Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to a heat exchanger field especially relates to a baffling bars for heat exchanger.
[ background of the invention ]
The heat exchanger is an energy-saving device for transferring heat between materials between two or more fluids with different temperatures, and is used for transferring heat from the fluid with higher temperature to the fluid with lower temperature to make the temperature of the fluid reach the index specified by the process so as to meet the requirements of process conditions, and is also one of main devices for improving the utilization rate of energy. The heat exchanger industry relates to more than 30 industries such as heating ventilation, pressure vessels, reclaimed water treatment equipment, chemical industry, petroleum and the like, and an industrial chain is formed mutually.
Referring to chinese patent No. 201020686717.3, a heat exchanger structure in the prior art is disclosed, which includes: casing, pipe case, tube sheet, heat exchange tube and baffle device, baffle device is the baffling bars, the baffling bars all welds mutually with the baffling circle by many baffling bar parallel distribution and baffling bar's both ends, and the defect of this kind of baffling bars structure lies in: because the baffling pole is longer, and both ends all weld mutually with the baffling circle, consequently can't guarantee that the intermediate position of baffling pole is in straight very state to influence the poling of later stage heat exchange tube, one end welds earlier when the baffling pole welds, then welds the other end under the pretension state, in the twinkling of an eye in the welding, the pretightning force of baffling pole is lost under leading to red hot state, leads to the baffling pole can't be straight very.
Therefore, there is a need to provide a baffle grid that solves the above mentioned technical problems.
[ Utility model ] content
In order to solve the above problem, an object of the present invention is to provide a deflecting bar capable of ensuring the middle position of the deflecting bar to be in a straight state.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a baffle grid comprising: baffling circle and a plurality of baffling pole, the one end and the baffling circle of baffling pole weld mutually, the other end of baffling pole is equipped with the external screw thread, the baffling circle is equipped with a plurality of locating piece, the locating piece is equipped with the external screw thread matched with internal thread with the baffling pole, the outside of locating piece is equipped with the external screw thread matched with fastener with the baffling pole.
Preferably, a baffle grid in the present invention is further configured to: the positioning block is a first nut, the first nut is welded with the baffle ring, and the fastener is a second nut.
Preferably, a baffle grid in the present invention is further configured to: the size of the second nut is smaller than that of the first nut.
Preferably, a baffle grid in the present invention is further configured to: the plurality of baffle rods are arranged in parallel at equal intervals.
Preferably, a baffle grid in the present invention is further configured to: the positioning blocks are arranged on the deflection ring at equal intervals.
Preferably, a baffle grid in the present invention is further configured to: the rod baffle is made of round steel.
Preferably, a baffle grid in the present invention is further configured to: the baffle ring is made of steel plates.
Compared with the prior art, the utility model discloses following beneficial effect has: the utility model provides a baffling bars simple structure, simple to operate through with baffling rod one end design for welding mutually with the baffling circle, the other end design is for passing through threaded connection with the baffling circle to can ensure the straight deflection of baffling rod intermediate position, make things convenient for the poling of later stage heat exchange tube.
[ description of the drawings ]
