Description

TECHNICAL FIELD

[0001] The utility model relates to cold storage condensate pan bottom ice melting heating, especially cold storage condensate pan heating bracket. BACKGROUND

[0002] The refrigerant in the food cold storage evaporator runs at a lower evaporation pressure, and the corresponding evaporation temperature is also lower. For example, the temperature of the meat storage room is -16 DEG C to -20 DEG C, and the evaporation temperature of the evaporator is even lower than -25 DEG C. The water vapor inside the food often freezes on the surface of the evaporator, and the longer the time, the thicker the ice, which greatly reduces the refrigeration effect. To maintain good refrigeration effect, the evaporator needs to be defrosted regularly.

[0003] However, the inventors of the present application found at least the following technical problems in the process of implementing the technical solutions of the embodiments of the present application:

[0004] The ice melting uses an electric heating rod heating method, which allows the melted ice water to collect in the condensate pan of the evaporator and then flow along the drain pipe. If smaller ice crystals cannot flow away and collect in the water pan, the bottom of the condensate pan is flat and cannot be installed with a heating belt. With repeated ice melting, the ice collects higher and higher, and finally forms an ice column against the blades of the fan, causing current overload and burning out the fan. The above behavior not only delays the construction period, but also increases the safety hazard. Therefore, a hard heat tracing belt bracket needs to be designed to heat and melt ice at the bottom of the condensate pan to ensure the safe operation of the fan. SUMMARY

[0005] In order to solve the problems existing in the prior art, the cold storage condensate pan heating bracket is provided to solve the problem of safety hazard caused by ice melting and collecting in the evaporator condensate pan. The bracket is arranged on the top of the frame, and the two ends of the frame are provided with winding support pipes. The electric heat tracing belt can be bent on the winding support pipe and circulate winding, and is arranged in an array on the bearing plate to form a heating assembly on the bottom of the condensate pan to heat and melt ice, solving the technical problem of heating and melting ice in the evaporator condensate pan.

[0006] The technical problem solved by the embodiments of the present application is:

[0007] The cold storage condensate pan heating bracket is installed at the bottom of the condensate pan and includes a frame, a winding support pipe, a bearing plate and an electric heat tracing belt.

[0008] The electric heat tracing belt is used for heating and melting ice in the condensate pan. The frame is the main structure of the bracket and is used to arrange the electric heat tracing belt in an array for heating the condensate pan. The bearing plate is a thin plate arranged on the top of the frame and is used to support the electric heat tracing belt. The winding support pipe is arranged at both ends of the frame, and the electric heat tracing belt is wound on the winding support pipe at one end and extends along the bearing plate to the winding support pipe at the other end. The electric heat tracing belt circulates winding and is arranged on the bearing plate.

[0009] To further solve the technical problems to be solved by the embodiments of the present application, the bearing plate provided by the embodiments of the present application is provided with a circular hole in the middle of the bearing plate, which is used for installing a drain pipe of a condensate pan to pass through and discharge melted ice water.

[0010] Further, a space is reserved between the winding support pipe and the bearing plate, the bearing plate on the frame is higher than the winding support pipe, and the bearing plate and the winding support pipe have a 30° included angle.

[0011] Still further, the frame top is arrayed with a cross beam, the cross beam is arrayed with a top wire, the rotating top wire 12 extends upward, passes through the top of the frame to support the bearing plate, so that the electric heat tracing band held by the bearing plate can contact the bottom of the condensate pan.

[0012] Still further, the electric heat tracing bands are uniformly distributed on the bearing plate, and the spacing between the electric heat tracing bands is 40 mm.

[0013] Positive effects, the technical scheme provided in the embodiments of the present application has at least the following technical effects or advantages:

[0014] 1. Since the embodiments of the present application adopt the technical means of arranging the bearing plate on the top of the frame and arranging the winding support pipe at both ends of the frame, the electric heat tracing band can be bent on the winding support pipe to circulate and be arrayed on the bearing plate to form an array, effectively solving the technical problem of safety hazards caused by ice melting and collection of the condensate pan in the prior art, and realizing the technical effect of applying the electric heat tracing band to heat and melt ice.

[0015] 2. Since the embodiments of the present application adopt the technical means of arranging the top wire on the cross beam at the top of the frame, the top wire installed on the cross beam is upwardly supported to make the bearing plate protrude under stress and hold the electric heat tracing band close to the bottom of the condensate pan, effectively solving the technical problem of safety hazards caused by ice melting and collection of the condensate pan in the prior art, maintaining the heating temperature, and realizing the technical effect of improving the thermal efficiency.

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Although the embodiments of the utility model have been shown and described, it can be understood by those of ordinary skill in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.

[0023] As shown in the figure, the cold storage condensate pan heating bracket is installed at the bottom of the condensate pan and includes a frame 10, a winding support pipe 20, a bearing plate 30 and an electric heat tracing band;

[0024] The electric heat tracing band is used for heating and melting ice of the condensate pan.

[0025] The frame 10 is the structural body of the bracket and is used for laying the array of the electric heat tracing band to heat the condensate pan.

[0026] The bearing plate 30 is a thin plate arranged at the top of the frame 10 and is used for bearing the electric heat tracing band.

[0027] The winding support pipe 20 is arranged at both ends of the frame 10, the electric heat tracing band is wound on the winding support pipe 20 at one end, extends to the winding support pipe 20 at the other end along the bearing plate 30, and is arranged on the bearing plate 30 in a looped manner, so that the electric heat tracing band heats and melts ice at the bottom of the condensate pan, thereby solving the problem of safety hazard caused by the melting ice of the condensate pan.

[0028] In order to ensure the stability of the structure of the embodiment, the bearing plate 30 is provided with a round hole 31 in the middle for installing a drain pipe of the condensate pan to pass through and discharge the melted ice water.

[0029] In order to further ensure the stability of the structure of the embodiment, a space is reserved between the winding support pipe 20 and the bearing plate 30, so that the electric heat tracing band can circulate through the space, facilitating the insertion of the electric heat tracing band and the circulation of the electric heat tracing band on the winding support pipe 20; the bearing plate 30 on the frame 10 is higher than the winding support pipe 20, and the bearing plate 30 and the winding support pipe 20 have an included angle of 30°, facilitating the lifting of the electric heat tracing band by the bearing plate 30.

[0030] In order to optimize the structure of the embodiment, the frame 10 has a cross beam 11 on the top, and a top wire 12 is arranged on the cross beam 11. The rotating top wire 12 extends upward and passes through the top of the frame 10 to support the bearing plate 30, so that the electric heat tracing band lifted by the bearing plate 30 is arranged in an upward convex arrangement, which can contact the bottom of the condensate pan and maintain the heating temperature, thereby applying the electric heat tracing band to heat and melt ice.

[0031] Preferably, the electric heat tracing band is uniformly distributed on the bearing plate 30, and the spacing between the electric heat tracing bands is 40mm.

[0032] The technical solutions in the above embodiments of the application have at least the following technical effects or advantages:

[0033] Since the bearing plate 30 is arranged on the top of the frame 10, and the winding support pipes 20 are arranged at both ends of the frame 10, the electric heat tracing band can be bent on the winding support pipes 20 and circulate around the winding support pipes 20, and can be arranged in an array on the bearing plate 30, thereby forming a heating assembly that covers the bottom of the condensate pan to heat and melt ice.

[0034] Since the top wire 12 is arranged on the cross beam 11 on the top of the frame 10, the top wire 12 installed on the cross beam 11 is upwardly supported, causing the bearing plate 30 to be stressed and protrude, thereby lifting the electric heat tracing band to tightly contact the bottom of the condensate pan, maintaining the heating temperature, improving the thermal efficiency, and solving the problem that the electric heat tracing band is lowered due to gravity, the electric heat tracing band has a gap with the bottom of the condensate pan, and cannot be tightly attached to perform heat transfer.

[0035] In the embodiment, the frame 10 is welded from a white steel pipe, the bearing plate 30 is a white steel plate, and the winding support pipe 20 is a white steel pipe.

[0036] As an alternative to conventional technology, in the present embodiment, the electric heat tracing band is a self-limiting electric heat tracing band, between the two conductive cores is distributed with the heating role of the semiconductor high polymer material, its outside is composed of polymer inner sheath, alloy shielding net and polymer outer sheath. When there is current, with the temperature of the electric heat tracing band rising, the cable resistance rises. As a result, the output power of the electric heat tracing band decreases with the rise of its temperature. Because the heating power changes with the temperature of each place on the electric heat tracing band, the heated semiconductor core material behaves as a variable temperature resistance opposite to the heating temperature high / low change trend. Therefore, the self-limiting electric heat tracing band will not overheat even if it overlaps. The electric heat tracing band is not drawn in the drawings of the specification.

[0037] Working process of the present embodiment:

[0038] First, connect the cold store condensate pan heating bracket with the evaporator condensate pan, the bearing plate 30 is in a relaxed state;

[0039] Secondly, the harder electric heat tracing band is wound from one end of the support pipe 20, the electric heat tracing band laid on the bearing plate 30 extends to the other end of the support pipe 20, the electric heat tracing band is arranged in a cycle, and the number of the electric heat tracing bands distributed on both sides of the round hole 31 on the bearing plate 30 is equal;

[0040] Thirdly, keep the distance between the adjacent two electric heat tracing bands at 40mm;

[0041] Finally, the top wire 12 installed on the cross beam 11 is lifted up, the bearing plate 30 is forced to hold up the electric heat tracing band and the bottom of the condensate pan.

[0042] It is worth mentioning that the contents not described in detail in the specification all belong to the prior art known to those skilled in the art, and the model parameters of the electric heat tracing band are not specifically limited, and can be determined using conventional equipment. In the present technical solution, the electric control elements not mentioned belong to the prior art, and therefore are not shown in the drawings and will not be described here.

[0043] Finally, it should be pointed out that: the above only describes the preferred embodiments of the present utility model, and is not used to limit the present utility model, although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
