly arranged along the circumference, and the interval angle between two adjacent secondary nozzles is 120°. Figure 3 As shown (the structures of all nozzles in this embodiment are consistent).

[0042] See also Figure 4-Figure 6In this embodiment, the nozzle includes a shunt pipe 104, a guide pipe 103 and a feed sleeve 101 which are arranged in sequence, and an air inlet cavity 105 and a liquid inlet cavity 106 are provided on the feed sleeve 101. A main nozzle 119 and M sub-nozzles 116 are provided on the front end surface of the shunt pipe 104, wherein the spraying direction of the main nozzle coincides with the axial direction of the nozzle; a plurality of guide holes are provided on the guide pipe 103, and the main nozzle 119 and each sub-nozzle 116 are respectively connected to the air inlet cavity 105 and the liquid inlet cavity 106 through the guide holes, that is, the main nozzle and each sub-nozzle are connected to the air inlet cavity 105 and the liquid inlet cavity 106.

[0043] See also Figure 4 and Figure 5 , the guide pipe 103 is provided with an annular air chamber 110 and a plurality of first air inlet guide holes 107, the input side of the annular air chamber 110 is connected to the air inlet cavity 105 through the first air inlet guide hole 107, the output side of the annular air chamber 110 is provided with M air outlet holes 120 and an air outlet annular channel 121, a single air outlet hole 120 is connected to the corresponding secondary nozzle 116 through the corresponding second air inlet guide hole 112 provided on the shunt pipe 104, and the air outlet annular channel 121 is connected to the main nozzle 119, so that the air inlet cavity 105 supplies compressed gas to the main nozzle and each secondary nozzle. Preferably, the input end of the air inlet cavity 105 can be connected to the air delivery pipe (such as a connection form of threaded fitting with a sealing gasket), so that the compressed gas in the air delivery pipe can enter the air inlet cavity 105.

[0044] Please continue to see Figure 4 The guide pipe 103 is provided with a second liquid inlet guide hole 109 and M first liquid inlet guide holes 108 arranged around the second liquid inlet guide hole 109, and the second liquid inlet guide hole 109 is connected to the liquid inlet cavity 106 and the main nozzle 119; the diverter pipe 104 is provided with M third liquid inlet guide holes 111, and the third liquid inlet guide holes 111 are connected to the secondary nozzle 116 in a one-to-one manner, and one end of the first liquid inlet guide hole 108 is connected to the liquid inlet cavity 106, and the other end thereof is connected to the corresponding third liquid inlet guide hole 111, so that the liquid inlet cavity 106 supplies cleaning water to the main nozzle and each secondary nozzle. Preferably, the liquid inlet cavity 106 includes at least one liquid inlet port 102, and the water delivery pipe 6 supplies cleaning water to the liquid inlet cavity 106 through the liquid inlet port 102.

[0045] Please continue to see Figure 4The secondary nozzle 116 includes a first gas-liquid mixing chamber 115, a gas passage chamber 114 and a liquid passage chamber 113. The second gas inlet guide hole 112 is connected to the gas passage chamber 114. The gas passage chamber 114 is connected to the first gas-liquid mixing chamber 115 through K spiral gas inlet holes evenly distributed along the circumferential direction, so that the gas enters the first gas-liquid mixing chamber 115 in a spiral manner; the third liquid inlet guide hole 111 is connected to the liquid passage chamber 113. The liquid passage chamber 113 is connected to the liquid passage through L liquid passage holes evenly distributed along the circumferential direction. The liquid passage passage is connected to the first gas-liquid mixing chamber 115. The first gas-liquid mixing chamber 115 is provided with a nozzle. K and L are both natural numbers greater than or equal to 2. In this embodiment, K and L are both 4. Specifically, when the compressed gas entering in the spiral meets the liquid flow supplied by the liquid passage, the spiral airflow generates strong shear force and impact force on the liquid flow to break the liquid flow, forming a gas-liquid mixed flow to achieve the first atomization, that is, the water mist jet sprayed from the secondary nozzle is a primary atomization.

[0046] Preferably, the first gas-liquid mixing chamber 115 is conical, and its taper is 50°-70°; the conical structure can increase the spray pressure of the secondary nozzle, and at the same time facilitate the formation of high-speed spiral airflow, thereby improving the atomization effect.

[0047] See also Figure 4 and Figure 6 The main nozzle 119 includes a second gas-liquid mixing chamber 123, a central nozzle 122 is provided at the outlet end of the second liquid inlet guide hole 109, and the central nozzle 122 extends into the second gas-liquid mixing chamber 123. A gas vortex generator 117 is provided between the gas outlet annular channel 121 and the second gas-liquid mixing chamber 123, and a spray hole sheet 118 is provided at the nozzle of the second gas-liquid mixing chamber 123, and the atomized water mist jet is sprayed out through the spray hole sheet. The gas vortex generator realizes the formation of a vortex airflow in the second gas-liquid mixing chamber, and the vortex airflow collides and mixes with the liquid jet of the central nozzle to realize the first atomization, so that the main nozzle sprays a water mist jet that is also atomized once.

[0048] Furthermore, when the secondary nozzle is set to an angle-adjustable structure in some embodiments, the third liquid inlet guide hole 111 and the second air inlet guide hole 112 can be divided into two sections, one of which is located on the diversion tube 104, and the other end is located on the secondary nozzle; the secondary nozzle can be installed on the diversion tube 104 through a rotating bracket, and the two sections of the third liquid inlet guide hole and the two sections of the second air inlet guide hole can be connected by a hose, and the hose can be deformed to meet the angle adjustment requirements of the secondary nozzle.

[0049] The residual material cleaning device of this embodiment adopts two-phase flow (i.e., air-water two-phase atomization technology) to clean residual materials, which can not only clean open cars more efficiently, but also avoid the problem of dust. Experiments have confirmed that the two-phase jet has a stronger erosion ability than the pure water jet, and the use of air-water two-phase jet can save 30%-50% of water compared with the pure water jet. At the same time, experiments have also proved that when the intake pressure is 0.6MPa, the average erosion ability of the gas-liquid two-phase jet can be increased by nearly 28% compared with the pure water jet. This embodiment adopts the combination of the main nozzle and the secondary nozzle to achieve secondary atomization to obtain finer water particles, which can further improve the dust suppression effect while ensuring the cleaning ability, and prevent the dust from causing environmental pollution and harming the health of the workers.
