Technical Field

The utility model relates to a vehicle tail gas conveying system, especially a vehicle tail gas conveying system for garbage truck. Furthermore, the utility model discloses still relate to a garbage truck who is provided with this kind of vehicle exhaust conveying system.

Background

In the existing garbage disposal operation, garbage collected from each community or business is generally transported to a garbage disposal station by a garbage transport vehicle, and then the garbage transport vehicle directly transports the carried garbage to the garbage disposal station for centralized disposal.

It is well known that conventional waste, particularly kitchen waste, often contains moisture. After the compression and volume reduction of the waste in the loading bin of the waste transport vehicle, this moisture will accumulate in the bottom of the loading bin in the form of contaminated water. In northern China, particularly in extremely cold regions such as northeast China in winter, the existence of the moisture can cause the phenomenon of icing at the bottom of the garbage loading box in the long-distance garbage transportation process, so that the garbage cannot be normally unloaded or cannot be completely unloaded when the garbage is unloaded at a garbage disposal station.

In order to solve the problems, the existing method is to shorten the transportation time as much as possible so as to reduce the severity of the icing of the box body, but the transportation time is greatly influenced by the actual situation according to the position relationship between the local transportation station and the terminal processing station, and the use and the scheduling of the garbage transportation vehicle are influenced; or after the frozen position is melted, the unloading operation is carried out, but the transportation time is inevitably prolonged, so that the utilization rate of the garbage transportation vehicle and the overall efficiency of garbage transportation are influenced.

In addition, in the case of solving the icing problem using the following heating method, there are also the following problems:

(1) Electric heating: the required heating power is large, the energy consumption is high, the heating structure is complex in arrangement, the electricity is difficult to get under the condition of using the box body electric heater, and the actual heating effect is limited;

(2) Heating cooling liquid: the diesel heater, the circulating water pump and the whole set of circulating water path are additionally arranged on the box body, so that the whole structure is complex in arrangement and limited by space arrangement. In addition, the diesel oil heater has low power and low heating speed, additionally consumes diesel oil, causes energy waste and has poor environmental protection performance.

Thus, the use of the heat contained in the exhaust gases of vehicles is considered in the industry to avoid the above-mentioned icing phenomena.

In systems using exhaust gas discharged from vehicles as a heat source, an additional path is usually connected to an exhaust gas discharge pipeline, so that the exhaust gas discharge path is divided into two branches, one branch is directly connected to the atmosphere, and the other branch is connected to a part needing to use heat of the exhaust gas. In order to better control the usage of the two branches, a stop valve is usually provided in each of the two branches, and the control of the exhaust gas flow and the usage is realized by controlling the opening and closing of the two stop valves. However, this arrangement may cause a malfunction such as a vehicle stall due to a control error.

Accordingly, there is a need in the art for a tail gas delivery system that is stable and reliable in control, requires a small number of components, is low in cost, is flexible and simple to install, and thereby more effectively avoids the above-mentioned icing phenomena.

Detailed Description

The tail gas conveying system 1 for a garbage truck according to the present invention will be described with reference to the accompanying drawings. The exhaust gas delivery system 1 may be attached to the refuse transport vehicle by a permanent attachment means such as welding or a detachable attachment means such as a flange connection.

Referring to fig. 1a and 1b, the exhaust gas conveying system 1 mainly comprises a reversing device 11, a conveying pipeline 12 and a connector 13. Referring to fig. 2a-2d, the reversing device 11 may be in the form of a three-way valve comprising an inlet end a, a first outlet end B and a second outlet end C. The inlet end a is adapted to receive exhaust gases from a refuse transport vehicle and is connectable to an exhaust gas outlet (not shown) of the refuse transport vehicle, either by a detachable connection, such as a flange connection (as shown in fig. 2a-2 d), or by a permanent connection, such as welding. The first outlet end B is open directly to the atmosphere, while the second outlet end C is connected to one end of the delivery pipe 12, again by a removable connection such as a flanged connection or by a permanent connection such as welding, to allow fluid communication between the two. The other end of the conveying pipe 12 is connected to a connector 13 for fluid communication with the waste loading bin of the waste transport vehicle via the connector 13, see fig. 1b.

Referring to fig. 2c and 2d, the reversing device 11 used in the vehicle exhaust gas conveying system 1 of the present invention can be formed by connecting two pipes by welding or the like. The two ducts may have the same or different diameters and although the axes of the two ducts constituting the reverser 11 are shown in the figures as being at 90 degrees to one another, it is equally conceivable to interconnect them at different angles to be equally feasible. The angle may be determined according to the specific installation of the vehicle exhaust gas delivery system 1 on the refuse transport vehicle on which it is installed. Further, although the ports a, B, C may have different diameters as can be known to those skilled in the art, as shown in the drawing, it is preferable that the three ports a, B, C are provided to have the same diameter, and more preferably, the same hole diameter as the exhaust gas discharge port. Again, although the two conduits are shown in the figures as having circular cross-sections, it is equally possible to use other cross-sections (e.g. rectangular, etc.).

The commutation means 11 can be switched between a first state shown in fig. 2c and a second state shown in fig. 2 d. In a first state the diverter device 11 directs the off-gas from port a towards port B and then directly to the atmosphere, while in a second state the diverter device 11 directs the off-gas from port a towards the conveying pipe 12 and then to the waste bin.

The commutation means 11 is provided with control means to achieve this state switching. The control device includes an actuator and a condition maintaining member. The actuator may be in the form of a horn 110, as shown in fig. 2c and 2d, the horn 110 having a corner end 110a, a pivot end 110b, and a free end 110c. The angle 110 is free to pivot about the pivot end 110 b. The condition maintaining member may be in the form of an extension spring 111. One end 111a of the tension spring 111 is pivotable about a pin P1 (see fig. 2a and 2 b) fixed to the housing of the reversing device 11. Although the pin P1 is disposed at the intersection of the joints of the two pipes in the drawings, see fig. 2c and 2d, the present invention is not limited thereto. The other end 111b of the tension spring 111 is connected to the corner end 110a of the angle piece 110 by a pivot P2, wherein the pivot P2 is fixed with respect to the angle piece 110, but the one end 111b of the tension spring 111 can rotate around the pivot P2. The tension spring 111 is arranged such that when the horn 110 reaches the first state shown in fig. 2c and the second state shown in fig. 2d, the tension spring 111 is able to maintain the respective states.

In alternative embodiments, it is contemplated by those skilled in the art that the actuator may be provided in the form of, for example, a wrench-like handle and the condition maintaining member may be provided in the form of, for example, a catch or stop. As long as they can perform the actuation and state holding functions, respectively, and thus, will not be described in detail herein.

A reversing element 112 in the form of a disc is arranged in the reversing device 11, see fig. 2a and 2b. The direction-changing member 112 is fixedly connected to the angle member 110 via a pivot axis P3, so that the relative positional relationship between the direction-changing member 112, the pivot axis P3 and the angle member 110 is maintained, the direction-changing member 112 and the pivot axis P3 are coplanar with a first plane, and the first plane is substantially perpendicular to a second plane in which the angle member 110 is located. Thus, when the angle 110 pivots about the pivot end 1110b, the diverter 112 can rotate synchronously therewith.

Thus, when the angle 110 is in the first state shown in fig. 2C, the diverter 112 blocks the outlet end C, thereby directing exhaust from port a to port B for direct discharge to the atmosphere. When the angle is in the second condition shown in figure 2d, the diverter 112 blocks port B, thereby directing the exhaust gases from port a towards the conveying pipe 12 and then towards the waste bin.

The change of state of the angle 110 can be achieved by manually pulling the angle 110 to pivot about the pivot axis P3. Alternatively, the change of state of the horn 110 may be effected by a flexible shaft mechanism 1131, see fig. 3. The flexible shaft mechanism 1131 comprises a flexible shaft 1131, one end of the flexible shaft 1131 being connected to the horn 110, preferably to the free end 110c thereof, to enable the horn 110 to pivot about a pivot P3. The other end of the flexible shaft 1131 is connected to a control handle K. The control handle K may be provided in the cab R to be controlled by the operator (or driver), or may be provided at any suitable position of the vehicle to be controlled by the operator at an appropriate time. Alternatively, the flexible shaft 1131 may be fixed to the reversing device 11 by means of a fixing bracket 1132, for example to its housing.

According to the utility model discloses a cross-section of pipeline 12 that uses in tail gas conveying system 1 can have multiple shape, for example, circular, rectangle etc. and its cross-sectional dimension and the material that uses all can select according to the actual condition. Alternatively, insulation may be provided around the periphery of the transfer duct 12 to minimize the amount of heat lost from the exhaust gases through the transfer duct 12, thereby increasing the use of waste heat from the vehicle exhaust gases.

According to the utility model discloses a be connected between connector 13 and the rubbish loading bin that uses in tail gas conveying system 1 is a separable interface connection. In other words, the connector 13 is in direct contact with the waste loading bin by abutment, and this connection does not affect the normal unloading operation of the loading bin, while ensuring the normal transport of the off-gases. Preferably, the connector 13 is attached to the bottom or side of the loading compartment close to the bottom of the compartment to better ensure the efficient use of the heat of the exhaust gases.
