Specifically, the avoidance holes 27 are multiple, and the cross bar 10 of the transmission member 8 is arranged above the avoidance holes 27 and is attached to the avoidance holes 27 so as to seal the tops of the avoidance holes 27, thereby avoiding dust from entering the positions of the avoidance holes 27 to the upper part of the mounting frame 19.
It should be noted that, in the conventional installation manner of the bag cage 2, the bag cage 2 is directly inserted into the interior, so that the radial dimension of the bag cage 2 is slightly smaller than the radial dimension of the cloth bag, after the bag cage 2 is inserted into the interior of the cloth bag, the cloth bag is still in a loose state, after the flue gas enters the interior of the housing 1, under the pressure of the flue gas, the cloth bag and the bag cage 2 will be rubbed relatively, which is easy to cause abrasion of the cloth bag, and as a further embodiment of the present invention, the second support rod 4 is provided with the protruding portion 28. Specifically, in this embodiment, a virtual cylinder is formed between the top ring 6 and the bottom plate 7, when the second support rod 4 is placed at the edge position of the bottom plate 7, the distance between the protruding portion 28 and the central axis of the bottom plate 7 is greater than the radial dimension of the bottom plate 7, that is, the protruding portion 28 protrudes from the outer circumferential surface of the virtual cylinder, so that when the bag cage 2 is installed, the second support rod 4 is placed at a position close to the central axis of the bottom plate 7, at this time, the second support rod 4 is stored inside the virtual cylinder so as to facilitate the insertion of the bag cage 2 into the cloth bag, after the bag cage 2 is completely inserted into the cloth bag, the second section 22 is pulled so that the second section 22 slides in the direction of the connecting rod 26, and the second section 22 is connected with the connecting rod 26, during which the first section 21 and the second support rod 4 are driven to move in the direction away from the central axis of the bottom plate 7, so that the protruding portion 28 protrudes from the outer circumferential surface of the virtual cylinder, and the protruding portion 28 abuts against the inner circumferential surface of the cloth bag, so that the cloth bag is supported from the inside the cloth bag, and the bag is kept in a tight state, thereby friction between the bag cage 2 and the cloth bag is avoided as much as possible, and the service life of the bag is prolonged.
The above-mentioned scheme of manually pulling the second section 22 to move requires one hand to fix the position of the second section 22, and the other hand to connect the second section 22 with the connecting rod 26, which is inconvenient to operate, and in order to solve the above-mentioned problem, it is preferable that the wedge-shaped surface 29 is provided on the first connecting member 20, the connecting rod 26 is provided with the abutting rod 30, and the abutting rod 30 is located on the movement stroke of the first connecting member 20. Specifically, the wedge surface 29 is disposed on the lower surface of the second section 22, and a flexible positioning groove is formed at the end of the wedge surface 29, and a through hole is formed between the support rod 30 and the connecting rod 26, so that the second support rod 4 is disposed in the virtual circle when the bag cage 2 is mounted, the position of the wedge surface 29 and the position of the support rod 30 are correspondingly arranged, and then the bag cage 2 is inserted downwards, so that the wedge surface 29 on the second section 22 is abutted against the support rod 30, and the benefit is that firstly, when the wedge surface 29 is abutted against the support rod 30, the second section 22, the first section 21 and the second support rod 4 are driven to move towards a direction away from the central axis of the bottom plate 7 passively, so that the position of the second support rod 4 is switched passively, secondly, when the wedge surface 29 is abutted against the support rod 30, the support rod 30 enters into the flexible positioning groove, and the second section 22 cannot move horizontally under the action of the flexible positioning groove, so that the subsequent screwing or screwing process is facilitated.
Further, a sliding seat 31 is arranged on the bag cage 2, a second connecting piece 32 is arranged on the second supporting rod 4, and the second connecting piece 32 is in sliding connection with the sliding seat 31. Specifically, the sliding seat 31 is disposed on the inner bottom wall of the bottom plate 7, a transverse slot is disposed in the sliding seat, a second spring 33 is disposed between the lateral wall of the transverse slot and the second connecting member 32, the second connecting member 32 is disposed at the bottom end of the second supporting rod 4, and the second connecting member 32 is slidably connected with the transverse slot, so as to provide a fulcrum for the bottom end of the second supporting rod 4, thereby improving the stability of the second supporting rod 4 during sliding, and when the second supporting rod 4 moves toward the central axis of the bottom plate 7, the second spring 33 is accumulated, and when the second supporting rod 4 moves reversely, the elastic force of the second spring 33 is released to assist the second supporting rod 4 to return.
As shown in fig. 13-15, the range of action of the racket 9 is the first area 34, the range of action of the arc 38 is the second area 35, and the effect of the racket 9 on the second area 35 is smaller than the effect of the racket on the first area 34, so that the cloth bag dust cleaning effect of the second area 35 is poor, as a further embodiment of the present invention, a rotating ring 36 is rotatably arranged on the first support rod 3, a torsion spring (not shown) is arranged between the rotating ring 36 and the first support rod 3, a rotating rod 37 and the arc 38 are fixedly connected on the rotating ring 36, and the rotating rod 37 is located on the moving stroke of the second support rod 4. Specifically, be provided with no less than one rotation ring 36 on the first bracing piece 3 that is close to second bracing piece 4 respectively, and be provided with the spacing structure that recess or bulge loop etc. are used for preventing relative axial displacement between rotation ring 36 and the first bracing piece 3, rotation rod 37 is along the radial arrangement of rotation ring 36, and two adjacent rotation rods 37 stagger in the vertical direction and arrange, arc 38 rigid coupling in rotation ring 36's outer peripheral face, the elasticity of torsional spring is spacing rotation rod 37 on the motion stroke of second bracing piece 4, and make arc 38 set up in the position that keeps away from second region 35, and second region 35 is located the rotation stroke of arc 38, the effect that so set up lies in, when the deashing to the sack, can make second bracing piece 4 slide towards rotation rod 37, and make second bracing piece 4 and rotation rod 37 butt, thereby drive rotation ring 36 through rotation rod 37, and then drive arc 38 and rotate towards the direction of second region 35, and collide with it, and to beat second region 35, thereby can be improved by the elasticity of holding up the arc 38, thereby the second region 35 is reset, and the second torsion spring is rotated by the arc 37 and reset, when the second region is reset, the arc 4 is reset, and the second is rotated and the arc 37 is rotated and is reset.
The embodiment of the invention also provides a black method adsorption method for the asphalt fume, which comprises the black method adsorption device for the asphalt fume, and further comprises the following steps of S1, spraying and cooling, S2, adsorption (the cooled fume is introduced into an adsorption reactor and the adsorption impurity removal is realized through carbon powder), S3, bag dust removal, S4 and RTO (which are equipment for treating organic waste gas and volatile organic compounds and are used for converting the waste gas into harmless substances through high-temperature oxidative decomposition), and S5, wet desulfurization.
While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that modifications may be made to the described embodiments in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive of the scope of the invention, which is defined by the appended claims.
