Abstract
The utility model discloses a kind of low noise and throw device, comprise and throw shell, it is characterized in that: described in throw in shell and be provided with and throw impeller mechanism, and throw shell and be communicated with discharging mechanism; The described impeller mechanism that throws comprises and throws frame plate and throw blade, throws the frame plate external power supply that is in transmission connection, and throws blade and is arranged on and throws on frame plate; The described number that throws blade is 2-8, and two relative to throw the hypsokinesis angle A that blade throws frame plate be relatively 3-8 °, other two relative to throw the hypsokinesis angle B that blade throws frame plate be relatively 7-12 °.The utility model, compared with other noise-reduction methods, is not affecting under the prerequisite that throws efficiency, have financial cost low, be easy to realize, easy construction, and can obtain good noise reduction.
Description
Technical field
The utility model belongs to the device field that throws, and specifically, particularly a kind of low noise throws device.
Background technology
Vane type throws device due to simple in structure, reliable operation, easily adjust and maintenance, traffic capacity are strong and the advantage such as low cost of manufacture, is widely used on agricultural fibrous materials results and processing equipment.Focused on its power consumption more, threw efficiency and threw the performance figure such as distance throwing the design of device in the past, and its Low Noise Design was paid little attention to.The noise sending when this machine work is found in actual measurement according to noise is up to 100-110dB left and right, the noise producing not only hinders language, the communication etc. of operating personal in production to exchange and the Organization And Management of impact production, thereby but also the physical and mental health of heavy damage operating personal reduces work efficiency etc.Along with the raising of people's living standard, the reinforcement of environmental consciousness, the promulgation of national noise emission new standard, machinery noise has become a key factor of restriction product design.Therefore research and develop low noise, the high efficiency device that throws becomes important subject.
Utility model content
In order to address the above problem, the utility model provide a kind of reasonable in design, financial cost is low, be easy to realize, easy construction, and the low noise that can obtain good noise reduction throws device.
For addressing the above problem, the technical scheme that the utility model adopts is:
A kind of low noise throws device, comprises and throws shell, it is characterized in that: described in throw in shell and be provided with and throw impeller mechanism, and throw shell and be communicated with discharging mechanism; The described impeller mechanism that throws comprises and throws frame plate and throw blade, throws the frame plate external power supply that is in transmission connection, and throws blade and is arranged on and throws on frame plate; The described number that throws blade is 2-8, and two relative to throw the hypsokinesis angle A that blade throws frame plate be relatively 3-8 °, other two relative to throw the hypsokinesis angle B that blade throws frame plate be relatively 7-12 °.
As a kind of technical scheme of optimization, described in throw blade number be 4.
As a kind of technical scheme of optimization, described two relative to throw the hypsokinesis angle A that blade throws frame plate be relatively 5 °, and other two relative to throw the hypsokinesis angle B that blade throws frame plate be relatively 10 °.
As a kind of technical scheme of optimization, described discharging mechanism comprises the discharging straight tube and the discharging elbow that are communicated with successively, and the connection of discharging straight tube throws shell.
As a kind of technical scheme of optimization, the flaring hole exits that the outer end outlet of described discharging elbow is 1: 10 for gradient.
As a kind of technical scheme of optimization, described in to throw shell biside plate wall thickness be 4mm; The wall thickness that throws shell Circular Shell, discharging straight tube and discharging elbow is 3mm.
As a kind of technical scheme of optimization, described in to throw impeller be 13mm with the diameter clearance that throws shell.
Owing to having adopted technique scheme, compared with prior art, the utility model throws structure, shape and the size of device by improvement, reduce the aerodynamics noise and the vibration noise that throw in work, improve and throw efficiency, and compared with other noise-reduction methods, have financial cost low, be easy to realize, easy construction, and can obtain good noise reduction.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail simultaneously.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the impeller mechanism that throws of a kind of embodiment of the utility model.
Detailed description of the invention
Embodiment:
As shown in Figure 1 and Figure 2, a kind of low noise throws device, comprise and throw shell 2, described in throw in shell 2 and be provided with and throw impeller mechanism 1, and throw shell 2 and be communicated with discharging mechanism.The described impeller mechanism 1 that throws comprises and throws frame plate 5 and throw blade 6, throws frame plate 5 external power supply that is in transmission connection, and throws blade 6 and is arranged on and throws on frame plate 5.The described number that throws blade is 2-8, and two relative to throw the hypsokinesis angle A that blade throws frame plate be relatively 3-8 °, other two relative to throw the hypsokinesis angle B that blade throws frame plate be relatively 7-12 °.
Consider the needs of noise reduction, described in throw blade number be 4, be a kind of selection of the best.Meanwhile, described two relative to throw the hypsokinesis angle A that blade throws frame plate be relatively 5 °, and other two relative to throw the hypsokinesis angle B that blade throws frame plate be relatively 10 °.
Described discharging mechanism comprises the discharging straight tube 3 and the discharging elbow 4 that are communicated with successively, and 3 connections of discharging straight tube throw shell 2.The flaring hole exits that the outer end outlet of described discharging elbow 4 is 1: 10 for gradient.It is described that to throw shell 2 biside plate wall thickness be 4mm; The wall thickness that throws shell 2 Circular Shells, discharging straight tube 3 and discharging elbow 4 is 3mm.The described impeller 1 that throws is 13mm with the diameter clearance that throws shell 2.
The utility model throws structure, shape and the size of device by improvement, reduce the aerodynamics noise and the vibration noise that throw in work, improve and throw efficiency, and compared with other noise-reduction methods, have financial cost low, be easy to realize, easy construction, and can obtain good noise reduction.
The utility model is not limited to above-mentioned preferred implementation, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or akin technical scheme, all belong to protection domain of the present utility model.
