Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] Example 1:

[0030] Reference Figures 1-4 This first embodiment of the present invention discloses a coolant circulation device for valve plate processing, including a coolant storage tank 1, a storage cavity inside the coolant storage tank 1, and coolant (preferably water-based coolant, capacity 50-200L) filled at the bottom of the storage cavity. A receiving hopper 11 (tilted at an angle of 30-45°) connected to the storage cavity is installed on the top of the coolant storage tank 1. A delivery pump 15 (flow rate 30-100L / min, head 10-20m) with its input end connected to the storage cavity is installed on the outer wall of the coolant storage tank 1. A cooler 2 (cooling power 1-5kW, using the compressor refrigeration principle) is installed on the outer wall of the coolant storage tank 1.

[0031] Supplementary explanation of the working principle of refrigerator 2:

[0032] Refrigerator 2 adopts a vapor compression refrigeration cycle system, specifically including:

[0033] Compressor: Compresses low-temperature, low-pressure refrigerant gas into high-temperature, high-pressure gas (pressure 1.5-2.5MPa).

[0034] Condenser: High-temperature gas is cooled and condensed into high-pressure liquid here (air-cooled or water-cooled, with heat dissipation power matching cooling capacity).

[0035] Expansion valve: High-pressure liquid is throttled and depressurized into a low-temperature, low-pressure two-phase fluid (pressure drop to 0.3-0.5 MPa);

[0036] Evaporator: Low-temperature refrigerant absorbs heat from the coolant and evaporates into gas (heat exchange temperature difference 5-8℃);

[0037] Refrigerant: R134a or R404A environmentally friendly refrigerant is preferred, with a charge of 0.5-2 kg;

[0038] Control system: Employs PID regulation, with temperature control accuracy of ±1℃;

[0039] Additional technical parameters:

[0040] Total power: 3-10kW (including refrigeration, conveying, and rotating systems);

[0041] Noise level: ≤65dB(A);

[0042] External dimensions: Length 1200-2000mm × Width 800-1200mm × Height 1000-1500mm;

[0043] Applicable ambient temperature: 5-40℃;

[0044] Filtration efficiency: ≥95% (particle size > 0.5mm debris);

[0045] Maintenance cycle: Cleaning and maintenance are required after 200-400 hours of continuous operation.

[0046] The cooler 2 is independently equipped with a circulating pump. The coolant is drawn from the input end of the cooler 2 and returned to the storage chamber through the output end (temperature difference controlled ±2℃). A rotating roller 32 (speed adjustable from 10-30 rpm) is rotatably installed in the storage chamber. Several filter collection boxes 33 (4-8 in number, filter screen aperture 0.5-2mm) are detachably installed on the outer roller wall of the rotating roller 32. The filter collection boxes 33 are made of 304 stainless steel woven mesh (mesh count 40-60 mesh). Two auxiliary slag discharge baffles 35 (stainless steel material, height 10-20mm) are fixedly installed on the back of each filter collection box 33. Metal debris falling from the back of the filter collection boxes 33 is detachably installed in the storage chamber.

[0047] Example 2:

[0048] Reference Figures 1-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: the back of the coolant storage tank 1 has an installation port (the size of which is adapted to the back plate 12). Several installation blocks (spacing 200-300mm) are fixedly installed on the inner wall of the installation port. The back plate 12 (thickness 5-10mm) is embedded in the installation port and fits against the surface of the installation blocks. The back plate 12 is rotatably installed with one end of the rotating roller 32 (with bearing cooperation). Screws 13 (M6-M8 specifications) are detachably installed between the back plate 12 and the installation blocks. A fixing seat 14 (height adapted to the receiving box 4) is vertically fixed on the inner wall of the storage cavity. An inlet and outlet (with sealing strip) are opened through the outer wall of the coolant storage tank 1 through the storage cavity. The receiving box 4 (volume 5-10L) is slidably inserted into the inlet and outlet.

[0049] The top of the fixed base 14 has two sliding grooves (15-25mm wide). The bottom of the receiving box 4 has two sliders 41 (with self-lubricating bearings) fixedly installed. The two sliders 41 are slidably installed in the sliding grooves respectively. When the two sliders 41 abut against the inner wall of the corresponding sliding groove, the side wall of the receiving box 4 is flush with the outer wall of the coolant storage tank 1 (tolerance ±0.5mm). A handle 42 (anti-slip design) is fixedly installed on the side wall of the receiving box 4.

[0050] The input end of the cooler 2 is connected to a liquid extraction pipe 21 (inner diameter 20-40mm), and the output end of the cooler 2 is connected to a drain pipe 22 (with the same inner diameter). The liquid extraction pipe 21 extends to the bottom of the storage chamber (50-100mm from the bottom), and the drain pipe 22 is positioned above the liquid extraction pipe 21 (height difference 200-300mm). A motor 31 (power 0.5-1.5kW, IP54 protection rating) is vertically fixedly installed on the front of the coolant storage tank 1. The output end of the motor 31 is fixedly connected to the rotating roller 32 via a coupling (concentricity ≤0.1mm). The outer roller wall of the rotating roller 32 has several dovetail grooves (slope 1:10). Several filter collection boxes 33 are fixedly installed with dovetail strips 34 (tolerance fit H7 / g6) near one end of the rotating roller 32. Several dovetail strips 34 are slidably inserted into the corresponding dovetail grooves (fitting clearance 0.1-0.3mm).

[0051] The remaining structure is the same as that in Example 1.

[0052] The complete workflow of the coolant circulation equipment used for valve plate processing is as follows:

[0053] Initial separation of coolant and debris

[0054] The processed coolant, carrying metal shavings, enters the storage chamber through the receiving hopper 11;

[0055] The coolant naturally passes through the filter structure of the filter collection box 33 under the action of gravity;

[0056] Metal debris is effectively intercepted and temporarily stored by filter collection box 33;

[0057] Dynamic filtration and debris collection

[0058] Motor 31 drives rotating roller 32 to rotate at a constant speed (recommended speed 15-20 rpm), see the attached instruction manual. Figure 3 From the perspective of rotation, it appears to be counter-clockwise.

[0059] The filter collection box 33 rotates synchronously with the rotating roller 32;

[0060] When the filter collection box 33 is rotated to a specific angle (approximately 120°-180°);

[0061] Centrifugal force causes the temporarily stored metal debris to detach from the filter screen;

[0062] The auxiliary slag discharge baffle 35 guides the debris to fall accurately into the receiving box 4;

[0063] Coolant circulation system operation

[0064] The filtered clean coolant settles at the bottom of the storage chamber;

[0065] Pump 15 delivers coolant to the processing area;

[0066] The cooler 2 draws a portion of the coolant through the liquid extraction pipe 21 to cool down the unit.

[0067] The cooled liquid returns to the upper part of the storage chamber through the drain pipe 22;

[0068] Maintenance and cleanup mechanism

[0069] The receiving box 4 adopts a drawer-type design and can be easily pulled out using the handle 42;

[0070] The filter collection box 33 can be quickly disassembled and assembled via the dovetail strip 34;

[0071] The backplate 12 can be removed for comprehensive in-depth maintenance.

[0072] Continuous operation capability

[0073] Rotary filtration and centrifugal slag discharge are carried out simultaneously;

[0074] Achieve true non-stop operation;

[0075] The processing efficiency is more than 40% higher than that of traditional equipment.

[0076] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
