Description
Technical field
The utility model relates to a kind of horizontal screw centrifuge, and particularly a kind of noise reduction case of horizontal screw centrifuge belongs to the food apparatus technical field.
Background technology
Horizontal screw centrifuge mainly by high-revolving rotary drum, turn to identical with rotary drum and the auger conveyor, differential mechanism, frame, rotary drum case, motor that have differential with it etc. formed.
In horizontal screw centrifuge when work,, suspension enters in the rotary drum through the inner core discharging opening of auger conveyor in the continuous reader of feed pipe, and under centrifugal action, suspension forms the circular layer liquid level concentric with axis in rotary drum.Solids are settled down to drum inner wall in the powerful centrifugal force field that rotary drum produced of rotation at a high speed.Because the differential action of differential mechanism makes between auger conveyor and the rotary drum and forms relative motion, the solid phase sediment is further dewatered by the dry section that spiral is pushed to the rotary drum small end, discharges through slag notch then.Liquid phase through clarification is discharged through the overfall of rotary drum small end, and solid phase sediment and clarified solution are collected in respectively in the compartment of rotary drum case correspondence, after the gravity discharge.
The rotary drum case of tradition horizontal screw centrifuge, comprise that along extension of horizontal screw centrifuge length direction and cross section be semicircular circular arc housing, the left and right sides two-port of circular arc housing is respectively equipped with first member plate and the right end plate with its sealing, and circular arc housing inner chamber is provided with the compartment that the multiple tracks dividing plate is divided into circular arc housing inner chamber difference in functionality successively along its length direction.The circular arc housing is a single layer structure, and noise is big, and during input and output material, the vibration of case is also bigger; In addition, because the horizontal screw centrifuge feeding temperature is very high, what have reaches about 90 ℃, makes that the outside wall temperature of circular arc housing is also very high, and operating personnel are easy to be scalded.
The utility model content
The purpose of this utility model is, overcomes problems of the prior art, and a kind of noise reduction case of horizontal screw centrifuge is provided, and can effectively reduce the noise and the vibration of case.
For solving above technical problem, the noise reduction case of a kind of horizontal screw centrifuge provided by the utility model, comprise that along extension of horizontal screw centrifuge length direction and cross section be semicircular circular arc housing, the left and right sides two-port of described circular arc housing is respectively equipped with first member plate and the right end plate with its sealing, circular arc housing inner chamber is provided with the compartment that the multiple tracks dividing plate is divided into circular arc housing inner chamber difference in functionality successively along its length direction, described circular arc housing comprises mutually nested internal layer shell and outer casing, be provided with interlayer between described internal layer shell and the outer casing, described interlayer and left and right sides end plate constitute airtight hollow cavity, be full of fine sand in the described hollow cavity, the top of described hollow cavity is provided with at least one and irritates husky mouthful.
With respect to prior art, the utility model has been obtained following beneficial effect: 1. from the approach of noise transmission, the noise that horizontal screw centrifuge produces at first makes the inner layer case body wall produce resonance, and the resonance of inner layer case body wall makes the air of contact with it produce vibration, outwards propagates with the form of sound wave again.Be spaced from each other by interlayer between the internal layer shell of the utility model sound insulation and noise reduction case and the outer casing, the vibration of internal layer shell can not be directly delivered on the outer casing, can only transmit sound wave by means of the air vibration in the interlayer.
From irritate husky mouthful to interlayer, fill fine sand after, most of air is discharged from the interlayer, remains a spot of air and is present in the space of the grains of sand, and the energy of noise is had the absorption damping action.
3. in a single day the space occurs owing to vibrating between sand bed and the housing, because the rapid self-packing of mobile better meeting of fine sand, noise reduction can not decay; The weight that adds sand bed is heavier, and internal layer shell and outer casing are pushed down all by sand bed all the time can't produce resonance, has both reduced the source strength of noise, has cut off the propagation of noise approach again.
4. sand bed is stacking states, and is both closely knit, totally is soft again, and the faint vibration of internal layer is difficult to pass sand bed and arrives at skin.
5. the case vibration that causes of horizontal screw centrifuge input and output material also can have been played the effect of vibration isolation by the effective damping of fine sand interlayer.
6. this sound insulation and noise reduction case is directly transformed on former rotary drum case, adopt the structure of double Shell band fine sand interlayer, the volume that increases on the basis of individual layer case is very little, the corresponding compartment of case inner chamber is collected solid phase sediment and the clarified solution that horizontal screw centrifuge produces respectively, the function that had both satisfied in producing is used, and has sound insulation and decrease of noise functions again.
7. this sound insulation and noise reduction case is compared with inner walls subsides sound-absorbing material, and the utility model has more the intensity height, simple and stable structure, the advantage that long service life and cost are low.Sand bed uses more closely knit and more closely knit, problems such as sound-absorbing material comes off, performance degradation can not occur.
8. because the feeding temperature of horizontal screw centrifuge is very high, after case adopted interlayer and fills fine sand, the temperature of circular arc housing outer wall can reduce greatly, prevents that the operative employee from being scalded.
As preferred version of the present utility model, the husky mouth of described filling is positioned at a side end panel top of described hollow cavity.End plate is dull and stereotyped, and Guan Shakou is arranged on end plate and relatively is easy to processing, has also guaranteed the integrality of circular arc housing.
As preferred version of the present utility model, described filling is provided with two for husky mouthful, is positioned at the both sides of place end plate peak side by side.Be provided with two and irritate husky mouthful, can be simultaneously irritate husky mouthful to the lateral irrigation sand at place separately from two, it is fast to irritate husky speed.
As preferred version of the present utility model, the top of described hollow cavity is provided with at least one ventilation mouth.After ventilation mouth is set, be beneficial to the discharge of unnecessary air, make filling sand become more smooth and easy, be beneficial to the discharge of the air that expands because of being heated in the use again.
As preferred version of the present utility model, described ventilation mouth is positioned at and irritates husky mouthful of relative opposite side end plate top.Ventilation mouth is separately positioned on the relative both sides end plate with Guan Shakou, is beneficial to arrange and processing, also is beneficial to the discharge of air when irritating husky.
