Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.

As shown in fig. 1, the embodiment of the utility model provides a chloroform recovery unit is proposed, including retrieving jar 3, vacuum pump 1 and heat exchanger 2, vacuum pump 1 is arranged in carrying the chloroform gas to heat exchanger 2, retrieve jar 3 and be arranged in retrieving the chloroform liquid after heat exchanger 2 cools off, still including being used for the installation vacuum pump 1's installation component, the installation component includes: install bin 4, supporting seat 6 and elevating system, install bin 4 sets up subaerial, install bin 4 inside is provided with installation cavity 5, elevating system sets up in installation cavity 5, elevating system is used for driving supporting seat 6 and moves in vertical direction, vacuum pump 1 sets up the top at supporting seat 6 fixedly.

The specific working principle is as follows: in the process of producing the trichloromethane gas, firstly, the generated trichloromethane gas is conveyed into a heat exchanger 2 by using a vacuum pump 1, cooling water is introduced into the heat exchanger 2 to cool the trichloromethane gas into liquid, and the liquid trichloromethane is stored in a recovery tank 3. When the vacuum pump 1 needs to be maintained and cleaned, the lifting mechanism in the control installation box 4 drives the supporting seat 6 to move downwards, so that the vacuum pump 1 is lowered to a proper position, and a worker can conveniently maintain and clean the vacuum pump. Through the supporting seat 6 which is arranged to be capable of lifting, the vacuum pump 1 can be conveniently controlled to move in the vertical direction, and therefore accidents of workers during high-altitude maintenance of the vacuum pump 1 are avoided.

Specifically, the vacuum pump 1 is a dry screw vacuum pump. The dry screw vacuum pump is an air pumping device which utilizes a pair of screws to synchronously rotate in opposite directions at high speed in a pump shell to generate air suction and exhaust functions, and certain gaps are formed between the screws, so that the dry screw vacuum pump has no friction between the screws during working, is stable in operation and low in noise, does not need lubricating oil in a working cavity, and is very suitable for gas occasions containing a large amount of water vapor and a small amount of dust. The dry type spiral vacuum pump can be used for recovering the trichloromethane, can meet the requirements of process production, can also be used for recovering clean trichloromethane, can also meet the discharge standard of environmental protection requirements, and does not pollute water and air.

As shown in fig. 1, the lifting mechanism includes: motor 8, backup pad 7 and first gear 10, be provided with backup pad 7 in the installation cavity 5 horizontally, motor 8 passes through mount pad 9 and sets up in installation cavity 5, motor 8 is located the below of backup pad 7, first gear 10 sets up the top at backup pad 7 with rotating, motor 8 is used for driving first gear 10 and rotates, the top of backup pad 7 still is provided with two second gears 11 with rotating, and each second gear 11 all meshes with first gear 10, the bottom of supporting seat 6 is provided with two lead screws 12 symmetrically, and the one end of two lead screws 12 passes install bin 4, second gear 11 and backup pad 7 respectively vertically in proper order, and each lead screw 12 all with the 11 threaded connection of second gear that correspond, each lead screw 12 all with install bin 4 and backup pad 7 sliding connection. The specific working principle is as follows: the motor 8 in the installation box 4 is started, the output shaft of the motor 8 rotates to drive the first gear 10 to rotate, the first gear 10 drives the second gear 11 meshed with the first gear to rotate, and the screw rod 12 is in threaded connection with the second gear 11, so that the screw rod 12 can move up and down in the vertical direction, and the support seat 6 arranged at the top of the screw rod is driven to move up and down. The transmission mode of the gear is adopted, so that the transmission efficiency is higher, the work is reliable, and the service life is longer.

As shown in fig. 2, the installation case 4 includes: the novel LED lamp comprises a body 402 and a baffle 401, wherein an installation cavity 5 is arranged inside the body 402, one side of the installation cavity 5 is provided with an opening, the baffle 401 is detachably arranged in the opening through a clamping assembly, and the baffle 401 is used for sealing the opening. The bottom of the opening is provided with a mounting groove 13, a spring 15 is arranged in the mounting groove 13, a bolt 14 is arranged at the bottom of the baffle 401, the baffle 401 is vertically inserted into the opening from the top of the body 402, the bottom of the baffle 401 is tightly attached to the bottom of the opening, the baffle 401 is slidably connected with the body 402, the bolt 14 is inserted into the mounting groove 13 and tightly attached to the spring 15, and one end, away from the bolt 14, of the baffle 401 is detachably connected with the body 402 through the clamping assembly. Specifically, when the elevating system in the installation cavity 5 needs to be overhauled, open the chucking subassembly, under spring 15's elasticity, bolt 14 leaves mounting groove 13, then to lifting baffle 401's pull handle 17, just can take out baffle 401 to overhaul elevating system, spring 15 and bolt 14's setting can realize the quick purpose of taking out baffle 401.

The clamping assembly is a limiting screw 16, two threaded holes are formed in the two side walls, close to the body 402, of the baffle 401, the two limiting screws 16 are respectively inserted into the corresponding threaded holes horizontally from the two sides of the body 402, and each limiting screw 16 is in threaded connection with the corresponding threaded hole. By rotating the limit screw 16 to release or clamp the baffle 401, the threaded connection mode avoids the situation that the bolt 14 at the bottom of the baffle 401 is popped out of the mounting groove 13 under the elastic force of the spring 15 to accidentally open the opening, so that the opening can be closed more firmly and reliably.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
