Referring to FIG. 1, an embodiment of a block grease preheating device is provided.

Structurally, the preheating tank 100 is mainly provided, wherein a feed inlet and a sealing cover for intermittently sealing the feed inlet are arranged at the top of the preheating tank 100, the feed inlet is used for feeding block-shaped grease, and the sealing cover is used for preventing odor generated by melting from diffusing out.

The top of the preheating tank 100 is also provided with a condensing channel for collecting condensed water or volatile gas generated by heating.

As shown, the bottom wall of the preheating tank 100 is tapered, i.e., such that the cross-sectional area within the preheating tank 100 decreases from top to bottom.

On the bottom wall of the preheating pipe, there will be a discharge pipe 110 and a heating zone 120. The heating pipe is used for discharging liquid grease, and a control valve is arranged on the heating pipe to control the proceeding and the interruption of discharging. The heating region 120 is a surface region, which may be a plane, or a sector region, or an annular region.

Correspondingly, a heater is arranged on the inner surface or the outer surface of the bottom wall of the preheating tank 100, and the heater can be in a resistance wire heating mode or a heat conducting oil heating mode.

Conventionally, grease cake is stacked on the bottom wall of the preheating tank 100 and heat is exchanged by direct contact of the heating zone 120 with the grease cake. After the grease is melted into liquid, the liquid grease flows to the discharge pipe 110, the blocky grease descends, new blocky grease contacts the heating area 120 again, and heat exchange is continued.

In order to improve the heating efficiency, in this embodiment, the preheating tank 100 is provided with a spray assembly 200, the spray assembly 200 includes a partition box 210, an oil return pipeline 230 communicating with the partition box 210, a sprayer 220 communicating with one end of the oil return pipeline 230 far away from the partition box 210, an oil return pump 231 located on the oil return pipeline 230, and an induction heater 232, the partition box 210 and the sprayer 220 are located in the preheating tank 100, and the oil return pump 231 and the oil return pipeline 230 are located outside the preheating tank 100.

That is to say, when the liquid, high temperature grease flows to the discharging pipe 110, the grease is not discharged to the next process, under the driving of the oil return pump 231, the liquid, high temperature grease enters the oil return pipeline 230, in the oil return pipeline 230, the liquid, high temperature grease is further heated by the induction heater 232, the heat loss is compensated, then, the liquid, high temperature grease enters the sprayer 220, and flows out from the spraying port 222 in the form of spraying, the liquid, high temperature, fast flowing grease erodes the massive grease, so that the top and the side of the massive grease are all heated in advance, and the massive grease is favorably melted rapidly.

The oil return line 230 can be directly connected to the bottom wall of the preheating tank 100, and conveniently, the oil return line 230 is directly connected to the discharge pipe 110, so that the installation difficulty is reduced.

The preheating tank 100 should also be perforated on its side wall to facilitate the connection of the return line 230 to the shower 220.

The induction heater 232 heats through setting up the induction coil of winding at the oil return pipeline 230, reduces the influence to the grease flow, and power can be adjusted as required, and induction heater 232 and oil return pump 231's order also can be adjusted as required, accords with reality.

Regarding the arrangement of the separation box 210, the separation box 210 is connected and fixed to the bottom wall of the preheating tank 100, the separation box 210 is used for separating the heating area 120 from the discharge pipe 110, a separation cavity is formed inside the separation box 210, the discharge pipe 110 is arranged at the bottom of the separation cavity, the separation box 210 is provided with a grid 211, and the grid 211 is used for enabling grease to flow from the heating area 120 to the discharge pipe 110.

The partition box 210 partitions the heating region 120 from the discharge pipe 110, so that the discharge pipe 110 can be prevented from being blocked by massive grease, and the spraying assembly 200 can work conveniently.

For the arrangement of the sprayer 220, the sprayer 220 is positioned above the separation box 210, and the sprayer 220 is fixedly connected with the side wall of the preheating tank.

On the sprayer 220, a plurality of spray ports 222 are used for spraying liquid grease to the block-shaped grease, and the direction of the spray ports can be directed to the center of the preheating tank 100.

As shown, the preheating tank 100 is provided with an agitator 300, the agitator 300 has an agitating shaft 310 extending up and down, and a driving motor located at the top end of the agitating shaft 310, the driving motor is disposed outside the preheating tank 100, and the bottom end of the agitating shaft 310 is rotatably connected to the partition box 210.

That is, the partition box 210 may also limit the position of the stirring shaft 310, so as to reduce the deflection of the stirring shaft 310.

As shown, the bottom end of the stirring shaft 310 is provided with a stirring paddle 320, and the radial edge of the stirring paddle 320 extends toward the heating area 120.

The radial edge of stirring rake 320 towards heating zone 120 extends the setting, is favorable to increasing the relative heater's of cubic grease removal, conveniently increases the contact of cubic grease and heating zone 120, improves the heat transfer with liquid grease.

In some embodiments, the inner wall of the preheating tank 100 may be provided with a plurality of inclined guide plates 330, a plurality of inclined guide plates 330 are located below the sprayer 220, a plurality of inclined guide plates 330 are located above the stirring paddles 320, and a plurality of inclined guide plates 330 are used for guiding the grease lumps to the stirring paddles 320.

That is, with cubic grease direction stirring rake 320, avoid cubic grease card between the jar wall of stirring rake 320 and preheating tank 100, reduce the jamming, simultaneously, stirring rake 320 also has the crushing effect for cubic grease breaks, more convenient heating melts.

As for the arrangement of the shower 220, a plurality of the shower pipes 221 may be arranged side by side and spirally extending in the up-down direction.

A plurality of shower 221 sets up side by side and extends along upper and lower direction spiral and arranges, enlarges and sprays the space, not only can spray the top of cubic grease, can also form to the side of cubic grease and erode, the reinforcing sprays the heat transfer effect.

Correspondingly, the oil return pipeline 230 should be provided with a plurality of branches to communicate with the spraying pipe 221, so as to meet the spraying requirement.

In some embodiments, the spray openings 222 may also be disposed along the circumference of the preheating tank 100 and biased toward the center of the preheating tank 100, that is, the spray openings 222 are oriented between the circumferential direction and the direction toward the center of the preheating tank 100.

That is, the grease sprayed from the plurality of spray ports 222 is not distributed in a central divergent manner, and is not converged into one strand in the air, so that the spray plane area can be enlarged, and more massive grease can be benefited.

In some embodiments, as shown in fig. 2, a plurality of ribs 223 may be further disposed inside the preheating tank 100. The plurality of ribs 223 are used for fixing one shower pipe 221, and the plurality of ribs 223 are positioned on the top of the shower pipe 221.

Thus, the ribs 223 may also help break up clumps of grease and, at the same time, reduce the impact of clumps of grease on the shower 221, resulting in less failure of the preheating tank 100.

Obviously and profitably, in this embodiment, preheating device is through setting up spray set 200 to, utilize in the preheating tank 100 heated and the liquid grease that melts to come the auxiliary heating blocky grease that has not yet melted in the preheating tank 100, change the single heating mode of original heater and blocky grease contact heating, make the blocky grease in the preheating tank 100 by all-round heating, improve the heat exchange with blocky grease, improve heating efficiency, satisfy the production needs.
