Specific embodiment
Technical solution to further illustrate the present invention below with reference to the accompanying drawings and specific embodiments.
Evaporation copper shares double space plate cold-water heat exchanger in shell, including shell 10, drive end bearing bracket 11, front baffle 12, Partition plate 14, rear end cap 13, rear bulkhead 15 and copper pipe;The shell 10 is cylindrical cast iron housing, and shell 10 is first described in multistage Tail, which is connected, to be serially connected and seals;Shell of each section of the shell 10 as the evaporator of a refrigeration system;It is each The shell 10 of section is equipped with refrigerant inlet h, refrigerant outlet c, exhaust outlet e and oil discharge outlet d;The refrigerant outlet c The inside correspondence position positioned at the shell 10 be welded with baffle, which corresponds to the position of the refrigerant outlet c;
The water route of the evaporator of multiple refrigeration systems is shared, refrigerant line then in each individual shell, reduces space It occupies;Baffle causes refrigerant that can only enter refrigerant outlet c from the side of the baffle, in case high pressure causes liquid system when starting Cryogen is directly drained from the refrigerant outlet c.The drive end bearing bracket 11 is buckled in the front baffle 12;The drive end bearing bracket 11 is casting It is integrally formed, including bottom case 111, outer rim 112, shell 113 and Inlet and outlet water partition plate 110, the shell 113 is raised in the bottom case 111, water inlet 114, water outlet 115 are offered on the shell 113;The Inlet and outlet water partition plate 110 is traversed in the bottom case 111 The inside division of the drive end bearing bracket 11 is two parts of intake antrum and water chamber by the left and right in portion;At the edge of the bottom case 111 Several bolts hole 116 are offered, offer several bolts hole again at the edge of the shell 113, these bolts hole are used for Connected with outer casing 10;
Intake antrum and water chamber respectively put together water inlet and water outlet, and drive end bearing bracket 11 has been connected by bolt with front baffle 12 Come, installation manufacture and repair is facilitated to disassemble.The outer ring sealing welding of the front baffle 12 in the shell 10 first end it is outer Circle, and beyond the outer of the shell 10 to form the space of a certain number of bolts hole, and connect with 11 bolt of drive end bearing bracket It connects;The front baffle 12 offers the perforative hole for being used to accommodate copper pipe, and the copper pipe is formed close with expansion tube process through the hole Envelope;The horizontal level at the middle part of the front baffle 12 does not open up to accommodate the hole of copper pipe, the horizontal level be equipped with it is described The corresponding gasket in 110 position of Inlet and outlet water partition plate;
The Inlet and outlet water partition plate 110 of the gasket and upper end cover 11 coordinates, and forms sealing, and the water route for avoiding intake antrum and water chamber is short Road.The spacing board 14 is made of cast iron Q235;It offers the circular hole of the position of the corresponding copper pipe, is worn for the copper pipe It crosses, and will be sealed after the copper pipe tube expansion with the spacing board 14;The spacing board 14 is two ring flanges, respectively with controlling two The shell 10 of side welds, and is flanged joint between the two ring flanges;
When 10 quantity of shell of series connection is more, when whole longer, adjacent shell 10 is connected using two ring flanges, it is possible to When the shell 10 of either segment generates failure, replacement or repair are individually dismantled, so as to improve service efficiency.Moreover, make It can flexibly be increased without limitation according to the requirement of refrigerating capacity or reduce series connection series with flanged joint.The rear end cap Water cavity is formed between 13 and the rear bulkhead 15, the top of the rear end cap 13 sets air bleeding valve, and bottom sets drain valve;
Air bleeding valve is used for releasing pressure automatically during high pressure, ensures safety;Drain valve bleeds off water when needing maintenance.The rear bulkhead 15 The outer ring sealing welding of end face is opened in the outer ring of the second end of the shell 10, the outer ring of the other end of the rear bulkhead 15 Equipped with annular groove, the annular groove accommodates the outer ring of the rear end cap 13;
The copper pipe inside the shell 10, be the first end through the entire shell 10, second end, front baffle 12, Whole pipe of spacing board 14 and rear bulkhead 15.
Forming sealing using annular groove can be more firm.
The baffle is apart from the refrigerant outlet c between 2cm-4cm.
