Description

Technical Field

[0001] The utility model relates to the field of chemical production equipment, in particular to a neopentyl glycol production heating device. Background Art

[0002] Neopentyl glycol is a white crystalline solid that is odorless and hygroscopic. It is mainly used in the production of unsaturated resins, oil-free alkyd resins, polyurethane foams and elastomers as plasticizers, surfactants, insulating materials, printing inks, inhibitors, and additives for synthetic aviation lubricants. In the chemical process of neopentyl glycol production, the neopentyl glycol crystals need to be heated.

[0003] Existing heating devices often heat neopentyl glycol by direct heating. Since neopentyl glycol is placed in a pile during heating, it often causes uneven heating of the neopentyl glycol. If the temperature is too high, it is easy to spontaneously ignite, and if the temperature is too low, it is difficult to achieve production efficiency. Utility Model Content

The electric heating tube heats the liquid between the raw material barrel and the heating barrel, and the partition is used to conduct the heat of the liquid to the neopentyl glycol to heat the neopentyl glycol. When the raw material barrel rotates, the partition can be used to disturb the liquid, so that the heat of the liquid can be evenly conducted to the neopentyl glycol through the partition. When the raw material barrel rotates, the partition provided can also stir the neopentyl glycol in the raw material barrel. The raw materials can allow the neopentyl glycol to be heated evenly. After the heating is completed, the heating barrel can be rotated on the bracket so that the discharge pipe is facing the bottom of the bracket.

[0032] refer to Figure 1-Figure 5 , a neopentyl glycol production heating device, comprising:

[0033] Bracket 100;

[0034] The heating barrel 101 is arranged on the bracket 100. A raw material barrel 102 is arranged in the heating barrel 101. A rotating shaft 103 extending to the outside of the heating barrel 101 is connected to one side of the raw material barrel 102.

[0035] A plurality of openings 104 are provided on the outer wall of the raw material barrel 102, and a plurality of partitions 105 are slidably connected in the openings 104;

[0036] A plurality of electric heating tubes 106 are disposed in the heating barrel 101;

[0037] The discharge pipe 107 is provided at one end of the raw material barrel 102 and extends to the outside of the heating barrel 101;

[0038] A rotating component, provided on the heating barrel 101, for rotating the raw material barrel 102;

[0039] A moving component is provided on the heating barrel 101 and is used to move the partition 105. The moving component can open the discharge pipe 107 when the partition 105 is moved to a preset position;

[0040] By setting up the heating barrel 101, when in use, clean water can be poured into the heating barrel 101, and the neopentyl glycol to be heated can be poured into the raw material barrel 102. In the initial state, the discharge pipe 107 is in a closed state, and the multiple partitions 105 are protruding from the inner wall of the raw material barrel 102. The raw material barrel 102 is rotated by a rotating component and the electric heating tube 106 is turned on. The electric heating tube 106 heats the liquid between the raw material barrel 102 and the heating barrel 101, and the partition 105 is used to conduct the heat of the liquid to the neopentyl glycol to heat the neopentyl glycol. When the raw material barrel 102 rotates, the partition 105 can be used to disturb the liquid, so that the heat of the liquid can be evenly conducted to the neopentyl glycol through the partition 105. When the raw material barrel 102 rotates, the partition 105 set can also be used to stir the raw material barrel 102. The raw material of neopentyl glycol in the barrel 102 can make the neopentyl glycol heated evenly. After the heating is completed, the heating barrel 101 can be rotated on the bracket 100 so that the discharge pipe 107 is facing the bottom of the bracket 100, and the position of the partition 105 is moved by the moving component. One end of the partition 105 is flush with the inner wall of the raw material barrel 102. The raw material contaminated on the side wall of the partition 105 can be scraped off by the opening 104, and it will not affect the subsequent discharge. The present application utilizes the partition 105 to conduct the heat of water, and the partition 105 moves the raw material, so that the raw material can be evenly heated, which solves the problem that the heating device in the prior art is stacked when heating the neopentyl glycol, which often leads to uneven heating of the neopentyl glycol, easy spontaneous combustion when the temperature is too high, and difficulty in achieving production efficiency when the temperature is too low.

[0041] As a further feature of the present invention, a feed pipe 200 rotatably connected to the shaft 103 is provided in the shaft 103, a support bar 201 connected to the feed pipe 200 is connected to one side of the heating barrel 101, and a liquid inlet pipe 202 connected to the support bar 201 is communicated to one side of the heating barrel 101;

[0042] By setting up the liquid inlet pipe 202, cleaning liquid can be poured into the heating barrel 101 through the liquid inlet pipe 202. After the pouring is completed, the liquid inlet pipe 202 can be closed to prevent water from flowing out. The set feed pipe 200 can facilitate operators to pour neopentyl glycol crystals into the raw material barrel 102, and will not affect the position of the feed pipe 200 when the raw material barrel 102 rotates.

[0044] By setting the spring 206, the set spring 206 can limit the position of the partition 105, ensuring that one end of the partition 105 always protrudes from the inner wall of the raw material barrel 102 in the initial state. When the position of the partition 105 needs to be moved, the position of the top ring 204 can be moved. The movement of the top ring 204 can move the position of the partition 105 through the wedge-shaped opening 203, thereby utilizing the opening 104 to scrape off the neopentyl glycol contaminated on the side wall of the partition 105.

[0045] As a further feature of the present invention, a tube body 300 is fixedly sleeved in the discharge tube 107, and a plurality of discharge ports 301 are opened on the outer wall of the tube body 300.

[0046] By setting up the cylinder 304, when in use, the push plate 302 can be moved by utilizing the movement of the telescopic shaft of the cylinder 304. The movement of the push plate 302 can drive the sealing plug 303 and the connecting rod 305 to move. The sealing plug 303 moves away from the discharge port 301. At this time, the neopentyl glycol material in the raw material barrel 102 can be released from the discharge port 301. When the connecting rod 305 moves, it can drive the top ring 204 to move, thereby achieving the purpose of opening the discharge port 301 when the partition 105 moves to the preset position.
