Description

TECHNICAL FIELD

[0001] The utility model relates to heat exchange equipment technical field, concretely relates to a plate heat exchanger for emulsion pump station. BACKGROUND

[0002] Emulsion pump station is an important equipment in the hydraulic support system of fully mechanized coal mining face, which is responsible for providing high pressure emulsion to drive the hydraulic support to work. Emulsion is mixed by water, emulsified oil and possible additives in a certain proportion, which is used for transmitting pressure, lubrication and cooling. During long time operation, the temperature of emulsion will rise due to the heat generated by the machine running, which not only affects the stability and efficiency of the hydraulic system, but also accelerates the deterioration of emulsion, reduces its lubrication and corrosion resistance.

[0003] In order to solve this problem, emulsion pump station is usually equipped with cooling system, and plate heat exchanger is a common cooling equipment. The working principle of plate heat exchanger is that a group of thin metal plates (usually made of stainless steel or other corrosion resistant materials) are stacked together to form a plurality of narrow flow channels. Emulsion flows in these flow channels, while cooling medium (usually cold water or air) flows on the other side or between the plates, and the two are heat exchanged through the plates to reduce the temperature of emulsion.

[0004] The traditional heat exchanger lacks filter assembly, so that the impurities or precipitates in the emulsion or cooling liquid entering the heat exchanger are directly passed into the heat exchanger without filtration, which blocks the heat exchange with the extension of use time, resulting in low heat exchange efficiency of the heat exchanger, so that it cannot be used normally. UTILITY MODEL CONTENTS

[0006] To solve the above-mentioned technical problems, this utility model provides a plate heat exchanger for an emulsion pump station, including a fixed bracket. A heat exchange assembly is mounted inside the fixed bracket. The heat exchange assembly includes multiple stacked and interconnected heat exchange plates mounted inside the fixed bracket. Each heat exchange plate is divided into two non-communicating chambers by a partition. Each chamber has an inlet and an outlet. Except for the bottom heat exchange plate, the lower part of each heat exchange plate has a connecting pipe communicating with its chamber. The connecting pipe on the upper heat exchange plate is inserted into the inlet or outlet of the lower heat exchange plate's chamber, which is coaxial with the inlet or outlet. Both the inlet and outlet have internal... Equipped with a filter assembly, including a detachable filter cartridge installed inside the inlet or outlet, this invention uses the filter assembly on the heat exchanger to filter and block the emulsion or coolant entering the heat exchanger, ensuring that the emulsion or coolant entering the heat exchanger can be efficiently recycled. This solves the problem of traditional heat exchangers lacking a filter assembly, where impurities or sediments in the emulsion or coolant enter the heat exchanger directly without filtration, causing blockages over time and resulting in low heat exchange efficiency and malfunction. This invention significantly improves the heat exchange efficiency and service life of the heat exchanger.

[0007] The fixing bracket includes a base plate and a mounting plate disposed on the base plate. The base plate has mounting holes, and multiple heat exchange plates are mounted between the mounting plate and the base plate.

[0008] The card is made of tin bronze plate.

[0009] The bottom of the filter cartridge has multiple filter holes.

[0010] The filter cartridge has at least two handles on the top.

[0011] The outer wall of the filter cartridge is provided with external threads, and the inlet and outlet are provided with internal threads that are compatible with the external threads.

Moreover, the removable filter cartridges inside the inlet and outlet can filter and block impurities in the liquid, preventing them from entering the cavity of the heat exchange plate, thus avoiding the problem of reduced heat exchange efficiency and affecting its normal use.
