废气净化主要是指针对工业场所产生的工业废气，诸如粉尘颗粒物、烟气烟尘、异味气体、有毒有害气体进行治理的工作。常见的废气净化有工厂烟尘废气净化、车间粉尘废气净化、有机废气净化、酸碱废气净化、化工废气净化以及臭气除臭净化等。由于废气产生情况多样化，很多废气成分复杂，往往不同时间段产生的废气成分都不同，给处理时造成较大的影响，导致废气处理无法达到需要的效果，不利于环境保护。
基于废气的加工环境不同，其处理时面对的场景也有区别，特别是在高温产生的废气处理中，很多时候在过滤排放时，过滤处理不及时内压会突然增加，从而会造成过滤排放堵塞的问题。
发明内容
本发明的目的在于提供一种防爆式废气过滤排放筒，以解决上述背景技术中提出的问题。
为实现上述目的，本发明提供如下技术方案：
一种防爆式废气过滤排放筒，包括筒体，所述筒体一端通过螺纹配合活动装配连接设置有进气端盖，所述筒体外围贯穿设置有多组排气通孔，所述进气端盖中镶嵌设置有自清洁式过滤机构，所述筒体内安装设置有伸缩式过滤机构，所述伸缩式过滤机构远离进气端盖的一端和筒体内壁限位滑动配合，且和筒体内壁之间限位连接，所述筒体远离进气端盖的末端嵌入设置有和所述伸缩式过滤机构对应适配的泄压端。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
实施例1
请参阅图1～3，本发明实施例中，一种防爆式废气过滤排放筒，包括筒体1，所述筒体1一端通过螺纹配合活动装配连接设置有进气端盖2，所述筒体1外围贯穿设置有多组排气通孔，所述进气端盖2中镶嵌设置有自清洁式过滤机构，所述筒体1内安装设置有伸缩式过滤机构，所述伸缩式过滤机构远离进气端盖2的一端和筒体1内壁限位滑动配合，且和筒体1内壁之间限位连接，所述筒体1远离进气端盖2的末端嵌入设置有和所述伸缩式过滤机构对应适配的泄压端。
所述自清洁式过滤机构包括贯穿所述进气端盖2中部的进气口3，所述进气口3表面镶嵌有金属网，所述进气口3靠近筒体1一侧的外围转动连接设置有轴承座4，所述轴承座4中安装设置有波轮叶片5，所述波轮叶片5靠近进气口3一侧均布设置有多组刷毛6，所述刷毛6和所述进气口3上的金属网活动相抵。气流通过进气口3进入到筒体1中，气流吹动波轮叶片5带动轴承座4转动，同时波轮叶片5上的刷毛6能够在气流通过进气口3时不断清刷进气口3中金属网侧面，避免污垢或漂浮物等堵住进气口3而影响废气排放。
所述伸缩式过滤机构包括固定在筒体1内壁的固定环7以及套接在所述固定环7远离进气端盖2一侧边缘的波纹滤布筒8，所述波纹滤布筒8呈压缩状态，所述波纹滤布筒8远离固定环7的末端固定连接设置有垫板9，所述垫板9中部嵌入设置有和泄压端对应适配的弹性泄压阀，所述垫板9两端对称连接设置有滑块15，所述滑块15滑动配合连接在筒体1两侧内壁上，且所述滑块15通过熔断螺栓16固定在筒体1内壁上，所述滑块15也可以通 过弹簧弹性连接在筒体1侧壁上。废气通过进气口3初步截留大尺径杂质后，通过固定环7进入到波纹滤布筒8中过滤，波纹滤布筒8过滤后杂质积留在波纹滤布筒8中，气流通过筒体1上的排气通孔排出，随着废气排量增加或是废气温度突然升高，滑块15能够在筒体1中滑动，波纹滤布筒8被拉伸后能够扩大过滤排气面积，提高排气效率，从而提高安全性，随着气压继续增加，弹性泄压阀和泄压端对应配合，则进一步泄压排气，可以提高废气过滤排放时的安全性。
所述筒体1两侧对称嵌入设置有滑动轨道12，所述滑动轨道12内两侧对称嵌入设置有限位轨道13，所述限位轨道13断面呈半圆形，所述滑块15和所述滑动轨道12滑动配合，所述滑块15两侧对称活动嵌入设置有和限位轨道13对应滑动配合的滚珠17，所述滑块15上端转动连接设置有滚轮18，所述滚轮18活动抵合在所述滑动轨道12内顶部。波纹滤布筒8在伸长时，滑块15能够通过滚珠17和滚轮18在滑动轨道12中滑动，这样的配合阻力更小也更加灵敏。
所述排气通孔包括覆盖在波纹滤布筒8压缩状态外围的多组第一透气孔11以及覆盖在滑动轨道12范围内的多组第二透气孔14，在常规废气处理状态下，废气通过波纹滤布筒8过滤排放，而在增压状态下可以利用第二透气孔14增加排放途径，提高排气效率。
实施例2
请参阅图1、4和5，本发明实施例中，一种防爆式废气过滤排放筒，在实施例1的基础上，所述弹性泄压阀包括贯穿设置在垫板9中部的泄压口10以及贴合设置在泄压口10上的封堵板19，所述封堵板19位于泄压口10靠近波纹滤布筒8的一侧，所述封堵板19两端固定连接设置有滑动杆20，所述滑动杆20滑动贯穿所述垫板9，且滑动杆20末端固定连接设置有限位片21，所述限位片21和所述垫板9之间连接设置有支撑弹簧22，所述支撑弹簧22为压缩弹簧所述支撑弹簧22套设在所述滑动杆20外围。平时封堵板19贴合在泄压口10上，能够避免废气未经过滤排放，当垫板9被波纹滤布筒8伸长推动至泄压端一侧时，此时内压过大容易造成危险，封堵板19被泄压端推动并使得滑动杆20在垫板9上滑动，支撑弹簧22被压缩，此时封堵板19和泄压口10之间形成缝隙，方便气流通过泄压口10泄出，从而提高排气效率，也能极大的提高装置使用的安全性。
所述泄压端包括贯穿设置在所述筒体1末端的第三透气孔23，所述第三透气孔23中固定连接设置有支架24，所述支架24为“十字形”结构或是“米字形”结构，所述支架24上固定连接设置有顶杆25，所述顶杆25和所述封堵板19相对设置。当封堵板19接触到顶杆25时，顶杆25推动封堵板19，从而废气可以通过泄压口10排出并从第三透气孔23排放，结构简单，限压方式灵活且便于操作，可以更好的保证废气处理时的安全性，便于根据实际使用场景进行选择。
本发明使用到的标准零件均可以从市场上购买，异形件根据说明书的和附图的记载均可以进行订制，各个零件的具体连接方式均采用现有技术中成熟的螺栓、铆钉、焊接等常规手段，机械、零件和设备均采用现有技术中，常规的型号，加上电路连接采用现有技术中常规的连接方式，在此不再详述。
对于本领域技术人员而言，显然本发明不限于上述示范性实施例的细节，而且在不背离本发明的精神或基本特征的情况下，能够以其他的具体形式实现本发明。因此，无论从哪一点来看，均应将实施例看作是示范性的，而且是非限制性的，本发明的范围由所附权利要求而不是上述说明限定，因此旨在将落在权利要 求的等同要件的含义和范围内的所有变化囊括在本发明内。不应将权利要求中的任何附图标记视为限制所涉及的权利要求。
此外，应当理解，虽然本说明书按照实施方式加以描述，但并非每个实施方式仅包含一个独立的技术方案，说明书的这种叙述方式仅仅是为清楚起见，本领域技术人员应当将说明书作为一个整体，各实施例中的技术方案也可以经适当组合，形成本领域技术人员可以理解的其他实施方式。
