Abstract

A container for liquid is provided with means for heating the liquid. The electrical heating elements 9 are provided on the outer wall of the container and provided with a control and safety unit. The heating elements are arranged in box-shaped housings. These housings 5 are arran­ged between steam pipes which are normally arranged parallel on the outer peripheral wall on existing containers. The invention provides a heating system by means of standard elements which can be mounted on existing containers.

Description

  • The invention relates to a container for liquid pro­vided with means for heating a liquid. For heating of liquid held in the container use has been made up to the present time of for instance an electrical heating arranged in the container in the form of an electrical rod-like heating ele­ment guided through the container. The drawback to this form of heating is that the heating has a highly local character, which is a disadvantage in the case of use with liquids having poor heat transfer.
  • Another form of a much used heating is by means of an electrical heating mounted on the outside of the tank wall. This heating consists of mats. The mats usually con­sist of long elements with an outer jacket of nickel steel and a hard copper core. These systems are very moisture sensitive and not chemically resistant. The repair costs for these systems are very high.
  • In addition steam heating is widely used. This system can only be applied in stationary position.
  • The invention has for its object to provide an extremely simple heating system which provides advantages such as rapid distribution of heat and the use of standard elements.
  • This is achieved according to the invention in that these means consist of electrical heating elements placed along a portion of the outer peripheral wall and each arran­ged in a housing of stainless steel. By arranging a number, for example 24, of such electrical heating elements on the outside of the container body a well distributed heating of the container is achieved such that for instance within one hour after switching on the desired temperature can be reached. Preferably used as heating element is that element that is used in the container industry as standard heating element for de-icing cooling elements of the containers. Such elements are in sufficient supply in many parts of the world, also in less developed regions, so that in the case of malfunction rapid replacement can be carried out. All components used for this system are known from refrigerating engineering for containers. Malfunctions can therefore be remedied quickly and efficiently on a world-wide basis.
  • In the case the invention is used on a container having pipes arranged along the peripheral wall for the transport of steam for heating the container, the heating elements are preferably arranged between the pipes. The steam heating does not need to be removed. A control and safety unit is preferably added to groups of heating ele­ments in order to control the supply of electrical energy. For the control a common temperature sensor for a group of heating elements is added to a housing of a heating element. For control purposes the temperature on the tank wall in the direct environment of the heating element is measured, while in addition the temperature of the liquid for heating in the container is measured. By means of the temperature control the temperature is bounded to the maximum permitted value on the tank wall and in the liquid. For safety purposes means are also arranged which, when the element with a temperature sensor becomes inoperative, render inoperative the whole group controlled by this sensor.
  • The invention will be elucidated with reference to the drawings. In the drawings:
    • Fig. 1 shows a perspective view from below of a container according to the invention,
    • fig. 2 is a bottom view, and
    • fig. 3 is a perspective view with broken away parts of an individual heating element.
  • The container 1 is provided in the usual manner with steam pipes 2 arranged on the bottom on the outer wall of the container. The steam pipes are series parallel connected and have a feed conduit 3 and a discharge conduit 4 for steam. According to the invention housings 5 for the heating elements are arranged between the steam pipes. The housing for a heating element is box-shaped and contains an inner wall 6 and an outer wall 7 as well as side walls 8. Inside each housing an electrically conducting rod-like heating element 9 is mounted on three brackets, two of which 10, 11 are visible in the drawing. Feed lines 12 provide the supply of electrical energy to each heating element. Such a heating element is in use for the de-icing of evaporators in refri­geration containers and is eminently suited to operation in a moist environment. To one or several of the housings a temperature sensor can be added for controlling the supply of electrical energy to the associated group of heating elements. A safety device is preferably present which swit­ches off the group if the temperature sensor records abnor­mal values or when the temperature sensor becomes non-opera­tional.
