Abstract

The utility model discloses an exhaust gas heating device for a compression refuse collector, which comprises a three-way valve (4), an exhaust pipe (2), and a U-shaped heating pipeline (5). The U-shaped heating pipeline (5) is composed of a heating pipe (7), a ventilation pipe (8) and two tail pipes (6). The heating pipe (7) is fixed on the bottom plate of the compartment (1) of a compression refuse collector. The ventilation pipe (8) is vertically welded onto one side of the heating pipe (7) positioned closer to the exhaust pipe (2). The two tail pipes (6) are vertically welded onto the two opening ends of the heating pipe (7). The ventilation pipe (8) and the two tail pipes (6) are led out through three holes in the bottom plate of the compartment. The ventilation pipe (8) and the exhaust pipe (2) are connected together through the three-way valve (4).

The bottom plate can be heated more uniformly. Meanwhile, the entire heating device is simpler in structure, and more convenient in disassembly and maintenance.

Description

Compression type garbage truck tail gas heating device

Technical field

The utility model relates to a kind of waste-skip tail gas heating device, especially relates to a kind of compression type garbage truck tail gas heating device.

Background technology

Compression type garbage truck in the course of the work, the rubbish of collecting mostly is house refuse, in the process of compressed garbage, often have sewage and be extruded out, some lower areas of temperature especially in the winter time, the garbage leachate that is extruded out can freeze together with rubbish at cabin floor place, thereby cause discharging not smooth, this situation, has not only increased the difficulty of compression type garbage truck discharging, has also reduced the in-use performance of compression type garbage truck simultaneously; At present, although more existing devices that utilize tail gas to heat compartment, but its integral structure is more complicated, its part of directly carrying out interchange of heat is all the square tank body that covers the sealed type of cabin floor conventionally, because its heat exchange section area is larger, so the tail gas of car can not carry out interchange of heat therein equably, reduced the degree of utilization of tail gas, and its installation process is had relatively high expectations to technique, be also unfavorable for dismantling and keeping in repair.

Summary of the invention

For above-mentioned technical matters, the utility model provides a kind of compression type garbage truck tail gas heating device, not only can efficiently utilize vehicle exhaust to heat cabin floor, and it is simple in structure, heat exchanging process is more even, it is simple and direct, not fragile to install, and dismounting and easy to maintenance.

To achieve these goals, the technical solution adopted in the utility model is: a kind of compression type garbage truck tail gas heating device, comprise triple valve, offgas duct, the heating pipe line taking the shape of the letter U, described heating pipe line both ends open, described heating pipe line is by heating pipe, breather pipe and two tail pipes form, described heating pipe is fixed on the base plate of compression type garbage truck wagon, described breather pipe is vertically welded in heating pipe near one side of offgas duct, described two tail pipes are vertically welded in two open ends of heating pipe, on cabin floor, have three holes, described breather pipe and two tail pipes just stretch out from cabin floor by three holes, described breather pipe is connected by triple valve with offgas duct.

As a kind of improvement of the present utility model, from breather pipe to and its nearest tail pipe the internal diameter of heating pipe be less than the internal diameter of all the other pipelines of heating pipe.

As further improvement of the utility model, described breather pipe ventilates to being flexible coupling by fire prevention with offgas duct and is connected with triple valve.

As of the present utility model, further improve, the distance between two parallel edges of described heating pipe line is that every one side is to the twice of compression type garbage truck wagon two lateral extents.

The utility model adopts two ends with the U-shaped heating pipe line of tail pipe, has improved greatly the degree of utilization of tail gas; In addition, by the mode of different internal diameters is set at pipe line two parts, can make tail gas that offgas duct the discharges heat exchanging process in whole heating pipe line more even; In addition, the distance between two parallel edges of heating pipe line is every one side to the twice of compression type garbage truck wagon two lateral extents, thereby the heat that the every part of whole base plate in compartment is obtained is more balanced; Utilizing fire prevention to ventilate to being flexible coupling is connected with breather pipe offgas duct by triple valve, not only can effectively reduce the damage bringing to heater block due to breather pipe or offgas duct shake in the course of the work, and can make the dismounting of whole heating arrangement and the process of maintenance more convenient; By adjusting the position of heating pipe line on cabin floor, can make the heating efficiency of tail gas higher, make baseplate heated more even.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation;

Fig. 2 is the structural representation of the utility model heating pipe line.

In figure: 1, compression type garbage truck wagon, 2, offgas duct, 3, fire prevention ventilates and be flexible coupling, 4, triple valve, 5, heating pipe line, 6, tail pipe, 7, heating pipe, 8, breather pipe.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As depicted in figs. 1 and 2, the utility model comprises triple valve 4, offgas duct 2, the heating pipe line 5 taking the shape of the letter U, described heating pipe line 5 both ends openings, described heating pipe line 5 is by heating pipe 7, breather pipe 8 and two tail pipes 6 form, described heating pipe 7 is fixed on the base plate of compression type garbage truck wagon 1, described breather pipe 8 is vertically welded in heating pipe 7 near one side of offgas duct 2, described two tail pipes 6 are vertically welded in two open ends of heating pipe 7, on cabin floor, have three holes, described breather pipe 8 and two tail pipes 6 just stretch out from cabin floor by three holes, described breather pipe 8 is connected by triple valve 4 with offgas duct 2.

In the time need to heating the base plate of compression type garbage truck wagon 1, start the engine, open the path that triple valve 4 leads to heating pipe line 5, offgas duct 2 starts emission, and tail gas enters heating pipe line 5 through breather pipe 8, in the process of heating pipe 7 of flowing through, completes interchange of heat, finally by the tail pipe 6 at two ends, discharge, when not needing to heat, close the path that triple valve 4 leads to heating pipe line 5, thereby the tail gas of car is discharged by triple valve 4 and the direct-connected end of offgas duct 2.

For the degree of utilization of tail gas is further improved, can make breather pipe 8 to and its nearest tail pipe 6 between the internal diameter of heating pipe 7 be less than the internal diameter of heating pipe 7 all the other pipelines.

For the damage that prevents that the shake of working process Center Vent tube 8 and offgas duct 2 from bringing to this device, and make the dismounting of this device and maintenance process easier, can ventilate to being flexible coupling with fire prevention 3 be connected with offgas duct 2 breather pipe 8 with triple valve 4.

For make compression type garbage truck wagon 1 the every part of whole base plate be heated more balancedly, can make the distance between two parallel edges of heating pipe line 5 is that every one side is to the twice of 1 liang of lateral extent of compression type garbage truck wagon.
