Description

Technical Field

[0001] The utility model belongs to the technical field of polyether polyol preparation, in particular to a refining tower for preparing polyether polyol. Background Art

[0002] Polyether polyol (abbreviated as polyether) is an organic polymer, which is obtained by polyaddition reaction of initiator (compound containing active hydrogen group) with ethylene oxide (EO), propylene oxide (PO) and butylene oxide (BO) in the presence of catalyst. The polyether with the largest output is produced by using glycerol (propylene glycol) as initiator and epoxide (generally PO and EO are used together). By changing the feeding method of PO and EO (mixed or separate), the feeding ratio and the feeding order, various general-purpose polyether polyols are produced.

[0003] The problem with the prior art is that when a refining tower is used to prepare polyether polyols, a high temperature will be generated on the surface of the refining tower, which can easily cause burns if touched by a person, so corresponding protective measures need to be taken for the refining tower. However, traditional devices can no longer meet people's daily work needs. Therefore, we propose a refining tower for preparing polyether polyols. Utility Model Content

[0006] As a preferred embodiment of the utility model, the protective component includes an annular shell, which is fixedly connected to one end of the refining tower surface, and both ends of the annular shell surface are fixedly connected with a card shell, and two groups of annular plates are detachably connected in the annular shell.

[0011] As a preferred embodiment of the utility model, the three groups of support rods are fixedly connected with sliding rods, the surfaces of the three groups of sliding rods are sleeved with springs, one ends of the three groups of springs are fixedly connected with clamping plates, and baffles are detachably connected between the corresponding two groups of clamping plates and the mounting plates, and the baffles are used to protect the refining tower.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model is designed with a refining tower, a protective component, a sieve plate and a feed end. When in use, the material will enter the interior of the refining tower from the feed end. After entering the interior, it will be filtered by the sieve plate. In the process of preparing polyether polyols, a lot of heat will be generated on the surface of the refining tower, which can easily scald nearby personnel. Therefore, the protective component can be used to block the refining tower to prevent people from approaching the refining tower, thereby achieving the effect of protecting the refining tower and people.

[0014] 2. The utility model is designed with a card shell, a card block, a positioning rod, a fixed plate, a nut, a screw, a rotating shaft, a top plate, a limiting rod and a rotating block. When in use, the card block at one end of the annular plate is carded into the inside of the card shell, and then the rotating block is rotated to make the screw rotate using the rotating shaft. During the rotation, the nut will be driven to move downward, and the limiting rod will limit the downward movement of the nut to prevent the nut from rotating with the screw, thereby driving the positioning rod on one side of the fixed plate to be positioned inside the card block, thereby achieving the effect of facilitating the fixing of the annular plate on the surface of the annular shell.

[0015] 3. The utility model is designed with an annular shell, annular plate, supporting rod, mounting plate, baffle, clamping plate, sliding rod and spring. After the annular plate is installed, the baffle is installed inside the corresponding two sets of mounting plates. Then the spring will push the clamping plate to slide on the surface of the sliding rod.

Both ends of the surface of the annular shell 211 are fixedly connected with a card shell 201, and two groups of annular plates 212 are detachably connected in the annular shell 211; both ends of the two groups of annular plates 212 are fixedly connected with a card block 202 corresponding to the card shell 201, and the upper surface of the card shell 201 is fixedly connected with a limit rod 209, and the upper end of the limit rod 209 is fixedly connected with a top plate 208; one side of the lower surface of the top plate 208 is fixedly connected with a rotating shaft 207, and a screw 206 is commonly provided between the rotating shaft 207 and the card shell 201, and one end of the screw 206 is fixedly connected with a rotating block 210.

[0025] The above scheme is adopted: through the design of the card shell 201, the card block 202, the positioning rod 203, the fixed plate 204, the nut 205, the screw 206, the rotating shaft 207, the top plate 208, the limiting rod 209 and the rotating block 210, when in use, the card block 202 at one end of the annular plate 212 is carded into the inside of the card shell 201, and then the rotating block 210 is rotated to make the screw 206 rotate using the rotating shaft 207. During the rotation process, the nut 205 will be driven to move downward, and the limiting rod 209 will limit the downward movement of the nut 205 to prevent the nut 205 from rotating with the screw 206, thereby driving the positioning rod 203 on one side of the fixed plate 204 to be positioned inside the card block 202, thereby achieving the effect of facilitating the fixing of the annular plate 212 on the surface of the annular shell 211.

[0026] refer to Figure 3 A nut 205 is commonly provided between the screw rod 206 and the limiting rod 209, and both sides of the surface of the nut 205 are fixedly connected with fixed plates 204, and the lower surfaces of the two groups of fixed plates 204 are fixedly connected with positioning rods 203, and the two groups of positioning rods 203 are used to fix the position of the block 202; three groups of support rods 213 are fixedly connected to the surfaces of the two groups of annular plates 212, and one side of the surfaces of the three groups of support rods 213 is fixedly connected to the mounting plate 214; sliding rods 217 are fixedly connected inside the three groups of support rods 213, and springs 218 are sleeved on the surfaces of the three groups of sliding rods 217, and one end of the three groups of springs 218 is fixedly connected with a clamping plate 216, and a baffle 215 is commonly and detachably connected between the corresponding two groups of clamping plates 216 and the mounting plate 214, and the baffle 215 is used to protect the refining tower 1.

[0027] The above scheme is adopted: through the design of the annular shell 211, the annular plate 212, the support rod 213, the mounting plate 214, the baffle 215, the clamping plate 216, the slide bar 217 and the spring 218, after the annular plate 212 is installed, the baffle 215 is installed inside the corresponding two sets of mounting plates 214, and then the spring 218 will push the clamping plate 216 to slide on the surface of the slide bar 217. After sliding to a certain position, the clamping plate 216 will be clamped on the surface of the baffle 215 to fix the position of the baffle 215. The baffle 215 can protect the refining tower 1 and at the same time block the people nearby to prevent people from approaching the refining tower 1, thereby effectively preventing people from being scalded by the temperature on the surface of the refining tower 1.

When sliding to a certain position, the clamping plate 216 will be clamped on the surface of the baffle 215 to fix the position of the baffle 215. The baffle 215 can protect the refining tower 1 and at the same time block the people next to it to prevent them from approaching the refining tower 1.
