Abstract
The utility model discloses a sand temperature regulator comprising a sand box (1), temperature reduction pipes (2), circulation pipes and sands (4), wherein the temperature reduction pipes (2) are arranged in the sand box (1) in a distributing way; one end of each temperature reduction pipe (2) is a water inlet, while the other end of each temperature reduction pipe is a water outlet; the water inlet and the water outlet of each temperature reduction pipe (2) are respectively positioned and connected on two ends of one circulation pipe outside the sand box (1); the sand box (1) is internally filled with the sands (4); and the outer wall of each circulation pipe is welded with cooling fins (3). In the utility model, the temperature of circulation water of a regulator is reduced by utilizing underground low-temperature soil, and then the temperature of the sands is reduced by utilizing the low temperature of the circulation water through the sand temperature regulator; and the utilization of clean renewable energy is beneficial to energy conservation and emission reduction.
Description
Technical field
The utility model relates to sand temperature modulator.
Background technology
Foundry enterprise is regulated the common way of sand temperature: one, supporting corresponding cooling tower and cooling circulating water system in the sandbox regulator system, the high-temperature water of sand temperature modulator circulating water outlet enters the cooling tower radiating and cooling, and then recycles.This mode summer because the outdoor temperature height, cooled circulating water temperature is generally at 28-36 ℃, therefore a lot of times can not be satisfied the technological requirement of sand temperature modulator, the temperature of reclaimed sand can't be reduced to the scope of 10-25 ℃ technological requirement, for reaching technological requirement, often reduce circulating water temperature by adding ice cube in the system, can satisfy technological requirement though do like this, but increased the cost input, and system will consume great amount of water resources at circulation time, need constantly system to be replenished running water,, therefore be unfavorable for energy-saving and emission-reduction to keep the balance of system; Two, the refrigeration plant and the sand temperature modulator of purchase special use are supporting, the high-temperature water of sand temperature modulator circulating water outlet has special-purpose refrigeration plant to force cooling, enter the circulation of sand temperature modulator again, this method advantage is a good refrigeration effect, the sand temperature control is guaranteed, shortcoming is that the one-time investment of equipment is big, and the operation and maintenance cost height, and is less economical.
Summary of the invention
The purpose of this utility model is: a kind of sand temperature modulator is provided, utilize the soil of underground low temperature that the recirculated water of adjuster is lowered the temperature, utilize the low temperature of recirculated water the sand temperature to be implemented cooling again, utilize the regenerative resource of cleaning, help energy-saving and emission-reduction by sand temperature modulator.
Technical solution of the present utility model is: this sand temperature modulator comprises sandbox, cooling pipe, circulation pipe and sand grains, the cooling of arranging in sandbox is managed, one end of cooling pipe is a water inlet, the other end of cooling pipe is a delivery port, the water inlet of cooling pipe is connected respectively on the two ends that are positioned at the outer circulation pipe of sandbox with delivery port, fills sand grains in the sandbox.
Wherein, on the outer wall of cooling pipe, weld fin.
During installation, the circulation pipe landfill is in surface soil, and circulation pipe is communicated with tap water supply system; During use, when the low temperature running water in the underground circulation pipe at the cooling pipe that under major cycle or effect, enters in the sandbox at water circulating pump, heat exchange takes place by cooling Guan Yuqi in the high temperature sand that is positioned at sandbox, makes the temperature rise of low temperature tap water to 16-17 ℃, makes simultaneously below the sand temperature drop to 27 ℃; Running water after the intensification is got back in the circulation pipe through the cooling pipe, and the underground with low temperature in circulation pipe carries out heat exchange, makes its temperature get back to 15 ℃ low-temperature condition, enters next circulation again.
The utlity model has following advantage: 1, utilize the soil of underground low temperature that the water in the circulation pipe is lowered the temperature, utilize water at low temperature that the sand temperature is implemented cooling again, heat exchange moves under airtight environment, therefore can not produce any influence, energy-conserving and environment-protective to tap water supply system; 2, the sand temperature of high temperature sand is generally at 50-60 ℃, differs 35-45 ℃ with the temperature of low temperature running water, so cooling rate is very fast, improved the efficient of sand temperature modulator greatly; 3, utilize the regenerative resource of cleaning, at 10-27 ℃, the assurance sand mold hardens and forms the sufficient time with the sand temperature control; 4, the outer wall of the cooling pipe of sand temperature modulator design fin increases sand grains and cooling pipe contact area and time, the heat exchanger effectiveness height; 5, the soil of underground low temperature replaces cooling tower and cooling circulating water system, and cost of investment is low; 6, summer underground and water body temperature be 8-15 ℃, the temperature at underground 1.8m place is substantially constant at 15 ℃, surface soil and water body are huge dynamic power balance sysmtes, the relative equilibrium that the soil on the face of land and water body keep energy to accept and disperse naturally, the scope of its fluctuation is far smaller than the change of air, because of its temperature is lower and constant, so can guarantee that sand temperature modulator is reliable, stable.
Description of drawings
Fig. 1 is a structure diagram of the present utility model.
Among the figure: 1 sandbox, 2 cooling pipes, 3 fin, 4 sand grains.
The specific embodiment
Further specify technical solution of the present utility model below in conjunction with accompanying drawing.
As shown in Figure 1, this sand temperature modulator comprises sandbox 1, cooling pipe 2, circulation pipe and sand grains 4, the cooling of arranging in sandbox 1 manages 2, one end of cooling pipe 2 is a water inlet, the other end of cooling pipe 2 is a delivery port, the water inlet of cooling pipe 2 is connected respectively on the two ends that are positioned at the circulation pipe outside the sandbox 1 with delivery port, fills sand grains 4 in the sandbox 1.
Wherein, welding fin 3 on the outer wall of cooling pipe 2.
During installation, the circulation pipe landfill is in surface soil, and circulation pipe is communicated with tap water supply system; During use, when the low temperature running water in the underground circulation pipe at the cooling pipe 2 that under major cycle or effect, enters in the sandbox 1 at water circulating pump, the high temperature sand grains 4 that is positioned at sandbox 1 is by cooling pipe 2 and its generation heat exchange, make the temperature rise of low temperature tap water to 16-17 ℃, make simultaneously below the sand grains temperature drop to 27 ℃; Running water after the intensification is got back in the circulation pipe through cooling pipe 2, and the underground with low temperature in circulation pipe carries out heat exchange, makes its temperature get back to 15 ℃ low-temperature condition, enters next circulation again.
