Description

Technical Field

[0001] The invention relates to the field of distributor equipment, in particular to a distributor made by hot molding of a fully-encapsulated structure for chemical industry. Background Art

[0002] A distributor refers to a liquid distribution device installed at the top of a packed tower. Its function is to evenly distribute the liquid in the cross section of the tower, thereby ensuring high-efficiency operation. Commonly used operating distributors include: showerhead type, impact type, pagoda type, porous row pipe type, porous coil type, overflow plate type and overflow trough type. When the spray liquid flows downward along the packing layer, it cannot maintain the original uniform distribution state and flows to the tower wall, affecting the contact between the gas and liquid phases and reducing the mass transfer efficiency. Therefore, the packing layer must be segmented, and a liquid redistribution device must be installed between the two packing layers so that the liquid can flow evenly to the lower layer. The existing distributors are relatively simple in function. Summary of the invention

[0003] The invention aims to provide a distributor made of full-covered structure by hot molding for chemical industry.

[0004] In order to achieve the above object, the technical solution of the present invention is:

[0005] A distributor made of hot-molded fully-enclosed structure for chemical use, comprising an outer shell and an inner shell, wherein the inner shell is arranged inside the outer shell, and the outer shell can rotate relative to the inner shell, and the longitudinal sections of the outer shell and the inner shell are in a "convex" shape, and the outer shell and the inner shell are both hollow structures with an opening at the upper end; a first sealing ring is fixedly connected to the inner surface of the upper part of the outer shell, and a sealing groove is provided on the outer surface of the upper part of the inner shell, the first sealing ring and the sealing groove cooperate with each other, and a plurality of first through holes are provided on the lower outer periphery of the inner shell; a plurality of second through holes are provided on the bottom of the inner shell, a plurality of third through holes are provided on the lower outer periphery of the outer shell, and a plurality of fourth through holes are provided on the bottom of the outer shell, and when the first through hole is opposite to the third through hole, the second through hole and the fourth through hole are staggered, and when the second through hole is opposite to the fourth through hole, the first through hole and the third through hole are staggered.

[0006] Furthermore, a second sealing gasket is fixedly connected to both the first through hole and the second through hole, the second sealing gasket is annular, and the width of the portion of the second sealing gasket extending beyond the first through hole is greater than the distance between the outer periphery of the inner shell and the inner surface of the outer shell.

[0007] Furthermore, the edges of the third through hole and the fourth through hole on one side close to the inner shell are rounded.

[0008] Furthermore, the first sealing gasket is a hollow structure, an inflation valve core is fixedly connected to the outer shell, and the interior of the first sealing gasket is connected to the outside through the inflation valve core.

[0009] Furthermore, a rotating ring is fixedly connected to the upper inner surface of the outer shell, and a sliding groove is provided on the upper outer periphery of the inner shell, and the rotating ring and the sliding groove cooperate with each other.

[0010] Furthermore, the inner shell includes an upper feeding part and a lower dividing part, the feeding part and the dividing part are integrally formed, the sealing groove and the sliding groove are arranged on the feeding part, and the first through hole and the second through hole are arranged on the dividing part; the outer shell includes an upper rotating part and a lower control part, the rotating part and the control part are integrally formed, the rotating ring and the first sealing gasket are arranged on the rotating part, and the third through hole and the fourth through hole are arranged on the control part.

[0011] Compared with the prior art, the present invention has the following advantages and positive effects:

[0012] The outer shell of the present invention can rotate relative to the inner shell. When the first through hole is opposite to the third through hole, the second through hole and the fourth through hole are staggered. When the second through hole is opposite to the fourth through hole, the first through hole and the third through hole are staggered. Different cloth directions can be selected by rotating the outer shell to achieve a one-machine-multiple-purposes effect. The present invention is provided with a second sealing ring in the first through hole and the second through hole. After the outer shell rotates, the second sealing ring can play a sealing role to prevent the material from seeping out of the first through hole and the second through hole. The present invention is also provided with an adjustable first sealing ring. When the outer shell rotates, the gas inside the first sealing ring can be discharged to facilitate the rotation of the outer shell. After the rotation, the gas is injected into the first sealing ring to compress the inner shell, thereby preventing the outer shell from rotating and improving stability.
